[0030] Embodiment 1

[0031] The prior art mainly adopts the way of manually pouring out the water in the water pan or evaporating the condensed water by using the heat of the refrigeration system. However, the manual way is more troublesome as it needs to be poured out regularly. The scheme of evaporating the condensed water by using the heat of the refrigeration system cannot meet the needs of large refrigerators or in high temperature and high humidity environment, resulting in overflow of the condensed water.

[0032] In view of the above problems, the present application provides a refrigerator in the preferred embodiment 1, specifically, Figure 1 An optional structural schematic diagram of the refrigerator is shown in FIG. 1, which shows that the refrigerator comprises: Figure 1

[0033] A refrigeration compartment 1, the cabinet of the refrigerator defines the refrigeration compartment 1, the refrigeration compartment 1 is provided with shelves 6 and is installed with a cabinet door 13;

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

[0035] As shown in FIG. 1, the evaporator is located above the inside of the refrigeration compartment 1, which is used to provide cold energy for the refrigeration compartment 1 to achieve the effect of cold storage; Figure 1

[0036] An evaporator water pan 5 located below the evaporator, which is used to receive the condensed water generated by the evaporator;

[0037] A refrigerant pipe water pan 8 located below the refrigeration compartment 1, the refrigerant pipe water pan 8 is connected with the evaporator water pan 5, which is used to receive the condensed water discharged from the evaporator water pan 5, wherein the exhaust pipe 12 of the compressor 14 passes through the refrigerant pipe water pan 8 to heat the condensed water in the refrigerant pipe water pan 8.

[0038] ​​In the above-mentioned embodiments, a condensate evaporation system for a refrigerator is provided, which includes two condensate water pans, one being an evaporator water pan located below the evaporator for receiving the condensate water generated by the evaporator, and the other being a refrigerant pipe water pan located below the refrigeration compartment, which is connected with the evaporator water pan for receiving the condensate water discharged from the evaporator water pan, wherein the exhaust pipe of the compressor passes through the refrigerant pipe water pan to heat the condensate water in the refrigerant pipe water pan. In the prior art, the condensate water is usually collected by the condensate water pan, and the condensate water cannot be quickly and effectively treated after the condensate water pan is full. In the present application, the bottom water pan is arranged below the refrigerator, which can increase the capacity of the condensate water without occupying additional space and affecting the layout of the refrigerator. The exhaust pipe is extended to the bottom water pan to heat the condensate water. When the condensate water is excessive, the system starts to heat the bottom water pan by the exhaust pipe to increase the temperature of the condensate water in the bottom water pan and accelerate the evaporation of the condensate water, effectively solving the problem of condensate water accumulation or overflow and improving the condensate water treatment capacity of the refrigerator and the operation stability of the refrigerator in various environments, especially in high-temperature and high-humidity environments.

[0039] In a preferred embodiment of the present application, an evaporation paper is further arranged in the refrigerant pipe water pan 8 for increasing the evaporation area of the condensate water. The evaporation paper is preferably a fin-type evaporation paper. The evaporation paper can increase the evaporation area of the condensate water, and the fin-type evaporation paper is preferably used to further increase the evaporation area. The bottom water pan is arranged with the compressor exhaust pipe 12 and the evaporation water absorbing paper to increase the temperature of the bottom condensate water and its evaporation surface area, and double measures are taken to increase the evaporation rate of the condensate water and further remove the condensate water.

[0040] Preferably, the refrigerator further includes a drain pipe, the water inlet end of the drain pipe being connected with the refrigerant pipe water pan 8, and the water outlet end of the drain pipe being connected with the condenser 3 for passing the condensate water in the refrigerant pipe water pan 8 to the condenser 3; and a circulating water pump 10 arranged on the drain pipe for conveying the condensate water in the drain pipe. As shown in Figure 1 When the evaporation of the condensate water cannot be achieved by only heating by the exhaust pipe 12 and the evaporation paper, the third measure can be taken, i.e., the condensate water is sprayed on the surface of the condenser 3, and the condensate water is heated and evaporated by the fins and copper pipes of the condenser 3. Figure 1 As shown in , the condenser 3 is located at the upper part of the refrigerator, and the refrigerant pipe water pan 8 is located at the lower part of the refrigerator, so the circulating water pump 10 is used to convey the condensate water in the refrigerant pipe water pan 8 to the condenser 3. Especially in the case that the amount of the condensate water generated by the heating by the exhaust pipe 12 and the evaporation by the evaporation paper is greater than the amount of the condensate water evaporated, the circulating water pump 10 is started to establish water circulation and spray on the surface of the condenser 3, and the condensate water is heated and evaporated by the waste heat of the condenser 3. The multiple measures are taken to form a condensate water evaporation treatment system to ensure that there is no condensate water overflow 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 freezer also includes a water distributor 2 located above the condenser 3. The outlet end of the drain pipe is connected to the water distributor 2, which is used to spray the condensate in the drain pipe onto the condenser 3. By spraying, the contact area between the condensate and the condenser 3 is increased, further improving the evaporation rate of the condensate and preventing the accumulation of condensate.

