Description

Technical Field

[0001] This utility model relates to the field of air source water heater technology, and in particular to an evaporator cover structure for an air source water heater. Background Technology

[0002] Air source heat pump water heaters, as energy-efficient and high-performance water heating devices, are widely used in both residential and commercial sectors due to their advantage of utilizing air heat energy conversion. The evaporator is the core heat exchange component of an air source heat pump water heater, and its operating status directly affects the heating efficiency and lifespan of the water heater. Therefore, it needs to be protected by a cover structure to ensure its stable operation.

[0003] However, the existing evaporator cover structure of air source water heaters has obvious shortcomings: First, the protective function is limited, and it can only provide simple cover, which is difficult to effectively block dust and debris. Long-term use can easily cause dust and scale to accumulate on the evaporator, reducing heat exchange efficiency. Second, there is a lack of convenient maintenance and cleaning mechanisms. When it is necessary to clean or repair the evaporator or cover, the disassembly and installation operations are cumbersome, time-consuming and labor-intensive.

[0004] Therefore, we propose an evaporator cover structure for an air source water heater. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies. The evaporator cover structure of existing air source water heaters has obvious deficiencies: First, the protective function is limited, only providing simple shielding and failing to effectively block dust and debris. Long-term use can easily lead to dust and scale buildup on the evaporator, reducing heat exchange efficiency. Second, there is a lack of convenient maintenance and cleaning mechanisms. When it is necessary to clean or repair the evaporator or cover, the disassembly and installation operations are cumbersome, time-consuming, and labor-intensive.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An evaporator cover structure for an air source water heater includes an air source water heater body, an evaporator body at the connection of the air source water heater body, a protective cover structure on the outside of the evaporator body, a maintenance mechanism inside the protective cover structure and located on the front and back sides, and a plurality of locking structures on the right side wall of the protective cover structure.

[0008] The protective cover structure is used to protect the evaporator body;

[0009] The maintenance mechanism includes two cleaning structures and an air supply structure. The air supply structure is used to supply air to the two cleaning structures, thereby achieving the cleaning of the protective cover structure.

[0010] As a preferred embodiment of this utility model, the protective cover structure includes a protective frame, and the bottom of the protective frame and both the front and back sides are provided with mounting limiting grooves. The interior of each of the two mounting limiting grooves is provided with a protective cover body, the interior of each of the two protective cover bodies is provided with a filter screen, and the right side wall of each of the two protective cover bodies is provided with a locking element.

[0011] As a preferred embodiment of this utility model, the protective cover body is slidably connected inside the installation limiting groove, the filter screen is used to block dust, and the locking component is used to connect the locking structure, thereby realizing the locking of the protective cover body.

[0012] As a preferred embodiment of this utility model, the air supply structure includes a fixed base, an air pump is provided on the top of the fixed base, a connecting pipe is provided at the output end of the air pump, a connecting member is provided at the connection of the connecting pipe, and an air supply pipe is provided on the top of the connecting member.

[0013] As a preferred embodiment of this utility model, the cleaning structure includes a connecting hose, the top of which is connected to an air supply pipe, the bottom of which is provided with a jet seat, the outer surface of which is provided with a plurality of jet nozzles, and the two side walls of which are respectively provided with a lead screw and a linear optical axis, and the top of which is provided with a drive motor.

[0014] In a preferred embodiment of this utility model, the jet seat is connected to the air supply pipe via a connecting hose, and the drive motor is used to drive the lead screw to rotate, thereby causing the jet seat to slide.

[0015] As a preferred embodiment of this utility model, the locking structure includes a rotating shaft, a connecting cap is provided on the side wall of the rotating shaft, and a locking rod is provided at the connection point of the connecting cap.

[0016] As a preferred embodiment of this utility model, the connecting cap rotates via a rotating shaft, causing the locking rod to rotate into the interior of the locking component, thereby locking the protective cover structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this utility model, the protective cover structure is equipped with a protective cover body with a filter screen, which can effectively block dust and debris, prevent dust and scale buildup on the evaporator, ensure the heat exchange efficiency of the evaporator, extend its service life, and solve the problems of the traditional cover's single protective function and the evaporator's susceptibility to contamination.

[0019] The air supply and cleaning structures of the maintenance mechanism work together. The air pump supplies air through the nozzle of the jet seat to automatically clean the protective cover. The drive motor drives the jet seat to slide to achieve a thorough cleaning. At the same time, the protective cover body can be slidably installed and removed, which greatly simplifies the maintenance and repair process and solves the problem of cumbersome maintenance and cleaning of traditional structures.

[0020] The locking structure uses a rotating shaft and connecting cap to drive the locking rod to engage with the locking component, ensuring a secure locking mechanism. This prevents loosening caused by long-term use or external factors, ensuring that the protective cover continuously and stably protects the evaporator, thus solving the problem of poor stability in traditional locking structures.

