Description

Technical Field

[0001] The invention relates to the technical field of refrigerators, and in particular to a refrigeration device of a built-in refrigerator and a built-in refrigerator. Background Art

[0002] With the application of refrigerators in life, refrigerators not only improve the preservation level of kitchen food, but also improve the quality of life. At the same time, with the development of the economy, people's demand for the capacity of refrigerators is increasing, and the experience of using refrigerators is also increasing. At present, embedded refrigerators are becoming more and more popular in the market. Embedded refrigerators can be embedded in cabinets, making the cabinets and refrigerators more beautiful and simple as a whole. However, at the same time, the heat dissipation of embedded refrigerators is also a pain point in research and development. At present, refrigerators in the prior art generally use natural convection heat dissipation, mainly relying on condensers on both sides or back of the refrigerator for heat dissipation. However, after the refrigerator is embedded, the gap between the left and right side panels and the back and the cabinet or wall becomes smaller and closed, and the heat on both sides and / or the back of the refrigerator cannot be transferred out, resulting in an increase in the air temperature near the side panels of the refrigerator, and the corresponding heat exchange temperature difference between the condenser and the external environment becomes smaller. The heat dissipated by the condenser cannot be effectively transferred outward, resulting in poor heat dissipation of the condenser, affecting the performance of the refrigerator, and in extreme cases, it may cause damage to the refrigerator. At the same time, when the user uses the refrigerator, when opening the refrigeration door to take items, it may cause a large change in the temperature difference of the refrigeration room, resulting in a short storage period of the physical objects stored in the refrigeration compartment and a high water loss rate.

[0003] Since the heat on the sides and / or the rear of the built-in refrigerator in the prior art cannot be transferred out, the air temperature near the side panels of the refrigerator increases, and the corresponding heat exchange temperature difference between the condenser and the external environment becomes smaller. The heat dissipated by the condenser cannot be effectively transferred to the outside, resulting in technical problems such as poor heat dissipation of the condenser and affecting the performance of the refrigerator. Therefore, the present invention studies and designs a refrigeration device for a built-in refrigerator and a built-in refrigerator. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that heat from the sides and / or rear of the built-in refrigerator cannot be transferred out, which affects the performance of the refrigerator, thereby providing a refrigeration device for a built-in refrigerator and a built-in refrigerator.

[0037] like Figure 1-3 As shown, the present invention provides a refrigeration device for a built-in refrigerator, which includes:

[0038] A compressor cabin 1, an air inlet channel 2, a return air channel 3 and a heat exchange area 4, wherein an atomizing device 5 is provided in the heat exchange area 4, and the atomizing device 5 can spray and cool the air in the heat exchange area 4, one end of the air inlet channel 2 is connected to the compressor cabin 1, and the other end is connected to the heat exchange area 4, so that the air in the compressor cabin 1 can be transported to the heat exchange area 4, one end of the return air channel 3 is connected to the compressor cabin 1, and the other end is connected to the heat exchange area 4, so that the air in the heat exchange area 4 cooled by the atomizing device 5 can be transported to the compressor cabin 1, and a compressor 6 and / or a condenser are provided in the compressor cabin 1.

[0039] The present invention provides an air inlet channel, an air return channel, a heat exchange area and an atomizing device, and the air inlet channel is connected to the heat exchange area and the compressor cabin, so that the hot air flow in the compressor cabin can be guided to the heat exchange area through the air inlet channel, and the atomizing device is provided in the heat exchange area, so that the area can be sprayed and humidified, thereby cooling the air flow, and the return air channel is connected to the heat exchange area and the compressor cabin, so that the air cooled by the atomizing device in the heat exchange area can be transported to the compressor cabin, so that the compressor and / or condenser in the compressor cabin can be effectively cooled. Since the heat on both sides and the rear of the refrigerator (especially the built-in refrigerator) usually comes from In the compressor cabin, the present invention can effectively cool down the compressor cabin through the above-mentioned inlet and return air channels, atomization device, and heat exchange area, so that the heat on the two sides and / or the rear of the built-in refrigerator can be effectively transferred out, effectively solving the problem that the heat on the two sides and / or the rear of the built-in refrigerator cannot be transferred out, resulting in affecting the performance of the refrigerator; and the present invention achieves cooling of the refrigerator by increasing the air circulation flow. Compared with the method of using a water heat exchanger to cool the air in the compressor cabin in the prior art, the required power consumption is small. Compared with the method of using spray cooling in the prior art, it can improve the cooling and heat dissipation effect, and at the same time the required power consumption is small (reduced power consumption).