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

[0043] To achieve precise control over condensate evaporation, the refrigerator of this invention further includes: a liquid level sensor 7, located within the refrigerant pipe water tray 8, for detecting the water level in the refrigerant pipe water tray 8; and a water temperature sensor 9, located within the refrigerant pipe water tray 8, for detecting the water temperature in the refrigerant pipe water tray 8. By controlling condensate evaporation through water level and water temperature signals, the amount of condensate evaporation can be precisely controlled, allowing for corresponding evaporation control for different amounts of condensate, thus achieving optimal evaporation performance.

[0044] The present invention uses a top-mounted compressor 14, such as Figure 1 As shown, the compressor 14 is located above the refrigeration compartment 1. Therefore, 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 tray 8 to heat the condensate in the refrigerant pipe water tray 8. This invention leads the exhaust pipe 12 to the lower water tray, allowing it to pass under or inside the refrigerant pipe water tray 8 to heat the condensate in the refrigerant pipe water tray 8.

[0045] like Figure 1 As shown, this invention places the refrigerant pipe drip tray 8 at the bottom of the freezer, avoiding the impact of placing it at the top on the refrigeration system layout or at the back on the freezer's width. Placing the drip tray 8 at the bottom does not affect the overall layout of the refrigeration system and the freezer. Furthermore, a larger drip tray 8 can be installed at the bottom to increase the water capacity, effectively solving the problem of condensate accumulation or overflow in commercial freezers that need to handle large amounts of condensate. The larger drip tray 8 also allows for the installation of a larger evaporation paper, further improving the evaporation rate and enhancing the freezer's condensate handling capacity.

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

[0047] In a common low-temperature and low-humidity environment, the exhaust pipe 12 heats the water in the refrigerant pipe water receiving tray 8, and the heated water is absorbed by the multi-layer evaporative paper, so as to realize condensate water heating and evaporation. At this time, since the refrigeration system generates less condensate water, the liquid level detected by the liquid level sensor 7 will not be exceeded, and the condenser fan operates according to the refrigeration demand control logic.

[0048] In a high-temperature and high-humidity environment, if the door is frequently opened and closed, a large amount of condensate water will be generated after the hot air entering through the cabinet door 13 contacts the evaporator. The single heating and evaporative paper evaporation of the exhaust pipe 12 will result in a situation that the generated condensate water 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 to decrease. At this time, after the control system receives the high water level signal and the low water temperature signal, the circulating water pump 10 is started to discharge the condensate water into the water distributor 2, which uniformly sprays the condenser 3. The fins and copper pipes of the condenser 3 heat the condensate water and evaporate a part of the condensate water, until the liquid level and water temperature in the water receiving tray decrease.

[0049] Embodiment 2

[0050] In the preferred embodiment 2 of the present application, a refrigerator control method is provided, which is applied to the refrigerator in the above-mentioned embodiment 1. Specifically, Figure 2 An optional flowchart of the method is shown as Figure 2 The method comprises the following steps S202-S206:

[0051] S202: detecting the liquid level in the refrigerant pipe water receiving tray and the water temperature in the refrigerant pipe water receiving tray;

[0052] S204: judging whether the liquid level in the refrigerant pipe water receiving tray and the water temperature in the refrigerant pipe water receiving tray meet the preset evaporation condition;

[0053] S206: controlling the operation of the refrigerator according to the judgment result.

[0054] In the above-mentioned embodiments, a condensate water evaporation system for a refrigerator is provided, which includes two condensate water pans, one being an evaporator water pan located below the evaporator for receiving the condensate water generated by the evaporator, and the other being a refrigerant pipe water pan located below the refrigerating compartment, the refrigerant pipe water pan being connected with the evaporator water pan for receiving the condensate water discharged from the evaporator water pan, wherein the exhaust pipe of the compressor passes through the refrigerant pipe water pan to heat the condensate water in the refrigerant pipe water pan. In the prior art, the condensate water is usually received by the condensate water pan, but the condensate water cannot be quickly and effectively treated after the condensate water pan is full. In the present application, the bottom water pan is arranged below the refrigerator, which can increase the receiving capacity of the condensate water without occupying additional space and affecting the layout of the refrigerator. Moreover, the exhaust pipe is extended to the bottom water pan to heat the condensate water. When the condensate water is excessive, the system starts to heat the bottom water pan by the exhaust pipe to increase the temperature of the condensate water in the bottom water pan and accelerate the evaporation of the condensate water, thereby effectively solving the problems of condensate water accumulation or overflow and improving the condensate water treatment capacity of the refrigerator and the operation stability of the refrigerator in various environments, especially in high-temperature and high-humidity environments.