[0031] Example

[0032] like Figure 1-5 As shown, this utility model provides a technical solution: an evaporator cover structure for an air source water heater, including an air source water heater body 10, an evaporator body 20 at the connection of the air source water heater body 10, a protective cover structure 30 on the outside of the evaporator body 20, a maintenance mechanism 40 inside the protective cover structure 30 and located on the front and back sides, and a plurality of locking structures 50 on the right side wall of the protective cover structure 30; the protective cover structure 30 is used to protect the evaporator body 20; the maintenance mechanism 40 includes two cleaning structures and an air supply structure, the air supply structure is used to supply air to the two cleaning structures, thereby realizing the cleaning of the protective cover structure 30.

[0033] When the air source water heater is running, the evaporator body 20 exchanges heat energy. The protective cover structure 30 covers the evaporator body 20 from the outside, preventing external dust and debris from directly contacting it. After the gas supply structure of the maintenance mechanism 40 is activated, the gas is delivered to the two cleaning structures. The cleaning structures use gas power to blow and clean the dust on the surface and inside of the protective cover structure 30, thereby achieving protection while conveniently cleaning and maintaining the protective cover, ensuring the long-term efficient operation of the evaporator.

[0034] The protective cover structure 30 includes a protective frame 301. The bottom of the protective frame 301 and both the front and back sides are provided with mounting limiting grooves 302. The two mounting limiting grooves 302 are each provided with a protective cover body 303. The two protective cover bodies 303 are each provided with a filter screen 304. The right side wall of the two protective cover bodies 303 is provided with a locking element 305.

[0035] The protective frame 301 provides support for the entire protective cover structure 30. The mounting limiting groove 302 plays a sliding guiding and limiting role for the protective cover body 303, allowing the protective cover body 303 to be smoothly installed and removed along the mounting limiting groove 302. The filter screen 304 inside the protective cover body 303 can effectively intercept dust particles in the air and prevent them from entering the evaporator area. The locking part 305 on the right side wall cooperates with the locking structure 50 to fix the protective cover body 303, which structurally ensures the protection of the evaporator and facilitates disassembly and maintenance. At the same time, the filter screen 304 improves the precision of protection.

[0036] The protective cover body 303 is slidably connected inside the mounting limit groove 302. The filter screen 304 is used to block dust, and the locking component 305 is used to connect the locking structure 50, thereby realizing the locking of the protective cover body 303.

[0037] The protective cover body 303 can be easily pulled out or pushed in during maintenance and repair through sliding cooperation with the installation limiting groove 302, making operation convenient; the filter screen 304 blocks dust and other impurities on the outside when air flows through it, keeping the air entering the evaporator area clean; when the locking part 305 is connected to the locking structure 50, the protective cover body 303 is firmly fixed to the protective frame 301 through structural engagement or locking action, preventing it from loosening or shifting, ensuring continuous and effective protection of the evaporator, and facilitating locking and unlocking operations during disassembly and assembly.

[0038] The air supply structure includes a fixed base 401, an air pump 402 is provided on the top of the fixed base 401, a connecting pipe 403 is provided at the output end of the air pump 402, a connecting member 404 is provided at the connection of the connecting pipe 403, and an air supply pipe 405 is provided on the top of the connecting member 404.

[0039] The fixed base 401 provides stable support for the air pump 402, ensuring that the air pump 402 remains stable during operation. After the air pump 402 is started, it draws in and compresses outside air to form an airflow with a certain pressure, which is then transported to the connecting member 404 via the connecting pipe 403. The connecting member 404 distributes the airflow to the air supply pipe 405, which in turn transports the airflow to the cleaning structure, providing continuous gas power to the cleaning structure and enabling air blowing cleaning of the protective cover structure 30, ensuring the continuous effectiveness of the cleaning function.

[0040] The cleaning structure includes a connecting hose 406, the top of which is connected to an air supply pipe 405. The bottom of the air supply pipe 405 is provided with a jet seat 407. Several jet nozzles 408 are provided on the outer surface of the jet seat 407. A lead screw 409 and a linear optical axis 410 are respectively provided on the two side walls of the jet seat 407. A drive motor 411 is provided on the top of the lead screw 409.

[0041] The connecting hose 406 is flexible and can move and deform flexibly with the jet seat 407, ensuring a continuous and stable airflow between the air supply pipe 405 and the jet seat 407. After the air supply pipe 405 delivers the airflow to the jet seat 407, the airflow is ejected from several jet nozzles 408, forming a multi-directional blowing airflow to thoroughly clean the protective cover structure 30. The drive motor 411 starts and drives the lead screw 409 to rotate. The lead screw 409 cooperates with the jet seat 407 to make the jet seat 407 slide up and down along the guide direction of the linear optical axis 410, so that the jet nozzles 408 blow on different height areas of the protective cover structure 30, achieving all-round cleaning and ensuring that the dust on the surface of the protective cover structure 30 and the filter screen 304 is completely removed, thus ensuring the heat exchange environment of the evaporator.

