Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric lifting / lowering cabinet that can be moved up and down by storing tableware, such as a tableware dryer or a draining shelf. It relates to a hanging cupboard.
[0002]
[Prior art]
In this kind of electric lifting shelf, a large amount of tableware is stored in the tableware supported by the cabinet and moves up and down. Therefore, load resistance, vibration resistance, etc. are applied to the wall for cabinet construction that supports the tableware. On the other hand, a certain level of structural strength is required. On the other hand, in order to improve efficiency by reducing the weight of the cabinet itself, a request for reducing the wall thickness is also received.
[0003]
Under such many requests, conventionally, a proposal for strengthening the peripheral wall structure of the cabinet has been made (see, for example, Patent Document 1). In this proposal, structural reinforcement is achieved by sandwiching a relatively thin cabinet-constituting wall from the end side or the periphery with a reinforcing plate or the like.

[Problems to be solved by the invention]
However, in the above-described conventional technology, the number of component parts of the cabinet is increased, the configuration becomes complicated, the production time is increased, and the cost is increased. While the location of noise generation increases, it is not always effective for improving the strength of the cabinet wall itself.
[0006]
Moreover, when there are many connection places, the site | part which mounts and supports a tableware bowl and a shelf board reduces, and the mounting state of a tableware bowl and a shelf board may become unstable. Furthermore, there is a possibility that the strengthened portions are unevenly distributed, and the load is concentrated on a partial low strength portion to cause a problem in the overall strength. Moreover, in the conventional structure, when the mounting part shape and material of the tableware and shelf provided in a cabinet change, it may become impossible to support the whole area, and it may be difficult to respond.
[0007]
The present invention has been made in view of such circumstances, and the strength inside the cabinet can be increased overall and uniformly at a low cost with a relatively simple configuration. In particular, the back plate is made thinner and lighter. The purpose of this invention is to provide an electric hoisting cabinet that can prevent the generation of vibration and accompanying noise, and can respond to changes in the shape and material of the tableware and shelf to be supported. To do.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a tableware can be detachably mounted inside a front opening cabinet having both side plates and a back plate suspended from an upper part of a building by an electric lifting mechanism. In the electric lifting / lowering cabinet that can be placed, an electric lifting / lowering cabinet that is provided with ribs for placing tableware on the back plate of the cabinet that moves up and down is provided.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of an electric lift hanging cabinet according to the present invention will be described with reference to FIGS. In addition, this embodiment demonstrates the case where it applies as a ceiling installation type raising / lowering tableware dryer in a system kitchen as an example. However, the present invention can be applied to various electric hanging cabinets such as a drying cabinet and a draining shelf.
[0010]
FIG. 1 is a perspective view showing the overall configuration of the elevating tableware dryer according to the present embodiment. FIG. 2 is a side sectional view, and FIG. 3 is a front view showing a partial section with the front face omitted.
[0011]
As shown in FIGS. 1 and 2, the elevating tableware dryer of the present embodiment basically includes an outer box 1 installed on or near the ceiling, and a cabinet provided in the outer box 1 so as to be movable up and down. The door 3 is provided in front of the outer box 1.
[0012]
The outer box 1 is composed of a top plate 1a, a front plate 1b, both side plates 1c, a back plate 1d, and the like, and the lower end is entirely open and portions other than the front front plate 1b are open. Long side guide rails 4 are provided on the inner surfaces of both side plates 1c of the outer box 1 to guide the inner box 2 up and down, and a frame 5 for supporting parts is provided on the inner surface (lower surface) of the top plate 1a. ing. The door 3 is connected to the front hanging plate 1b of the outer box 1 via hinges 6 provided at, for example, three locations on the upper edge, thereby the door 3 has the lower edge in the front-rear direction with the upper edge as a fulcrum. It is the structure which can rotate.
[0013]
The inner box 2 constitutes a tableware dryer main body, and is formed in a shape that the front surface is opened by an upper plate 2a, a lower plate 2b, both side plates 2c and a back plate 2d, and two upper and lower tableware bowls 7a and 7b are provided inside. It is set as the structure which can be mounted so that attachment or detachment is possible. The dimension between the outer surfaces of the two side plates 2c of the inner box 2 is set slightly smaller than the dimension between the inner surfaces of the both side plates 1c of the outer box 1, and the vertically narrow lateral sides between the side plates 1c and 2c are respectively set. A space 8 is formed. In addition, the height of the inner box 2 is sufficiently smaller than the outer box 1, and an equipment space is formed above the inner box 2.
