[0031] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-7 As shown, a weather-resistant air source heat pump water heater includes an outer tank, a water storage tank, and a thermal circulation system. The water storage tank and the thermal circulation system are located inside the outer tank. The thermal circulation system has the same structural principle as the thermal circulation system of existing air source heat pump water heaters. The water storage tank includes a tank body 101, a top plate 104, a bottom plate 102, and several side plates 107. The top plate 104 and the bottom plate 102 are detachably connected to the tank body 101, and the side plates 107 are concealed on the inner wall of the tank body 101. When the bottom plate 102 or the top plate 104 is removed from the tank body 101, the side plates 107 can be removed from the tank body 101. The outer tank is coated with a weather-resistant powder coating. The coating of the weather-resistant powder coating enables the outer tank to maintain good performance in different climatic environments, effectively preventing corrosion and aging problems caused by long-term exposure to air, and extending the service life of the outer tank. The side panel 107 forms a complete shielding layer on the inner wall of the tank 101, which can reduce the direct adhesion of scale and other impurities to the tank 101. The bottom plate 102, top plate 104, and side panel 107 can all be disassembled and cleaned individually, making it easier to clean the scale inside the water tank.

[0033] Furthermore, the base plate 102 is provided with a connecting plate 103, and the side wall of the housing 101 is provided with a first connecting groove, in which a connecting strip 116 is provided. The connecting plate 103 is provided with a second connecting groove corresponding to the connecting strip 116. Both the first and second connecting grooves are T-shaped structures, and the connecting strip 116 is an I-shaped structure. The length of the first connecting groove is much greater than the length of the second connecting groove, and the length of the connecting strip 116 corresponds to the length of the second connecting groove. When it is necessary to disassemble the base plate 102, since the length of the first connecting groove is much greater than the length of the second connecting groove, the base plate 102 can be easily removed from the housing 101 by simply sliding the base plate 102 a certain distance along the direction of the first connecting groove to allow the connecting strip 116 to disengage from the second connecting groove. During installation, the second connecting groove on the base plate 102 is aligned with the connecting strip 116 in the first connecting groove, and then the base plate 102 is slid along the first connecting groove to allow the connecting strip 116 to engage with the second connecting groove, thus completing the installation of the base plate 102.

[0034] Furthermore, a baffle is provided at one end of the connecting plate 103, which abuts against one end of the second connecting groove. A connecting piece is provided on the baffle, which is connected to the connecting plate 103 by screws. The baffle and connecting piece further enhance the stability of the connection between the base plate 102 and the housing 101. When the connecting strip 116 is inserted into the second connecting groove, the baffle is abutted against one end of the second connecting groove, and the connecting piece is fixed to the connecting plate 103 by screws. This prevents the connecting strip 116 from accidentally slipping out of the second connecting groove during use, ensuring the reliability of the connection between the base plate 102 and the housing 101.

[0035] The base plate 102 is provided with connecting plates 103 on both sides, and the two connecting plates 103 are staggered to make the forces on both sides of the base plate 102 symmetrical and improve the connection effect of the base plate 102.

[0036] Furthermore, the bottom of the tank body 101 is provided with an extension 115, and the bottom plate 102 is provided with a first connecting groove corresponding to the extension 115, and a second connecting groove corresponding to the side plate 107. The extension 115 at the bottom of the tank body 101 cooperates with the corresponding first connecting groove on the bottom plate 102, further enhancing the sealing and stability of the connection between the bottom plate 102 and the tank body 101. When the bottom plate 102 is installed on the tank body 101, the extension 115 is embedded in the first connecting groove, which can effectively prevent water from seeping out from the connection between the bottom plate 102 and the tank body 101, ensuring the normal use of the water storage tank.

[0037] The second connecting groove on the base plate 102, corresponding to the side plate 107, facilitates the installation and positioning of the side plate 107. The bottom of the side plate 107 can be inserted into the second connecting groove, allowing the side plate 107 to be firmly fixed to the base plate 102, while also ensuring the fit between the side plate 107 and the inner wall of the tank body 101. When installing the side plate 107, first insert the side plate 107 into the second connecting groove of the base plate 102 in sequence, and then install the top plate 104 on the tank body 101, thus completing the assembly of the entire water storage tank.