[0040] In some embodiments,

[0041] The compressor chamber 1 , the air inlet channel 2 , the air return channel 3 and the heat exchange area 4 are cyclically connected to form a circulating air path.

[0042] This is a further preferred structural form of the present invention. Through the circular connection of the compressor cabin, the air inlet channel, the return air channel and the heat exchange area, a circulating air path can be formed, thereby forming a continuously circulating airflow between the compressor cabin and the heat exchange area of ​​the refrigerated compartment, which can further increase the effect of the air circulation flow, thereby further improving the cooling effect of the refrigerator compressor cabin, and further reducing the introduction of external airflow, avoiding external heat from affecting the heat exchange effect inside the refrigerator, while improving the cooling effect of the compressor cabin and further effectively reducing power consumption.

[0043] In some embodiments,

[0044] The heat exchange area 4 is arranged in the refrigerating compartment 8 of the built-in refrigerator, and the atomizing device 5 can also spray humidification and cooling to the area in the refrigerating compartment 8 except the heat exchange area 4 .

[0045] This is a further preferred structural form of the heat exchange area and the atomizing device of the present invention. The atomizing device can also be used to spray the area other than the heat exchange area of ​​the refrigerated compartment, which can cool down the interior of the refrigerated compartment and also have a moisturizing effect, effectively solving the problems of large temperature difference changes in the refrigerated compartment and short food storage cycle. The refrigerator atomizing device is reasonably used to improve the cooling effect of the refrigerated compartment and solve the problem of large temperature difference changes in the refrigerated compartment when the door is opened.

[0046] The present invention provides a device for cooling the compressor compartment of an embedded refrigerator and preserving food in a refrigerated compartment. The device is placed inside the refrigerated compartment. During use, the user adds water to the inside of the device, atomizes the inside, and moisturizes and preserves the food in the refrigerated compartment. The compressor compartment cooling device uses suction to the compressor compartment, an atomizing device inside the refrigerated compartment, and a cooling treatment of the refrigerated compartment. After atomization, the water reaches the compressor compartment through a circuit. In this way, part of the water is atomized to moisturize and preserve food, and the other part reaches the compressor compartment through relevant pipelines, forming an air path with the compressor compartment, so that the compressor compartment achieves the function of heat dissipation.

[0047] In some embodiments,

[0048] The inlet end of the atomizing device 5 is connected to a water inlet pipe, and the water in the water inlet pipe comes from at least one of condensed water of the evaporator of the built-in refrigerator, defrost water of the refrigerating compartment 8, defrost water of the freezing compartment of the built-in refrigerator, stored water or stored ice, and external water.

[0049] This is a preferred embodiment of the inlet water source of the atomizing device of the present invention, which can be obtained from the condensed water of the evaporator of the refrigerator, or from the defrosted water in the refrigerating compartment and / or freezing compartment of the refrigerator, or from the ice or water stored inside the refrigerator, as well as external water, all of which can be used to connect with the atomizing device to form a spray effect, thereby improving the cooling of the compressor compartment while also having a moisturizing effect on the refrigerating compartment, and having an effect of cooling and keeping the refrigerating compartment warm, preventing the situation where the door is opened and causing a large temperature difference. In addition, the rational use of water sources can also improve the utilization rate of resources and improve the energy efficiency of the refrigerator.

[0050] In some embodiments,

[0051] The air inlet channel 2 is an air inlet pipeline opened inside the built-in refrigerator, and the return air channel 3 is a return air pipeline opened inside the built-in refrigerator.

[0052] This is the preferred structural form of the air inlet and return air channels of the present invention, which can achieve effective communication of the airflow between the heat exchange area of ​​the refrigerated compartment and the compressor compartment through the structural form of pipelines, or through other structural forms, such as slots.

[0053] In some embodiments,

[0054] A first fan 9 is disposed in the press chamber 1 , and the first fan 9 can drive air flow in the press chamber 1 .

