[0036] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a refrigerator, comprising:

[0037] The first warehouse S1;

[0038] The compressor 100 is arranged in the first storage body S1;

[0039] A fire monitoring device 200, wherein the fire monitoring device 200 is disposed in the first warehouse S1;

[0040] A water storage box 400 is disposed in the first storage body S1; and

[0041] The spray device 300 includes a pumping member 320 and a spray head 310. The pumping member 320 is configured to deliver water to the spray head 310. The spray head 310 is disposed toward the compressor 100. The pumping member 320 is configured to extract water from the water storage box 400.

[0042] The water pumping member 320 is activated in response to the fire information of the fire monitoring device 200 , so that the water in the water storage box 400 is sprayed toward the compressor 100 through the spray head 310 .

[0043] In the technical solution of the embodiment of the present application, a fire monitoring device 200 is provided in the first warehouse S1 where the compressor 100 is set, so as to collect environmental information in the first warehouse S1; a water storage box 400 is also provided in the first warehouse S1, and the pumping part 320 of the spraying device 300 is used to extract water in the water storage box 400; when the fire monitoring device 200 monitors the fire information, the pumping part 320 is used to extract water in the water storage box 400, so that the spray head 310 sprays water toward the compressor 100, so as to timely and effectively extinguish the fire source at the connection point and avoid the development of fire.

[0044] In some embodiments, the fire monitoring device 200 may be a smoke sensor, a carbon dioxide sensor, a temperature sensor and / or a camera. For example, the fire monitoring device 200 is a camera, which collects images or videos in the first warehouse S1. According to the images or videos, it is determined whether there is fire information in the first warehouse S1. For example, when the temperature sensor detects that the surface temperature in the first warehouse S1 is higher than the preset temperature threshold and the smoke sensor detects smoke, it is determined that there is fire information in the first warehouse S1. The pumping member 320 is activated in response to the fire information of the fire monitoring device 200, so that the water in the water storage box 400 is sprayed toward the compressor 100 through the nozzle 310.

[0045] In some embodiments, the nozzle 310 is configured as a rotating nozzle 310 and / or a movable nozzle 310. When it is determined that there is fire information in the first storage body S1, the source of the fire is determined based on the fire information, and the water spraying direction of the nozzle 310 or the position relative to the compressor 100 is controlled so that the nozzle 310 sprays water toward the source of the fire, so as to quickly and efficiently extinguish the fire and prevent the spread of the fire. For example, the camera collects images in the first storage body S1, and determines that the compressor 100 is on fire and the source of the fire based on the image. At this time, when the pumping part 320 is activated in response to the fire information of the fire monitoring device 200, based on the position of the fire source, the nozzle 310 is controlled to rotate and / or move, so that the water spraying direction and / or the position relative to the compressor 100 are consistent with the position of the fire source, and the water sprayed by the nozzle 310 is sprayed toward the fire source.

[0046] In this embodiment, the spray device 300 includes a driving assembly for driving the spray head 310 to rotate and / or move.

[0047] In some embodiments, the water pumping member 320 is a pump, such as a booster pump, which can be disposed in the water storage box 400. The pump is connected to the spray head 310 via a water pipe.

[0048] In some embodiments, the connection point where the compressor 100 is connected to the power supply of the refrigerator is prone to ignition and combustion, which is also an important reason for the compressor 100 to catch fire. Therefore, in order to promptly and effectively handle the fire of the compressor 100, the fire at the connection point needs to be handled in a timely manner. Therefore, the fire monitoring device 200 is at least arranged toward the connection point of the compressor 100, so that when the connection point catches fire, the fire information can be collected in time. The nozzle 310 is configured to be arranged at least toward the connection point of the compressor 100, so that the water sprayed by the nozzle 310 is sprayed toward the compressor 100.

[0049] As an optional implementation of the above embodiment, the refrigerator further includes a second warehouse body S2, an evaporator 500 and a water receiving tray 600; the first warehouse body S1 and the second warehouse body S2 are arranged separately from each other; the water receiving tray 600 and the evaporator 500 are arranged in the second warehouse body S2, and the water receiving tray 600 is arranged on the lower side of the evaporator 500; the water receiving tray 600 and the water storage box 400 are connected through a first valve 700. In the embodiment, the second warehouse body S2 is a refrigeration channel of the refrigerator, and the evaporator 500 performs heat exchange with the air in the second warehouse body S2 to cool the compartment of the refrigerator. During use, the surface of the evaporator 500 is frosted, so a defrosting operation is required. During the defrosting process, the defrosting water melted by the frost layer on the evaporator 500 is received by the water receiving tray 600.

