Fig. 1 is a schematic structural view of a refrigerator 1 according to an embodiment of the present invention. Fig. 2 is a schematic structural view of a part of a refrigerator 1 according to an embodiment of the present invention.

As shown in fig. 1 and 2, in one embodiment, the refrigerator 1 includes a storage item 110, a receiving cavity 120, and a heating device 130. The storage member 110 is formed with a storage cavity 111 for placing food. The storage member 110 is placed in the receiving cavity 120. The accommodating chamber 120 is provided with an air inlet 121 and an air outlet 122 communicating with the outside, and an air duct surrounding the storage article 110 is defined between the storage article 110 and the closed accommodating chamber 120. The heating device 130 is provided in the air duct to heat the air flow entering from the air inlet 121 and to allow the heated air flow to pass through the upper and lower sides of the storage 110.

As shown in fig. 1 and 2, the refrigerator 1 includes a cabinet 10 and a door 20. The cabinet 10 defines therein a receiving chamber 120 and a refrigerating chamber 140. The receiving chamber 120 and the refrigeration chamber 140 are separated by a baffle, that is to say a baffle acts both as a side wall of the receiving chamber 120 and as a side wall of the refrigeration chamber 140. An evaporator and a fan are arranged in the refrigeration cavity 140, the evaporator releases cold in the refrigeration cavity, and the fan is used for conveying the cold in the refrigeration cavity outwards. An air inlet 121 and an air outlet 122 are formed on the baffle plate, and the accommodating cavity 120 is communicated with the refrigeration cavity 140 through the air inlet 121 and is also communicated with the refrigeration cavity 140 through the air outlet 122.

Referring to fig. 1 and 2, the receiving cavity 120 has an opening facing the door body 20 to allow the article storage member 110 to be put into and taken out of the receiving cavity 120. During the storage of the food, the opening of the receiving cavity 120 can be closed, so that the receiving cavity 120 is in a closed state. Meanwhile, after the storage member 110 is placed in the accommodating cavity 120, a space is formed between the storage member and the inner wall of the accommodating cavity 120, so that an air duct surrounding the storage cavity 111 (i.e., a part of the space of the accommodating cavity 120 not occupied by the storage member 110) is defined.

The storage part 110 is a drawer, the drawer is drawably disposed in the accommodating cavity 120, a partition 123 covers the top of the drawer entering the accommodating cavity 120, and a portion of an air duct is formed between the partition 123 and the top wall of the accommodating cavity 120.

Specifically, the partition 123 is a member fixed in the accommodating chamber 120, and may be integrally formed with the accommodating chamber 120 or may be separately installed. The drawer is disposed at the bottom of the partition 123 such that the inner space of the drawer can be exposed to the user's view when the drawer is withdrawn from the receiving chamber 120, thereby facilitating the user to take and put food. When the drawer is retracted into the accommodating cavity 120, the partition 123 is located at the bottom side of the partition, so that the partition 123 and the side wall of the drawer enclose the storage cavity 111 together, and an air duct surrounding the storage cavity 111 is formed among the partition 123, the side wall of the drawer and the inner wall of the accommodating cavity 120.

It should be noted that the partition 123 may be directly disposed on the drawer and can be opened or closed. That is, the partition 123 can enter and exit the receiving chamber 120 together with the drawer, and the user can open the drawer by opening the partition 123.

The opening of the accommodating chamber 120 may be closed by a door that moves independently, or the opening of the accommodating chamber 120 may be closed by a door that moves together with the drawer and is provided at the front side of the drawer.

Referring to fig. 1 and 2, in detail, the entire refrigerator 1 has a front end close to the door 20 and a rear end far from the door 20. Referring to the airflow direction arrows in fig. 2, the cold air in the refrigeration cavity 140 enters the accommodating cavity 120 from the air inlet 121, and after passing through the heating device 130, the airflow flows to the front end of the accommodating cavity 120 along the air channel region between the upper side of the partition 123 and the top wall of the accommodating cavity 120. Reaches the front end of the receiving chamber 120 and flows down along the air passage area at the front end of the storage object 110. The airflow then flows along the air duct region between the underside of the article storage 110 and the bottom wall of the receiving cavity 120 towards the rear end of the receiving cavity 120 and then back into the refrigeration cavity 140 from the air outlet 122. That is, an air flow around the storage chamber 111 is formed in the receiving chamber 120.

Therefore, in the solution of the present embodiment, the airflow forms a temperature environment around the storage cavity 111 in the accommodating cavity 120, so as to adjust the temperature in the storage cavity 111, thereby preventing the airflow from blowing the food in the storage cavity 111. Moreover, after the air flow enters the air duct from the air inlet 121, the heating device 130 can heat the air flow, so that the air flow is heated when the temperature of the air flow is too low, the temperature of the air flow flowing in the air duct is prevented from being too low, the temperature in the storage cavity 111 is prevented from generating large fluctuation, the temperature in the storage cavity 111 is kept in the temperature range for keeping meat in a supercooled state, and the meat food is prevented from being directly frozen in the refrigeration process.

In addition, the storage articles 110 are arranged as drawers, and the partitions 123 for covering the drawers are arranged. The partition 123 forms a part of the air channel with the top wall of the accommodating chamber 120, so that the air channel surrounding the drawer is formed in the accommodating chamber 120, and the air flow is prevented from blowing the food placed in the drawer. And the drawer is convenient for taking and placing food.

