[0029] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] In the prior art, the treatment of condensed water mainly adopts the method of manually pouring out the water in the water tray or using the heat of the refrigeration system to evaporate the condensed water. However, the manual method requires manual pouring of water regularly, which is more troublesome. The solution of using the heat of the refrigeration system to heat and evaporate cannot meet the needs of evaporating a large amount of condensed water for large refrigerators or in high temperature and high humidity environments, resulting in condensed water overflow.

[0032] In view of the above problems, a refrigerator is provided in a preferred embodiment 1 of the present invention. Specifically, Figure 1 An optional structural schematic diagram of the refrigerator is shown, such as Figure 1 As shown, the refrigerator includes:

[0033] Refrigeration compartment 1; The cabinet body of the refrigerator defines a refrigeration compartment 1, in which a shelf 6 is provided and a cabinet door 13 is installed;

[0034] The refrigeration system comprises a compressor 14, an evaporator and a condenser 3 connected in sequence; wherein the evaporator is located above the refrigeration compartment 1;

[0035] like Figure 1 As shown, the evaporator is located above the interior of the refrigeration compartment 1 and is used to provide cold air to the refrigeration compartment 1 to achieve a refrigerated storage effect;

[0036] The evaporator water receiving tray 5 is located below the evaporator and is used to receive the condensed water generated by the evaporator;

[0037] The refrigerant pipe water receiving pan 8 is located below the refrigeration chamber 1 . The refrigerant pipe water receiving pan 8 is connected to the evaporator water receiving pan 5 and is used to receive condensed water discharged from the evaporator water receiving pan 5 . The exhaust pipe 12 of the compressor 14 passes through the refrigerant pipe water receiving pan 8 to heat the condensed water in the refrigerant pipe water receiving pan 8 .

[0038] In the above embodiment, a condensed water evaporation system for a refrigerator is provided, the system includes two condensed water receiving pans, one is an evaporator receiving pan, located below the evaporator, for receiving condensed water generated by the evaporator, and the other is a refrigerant pipe receiving pan, located below the refrigeration compartment, the refrigerant pipe receiving pan is connected to the evaporator receiving pan, for receiving condensed water discharged from the evaporator receiving pan, wherein the exhaust pipe of the compressor passes through the refrigerant pipe receiving pan to heat the condensed water in the refrigerant pipe receiving pan. In the prior art, a condensate receiving pan is usually used to receive the condensate. After the condensate receiving pan is full, it cannot be processed quickly and effectively. In the present invention, a water receiving pan is provided under the refrigerator, which can increase the amount of condensate received without occupying additional volume and affecting the layout of the refrigerator. The exhaust pipe is extended to the bottom water receiving pan to heat the condensate. When there is too much condensate, the system starts the exhaust pipe to heat the bottom water receiving pan, thereby increasing the temperature of the condensate in the bottom water receiving pan and accelerating the evaporation of the condensate, effectively solving the problem of condensate accumulation or overflow, and improving the condensate processing capacity of the refrigerator and the operating stability of the refrigerator in various environments, especially high temperature and high humidity environments.

[0039] In a preferred embodiment of the present invention, an evaporation paper is also provided in the refrigerant pipe water receiving tray 8, which is located in the refrigerant pipe water receiving tray 8 and is used to increase the evaporation area of ​​the condensed water; wherein the evaporation paper is a finned evaporation paper. The evaporation paper can increase the evaporation area of ​​the condensed water, and preferably a finned evaporation paper is used to further increase the evaporation area. The compressor exhaust pipe 12 and the evaporation absorbent paper are arranged in the bottom water receiving tray to increase the temperature of the bottom condensed water and its evaporation surface area. The dual measures increase the evaporation rate of the condensed water and further remove the condensed water.

