Abstract

PURPOSE:To prevent sealing properties of a sealing material for an air flow duct from being deteriorated due to the damage or coming-off of the sealing material when a control panel is mounted, and to enable the control panel to be mounted by simple and easy work by providing a plurality of locking projection pieces at the top end of the control panel and an inclined surface at the bottom end thereof, inserting the locking projection pieces into locking holes formed on the ceiling-plane of a refrigerating chamber, and contacting the inclined surface under pressure to a surface having the opening of a second air-flow duct. CONSTITUTION:By inserting locking projection pieces 17 at the top end of a control box 15 into locking holes 19 and moving the control box 15 in the arrow direction, an inclined surface 18 at the bottom end of the control box 15 is contacted under pressure to a surface having the opening of a second air-flow duct 11, so that an air flow duct 10 of the control box 15 and the air-flow duct 11 communicate to each other while the top end of the first air-flow duct 10 communicates to a cooling air passage, whereby the control box 15 can be connected reliably without causing a sealing material 16 to be damaged or coming-off. Since the top end of the control box 15 is held by the engagement of the locking projection pieces 17 and the locking holes 19, the mounting of the control box 15 can be fixed reliably by screw clamps at two places at the lower part of the control box 15.

Cold room 3 is cooled with forced ventilation.

In addition, in the vegetable compartment 4, the cooling air that has circulated in the low temperature room 3 flows through the third ventilation duct 12 formed in the partition wall 7 as shown by the arrow, so that the strong control i! IFIL is being cooled.

The first Hakufu duct 10 is formed of a foamed heat insulating material 13 whose upper end communicates with the cooling ventilation passage and whose lower end communicates with the second ventilation duct 11. It is composed of a control spring Iv15 equipped with a damper thermostat 14 that controls the temperature of the refrigerator compartment 2, cold room 3, etc. by controlling the amount of cooling air to be cooled.
It is fitted and fixed from the front with screws, etc. as shown by the chain line arrow in the figure.

In the above-mentioned conventional method *a, when the control spring/v16 is fitted into the back wall surface of the refrigerator compartment 2, seals provided on both upper and lower end surfaces of the ventilation duct 10 are removed. While compressing the material 16,
In order to communicate with the upper cooling ventilation passage and the lower second ventilation duct 11, the sealing material 16 is deformed and damaged, and the workability is poor, and dew condensation occurs in the communication area between the two ducts (10 and 11). Something happened.

The invention is intended to solve these conventional problems, and prevents deterioration of the sealing property due to damage or detachment of the sealing material of the ventilation duct when installing the control spring y, and it can be installed easily and easily. To achieve the above object, the present invention provides a plurality of pieces of iB bowls at the upper end of the control panel;
To provide an inclined surface at the lower end, insert the locking/protruding piece into a stop hole formed on the ceiling surface of the refrigerator compartment, and attach the inclined surface to the second
Press against the opening surface of the ventilation duct.

According to the above-described structure, the control box (1) rotates toward the back while inserting the locking projection piece into the retaining hole on the ceiling surface of the refrigerator compartment, and connects the inclined surface to the opening surface of the second ventilation duct. Since the pressure contact is applied, the holding and fixing of the control box can be done by simply inserting the locking protrusion piece and the locking hole, and there is no need for screws or other fittings, and the locking can be done even if the control box is slightly uneven in size. Since positioning is achieved by the pivoting of the protruding piece and the locking hole, the first ventilation duct and the second alt duct can be clearly communicated, and damage and deformation of the sealing material can be prevented, allowing secure installation. be.

Example An embodiment of the present invention will be described below with reference to the drawings.

It should be noted that if the numbers in the figure correspond to the conventional example, the conventional example is used.

In FIGS. 1 to 4, the inside of the refrigerator main body is divided into a freezer compartment 1, a refrigerator compartment 2, a cold room 3, and a vegetable compartment 4 in order from above by partition walls 5, 6.7.

A cooler 8 and a blower 9 are installed in the deep part of the freezer compartment 1 to form a cooling air passage, and the cooling air of this cooling air passage is distributed to the partition walls 6, 6, . Each of the chambers 1.2, 3.4 is cooled by forced ventilation through a ventilation path formed in a T-shape. 1o is a first ventilation duct whose upper end communicates with the cooling ventilation passage and whose lower end communicates with the opening surface of the second ventilation duct 11 that ventilates cooling air into the cold room 3; It is composed of a control box 16 that houses a damper thermostat 14.

A sealing material 16 such as flexible polyethylene foam is attached to the upper and lower ends of the control box 16. Reference numeral 17 designates a plurality of floor protrusions protruding from the upper edge of the control box 16, and reference numeral 18 represents an inclined surface formed at the lower end of the control box 16.

19 is a locking hole formed in the inner ceiling surface of the refrigerator compartment 2;
It engages with the locking protrusion piece 17 of the control box 16, and in this engaged state, the upper end of the first ventilation duct) 10 communicates with the cooling ventilation passage, and the lower end of the first ventilation duct) 10 is provided at a position communicating with the opening surface of the second ventilation duct 11.

2o is a ventilation port provided on the front surface of the control box 16 and communicates with the first ventilation duct 10 to ventilate cooling air into the refrigerator compartment 2; 21 is provided on the opposite side of the control box 15 from the first ventilation duct 10; This is a suction duct.

With the above-described configuration, the control box 16 can be rotated in the direction of the arrow by inserting the locking projection piece 17 at the top end into the locking hole 19, as shown in FIG.
B is brought into pressure contact with the opening surface of the second ventilation duct 11 so that the ventilation ducts 10 and 11 communicate with each other and the upper end of the first ventilation duct 10 communicates with the cooling ventilation passage, thereby preventing damage or detachment of the sealing material 16. You can connect reliably without any problems.

Furthermore, the control box 16 can be mounted because the upper end is held by the engagement between the locking protrusion 17 and the locking hole 19.
As shown in the fourth prisoner, the screws are securely fixed at two locations at the bottom. However, even if the dimensions of the control box 16 are slightly uneven, it is positioned by the engagement between the locking protrusion 17 and the locking hole 19, and the locking type absorbs the unevenness, making the installation work easy and reliable. It is carried out in

Effects of the Invention As is clear from the above description, the present invention provides a plurality of locking protrusions at the upper end of the control panel and an inclined surface at the lower end, and the locking protrusions are attached to the ceiling of the refrigerator compartment. Since the control box is inserted into a locking hole formed in the second ventilation duct and the slanted surface is pressed against the opening surface of the second ventilation duct, the control box can be installed without damaging or detaching the sealing material and making it easy to connect the ventilation duct. There is no need to worry about condensation forming on parts.

Also, in terms of installation work, since the upper part is held by the engagement of the locking protrusion and the locking hole, there is less need for fixing means such as screws, and the number of man-hours can be reduced.

Furthermore, dimensional variations can be absorbed by the retaining portion, and the connection can be ensured, which has a number of effects.
