Description

Technical Field

[0001] The utility model relates to the technical field of air energy water heaters, in particular to an air energy water heater with a descaling device. Background Art

[0002] An air-energy water heater is a device that uses the working principle of a heat pump to absorb heat from the air to produce hot water. The air-energy water heater transfers heat from the environment to the water by allowing the refrigerant to continuously complete the thermal cycle of evaporation, compression, condensation, throttling, and re-evaporation.

[0003] Existing air-energy water heaters with descaling devices generally use a separate sewage outlet for sewage discharge. When cleaning, it is necessary to inject chemicals into the water heater, and after a period of time, pour out the liquid. In addition, high-pressure water cleaning can be used. The heat exchange tubes need to be repeatedly flushed from the hot water outlet and the cold water inlet, and the high-pressure water pipes need to be repeatedly plugged and unplugged, which is inconvenient. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an air-energy water heater with a descaling device to solve the inconvenience of repeatedly plugging and unplugging high-pressure water pipes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air-energy water heater with a descaling device, comprising a box body, one side of the box body is fixedly connected to the descaling device, the descaling device comprises an upper three-way ball valve and a lower three-way ball valve, an operating rod is arranged between the upper three-way ball valve and the lower three-way ball valve, one side of the upper three-way ball valve and the lower three-way ball valve is fixedly connected to a water inlet pipe, and one end of the water inlet pipe is fixedly connected to an interface.

[0006] By adopting the above technical solution, the descaling device fixedly connected to one side of the box body allows the user to easily control the path and direction of the water flow through the flexible operation of the upper three-way ball valve and the lower three-way ball valve, thereby thoroughly cleaning the inside of the water heater, simplifying the tedious steps in the traditional cleaning process and improving the cleaning efficiency.

[0007] Furthermore, one side of the upper three-way ball valve is fixedly connected to an upper nozzle, and one side of the lower three-way ball valve is fixedly connected to a lower nozzle.

[0008] By adopting the above technical solution, the air-energy water heater with a descaling device is firstly optimized in structure. The upper nozzle pipe fixedly connected to one side of the upper three-way ball valve and the lower nozzle pipe fixedly connected to one side of the lower three-way ball valve form a cleaning path in the upper and lower directions, ensuring the comprehensiveness of the cleaning and improving the descaling effect.

[0009] Furthermore, a heat exchange tube is arranged inside the box, an external machine is arranged on one side of the box, and the external machine and the heat exchange tube are connected through a conduit.

[0010] By adopting the above technical solution, the heat exchange tubes arranged inside the box are the core components of the water heater, which are responsible for transferring heat energy to water, thereby heating the water, while the external unit arranged on one side of the box is connected to the heat exchange tubes through a conduit, forming a heat energy transfer system of the air-energy water heater.

[0011] Furthermore, a water return port is fixedly connected to one side of the top of the box body, and a water outlet is fixedly connected to one side of the bottom of the box body.

[0012] By adopting the above technical solution, the setting of the return water port makes it easy for the water heater to realize water recycling. When the user needs to use hot water, the hot water flows out from the water outlet, and the used water can re-enter the water heater through the return water port for heating, thereby realizing the effective utilization of water resources and reducing waste.

[0013] Furthermore, the upper nozzle and the lower nozzle are fixedly connected to the box.

[0014] By adopting the above technical solution, this fixed connection method enhances the stability of the upper nozzle and the lower nozzle. Since they are directly connected to the box body, they will not shake or shift during the cleaning process, thereby ensuring the accuracy and effectiveness of cleaning.

[0015] Furthermore, the upper nozzle and one side of the heat exchange tube are arranged opposite to each other, and the other side of the heat exchange tube of the lower nozzle is arranged opposite to each other.

[0016] By adopting the above technical solution, this layout enables the upper nozzle and the lower nozzle to directly aim at the two sides of the heat exchange tube for high-pressure water spraying. Since the relative positions of the nozzle and the heat exchange tube correspond precisely, the high-pressure water can accurately impact the scale and dirt on the surface of the heat exchange tube, thereby achieving a more thorough and effective cleaning effect.

[0017] Furthermore, the heat exchange tube has a spiral structure.

[0018] By adopting the above technical solution, the spiral structure of the heat exchange tube increases its surface area, thereby improving the heat exchange efficiency with water. Compared with the traditional straight tube heat exchange tube, the spiral structure can provide a larger heat exchange area in a limited space, so that the water heater can heat water faster and improve the overall working efficiency.

[0019] Furthermore, a protective cover is provided on the outer side of the operating rod, and the material of the protective cover is rubber.

[0020] By adopting the above technical solution, the provision of the protective cover increases the comfort of holding the operating rod. Since the protective cover is made of rubber material, it is soft and has a certain elasticity, so that the user can feel more comfortable when holding the operating rod to rotate, reducing the discomfort of the hand.

[0021] Furthermore, one end of the interface is fixedly connected to a shell, and a mounting groove is provided inside the shell.