[0040] Preferably, the refrigerator further comprises: a drain pipe, the water inlet end of the drain pipe is connected to the refrigerant pipe water receiving pan 8, and the water outlet end of the drain pipe is connected to the condenser 3, for passing the condensed water in the refrigerant pipe water receiving pan 8 to the condenser 3; a circulating water pump 10, located on the drain pipe, for conveying the condensed water in the drain pipe. Figure 1 As shown, when the condensed water cannot be evaporated by heating and evaporating the exhaust pipe 12 and the evaporating paper alone, the present invention can also adopt a third measure, that is, spraying the condensed water on the surface of the condenser 3, heating the condensed water through the fins and copper tubes of the condenser 3 and evaporating a part of the condensed water. Figure 1 As shown, the condenser 3 is located at the upper part of the refrigerator, and the refrigerant pipe water receiving tray 8 is located at the lower part of the refrigerator, so a circulating water pump 10 is used to transport the condensed water in the refrigerant pipe water receiving tray 8 to the condenser 3. In particular, when the amount of condensed water generated by heating through the exhaust pipe 12 and evaporation of the evaporation paper is greater than the amount of condensed water evaporated, the circulating water pump 10 is started to establish water circulation and spray on the surface of the condenser 3, and the condensed water is heated and evaporated by the waste heat of the condenser 3. A condensed water evaporation treatment system is formed by multiple means to ensure that no condensed water overflows under complex and harsh working conditions.

[0041] In another preferred embodiment of the present invention, in order to improve the evaporation effect of the condenser 3, the refrigerator further includes a water separator 2, which is located above the condenser 3, and the water outlet end of the drain pipe is connected to the water separator 2, and the water separator 2 is used to spray the condensed water in the drain pipe onto the condenser 3. By spraying, the contact area between the condensed water and the condenser 3 is increased, the evaporation rate of the condensed water is further increased, and the accumulation of condensed water is avoided.

[0042] like Figure 1 As shown, a condenser water receiving tray 4 is also provided below the condenser 3 to prevent excess condensed water from accumulating in the refrigeration system when the condenser 3 evaporates the condensed water.

[0043] In order to achieve the accuracy of condensed water evaporation control, the refrigerator of the present invention further includes: a liquid level sensor 7, located in the refrigerant pipe water receiving tray 8, for detecting the water level in the refrigerant pipe water receiving tray 8; a water temperature sensor 9, located in the refrigerant pipe water receiving tray 8, for detecting the water temperature in the refrigerant pipe water receiving tray 8. By controlling the evaporation of condensed water through water level and water temperature signals, the evaporation amount of condensed water can be accurately controlled, and corresponding evaporation control is implemented for condensed water of different magnitudes to achieve the best evaporation effect.

[0044] The present invention adopts an overhead compressor 14, such as Figure 1 As shown, the compressor 14 is located above the refrigeration compartment 1, so the exhaust pipe 12 of the compressor 14 is divided into a first exhaust branch and a second exhaust branch, the first exhaust branch is connected to the condenser 3, and the second exhaust branch passes through the refrigerant pipe water receiving pan 8 to heat the condensed water in the refrigerant pipe water receiving pan 8. The present invention leads the exhaust pipe 12 to the water receiving pan below, and can pass through the bottom of the refrigerant pipe water receiving pan 8 or the refrigerant pipe water receiving pan 8 to heat the condensed water in the refrigerant pipe water receiving pan 8.

[0045] like Figure 1 As shown, the present invention places the refrigerant pipe water receiving pan 8 at the bottom of the refrigerator, avoiding placing it on the top to affect the layout of the refrigeration system, or placing it on the back to affect the width of the refrigerator. Placing the refrigerant pipe water receiving pan 8 at the bottom does not affect the overall layout of the refrigeration system and the refrigerator, and a larger refrigerant pipe water receiving pan 8 can be set at the bottom to increase the water capacity. For commercial refrigerators that need to handle a large amount of condensed water, the problem of condensed water accumulation or overflow can be effectively solved. And a larger area of ​​the refrigerant pipe water receiving pan 8 can be set with a larger area of ​​evaporation paper to further increase the evaporation rate and improve the condensed water processing capacity of the refrigerator.

[0046] The refrigerator is composed of a refrigeration compartment 1, a water distributor 2, a condenser 3, a condenser water tray 4, an evaporator water tray 5, a liquid level sensor 7, a refrigerant pipe water tray 8, a circulating water pump 10, a fin evaporation paper 11, an exhaust pipe 12 and a control system thereof. The condensate treatment method is comprehensively controlled by the liquid level of the bottom water tray, and a condenser evaporation treatment system is formed by multiple means such as exhaust pipe heating, evaporation of evaporation paper, and condenser evaporation, so as to ensure that no condensate overflows under complex and harsh working conditions.