[0014]
The inner bottom portion of the inner box 2 is configured as an inclined drain receiving water collecting portion 22, and the drain collected by the water collecting portion 22 can be attached to and detached from the front side of the bottom plate 2 b through the drain port 23. It is stored in the provided water tray 24.
[0015]
And the lower tableware bowl 7b is a thing of the structure which can lean and accommodate a comparatively large tableware, and has comprised the fence shape with a large up-down dimension. The lower tableware bowl 7b is stably placed on the water collecting portion 22 which is the inner bottom of the inner box 2, and the lower tableware bowl 7b is placed against the side plates 2c and the back plate 2d of the inner box 2. The weight only works as a whole.
[0016]
On the other hand, the upper table bowl 7a stores relatively small tableware, has a flat fence-like shape, and is located at a substantially intermediate height position between the side plates 2c and the back plate 2d of the inner box 2. It is supposed to be placed. Therefore, the upper tableware bowl 7a can apply a bending load to the both side plates 2c and the back plate 2d of the inner box 2, and can also apply the same load when moving up and down. Therefore, the side plates 2c and the back plate 2d of the inner box 2 are important mounts for reducing the thickness, weight, strength, and the like of the upper tableware bowl 7a.
[0017]
In this embodiment, the entire front end edge of the upper tableware bowl 7a is placed on a horizontally long support rod 36 laid between the front side opposing portions of the side plates 2c of the inner box 2, and the upper tableware bowl 7a is placed. The load on the front edge side of 7a is uniformly supported by the left and right side plates 2c.
[0018]
Further, the rear end edge of the upper tableware bowl 7a is uniformly supported by ribs 37 integrally formed on the inner surface side of the back plate 2d in the left-right direction. The rib 37 is formed by bending a back plate 2d made of a high-strength lightweight material such as a thin metal or resin, for example, into a V-shaped cross section that bulges to the inner surface side, as shown in FIG. Although not shown, the back plate 2d is formed of a solid projection having the same outer shape as described above.
[0019]
The surface of the rib 37 protruding to the inner surface side of the inner box 2 is flat as a whole, and the support side of the upper tableware bowl 7a is placed on the whole and uniformly so as to support the load evenly. It has become.
[0020]
Accordingly, the back plate 2d of the inner box 2 having the rib 37 having such a shape is subjected to a load equally over the entire left and right direction, while the back plate 2d has a left and right direction that is the longitudinal direction of the rib 37. The rigidity along the line is evenly increased. If the vertical ribs are formed below the ribs 37 so as to protrude inward at a predetermined interval, although not shown, the rigidity is further increased.
[0021]
According to such a configuration, the load on the rear edge of the upper tableware bowl 7a shown in the figure can be supported uniformly over the entire left and right direction of the back plate 2d via the rib 37, and by the support rod 36 provided in the front. Since the load on the front edge side of the tableware bowl 7a can be evenly supported, it is possible to place almost the entire area of the upper tableware bowl 7a as an equal load, thereby stabilizing the upper tableware bowl 7a. It can be placed.
[0022]
Further, since the support rod 36 and the rib 37 are provided, it is not necessary to provide a special mounting member, so that the number of parts can be reduced and the cost can be suppressed.
[0023]
Although not shown, by providing the mounting portion integrally with the back plate 2d, the strength of the back plate 2d can be increased, and the vibration of the back plate 2d that may occur during the raising and lowering and the vibration sound accompanying the vibration Can be prevented.
[0024]
In addition, when placing the tableware bowl 7a or a shelf board (not shown), even if the placement part shape, material, etc. of the tableware bowl 7a change, the placement part is arranged in front of and behind the inner box 2d. In this case, since it extends over substantially the entire region in the left-right direction, it is easy to support.
[0025]
Furthermore, since the strength of the inner box 2d can be increased by forming the rib 37, the thickness of the back plate 2d can be reduced.
[0026]
Moreover, since it is not necessary to provide a mounting member separately, the number of parts can be reduced and the cost can be reduced.
[0027]
By providing the rib 37 as a mounting portion integrally with the back plate 2d, the strength of the back plate 2d can be increased, and vibration of the back plate 2d that may be generated during raising and lowering and generation of vibration sound accompanying the vibration are generated. Can also be prevented.
[0028]