Further, through setting up air intake 121 on the top of the back side wall that holds chamber 120, because place the diapire at the food laminating storage article 110 of storing part 110, so, under the condition that heating device 130 does not reach operating condition completely, can reduce the effect of the air current of not fully heating to food in the storing chamber 111 to guarantee the effect of the air current after the fully heating to storing chamber 111. The heating device 130 is disposed at the rear end of the storage device 110, and can heat the air flow in time.

It should be noted that, in some other embodiments of the present application, the storage device 110 may also be a structure with an opening at the front end, and the front end opening is provided with a separately opened and closed door. Or the door that opens the receiving cavity 120 can simultaneously close the front opening of the storage item 110 when closed.

It should be noted that the air inlet 121 may also be disposed at other positions on the rear sidewall of the accommodating cavity 120, for example, a position near the top of the accommodating cavity 120 but capable of being covered by the storage component 110 in the front-back direction. In addition, the heating device 130 may also be directly covered at the air inlet 121, or may be disposed at a position having a certain distance from the rear end of the storage article 110.

Specifically, the refrigerator 1 may be configured as follows: the inlet opening 121 is disposed at a rear side wall of the accommodating chamber 120, the heating device 130 is disposed at one of an upper side and a lower side of the storage object 110 near the inlet opening 121, and a distance between the heating device 130 and a rear side of the accommodating chamber 120 is smaller than a distance between the heating device 130 and a front side of the accommodating chamber 120.

For example, the inlet opening 121 is disposed at the bottom end of the rear sidewall of the receiving chamber 120, and the heating device 130 is disposed at the lower side of the storage member 110.

Fig. 3 is a schematic structural view of a part of a refrigerator according to another embodiment of the present invention.

Fig. 4 is a schematic structural view of a refrigerator 1 according to still another embodiment of the present invention. Fig. 5 is a schematic structural view of a part of a refrigerator 1 according to still another embodiment of the present invention;

as shown in fig. 4 and 5, in the present embodiment, the refrigerator 1 includes a secondary heating device 150 disposed at a lower side of the storage 110. Specifically, the heating device 130 is disposed on the upper side of the storage 110, and the sub-heating device 150 is disposed on the lower side of the storage 110.

It can be understood that, since the food placed on the storage member 110 is fitted to the bottom wall of the storage member 110, the activated secondary heating device 150 can rapidly warm the storage cavity 111 by disposing the secondary heating device 150 at the lower side of the storage member 110. Therefore, when the heating device 130 is turned on, the secondary heating device 150 is also turned on at the same time, and even if the food is in a freezing risk due to the hysteresis of the operation of the heating device 130, the food can be prevented from being frozen by the slight amount of heat generated by the secondary heating device 150, so that the food can be better ensured to be in a supercooled state.

Fig. 6 is a schematic structural view of a refrigerator 1 according to still another embodiment of the present invention.

Referring to fig. 6, in the present embodiment, the refrigerator 1 includes a first temperature sensor 160 disposed at a side of the intake vent 121 remote from the receiving chamber 120 to detect a temperature of the airflow entering the intake vent 121. In other words, the first temperature sensor 160 may be disposed in the refrigerating chamber 140 so as to detect the temperature of the air flow to be introduced into the intake vent 121.

In the solution of the present embodiment, by providing the first temperature sensor 160 on the side of the air inlet 121 away from the accommodating chamber 120, the temperature of the air flow before entering the air inlet 121 can be detected, so as to better control the time for which the heating device 130 is turned on. For example, when the temperature detected by the first temperature sensor 160 is less than a preset value, the heating device 130 is turned on in advance, and when the temperature of the air flow reaches the preset value, the heating device 130 is turned on completely, so that the heating effect on the air flow is ensured, and the temperature in the accommodating chamber 120 is maintained within a proper range.

It should be noted that, in some other embodiments of the present application, the first temperature sensor 160 may not be provided, but the heating device 130 may be turned on after a certain time period after the cooling starts.

Specifically, after the air flow entering the accommodating cavity 120 from the air inlet 121 passes through the heating device 130, the air flow passes through the second temperature sensor 170, so that the second temperature sensor 170 can detect the temperature of the air flow heated by the heating device 130, the closing time of the heating device 130 can be better judged, and the over-high temperature in the storage cavity 111 is avoided.

It should be noted that, in some other embodiments of the present application, the second temperature sensor 170 may not be provided, and the heating device 130 may be turned off after the heating device 130 is turned on for a certain time.

Fig. 8 is a schematic structural view of a refrigerator 1 according to still another embodiment of the present invention. Fig. 9 is a schematic structural view of a part of a refrigerator 1 according to still another embodiment of the present invention.

During cooling, the damper 180 is opened to allow airflow into the receiving cavity. During the cooling stop, the damper 180 is closed, so that the cool air can be prevented from being dissipated into the receiving chamber 120.

As shown in fig. 1 to 9, in one embodiment, the air outlet 122 is inclined upward along an end close to the accommodating chamber 120 to an end far from the accommodating chamber 120. So that the escape of cold air from the outlet 122 into the receiving chamber 120 can be reduced.

In one embodiment, the refrigerator 1 includes a magnetic field generating device for generating a magnetic field covering the storage chamber 111. Specifically, the magnetic field generating device may be disposed at the top and/or bottom of the storage object 110, thereby generating a relatively uniform magnetic field within the storage cavity 111, which is advantageous to assist the food to be maintained in a supercooled state.