[0055] The present invention can drive the airflow to flow in the compressor compartment through the first fan in the compressor compartment, thereby improving the flow efficiency and flow performance of the airflow and enhancing the heat dissipation effect on the compressor compartment.

[0056] In some embodiments,

[0057] The air inlet channel 2 is provided with a second fan 10 , and the second fan 10 can drive the airflow in the compressor chamber 1 to flow to the heat exchange area 4 .

[0058] The present invention can drive the airflow from the compressor compartment to the heat exchange area through the second fan in the air inlet channel, thereby improving the flow efficiency and flow performance of the airflow and further enhancing the heat dissipation effect on the compressor compartment.

[0059] In some embodiments,

[0060] The return air channel 3 is provided with a third fan 11 , and the third fan 11 can drive the airflow in the heat exchange area 4 to flow to the compressor compartment 1 .

[0061] The present invention can drive the airflow from the heat exchange area to the compressor cabin through the third fan in the return air channel, introduce the air after spray humidification and cooling into the compressor cabin, improve the airflow efficiency and flow performance, and further enhance the heat dissipation effect on the compressor cabin.

[0062] In some embodiments,

[0063] A temperature sensor 12 is also provided inside the press cabin 1, and the temperature sensor 12 can detect the temperature inside the press cabin 1. When the first fan 9, the second fan 10 and the third fan 11 are included at the same time, and when the temperature inside the press cabin 1 is lower than the preset temperature, the second fan 10 and the third fan 11 are turned on at the same time, and the rotation speed of at least one of the first fan 9, the second fan 10 and the third fan 11 can be adjusted according to the temperature inside the press cabin 1.

[0064] The present invention can effectively detect the temperature inside the press cabin through the arrangement of a temperature sensor and multiple fans in cooperation with the temperature sensor, and control whether the three fans are working according to the temperature, and adjust the speed of the three fans to ensure the cooling and heat dissipation effect of the press cabin.

[0065] The specific implementation methods of the present invention are as follows: This proposal includes an atomization device (placed inside the refrigerator compartment), a first fan, a second fan, a third fan, a compressor compartment, a temperature sensor, an air inlet channel and a return air channel. During the normal operation of the refrigerator, the user adds water to the atomization device, and the atomization device is placed in the refrigerator compartment (the temperature inside the refrigerator compartment changes by 2-8°C). At this time, the air inlet channel and the return air channel are both in a closed state, and the atomization device works normally to moisturize and preserve the food in the refrigerator compartment. A temperature sensor is provided inside the compressor compartment. When the temperature of the temperature sensor reaches a preset critical value (if the temperature exceeds this preset temperature, the components inside the compressor compartment will be damaged. The performance of the refrigerator will also be reduced due to excessive temperature), the first fan and the second fan start to work, the air inlet channel is opened, and the first fan and the second fan are used to suck air from the compressor compartment. The atomization device performs air separation inside, and a part of the water is atomized to exchange heat with the hot air sucked out from the air inlet, so as to achieve the effect of cooling the hot air in the air inlet. At this time, the return air path is opened, and the third fan starts to suck air, and the atomized water and the cooled air are transferred to the compressor compartment through the rotation of the third fan and the return air path, so as to form an air path circulation, take away the heat inside the compressor compartment, and play a role in cooling the compressor compartment until the temperature inside the compressor compartment reaches below the preset value. At this time, the fan and the air inlet and return air paths are in a closed state, and the cycle is repeated. The device in this proposal is used to achieve the moisturizing and fresh-keeping of the food in the refrigerated compartment and the cooling of the compressor compartment.

[0066] The present invention also provides a built-in refrigerator, which comprises the refrigeration device of the built-in refrigerator.

[0067] The present invention sucks air from the compressor storage compartment of the built-in refrigerator and atomizes water installed in the cold storage compartment. After the water is atomized, the atomized water cools the airflow, and a part of the airflow after the cooling is sucked from the compressor compartment and returns the air, thereby forming an air path, thereby achieving the effect of cooling the compressor compartment. The other part of the airflow after the cooling is used for moisturizing and preserving the food in the cold storage compartment, and at the same time preventing the cold storage compartment from changing greatly due to the opening of the door.
