Description
Technical Field
The invention relates to the field of clothes drying cabinets, in particular to a clothes drying device and method.
Background
In modern life, people have higher and higher requirements on life quality, and especially have high requirements on the comfort level of clothes. In China, most areas in winter are relatively cold, particularly in wide areas in the south, the shady and cool wet areas, and in addition, in middle and lower reaches of Yangtze river, a long period of plum rain season exists, and clothes washed in such a day are difficult to dry thoroughly. Secondly, more and more buildings are built in the city, the illumination time of buildings at lower levels is shorter, and clothes cannot be aired outdoors, so that the city image is influenced. Furthermore, when clothes are dried in a humid weather, bacteria are easy to breed, and the health of a baby in swaddling or a person with a weak constitution is seriously influenced. People often dry the clothes by means of fire or an electric heater, and if the operation is not proper, the clothes are easily damaged, and if the operation is serious, a fire hazard can be caused.
The conventional clothes drying cabinet has two main heating modes, namely an electric heating clothes dryer and a heat pump clothes dryer, wherein the electric heating clothes dryer heats ambient air into dry hot air with proper temperature, so that the dry hot air flows through the surface of wet clothes under the blowing of a fan, water evaporated from the clothes is taken away, and the clothes are dried quickly. The electric heating type clothes dryer has short drying time, but has high heating temperature, easily damages clothes fibers and has high power consumption. The heat pump type clothes dryer mainly heats the circulating air through the compressor, so as to dry clothes, has low power consumption and low heating temperature, is not easy to damage clothes fibers, but has the defects of long drying time and relatively low working efficiency. The electric heating clothes dryer and the heat pump clothes dryer have the common defects that the heaters heat surrounding air through heat conduction, and then dry clothes through hot air, so that the part of the clothes close to a hot air inlet is firstly dried, the part of the clothes close to a return air inlet is not easy to dry, the clothes are required to be continuously dried, and the part of the clothes close to the air inlet is excessively dried, so that the heating effect is uneven, the drying speed of the clothes is greatly influenced by the position in the cabinet body, even drying dead corners occur, and the heating is uneven.
Far infrared itself is an energy-transferring electromagnetic wave having a wavelength of 0.47 to 400 μm between the infrared spectrum and the invisible spectrum. The heat transfer form of the far infrared ray is radiation transfer heat energy, and a medium is not required to be utilized. And the carbon fiber electric heating plate can emit far infrared rays.
Therefore, the existing clothes drying cabinet mostly adopts a carbon fiber electric heating plate as a heating body, the carbon fiber electric heating plate can be processed into a plate-shaped structure, and the heating area is large and the heating is uniform. The carbon fiber electric heating plate has the heating function of heat radiation besides heating through heat conduction, and emits far infrared rays during working, so that the carbon fiber electric heating plate has better penetrating power and high heating speed. The heat energy conversion efficiency is up to more than 99%, and the energy-saving effect is obvious. Meanwhile, far infrared rays can also play a certain role in sterilization and disinfection, so that the far infrared health-care tea is also beneficial to the maintenance of human health.
However, the existing clothes drying cabinet adopting the carbon fiber electric heating plate generally has two disadvantages:
(1) the first is that the carbon fiber electric heating plate is usually arranged on the inner wall of the cabinet body and is far away from clothes, so that uneven heating is caused.
(2) Secondly, the carbon fiber electric heating plates are large in laying area on the inner wall of the cabinet body, and a certain carbon fiber electric heating plate cannot be independently opened, so that once the cabinet is started, all the carbon fiber electric heating plates can be electrified to enter a working state, energy waste is caused when a small amount of clothes are required to be dried, and the cost of a user is greatly increased. In addition, even if a certain carbon fiber electric heating plate can be independently started, the distance between the carbon fiber electric heating plate and clothes at different positions in the cabinet body is unequal due to the fact that the carbon fiber electric heating plate is arranged on the inner wall, and uneven drying can be caused.
The utility model with the Chinese application number of 201220245792.5 discloses a fanless carbon fiber clothes dryer which adopts a cabinet type structure and comprises a box body, a carbon fiber plate, a clothes airing rod, a humidity control device and a cloth cover. Carbon fiber plates are hung in cloth covers on the left side and the right side of the box body, porous insulating cloth is adopted at the bottom, air outlet holes which are arranged in parallel are arranged at the top, and the cloth covers are made of heat insulating materials; the suspended carbon fiber plate is used as a heating source, so that the multifunctional health care physiotherapy chair is energy-saving, safe, reliable and convenient to disassemble, and has remarkable health care physiotherapy effects due to the ultra-strong far infrared rays emitted by the carbon fibers.
