Description

Technical field:

[0001] The invention relates to a bottom heat dissipation and noise reduction system of an embedded refrigerator and a working method thereof, and belongs to the technical field of refrigerators. Background technology:

[0002] As people's requirements for decoration quality continue to increase, more home appliances require embedded installation, and there are more and more fully embedded refrigerators and free embedded refrigerators. For embedded refrigerators, how to ensure heat dissipation is an important issue that needs to be considered at the beginning of the design; because of the special installation method of embedded refrigerators, most of them adopt the bottom heat dissipation mode. At the same time, because the bottom environment of embedded refrigerators is relatively closed and the heat dissipation is poor, it is usually necessary to install a fan to make air convection and force heat dissipation; when the refrigerator is running, the cooling fan, refrigeration fan and compressor run at the same time, which will cause the overall noise value of the refrigerator to be too high, affecting the user experience.

[0003] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Summary of the invention:

[0004] The present invention aims to solve the problems existing in the above-mentioned prior art and provides a bottom heat dissipation and noise reduction system for an embedded refrigerator and a working method thereof, which can solve the noise problem caused by forced heat dissipation of the embedded refrigerator and the problem of heat dissipation difficulty of the embedded refrigerator.

[0005] The present invention adopts the following technical scheme: a bottom heat dissipation and noise reduction system of an embedded refrigerator, comprising a heat dissipation fan, a condenser, a condenser tray and a water receiving tray, the heat dissipation fan and the condenser tray are fixed together by screws, the condenser and the water receiving tray are placed on the condenser tray, the condenser comprises a condenser shell and a condenser pipeline located in the condenser shell, the embedded refrigerator comprises a refrigerator main control board, a refrigerator liner, a freezer liner, a compressor, a terminal and a refrigerator main wiring harness, the refrigerator main control board is installed on the top of the embedded refrigerator, the back of the refrigerator liner or the freezer liner of the embedded refrigerator is installed with an air duct, a refrigerator refrigeration fan is installed on the air duct, the refrigerator refrigeration fan is connected to one end of the refrigerator main wiring harness through a terminal, the other end of the refrigerator main wiring harness is connected to the refrigerator main control board through a terminal, the compressor and the heat dissipation fan are both connected to the refrigerator main wiring harness through a terminal, the other end of the refrigerator main wiring harness is connected to the refrigerator main control board through a terminal, the condenser shell is a closed structure, and liquid and solid heat exchange media are contained in the condenser shell.

[0006] Furthermore, refrigerator refrigerant is stored in the condenser pipeline.

[0007] Furthermore, a water pipe is connected to the water receiving tray, and the other end of the water pipe is connected to a water outlet hole arranged on the bottom plate of the refrigerator.

[0008] The present invention also adopts the following technical solution: a working method of a bottom heat dissipation and noise reduction system of an embedded refrigerator, the steps are as follows:

[0009] When the refrigerator is cooling normally, the refrigerator main control board controls the system program to make the refrigerator refrigeration fan work normally and deliver cold air to the refrigerated compartment or freezer compartment. At this time, when the refrigerator refrigerant passes through the bottom condenser, the temperature is much higher than the room temperature, and the condenser pipe temperature is also higher than the room temperature. At this time, the temperature of the heat exchange medium added inside the condenser shell is the room temperature. The medium inside the condenser plays a role of absorbing heat, reducing the temperature of the condenser pipe and the internal refrigerator refrigerant, and reducing the temperature of the entire system at the bottom of the refrigerator, playing the role of a heat dissipation fan;

[0010] When the refrigerator has finished refrigeration and the compressor stops working, the refrigerator main control board program controls the refrigeration fan to stop, and the compressor stops working. At this time, the temperature of the heat exchange medium inside the condenser has risen to the same temperature as the refrigerant, which is much higher than the room temperature. The refrigerator main control board program controls the cooling fan to start running, and lowers the temperature of the heat exchange medium inside the condenser by direct blowing;

[0011] When the temperature inside the refrigerator rises, it returns to the stage where the refrigeration fan and compressor are working but the heat dissipation fan is not working, and this cycle repeats.

[0012] The present invention has the following beneficial effects:

[0013] (1) The bottom heat dissipation and noise reduction system of the built-in refrigerator of the present invention can effectively reduce the noise generated by the built-in refrigerator when using the bottom fan to dissipate heat, and can also improve the bottom heat dissipation capacity of the built-in refrigerator.

