Description

  The present invention relates to a heating cooker for baking cooked items such as fish used in general households.

  Conventionally, this type of cooking device has a door that opens and closes the entrance of the cooking chamber provided in the main body, and the main body provided below the door-side engagement portion provided at the lower portion of the door and the main-body side entrance. There is a configuration in which the door is closed by engaging the side engaging portions with each other (for example, see Patent Document 1).

  In the conventional cooking device, when the user closes the door, a main body side engaging portion made of resin or metal provided below the main body side entrance has a protruding shape provided at the lower portion of the door. The door side engaging portion is held by the biasing force of the spring, and the door is pulled into the main body side. In addition to the above configuration, the door is kept closed by providing at least one configuration that locks the door by overcoming the unevenness formed in the cooking chamber or the main body. There are also things.

By configuring the engaging portion as described above, even if the pressure in the cooking chamber rises slightly, the door opens naturally, or smoke generated in the cooking chamber during cooking is generated from the gap between the door and the main body. It was no longer leaking.
Japanese Patent No. 3183230

  However, in the conventional configuration, the configuration in which the engaging portion is sandwiched by the biasing force of the spring and the door is pulled toward the main body side needs to open and close the door against the biasing force of the spring, and the opening / closing force is hard. Therefore, a good operational feeling could not be obtained. In addition, the structure that locks the door by overcoming the unevenness provides a light feeling of operation when opening and closing because there is no spring biasing force, but a rail for smoothly guiding the saucer is provided on the upper side of the saucer In such a case, it is necessary to set the gap between the rail and the upper surface of the tray larger than the height over the unevenness. This is to prevent the door from being able to be opened and closed due to the tray hitting the rail when overcoming the uneven portion. As a result, the gap between the upper surface of the tray and the rail is increased, and the backlash of the tray is increased, so that a good operational feeling cannot be obtained when opening and closing.

  The present invention solves the above-mentioned conventional problems, and provides an easy-to-use cooking device that has a structure that prevents smoke leakage and at the same time provides a good operational feeling that is not stiff when the door is opened and closed and has little play. With the goal.

  In order to solve the conventional problems, a cooking device according to the present invention includes a cooking chamber provided in a main body, a door for opening and closing a front opening of the cooking chamber, and the door disposed in the cooking chamber. A tray that is connected to and interlocked with the rail, and a rail that guides the upper surface when the tray slides, and a concave and convex portion that engages with each other is provided below the cooking chamber and at the bottom of the door to close the door In the configuration in which the door is locked by overcoming the concavo-convex portion, the concavo-convex portion on the door side or the cooking chamber side is formed of an elastic body having a spring property.

  As a result, even when the upper surface of the tray hits the rail when the door gets over the uneven portion, the height can be absorbed by the spring property of the uneven portion, so that it is hard to open and close the door and a good operational feeling with little play is obtained. .

  The heating cooker of the present invention has a configuration that prevents smoke leakage, and at the same time, is not hard when the door is opened and closed, and provides a good operational feeling with little backlash.

  1st invention is the cooking chamber provided in the main body, the door which opens and closes the front opening part of the said cooking chamber, the saucer which is arrange | positioned in the said cooking chamber and interlock | cooperates with the said door, and the said saucer. And a rail that guides the upper surface when sliding, and a concave and convex portion that engages with each other is provided below the cooking chamber and at the lower portion of the door, and when the door is closed, the door is moved by overcoming the concave and convex portion. In the structure to be locked, the uneven portion on the door side or the cooking chamber side is formed of an elastic body having a spring property, so that the spring of the uneven portion even if the upper surface of the tray hits the rail when the door gets over the uneven portion. Since the height can be absorbed by the property, it is hard to open and close the door, and a good operational feeling with little play is obtained.

  In the second invention, in particular, since the clearance between the upper surface of the tray and the rail of the first invention is set to be substantially the same as the height over which the uneven portion is climbed, both the operating force at the time of climbing and the clearance between the upper surface of the tray and the rail Can be set to a minimum, and an operation feeling that is less stiff and less rugged can be obtained.

  In the third invention, in particular, the concavo-convex portion of the first or second invention is constituted by an elastic body whose cross-sectional concavo-convex shape extends in a direction perpendicular to the door opening / closing direction and which is bent in the direction in which the cross-sectional concavo-convex shape extends. Thus, even when the uneven portion is bent, the contact between the uneven portion on the door side and the main body side can be kept constant, and a stable operation feeling can be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

FIG. 1: shows the external view seen from the front surface of the heating cooker in the 1st Embodiment of this invention. A top heater portion 3 having an induction heating coil inside and an upper surface formed of a ceramic plate 2 is provided at the upper portion of the main body 1 forming the outer shell, and a liquid crystal type is provided at the front portion of the top heater portion 3. The operation unit 6 including the display unit 4 and the operation switch 5 is provided. The left half of the inside of the main body 1 is composed of a cooking unit 7 for grilling and cooking fish or meat, and the entrance can be opened and closed by a door 11 provided on the front surface. The right half is composed of a circuit board having many electronic components and a circuit unit 9 having a blower 8 for sending external air into the main body 1 and cooling induction heating coils and electronic components. Has been. A power switch 10 for turning on / off the main power supply of the cooking device is provided on the front surface of the circuit unit 9.

