Background

Refrigerators are home appliances for storing food materials. Along with the improvement of the living standard of people, users increasingly pay attention to the fresh-keeping effect of food materials. At present, a part of refrigerators can realize supercooling storage of food materials, namely, the supercooling storage is to store meat food materials in a supercooled state, namely, the temperature is below the freezing point of meat food, but the meat food is not frozen, so that the taste of the meat food is kept under the condition of ensuring that the meat food has longer storage time.

However, since the supercooled state of meat is very unstable, during the cooling process, the supercooled state of food is lost due to the fact that the temperature in the whole space is too low, although the temperature in the whole space is not yet required, so that the supercooled storage effect of food is lost due to the fact that the supercooled state of food is frozen.

A further object of the utility model is to improve the mixing effect of the two streams.

It is a further object of the utility model to provide a more thorough mixing of the two streams.

the accommodating cavity is provided with a first air inlet and an air return opening;

the storage object is arranged in the accommodating cavity, an air delivery duct extending to the front side of the storage object is formed between the top of the storage object and the inner top wall of the accommodating cavity, and the first air inlet is positioned above the top end of the storage object so that cold air entering from the first air inlet can flow to the front side of the storage object through the air delivery duct;

the air mixing fan is arranged at the rear side of the storage object and is positioned between the first air inlet and the air return opening, and the opened air mixing fan drives air flow flowing to the air return opening to the air delivery duct so as to be mixed with cold air entering from the first air inlet.

According to the refrigerator, the air delivery duct is formed between the top of the storage object and the inner top wall of the accommodating cavity, and the air mixing fan is arranged in the accommodating cavity. When the air mixing fan is started, the air mixing fan can enable the air flow subjected to heat exchange to flow to the air delivery duct. And then the air flow after heat exchange and the air flow which just enters the accommodating cavity from the first air inlet are mixed in the air delivery channel, so that the temperature of the air flow in the air delivery channel is increased compared with that of the air flow which enters the accommodating cavity from the first air inlet.

Furthermore, the refrigerator of the utility model is provided with a plurality of wind shields at the top of the storage object, and after the air flow enters the air delivery duct. The air flow is guided by the wind shield, and a flow path which circulates back and forth from left to right and from right to left is formed while flowing forward.

As shown in fig. 1 and 2, in one embodiment, the refrigerator includes a receiving chamber 110, a storage object 200, and a wind mixing fan 300. The accommodating chamber 110 is formed with a first air inlet 111 and an air return 112. The storage article 200 is disposed within the receiving chamber 110. An air delivery duct 120 extending to the front side of the storage article 200 is formed between the top of the storage article 200 and the inner top wall of the receiving chamber 110. The first air inlet 111 is located above the top end of the storage article 200, so that the cool air entering from the first air inlet 111 can flow to the front side of the storage article 200 through the air delivery duct 120. The air mixing fan 300 is disposed at the rear side of the storage object 200 and between the first air inlet 111 and the return air inlet 112. The opened air mixing fan 300 drives the air flow flowing toward the return air inlet 112 to the air delivery duct 120 to mix with the cool air entering from the first air inlet 111.

Referring to fig. 1 and 2, in particular, the refrigerator includes a cabinet 100, and a receiving chamber 110 is defined in the cabinet 100. The first air intake 111 and the air return 112 are formed on the rear sidewall of the accommodating chamber 110. The cabinet 100 is also formed with a refrigerating chamber 130. An evaporator and a cooling fan are provided in the cooling chamber 130, and the evaporator is used for releasing cold in the cooling chamber. The cooling fan is used for forming cold air, so that cold energy enters the accommodating cavity 110 from the first air inlet 111.

With continued reference to fig. 1 and 2, the storage article 200 is a drawer that is drawably mounted in the receiving cavity 110. The storage article 200 also includes a shutter that covers the top opening of the drawer when the drawer is retracted within the receiving cavity 110. An air delivery duct 120 is formed between the top of the shutter and the inner top wall of the receiving chamber 110. The air delivery duct 120 extends to the front side of the storage object 200.

Further, the first air inlet 111 is located above the top end of the shutter, i.e. above the top end of the storage article 200. And thus cold air introduced from the first air inlet 111 can enter the air delivery duct 120 and flow forward along the air delivery duct 120. Until flowing in front of the storage article 200, the cool air begins to flow downward and then backward, and finally returns from the return air inlet 112 into the cooling chamber 130.

With continued reference to fig. 1 and 2, a wind mixing blower 300 is provided at the rear side of the storage article 200. The air mixing fan 300 is mounted on a support plate which can play a role of separation to prevent cold air from flowing directly from the rear side of the storage article 200 to the return air inlet 112. The support plate may not be provided, and the shielding member may be located as close to the first air inlet 111 as possible.

The return air inlet 112 is located at the air inlet side of the air mixing fan 300, and the air delivery duct 120 is located at the air outlet side of the air mixing fan 300. That is, when the air mixing fan 300 is turned on, the air mixing fan 300 can attract the air flow flowing to the air return opening 112, so that the air flow changes direction and flows into the air delivery duct 120. Because these streams have already undergone heat exchange, the temperature is higher. These heat-exchanged air streams are mixed with the air stream just entering the accommodating chamber 110 from the first air inlet 111 in the air delivery duct 120, so that the temperature of the air stream in the air delivery duct 120 increases.

