[0002]

2. Description of the Related Art Inverters that increase the refrigerating capacity of a cooling unit when the heat load is large, and methods of increasing the cooling capacity of a specific section in a multi-temperature zone refrigerator have been used. However, the conventional refrigerator, when accommodating a new high-temperature item in a refrigerator cooled to a predetermined temperature,
An article already cooled to a predetermined temperature and an article having a high temperature have to be accommodated in the same refrigerator, and the thermal influence of the article having a high temperature cannot be prevented. In addition, the cooling air circulation path is fixed, and it is not possible to intensively cool the local portion of the refrigerator that contains a newly hot item.

[0003]

SUMMARY OF THE INVENTION The present invention minimizes the thermal effects of a newly stored hot item on an item that has already been cooled to a predetermined temperature. Provided is a refrigerator for quickly cooling an article having a high temperature to a predetermined temperature.

[0004]

In order to achieve the above object, the invention of claim 1 is directed to a refrigerator cooled by a single cooler, wherein a plurality of independent cooling compartments each having a partition in a refrigerator are provided. A cooling air circulation path formed for cooling the cooling section; a plurality of cooling air supply holes for supplying cooling air to the plurality of cooling sections from the cooling air circulation path; A cooling plate that can be arbitrarily opened / closed, and an operation switch provided corresponding to the cooling section, and a lighting operation of the operation switch or opening of the shielding plate is detected. And a display lamp provided to correspond to the cooling section so as to be turned on. The invention according to claim 2 is characterized in that each of the cool air supply holes comprises a main cool air supply hole that can be opened and closed by the shield plate, and a sub-cool air supply hole that is not opened and closed by the shield plate, and the cooling section is cooling. A second display lamp is provided corresponding to the cooling compartment to notify that the temperature has not reached a predetermined temperature.

[0005]

According to the first or second aspect of the present invention, in order to prevent a thermal effect on an article already cooled to a predetermined temperature in another cooling section, a newly introduced article having a high temperature is specified. The storage is limited to the cooling compartment. At this time, the person using the refrigerator reduced the opening area of the cool air supply holes of the other cooling compartments other than the cooling compartment in which the high-temperature product was stored by the shielding plate, so that the high-temperature product was stored. Increase the cooling air circulation in the cooling compartment. By increasing the amount of circulating cold air, intensive cooling is performed. Furthermore, by turning on the indicator lamp of the cooling compartment in which the high-temperature items are stored, that is, the cooling compartment in which the opening area of the cool air supply hole is not reduced by the shielding plate and remains open, the refrigerator is subsequently used. To the person in charge that the items in the cooling compartment may not be cooled sufficiently. Lighting of this display lamp is performed by the user of the refrigerator performing the lighting operation of the display lamp with the operation switch,
Alternatively, the light is turned on by automatically detecting that the shielding plate is open. After a sufficient time, sufficient cooling may be performed even if the display lamp is turned on, but the management of the time required for cooling in that case can be left to the person who uses the refrigerator. That is, when the person using the refrigerator recognizes that a sufficient time has passed for cooling, the display lamp of the cooling section is turned off at the time when the person uses the refrigerator. The display lamp can be turned off by a user of the refrigerator performing an operation of turning off the display lamp using an operation switch, or by reducing the opening area of the cool air supply hole of the cooling compartment by a shield plate, and the shield plate is automatically turned off. It turns off when it is detected. By providing the indicator lamp in this way, it is possible to recognize that the article in the cooling section where the indicator lamp is lit may not be cooled sufficiently, so care must be taken in managing the time required for cooling. Prompted
It is easier to prevent the relevant cooling compartment from being used before the item has been sufficiently cooled. According to the invention of claim 2, even if the main cool air supply hole is completely closed by the shielding plate, the supply of cool air from the sub cool air supply hole is performed, so that it is possible to prevent a rise in temperature of the corresponding cooling section. it can. Therefore, it is possible to perform the ON / OFF operation to completely close or completely open the shielding plate, so that the fine adjustment of the opening area of the cool air supply hole by the shielding plate becomes unnecessary. In addition, by providing a second indicator lamp that indicates that the cooling compartment has not reached the predetermined temperature, the time required for cooling can be very easily managed, and the corresponding cooling compartment can be cooled before the item is sufficiently cooled. It can be prevented from being used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to embodiments, but the present invention is not limited to the embodiments unless departing from the gist of the present invention. 1 to 7 show an embodiment.

A compartment 4 for accommodating a cooler 3 communicating with the inside 2 of the refrigerator is provided in the upper part of the main body 1, and the cooler 3
The dew receiving plate 5 and the dew receiving plate cover 6 are arranged. At the lower part of the dew receiving plate cover 6, a partition plate 8 for dividing the cooler accommodating section 4 into front and rear portions from the lower surface of the dew receiving plate 5 to the inner box top surface 7 is arranged. Fan 9 to do
Is provided.

On the top surface 7 of the inner box, partition plates 10 and 11 having the same height are formed at the rear part of the inner box and at positions where they come into contact with the partition plate 8 of the cooler accommodating section 4 so as to form ducts 12 and 13. Provided over the entire width of the box, and in contact with the lower surfaces of the ducts 12 and 13, the interior 2 is divided into independent cooling sections A,
A partition 14 for forming B and C is provided.