  FIG. 2 is a longitudinal sectional view of the heating cooker according to the embodiment of the present invention.

  The cooking unit 7 is provided with a cooking cabinet 12 for heating and cooking food such as fish and meat. Inside the cooking cabinet 12, a grill 13 for placing the cooking product, A tray 14 is provided on which the grill 13 is placed and slidable in the front-rear direction, and a heater 15 for heating the food. Further, the front opening 16 of the cooking cabinet 12 is configured to be opened and closed by a door 11 having a handle 17. The saucer 14 and the door 11 are connected to each other by a support bracket 20, and the saucer 14 is moved back and forth along a rail 18 for guiding the saucer 14 provided in the cooking cabinet 12 in conjunction with the opening / closing operation of the door 11. It is configured to slide. Moreover, the uneven | corrugated | grooved part 19 which mutually engages is provided in the lower part of the door 11, and the downward direction of the cooking chamber 12, and when the door 11 is closed, it has the structure which latches the door 11 by overcoming the uneven | corrugated | grooved part 19, The concavo-convex portion 19 on the cooking cabinet 12 side is made of an elastic body having a spring property such as metal or resin. In the present embodiment, the concavo-convex portion 19 has a shape in which the cross-sectional concavo-convex shape extends in a direction perpendicular to the opening / closing direction of the door 11, that is, a direction perpendicular to the drawing, so that the concavo-convex shape extends in the extending direction. It has become. Further, the clearance a formed between the upper surface of the tray 14 and the rail 18 and the climbing height b of the uneven portion 19 are set to be substantially equal. The door 11 is provided with a packing 24 made of heat-resistant rubber or the like for sealing the periphery when the front opening 16 is closed.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the user performs cooking by heating, the food is placed on the grill 13 in a state where the door 11 is opened and the tray 14 is pulled forward. Thereafter, the handle 17 is held, and the tray 11 is slid along the rail 18 by pushing the door 11 in the direction of the front opening 16 to insert the food into the cooking cabinet 12. If the door 11 is continuously pushed as it is, the uneven portion 19 below the door 11 gets over the uneven portion 19 below the cooking chamber 12 and is locked, and the packing 24 reliably seals the periphery of the front opening 16.

  By the way, in the operation | movement which closes the door 11 as mentioned above, when the uneven | corrugated | grooved part 19 of the lower part of the door 11 gets over the uneven | corrugated | grooved part 19 below the cooking chamber 12, since the door 11 and the saucer 14 are connected, the upper surface of the saucer 14 is Approach the rail 18. For this reason, it is usually impossible to get over the uneven portion 19 unless the clearance between the upper surface of the tray 14 and the rail 18 is overcome and set larger than the height. However, in the present embodiment, since the uneven portion 19 below the cooking chamber 12 is formed of an elastic body having a spring property, the uneven portion even if the upper surface of the tray 14 hits the rail 18 when the door gets over the uneven portion 19. Since the height can be absorbed by the spring property, the gap between the rail 18 and the upper surface of the tray 14 can be set small, so that a good operational feeling with little backlash when the door is opened and closed can be obtained.

  In the present embodiment, the clearance a between the upper surface of the tray 14 and the rail 18 is set to be substantially the same as the climbing height b of the concavo-convex portion 19. Therefore, it is possible to achieve both a light operation feeling when getting over and an operation feeling with little backlash.

  Further, in the present embodiment, the uneven portion 19 is formed of an elastic body having a cross-sectional uneven shape extending in a direction perpendicular to the opening / closing direction of the door 11 and being bent in a direction in which the cross-sectional uneven shape extends, and therefore the door 11 is opened / closed. When the uneven portion 19 is bent, the angle of the main body 1 side with respect to the door 11 side of the uneven portion 19 does not change because there is no deflection in the opening / closing direction of the door 11. Therefore, it is possible to obtain a stable operation feeling with little variation due to the airframe.

  When the user starts cooking while the door 11 is closed by the above operation, the food is heated and smoke is generated. Normally, smoke is exhausted by the exhaust pipe provided at the rear of the cooking chamber, but when the gap between the door 11 and the cooking chamber 12 is wide, smoke leaks from the door portion. However, according to this structure, since the sealing of the door 11 and the cooking chamber 12 is maintained by locking the door 11 by overcoming the uneven portion 19, no smoke leaks from the door portion. .

  In addition, in this Embodiment, although it was set as the structure which gave the uneven | corrugated | grooved part 19 by the side of the cooking chamber 12 with springiness, the uneven | corrugated | grooved part 19 provided in the lower part side of the door 11 was given springiness. The same effect can be obtained even if it is deflected.

  As described above, the cooking device according to the present invention improves the operational feeling when the door is closed, and slides along the rail in conjunction with the door that opens and closes the opening of the warehouse. It can be applied to an apparatus having a saucer.
