BACKGROUND OF THE INVENTION
The present invention relates to an electric lift hanging cabinet that moves the cabinet up and down by an electric lifting mechanism to effectively use the space above the building, and in particular, a tableware dryer, a draining shelf, a storage, and the like incorporated in a ceiling unit of a system kitchen. In addition, the present invention relates to an electric lifting / lowering cabinet that can easily and safely perform the lifting and lowering operation of the cabinet.
[0002]
[Prior art]
For example, in an electric lifting cabinet that is applied to a system kitchen as a tableware dryer, etc., a switch for power operation such as a heat source for drying or a drive unit for supplying hot air, moving, stopping, direction selection, etc. An operation control operation unit is required.
[0003]
In this case, the cabinet is placed above the kitchen table and sink, and various tools, equipment, ingredients are placed under the cabinet, and water is used. Are often provided with switches and an operation unit (see, for example, Patent Document 1).
[0004]
However, since the cabinet itself is a mobile device, switches that move together with the cabinet are generally difficult to operate, and in addition to causing malfunctions themselves, users can operate with one hand for efficiency. It is normal, and causes of erroneous operations are included depending on the location and arrangement of switches.
[0005]
In addition, in the case of an electric lifting cabinet, the cabinet is lifted up with the tableware protruding from the tableware bowl, interfering with the automatic opening / closing door, etc. It is considered that it is not preferable to move up and down the entire stroke. For this reason, it is common to employ an operation mechanism in which the lifting and lowering operation of the cabinet or the like is performed only while operating the lifting lever or the like, and the operation stops when the hand is released.
[0006]
[Patent Document 1]
Japanese Patent Laid-Open No. 2003-9962
[Problems to be solved by the invention]
However, in the conventional apparatus that operates only the lifting lever described above, convenience for the lifting operation cannot be obtained, and it is difficult to obtain a speedy lifting operation.
[0008]
Further, in the known technique described in Patent Document 1, when the switches are arranged on the surface of a relatively short handle and the user operates with one hand, the finger of the hand holding the handle is parallel to the handle. It is designed to operate in the direction.
[0009]
In this case, it is only about the thumb that can be operated in the direction parallel to the handle while the handle is held, and various switch operations are difficult, lacking in operability, and easily causing an erroneous operation.
[0010]
On the other hand, when lowering the cabinet, there is a possibility that various articles placed on a lower cooking table or the like come into contact with each other and the articles are damaged. Conventional handles are relatively short in the left-right direction, and even if the handle passes, there is a high possibility that the cabinet will come into contact with an article in the vicinity thereof.
[0011]
Moreover, when applying to a tableware dryer, the structure which hold | maintains a water tray in a cabinet so that attachment or detachment is possible is needed. Since this water tray is taken in and out of the cabinet, if the switch is placed close to the switches, the switches may be splashed with water.
[0012]
