Abstract
Description
Technical Field
[0001] The present application relates to the technical field of refrigerators, and in particular to a balancing valve for a refrigerator and a refrigerator. Background Art
[0002] At present, most of the existing balancing valves used in refrigeration equipment use a one-way valve to connect the inside and outside of the refrigerator, and reduce the pressure difference between the inside and outside by letting in air when the door is opened, ultimately making the door opening easier. This one-way valve allows the airflow inside and outside the refrigerator to exchange, and the cold air in the refrigerator can also flow out when the door is not opened, resulting in energy waste; and because there is always an exchange of hot and cold air inside and outside the refrigerator, frost is prone to occur at the exchange point of hot and cold air in the one-way valve, and as the use time increases, the one-way valve hole is prone to frost blockage.
[0003] Related art discloses a balancing valve and a refrigerator for refrigeration equipment. The balancing valve includes: a valve body, which defines an airflow channel, and the two ends of the airflow channel are respectively suitable for communicating with the inner tank and the compressor cabin of the refrigeration equipment; a first valve plate, which is located in the airflow channel and can move relative to the airflow channel under the action of the airflow flowing through the airflow channel to open or close the airflow channel; a second valve plate, which is located in the airflow channel, and along the flow direction of the airflow in the airflow channel, the first valve plate and the second valve plate are arranged in sequence, and the second valve plate can move relative to the airflow channel under the action of the airflow flowing through the airflow channel to open or close the airflow channel. The double valve plates are arranged in sequence in the airflow channel, and an air cavity is formed between the first valve plate and the second valve plate to isolate the air inside and outside the refrigerator, reduce frost, and prevent cold air leakage; the valve plate opens when the door is opened to reduce negative pressure. The refrigerator is also provided with a heating element, which abuts against the outer surface of the valve body and is located between the second valve plate and the frost storage box. By transferring heat to the balancing valve and defrosting the balancing valve, the frost phenomenon in the balancing valve can be effectively alleviated.
[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:
[0005] The related technology places the balancing valve obliquely between the refrigerator liner and the refrigerator compressor cabin, and sets a double valve plate in the balancing valve. There is an air cavity between the double valve plates, so that the high-temperature air in the compressor cabin and the low-temperature air in the refrigerator liner will not directly contact each other, so as to reduce frost blockage, and set a heating element to defrost the balancing valve to alleviate the frosting phenomenon. However, the setting of the heating element will increase the energy consumption of the refrigerator and increase the cost.
[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0040] At present, most of the existing balancing valves used in refrigeration equipment use a one-way valve to connect the inside and outside of the refrigerator, and reduce the pressure difference between the inside and outside by letting in air when the door is opened, ultimately making the door opening easier. This one-way valve allows the airflow inside and outside the refrigerator to exchange, and the cold air in the refrigerator can also flow out when the door is not opened, resulting in energy waste; and because there is always an exchange of hot and cold air inside and outside the refrigerator, frost is prone to occur at the exchange point of hot and cold air in the one-way valve, and as the use time increases, the one-way valve hole is prone to frost blockage.
[0041] Related art discloses a balancing valve and a refrigerator for refrigeration equipment. The balancing valve includes: a valve body, which defines an airflow channel, and the two ends of the airflow channel are respectively suitable for communicating with the inner tank and the compressor cabin of the refrigeration equipment; a first valve plate, which is located in the airflow channel and can move relative to the airflow channel under the action of the airflow flowing through the airflow channel to open or close the airflow channel; a second valve plate, which is located in the airflow channel, and along the flow direction of the airflow in the airflow channel, the first valve plate and the second valve plate are arranged in sequence, and the second valve plate can move relative to the airflow channel under the action of the airflow flowing through the airflow channel to open or close the airflow channel. The double valve plates are arranged in sequence in the airflow channel, and an air cavity is formed between the first valve plate and the second valve plate to isolate the air inside and outside the refrigerator, reduce frost, and prevent cold air leakage; the valve plate opens when the door is opened to reduce negative pressure. The refrigerator is also provided with a heating element, which abuts against the outer surface of the valve body and is located between the second valve plate and the frost storage box. By transferring heat to the balancing valve and defrosting the balancing valve, the frost phenomenon in the balancing valve can be effectively alleviated.