[0047] In a normal low temperature and low humidity environment, the exhaust pipe 12 heats the water inside the refrigerant pipe water tray 8, and the heated water is absorbed by the multi-layer evaporation paper to achieve condensed water heating and evaporation. At this time, since the refrigeration system produces less condensed water, it will not exceed the liquid level detected by the liquid level sensor 7, and the condensing fan operates according to the refrigeration demand control logic.

[0048] In a high temperature and high humidity environment, if there is a situation of frequent opening and closing of doors, a large amount of condensed water will be generated after the hot air entering through the cabinet door 13 contacts the evaporator. The single heating through the exhaust pipe 12 and the evaporation of the evaporating paper will result in a situation where the condensed water generated is greater than the evaporation amount, which will cause the liquid level in the refrigerant pipe water receiving tray 8 to rise to the detection position of the liquid level sensor 7, and the water temperature will drop. At this time, after the control system receives the high water level signal and the low water temperature signal, it starts the circulating water pump 10 to discharge the condensed water into the water distributor 2 and evenly spray it onto the condenser 3. The fins and copper tubes of the condenser 3 heat the condensed water and evaporate part of the condensed water until the water level and water temperature in the water receiving tray drop.

[0049] Example 2

[0050] In a preferred embodiment 2 of the present invention, a refrigerator control method is provided, which is applied to the refrigerator in the above embodiment 1. Specifically, Figure 2 An optional flow chart of the method is shown as follows: Figure 2 As shown, the method includes the following steps S202-S206:

[0051] S202: Detecting the water level and the water temperature in the refrigerant pipe water tray;

[0052] S204: Determine whether the water level and the water temperature in the refrigerant pipe water tray meet the preset evaporation conditions;

[0053] S206: Control the operation of the refrigerator according to the determination result.

[0054] In the above embodiment, a condensed water evaporation system for a refrigerator is provided, the system includes two condensed water receiving pans, one is an evaporator receiving pan, located below the evaporator, for receiving condensed water generated by the evaporator, and the other is a refrigerant pipe receiving pan, located below the refrigeration compartment, the refrigerant pipe receiving pan is connected to the evaporator receiving pan, for receiving condensed water discharged from the evaporator receiving pan, wherein the exhaust pipe of the compressor passes through the refrigerant pipe receiving pan to heat the condensed water in the refrigerant pipe receiving pan. In the prior art, a condensate receiving pan is usually used to receive the condensate. After the condensate receiving pan is full, it cannot be processed quickly and effectively. In the present invention, a water receiving pan is provided under the refrigerator, which can increase the amount of condensate received without occupying additional volume and affecting the layout of the refrigerator. The exhaust pipe is extended to the bottom water receiving pan to heat the condensate. When there is too much condensate, the system starts the exhaust pipe to heat the bottom water receiving pan, thereby increasing the temperature of the condensate in the bottom water receiving pan and accelerating the evaporation of the condensate, effectively solving the problem of condensate accumulation or overflow, and improving the condensate processing capacity of the refrigerator and the operating stability of the refrigerator in various environments, especially high temperature and high humidity environments.

[0055] In a preferred embodiment of the present invention, Figure 1 As shown, the liquid level sensor 7 is located in the refrigerant tube water pan 8 and is used to detect the water level in the refrigerant tube water pan 8; the water temperature sensor 9 is located in the refrigerant tube water pan 8 and is used to detect the water temperature in the refrigerant tube water pan 8. Judging whether the water level in the refrigerant tube water pan and the water temperature in the refrigerant tube water pan meet the preset evaporation conditions includes: judging whether the water level in the refrigerant tube water pan is greater than or equal to the preset water level and whether the water temperature in the refrigerant tube water pan is less than or equal to the preset water temperature; when the water level in the refrigerant tube water pan is greater than or equal to the preset water level and / or the water temperature in the refrigerant tube water pan is less than or equal to the preset water temperature, it is determined that the preset evaporation conditions are met, otherwise, it is determined that the preset evaporation conditions are not met. The water level in the refrigerant tube water pan and the water temperature in the refrigerant tube water pan can reflect the amount of condensed water. When the amount of condensed water increases, the water level rises or the water temperature decreases. Therefore, the subsequent condensed water control scheme is determined by the water level in the refrigerant tube water pan and the water temperature in the refrigerant tube water pan.