The utility model with the Chinese application number of 200620114408.2 discloses a carbon fiber electric heating clothes drying cabinet, which comprises a cabinet body, wherein the cabinet body is provided with an exhaust door and an air inlet door, and the exhaust door is provided with an exhaust fan; the top end in the cabinet body is provided with a clothes hanger, and the inside of the cabinet body is provided with a carbon fiber electric heating plate; the side wall of the cabinet body is provided with a temperature and humidity controller which is connected with the carbon fiber electric heating plate and the exhaust fan through circuits. Air enters the cabinet body through the air inlet door, is heated by the carbon fiber electric heating plate, and dries wet clothes; when the cabinet body reaches a certain temperature and humidity, the working state of the exhaust fan is controlled through the temperature and humidity controller, and the humidity is exhausted. The device is good in drying effect, simple and convenient to operate, energy-saving, power-saving, safe and reliable.
Above-mentioned two patents all adopt the carbon fiber electric plate, but it all will set up the carbon fiber electric plate setting on cabinet internal wall, and is inhomogeneous with the clothing distance to can't open the work alone.
In addition, for the control method of automatic drying of the clothes drying cabinet, two modes are often adopted in the prior art, one mode is simple timing drying, namely, a preset working time is set in advance, and the work of the clothes drying cabinet stops working when the set working time is reached, and the mode often causes that clothes are damaged by excessive drying or the clothes are not dried sufficiently and need secondary drying, so that inconvenience is brought to users. The other method is to set temperature and humidity sensors and judge whether to stop working or not by detecting the temperature and humidity of the air in the cabinet body.
The existing clothes drying cabinet has the defects that the distance between the carbon fiber electric heating plate and clothes is not uniform, the carbon fiber electric heating plate has larger area and can not be independently started to work, and the clothes drying cabinet has more complex control method and higher controller cost. Therefore, there is a need for a clothes drying apparatus and method that overcomes the above-mentioned disadvantages.

Detailed Description
The existing clothes drying cabinet is characterized in that a plurality of carbon fiber electric heating plates are arranged on the inner wall of the cabinet body, the heating plates are of an integral structure and cannot be independently started, and the heating plates on the inner wall of the heating plates are completely heated by electrifying during working, so that the clothes drying cabinet is suitable for being used when more clothes are placed in the clothes drying cabinet. However, if only a small amount of clothes need to be dried, the heating plate is completely started to cause waste of a heat source, and meanwhile, because the carbon fiber electric heating plate is arranged on the inner wall of the cabinet body, the clothes close to the inner wall are heated more, the clothes positioned at the central position are heated less, and uneven drying is caused, which is mainly caused by uneven heat radiation due to unequal distances between the carbon fiber heating plate and the clothes.
The embodiment of the invention provides a clothes drying device which is provided with a heating plate and can be independently opened, and the distance between the heating plate and clothes is equal.
As shown in fig. 1, 2 and 5, a clothes drying device comprises a cabinet body 1 and a cabinet door 2, wherein the cabinet body 1 is provided with an air inlet 12 and an air outlet 11, a plurality of extractable partition boards 3 are arranged between two inner side walls of the cabinet body 1 at intervals from top to bottom, and two inner side walls of the cabinet body 1 are provided with slide rails 4 matched with the partition boards 3. The number of the partition boards 3 can be any number according to the size and actual needs of the clothes drying cabinet, and the embodiment takes the case of three partition boards as an example, but the invention is not limited to the embodiment.
After the arrangement, the heating circuit is skillfully arranged on the partition board 3 in the embodiment of the invention, and the partition board 3 is a pluggable movable partition board, so that the heating circuit is independently started, when the partition board 3 is pulled out of the cabinet body 1, the pair of contact electrodes 6 arranged on the contact surface of the partition board 3 and the cabinet body 1 or the slide rail 4 is disconnected, and the heating circuit stops working. After the partition board 3 is inserted into the installation position along the slide rail, the partition board 3 is contacted with a pair of contact electrodes 6 on the contact surface of the cabinet body or the slide rail 4, and the heating circuit is conducted to start working. Therefore, the working number of the heating circuits in the cabinet body can be controlled through the installation number of the partition plates 3, and the independent starting of each heating circuit is realized, so that the total heating power can be flexibly controlled. The drying requirement of a large amount of clothes can be met, and energy waste caused by the fact that the heating circuits are completely started when less clothes are dried can be avoided.