[0055] In a preferred embodiment of the present application, as shown in Figure 1 The liquid level sensor 7 is arranged in the refrigerant pipe water pan 8 for detecting the water level in the refrigerant pipe water pan 8, and the water temperature sensor 9 is arranged in the refrigerant pipe water pan 8 for detecting the water temperature in the refrigerant pipe water pan 8. The water level in the refrigerant pipe water pan and the water temperature in the refrigerant pipe water pan are determined to determine whether the preset evaporation condition is met, including: determining whether the water level in the refrigerant pipe water pan is greater than or equal to the preset water level and / or the water temperature in the refrigerant pipe water pan is less than or equal to the preset water temperature; when the water level in the refrigerant pipe water pan is greater than or equal to the preset water level and / or the water temperature in the refrigerant pipe water pan is less than or equal to the preset water temperature, it is determined that the preset evaporation condition is met, otherwise, it is determined that the preset evaporation condition is not met. The water level in the refrigerant pipe water pan and the water temperature in the refrigerant pipe water pan can reflect the amount of condensate water, and the water level rises or the water temperature decreases when the condensate water increases. Therefore, the water level in the refrigerant pipe water pan and the water temperature in the refrigerant pipe water pan are determined to determine the subsequent condensate water control scheme.

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

[0057] In the common low-temperature and low-humidity environment, i.e. the preset evaporation condition is not met, the exhaust pipe heats the condensate water in the water pan of the refrigerant pipe, and the heated water is absorbed by the multi-layer evaporation paper to realize the evaporation of the heated condensate water. At this time, the refrigeration system produces less condensate water, which will not exceed the liquid level detected by the liquid level sensor, and the condenser fan operates according to the refrigeration demand control logic.

[0058] In the high-temperature and high-humidity environment, if the door is frequently opened and closed, a large amount of condensate water will be generated after the hot air entering through the door contacts the evaporator. The single evaporation mode of the exhaust pipe heating and the evaporation paper will cause the generated condensate water to be greater than the evaporation amount, which will cause the liquid level in the water pan of the refrigerant pipe to rise to the detection position of the liquid level sensor, and the water temperature to decrease. At this time, after the control system receives the high water level signal and the low water temperature signal, the circulating water pump is started to discharge the condensate water into the water distributor, which uniformly sprays the condenser, the fins and the copper pipe of the condenser heat the condensate water and evaporate part of the condensate water, until the liquid level and the water temperature in the water pan decrease.

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

[0060] In the preferred embodiment 2 of the present application, another refrigerator control method is further provided, specifically, Figure 3 An optional flow chart of the method is shown in FIG. 3, and the method comprises the following steps S301-S309: Figure 3

[0061] S301: The liquid level sensor detects the liquid level of the condensate water in the water pan of the refrigerant pipe;

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

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

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

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

[0066] S306: The water pump is started to run in a circulating mode, the system monitors the water temperature and its liquid level in real time, and the condensing fan operates in a water cooling mode to realize the condensing water temperature rise and its evaporation;

[0067] S307: Whether the condensing temperature is higher than 40℃? If yes, go to step S308, otherwise, go to step S309;

[0068] S308: The condensing fan is started to run in a high speed mode;

[0069] S309: The condensing fan is started to run in a low speed mode, and when the condensing temperature is lower than 30℃, the condensing fan is stopped to run.

[0070] In the application, the refrigerator is composed of a refrigeration chamber, a water distributor, a condenser, an evaporator water tray, a liquid level sensor, a refrigerant pipe water tray, a circulating water pump, a fin evaporative paper, an exhaust pipe and a control system thereof. The condensing water treatment mode is comprehensively controlled through the bottom water tray liquid level, and a condenser evaporation treatment system is formed by multiple means such as the exhaust pipe heating, the evaporative paper evaporation and the condenser evaporation, so as to ensure that there is no condensing water overflow under complex and poor working conditions.

[0073] In the above embodiment, a condensing water evaporation system for a refrigerator is provided, which includes two condensing water water trays, one of which is an evaporator water tray located below the evaporator for receiving the condensing water generated by the evaporator, and the other is a refrigerant pipe water tray located below the refrigeration chamber, which is connected with the evaporator water tray for receiving the condensing water discharged from the evaporator water tray. The exhaust pipe of the compressor passes through the refrigerant pipe water tray to heat the condensing water in the refrigerant pipe water tray. In the prior art, the condensing water water tray is usually used to receive the condensing water, but it cannot be quickly and effectively treated when the water tray is full of condensing water. In the application, the water tray is arranged below the refrigerator, which can increase the receiving capacity of the condensing water without occupying additional volume and affecting the layout of the refrigerator. The exhaust pipe is extended to the bottom water tray to heat the condensing water. When the condensing water is too much, the system starts the exhaust pipe to heat the bottom water tray, increases the temperature of the condensing water in the bottom water tray, and accelerates the evaporation of the condensing water, effectively solving the problem of condensing water accumulation or overflow, and improving the condensing water treatment capacity of the refrigerator and the running stability of the refrigerator in various environments, especially in high temperature and high humidity environments.
