Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a compressor refrigeration host. Background Art

[0002] A water-heated mattress, also known as a temperature-controlled water-heated mattress, consists of a water-heated mattress and a water tank. The working principle is to heat the water through the water tank and transport it to the water-heated mattress through a submersible pump to warm the human body. The water-heated mattress uses water as the medium during the heating process and does not generate any electromagnetic radiation. Electric blankets are heated by electric heating wires, and the electromagnetic radiation generated is far beyond the human body's tolerance.

[0003] However, the existing water-heated mattress adopts semiconductor refrigeration. In order to ensure the compact appearance of the main unit, only low-power semiconductors can be used, and the refrigeration efficiency is low. If high-power semiconductors are used, the heat generated requires larger fans and heat sinks, which will greatly increase the space burden of the main unit and increase the working noise of the main unit, thereby affecting the user's experience of using the water-heated mattress. In addition, the water-heated mattress controls the temperature of the water-heated mattress by adding liquid, but impurities in the liquid will flow with the liquid. At this time, when the liquid flows into the water pipe, the impurities in the liquid are easy to adhere to the inner wall of the water pipe and produce scale. As the amount of scale continues to increase, it will not only affect the refrigeration effect, but also cause the water pipe to be blocked by impurities. Utility Model Content

[0027] Working principle: When in use, first, when adding liquid to the inside of the water tank 1, the liquid flows from the water adding pipe 21 to the inside of the filter tube 6. At this time, the liquid passes through the primary sieve plate 7 to filter out the impurities at the first level, and the larger impurities are filtered out. When the liquid after the first level of impurity removal reaches the secondary sieve plate 8, since the mesh diameter of the secondary sieve plate 8 is smaller than the mesh diameter of the primary sieve plate 7, the secondary sieve plate 8 can perform secondary impurity removal on the liquid after the first level of impurity removal.

The water tank 1, the plate heat exchanger 2, the compressor 3, the heat sink 4, and the fan 5 cooperate to form a refrigeration host. A PTC heater is installed at the water outlet of the refrigerant. When heating is required, the compressor 3 does not work, and the PTC heater works to realize the heating function of the refrigeration host. When cooling is required, the PTC heater does not work, and the compressor 3 works to realize the cooling function. Finally, the water pump at the water tank 1 is turned on. The water in the water tank 1 flows to the water outlet pipe 11. The water at the water outlet pipe 11 flows to the inside of the plate heat exchanger 2 through the connecting pipe 15. The water in the plate heat exchanger 2 can be transported to the water inlet of the water-heating mattress at the drainage end 16. The water at the water outlet of the water-heating mattress flows to the inside of the return pipe 10 and then enters the inside of the water tank 1 through the water inlet end 9.
