Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a refrigerator that mainly uses a damper thermostat to control the temperature inside the refrigerator.

BACKGROUND ART A conventional refrigerator using a damper thermostat and having a structure in which cold air from a cooling chamber is guided to a refrigerator chamber through a duct is disclosed in Japanese Patent Application Laid-Open No. 59-219682. This conventional example will be briefly explained with reference to FIGS. 2 and 3. 1 is the refrigerator body, 2 is the freezer compartment, 3
is the cold storage room. There is a cooler 4 in the back of the freezer compartment 2,
A fan (not shown) for circulating cold air is provided at the top of the cooler 4. On the other hand, a compartment 12 is arranged in the upper part of the refrigerator compartment 3, and a temperature control device 7 with a built-in damper thermostat 6 is installed at the back of the compartment 12.
is provided. The cooler 4 and the temperature control device 7 communicate with each other through a discharge duct 9 provided in a partition heat material 8 that partitions the freezing compartment 2 and the refrigerator compartment 3.

Continuing from this discharge duct 9, a duct 10 is provided inside the temperature control device 7, and the duct 10 is opened at the terminal end, and this opening 10a is connected to the damper thermostat 6's buffer 6a. It is opened and closed by the rotation of.

Above the duct 10 is a cold air inlet 10b.
and a storage section 1 that houses the damper thermostat 6.
0c is configured.

The insulation materials 11a and 11b, which are divided into front and rear parts so as to cover the periphery of the duct 10, house and insulate the duct housing the damper, and also serve as an air path for discharging air into the refrigerator compartment 3. There is.

6b is a thermosensitive cylinder for temperature sensing of the damper thermostat 6.

In this configuration, cold air generated by heat exchange in the cooler 4 is distributed to the freezer compartment 2 and the refrigerator compartment 3 by a cold air circulation fan (not shown). The cold air sent to the refrigerator compartment 3 is sent from the discharge duct 9 in the partitioned heat material 8 to the duct 10 in the temperature control device 7, and is sequentially discharged into the refrigerator compartment 3 through the opening 10a and the insulating member recess 11c. Provides a cooling effect. At this time, the damper thermostat 6 detects the internal temperature of the refrigerator compartment 3 using the heat-sensitive cylinder 6b, and rotates the buffer 6a to open and close the duct opening 10a to control the inflow of cold air.

Problems to be Solved by the Invention However, in the above configuration, since the cold air is connected to the temperature control device 7 from the discharge duct 9 through the duct 10, the cold air is connected to the temperature control device 7 from the temperature control device 7. A dedicated duct was constructed according to the size of the compartment installed in front of the damper thermostat 6, and the temperature control dial 6c of the damper thermostat 6 was made operable. For this reason, the duct 10 could not be used for multiple purposes, which caused an increase in molding costs.

In view of the above-mentioned problems of the conventional example, the present invention realizes the dual use of a temperature control device housing a damper thermostat and a duct by improving the shape of the duct and the heat insulating material of the duct.

Means for Solving the Problems In order to solve the above problems, the present invention includes a temperature control device, a duct that houses a damper thermostat and whose opening is opened and closed by a buttful, and the front, rear, left, right, and top surfaces of this discharge tact. A discharge duct having an opening formed on the lower surface of the partitioned heat material and a cold air inlet of the duct are connected through an opening in the heat insulating material covering the top surface. .

Effects With the above configuration, the present invention provides a heat insulating material that forms an opening between the ducts of the temperature control device that are continuously connected to the discharge duct. This can be handled by changing the thickness.

Embodiment An embodiment of the present invention will be described below with reference to FIG.

1 is a refrigerator main body, 3 is a refrigerator compartment, 6 is a damper thermostat, 15 is a temperature control device, 16 is a duct, and 17a, 17b are heat insulating materials.

Duct 16 built into temperature control device 15
is insulated by heat insulating materials 17a and 17b covering the front and rear surfaces and the left and right sides, but there is a duct 1 above the duct.
A heat insulating material 17d having an opening 17c that communicates the cold air inlet 16b of No. 6 with the opening 9a facing the lower surface of the discharge duct 9 is disposed.

In the above configuration, the air generated by heat exchange in the cooler 4 passes through the cold air discharge duct 9 and enters the duct 16 housed inside the temperature control device 15 placed in the upper part of the back of the refrigerator compartment 3. , flows through the opening 17c formed in the heat insulating material 17d, and flows into the opening 16.
It is discharged from a, flows into the refrigerator compartment 3, and performs a cooling action.

At this time, the damper thermostat 6 is
detects the internal temperature of refrigerator compartment 3 and
By rotating a, the opening 16a of the duct is opened and closed to control the inflow of cold air. Like this,
By configuring the opening integrally with the duct insulation material and giving it the function of a connecting duct, the refrigerator main body discharge duct 9 and the temperature control device 15, which functions when assembled, have versatility, depending on the size of the compartment. Because the dial is located below the compartment of the damper thermostat, this can be done by simply changing the thickness of the insulation material 17d without changing the external shape of the temperature control device 15, and there is no need to create a new duct. do not have.

Effects of the invention As described above, the invention integrates an opening into the heat insulating material that insulates the duct that houses the damper thermostat in the temperature control device. (1) The combination of the damper thermostat and the duct is If there is only one type, it can be shared with other models, leading to standardization.

(2) Since it contributes to the miniaturization of the duct shape, it is possible to reduce the cost of plastic molding tools.

(3) Since the cold air inlet is molded with heat insulating material, quality and performance can be stabilized because the complex shape that also serves to ensure sealing of the air passage joints is formed by molding foamed heat insulating material.

With these effects, it is possible to provide a refrigerator having an effective means of simplifying and sharing the temperature control device.
