Detailed Description
Fig. 1 is a schematic block diagram of a refrigerator 10 according to one embodiment of the present invention. The refrigerator 10 may generally include a cabinet 200, a duct partition 300, and a duct adjusting device 600.
The cabinet 200 has a storage compartment 210 and an air duct communicating with the storage compartment 210. For example, the air supply duct may communicate with the storage compartment 210 through the air supply opening 211 and the air return opening 212. The air flowing through the air supply duct may flow into the storage compartment 210 through the air supply outlet 211 and flow out of the storage compartment 210 through the air return outlet 212.
Fig. 2 is a schematic structural view of a refrigerator 10 according to one embodiment of the present invention. The air duct partition device 300 is disposed in the air supply duct, and partitions the air supply duct into a first sub-air duct 221 for circulating the first heat exchange air flow and a second sub-air duct 222 for circulating the second heat exchange air flow. The temperature of the first heat exchange gas stream is different from the temperature of the second heat exchange gas stream. For example, the temperature of the first heat exchange gas stream may be lower than the temperature of the second heat exchange gas stream. The first sub-air duct 221 is used for circulating a first heat-exchange air flow, which means that the first heat-exchange air flow can flow through the first sub-air duct 221 and flow into the storage compartment 210. The second sub-air duct 222 is used for circulating a second heat-exchange air flow, which means that the second heat-exchange air flow can flow through the second sub-air duct 222 and flow into the storage compartment 210.
The air duct adjusting device 600 is disposed in the air supply duct and is used for controllably opening and closing the first sub-air duct 221 and the second sub-air duct 222, so that the storage compartment 210 receives the first heat exchange air flow or the second heat exchange air flow. That is, the air duct adjusting device 600 is used to control the storage compartment 210 to selectively communicate with a certain sub-air duct, so as to deliver the corresponding heat exchange air flow to the storage compartment 210 by using the communicated sub-air duct.
In the refrigerator 10 of this embodiment, the air duct separating device 300 separates the air supply duct into the first sub-air duct 221 for circulating the first heat-exchange air flow and the second sub-air duct 222 for circulating the second heat-exchange air flow, and the air duct adjusting device 600 switches the first sub-air duct 221 and the second sub-air duct 222, so that the storage compartment 210 selectively receives the first heat-exchange air flow or the second heat-exchange air flow, and the refrigerator 10 can adjust the temperature of the storage compartment 210 by using the first heat-exchange air flow or the second heat-exchange air flow. The present embodiment provides a refrigerator 10 having a unique air duct structure and easy to implement variable temperature storage by improving the air duct structure of the refrigerator 10.
In some optional embodiments, the refrigerator 10 may further include a control device 100, which is in data connection with the air duct adjusting device 600 and is used for controlling the air duct adjusting device 600 to open and close the first sub air duct 221 and the second sub air duct 222 according to the set temperature of the storage compartment 210. The control device 100 may be a main control panel of the refrigerator 10. The set temperature of the storage compartment 210 is the fresh-keeping temperature to be reached by the storage compartment 210, and can be set by a user according to the fresh-keeping requirement of the articles.
The control device 100 is configured to communicate the first sub-air duct 221 and shut off the second sub-air duct 222 when the set temperature is lower than a preset first temperature threshold, and is further configured to communicate the second sub-air duct 222 and shut off the first sub-air duct 221 when the set temperature is higher than a preset second temperature threshold, where the first temperature threshold is smaller than the second temperature threshold
The first temperature threshold and the second temperature threshold may be set according to the freshness requirement of the storage compartment 210. For example, the first temperature threshold may be 5 ℃, the second temperature threshold may be 6 ℃, if the set temperature of the storage compartment 210 is 0 to 5 ℃, the air duct adjusting device 600 may communicate the first sub air duct 221 and shut off the second sub air duct 222, and if the set temperature of the storage compartment 210 is 6 to 10 ℃, the air duct adjusting device 600 may open the second sub air duct 222 and shut off the first sub air duct 221.
In this embodiment, the air duct separating device 300 and the air duct adjusting device 600 are arranged in the refrigerator 10, and the control device 100 controls the air duct adjusting device 600 to open and close the first sub air duct 221 and the second sub air duct 222 according to the set temperature of the storage compartment 210, so that the heat exchange air flow supplied to the storage compartment 210 can be switched, the storage compartment 210 changes the storage temperature, and the refrigerator has the advantages of simple structure and simple control process, and the refrigerator 10 can optimize the fresh-keeping level by using a simple structure.
