Description

Technical Field

[0001] This utility model belongs to the technical field of air source heat pump units, and particularly relates to a water tank device for an integrated air source heat pump unit. Background Technology

[0002] Air source heat pump units, also known as air-source heat pump units, rely on refrigerant (R134a, R417A, etc.) to absorb low-temperature heat energy from the air, which is then compressed by the compressor and converted into high-temperature heat energy to heat the water. An air source heat pump unit includes components such as a compressor, condenser, capillary tube, evaporator, and sealed piping. The piping is filled with refrigerant, providing both heating and cooling functions. The compressor compresses the returning low-pressure refrigerant, turning it into a high-temperature, high-pressure gas, which is then discharged. This high-temperature, high-pressure refrigerant gas flows through copper pipes wrapped around the outside of the water tank, where heat is conducted to the tank. The cooled refrigerant, under continuous pressure, liquefies and enters the evaporator through the expansion valve or capillary tube. Due to the sudden pressure drop in the evaporator, the liquid refrigerant rapidly evaporates into a gaseous state, absorbing a large amount of heat. Meanwhile, under the action of the fan, a large amount of air flows over the outer surface of the evaporator. The energy in the air is absorbed by the evaporator, the moisture in the air is condensed and discharged, and the air temperature is reduced. Then, the refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle.

[0003] In existing technologies, after long-term use, the inner wall of the water tank of an air source heat pump unit is prone to the accumulation of scale and other pollutants, which can easily contaminate the water quality. In order to reduce pollution, the inside of the water tank needs to be cleaned regularly. However, since the water tank usually does not have a self-cleaning function, users need to use tools to clean it manually, which is complicated and laborious, and cleaning and maintenance are inconvenient. Utility Model Content

[0004] To address the technical problem that existing air source heat pump units' water tanks lack self-cleaning functions, resulting in the need for manual cleaning of the tank interior, which is complex, labor-intensive, and inconvenient for maintenance, this utility model provides an integrated water tank device for air source heat pump units.

[0005] This utility model is implemented as follows: a water tank device for an integrated air source heat pump unit, comprising: a water tank, a tank cover fixedly installed on the top of the water tank, a water outlet pipe fixedly installed on the water tank, and a first valve provided on the water outlet pipe; a first water pump fixedly installed on one side of the water tank, a water suction pipe fixedly installed on the water inlet end of the first water pump, one end of the water suction pipe extending into the interior of the water tank; a delivery pipe fixedly installed on the drain end of the first water pump, the delivery pipe being used to deliver water into the air source heat pump unit; a return water pipe fixedly installed on the water tank, one end of the return water pipe being connected to the air source heat pump unit; and a cleaning mechanism mounted on the tank cover for cleaning the water tank.

[0013] Compared with related technologies, the water tank device of the integrated air source heat pump unit provided by this utility model has the following beneficial effects:

[0014] In this solution, the controller automatically starts the first water pump when the temperature sensor detects that the water temperature in the tank is lower than the set value. The first water pump then transports water from the tank to the air source heat pump unit for heating through the suction and delivery pipes. After heating, the water is returned to the tank through the return pipe, and the cycle continues until the water temperature reaches the set value, effectively ensuring the water temperature in the tank. By opening the first valve, water from the tank can enter the water supply system, allowing the hot water in the tank to supply water to the user's home appliances. The controller also automatically opens the solenoid valve when the water level is lower than the first level sensor, allowing the water inlet pipe to add water to the tank until the water level reaches the second level sensor. The cleaning mechanism can scrape and clean the contaminants adhering to the inner wall of the tank, replacing manual labor. It can also spray disinfectant while cleaning, achieving cleaning and disinfection of the water tank without manual intervention. This saves time and effort and makes cleaning and maintenance more convenient. Attached Figure Description

