Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a power switch in a cooling storage such as an automatic ice maker. 2. Description of the Related Art In a conventional automatic ice maker, as shown in FIG. 4, when a lower front panel 2 covering the front of a machine room 1 is removed, a control box 3 and a condenser are provided on the front. 4 is installed, and a switching knob 4 of a power switch fixed in the control box 3 is
It was configured to protrude forward from a window 5 formed in the control box 3. In this case, in order to open and close the power switch by operating the switching knob 4 up and down, it is necessary to remove the lower front panel 2, which is troublesome and arranged close to the control box 3. It is necessary to take care that the hand does not touch the fin end face of the condenser 4 which has been operated, and since the power switch in the control box 3 is provided at a low position near the floor, the operation of the switching knob 4 is performed. Not only is the property relatively poor, but also floor cleaning water, etc., is poured into the machine room 1 through the intake port 6 formed in the lower front panel 2 and enters the power switch through the window 5 of the control box 3. There was a risk of doing so. In order to prevent such intrusion of water into the power switch, as shown in FIG. 5, a switch cover 8 is fitted inside the control box cover 7, and when the control box cover 7 is mounted, the switch cover 8 is attached. Is the switching knob 4 in the power switch 9
Although it is conceivable to completely cover the periphery, there is a problem that assembling of the control box cover 7 is deteriorated as much as the switch cover 8 needs to be attached, and that the switch cover 8 is easily deteriorated with time. Was. An object of the present invention is to improve the operability of a power switch in a cooling storage and increase the waterproofness of the power switch. [0006] Therefore, in the power switch mounting structure according to the present invention, a box-shaped cover is arranged inside the upper front panel in the cooling storage box.
Power switch body is fixed to the upper surface of the box-shaped cover, the upper
The bottom of the power switch body and the bottom of the box-shaped cover
A gap is formed between the power switch body and the switching knob of the power switch protruding below the upper front panel from the power switch main body, and the upper edge of the closed door in the cooling storage box substantially covers the front of the switching knob. Have been. That is, the power switch body is fixed to the upper surface of a box-shaped cover arranged inside the upper front panel.
The bottom of the power switch body and the bottom of the box-shaped cover
A gap is formed between the power switch body and the box-shaped cover.
Higher than the bottom of the upper front panel
Attached to the inner and outer surfaces of the upper front panel
Make sure that condensed water, etc.
The switching knob of the power switch protrudes from the power switch main body below the upper front panel, and the switching knob is disposed relatively high from the floor where the cooling storage is installed. Therefore, the operation of the switching knob becomes relatively easy, and it is possible to completely eliminate the possibility that cleaning water or the like may enter the power switch. In addition, the upper edge of the closed door in the cooling storage is located in front of the switching knob. When the door is open, the switching knob can be operated from the front side to open and close the power switch, but when the door is closed, the operation of the switching knob becomes impossible. Hereinafter, embodiments of the present invention will be described. 1 to 3, an upper front panel 11 of a cooling storage 10 such as an automatic ice maker has a substantially U-shaped vertical section, and a box-shaped cover 13 that opens downward and forward is provided on a bottom surface 12 thereof. The cover 13 is fixed by a screw 15 passing through the cut groove 14 of the bottom surface 12 from below.
A heat insulating material 16 is attached to the outer surface of. In the cover 13, a power switch body 18 is attached to the top surface of the cover 13 by screws 17, and a gap is provided between the bottom surface 12 of the upper front panel 11 and the lower end of the power switch body 18. 19 are formed. Further, a switching knob 20 of the power switch, which extends downward from the power switch body 18, projects further downward through an opening 21 formed in the bottom surface 12 of the upper front panel 11. A pocket 22 which is integrally formed with the opening 12 and opens forward.
However, the switching knob 20 is covered at appropriate intervals on the rear side, both sides, and the lower side, and a finger is inserted into the pocket 22 from the front, so that the switching knob 20 can be operated left and right. When the door 23 of the storage 10 is closed from the front side, the upper end edge of the door 23 substantially covers the front of the pocket 22. In the above apparatus, the power switch body 18
Is mounted on the upper front panel 11 which is considerably higher than the floor, the operability and safety of the switching knob 20 projecting downward from the power switch main body 18 are high, while the power switch main body 18 is provided with the cover 13 and the heat insulating material 16.
To prevent dew condensation from occurring on the surface thereof, the switching knob 20 of the power switch body 18 is directed downward, and the power switch body 18 is Since it is mounted at a position higher than the bottom surface 12 of the panel 11, it is possible to reliably prevent dew condensation and the like adhering to the inner and outer surfaces of the upper front panel 11 from sneaking into the power switch main body 18, as well as to the floor surface. No cleaning water or the like is applied to the power switch main body 18 at all, and the waterproofness of the power switch is improved, so that the function of the power switch can be favorably maintained for a long time. In addition, by opening the door 23 of the cooling storage box 10, it is possible to open and close the power switch by operating the switching knob 20 from the front side. Since the switching knob 20 is housed in the pocket 22 of the upper front panel bottom surface 12, when operating the switching knob 20, the hand can be applied to the pocket 22 or the depth of the pocket 22 can easily insert the finger. Since the restriction can be performed, there is an advantage that the operation of the switching knob 20 by the finger is relatively easy. Further, when the door 23 of the cooling storage 10 is closed from the front side, the upper end edge of the door 23 almost covers the front of the pocket 22 and the switching knob 20 cannot be operated. Erroneous operation of the switching knob 20 can be completely prevented. In particular, when the door 23 is opened sideways, the hinge of the door 23 is connected to the right side of the cooling storage 10 where the power switch body 18 is installed (the door in FIG. 1). (Left side of 23), it is difficult to operate the switching knob 20 unless the door 23 is opened widely, so that erroneous operation of the switching knob 20 can be prevented, and safety can be further improved. Needless to say, the present invention can be similarly applied to the case where the door 23 is set forward. On the other hand, even when each of the doors 23 is open, since the switching knob 20 is located behind the surface of the upper front panel 11, the hand contacts the surface of the upper front panel 11. It is also possible to easily prevent the switching knob 20 from being erroneously operated due to the above. In the switch mounting structure according to the present invention, the power switch main body is fixed to the upper surface of the box-shaped cover arranged inside the upper front panel, and the power switch is mounted .
The switch body is inside the box-shaped cover and the bottom of the upper front panel
Higher than the upper freon
Condensation on the inner and outer surfaces of the power panel
I can certainly prevent it from going around my body,
The power switch body can be made more waterproof,
In addition, since the switching knob of the power switch protrudes from the power switch body below the upper front panel, and the switching knob is arranged higher than the floor, the operation of the switching knob becomes relatively easy, and The function of the power switch can be maintained well over a long period of time by completely eliminating the possibility that cleaning water or the like may enter the power switch, and the upper edge of the closed door in the cooling storage is located in front of the switching knob. Because the door is almost covered, the power switch can be easily opened and closed by operating the switching knob from the front side by opening the door, while the switching knob cannot be operated when the door is closed, Erroneous operation of the knob can be completely prevented.