In some embodiments, the refrigerator 10 may further include a temperature sensor 900 disposed in the storage compartment 210 for detecting the temperature inside the storage compartment 210. The refrigerator 10 can also control the air duct adjusting device 600 to open and close the first sub air duct 221 and the second sub air duct 222 according to the actual temperature of the storage compartment 210. For example, when the actual temperature of the storage compartment 210 exceeds a preset high-temperature threshold, the first sub-duct 221 may be connected and the second sub-duct 222 may be disconnected, and when the actual temperature of the storage compartment 210 is lower than a preset low-temperature threshold, the second sub-duct 222 may be connected and the first sub-duct 221 may be disconnected, so that the temperature of the storage compartment 210 may be rapidly restored to a preset level.
In some further embodiments, the refrigerator 10 may further include a cold providing device 800 and a heat providing device 500.
The cold providing device 800 is disposed in the first sub-air duct 221 or in airflow communication with the first sub-air duct 221, and is configured to provide cold to the first sub-air duct 221 to form a first heat exchange airflow. In this embodiment, the cold providing device 800 is used as a cold source for the first heat exchange air stream, so that the first heat exchange air stream forms a low temperature air stream. The air flow communication here means that the air flow flowing through the refrigeration providing apparatus 800 can flow into the first sub-duct 221.
The heat providing device 500 is disposed in the second sub-air duct 222 or in airflow communication with the second sub-air duct 222, and is configured to provide heat to the second sub-air duct 222 to form a second heat exchange airflow. In this embodiment, the heat providing device 500 is used as a heat source for the second heat-exchange airflow, so that the second heat-exchange airflow forms a high-temperature airflow. The air flow communication here means that the air flow passing through the heat providing device 500 can flow into the second sub-air duct 222.
The above "high temperature" and "low temperature" are relative terms and are intended to indicate that the temperature of the second heat exchange gas stream is higher than the temperature of the first heat exchange gas stream.
In this embodiment, the refrigerator 10 may further include a refrigeration system including a compressor, a condenser, an evaporator 800, and a throttling device. The coldness providing apparatus 800 may be an evaporator 800 of the refrigerator 10. The temperature of the evaporator 800, and thus the temperature of the first heat exchange air stream, can be adjusted by adjusting parameters such as the refrigerant flow rate of the refrigeration system and the operating frequency of the compressor.
The heat supplying device 500 is particularly added to the present embodiment because the temperature adjusting range of the evaporator 800 is limited. The heat supplying means 500 may be an electric heating means such as a heating body of an electric heating wire, an electric heating sheet, or the like.
The refrigerator 10 of the embodiment uses the electric heating device to provide heat to the storage compartment 210, so that the temperature of the storage compartment 210 can be controlled within a higher temperature range, and the refrigerator has the advantages of simple structure and simple control process. For example, the electric heating device may be directly disposed in the second sub-air duct 222.
The air duct adjusting device 600 may be a damper, and is controlled to be openably and closably disposed at the air outlet end of the first sub-air duct 221 and the air outlet end of the second sub-air duct 222 to open and close the first sub-air duct 221 and the second sub-air duct 222. The air outlet end of the first sub-air duct 221 may refer to a portion through which the airflow flows out of the first sub-air duct 221. The air outlet end of the second sub-air duct 222 may refer to a portion through which the airflow flows when flowing out of the second sub-air duct 222.
The number of the dampers of this embodiment is two, and the dampers are a first damper 610 and a second damper 620, respectively, wherein the first damper 610 is disposed at the air outlet end of the first sub-air duct 221, and the second damper 620 is disposed at the air outlet end of the second sub-air duct 222.
The air outlet end of the first sub-air duct 221 is opened and closed by the first air door 610, and the air outlet end of the second sub-air duct 222 is opened and closed by the second air door 620, so that the first sub-air duct 221 and the second sub-air duct 222 are opened and closed, and the air supply mode of the storage compartment 210 can be flexibly adjusted.
The storage compartment 210 is opened with an air supply outlet 211 to allow the first and second heat-exchanged air flows to flow into the inner space of the storage compartment 210.
