Description

Technical Field

[0001] The present application relates to the field of refrigeration technology, for example, to a refrigerator. Background Art

[0002] There are currently refrigerators with two storage compartments, such as a freezer compartment and a refrigerated compartment. The freezer compartment is provided with a freezer door for opening or closing the freezer space, and the refrigerated compartment is provided with a refrigerated door for opening or closing the refrigerated compartment. There is a center beam between the freezer door and the refrigerated door. The center beam is located at the door gap between the two door bodies. Compared with the foaming structure of the door body and the box body, the door seals of the two door bodies have poor insulation, and the temperature here is low. Because the center beam is located between the two door bodies, the gap is small and the air circulation is poor. Therefore, condensation or frost will form in the gap between the two door bodies, that is, condensation or frost will form at the center beam. Condensation and frost at the center beam will affect the normal use of the refrigerator, leading to user complaints.

[0003] 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:

[0004] The prior art uses a method of setting a heating wire at the center beam to remove condensation or defrost the center beam, which can solve the problem of frosting on the center beam or condensation near the center beam. However, since the heat is only concentrated near the surface of the center beam and the air cannot circulate at the center beam, this defrosting method can only remove condensation or defrost the surface of the center beam, but cannot solve the condensation or frost layer on the door body far from the center beam. In addition, this defrosting method requires the layout of a long line inside the box and inside the center beam. If strong electricity is used, the safety risk is high, and if weak electricity is used, the cost is high.

[0005] 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.

The defrosting air inlet 51 is arranged in the compressor compartment 1, and the defrosting air outlet is arranged in the center beam 4, so as to guide the hot air in the compressor compartment 1 to the center beam 4.

[0045] It is understandable that the refrigerator provided in the embodiment of the present disclosure is a refrigerator that uses a refrigerant cycle to cool each storage compartment. The refrigerant cycle flow path is composed of a compressor, an evaporator, and a condenser, and the evaporator is used to cool each storage compartment.

[0046] The refrigerator provided in the embodiment of the present disclosure may be an air-cooled refrigerator or a direct-cooled refrigerator, wherein the air-cooled refrigerator uses an air supply duct to deliver the cold energy of the evaporator to each storage compartment; the direct-cooled refrigerator directly uses the evaporator to cool each storage compartment.

[0047] The compressor and condenser in the refrigeration cycle are arranged in the compressor compartment 1, and during the refrigeration process, the compressor and condenser generate heat. The refrigerator provided in the embodiment of the present disclosure recovers the heat in the compressor compartment 1 through the air-inducing and defrosting pipeline 5, and guides the heat to the center beam 4 of the refrigerator to remove condensation or defrost the center beam 4.

[0048] Optionally, by setting the number, size or opening direction of the defrost air outlet, the first door body and / or the second door body of the refrigerator can be defrosted or decondensed while the center beam 4 is defrosted or decondensed. Optionally, the opening direction of the defrost air outlet is along the front-to-back direction of the center beam 4 to defrost or decondense the center beam 4, and the defrost air outlet also includes a defrost air outlet with an opening direction toward the first door body, and also includes a defrost air outlet with an opening direction toward the second door body to defrost or decondense the first door body and the second door body, respectively. Optionally, air doors are provided at different defrost air outlets to selectively open or close according to the needs of defrosting or decondensing the center beam 4, the first door body or the second door body.

[0049] Optionally, the first storage compartment 2 and the second storage compartment 3 are arranged side by side in a horizontal direction. Figure 1 As shown, the middle beam 4 is located between the first storage compartment 2 and the second storage compartment 3. For example, the storage space of the first storage compartment 2 is smaller than the storage space of the second storage compartment 3, and the first storage compartment 2 is a freezer compartment and the second storage compartment 3 is a refrigerator compartment.

[0050] Optionally, the compressor compartment 1 is arranged at the lower part of the first storage compartment 2. The defrosting air inlet 51 is arranged at the top of the compressor compartment 1.

[0051] The compressor compartment 1 is arranged at the lower part of the first storage compartment 2, so that the first storage compartment 2 and the compressor compartment 1 are arranged side by side. At this time, the air-inducing and defrosting pipeline 5 is arranged roughly vertically, and the heat in the compressor compartment 1 arranged at the bottom is guided upward to the middle beam 4 located at the upper part.