[0042] The related technology places the balancing valve obliquely between the refrigerator liner and the refrigerator compressor cabin, and sets a double valve plate in the balancing valve. There is an air cavity between the double valve plates, so that the high-temperature air in the compressor cabin and the low-temperature air in the refrigerator liner will not directly contact each other, so as to reduce frost blockage, and set a heating element to defrost the balancing valve to alleviate the frosting phenomenon. However, the setting of the heating element will increase the energy consumption of the refrigerator and increase the cost.
[0043] Combination Figure 1-5 As shown, an embodiment of the present disclosure provides a balancing valve for a refrigerator, comprising a ventilation device 1, an atomization device 2 and a spray device 3.
[0044] like Figure 1-3 As shown, the ventilation device 1 includes a first end 11 and a second end 12, the first end 11 faces the outside of the refrigerator, and the second end 12 faces the inside of the refrigerator, so as to connect the inside of the refrigerator with the outside; the atomizing device 2 is arranged in the ventilation device 1 and the distance between the atomizing device 2 and the first end 11 is greater than the distance between the atomizing device 2 and the second end 12, so as to atomize the water droplets gathered in the ventilation device 1; the spraying device 3 is arranged in the ventilation device 1, one end of which faces the atomizing device 2, and the other end of which faces the inside of the refrigerator, so as to spray the atomized water droplets into the inside of the refrigerator.
[0045] By using the balancing valve for a refrigerator provided by the embodiment of the present disclosure, when the air pressure inside the refrigerator is lower than the air pressure outside the refrigerator, the air outside the refrigerator enters the ventilation device 1. The temperature at the end of the ventilation device 1 close to the inside of the refrigerator is lower, which will cause part of the water vapor entering the end of the ventilation device 1 close to the inside of the refrigerator to be liquefied, and the liquefied water droplets are atomized by the atomizing device 2. The atomized water droplets enter the spraying device 3 to be sprayed into the inside of the refrigerator, thereby avoiding local condensation in the ventilation device 1, balancing the air pressure inside and outside the refrigerator, and increasing the humidity inside the refrigerator, which has a certain degree of preservation effect on the food stored inside.
[0046] Alternatively, if Figure 4 As shown, the ventilation device 1 includes an air inlet section 13 , an air outlet section 14 and a connecting section 15 . The air inlet section 13 is arranged at the first end 11 ; the air outlet section 14 is arranged at the second end 12 ; and the connecting section 15 is arranged between the air inlet section 13 and the air outlet section 14 .
[0047] When the user opens the door to take something and then closes the door, the air temperature inside the refrigerator decreases and the volume shrinks, making the air pressure inside the refrigerator lower than the air pressure outside the refrigerator. The air outside the refrigerator enters the ventilation device 1 through the air inlet section 13 and reaches the connecting section 15. The temperature at the end of the connecting section 15 close to the inside of the refrigerator is relatively low, which will cause part of the water vapor at the end of the connecting section 15 close to the inside of the refrigerator to liquefy into water droplets. The liquefied water droplets are atomized by the atomizing device 2, and the atomized water droplets enter the spray device 3, which is sprayed into the inside of the refrigerator through the air outlet section 14 by the spray device 3, thereby preventing condensation of the air entering from the outside of the refrigerator in the connecting section 15 and preventing frost in the air outlet section 14.
[0048] Alternatively, if Figure 4 As shown, the air inlet section 13 includes a first air inlet 131 and a first air outlet 132 , the first air inlet 131 faces the outside of the refrigerator, the first air outlet 132 is connected to the connecting section 15 , and the area of the first air inlet 131 is larger than the area of the first air outlet 132 .