The box 200 further has a connecting section 230 formed therein for connecting the air outlet 211 with the air outlet end of the first sub-duct 221 and the air outlet end of the second sub-duct 222. That is, the connection section 230 communicates the air outlet 211 with the air outlet end of the first sub-duct 221, and communicates the air outlet 211 with the air outlet end of the second sub-duct 222. That is, the connection section 230 is located on a common airflow path from the air outlet end of the first sub-duct 221 to the air outlet 211, and from the air outlet end of the second sub-duct 222 to the air outlet 211. Both the first heat-exchange air flow flowing out of the first sub-air duct 221 and the second heat-exchange air flow flowing out of the second sub-air duct 222 can flow into the air blowing opening 211 through the connecting section 230, so as to enter the inner space of the storage compartment 210. The supply air outlet 211 of this embodiment may be located at a bottom section of the storage compartment 210. The air outlet end of the first sub-duct 221 and the air outlet end of the second sub-duct 222 are higher than the air outlet 211.
The refrigerator 10 may further include a blower fan 700 disposed in the connection section 230 for inducing an airflow passing through the first sub-duct 221 and/or the second sub-duct 222 and then passing through the blower outlet 211. For example, when the first damper 610 is opened, the supply fan 700 may cause the first heat-exchanged air to flow through the first sub-duct 221, the connection section 230, and the supply outlet 211 in sequence, and enter the storage compartment 210. When the second damper 620 is opened, the supply fan 700 may cause the second heat-exchange airflow to sequentially flow through the second sub-duct 222, the connection section 230, and the supply outlet 211, and enter the storage compartment 210. The direction of the arrows in fig. 2 shows the direction of the airflow.
By additionally arranging the air supply fan 700 in the connecting section 230, the flow rate of the first heat exchange air flow and the second heat exchange air flow can be increased, so that the temperature regulation rate of the storage compartment 210 is increased.
The air supply fan 700 is disposed on a common airflow path from the air outlet end of the first sub-air duct 221 to the air inlet 211 and from the air outlet end of the second sub-air duct 222 to the air inlet 211, and the air supply fan 700 can be used to guide the first heat exchange airflow and the second heat exchange airflow at the same time, so as to implement the sharing of the air supply fan 700, which is beneficial to simplifying the structure of the refrigerator 10.
The air supply duct of the present embodiment is located at the rear side of the storage compartment 210. Here, directional terms such as "front" and "rear" are used with respect to the actual usage state of the refrigerator 10.
The air duct partition device 300 may be plate-shaped and extend along a vertical plane, so that the separated first sub air duct 221 and the second sub air duct 222 are arranged in parallel in the front-rear direction. For example, the duct divider 300 may be a flat plate extending along a vertical plane. In some embodiments, the rear wall of the storage compartment 210 may extend along a vertical plane, and the duct partition 300 may be parallel to the rear wall of the storage compartment 210.
The refrigerator 10 of the present embodiment uses the specially designed air duct separating device 300 to separate the first sub-air duct 221 and the second sub-air duct 222, and has a compact structure and a low manufacturing cost.
For example, the first sub-duct 221 may be located at a rear side of the second sub-duct 222. That is, the first sub air passage 221, the second sub air passage 222, and the storage compartment 210 are sequentially arranged from back to front in the front-rear direction of the refrigerator 10. The heat exchange cavity 250 for installing the evaporator 800 is further formed inside the box 200, and the heat exchange cavity 250 is located at the rear side of the air supply duct and is adjacent to the first sub-duct 221, so that the flow path of the first heat exchange air flow is conveniently shortened, and the loss of cold energy is reduced.
The evaporator 800 is disposed in the heat exchange chamber 250. And the heat exchange cavity 250 is communicated with the first sub-air channel 221 through the heat exchange port 251, so that the heat exchange air flowing through the evaporator 800 can enter the first sub-air channel 221 through the heat exchange port 251, thereby forming a first heat exchange air flow in the first sub-air channel 221. In some embodiments, a heat exchange fan 400 may be disposed in the heat exchange cavity 250 for inducing a heat exchange airflow flowing through the evaporator 800 and flowing to the heat exchange port 251 in the heat exchange cavity 250.
In alternative embodiments, the number of dampers may be changed to one. Fig. 3 is a schematic structural view of a refrigerator 10 according to another embodiment of the present invention.
