Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an improvement of an ice-making detector in an automatic ice-making device.

[Technical background of the invention and its problems]

In general, automatic ice making devices automatically supply water to the ice tray, and the temperature at which ice making is completed (for example -
10℃) is detected by the ice-making detector installed on the back of the ice-making tray, and based on this ice-making detection, the ice-making tray is rotated and twisted to release the ice from the ice-making tray, and then the ice-making tray is rotated. Ice is made by repeating the cycle of water supply, ice making, and ice removal.

Now, conventionally, the ice making detector that detects ice making is the first one.
The configuration is as shown in Figures a and b. That is, this ice-making detector includes a thermoswitch (e.g., a thermal reed switch) 2 whose contacts operate at a temperature at which the water supplied to the ice-making tray turns into ice, and a thermal A heating element (heater) 3 is provided to raise the temperature of the reed switch 2 and return to contact before the supply of water to the ice tray is completed, and the switch 2 and heater 3 are molded and fixed. ing.

Here, the thermal reed switch 2 and the heater 3 are connected to one end by soldering lead wires 4 and 5, and the vicinity of the connecting portions 6 and 7 are bent and inserted into the case 1. Therefore, when these switch 2 and heater 3 are inserted into case 1 and their connecting parts 6 and 7 face each other, there is a possibility that these connecting parts 6 and 7 will come into contact with each other. If they come into contact with each other, the above-mentioned water supply-ice-making-ice-removal cycle cannot be performed, and there is a possibility that ice making will not be possible.

[Purpose of invention]

This invention was made based on the above circumstances,
The object is to provide an ice-making detector for an automatic ice-making device in which the connecting portion between a thermoswitch and its lead wire and the connecting portion between a heating element and its lead wire cannot come into contact with each other.

[Summary of the idea]

This invention automatically supplies water to the ice tray to make ice.
After that, ice is removed and water is supplied again to make ice.A pair of recesses is provided at one closed end of the case provided on the back of the ice tray, and each recess is filled with ice. An ice-making detector in an automatic ice-making device that inserts and supports a thermoswitch that detects a thermoswitch and a bent part of its lead wire, and a heating element that returns the contact of the thermoswitch and a bent part of its lead wire. be.

[Example of idea]

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 to 4 a and b. Fig. 2 is a plan view of the automatic ice making device according to the present invention;
The figure is a sectional view of the device. In FIGS. 2 and 3, reference numeral 10 denotes the body of the automatic ice making apparatus, and a thermo-driving circuit is housed inside this body. This thermo drive circuit has the function of detecting the temperature at which ice is made by the thermo switch P, and performing ice removal and water supply operations based on this detection, and the rotation shaft 11 of the drive motor protrudes. A support frame 12 is attached to one side of the body 10 from which the rotating shaft 11 protrudes. A support shaft 13 is provided on the support frame 12 at a position facing the rotation shaft 11, and an ice tray 14 is constructed between the rotation shaft 11 and the support shaft 13. That is, the ice tray 14 has supports 15 and 1 each having an L-shaped cross section at both ends in the longitudinal direction.
6 is attached, one support 15 is connected to the rotating shaft 11, and the other support 16 is pivotally connected to the support shaft 13 and supported. This ice tray 1
4 has two ice-making recesses 17 in its longitudinal direction, and a water guide groove 18 is provided between these ice-making recesses 17.
is provided.

Furthermore, the ice-making recess 1 on the back surface of the ice-making tray 14
An ice-making detector 20 supported by a column (not shown) is installed between the ice-making detectors 7 . This ice-making detector 20 detects the temperature at which the water supplied to the ice-making recess 17 turns into ice (for example, -10 DEG C.), and its construction is as shown in FIGS. 4a and 4b. 2
1 is a detection body case, and this detection body case 2
1 has a pair of recesses 22, 2 on the closed end side.
3 is provided. These recesses 22 and 23 contain a thermal reed switch P and its lead wires.
A bent part 24 that is bent into a U-shape near the connection part where the PL is soldered, for example, and a heating element (heater)
A bent portion 25, which is formed by bending the H and its lead wire HL into a U-shape near a soldered connection portion, is inserted to support them. The depth of these recesses 22 and 23 is such that the bending part between the thermal reed switch P and the lead wire PL, and the bending part between the heater H and the lead wire HL are the same as the depth of the recess 22 and 23.
By being inserted into 23, the portions not covered with insulation do not come into contact with each other. Moreover, the shapes of these recesses 22 and 23 are as follows:
As shown in FIG. 4b, the bent portions 24 and 25 are shaped like ellipses so that they can be easily inserted and positioned within the detector case 21. The heater H is used to raise the temperature of the thermal reed switch P to restore contact before the thermal reed switch P operates to remove ice and water is supplied again. It is.

This ice-making detector 20 has recesses 22 and 2.
3. Thermal lead switch P and lead wire PL
A bent portion 24 between the heater H and the lead wire HL, and a bent portion 25 between the heater H and the lead wire HL are inserted, and the detector case 21 is further filled with a molding material 26 to form a molded structure.

In this way, in this detector, a pair of recesses 22 and 23 are provided at one end of the detector case 21, and the bent portions of the thermal reed switch P and its lead wire PL and the heater H are connected to these recesses 22 and 23. Since the bent parts with the lead wire HL are inserted, even if these bent parts 24 and 25 (connecting parts), that is, the parts without insulation coating, are facing each other or close to each other, there is no possibility of contact. There is no fear that it will. Further, since the thermal reed switch P and the lead wire PL and the heater H and the lead wire HL are positioned by the recesses 22 and 23, there is no possibility that these will move and the bent parts 24 and 25 will come into contact with each other. Therefore, the operation of the water supply-ice-making-ice removal cycle is not affected.

It should be noted that it may be inserted into any of the recesses 22, 23, such as the bent portion between the thermal lead switch P and the lead wire PL, or the bent portion between the heater H and the lead wire HL. .

[Effect of idea]

According to the present invention, at one closed end of the case,
A pair of recesses are provided that are sufficiently deeper than the lengths of the thermoswitch and its lead wires, the heating element and its lead wires, and the bent portions. And since the bent part of the heating element and its lead wire is inserted and supported, the connection part of the thermoswitch and its lead wire cannot come into contact with the connection part of the heating element and its lead wire. An ice-making detector in an automatic ice-making device can be provided.