The two partition plates 10 and 11 of the inner box top 7 and the cover 15 which is in contact with the front part of the inner box top 7 are moved between the inner box side 16 and the cooling section forming partition 14 and the cooling section forming partition. The two ducts 12 and 13 communicating with each section are formed by being provided between the partition 14 and the cooling section forming partition 14, respectively.
Is used as a return duct for guiding the cool air from each of the cooling sections A, B, and C to the fan 9 for circulating the cool air, and the rear duct 13 transfers the cool air cooled by the cooler 3 to each of the cooling sections A, B. , C as a cool air supply duct. The arrows indicate the flow direction of the cool air.

[0010] The cover 15 forming the duct has an opening 17a at the front thereof for guiding the cool air cooled in the cooling section to the return duct, and the rear thereof is opened at the rear in a normal use state. The main cooling air supply holes 18 are closed when the cooling compartments are intensively cooled, and the sub-cooling air supply holes 19 that supply cold air to prevent the temperature of the corresponding cooling compartments from increasing when the main cooling air supply holes are closed. Cold air supply hole 17
b, and a shield plate 2 that slides at a position corresponding to the main cool air supply hole 18 to open and close the main cool air supply hole 18.
0 is arranged.

When the main cool air supply hole 18 is closed by the shielding plate 20, the area of the cool air supply hole 17b in the corresponding duct portion decreases, and the cool air inflow decreases. As a result, the amount of cool air flowing into the other cool air supply holes 17b increases, and the cooling capacity of the corresponding cooling section is enhanced. Since the opening and closing of the main cold air supply hole 18 can be arbitrarily performed, the cooling capacity of an arbitrary section can be increased as necessary.

Display lamps 21 and operation switches 22 corresponding to the number of sections are provided on the upper portions of the front and rear surfaces of the main body.
Are arranged, and the display lamp 21 corresponding to the section where the centralized cooling is performed is turned on by operating the operation switch 22 or the opening of the shielding plate 20 is detected and the display lamp 21 is turned on to determine which section is cooled. It is easy to recognize if it is inside, and it is prevented from being used before cooling to a predetermined temperature.

According to the above embodiment, the cooling sections A, B,
C is independent and the cooling path is also independent, so that it is possible to provide a dish or the like that has already been cooled to a predetermined temperature while supplying and cooling newly cooked food. This is possible in refrigerators. This is very effective when fresh food at room temperature is put in the refrigerator, refrigerated food is taken in and out, or when the beer mug is cooled and served in a beer hall, the collected mug is cooled again. It is a target. In addition, since the thermal effect of the high-temperature articles supplied is reduced, high refrigeration quality can be obtained. (Other Embodiments) In the above embodiments, the interior 2 cooled by one cooler 3 is divided into three independent cooling sections A, B, and C, and the cooling paths are also independent. In other embodiments,
An ice temperature section or a freezing section cooled by another cooler inside or outside of the refrigerator cooled by one cooler 3 is connected independently of or connected to the cooling sections A, B and C. It may be arranged even if it is arranged. Also,
In the above embodiment, the display lamps 21 that are turned on by detecting the lighting operation of the operation switch 22 or the opening of the shielding plate 20 are provided in each of the cooling sections A, B, and C. Instead of lamp 21, cooling compartments A, B,
Alternatively, a second indicator lamp (not shown) for notifying that C has not yet reached the predetermined temperature may be provided. While the second display lamp is on, it is easily recognized that there is not enough time to sufficiently perform freezing. Therefore, the time required for cooling can be very easily managed, and the use of the corresponding cooling section A, B, or C before the article is sufficiently cooled can be prevented.

[0014]

According to the first or second aspect of the present invention, it is possible to store a newly-input high-temperature article only in a specific cooling section, and to set a predetermined temperature in another cooling section. Thermal effects on cooled articles can be prevented. Then, the user using the refrigerator reduces the opening area of the cool air supply holes of the other cooling compartments other than the cooling compartment in which the high-temperature product is accommodated by the shielding plate, so that the cooling in which the high-temperature product is accommodated is performed. It is possible to increase the amount of cooling air circulating in the compartment, so that intensive cooling can be performed. Then, the newly charged high-temperature article can be quickly cooled to the predetermined temperature. Furthermore, by turning on the indicator lamp of the cooling compartment in which the high-temperature items are stored, that is, the cooling compartment in which the opening area of the cool air supply hole is not reduced by the shielding plate and remains open, the refrigerator is subsequently used. The user can be informed that the item in the cooling compartment may not be sufficiently cooled yet. Therefore, attention is paid to the management of the time required for cooling, and it becomes easier to prevent the use of the corresponding cooling section before the article is sufficiently cooled. According to the invention of claim 2, even if the main cool air supply hole is completely closed by the shielding plate, the supply of cool air from the sub cool air supply hole is performed, so that it is possible to prevent a rise in temperature of the corresponding cooling section. it can. Therefore, the shielding plate is completely closed or completely opened, so to speak, ON
The OFF operation is possible, and the delicate operation of the opening area of the cool air supply hole by the shielding plate is not required. In addition, by providing a second indicator lamp for notifying that the cooling compartment has not reached the predetermined temperature, the time required for cooling can be very easily managed, and before the item is sufficiently cooled, the corresponding cooling compartment can be controlled. Can be prevented from being used.