[0052] Optionally, the vertically arranged air-inducing and defrosting pipeline 5 is provided with at least one bent pipe portion, and the bent pipe portion is arranged outside the first storage compartment 2. Figure 1 In this way, the length of the air-inducing defrosting pipeline 5 is reduced, the heat loss of the compressor compartment 1 in the air-inducing defrosting pipeline 5 is reduced, and the utilization rate of the heat in the compressor compartment 1 is improved.

[0053] Optionally, the outside of the air-inducing defrost pipeline 5 is wrapped with a heat-insulating layer. In this way, the heat loss of the air-inducing defrost pipeline 5 during the heat-guiding process is further reduced, and at the same time, the noise of the air-inducing defrost pipeline 5 during the heat-transfer process is reduced. Optionally, the air-inducing defrost pipeline 5 includes a first pipe section close to the outside of the first storage compartment 2, wherein the heat-insulating layer is at least provided on the first pipe section of the air-inducing defrost pipeline 5. Optionally, the heat-insulating layer includes heat-insulating cotton.

[0054] Optionally, a hot air collecting expanding pipe is provided at the defrost air inlet 51, wherein the hot air collecting expanding pipe is provided on the upper part of the compressor or the condenser.

[0055] In the disclosed embodiment, a hot air collection expansion pipe, such as a trumpet-shaped expansion pipe, for collecting hot air is also provided at the defrost air inlet 51. In this way, the efficiency of heat collection in the compressor compartment 1 is improved. Optionally, the diameter of the opening of the hot air collection expansion pipe is greater than or equal to 5 times the diameter of the defrost air inlet 51.

[0056] Optionally, the aforementioned freezer further includes an induced draft fan, which is arranged at the defrost air inlet 51 of the induced draft defrost pipeline 5 .

[0057] An induced draft fan is provided at the defrost air inlet 51 of the induced draft defrost pipeline 5 to improve the induced draft efficiency of the hot air in the compressor compartment 1 .

[0058] Optionally, an air outlet fan is provided at the defrost air outlet of the air-inducing defrost pipeline 5 to improve the efficiency of defrosting or removing condensation of the center beam 4, the first door body or the second door body.

[0059] Optionally, the defrost air outlet includes a first defrost air outlet 52 and a second defrost air outlet 53 which are spaced apart along the center beam 4 , wherein a connecting pipeline is provided between the first defrost air outlet 52 and the second defrost air outlet 53 .

[0060] Along the front-to-back direction of the middle beam 4, a first defrost air outlet 52 and a second defrost air outlet 53 are arranged at intervals. Figure 2 As shown, the hot air is blown to the middle beam 4 more evenly. Optionally, the number of the first defrost air outlets 52 can be 3, and the 3 first defrost air outlets 52 are arranged horizontally. Optionally, the directions of the 3 first defrost air outlets 52 are different. The air outlet direction of a first defrost air outlet 52 close to the first door body is toward the first door body, the air outlet direction of a first defrost air outlet 52 close to the second door body is toward the second door body, and the first defrost air outlet 52 in the middle is toward the rear of the middle beam 4. Optionally, the number of the second defrost air outlets 53 can be 3, and the 3 second defrost air outlets 53 are arranged horizontally. Optionally, the three second defrost air outlets 53 have different directions, the outlet direction of the second defrost air outlet 53 close to the first door body is toward the first door body, the outlet direction of the second defrost air outlet 53 close to the second door body is toward the second door body, and the second defrost air outlet 53 in the middle is toward the rear of the middle beam 4. It can be understood that the end of the refrigerator close to the user is the front end, and the end away from the user is the rear end of the refrigerator.

[0061] The first defrost air outlet 52 is disposed at one end of the middle beam 4, and the second defrost air outlet 53 is disposed at the middle of the middle beam 4. For example, the first defrost air outlet 52 is disposed at the front end of the middle beam 4, and the second defrost air outlet 53 is disposed at the middle of the middle beam 4. Optionally, the distance between the first defrost air outlet 52 and the second defrost air outlet 53 is a first defrost distance, and the distance between the second defrost air outlet 53 and the rear end of the refrigerator is a second defrost distance, wherein the first defrost distance is equal to the second defrost distance.

