2. Description of the Related Art When the heat load is large, methods such as using an inverter to increase the refrigerating capacity of a cooling unit and increasing the refrigerating capacity of a specific compartment in a multi-temperature range refrigerator are being used. As a multi-temperature zone refrigerator, patent application No. 2-32
A configuration shown in No. 0413 is known.

[0003] However, in conventional refrigerators, when newly storing high-temperature items in the refrigerator that has been cooled to a predetermined temperature,
Items that have already been cooled to a predetermined temperature and items with a high temperature must be stored in the same warehouse, making it impossible to prevent the thermal effects of the items with a high temperature.

[0004] Furthermore, the cold air circulation path is fixed, making it impossible to intensively cool the local area of the refrigerator containing new high-temperature items.

[0005] As a refrigerator with such a configuration, Japanese Patent Application No.
A configuration shown in No. 194920 is known.

[Problems to be Solved by the Invention] In conventional refrigerators, when a new high-temperature item is stored in a refrigerator that has been cooled to a predetermined temperature, the product that has been cooled to a predetermined temperature and the high-temperature item Items had to be stored in the same warehouse, making it impossible to prevent the effects of heat from high-temperature items. Furthermore, the cold air circulation path is fixed, making it impossible to centrally cool a local area within the refrigerator. The present invention minimizes the thermal influence of newly stored high-temperature items on the stored items that have been cooled to a predetermined temperature, and also allows the newly placed high-temperature items to be quickly placed in the specified position. To provide a refrigerator whose purpose is to cool down to a temperature of

[0007]

[Means for solving the problem] A partition wall is provided in the interior of a refrigerator cooled by a single cooler to form two or more independent cooling compartments, and independent cold air is provided to cool each compartment individually. Circulation paths are arranged, and a cold air supply fan that can arbitrarily change the amount of cold air supplied is provided in an opening provided in each cold air circulation path to cool the corresponding cooling section.

[0008]

[Function] By creating partitions in the warehouse and forming multiple independent cooling compartments, it is possible to limit newly introduced high-temperature items to a specific cooling compartment and store them. Thermal effects on the item, which has been cooled to a predetermined temperature, are prevented.

Furthermore, since the cooling compartments are made independent and the cold air circulation path is also made independent, it becomes possible to cool the newly introduced load while maintaining the temperature of the already cooled items at a predetermined temperature.

[0010] Furthermore, if necessary, by operating the fan of the cooling compartment in which the new high-temperature items are stored, the amount of cold air circulating in the relevant compartment is greatly increased, so that the new load can be quickly brought to a predetermined temperature. It can be cooled up to.

Furthermore, since the fans provided in each cold air circulation path can be operated as desired, it is possible to increase the cooling rate of any cooling section.

[0012] Furthermore, when high-temperature items are stored in all the cooling compartments of the refrigerator, by operating all the fans, the amount of cold air circulated increases and the cooling rate is increased.

, 20b, 20c.
An operation switch 16 for driving 0 and a display lamp 17 for displaying its operating state are provided. The operation switches 16 are provided in correspondence with the number of cold air supply fans 30, and in this embodiment, three operation switches 16 are provided corresponding to the three cold air supply fans 30. The operation switches 16 are arranged in a row horizontally, and the cooling compartments 20 are arranged in order from the left side.
a, 20b, and 20c.

In this embodiment, the cold air supply fan 30 is driven by the operation switch 16, but each cooling section 2
0a, 20b, and 20c may be provided with temperature sensors, and each cold air supply fan 30 may be driven based on the temperature within each cooling section 20a, 20b, and 20c.

Next, the cooling operation of the refrigerator of this embodiment will be explained based on the above configuration. First, each cooling section 20a
, 20b, 20c and are sufficiently cooled, each cold air supply fan 30 is in a stopped state, and the cold air supplied from the cooler storage compartment 7 to the cold air supply duct 11b is supplied to the duct cover 13. From the gap between the opening 15 and the cold air supply fan 30, each cooling section 20a, 20b, 2
The cool air that has cooled the coolant is sucked up by the cold air circulation fan 9, guided to the return duct 11a through the opening 14, and circulated to the cooler 3.

Next, when the cooled material is taken out from a specific cooling section 20 and the cooled material is newly stored in the cooling section 20,
(Assuming that the specific cooling compartment 20 is the cooling compartment 20a) The temperature of the cooled material newly stored in the cooling compartment 20a is higher than that of the cooled material stored in other cooling compartments 20, so the cooled material should be removed immediately. For cooling, the amount of cold air supplied into the cooling compartment 20a is increased by operating the operation switch 16 corresponding to the cooling compartment 20a and driving the cold air supply fan 30 corresponding to the cooling compartment 20a. When it is confirmed that the temperature in the cooling compartment 20a displayed in the section 36 is sufficiently cooled like the other cooling compartments 20,
The operating switch 17 is operated to stop the driving of the cold air supply fan 30, and the coolant is stored in each of the aforementioned cooling sections 20 and is sufficiently cooled.

The cooling air supply fan 30 is stopped by operating the operation switch 17, but a temperature sensor is provided in each cooling section 20, and the cooling air supply fan 30 is driven by the temperature sensor. It may be configured to detect that the temperature within the compartment 20 has become similar to that of other cooling compartments 20 and stop driving the cold air supply fan 30.

Furthermore, since the display lamp 17 indicating the cooling state of each cooling section 20 is driven in response to the operation of the operation switch 16 and the driving of the cold air supply fan 30 by the temperature sensor, the cooling state of each cooling section 20 can be easily determined. can be visually recognized.

It is also possible to optionally drive a plurality of cold air supply fans 30 in order to cool the load increased by newly storing cooling material in the plurality of cooling compartments 20. That is, when a new object to be cooled is stored in the cooling compartments 20a, 20b, this is handled by driving the cold air supply fans 30 corresponding to the cooling compartments 20a, 20b. It is also possible to drive all the cold air supply fans 30.

Furthermore, the cooling section 20 in which the coolant is stored drives the cold air supply fan 30, and the cooling supply fan 30 corresponding to the cooling section 20 in which the coolant is not stored is driven.
It may be configured to stop.

The cold air supply fan 30 is connected to the operation switch 1
6 etc., the configuration was such that the cold air supply fan 30 is in a driving state or a stopped state, but the driving amount of the cold air supply fan 30 is changed to be variable in strength and weakness.
More fine-grained temperature control is achieved by increasing the drive amount immediately after storing the coolant and weakening the drive amount as it cools, and by selecting the drive amount of the cold air supply fan 30 according to the amount of coolant stored. is possible.