[0049] When air outside the refrigerator enters the ventilation device 1, the first air inlet 131 faces the outside of the refrigerator, and the air enters the air inlet section 13 through the first air inlet 131. The first air outlet 132 is connected to the connecting section 15, and the air leaves the air inlet section 13 through the first air outlet 132 and enters the connecting section 15. The area of the first air inlet 131 is larger than the area of the first air outlet 132, which is conducive to the entry of air into the ventilation device 1, and helps to solve the problem of condensation and frost inside the ventilation device 1 or inside the refrigerator.
[0050] Alternatively, if Figure 3 As shown, the air outlet section 14 includes a second air inlet 141 and a second air outlet 142 , the second air inlet 141 is connected to the connecting section 15 , the second air outlet 142 faces the inside of the refrigerator, and the area of the second air outlet 142 is larger than that of the second air inlet 141 .
[0051] When the air outside the refrigerator enters the ventilation device 1, the air enters the air inlet section 13 through the first air inlet 131, leaves the air inlet section 13 through the first air outlet 132, and enters the connecting section 15. The atomizing device 2 and the spraying device 3 are arranged in the connecting section 15. The air is liquefied and then atomized by the atomizing device 2. The atomized water droplets are sprayed toward the air outlet section 14 by the spraying device 3. The second air inlet 141 is connected to the connecting section 15. The atomized water droplets enter the air outlet section 14 through the second air inlet 141. The second air outlet 142 faces the inside of the refrigerator. The atomized water droplets leave the air outlet section 14 through the second air outlet 142 and are sprayed into the inside of the refrigerator.
[0052] Alternatively, if Figure 3 and Figure 4 As shown, the connecting section 15 includes a first section 151 and a second section 152. One end of the first section 151 is connected to the air inlet section 13; one end of the second section 152 is connected to the other end of the first section 151, and the other end is connected to the air outlet section 14. The atomizing device 2 is arranged in the second section 152, and the cross-sectional area of the first section 151 is smaller than the cross-sectional area of the second section 152.
[0053] One end of the first section 151 is connected to the air inlet section 13, and the air outside the refrigerator enters the first section 151 from the air inlet section 13. One end of the second section 152 is connected to the other end of the first section 151, and the air enters the second section 152 from the first section 151. The cross-sectional area of the first section 151 is smaller than the cross-sectional area of the second section 152. When the air enters the second section 152 from the first section 151, the cross-sectional area changes from small to large, and the air flow rate decreases, which is conducive to the liquefaction of air into water droplets in the second section 152, and avoids the frosting of air at the second air outlet 142 of the air outlet section 14. The atomizing device 2 is arranged in the second section 152. After the air is liquefied into water droplets in the second section 152, the water droplets are atomized by the atomizing device 2, and then the atomized water droplets are sprayed into the refrigerator through the spraying device 3.
[0054] Alternatively, if Figure 1 and Figure 4 As shown, the first section 151 is provided with a first bend 153 .
[0055] After the air outside the refrigerator enters the ventilation device 1, it flows in the ventilation device 1 and finally enters the inside of the refrigerator. The setting of the first bend 153 increases the flow path of the air in the ventilation device 1. Compared with no bend, the resistance encountered is greater, which is more conducive to the liquefaction of the air when it is cooled, and is more conducive to avoiding the frosting of the air at the second air outlet 142 of the air outlet section 14.
[0056] Alternatively, if Figure 3 As shown, the second section 152 includes a first sub-segment 154 and a second sub-segment 155. One end of the first sub-segment 154 is connected to the first section 151. One end of the second sub-segment 155 is connected to the first sub-segment 154 and a second bend 156 is formed at the connection, and the other end is connected to the air outlet section 14. The atomization device 2 and the spray device 3 are both arranged in the second sub-segment 155.