The terms "first," "second," etc., in the specification or the foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a water tank device for an integrated air source heat pump unit, such as... Figure 1-4 As shown, the water tank device of the integrated air source heat pump unit includes: a water tank 1, a tank cover 2 fixedly installed on the top of the water tank 1, a water outlet pipe 3 fixedly installed on the water tank 1, and a first valve provided on the water outlet pipe 3; a first water pump 4 fixedly installed on one side of the water tank 1, a water suction pipe 5 fixedly installed on the water inlet end of the first water pump 4, one end of the water suction pipe 5 extending into the interior of the water tank 1; a delivery pipe 6 fixedly installed on the drain end of the first water pump 4, the delivery pipe 6 being used to deliver water into the air source heat pump unit; a return water pipe 7 fixedly installed on the water tank 1, one end of the return water pipe 7 being connected to the air source heat pump unit; and a cleaning mechanism assembled on the tank cover 2 for cleaning the water tank 1.

[0023] In this solution, during use, one end of the delivery pipe 6 needs to be connected to the inlet of the air source heat pump unit, and one end of the return pipe 7 needs to be connected to the outlet of the air source heat pump unit. When the water temperature in the water tank 1 is lower than the set value, the first water pump 4 can transport the water from the water tank 1 to the air source heat pump unit for heating through the pumping pipe 5 and the delivery pipe 6. After heating, the water will be transported back to the water tank 1 through the return pipe 7, circulating repeatedly until the water temperature reaches the set value. The air source heat pump unit is a mature existing technology and is not shown in the diagram. When water from the water tank 1 needs to be used, it is necessary to ensure that the outlet pipe 3 is equipped with a pipe for connecting to the water supply system. This way, simply opening the first valve on the outlet pipe 3 will allow the water in the water tank 1 to be discharged into the water supply system, providing hot water for the user's home appliances. When the inner wall of the water tank 1 needs cleaning, the user can activate the cleaning mechanism to quickly clean the contaminants adhering to the inner wall of the water tank 1 without manual intervention, saving time and effort and making cleaning and maintenance convenient.

[0024] In a further preferred embodiment of this utility model, the cleaning mechanism includes: a three-way pipe 8 rotatably mounted on the cover 2, a U-shaped pipe 12 fixedly mounted on the three-way pipe 8, and brush bristles and a water spray nozzle provided on the U-shaped pipe 12; a servo motor 9 fixedly mounted on the top of the cover 2, a first bevel gear 10 fixedly sleeved on the output shaft of the servo motor 9; a second bevel gear 11 fixedly sleeved on the three-way pipe 8, the second bevel gear 11 meshing with the first bevel gear 10; a storage tank 13 fixedly mounted on the water tank 1 for storing disinfectant water; a second water pump 14 fixedly mounted on the cover 2, a suction pipe 15 fixedly mounted on the pump end of the second water pump 14, one end of the suction pipe 15 extending into the interior of the storage tank 13; and a discharge pipe 16 fixedly mounted on the drain end of the second water pump 14, one end of the discharge pipe 16 rotatably connected to the top end of the three-way pipe 8.

[0025] In this embodiment, the cleaning mechanism is used to clean the water tank 1. During use, the servo motor 9 and the second water pump 14 are started simultaneously. The servo motor 9 drives the first bevel gear 10 to rotate, which in turn drives the second bevel gear 11 to rotate. The second bevel gear 11 drives the three-way pipe 8 to rotate on the tank cover 2, and the three-way pipe 8 drives the U-shaped pipe 12 to rotate, so that the bristles on the U-shaped pipe 12 can scrape and clean the inner wall of the water tank 1. The second water pump 14 transfers the disinfectant water in the storage tank 13 to the discharge pipe 16 through the suction pipe 15. The discharge pipe 16 delivers the disinfectant water to the three-way pipe 8, and then from the three-way pipe 8 into the U-shaped pipe 12, and finally sprays it out from the spray nozzle of the U-shaped pipe 12. Thus, with the cooperation of the bristles, the cleaning effect on the water tank 1 can be further improved, and the contaminants attached to the inner wall of the water tank 1 can be effectively removed, making cleaning more convenient.