[0056] After determining the water level and the water temperature in the refrigerant pipe water tray, the operation of the refrigerator is controlled according to the judgment result, including: when the preset evaporation conditions are met, the circulating water pump and the water distributor are controlled to be turned on, and the condenser is operated in the water cooling mode; when the preset evaporation conditions are not met, the circulating water pump and the water distributor are controlled to be turned off, and the condenser is operated in the air cooling mode.

[0057] In a normal low temperature and low humidity environment, that is, when the preset evaporation conditions are not met, the exhaust pipe heats the condensed water inside the refrigerant pipe water tray, and the heated water is absorbed by the multi-layer evaporation paper to achieve condensed water heating and evaporation. At this time, since the refrigeration system produces less condensed water, it will not exceed the liquid level detected by the liquid level sensor, and the condensing fan operates according to the refrigeration demand control logic.

[0058] In a high temperature and high humidity environment, if there is a situation of frequent opening and closing of doors, a large amount of condensed water will be generated after the hot air entering through the cabinet door contacts the evaporator. The single heating through the exhaust pipe and evaporation of the evaporating paper will result in a situation where the condensed water generated is greater than the evaporation amount, which will cause the liquid level in the refrigerant pipe water tray to rise to the detection position of the liquid level sensor, and the water temperature will drop. At this time, after the control system receives the high water level signal and the low water temperature signal, it starts the circulating water pump to discharge the condensed water into the water distributor and evenly spray it on the condenser. The fins and copper tubes of the condenser heat the condensed water and evaporate part of the condensed water until the water level and water temperature in the water tray drop.

[0059] Preferably, after the condenser is operated in the water cooling mode, the method further includes: detecting the condensing temperature of the condenser; determining whether the condensing temperature is greater than a first preset condensing temperature; if so, controlling the condensing fan to start a high-speed operation mode; otherwise, controlling the condensing fan to start a low-speed operation mode, and when the condensing temperature is less than a second preset condensing temperature, controlling the condensing fan to shut down, wherein the first preset condensing temperature is greater than the second preset condensing temperature. When the condenser is operated in the water cooling mode, the condensing temperature is detected to determine whether the condensing fan is operated at a high speed or a low speed or stops operating, so as to ensure that there is enough condensing temperature to meet the demand for evaporation of condensed water.

[0060] Another refrigerator control method is provided in a preferred embodiment 2 of the present invention. Specifically, Figure 3 An optional flow chart of the method is shown as follows: Figure 3 As shown, the method includes the following steps S301-S309:

[0061] S301: The liquid level sensor detects the condensed water level in the refrigerant pipe water receiving tray;

[0062] S302: Is the temperature ≤ 65°C? If yes, proceed to step S306; otherwise, proceed to step S303;

[0063] S303: the water pump stops running, and the condenser fan operates in air cooling mode;

[0064] S304: Is the liquid level higher than the set liquid level? If yes, proceed to step S306; otherwise, proceed to step S305;

[0065] S305: The water pump stops running, and the condenser fan operates in air cooling mode;

[0066] S306: The water pump starts circulating operation, the system monitors the water temperature and liquid level in real time, and the condensing fan operates in a water cooling mode to achieve condensed water heating and evaporation;

[0067] S307: Check whether the condensation temperature is higher than 40°C. If yes, proceed to step S308; otherwise, proceed to step S309;

[0068] S308: The condensing fan starts the high-speed operation mode;

[0069] S309: The condensing fan is in low speed operation mode. When the condensing temperature is lower than 30°C, the condensing fan stops running.

[0070] The refrigerator in the present invention is composed of a refrigeration compartment, a water distributor, a condenser, an evaporator water tray, a liquid level sensor, a refrigerant pipe water tray, a circulating water pump, fin evaporation paper, an exhaust pipe and a control system thereof. The condensate treatment method is comprehensively controlled by the liquid level of the bottom water tray, and a condenser evaporation treatment system is formed by multiple means such as exhaust pipe heating, evaporation paper evaporation, and condenser evaporation, so as to ensure that no condensate overflows under complex and harsh working conditions.

In the present invention, a water receiving pan is provided under the refrigerator, which can increase the amount of condensate received without occupying additional volume and affecting the layout of the refrigerator. The exhaust pipe is extended to the bottom water receiving pan to heat the condensate.
