Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooling method for a refrigerator-freezer with a cooking table, and in particular, the inner surface of a box is divided into a freezer compartment and a refrigerator compartment by partition walls, which are arranged side by side. The present invention relates to a cooling method suitable for cooling each room using a cooling device.

[Background of the invention]

Publicly known examples of cooling systems in which the inner surface of a box is divided into a freezer compartment and a refrigerator compartment by partition walls and arranged side by side are Utility Model Application No. 49-93283 and Utility Model Application No. 53-99720. Both systems install a cooler constituting a cooling device at the back of the freezer compartment, and Utility Model Application No. 49-93283 has a structure in which the cold air passage to the two units is configured by a fixed duct and a sliding duct. In addition, Utility Application No. 53-99720 only shows a structure in which cold air is circulated to the refrigerator compartment through a side passage provided on the side wall of the freezer compartment, and both of them are connected to the refrigerator compartment. The cold air from the cooler installed in the compartment is indirectly circulated to the refrigerator compartment through ducts. No consideration was given to circulating the liquid directly to the refrigerator.

[Purpose of the invention]

An object of the present invention is to provide a rational cooling system for a refrigerator-freezer with a cooking table in which the inner surface of a box is divided into a freezing compartment and a freezing compartment by partition walls.

[Summary of the invention]

That is, a ventilation hole was provided in the partition wall dividing the refrigerator into two units, a cooler constituting the cooling device was installed on the side of the partition wall on the freezer compartment side so as to cover this ventilation hole, and a cooler was installed on the top of the second cooler. The freezer compartment is cooled by the freezer compartment blower, and the refrigerator compartment is directly cooled by the refrigerator compartment fan provided in the ventilation hole on the refrigerator compartment side of the partition wall.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. 30 is a box body of a refrigerator-freezer with a cooking table; an outer box 17 made of a metal plate; an inner box 2 formed by vacuum forming a synthetic resin plate; It is made of rigid polyurethane foam 3. The inner box 2 is integrally formed with a partition wall 2a which is raised from the back to the front, and is partitioned into a freezing compartment 31 and a refrigerating compartment 32. The partition wall 2a is provided with a ventilation hole 2b that communicates with the freezer compartment 31 and the refrigerator compartment 32, and a suction hole 2c that sucks cold air from the refrigerator compartment 32 into the freezer compartment 31. Reference numeral 4 denotes a cooler constituting the cooling device, which is connected to a compressor, a condenser, a suction pipe, etc. (all not shown) to configure the cooling device.

Reference numeral 5 denotes a freezer compartment blower, which is composed of an electric motor and a fan and is installed above the cooler 4. Reference numeral 6 denotes a refrigerator compartment blower, which is constructed of an electric motor and a fan in the same manner as described above, and is attached to the side wall of the refrigerator compartment 32 of the partition wall 2a, covering the ventilation hole 2b. Reference numeral 7 denotes a cooler cover, which has an opening at the top and is attached to cover the cooler 4 and the freezer compartment blower 5.

Reference numeral 8 denotes a blower cover, which has holes for ventilation and is attached to cover the cold room blower 6. 9 is freezer compartment storage shelf, 10゜1
1 is a refrigerator compartment storage shelf. 12 is a machine room cover;
It covers the front side of a machine room (not shown) that houses the compressor and condenser provided on the side of the box body 30. 20 is the freezer compartment door body, 21
．． 22 is the refrigerator compartment door body, both of which are the door outer plate 13. Rigid polyurethane foam 3. Door inner plate 14. s backing 15, each of which has a freezer compartment 31. It is pivotally attached to the box body 30 so that the front opening of the refrigerator compartment 32 can be freely opened and closed.

Reference numeral 16 denotes a partition which separates the opening of the refrigerator compartment 32 from the door body 2.
1 and 22 are formed so that they are in contact with each other. Reference numeral 17 denotes a cooking table installed on the top surface of the box body 30, on which a cutting board or the like (not shown) is placed for cooking. Reference numeral 18 denotes a toy, which is installed at the bottom of the cooler 4 and discharges the defrosting water adhering to the cooler 4 to the outside.The refrigerator-freezer with a cooktop uses the top surface as a so-called cooking table, so it can be used for cooking. It is desirable that the height of the product be good, and the product height is generally 800W1 to 850m. In this configuration, the cooler 4 is installed on the side wall of the freezer compartment 31 of the partition wall 2a, and its front surface is covered with a cooler cover 7, and the freezer compartment blower 5 circulates cold air in the direction of the arrow to cool the freezer compartment 31. . A refrigerator compartment blower 6 is installed on the side wall of the refrigerator compartment 32 of the partition wall 2a so as to cover the ventilation hole 2b.
The cold air generated in
2 is circulated to cool it and reach the cooler 4 installation part through the suction hole 2c. By installing the refrigerator compartment blower 6 so as to be inclined upward, cooling of the refrigerator compartment 32 can be made uniform and stable. The opening area of the cooler cover 7 and the opening area of the ventilation hole 2b are formed so that cold air can be distributed so as to maintain the performance of the freezer compartment and the refrigerator compartment, respectively.

A temperature control device (not shown) is installed in each of the freezing compartment 31 and the refrigerator compartment 32, and the freezing compartment 31. When both the refrigerator compartments 32 reach the required temperature, the operation of the cooling system is stopped, and when the required temperature is reached in the freezer compartment 31 but not in the refrigerator compartment 32, the operation of the cooling system is continued, and the freezer compartment blower 5 When the refrigerating compartment 32 reaches the required temperature and the freezing compartment 31 does not reach the required temperature, the operation control circuit continues to operate the cooling device and stops the operation of the refrigerating compartment blower 6.

〔Effect of the invention〕

As described above, the present invention installs a cooler on the side of the partition wall that partitions the inner surface of the box, cools the freezer compartment side, and
Since cold air can be sent directly to the refrigerator compartment from the ventilation holes provided in the partition wall, there is no need for ducts to guide cold air from the cooler installed at the back as in the conventional case, resulting in inexpensive and reliable cooling. It is possible to obtain a refrigerator-freezer with a cooking table equipped with the above-mentioned method.