[0026] In a further preferred embodiment of the present invention, a sewage pipe 17 for discharging sewage is fixedly installed at the bottom of the water tank 1, and a second valve is provided on the sewage pipe 17.

[0027] In this embodiment, by opening the second valve, the cleaned-up contaminants and the liquid mixed with the contaminants can be discharged from the drain pipe 17.

[0028] In a further preferred embodiment of this utility model, both the delivery pipe 6 and the return pipe 7 are equipped with one-way valves, and the bottom of the water tank 1 is fixedly installed with support legs.

[0029] In this embodiment, the use of a one-way valve can prevent backflow of water in the delivery pipe 6 and the return pipe 7.

[0030] In a further preferred embodiment of the present invention, a water injection pipe 23 for adding water is fixedly installed on the water tank 1, and a solenoid valve is provided on the water injection pipe 23.

[0031] In this embodiment, by using the water injection pipe 23 and the solenoid valve together, it is convenient to add an appropriate amount of water to the water tank 1 when the liquid level in the water tank 1 drops. The water injection pipe 23 can be connected to a faucet through a corresponding pipe. The faucet needs to be normally open. In this way, when water needs to be added, as long as the solenoid valve is opened, the water injection pipe 23 can inject water into the water tank 1.

[0032] In a further preferred embodiment of the present invention, a first cover 18 is fixedly installed on one side of the water tank 1, and a first liquid level sensor 19 and a temperature sensor 20 are fixedly installed on the first cover 18. A second cover 21 is fixedly installed on one side of the water tank 1, and a second liquid level sensor 22 is fixedly installed on the second cover 21. The second liquid level sensor 22 is located above the first liquid level sensor 19.

[0033] In this embodiment, the liquid level in the water tank 1 can be detected by the cooperation of the first liquid level sensor 19 and the second liquid level sensor 22. The first liquid level sensor 19 and the second liquid level sensor 22 are model RK-PM200. The water temperature in the water tank 1 can be detected by the use of the temperature sensor 20, model 103F3950-500.

[0034] In a further preferred embodiment of the present invention, an addition tube for adding disinfectant is fixedly installed on the top of the storage box 13, and a cover is threaded onto the addition tube.

[0035] In this embodiment, the cover is opened from the adding tube by rotating it, which makes it convenient for personnel to add disinfectant water into the storage box 13 through the adding tube.

[0036] In a further preferred embodiment of this utility model, a controller is fixedly installed on one side of the water tank 1, and the brush bristles are in contact with the inner wall of the water tank 1.

[0037] In this embodiment, the controller enables the device to automatically open and close the solenoid valve on the water injection pipe 23 according to the water level, thereby achieving automatic water replenishment. It can also open and close the first water pump 4 according to the water temperature, so that when the water temperature is low, it can be delivered to the air source heat pump unit for heating. The controller model is FX3U-M26MT, which belongs to the prior art, and its principle will not be described here.

[0038] In summary, compared with related technologies, this solution, through the use of a controller, can automatically start the first water pump 4 when the temperature sensor 20 detects that the temperature in water tank 1 is lower than the set value. The first water pump 4 then transports water from water tank 1 to the air-source heat pump unit for heating via the suction pipe 5 and delivery pipe 6. After heating, the water is returned to water tank 1 via the return pipe 7, circulating repeatedly until the water temperature reaches the target, effectively ensuring the water temperature in water tank 1. By opening the first valve, water from water tank 1 can enter the water supply system, ensuring the water temperature in water tank 1... Hot water can be supplied to the water-using equipment in the user's home. With the use of the controller, the solenoid valve can be automatically opened when the water level is lower than the first liquid level sensor 19, so that the water injection pipe 23 can add water to the water tank 1 until the water level contacts the second liquid level sensor 22. With the use of the cleaning mechanism, the contaminants attached to the inner wall of the water tank 1 can be scraped and cleaned instead of manually. Disinfectant can be sprayed at the same time, so the cleaning and disinfection of the water tank 1 can be carried out without manual operation, which is more time-saving and labor-saving, and the cleaning and maintenance are more convenient.

[0039] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