[0042] The jet mount 407 is connected to the air supply pipe 405 via a connecting hose 406. The drive motor 411 drives the lead screw 409 to rotate, thereby causing the jet mount 407 to slide.

[0043] The connection method of the connecting hose 406 ensures that the airflow channel between the air supply pipe 405 and the jet seat 407 remains unobstructed during the up-and-down sliding process of the jet seat 407, preventing airflow interruption or poor delivery due to the movement of the jet seat 407. The drive motor 411 outputs power to drive the lead screw 409 to rotate. The threaded structure of the lead screw 409 engages with the internal thread of the jet seat 407, converting the rotation of the lead screw 409 into linear motion of the jet seat 407. At the same time, the linear optical axis 410 guides and supports the jet seat 407, enabling the jet seat 407 to slide stably up and down, driving the jet nozzle 408 to blow and clean different parts of the protective cover structure 30, achieving a comprehensive cleaning effect.

[0044] The locking structure 50 includes a rotating shaft 501, a connecting cap 502 on the side wall of the rotating shaft 501, and a locking rod 503 at the connection point of the connecting cap 502.

[0045] The rotating shaft 501 provides a fulcrum for the connecting cap 502. When it is necessary to lock the protective cover structure 30, the connecting cap 502 is rotated, which drives the locking rod 503 to rotate, so that the locking rod 503 engages with the locking piece 305 on the protective cover structure 30. Through the structural cooperation between the locking rod 503 and the locking piece 305, the protective cover structure 30 is locked to prevent it from loosening and to ensure the continuous protection of the evaporator by the protective cover structure 30. Moreover, the locking and unlocking operations only require rotating the connecting cap 502, which is simple and quick.

[0046] The connecting cap 502 rotates via the rotating shaft 501, causing the locking rod 503 to rotate into the locking member 305, thereby locking the protective cover structure 30.

[0047] When the connecting cap 502 rotates around the rotating shaft 501, its side wall connecting structure drives the locking rod 503 to rotate synchronously. When the locking rod 503 rotates into the locking member 305, it engages or embeds with the internal structure of the locking member 305, firmly fixing the protective cover structure 30 onto the protective frame 301, preventing it from shifting or falling off due to vibration or other factors during the operation of the water heater, and ensuring continuous and stable protection of the evaporator. When disassembly and maintenance are required, the connecting cap 502 can be rotated in the opposite direction to disengage the locking rod 503 from the locking member 305, achieving convenient unlocking.

[0048] Workflow

[0049] During the operation of the air source water heater, the evaporator body 20 exchanges heat energy. The protective cover body 303 of the protective cover structure 30 is slidably installed in the protective frame 301 through the installation limiting groove 302. The filter screen 304 inside it blocks external dust and debris, preventing direct contact with the evaporator body 20. At the same time, the connecting cap 502 of the locking structure 50 rotates around the rotating shaft 501, driving the locking rod 503 to engage with the locking part 305 of the protective cover body 303, thereby locking the protective cover body 303 and structurally providing stable protection for the evaporator body 20.

[0050] When the protective cover structure 30 needs cleaning, the air pump 402 of the air supply structure starts, draws in and compresses air, and delivers it to the air supply pipe 405 through the connecting pipe 403 and the connecting piece 404. The air supply pipe 405 delivers the airflow to the jet seat 407 through the connecting hose 406. The airflow is sprayed out from the multiple jet nozzles 408 of the jet seat 407 to blow clean the surface of the protective cover body 303 and the filter screen 304. At the same time, the drive motor 411 drives the lead screw 409 to rotate. The lead screw 409 cooperates with the jet seat 407 to make the jet seat 407 slide up and down along the linear optical axis 410, thereby achieving all-round cleaning of different height areas of the protective cover body 303, ensuring that dust is effectively removed and ensuring the heat exchange efficiency of the evaporator.

[0051] If the evaporator body 20 or the protective cover structure 30 needs to be inspected during disassembly and maintenance, first rotate the connecting cap 502 of the locking structure 50 to disengage the locking rod 503 from the locking member 305 around the rotating shaft 501, thus releasing the lock on the protective cover body 303; then pull the protective cover body 303 out along the installation limiting groove 302 to perform the inspection operation; after the inspection is completed, slide the protective cover body 303 into the installation limiting groove 302, and then rotate the connecting cap 502 to engage the locking rod 503 with the locking member 305 to complete the locking and restore the protective state.
