Description

Technical Field

[0002] A heat pump water heater is a device that uses heat pump technology to heat water; the working principle of a heat pump water heater is to absorb lower-temperature thermal energy from environmental heat sources (such as water, air) through components such as a compressor, evaporator, heat exchanger, insulated water tank and electronic automatic controller, and then convert it into higher-temperature thermal energy and release it into the circulating medium (such as water, air) as a high-temperature heat source output.

[0003] The heat pump water heater of the related technology includes a vertical water tank, which is connected to the vertical water tank with an inlet pipe and an outlet pipe. When the heat pump water heater heats the vertical water tank, the density of water changes with the temperature, and the density of cold water is greater than that of hot water. During heating, the hot water will flow toward the upper part of the vertical water tank, and the cold water will flow toward the lower part of the vertical water tank, causing the water temperature in the water tank to be stratified.

[0004] When the water temperature in the upper part of the vertical water tank reaches the temperature requirement, the water in the lower part of the vertical water tank is still at a low temperature or even cold water state. When the water tank is drained through the outlet pipe, only part of the water in the upper part of the water tank can meet the temperature requirement, thereby reducing the output of hot water from the vertical water tank.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0034] The heat pump water heater of the related technology includes a vertical water tank, which is connected to the vertical water tank with an inlet pipe and an outlet pipe. When the heat pump water heater heats the vertical water tank, the density of water changes with the temperature, and the density of cold water is greater than that of hot water. During heating, the hot water will flow toward the upper part of the vertical water tank, and the cold water will flow toward the lower part of the vertical water tank, causing the water temperature in the water tank to be stratified.

[0035] When the water temperature in the upper part of the vertical water tank reaches the temperature requirement, the water in the lower part of the vertical water tank is still at a low temperature or even cold water state. When the water tank is drained through the outlet pipe, only part of the water in the upper part of the water tank can meet the temperature requirement, thereby reducing the output of hot water from the vertical water tank.

[0036] In order to solve the above technical problems, the present application provides a heat pump water heater, in which a compressor can compress a refrigerant to form a high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters multiple air intake connecting pipes along the air intake connecting pipe at the same time, enters the air intake space of the first connecting pipe along the multiple air intake connecting pipes, enters the multiple air intake pipes along the air intake space, enters the multiple air intake pipes through the multiple air intake pipes and the second connecting pipe, and enters the multiple liquid outlet pipes. The high-temperature and high-pressure gas heats the water in the water storage chamber through the air intake pipe and the liquid outlet pipe, and the cooled gas is condensed into condensate along the liquid outlet pipe, and the condensate enters the liquid outlet space of the first connecting pipe through the multiple liquid outlet pipes, and enters the liquid outlet connecting pipe along the liquid outlet space, enters the liquid outlet connecting pipe through the multiple liquid outlet connecting pipes, and enters the evaporator and the compressor again for recycling; by dividing the water tank into multiple water storage chambers through multiple partitions, the phenomenon of water temperature stratification in a single water storage chamber is reduced, so that each water storage chamber has more hot water that meets the temperature requirements, thereby increasing the hot water output of the water tank and improving the heating efficiency of the cold water in the water storage chamber.

[0037] Combination Figures 1 to 3 A heat pump water heater includes a water tank 100 and a heating assembly 200. At least one partition 110 is arranged in the water tank 100 along the height direction of the water tank 100. Each partition 110 is used to divide the space in the water tank 100 into a plurality of independent water storage chambers 111. A water inlet pipe 120 and a water outlet pipe 130 are connected to the water tank 100 and located at the position where each water storage chamber 111 is located.

A heating assembly 200 is arranged on the water tank 100 and located at the position where each water storage chamber 111 is located. The heating assembly 200 is used to heat the water in the water storage chamber 111.

[0038] In the present embodiment, the water tank 100 is configured as a vertical water tank 100, and two partitions 110 are arranged inside the water tank 100 along the height direction of the water tank 100, and the two partitions 110 are used to divide the space inside the water tank 100 into three water storage chambers 111; the volumes of the three water storage chambers 111 can be set to be the same or different; the cross-section of the water tank 100 is set to be circular, and the partition 110 is arranged in conjunction with the circular water tank 100; the partition 110 is arranged inside the water tank 100 along the horizontal direction; in other embodiments, the partition 110 can be detachably connected inside the water tank 100, so as to facilitate the adjustment of the position of the partition 110, so as to adjust the volume size of each water storage chamber 111.