[0057] The air outside the refrigerator enters the first sub-segment 154 from the first section 151, and one end of the second sub-segment 155 is connected to the first sub-segment 154 and a second bend 156 is formed at the connection. The setting of the second bend 156 increases the flow path of the air in the ventilation device 1. Compared with no bend, the resistance encountered is greater, which is more conducive to the liquefaction of the air when it is cooled. The atomizing device 2 is arranged in the second sub-segment 155. After the air is liquefied into water droplets in the second sub-segment 155, the water droplets are atomized by the atomizing device 2. The other end of the second sub-segment 155 is connected to the air outlet section 14, and the spraying device 3 is also arranged in the second sub-segment 155. The subsequent spraying device 3 sprays the atomized water droplets from the second sub-segment 155 to the air outlet section 14, and then sprays them into the interior of the refrigerator from the air outlet section 14, so as to avoid local condensation in the second section 152 and balance the air pressure inside and outside the refrigerator.
[0058] Alternatively, if Figure 3 and Figure 5As shown, the spray device 3 is provided with a spray channel 31, one end of the spray channel 31 is connected to the outside of the refrigerator, and the other end is connected to the inside of the refrigerator.
[0059] The air outside the refrigerator enters the ventilation device 1, and is cooled and liquefied when approaching the inside of the refrigerator. The liquefied water droplets are atomized by the atomizing device 2 and enter the spraying device 3. The spraying device 3 rotates at a high speed, and the atomized water droplets are sprayed into the inside of the refrigerator along the spray channel 31.
[0060] Alternatively, if Figure 3 and Figure 5 As shown, the spray channel 31 is provided on the outer surface of the spray device 3 and extends spirally in a direction toward the interior of the refrigerator.
[0061] The atomized water droplets enter the spray device 3, and the spray device 3 rotates at a high speed. The atomized water droplets flow along the spray channel 31 on the outer surface of the spray device 3, and are thrown out of the spray channel 31 by the centrifugal force of the high-speed rotation of the spray device 3. The spray channel 31 extends in a spiral direction toward the inside of the refrigerator, that is, it extends in a spiral direction toward the movement of the water droplets. The spirally arranged spray channel 31 makes it easier for the atomized water droplets to be thrown out of the spray device 3 when rotating at a high speed and sprayed into the inside of the refrigerator.
[0062] Alternatively, if Figure 5 As shown, there are multiple spray channels 31 , and the multiple spray channels 31 are evenly distributed on the outer surface of the spray device 3 .
[0063] The air outside the refrigerator enters the ventilation device 1, and is cooled and liquefied when approaching the inside of the refrigerator. The liquefied water droplets are atomized by the atomizing device 2 and enter the spray device 3. A plurality of spray channels 31 are evenly distributed on the outer surface of the spray device 3. The spray device 3 rotates at a high speed, and the atomized water droplets are sprayed into the inside of the refrigerator along the plurality of spray channels 31. The evenly distributed arrangement of the plurality of spray channels 31 makes the spraying of the spray device 3 more even, which can increase the humidity inside the refrigerator and keep the food stored inside fresh to a certain extent.
[0064] Optionally, the balancing valve for the refrigerator further includes a controller, which is connected to the atomizing device 2 and is used to control the opening and closing of the atomizing device 2 .
[0065] The atomization device 2 is a piezoelectric vibrating plate. Under the action of the piezoelectric effect, the piezoelectric vibrating plate vibrates and emits ultrasonic waves in the liquid. When the ultrasonic waves are transmitted to the interface between the liquid and the air, due to the huge difference in the acoustic impedance of different media, the ultrasonic energy will quickly gather at the interface and eventually tear the liquid into tiny droplets to form atomization.
[0066] It can be understood that the balancing valve used in the refrigerator can be arranged on the refrigerator door or on the refrigerator body.