In the solution of the present embodiment, the air delivery duct 120 is formed between the top of the storage object 200 and the inner top wall of the accommodating chamber 110, and the air mixing fan 300 is disposed in the accommodating chamber 110. When the air mixing fan 300 is turned on, the air mixing fan 300 can make the air flow after heat exchange flow to the air delivery duct 120. The air flow after heat exchange and the air flow just entering the accommodating cavity 110 from the first air inlet 111 are mixed in the air delivery duct 120, so that the temperature of the air flow in the air delivery duct 120 is increased compared with the temperature of the air flow entering the accommodating cavity 110 from the first air inlet 111. Therefore, the gap between the refrigerating air flow and the set storage temperature is reduced, and the situation that the local temperature is too low due to the too low air temperature is effectively avoided, so that the situation that the supercooled state of the food material is damaged is effectively reduced.

As shown in fig. 3 and 4, in one embodiment, the receiving chamber 110 is formed with a second air inlet 113. The second air inlet 113 is located at an air inlet side of the air mixing fan 300. Specifically, when the second air inlet 113 is opened, the cold air formed by the cooling fan can enter the accommodating cavity 110 through the second air inlet 113.

Referring to fig. 3 and 4, the first air inlet 111 is closed, and the second air inlet 113 and the air mixing fan 300 are opened. After the cold air flows into the accommodating chamber 110 from the second air inlet 113, the cold air is immediately guided to the air delivery duct 120 by the air mixing fan 300. At the same time, the heat exchanged air flow is also guided to the air delivery duct 120 by the air mixing fan 300, so that the two air flows are mixed.

In the solution of the present embodiment, the second air inlet 113 is disposed in the accommodating cavity 110, and the second air inlet 113 is located on the air inlet side of the air mixing fan 300. When the air mixing is required, the first air inlet 111 may be closed, and the second air inlet 113 and the air mixing fan 300 may be opened. The cold air enters the accommodating cavity 110 from the second air inlet 113, and the air mixing fan 300 guides the cold air entering from the second air inlet 113 to the air delivery duct 120 together with the air flow subjected to heat exchange.

Thus, on the basis of achieving the mixing, both airflows are caused to pass through the air mixing fan 300. So that the two airflows are disturbed by the air mixing fan 300, which is helpful to improve the mixing effect of the two airflows. And when the difference between the cold air temperature and the set storage temperature is smaller, and air mixing is not needed, the first air inlet 111 can be opened, the second air inlet 113 and the air mixing fan 300 can be closed, and normal air supply is realized.

As shown in FIG. 5, in one embodiment, the top of the storage article 200 is provided with a plurality of wind deflectors 121. The plurality of wind deflectors 121 are distributed in the front-rear direction of the article 200. One of the adjacent two wind deflectors 121 extends rightward from the left side wall of the air delivery duct 120, and the other extends leftward from the right side wall of the air delivery duct 120.

Referring to fig. 5, in particular, three wind deflectors 121 are provided at the top of the storage object 200, that is, three wind deflectors 121 are provided in the air delivery duct 120. The three wind deflectors 121 are distributed in the front-rear direction. The first wind deflector 121 extends rightward from the left side wall of the air delivery duct 120 from the rear to the front, and is spaced apart from the right side wall of the air delivery duct 120. The second wind deflector 121 extends leftward from the right side wall of the air delivery duct 120 and is spaced apart from the left side wall of the air delivery duct 120. The third air deflector 121 extends rightward from the left side wall of the air delivery duct 120 and is spaced apart from the right side wall of the air delivery duct 120.

In the solution of the present embodiment, by providing a plurality of wind deflectors 121 on the top of the storage object 200, after the air flow enters the air delivery duct 120. Referring to the arrow direction in fig. 6, the air flow is guided by the wind deflector 121, and a flow path is formed to circulate back and forth from left to right and from right to left while flowing forward. Thereby making the flow path of the air flow in the air delivery duct 120 more tortuous and thus increasing the flow time of the air flow in the air delivery duct 120. So that the two airflows are more thoroughly mixed in the delivery duct 120.

The left-right extending direction of the wind deflector 121 may be perpendicular to the front-rear direction or may have a certain inclination. In addition, the number of the wind deflectors 121 may be two, three, four, five or more.

As shown in FIG. 6, in one embodiment, the top of the storage article 200 is provided with a plurality of air deflectors 122. The plurality of air deflectors 122 are distributed along the left-right direction of the storage piece 200, and the plurality of air deflectors 122 extend along the front-rear direction of the storage piece 200. Specifically, a plurality of air deflectors 122 are spaced apart from each other so that an air path is formed between two adjacent air deflectors 122. Thereby partitioning a plurality of air passages in the front-rear direction in the air delivery duct 120.

In the solution of this embodiment, the plurality of air deflectors 122 are disposed at the top of the storage object 200, so that the air flow entering the air delivery duct 120 can be dispersed into a plurality of air paths, and the air flow can be more uniform after flowing out of the air delivery duct 120, so that the refrigerating effect of the accommodating cavity 110 is more uniform.

The wind deflector 121 and the wind deflector 122 may be provided in the air delivery duct 120.

Meanwhile, in the case that the storage article 200 is a drawer, the magnetic field generating member 400 is disposed at the top of the storage article 200 to be used as a shielding member to form the air delivery duct 120, and the structure is simplified.
