DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter mounting structure for a showcase with a built-in refrigerator.

[0002]

2. Description of the Related Art First, a filter mounting structure of a conventional refrigerator-incorporated showcase is shown in FIG. 3, taking a flat open showcase as an example. In the figure, 1 is a case body of a flat open showcase, 2 is a base with open front and rear surfaces, 3 is a condensing unit of a refrigerator housed inside the base 2, and 4 is a condensing unit of the condensing unit 3. An air purifying filter that covers the front surface (air suction side) of the vessel 3a is a kick plate (a grill on the air suction side that also serves as a decorative plate) attached to the front surface of the base 2. Here, the filter 4 is mounted on the front surface of the condenser 3 a via the holding plate 6 and the set screw 7, and the kick plate 5 is fixed to the front surface of the base 2 via the set screw 8.

[0003]

The above-mentioned filter is provided to prevent the condenser of the condensing unit from being clogged with dust inside the store during operation of the refrigerator. The machine stops abnormally and causes a failure. Therefore, it is necessary to remove the filter from the showcase and clean it once or twice a week as a maintenance work.

In this case, in the conventional filter mounting structure shown in FIG. 3, to remove the filter from the showcase for cleaning, first loosen the set screw 8 using a screwdriver, and then remove the kick plate 5. removal,
Further, a troublesome work such as removing the filter 4 after loosening the set screw 7 inside the base is forced. Moreover,
Since the filter 8 is mounted at a position close to the floor, this work is extremely troublesome, such as the work must be performed with the body bent, and therefore there is a strong demand for an improvement measure.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to solve the above-mentioned problems, so that even an unskilled person can attach and remove a filter by one-touch operation without using any tool such as a screwdriver. Another object of the present invention is to provide a filter mounting structure for a refrigerator-incorporated showcase that can be easily operated by using a filter.

[0006]

In order to achieve the above object, a filter mounting structure according to the present invention is configured such that a filter is detachably mounted on a back surface of an openable / closable kick plate which covers a front surface of a base of a case body. It shall be. Further, the above configuration can be implemented with the following specific structure.

(1) A pair of left and right rail-shaped support guides are provided on the rear surface of the kick plate so that the filter can be fitted out so as to be drawn out and supported. (2) The open / close kick plate is attached to the front surface of the base of the case body via the hinge at the lower end side and support means for supporting the kick plate in the open position in the forwardly inclined position, and a magnet provided on the base side. It is installed so as to be sucked and held at the closed position via.

[0008]

According to the above construction, the filter fitted into the support guide on the back side can be freely released only by pulling the kick plate installed on the front surface of the base of the case body toward the front and opening it in the forwardly inclined posture. Can be taken out or inserted. Moreover, since the kick plate is not screwed to the base and is held in the closed position via the attraction magnet, use of a tool such as a screwdriver for opening and closing the kick plate is unnecessary.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In the drawings of the embodiment, the same members corresponding to those in FIG. 1 and 2, the filter 4 is fitted in a fixed position by being fitted from above into a pair of left and right rail-shaped support guides (U-shaped cross section) 9 attached to the back side of the kick plate 5. The kick plate 5 is provided with a handle 10 at the upper front part, the lower end side is pivotally supported on the front surface of the base 2 via a hinge 11 so as to be openable, and the attraction magnet 1 provided on the base side.
2, the suction is held at the closed position indicated by the solid line. further,
A pull-out arm 13 is provided to support the kick plate 5 in the open position (indicated by a dashed line) in a forwardly inclined posture. For example, as shown in the drawing, the drawing arm 13 fits a long groove 13a extending in the longitudinal direction of the arm with a pin 14 attached to the base side to regulate the forward tilt angle at the open position. Although not shown, the base 2 in FIG. 1 has a built-in condensing unit as in FIG.

With this configuration, when removing the filter 4 from the showcase for cleaning, the user grips the handle 10 to open the kick plate 5 forward. In this open position, the kick plate 5 is inclined forward with the hinge 11 as a fulcrum, so that the operator can directly access the filter 4 fitted and supported by the support guide 9 on the back side of the kick plate 9 from above, and from there. The filter 4 can be easily pulled out. When the kick plate 9 is pushed in from the open position, the kick plate 9 is attracted to the closed position by the magnet 12. In order to mount the filter 4 after cleaning, the kick plate 9 is opened as described above,
It can be easily fitted between the left and right support guides 9 and set in place.

[0011]

As described above, according to the structure of the present invention, the following effects can be obtained. (1) The filter can be removed and attached with almost one-touch operation without using any tool such as a screwdriver.
Therefore, even a person unfamiliar with the handling of the tool can easily handle the tool, which is convenient.

(2) Since the filter can be attached and detached in a short period of time, the filter can be removed from the showcase and cleaned even during business hours of the store with little hindrance to customers. (3) The user can easily perform the cleaning work of the filter without trouble because the operation of attaching and detaching the filter is simplified, and as a result, trouble such as abnormal stop of the refrigerator or failure due to clogging of the filter occurs. Can be prevented beforehand.