[0050] The water receiving tray 600 and the water storage box 400 are connected via a first valve 700; when the first valve 700 is opened, the water in the water storage box 400 flows into the water receiving tray 600. Furthermore, the water in the water storage box 400 can be replenished by defrosting water, and the defrosting water can be consumed to prevent the defrosting water from overflowing and soaking the ground.

[0051] In some embodiments, the first compartment S1 and the second compartment S2 are separated from each other and share a wall surface, thereby saving space in the refrigerator. The water receiving tray 600 and the water storage box 400 are respectively located on opposite sides of the wall surface, and the first valve 700 can be opened on the wall surface; after the first valve 700 is opened, the water in the water receiving tray 600 flows into the water storage box 400. In this embodiment, the bottom surface of the water receiving tray 600 is higher than the bottom surface of the water storage box 400, so as to facilitate the flow of water in the water receiving tray 600.

[0052] In some embodiments, the first chamber S1 and the second chamber S2 are arranged through another space. A valve can be arranged in the space, and the two ends of the valve are connected to the water storage box 400 and the water receiving tray 600 through water pipes. After the first valve 700 is opened, the water in the water receiving tray 600 flows into the water storage box 400. In this embodiment, the bottom surface of the water receiving tray 600 is higher than the bottom surface of the water storage box 400, so as to facilitate the flow of water in the water receiving tray 600.

[0053] In some other embodiments, a water pump is further provided between the water storage box 400 and the water receiving tray 600 , and the water in the water receiving tray 600 is pumped into the water storage box 400 by the water pump.

[0054] As an optional implementation of the above embodiment, Figure 4 As shown, a liquid level sensor is provided inside the water storage box 400; and / or, a pressure sensor is provided on the outer side of the bottom of the water storage box 400; and / or, a gravity sensor is provided on the outer side of the bottom of the water storage box 400;

[0055] The first valve 700 is configured to open or close according to the liquid level signal of the liquid level sensor and / or the pressure signal of the pressure sensor and / or the gravity signal of the gravity sensor.

[0056] In the embodiment, a certain amount of water is required in the water storage box 400 to ensure that there is water to extinguish the fire when a fire occurs. To this end, in the embodiment, a liquid level sensor is provided in the water storage box 400; and / or a pressure sensor is provided on the outer side of the bottom of the water storage box 400; and / or a gravity sensor is provided on the outer side of the bottom of the water storage box 400.

[0057] When the liquid level corresponding to the liquid level signal collected by the liquid level sensor is lower than the preset liquid level value, it indicates that the water in the water storage box 400 is insufficient, and the main control board controls the first valve 700 to open so that the defrost water in the water receiving tray 600 can supplement the water in the water storage box 400.

[0058] When the pressure corresponding to the pressure signal collected by the pressure sensor is lower than the preset pressure value, it means that there is not enough water in the water storage box 400. The main control board controls the first valve 700 to open so that the defrost water in the water receiving tray 600 can replenish the water in the water storage box 400.

[0059] When the gravity corresponding to the gravity signal collected by the gravity sensor is lower than the preset gravity value, it means that the water in the water storage box 400 is insufficient, and the main control board controls the first valve 700 to open so that the defrost water in the water receiving tray 600 can supplement the water in the water storage box 400.

[0060] As an optional implementation of the above embodiment, the top of the water storage box 400 is at least partially open. In the embodiment, the fire extinguishing structure is set in the first compartment S1 mainly to improve the safety of the refrigerator; and the fire of the compressor 100 of the refrigerator is only an occasional event; the top of the water storage box 400 is at least partially open, and when the compressor 100 is not on fire, it can absorb the heat of the compressor 100 and reduce the temperature, which is conducive to reducing the probability of fire of the compressor 100.

[0061] In some other embodiments, the water storage box 400 is connected to the water receiving tray 600 through the first valve 700. The water in the water receiving tray 600 can flow into the water storage box 400 after the first valve 700 is opened. The water in the water receiving tray 600 comes from defrosting water. And the defrosting frequency of the refrigerator is much higher than the probability of fire of the compressor 100; after receiving the defrosting water, the water storage box 400 absorbs the heat of the compressor 100 and evaporates, so that the water in the water receiving tray 600 can be prevented from overflowing and causing the water to overflow onto the ground. For example, in some embodiments, when the water level in the water receiving tray 600 exceeds the preset water level, the first valve 700 can be controlled to open so that the water in the water receiving tray 600 flows into the water storage box 400. Since the top of the water storage box 400 is at least partially open, it absorbs the heat of the compressor 100 and evaporates, so that the water in the water receiving tray 600 can be prevented from overflowing and causing the water to overflow onto the ground.