[0014] (2) The present invention can effectively avoid the simultaneous operation of the refrigeration fan and the heat dissipation fan, reduce the noise caused by fan resonance, and better meet the requirements of high-end refrigerators. At the same time, it can also greatly reduce the heat of the system and use the excess heat to evaporate the defrost water generated by the refrigerator. Description of the drawings:

[0015] Figure 1 It is a schematic diagram of the heat dissipation and noise reduction system at the bottom of the built-in refrigerator of the present invention. Specific implementation method:

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] The bottom heat dissipation and noise reduction system of the built-in refrigerator of the present invention comprises a heat dissipation fan 1, a condenser 2, a condenser tray 3 and a water receiving tray 4. The heat dissipation fan 1 and the condenser tray 3 are fixed together by screws, and the condenser 2 and the water receiving tray 4 are placed on the condenser tray 3.

[0018] The condenser 2 includes a condenser shell and a condenser pipe located in the condenser shell, and the refrigerator refrigerant is stored in the condenser pipe. The condenser shell is a closed structure that can meet the requirements of containing liquid, solid and other heat exchange media without leakage. When using, a certain amount of water (or other media with faster heat exchange, liquid, solid or gas) needs to be added to the condenser shell in advance.

[0019] A water pipe 40 is connected to the water receiving tray 4, and the other end of the water pipe 40 is connected to a water outlet hole (not shown) arranged on the bottom plate of the refrigerator.

[0020] The top of the built-in refrigerator of the present invention is equipped with a refrigerator main control board, the back of the refrigerator or freezer of the built-in refrigerator is equipped with an air duct, a refrigerator refrigeration fan is installed on the air duct by screws, the refrigerator refrigeration fan is connected to one end of the refrigerator main wiring harness through a terminal, and the other end of the refrigerator main wiring harness is connected to the refrigerator main control board through a terminal, so that the refrigerator main control board controls the refrigerator refrigeration fan. The built-in refrigerator of the present invention also includes a compressor, the compressor and the heat dissipation fan are both connected to the refrigerator main wiring harness through a terminal, and the other end of the refrigerator main wiring harness is connected to the refrigerator main control board through a terminal, so that the refrigerator main control board controls the compressor and the heat dissipation fan.

[0021] The working principle of the bottom heat dissipation and noise reduction system of the built-in refrigerator of the present invention is as follows:

[0022] When the refrigerator is refrigerating normally, the refrigerator main control board controls the system program to make the refrigerator refrigeration fan work normally and deliver cold air to the inside of the refrigerated compartment or the freezer compartment; at this time, when the refrigerator refrigerant passes through the bottom condenser, the temperature is far higher than the room temperature, and the temperature of the condenser pipe will also be higher than the room temperature. At this time, the temperature of the heat exchange medium added inside the condenser shell is the room temperature. At this time, the medium inside the condenser plays a role of absorbing heat, greatly reducing the temperature of the condenser pipe and the internal refrigerator refrigerant, effectively reducing the temperature of the entire system at the bottom of the refrigerator, and playing the role of a heat dissipation fan. In the refrigeration link of the entire refrigerator, the heat dissipation fan at the bottom does not work, and the working parts are the refrigeration fan and the compressor. A noise source is reduced in the system, which will effectively improve the noise.

[0023] When the refrigerator completes refrigeration and the compressor stops working, the refrigerator main control board program controls the refrigeration fan to stop and the compressor stops working. At this time, the temperature of the heat exchange medium inside the condenser has risen to the same temperature as the refrigerant, which is much higher than the room temperature. The refrigerator main control board program controls the heat dissipation fan to start running, and lowers the temperature of the heat exchange medium inside the condenser by direct blowing. At this stage, only the heat dissipation fan works, the refrigerator refrigeration fan and compressor do not work, and only one fan is running in the entire system. The refrigerator noise will also be improved.

[0024] When the temperature inside the refrigerator rises, the refrigeration fan and compressor return to the stage where they are working but the heat dissipation fan is not working. This cycle can effectively reduce the noise of the entire system and speed up the heat exchange efficiency between the bottom of the refrigerator and the external space.

[0025] The bottom heat dissipation and noise reduction system of the built-in refrigerator of the present invention has a heat dissipation fan at the bottom connected to the condenser tray at the bottom, and reduces the heat of the bottom system by accelerating the air flow. The bottom condenser is placed on the condenser tray, and the refrigerator main control board program controls the separate operation of the refrigeration fan and the heat dissipation fan. When the refrigerator is refrigerating, the refrigeration fan runs, and the coolant inside the condenser shell absorbs the excess heat at the bottom. When the refrigerator is defrosting or the compressor is stopped, the bottom heat dissipation fan works to take away the excess heat of the bottom of the refrigerator and the coolant, so as to avoid the two fans operating at the same time, thereby avoiding the generation of audio resonance and causing the excessive noise of the entire refrigerator.

[0026] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