[0022] By adopting the above technical solution, the design of the shell provides additional protection for the interface, and the fixed connection of the shell increases the stability of the interface, preventing accidental collision or damage, thereby ensuring the smooth progress of the cleaning process.

[0023] Furthermore, a loading box is slidably connected to the interior of the mounting groove, and a receiving chamber is provided inside the loading box.

[0024] By adopting the above technical solution, the sliding connection mode of the loading box makes it easy to take it out or put it in the installation slot, which improves the convenience of adding and replacing the cleaning agent. The user can easily complete the task of replenishing the cleaning agent without complicated operations or professional tools.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model is provided with a water inlet pipe, an interface, an upper three-way ball valve and a lower three-way ball valve. By operating the two ball valves, the user can easily control the path and direction of the water flow to achieve cleaning of different areas inside the water heater, which not only simplifies the cleaning steps, but also improves the cleaning effect, bringing great convenience to the user;

[0027] 2. The utility model provides an additional protective layer for the operating rod by setting a protective cover, effectively preventing the operating rod from being damaged by friction, collision or corrosion during use, extending the service life of the operating rod, and reducing the frequency of maintenance and replacement, saving costs and time for users;

[0028] 3. The utility model provides a housing, a mounting slot, a loading box and a receiving chamber. The receiving chamber inside the loading box provides a user with a special storage space for accommodating cleaning agents or other necessary maintenance materials, which helps to keep the equipment clean and running efficiently.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] An air energy water heater with a descaling device, such as Figure 1-Figure 4 As shown, it includes a box body 1, one side of the box body 1 is fixedly connected to a descaling device 2, the descaling device 2 includes an upper three-way ball valve 201 and a lower three-way ball valve 202, an operating rod 203 is arranged between the upper three-way ball valve 201 and the lower three-way ball valve 202, one side of the upper three-way ball valve 201 and the lower three-way ball valve 202 is fixedly connected to a water inlet pipe 204, one end of the water inlet pipe 204 is fixedly connected to an interface 205, the descaling device 2 fixedly connected to one side of the box body 1 is connected to the upper three-way ball valve 201 and the lower three-way ball valve 202 through the operating rod 203. The flexible operation of 02 allows the user to easily control the path and direction of the water flow, thereby thoroughly cleaning the inside of the water heater, simplifying the tedious steps in the traditional cleaning process and improving the cleaning efficiency. At the same time, the technical solution further improves the convenience of user operation by setting an operating lever 203. The user only needs to turn the operating lever 203 to simultaneously control the switching status of the upper three-way ball valve 201 and the lower three-way ball valve 202, without having to operate the two ball valves separately, thereby saving time and energy.

[0038] See also Figure 2 and Figure 3An upper nozzle 206 is fixedly connected to one side of the upper three-way ball valve 201, and a lower nozzle 207 is fixedly connected to one side of the lower three-way ball valve 202. The air-energy water heater with a descaling device is firstly optimized in structure. The upper nozzle 206 fixedly connected to one side of the upper three-way ball valve 201 and the lower nozzle 207 fixedly connected to one side of the lower three-way ball valve 202 form a cleaning path in the upper and lower directions, ensuring the comprehensiveness of the cleaning and improving the descaling effect. At the same time, high-pressure water is sprayed simultaneously through the upper nozzle 206 and the lower nozzle 207, which can evenly cover the surface of the heat exchange tube, ensuring that each part can be fully cleaned and improving the cleaning efficiency.

[0039] See also Figure 2 and Figure 3 A heat exchange tube 4 is arranged inside the box body 1, and an external unit 5 is arranged on one side of the box body 1. The external unit 5 and the heat exchange tube 4 are connected through a conduit 12. The heat exchange tube 4 arranged inside the box body 1 is the core component of the water heater, which is responsible for transferring heat energy to water, thereby heating the water. The external unit 5 arranged on one side of the box body 1 is connected with the heat exchange tube 4 through the conduit 12, forming a heat energy transfer system of the air-energy water heater. At the same time, the connection method of the conduit 12 also ensures smooth and stable heat energy transfer, and can smoothly transfer the heat energy generated by the external unit 5 to the heat exchange tube 4, avoiding the loss and waste of heat energy, and ensuring the stability and reliability of its operation.

[0040] See also Figure 1 , Figure 2 and Figure 3 A return water port 6 is fixedly connected to one side of the top of the box body 1, and a water outlet 7 is fixedly connected to one side of the bottom of the box body 1. The setting of the return water port 6 allows the water heater to easily realize water recycling. When the user needs to use hot water, the hot water flows out from the water outlet 7, and the used water can re-enter the water heater through the return water port 6 for heating, thereby realizing the effective utilization of water resources and reducing waste. At the same time, the water outlet 7 is located on the bottom side of the box body 1, ensuring that the user can always obtain hot water at a higher temperature when using it.