[0039] By adopting the above technical solution and the partition 110, the partition 110 can separate the space in the water tank 100 from top to bottom into a plurality of water storage chambers 111, thereby reducing the height of a single water storage chamber 111 and reducing the stratification of the water temperature in a single water storage chamber 111, so that a single water storage chamber 111 can have more hot water, and the hot water output of the plurality of water storage chambers 111 is increased; when the heating component 200 heats the water in the water storage chamber 111, the hot water flows toward the water storage chamber 111 because the density of the hot water is less than that of the cold water. The upper portion moves, and each water storage chamber 111 has more hot water that meets the temperature requirement. The hot water that meets the temperature requirement can be discharged through the water outlet pipe 130 of each water storage chamber 111, further increasing the hot water output of the multiple water storage chambers 111; by using multiple heating components 200 to heat the multiple water storage chambers 111 separately, the heating efficiency of the water in each water storage chamber 111 is improved, so that each water storage chamber 111 can have more hot water that meets the temperature requirement, thereby further increasing the hot water output of the water tank 100.

The water outlet pipe 130 is connected to the top of the water storage chamber 111, and the multiple water outlet pipes 130 are connected to each other. The water inlet pipe 120 and the water outlet pipe 130 are arranged on the same side of the water tank 100; the ends of the three water inlet pipes 120 away from the water tank 100 are provided with water inlet connecting pipes 121, and the water inlet connecting pipes 121 are arranged in the vertical direction, and the top of the water inlet connecting pipe 121 is connected to the uppermost The water inlet pipe 120 is connected to the water tank 100, and the bottom end of the water inlet connecting pipe 121 is used to connect with the water supply end of the municipal pipeline; the three water outlet pipes 130 are provided with water outlet connecting pipes 131 at the ends away from the water tank 100, and the water outlet connecting pipes 131 are arranged in the vertical direction. The bottom end of the water outlet connecting pipe 131 is connected with the lowest water outlet pipe 130, and the top end of the water outlet connecting pipe 131 is used to connect with the user's water use end. In other embodiments, the water inlet pipe 120 and the water outlet pipe 130 can also be arranged on different sides of the water tank 100.

[0042] By adopting the above technical scheme, since the density of hot water is less than that of cold water, when the water in the water storage chamber 111 is heated, the hot water is located at the top of the water storage chamber 111. By arranging the water outlet pipe 130 at the top of the water storage chamber 111, it is convenient to discharge the hot water at the top of the water storage chamber 111, thereby further increasing the hot water output of multiple water storage chambers 111; by arranging the water inlet pipe 120 at the bottom of the water storage chamber 111, the water inlet pipe 120 is arranged at a position far away from the water outlet pipe 130, thereby preventing the cold water entering the water inlet pipe 120 from disturbing the hot water on the upper part when the water is entering, thereby preventing the heat pump of the heat pump water heater from being frequently started and stopped; by interconnecting multiple water inlet pipes 120 through the water inlet connecting pipe 121, it is convenient to simultaneously transport cold water to multiple water storage chambers 111; by interconnecting multiple water outlet pipes 130 through the water outlet connecting pipe 131, it is convenient to simultaneously discharge the hot water in multiple water storage chambers 111.

[0043] Combination Figures 1 to 3 The heating component 200 includes multiple air inlet pipes 210 and multiple liquid outlet pipes 220. The multiple air inlet pipes 210 and the multiple liquid outlet pipes 220 are all wound around the outer wall of the water tank 100. The multiple air inlet pipes 210 are connected to the multiple liquid outlet pipes 220. The air inlet pipes 210 are configured to receive the high-temperature and high-pressure gas compressed by the compressor 900, and the liquid outlet pipes 220 are configured to discharge the condensate formed by the high-temperature and high-pressure gas exchanging heat with the water storage chamber 111.

[0044] In this embodiment, the heating assembly 200 includes three air inlet pipes 210 and three liquid outlet pipes 220; the air inlet pipes 210 and the liquid outlet pipes 220 are both arranged horizontally around the outer wall of the water tank 100; the three air inlet pipes 210 and the three liquid outlet pipes 220 are arranged in parallel and at intervals on the outer wall of each water storage chamber 111; the spacing between adjacent air inlet pipes 210 is the same as the spacing between adjacent liquid outlet pipes 220; the spacing between adjacent air inlet pipes 210 and liquid outlet pipes 220 is the same as the spacing between adjacent air inlet pipes 210.