[0062] In some embodiments, the water storage box 400 is disposed on one side of the compressor 100 in the horizontal direction. In an embodiment, the water receiving tray 600 is located at the lower side of the evaporator 500 and is substantially at the same horizontal position as the compressor 100; therefore, the water storage box 400 is disposed on one side of the compressor 100 in the horizontal direction, so that the positions of the water receiving tray 600 and the water storage box 400 are appropriate, so as to receive the defrost water in the water receiving tray 600. In some embodiments, the water storage box 400 is disposed on one side of the compressor 100 in the horizontal direction close to the second compartment S2.

[0063] As an optional implementation of the above embodiment, Figure 3 or Figure 4 As shown, the refrigerator also includes a main control board, which is signal-connected to the fire monitoring device 200 and the pumping component 320; the main control board is configured to receive the fire information and control the pumping component 320 to start or shut down based on the fire information.

[0064] In the embodiment, the fire monitoring device 200 monitors the environmental information in the first compartment S1; when the main control board determines that the environmental information is fire information, it controls the pumping component 320 to start, so that the water in the water storage box 400 is sprayed into the compressor 100 through the nozzle 310 to extinguish the fire, prevent the fire from spreading, and reduce user losses.

[0065] As an optional implementation of the above embodiment, the main control board is further configured to control the compressor 100 to be powered off based on the fire information. In the embodiment, when a fire occurs in the first compartment S1, the main control board controls the compressor 100 to be powered off to avoid a larger fire caused by a line fault in the refrigerator.

[0066] As an optional implementation of the above embodiment, Figure 3 As shown, the refrigerator also includes an alarm device; the main control board is connected to the alarm device by signal, and the main control board is used to output an alarm signal to the alarm device based on the fire information; the alarm device issues an alarm in response to the alarm signal. In an embodiment, when a fire occurs in the first warehouse S1, the main control board outputs an alarm signal to the alarm device; and the alarm device issues an alarm in response to the alarm signal, so that the user can deal with it in time to avoid more losses. For example, the alarm device can be a voice device; when a fire occurs in the first warehouse S1, the main control board controls the voice device to issue a prompt sound, such as a buzzer sound.

[0067] As an optional implementation of the above embodiment, the number of the nozzles 310 is at least two, and they are spaced around the compressor 100. In the embodiment, when it is determined that the compressor 100 is on fire, the nozzles 310 spaced around the compressor 100 start to spray water at different positions of the compressor 100 at the same time to hinder the development of the fire.

[0068] In some embodiments, a portion of the nozzles 310 are configured to be disposed toward the connection point of the compressor 100, and another portion of the nozzles 310 are configured to be disposed toward different sides of the compressor 100. A second valve is disposed between the pumping member 320 and each nozzle 310. The corresponding second valve is controlled to open according to the location of the fire. For example, when a fire occurs at the connection point, the second valve corresponding to the nozzle 310 disposed toward the connection point is controlled to open; and the second valve corresponding to the nozzle 310 disposed toward different sides of the compressor 100 is controlled to close; so that when the fire is extinguished at the fire point, there is enough water at the fire point for extinguishing the fire.

[0069] The embodiment of the present application also proposes a control method to control the refrigerator proposed in the above embodiment. The steps corresponding to the control method can be written into the main control board of the refrigerator. Specifically, the embodiment of the present application also proposes a control system for a refrigerator, including: one or more processors; a memory; and one or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the processor to implement the control method of the refrigerator as described above.

The main processor is a processor for processing data in the awake state, also known as a CPU (Central Processing Unit); the coprocessor is a low-power processor for processing data in the standby state. In some embodiments, the processor may be integrated with a GPU (Graphics Processing Unit), which is responsible for rendering and drawing the content to be displayed on the display screen. The processor may also include an AI (Artificial Intelligence) processor, which is used to process the control method operation of the control system of the refrigerator, so that the control method model of the control system of the refrigerator can be trained and learned autonomously to improve efficiency and accuracy.

[0072] The memory may include one or more computer-readable storage media, which may be non-transitory. The memory may also include a high-speed random access memory, and a non-volatile memory, such as one or more disk storage devices, flash memory storage devices. In some embodiments, the non-transitory computer-readable storage medium in the memory is used to store at least one instruction, which is used to be executed by the processor to implement the refrigerator control method of the refrigerator control system provided in the method embodiment of the present application.
