Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a refrigerator-freezer having a heat-sensitive device for detecting the end of defrosting.

BACKGROUND ART In general, a refrigerator-freezer is as shown in FIGS. 4 and 5. In other words, 1 is the refrigerator-freezer body, 2, 3
are the doors of the freezer compartment 4 and the refrigerator compartment 5 provided in the refrigerator body 1. Reference numeral 6 denotes a partition wall provided in the refrigerator-freezer main body 1 and integrally formed with an inner box that partitions the freezer compartment 4 and the refrigerator compartment 5. 7 is a cooler installed on the back wall of the freezer compartment 4 via a partition wall 8;
It is connected to a condenser and a capillary tube (not shown) to constitute a refrigeration device. 10 is a suction port 10a, 10 at one end.
b is connected to the freezer compartment 4 and the refrigerator compartment 5, and the discharge port 10c at the other end is connected to the intake side of the cooler 7, and is provided in the partition wall 6. , 12 are combined. 13
A fan motor disposed on the discharge side of the cooler 7 exchanges heat with the cooler 7, and the cold air is sent from the outlet 14 to the freezer compartment 4.
It is also supplied to the refrigerator compartment 5 from other outlets. Reference numeral 16 denotes a defrosting water receptacle, which supplies water to the cooler 7 through an inner box hole 18 formed in the upper inner part of the partition wall 6 of the inner box 17.
Water defrosted by a defrosting heater 19 is discharged to the outside of the main body via a hose 20. 2
1 is a box-shaped rib 2 of the defrosting water receiver 16;
When the heat-sensitive device housed in the heat-sensitive device 2 exchanges heat with the cooler 7 and frost adheres to the surface of the cooler 7, and the compressor 9 continues to operate for a certain period of time and the fan repeats cold air circulation, a timer (not shown) is activated. ), the defrost heater 19 is energized, and the frost adhering to the cooler 7 is defrosted by the heat generated by the defrost heater 19. Upon completion of defrosting, the heat sensing section 23 senses the temperature rise, and the defrost heater 19 is activated. cut.

Thereafter, such operation, cold air circulation, and defrosting are repeated to cool the refrigerator-freezer.

Problems that the invention aims to solve In such a defrosting device, the heat-sensitive device is housed within the box-shaped rib of the defrost receiver, but since there is no vertical positioning, the position of the heat-sensing part may fluctuate. There were problems such as an increase in temperature inside the refrigerator and poor cooling inside the refrigerator due to poor defrosting. In addition, ribs were installed for positioning and parts were added, but there were problems such as increased mold costs and parts costs.

In view of the above-mentioned problems, the present invention provides a refrigerator-freezer in which the mounting position of the heat-sensitive part is kept constant to prevent temperature rise and defrosting failure.

Means for Solving the Problems In order to solve the above problems, the present invention provides a protrusion in the inner box hole on the top surface of the heat-sensitive device housed in the ribs of the defrosting water receiver to form a notch. It allows the cord to pass through it and also retains a portion of it.

Effects According to the present invention, a part of the heat-sensitive device housed in the rib of the defrosting water receiver is held in the notch of the inner box hole, thereby eliminating variations.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. Note that the same parts as in the conventional example described above are given the same numbers and explanations are omitted, and only the different parts will be explained. That is, the inner box hole 24 is partially formed by the protrusion 25.
is provided, and a notch 26 is formed in the protrusion 25. And the box-shaped rib 2 of the defrost water receiver 16
2 has an opening 27 partially provided. Thermal device 21
The cord 28 is passed through the opening 27, the direction is determined, and the inclined surface 29 of the defrost water receiver 16 is inserted into the rib 22.
Insert the cord 28 until it makes contact. Further, the heat-sensitive device 21 has a heat-sensitive section 23 in the tube 30,
A cord 28 is connected to both ends, and both ends are welded and sealed. 31 is a tape for fixing the cord 28 to the tube 30.

The upper end of the tube 30 of the inserted heat-sensitive device 21 comes into contact with the lower surface of the protrusion 25 of the inner box hole 24, and the cord 28 passes through the notch 26 provided in the protrusion 25. Note that when the heat-sensitive device 21 is inserted, the rib 22 is made low so that the inner box protrusion 25 is avoided and the heat-sensitive device 21 is inserted obliquely.

With the above-described configuration, the heat-sensitive device 21 does not undergo significant vertical positional fluctuation due to attachment, and can continue to defrost properly.

Effects of the invention As described above, the present invention positions the heat-sensitive device installed in the defrost receiver by using the ribs of the defrost receiver on the lower surface and the cutout of the protruding part of the inner box hole on the upper surface. Since there is no positional fluctuation and reliable defrosting is possible, there are no problems such as internal temperature rise or internal cooling failure due to poor defrosting.

Moreover, it can be done without complicated mold design or addition of parts.
