Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention provides a method for solving the problem of 1'=7+l! u! This invention relates to an electric component mounting structure for an ice maker, which is designed to melt the electric components from the atmosphere and prevent functional deterioration of the electric components due to rusting.

[-Prior art]

In general, an ice maker has an ice maker inside a cabinet surrounded by an insulating material, an ice maker cooled by a refrigeration device, a water container that stores water for ice making supplied from outside, and an ice maker that stores ice cubes that are cooled by a refrigeration device. The system is equipped with a water circulation pump that flows water down onto the ice-making plate, detects the temperature of the ice-making plate, and performs ice-making or ice-removal operations electrically.

A thermostat etc. is installed for control.

However, the atmosphere in this ice-making chamber becomes extremely high in temperature due to the above-mentioned circulation of water, etc., which corrodes the motor section of the water circulation pump, the movable section of the thermostat, etc., and the ice-making chamber becomes unable to perform its functions satisfactorily.

Therefore, in order to improve these problems, conventionally, individual electrical components were covered with a cover or the like. As a result, some effects were observed, but since the environment was in a high humidity atmosphere, a sufficient improvement effect could not be obtained.

[Purpose of the invention]

An object of the present invention is to connect the -+Tn of the cover covering the electrical equipment with the outside air, thereby making the atmosphere inside the cupboard, that is, around the electrical equipment the same as the outside air, and exposing the electrical equipment to a high-humidity atmosphere. Therefore, the objective is to prevent functional deterioration due to speech, etc.

[Summary of the invention]

That is, 1 the present invention provides ice making ζC (3a
), water circulation pump (9), and other items - Mosta 1 -
(13) For ice making machines that have electrical components such as
Turn it over, fix it to the inner box with a loa, etc., and
The end face of the box-shaped cover (JO) with an open surface is brought into contact with the first insulation phase (14a) attached to the upper panel (14), and then the opening of the cover (]0) of the upper panel This is an electrical component mounting structure for an ice maker characterized by having a plurality of ventilation holes drilled on the top and 1 sides of the opposing parts.

[Embodiments of the invention]

An m-embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

] is the ice maker main body', 2 is the main body] is a heat insulating material attached to the outer circumferential inner surface of the ice maker body. Separated by 4. Further, the inside 3 of the machine has an ice making chamber 3a in the upper part and a water storage chamber 3b in the lower part. The machine room 4 has a refrigeration cycle configuration 1fj≦products such as a compressor and a condenser, and also stores control parts (not shown) for controlling ice making, ice removal, and ice removal.

Further, the ice making compartment 3a includes an ice making machine 5 which is cooled by a refrigeration cycle and makes ice little by little by letting water flow down here.
A water storage tank 6 that stores one batch of ice-making water supplied from the outside.
Then, after receiving the water that flowed down the ice-making plate 5 and did not freeze,
It has a gutter 7 that returns the water to the water tank 6 again. In addition, gutter 7 and water tank 6
The two are connected by a communicating pipe 8 at a position that does not interfere with the falling ice blocks. 9 is a water circulation pump having a motor 9a at the top and a casing 9b at the bottom. The motor 9a and casing 9b of the circulation pump 9 are connected by a tubular shaft cover 90. Blades (not shown) are built inside the casing 9b, and the rotating shaft of the five blades and the rotating shaft of the motor 9a are connected inside the axial force bar 90. The motor 9a is fixed to the inner box with screws 9e etc. according to the morph mounting j (l≦ifA' 9d. Furthermore, the motor 9a is fixed to the inner box with a synthetic resin '
Cover with a cover 10 made of S-. At this time cover 10
is box-shaped and has a flank 10a except for the - face. Fix the flank lOa tightly to the inner box side with screws ]01]. In addition, at this time, one surface (hand riif side) of <-10 is set as the open surface 10d.

Furthermore, the force at the point where the shaft cover 90 penetrates) < -IO
A notch 1'OC is provided in the shaft cover 9, and the notch 10C is sealed with a grommet provided on the shaft cover 9. In addition, in order to thermally isolate the inside of the cover 10 (Fil) from the surroundings of the cover 10 (i.e., the ice making compartment), a flexible heat insulating material 4A' such as polyethylene foam is used on the inward side of the cup <-10. Here, the heat insulating material 12 is made slightly longer than the length of the cover lO (2t+H).
τIS), when fixing the cover 10 to the inner box,
The second protruding dimension portion 12a is in close contact with the inner box, that is,
Seal at this point.

To mount the thermostat 13 and the like inside the cover 10, a concave groove 10e is formed in the flange of the cover 1O for the capillary tube 13a of the thermostat 3, and the capillary tube 13 is brought out of the cover 10 from here. A heat insulating material 12a is also pasted here, and when the capillary tube 13 comes out from the concave groove 10e, it seals the groove 10e.

There is an upper panel 14 in front of the cover, and a heat insulating material 14a is pasted on the back side of the upper panel 4.The heat insulating material 14a and the periphery of the opening 10d of the cover 10 are in close contact with each other. The heat insulating material 14a is not required in the upper panel 14 at the location corresponding to the opening 10d, and the air hole 14 is provided at this location.
Leave b open.

That is, the inside of the cover 10 is isolated from the ice-making compartment 3a, which is at a high temperature, and the outside air that has entered through the air hole 14b of the upper panel 14 freely enters and exits the inside of the cover 10 from the open surface 14d of the cover, so that the pump motor 9 and The thermostat 13 and the like are not exposed to a high-temperature atmosphere, and therefore it is possible to prevent functional deterioration of the three products due to rusting or the like.

〔Effect of the invention〕

It is installed inside the ice maker as described in detail below.

In the box-shaped cover 10, which is mainly used for electric Her, The edge of the cover 10 is placed in contact with the insulation IrA14a provided on the upper panel, and the opening of the cover 10 is connected to the outside air, so that the inside of the cover 10 always has the same atmosphere as the outside air, which is different from the conventional method. Cover as in ] 0 inside H
yl(force)<-10 since it does not become highly humid, it has a rust-preventing effect on internal electrical parts, etc., and has a great practical effect.

In addition, to prevent rust on electrical parts, etc., it may be possible to install these electrical parts in a non-contact manner, but in this case, the structure of the cabinet may be complicated, or
There is a problem with the knob where the electrical component passes through the cap.
There are drawbacks such as At.