[0045] By adopting the above technical solution, the compressor 900 can compress the refrigerant so that the refrigerant forms a high-temperature and high-pressure gas. At this time, the gas can enter into multiple air inlet pipes 210. The multiple air inlet pipes 210 are arranged around the outer wall of the water tank 100, so that the air inlet pipes 210 heated by the high-temperature and high-pressure gas can heat the water tank 100, thereby heating the water in the water storage chamber 111. The high-temperature and high-pressure gas in the air inlet pipe 210 is cooled after heat exchange and can be condensed to form condensate and discharged along the multiple liquid outlet pipes 220; the arrangement structure of the multiple air inlet pipes 210 and the multiple liquid outlet pipes 220 is simple, and the heating efficiency of the water in the multiple water storage chambers 111 is further improved; by adopting the arrangement of multiple air inlet pipes 210, the high-temperature and high-pressure gas compressed by the compressor 900 can enter the multiple air inlet pipes 210 at the same time, so that the high-temperature and high-pressure gas in the multiple air inlet pipes 210 simultaneously maintains a high temperature to heat the water in the water storage chamber 111, thereby further improving the heating efficiency of the water in the water storage chamber 111.

[0048] By adopting the above technical solution, by arranging multiple air inlet pipes 210 at the upper part of the water storage chamber 111, the high-temperature and high-pressure gas can first heat the water in the upper part of the water storage chamber 111, and then heat the water in the lower part of the water storage chamber 111, thereby preventing the water with a lower temperature at the bottom of the water storage chamber 111 from flowing toward the upper part of the water storage chamber 111, thereby further reducing the phenomenon of water temperature stratification in the water storage chamber 111; and by heating the water in the upper part of the water storage chamber 111, the water in the upper part of the water storage chamber 111 can reach the temperature requirement more quickly, thereby further improving the heating efficiency.

[0066] By adopting the above-mentioned technical scheme and the arrangement of the liquid outlet connecting pipe 600 and the liquid outlet connecting pipe 610, the condensate in the multiple liquid outlet spaces 312 of the multiple second connecting pipes 400 can enter the liquid outlet connecting pipe 610 along the multiple liquid outlet connecting pipes 600, thereby facilitating the simultaneous collection of the condensate in the multiple liquid outlet spaces 312 of the multiple second connecting pipes 400, so that the condensate is circulated again through the liquid outlet connecting pipe 610 into the condenser and compressor 900 of the heat pump water heater for recycling.

[0067] In this embodiment, the heat pump water heater also includes a throttling device 700, an evaporator 800 and a compressor 900. The condensed condensate can enter the throttling device 700. The throttling device 700 can adopt an electronic expansion valve, a thermal expansion valve or a capillary tube; the throttling device 700 can adjust the flow rate of the condensate; the evaporator 800 can receive the condensate, and the evaporator 800 exchanges heat with the surrounding environment such as air, absorbs heat in the environment, and makes the condensate evaporate into gas. At this time, the gas enters the compressor 900 and is further compressed by the compressor 900 to become a high-temperature and high-pressure gas; the high-temperature and high-pressure gas can enter along the air intake connecting pipe 510, thereby realizing the heating of the water in the multiple water storage chambers 111.

[0068] The embodiment of the present application provides a heat pump water heater, in which a compressor 900 can compress a refrigerant to form a high-temperature and high-pressure gas. The high-temperature and high-pressure gas enters into a plurality of intake connecting pipes 500 simultaneously along an intake connecting pipe 510, enters into an intake space 311 of a first connecting pipe 300 along the plurality of intake connecting pipes 500, enters into a plurality of intake pipes 210 along the intake space 311, enters into a plurality of liquid outlet pipes 220 through the plurality of intake pipes 210 and a second connecting pipe 400, and heats the water in a water storage chamber 111 through the intake pipe 210 and the liquid outlet pipe 220. The cooled gas condenses into condensate along the liquid outlet pipe 220, and the condensate enters into a liquid outlet space 312 of the first connecting pipe 300 through the plurality of liquid outlet pipes 220, enters into the liquid outlet connecting pipe 600 along the liquid outlet space 312, enters into the liquid outlet connecting pipe 610 through the plurality of liquid outlet connecting pipes 600, and enters into the evaporator 800 and the compressor 900 again for recycling.
