Description

Technical Field

[0001] The utility model relates to the field of water heaters, in particular to a double-evaporator air-energy high-temperature heat pump water heater. Background Art

[0002] Air-source heat pump water heater is also called air-source water heater. Its working principle is similar to that of air conditioner. It uses a small amount of electricity to drive the compressor. The high-pressure liquid working medium evaporates into gas in the evaporator after passing through the expansion valve and absorbs a large amount of heat energy from the air. The gaseous working medium is compressed by the compressor into high-temperature, high-pressure liquid, and then enters the condenser to release heat and heat the water. This cycle continues to heat the water.

[0003] When the air-source heat pump water heater is in use, the liquid refrigerant inside will absorb heat from the outside air through the evaporator and evaporate into gas. It will then be compressed by the compressor, condenser and other components, releasing the heat into the water to complete the heating of the water flow.

[0004] In order to facilitate the contact between the evaporator and the surrounding air and absorb the heat in the surrounding air, the air-source heat pump water heater generally uses a fan to accelerate the air flow around the evaporator. However, the space between the fan and the evaporator of the existing air-source heat pump water heater is small and is generally in a semi-closed state. The air around the evaporator that absorbs heat cannot be discharged in time, resulting in a decrease in the subsequent refrigerant heat absorption and evaporation rate, which is not conducive to the use of the air-source heat pump water heater. Summary of the Invention

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a double-evaporator air energy high-temperature heat pump water heater.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a dual-evaporator air-energy high-temperature heat pump water heater, including a protection mechanism, a heating mechanism installed inside the protection mechanism, the protection mechanism including an outer shell, the heating mechanism including a first evaporator and a second evaporator, the first evaporator and the second evaporator are both installed on the inner bottom of the outer shell, an angle is set between the first evaporator and the second evaporator, a second connecting pipe is installed between the first evaporator and the second evaporator, a water tank is fixedly connected to the inside of the outer shell, a condenser is fixedly connected to the inside of the water tank, a third connecting pipe is installed between the condenser and the second evaporator, a compressor is fixedly connected to the inside of the outer shell, a first connecting pipe is installed between the compressor and the first evaporator, and a fourth connecting pipe is installed between the compressor and the condenser.

[0007] As a further description of the above technical solution:

[0008] A panel is fixedly connected to the front of the shell, and the panel is located at the wide opening between the first evaporator and the second evaporator.

[0009] As a further description of the above technical solution:

[0010] A protective plate is fixedly connected to the interior of the panel, and there are multiple protective plates, which are arranged obliquely.

[0011] As a further description of the above technical solution:

[0012] A back plate is fixedly connected to the back of the shell, and the back plate is located at the narrow opening between the first evaporator and the second evaporator.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the back plate is fixedly connected with a connecting frame, and a fan is installed on the connecting frame.

[0015] As a further description of the above technical solution:

[0016] A plurality of protective strips are installed on the back of the back plate, and the positions of the protective strips correspond to the positions of the fans.

[0017] As a further description of the above technical solution:

[0018] A water inlet pipe is fixedly connected to the side wall of the water tank, and one end of the water inlet pipe away from the water tank extends to the outside of the shell.

[0019] As a further description of the above technical solution:

[0020] A water outlet pipe is fixedly connected to the side wall of the water tank. One end of the water outlet pipe away from the water tank extends to the outside of the shell. The water outlet pipe is located below the water inlet pipe.

[0021] The utility model has the following beneficial effects:

[0022] Compared with the prior art, this dual-evaporator air-energy high-temperature heat pump water heater, through the protection mechanism and the heating mechanism, is provided with an angle between the first evaporator and the second evaporator when in use. When the water heater is working, the first evaporator and the second evaporator will absorb the heat of the air inside the angle. Then the fan works to generate negative pressure in the shell, pulling the air inside the angle to be discharged from the narrow opening between the first evaporator and the second evaporator, and introducing the outside air into the shell from the wide opening between the first evaporator and the second evaporator, so that the water heater can timely discharge the low-temperature air between the first evaporator and the second evaporator when working, and attract the surrounding air to enter, which can effectively improve the heat absorption efficiency of the evaporator and facilitate the use of the water heater. Compared with conventional water heaters, which are generally semi-closed, the air around the evaporator that absorbs heat cannot be discharged in time, resulting in a decrease in the subsequent refrigerant heat absorption and evaporation rate, which is not conducive to the use of the air-energy heat pump water heater. The dual-evaporator air-energy high-temperature heat pump water heater has a better air duct structure. When in use, the refrigerant inside the evaporator can better absorb the heat in the surrounding air, which is convenient for use.

[0023] Compared with the existing technology, this dual-evaporator air-source high-temperature heat pump water heater passes through the first evaporator and the second evaporator. When in use, the liquid refrigerant will pass through the second evaporator and the first evaporator in turn, increasing the contact area between the evaporator and the air, so that the refrigerant can absorb heat from the surrounding air more quickly, making it easier for the water heater to heat the water flow more quickly.