[0062] Optionally, the aforementioned refrigerator further includes a semiconductor refrigeration element 6. The semiconductor refrigeration element 6 is arranged outside the first storage compartment 2, and the semiconductor refrigeration element 6 includes a hot end 61 and a cold end 62, wherein the hot end 61 of the semiconductor refrigeration element 6 is provided with a hot air compensation pipeline, a hot end fan is provided in the hot air compensation pipeline, and the hot air compensation pipeline is connected to the air induction and defrosting pipeline 5.

[0063] The principle of semiconductor refrigeration technology is to absorb and release heat through the potential energy change of electrons and holes in the energized circuit, so that the semiconductor refrigeration element can generate cold and heat, thereby realizing the functions of cooling and heating. Semiconductor refrigeration elements are characterized by small size, no pollution, no noise, and simple structure.

[0064] The working state of the refrigerator compressor is determined by the refrigeration demand of the first storage room 2 and the second storage room 3. When the ambient temperature is low and the temperatures of the first storage room 2 and the second storage room 3 are both near the set temperature, the compressor will be temporarily stopped or run at a low load. At this time, the heat generated by the compressor and condenser in the compressor compartment 1 is less. When the ambient humidity is high, the probability of condensation or frost on the center beam 4, the first door body or the second door body is high. At this time, the heat in the compressor compartment 1 alone is not enough to defrost or remove condensation on the center beam 4, the first door body or the second door body.

[0065] The refrigerator provided in the embodiment of the present disclosure further includes a semiconductor refrigeration element 6, and the hot end 61 of the semiconductor refrigeration element 6 is used as a temperature compensation device for the air-inducing and defrosting pipeline 5. When the compressor in the compressor compartment 1 is in a paused or low-frequency operation state, the heat generated by the hot end 61 is supplemented into the air-inducing and defrosting pipeline 5 through the hot air compensation pipeline by turning on the semiconductor refrigeration element 6, thereby improving the defrosting or decondensation effect of the air-inducing and defrosting pipeline 5 on the center beam 4, the first door body or the second door body when the compressor is paused or in low-frequency operation.

[0066] Optionally, the air-inducing defrosting pipeline 5 includes a first temperature compensation pipe section connected to the hot air compensation pipeline, wherein the first temperature compensation pipe section is provided with a conversion damper.

[0067] Optionally, the switching damper is controlled to be opened or closed according to the operating state of the compressor. For example, when the compressor is stopped or running at a low frequency, the switching damper is controlled to be opened, so that the heat generated by the hot end 61 of the semiconductor refrigeration element 6 enters the induced air defrost pipeline 5 through the hot air compensation pipeline, thereby increasing the hot air temperature at the defrost outlet. Optionally, the switching damper can also be controlled to be opened or closed according to the temperature in the induced air defrost pipeline 5. For example, when the temperature in the induced air defrost pipeline 5 is less than or equal to a temperature threshold, it is considered that the current temperature in the induced air defrost pipeline 5 is insufficient for defrosting or removing condensation. At this time, the switching damper is controlled to be opened, so that the heat generated by the hot end 61 of the semiconductor refrigeration element 6 enters the induced air defrost pipeline 5 through the hot air compensation pipeline, thereby increasing the hot air temperature at the defrost outlet.

[0068] Optionally, the aforementioned refrigerator further includes an air supply duct 21 to supply air to the first storage compartment 2. The cold end 62 of the semiconductor refrigeration element 6 is provided with a cold air compensation pipeline, a cold end fan is provided in the cold air compensation pipeline, and the cold air compensation pipeline is connected to the air supply duct 21.

[0069] The cold energy generated by the cold end 62 of the semiconductor refrigeration element 6 is used to perform temperature compensation on the first storage compartment 2, thereby improving the refrigeration effect on the first storage compartment 2. Optionally, the first storage compartment 2 is a freezer compartment.

[0070] Optionally, the air supply duct 21 includes an upper air outlet 211 and a lower air outlet 212 for supplying air to the first storage compartment 2, and the air supply duct 21 includes a second temperature compensation pipe section connected to the cold air compensation pipeline, wherein the second temperature compensation pipeline is arranged between the upper air outlet 211 and the lower air outlet 212.

