[0038] like Figure 1 to Figure 2 As shown, the utility model provides a temperature regulating pad cold and warm water circulation machine, comprising: a refrigeration compressor 1, an electric heater, a water storage tank 2, and a temperature regulating pad;

[0039] The evaporator 11 of the refrigeration compressor 1 is installed in the water storage tank 2, the condenser 12 of the refrigeration compressor 1 is placed outside the water storage tank 2 and is connected to a cooling fan group 13, and both ends of the evaporator 11 are connected to the refrigeration compressor 1 and the condenser 12 respectively through a refrigeration connecting pipe group 41;

[0040] The liquid working medium in the water tank 2 of the heating and cooling water circulation machine of the temperature regulating pad is provided with cooling energy by the refrigeration compressor 1. The evaporator 11 of the refrigeration compressor 1 is installed at the inner bottom of the water tank 2. The liquid working medium in the water tank 2 is cooled by the evaporator 11 of the refrigeration compressor 1. The condenser 11 of the refrigeration compressor 1 is externally placed and heat is dissipated by the cooling fan group 13, thereby realizing the cooling function of the temperature regulating pad.

[0041] The electric heater is installed in the water tank 2 to realize the heating function of the temperature regulating pad. A drainage pump 21 and a return pump 22 are also installed in the water tank 2. The drainage pump 21 and the return pump 22 are connected to the water inlet end and the water outlet end of the temperature regulating pad through a circulation connecting pipe group 42, thereby realizing the circulation of liquid working medium between the water tank 2 and the temperature regulating pad, so that the temperature rises rapidly and evenly.

[0042] Specifically, a temperature probe 6 is also installed in the water storage tank 2, and the temperature probe 6 is electrically connected to the drainage pump 21, the return pump 22, the refrigeration compressor 1, the electric heater, and the PLC controller 5;

[0043] During refrigeration, the refrigeration compressor 1, the drainage pump 21, the return pump 22, and the cooling fan 133 are started, and the refrigerant in the refrigeration compressor 1 circulates back to the refrigeration compressor 1 after passing through the condenser 12 and the evaporator 11, and continuously cools the liquid working medium in the water tank 2. At the same time, the drainage pump 21 and the return pump 22 are started synchronously, and the liquid working medium in the water tank 2 circulates in the water tank 2 and the temperature regulating pad through the drainage pump 21 and the return pump 22, and evenly transfers the cold energy until the temperature probe 6 detects that the liquid working medium in the water tank 2 reaches the temperature threshold, and stops;

[0044] During heating, the electric heater starts to heat the liquid working medium in the water tank 2, and the drainage pump 21 and the return pump 22 are started synchronously. The liquid working medium in the water tank 2 circulates in the water tank 2 and the temperature regulating pad through the action of the drainage pump 21 and the return pump 22, and transfers heat energy evenly until the temperature probe 6 detects that the liquid working medium in the water tank 2 reaches the temperature threshold and stops.

[0045] like Figures 1 to 3 As shown, specifically, the heat dissipation fan group 13 includes heat dissipation fins 131, a heat conduction pipe 132 of a continuous S-shaped structure, and a heat dissipation fan 133; a plurality of the heat conduction pipes 132 are vertically fixedly installed in a support frame 134 and arranged horizontally, the heat conduction pipe 132 is a hollow structure, and its liquid outlet end is connected to the liquid inlet end of the refrigeration compressor 1, so as to form a cooling medium circulation in the refrigeration compressor 1, the support frame 134 is a square structure, and the heat conduction pipe 132 passes through the heat dissipation fins 131 in the horizontal direction and extends along the height direction of the heat dissipation fins 131, so as to increase the contact area with the air through the heat dissipation fins 131 and quickly dissipate heat.

[0046] The cooling fan 133 is installed on the rear side of the support frame 134 , and a cooling air duct is formed between adjacent heat pipes 132 . When the cooling fan 133 is started, air is accelerated through the cooling air duct, and heat is dissipated by increasing the air flow rate.

[0047] like Figures 4 to 5As shown, specifically, the refrigeration compressor 1, the electric heater, and the water storage tank 2 are all installed on the support platform 7, and the outer cover shell 8 is snap-connected with the support platform 7, so that the temperature regulating pad cold and warm water circulation machine is portable.

[0048] Specifically, the top of the water tank 2 is configured with an injection pipe 23, and the outer cover shell 8 around the injection pipe 23 is configured with a sunken recessed platform 51. The injection pipe 23 is threadedly connected to a tank cover 24, and the combined height of the tank cover 24 and the injection pipe 23 is lower than the depth of the recessed platform 51. The design of the recessed platform 51 provides protection for the injection pipe 23 to prevent the injection pipe 23 from being damaged by external force collision.

[0049] Specifically, the PLC controller 5 is fixed on the outer cover shell 8 .

[0050] A method for controlling a temperature regulating pad cold and warm water circulation machine comprises the following steps;

[0051] S1: Select cooling or heating mode and set the temperature threshold;

[0052] S2: When the cooling mode is selected, the cooling compressor 1, the drainage pump 21, the return pump 22, and the cooling fan 133 are started until the temperature controller probe detects that the liquid working medium in the water storage tank 2 reaches the temperature threshold and stops;

[0053] When the heating mode is selected, the drainage pump 21, the return pump 22, and the electric heater are started until the temperature controller probe detects the liquid working medium in the water storage tank 2 and stops when the temperature threshold is reached.

[0054] Furthermore, the refrigeration mode also includes a refrigeration maintenance mode. When the thermostat probe detects that the liquid working medium in the water tank 2 has reached the refrigeration temperature threshold, the temperature increases to above the refrigeration maintenance temperature threshold, and the refrigeration compressor 1, the drainage pump 21, the return pump 22, and the cooling fan 133 are started again.

[0055] Furthermore, the heating mode also includes a heating maintenance mode. When the thermostat probe detects that the liquid working medium in the water tank 2 reaches the heating temperature threshold, the temperature drops below the heating maintenance temperature threshold, and the drainage pump 21, the return pump 22, and the electric heater are started again.

[0056] Specifically, the temperature control range in the present application is within the range of 20 degrees to 30 degrees above zero.

[0057] The working principle and working process of the utility model are as follows:

[0058] During refrigeration, the refrigeration compressor 1, the drainage pump 21, the return pump 22, and the cooling fan 133 are started, and the refrigerant in the refrigeration compressor 1 circulates back to the refrigeration compressor 1 after passing through the condenser 12 and the evaporator 11, and continuously cools the liquid working medium in the water tank 2. At the same time, the drainage pump 21 and the return pump 22 are started synchronously, and the liquid working medium in the water tank 2 circulates in the water tank 2 and the temperature regulating pad through the drainage pump 21 and the return pump 22, and evenly transfers the cold energy until the temperature probe 6 detects that the liquid working medium in the water tank 2 reaches the temperature threshold, and stops;

[0059] During heating, the electric heater starts to heat the liquid working medium in the water tank 2, and the drainage pump 21 and the return pump 22 are started synchronously. The liquid working medium in the water tank 2 circulates in the water tank 2 and the temperature regulating pad through the action of the drainage pump 21 and the return pump 22, and transfers heat energy evenly until the temperature probe 6 detects that the liquid working medium in the water tank 2 reaches the temperature threshold and stops.

[0060] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the utility model should still fall within the scope of this patent.