[0041] See also Figure 3 The upper nozzle 206 and the lower nozzle 207 are fixedly connected to the housing 1. This fixed connection method enhances the stability of the upper nozzle 206 and the lower nozzle 207. Since they are directly connected to the housing 1, they will not shake or shift during the cleaning process, thereby ensuring the accuracy and effectiveness of the cleaning. At the same time, the fixed connection also simplifies the overall structure of the water heater. The upper nozzle 206 and the lower nozzle 207 are part of the descaling device, and the fixed connection with the housing 1 makes the entire device more compact and integrated, which not only facilitates installation and maintenance, but also improves the overall aesthetics of the water heater.

[0042] See also Figure 2The upper nozzle 206 is arranged opposite to one side of the heat exchange tube 4, and the lower nozzle 207 is arranged opposite to the other side of the heat exchange tube 4. This layout allows the upper nozzle 206 and the lower nozzle 207 to directly aim at the two sides of the heat exchange tube 4 for high-pressure water spraying. Since the relative positions of the nozzles and the heat exchange tube 4 are precisely corresponding, the high-pressure water can accurately impact the scale and dirt on the surface of the heat exchange tube, thereby achieving a more thorough and effective cleaning effect. At the same time, the upper nozzle 206 and the lower nozzle 207 spray from both sides of the heat exchange tube 4 respectively, so that the entire surface of the heat exchange tube can be evenly covered by water flow, avoiding the problem of insufficient or excessive cleaning of certain areas, thereby extending the service life of the heat exchange tube.

[0043] See also Figure 2 and Figure 3 The heat exchange tube 4 has a spiral structure. The spiral structure of the heat exchange tube 4 increases its surface area, thereby improving the heat exchange efficiency with water. Compared with the traditional straight tube heat exchange tube, the spiral structure can provide a larger heat exchange area in a limited space, so that the water heater can heat water faster and improve the overall working efficiency. At the same time, the spiral structure also helps to enhance the structural strength of the heat exchange tube 4. Since the heat exchange tube needs to withstand certain pressure and temperature changes during operation, the design of the spiral structure can better disperse and withstand these stresses, thereby extending the service life of the heat exchange tube.

[0044] See also Figure 1 The outer side of the operating rod 203 is provided with a protective cover 3, and the material of the protective cover 3 is rubber. The setting of the protective cover 3 increases the comfort of holding the operating rod 203. Since the protective cover 3 is made of rubber, it is soft and has a certain elasticity, so that the user can feel a more comfortable hand feel when holding the operating rod for rotation, reducing the discomfort of the hand. At the same time, the rubber protective cover 3 also has good anti-slip performance. During the cleaning process, slippery substances such as water droplets or scale may remain inside the water heater, and the rubber protective cover 3 can effectively increase friction, preventing the user from making operating errors or getting injured due to hand slipping during operation.

[0045] The implementation principle of the utility model is as follows: first, the operating lever 203 is rotated so that the upper three-way ball valve 201 connects the upper nozzle 206 with the water inlet pipe 204, and at this time, the lower three-way ball valve 202 connects the lower nozzle 205 with the outside, and then the interface 205 is connected to high-pressure water, and at this time, the high-pressure water enters the upper nozzle 206 from the water inlet pipe 204, and then one side of the heat exchange tube 4 is flushed, and the scale flushed flows out from the lower nozzle 205 to the outside, and then the operating lever 203 is rotated again, and at this time, the upper three-way ball valve 201 connects the upper nozzle 206 with the outside, and then the lower three-way ball valve 202 connects the lower nozzle 205 with the water inlet pipe 204, so that the high-pressure water enters the lower nozzle 205 from the water inlet pipe 204, and then the other side of the heat exchange tube 4 is flushed, thereby improving the flushing efficiency.

[0046] Embodiment 2:

[0047] See also Figure 4 One end of the interface 205 is fixedly connected to the shell 8, and a mounting groove 9 is provided inside the shell 8. The design of the shell 8 provides additional protection for the interface 205. The fixed connection of the shell 8 increases the stability of the interface 205 and prevents accidental collision or damage, thereby ensuring the smooth progress of the cleaning process. At the same time, the opening of the mounting groove 9 facilitates the connection of the interface 205. The user can easily insert the connecting end of the high-pressure water pipe into the mounting groove 9 and tightly connect it with the interface 205, thereby avoiding shaking or falling off of the water pipe during the cleaning process.

[0048] See also Figure 4 The mounting groove 9 is internally slidably connected with a loading box 10, and a receiving chamber 11 is provided inside the loading box 10. The sliding connection mode of the loading box 10 allows it to be conveniently taken out or put in from the mounting groove 9, which improves the convenience of adding and replacing the cleaning agent. The user can easily complete the task of replenishing the cleaning agent without complicated operations or professional tools. At the same time, the opening of the receiving chamber 11 provides sufficient storage space for the loading box 10, so that the cleaning agent can be evenly contained therein, ensuring a stable supply of cleaning agent during the cleaning process.

[0049] The implementation principle of the utility model is: first, rotate the operating lever 203 to close the upper three-way ball valve 201 and the lower three-way ball valve 202, pull the loading box 10 outward, fill the inside of the accommodating chamber 11 with flushing solution, and then install high-pressure water on one side of the shell 8 to achieve flushing and soaking using high-pressure water of the mixed solution.