[0071] When the user uses the first storage compartment 2 to store items, the storage of items will block the temperature in the first storage compartment 2, so that the temperature near the air outlet of the first storage compartment 2 is lower, while the temperature far from the air outlet is higher due to the shielding effect of the items. In this way, the temperature uniformity of the first storage compartment 2 is reduced, and the constant temperature storage effect of the first storage compartment 2 on the items is reduced.

[0072] In the refrigerator provided by the embodiment of the present disclosure, the air supply duct 21 includes an upper air outlet 211 and a lower air outlet 212 for supplying air to the first storage compartment 2, respectively, so as to supply air to the upper and lower parts of the first storage compartment 2, respectively, thereby improving the temperature uniformity of different positions in the entire first storage compartment 2. Furthermore, a second temperature compensation pipeline connected to the cold air compensation pipeline of the cold end 62 of the semiconductor refrigeration element 6 is arranged between the upper air outlet 211 and the lower air outlet 212, so that the cold energy generated by the semiconductor refrigeration element 6 can simultaneously compensate the cold energy of the air outlets of the upper air outlet 211 and the lower air outlet 212, thereby further improving the temperature uniformity of different positions in the first storage compartment 2.

[0073] The disclosed embodiment further provides a control method for the aforementioned air-inducing and defrosting pipeline 5 .

[0074] When the ambient temperature is high, the compressor startup rate is high. At this time, the compressor and condenser in the compressor compartment 1 generate more heat, and the air defrosting pipeline 5 has a better effect on the defrosting or decondensation of the center beam 4, the first door body or the second door body. However, when the ambient temperature is low, the temperature in the first storage compartment 2 and the second storage compartment 3 of the refrigerator may be close to the preset temperature. At this time, the compressor may be in a shutdown state or a low-frequency operation state, the compressor startup rate is low, and the heat generated in the compressor compartment 1 is small, which may not be enough to defrost the center beam 4, the first door body or the second door body.

[0075] In the control method provided by the embodiment of the present disclosure, when the startup rate of the compressor is low, the compressor is controlled to be forced to start frequently to increase the heat in the compressor compartment 1.

[0076] The ambient temperature or the start-up rate of the compressor is obtained. When the ambient temperature is less than or equal to 20° C., or the start-up rate of the compressor is less than or equal to 30%, it is detected whether the compressor is currently in a shutdown state.

[0077] Embodiment 1, when the compressor is in the shutdown state, the compressor is controlled to be forced to start, and the induced draft fan is controlled to start 1 minute later, and the heat in the compressor compartment 1 is guided to the center beam 4 through the induced draft defrosting pipeline 5. When the compressor is turned on for more than or equal to 3 minutes, or the temperature in the freezer compartment is less than or equal to the set temperature, the compressor is controlled to stop running, and the induced draft fan is controlled to stop 3 minutes later. Here, the duration of the compressor's single start-up is controlled, and when the condenser temperature rises, the compressor is controlled to stop running as soon as the refrigerant lowers the evaporator temperature, thereby achieving the purpose of controlling the compressor to start and stop frequently. In this way, while increasing the heat in the compressor compartment 1, it will not affect the temperature of the freezer compartment.

[0078] In Example 2, when the compressor is in the on state, it is determined whether the freezer compartment needs further refrigeration. If further refrigeration is needed, the semiconductor refrigeration element 6 is controlled to be turned on; if refrigeration is not needed, the induced draft fan is controlled to be turned on after 1 minute. When the temperature of the freezer compartment is less than or equal to the set temperature, the compressor is controlled to stop running, and the induced draft fan is controlled to stop after 3 minutes.

[0079] It can be seen that the control method for the air-inducing and defrosting pipeline 5 provided in the embodiment of the present disclosure increases the heat in the compressor compartment 1 without affecting the temperature of the refrigerated compartment or the frozen compartment by controlling the frequent start and stop of the compressor, thereby improving the defrosting effect of the air-inducing and defrosting pipeline 5 on the center beam 4, the first door body or the second door body.
