Abstract

PURPOSE:To contrive the reduction of cost due to the improvement as well as the simplification of workability in assembling by a method wherein one sheet of sheet body, cut so as to have a predetermined configuration, is bent to constitute a dew receiving surface, a retaining part for a defrosting heater and a drip preventing part. CONSTITUTION:A sheet A is cut so as to have a predetermined configuration and a drainage hole 30 is bored at a proper spot, then, the whole of the sheet is formed so as to have the shape of a tray by forming a dew receiving surface 31, slanted so that the dew receiving surface 31 is slanted so as to be lowered toward the drainage hole 30. U-shape retaining grooves 34, whose upper part is opened, and engaging pieces 35, 35 which engage with the open ends are formed respectively at the retaining parts 32, 32 of a glass tube heater H at both sides of a rear side 28a while both sides are bent toward the dew receiving surface 31 and, thereafter, resin parts 36, 36 at both ends of the glass tube heater H are engaged with the retaining grooves 34. Next, the glass tube heater H is covered by a drip preventing part 33 and the engaging pieces 35, 35 of the retaining part 32 are inserted into the engaging holes 37, 37 bored on both ends of the drip preventing part 33, then, the engaging pieces 35, 35 are bent to preclude the drip preventing part 33 from returning upward.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a mounting device for a defrosting heater of a cooler such as a refrigerator.

(B) Conventional technology As shown in the preceding Utility Model Application Publication No. 62-50491, in conventional refrigerators, in order to place a heater below the cooler to melt and remove frost on the cooler, the condenser is Inside was a heater holding plate and a drip-proof cover to prevent defrost water from dripping onto the heater and damaging it.

(c) Problems to be Solved by the Invention The configuration shown here uses a plurality of plates for the exposure surface, the holding plate, the drip-proof cover, etc., so the number of parts is extremely large. There were many problems in terms of assembly workability and cost.

The present invention has been made to solve this problem.

(d) Means for Solving the Problems The present invention provides a dew receiving surface, a holding part for holding the defrosting heater of the cooler, and a defrosting section for the heater by cutting out two plates into a predetermined shape. The drip-proof part prevents dripping of frost water, the holding part holds the heater above the dew receiving surface by being bent toward the dew receiving surface, and the drip-proof part is bent upwards of the heater. This state is maintained by engaging with the holding portion.

(e) Function According to the present invention, the dew receiving surface, the defrosting heater holding part, and the drip-proof part can be constructed only by bending a single plate cut out into a predetermined shape.

(f) Example Next, embodiments of the present invention will be described based on the drawings.

In FIGS. 4 and 5, reference numeral 1 denotes a refrigerator body, in which an inner box 4 is assembled inside an outer box 2, and a heat insulating material 3 is foam-filled between the two boxes 2 and 4. Reference numeral 5 denotes a partition wall that partitions the inside of the inner box 4 into upper and lower parts, and defines a freezing chamber 6 and a refrigerating chamber 7 in the upper and lower parts of the partition wall, respectively. The temperature of the freezer compartment 6 is adjusted to a freezing temperature of about -18°C.

The refrigerator compartment 7 has a partition plate 8 and a vegetable container 9 arranged at its lower part. 10 is a door of the freezer compartment 6, and 11 is a door of the refrigerator compartment 7. The doors 10 and 11 are each rotatably supported on one side of the front opening edge of the refrigerator body 1, and in front of the vegetable container 9 is a pull-out door 1 that can be pulled out at the same time.
It is blocked at 2. 13 is a compressor arranged in the machine room 14 of the refrigerator main body 1, and constitutes a part of the refrigerant circuit. 15 is a cooler installed vertically behind the freezer compartment 6, and is connected to the compressor 17, a condenser (not shown),
The refrigerant circuit is *a together with the pressure reducing means.

20 is a blower placed above the cooling unit 515;
The cold air cooled by the cooler 15 is blown out from the front outlet 21 into the freezer compartment 6, and also blown out from the outlet 22 into the compartment 23 formed in the freezer compartment 6. Furthermore, the blower 20
The accelerated cold air passes through the duct 24 and is also blown out into the refrigerator compartment 7. 25 is a damper thermostat that automatically opens and closes the air outlet 26 of the refrigerator compartment 7 to maintain the refrigerating temperature of the refrigerator compartment 7 at approximately +3°C.

The cold air in each chamber 6, 7, 23 is sucked into the interior through the front end of the partition wall 5 and circulated back to the suction side of the cooler 15. Further, the blower 20 and the compressor 13 function to maintain the freezing temperature of the freezing compartment 6 at an average freezing temperature of about -18° C. by being controlled on and off based on a temperature detection signal from a sensor inside the freezing compartment 6.

A dew tray 28 for receiving and discharging defrosting water from the cooler 15 is provided in a portion located below the cooler 15 at the back of the partition wall 5.
is located. H is a glass tube heater for melting frost on the cooler 15, and is attached to the dew pan 28.

In FIGS. 1 to 3, the dew pan 28 is composed of a single aluminum plate A. As shown in FIGS. That is, an aluminum plate A is cut out into a predetermined shape, a drainage hole 30 is bored at an appropriate location, and the exposed surface 3 is sloped downward toward the drainage hole 30.
By pressing and shaping 1, the rear side 28a and the front side 28
b, the whole is formed into a bucket shape, and the rear side 2 of the dew pan 28
On both sides of 8a, a drip-proof part 33 is cut out and shaped between the holding parts 32.32 of the glass tube heater H and above the holding parts 32.32.

The holding part 32.32 has a U-shaped holding groove 3 open upward.
4 and its open end are formed with engaging pieces 35 and 35 respectively, and after bending from both sides toward the dew receiving surface 31 as shown by the arrow in FIG.
is held in this holding groove 34. As a result, the glass tube heater H is held above the exposed surface 31.

Next, the drip-proof part 33 is placed over the glass tube heater H as shown by the arrow in FIG.
7, and then bend the engaging side 35 as shown by the arrow in FIG. Hold.

The dew pan 28 and the glass tube heater H assembled in this way are attached below the cooler 15 as shown in FIG. 5, so that the glass tube heater H is just below the cooling unit 515. The frost on the upper cooler 15 is melted by the radiant heat of the glass tube heater H, and falls as water or ice blocks. Although this falling object collides with the drip-proof part 33, since the glass tube cover is protected thereby, it does not fall directly onto the glass tube heater H, and the heater H is not damaged. The received defrosting water passes through the dew receiving surface 31 and is discharged from the drain hole 30 through a drain vibrator (not shown) to an evaporation dish (not shown) disposed outside the refrigerator.

(G) Effects of the Invention According to the present invention, the plate is cut out in advance into a predetermined shape to form the exposed surface, the holding part, and the drip-proof part, and then bent to hold the heater in the holding part. By simply engaging the drip-proof part and the holding part, the conventional drip-proof cover can be replaced with a groove, which significantly reduces the number of parts, improves assembly workability, and simplifies the structure to reduce overflow. It is something.