When the clothes drying device is used specifically, the partition boards 3 with corresponding quantity can be installed according to the quantity of clothes to be dried, and the rest partition boards 3 are drawn out. When more clothes need to be dried, the rest of the partition boards 3 are inserted into the cabinet body 1. The embodiment of the invention arranges the heating circuit on the partition board, and has the advantages of equal distance between the heating circuit and clothes and uniform heating. Because cabinet 1 inner space is cut apart into a plurality of heating spaces by baffle 3, when drying more clothing, will place the clothing layering on every baffle, avoided appearing a large amount of clothing and piled up the condition of placing or concentrate a large amount of clothing to concentrate and hang, the problem that the clothing drying effect of intermediate position is poor.
Because the distances between the clothes of each layer and the upper and lower clapboards 3 where the clothes are located are equal, the clothes are heated uniformly, and the drying speed is equal. The drying speed of the clothes in each part of the wardrobe body is equal, so that the automatic control of the clothes drying wardrobe is beneficial.
Specifically, the pair of contact electrodes 6 need to be in contact with each other to realize power supply to the heating circuit, and considering that the partition plate 3 is slidably disposed between the two side walls of the cabinet 1 through the slide rail 4, the partition plate 3 is in contact with the slide rail 4 and the cabinet 1, and therefore the pair of contact electrodes 6 is disposed on a contact surface between the partition plate 3 and the slide rail 4 or the cabinet 1. The sliding rail can be specifically arranged on any part of the whole sliding rail, and can also be arranged on the side wall of the cabinet body 1 close to the side edge of the partition board 3.
In particular, it is necessary to ensure that the inside of the cabinet 1 is filled with hot air during the drying process, and because of the upward flowing property of the hot air, the heated air is firstly gathered at the upper part of the cabinet 1, which may result in an undesirable drying effect of the clothes at the lower part of the cabinet. In order to ensure that the cabinet body 1 is filled with hot air all the time in the clothes drying process, the air inlet 12 is arranged at the upper part of the cabinet body 1, and the air outlet 11 is arranged at the bottom of the cabinet body, so that the hot air is discharged after the cabinet body 1 is filled with the hot air.
In particular, it is desirable to provide the air inlet 12 at the upper portion of the side wall of the cabinet 1 because if the air inlet 12 is provided at the top of the cabinet, dust and foreign materials are liable to fall into the cabinet to contaminate the laundry. Similarly, the exhaust port 11 is provided at the bottom of the side wall.
Furthermore, the steam is evaporated during the drying process, so that the damp-heat air needs to be exhausted, and therefore, the embodiment of the present invention is provided with a fan on the exhaust port 11 and/or the intake port 12. Specifically, the fan 7 is provided at the exhaust port 11 so that the water vapor (moisture) can be efficiently exhausted out of the cabinet 1.
Furthermore, a convex part 41 is arranged on the part of the tail end of the sliding rail 4 close to the rear wall of the cabinet body, and the convex part 41 abuts against the tail end of the partition board 3 to limit the partition board 3 to slide towards the rear wall of the cabinet body 1.
This has the advantage that the position of the partition 3 can be fixed by the projection 41, and this is highly necessary. This is because the power supply of baffle 3 relies on its and slide rail or the realization of a pair of contact electrode 6 on the cabinet body 1 contact surface, if the position of baffle 3 can not be fine fixed, can lead to contact electrode 6 bad, influences the normal work of heating circuit on the baffle 3, influences the dry clothing effect.
Further, the pair of contact electrodes 6 is arranged on the contact surface of the convex part and the tail end of the separator 3, and comprises a conductor contact 61 arranged on the tail end of the separator 3 and a power supply electrode 62 arranged on the surface of the convex part, wherein the conductor contact 61 is in a convex columnar structure, and the power supply electrode 62 is in a groove structure matched with the convex columnar structure.
This is provided to ensure stable contact of the contact electrode 6. Although the contact electrode 6 can be arranged at any position of the front, middle and rear parts of the contact surface of the side edge of the partition board and the slide rail 4. However, if the contact electrode 6 is arranged at the front end of the sliding rail and is closer to the cabinet door 2, a user may be in danger of electric shock during operation. Thus eliminating the solution provided at the front end. If set up contact electrode 6 on the slide rail middle section, because slide rail 4 and the side of baffle 3 sliding friction in the plug in-process can cause wearing and tearing, will lead to the fact contact failure after the time has been long, consequently has also got rid of this kind of setting mode.