[0038] The top plate 104 has the same structure as the bottom plate 102. The connection method between the top plate 104 and the tank 101 is the same as the connection method between the bottom plate 102 and the tank 101. After removing the top plate 104 or the bottom plate 102 from the tank 101, a specific side plate 107 can be cleaned separately to avoid the accumulation of scale on the side plate 107 and facilitate the cleaning of the inside of the water tank.

[0039] Furthermore, the side panel 107 includes a first side panel 1071 and a second side panel 1072. The first side panel 1071 has a connecting block 1073 on its side wall, and the second side panel 1072 has a third connecting groove corresponding to the connecting block 1073 on its side wall. Both the connecting block 1073 and the third connecting groove are T-shaped structures. The first side panel 1071 and the second side panel 1072 are tightly connected through the cooperation of the connecting block 1073 and the third connecting groove. This connection method allows multiple side panels 107 to be spliced ​​into a complete shielding layer, covering the inner wall of the housing 101. During installation, simply align the connecting block 1073 of the first side panel 1071 with the third connecting groove of the second side panel 1072 and gently push it in to complete the connection of the two side panels 107. Moreover, this connection method also has a certain degree of flexibility; when one side panel 107 is damaged, it can be easily removed from the whole assembly for replacement without affecting the installation and use of other side panels 107.

[0040] Furthermore, the weather-resistant air source heat pump water heater also includes a distributor, which comprises a connecting roller 108, a guide plate 110, and several filter plates 111. The connecting roller 108 is connected to the bottom of the top plate 104 via a connecting rod 109. One end of the guide plate 110 is rotatably connected to the connecting roller 108, and the filter plates 111 are evenly distributed on the guide plate 110. The top plate 104 has a liquid inlet located above the guide plate 110. After entering through the liquid inlet, the liquid first falls onto the guide plate 110. Because the filter plates 111 are evenly distributed on the guide plate 110, the liquid will be filtered by the filter plates 111 during its flow, effectively removing impurities from the liquid and ensuring the water quality entering the storage tank. When the liquid flows through the guide plate 110, the guide plate 110 will rotate at a certain angle according to the flow rate and impact force of the liquid, allowing the liquid to be more evenly distributed into the storage tank, avoiding concentrated liquid impact on a certain point, and reducing damage to the internal structure of the storage tank.

[0041] Furthermore, the guide plate 110 is provided with a pull rope 112, one end of which extends out from the box 101. The pull rope 112 can pull the guide plate 110 to flip to an upward position. The bottom plate 102 is provided with a drain port 113. The top plate 104 is provided with a guide tube 106, which is provided with a movable block 117 and a turntable 114. One end of the pull rope 112 is fixed to the movable block 117, and the turntable 114 is rotatably connected to the movable block 117. The turntable 114 is provided with a protrusion 1141, and the side wall of the guide tube 106 is provided with a slot 1061 for the protrusion 1141 to move.

[0042] When the filter plate 111 on the separator needs cleaning, the operator can pull the pull rope 112. The pull rope 112 moves the movable block 117 on the guide tube 106. Since the turntable 114 is rotatably connected to the movable block 117, and the protrusion 1141 on the turntable 114 moves within the slot 1061 on the side wall of the guide tube 106, the stability and directionality of the pull rope 112 are ensured. After the turntable 114 moves to the top of the guide tube 106, the turntable 114 is rotated so that the protrusion 1141 is misaligned with the slot 1061, fixing the movable block 117 to the top of the guide tube 106. As the pull rope 112 is pulled, the guide plate 110 rotates around the connecting roller 108 to an upward position. At this time, the impurities intercepted on the filter plate 111 will slide down to the drain port 113 on the bottom plate 102 due to gravity. At the same time, clean water is injected into the inlet 105. The clean water impacts the filter plate 111 in the opposite direction, washing away the impurities on the filter plate. The operator can discharge the impurities into the water tank through the drain port 113, thereby cleaning the separator and ensuring the filtration effect of the separator and the water quality in the water tank.

[0043] A filter screen is installed inside the inlet 105. This filter screen further filters the liquid entering the water storage tank, preventing larger particles of impurities from entering and reducing the filtration burden on the separator filter plate 111. The filter screen is detachable for easy regular cleaning or replacement to ensure its filtration performance. When installing the filter screen, it is securely fixed inside the inlet 105 using a specific slot or snap-fit ​​structure to prevent the filter screen from shifting or falling off under the impact of water flow.

[0044] In addition to its anti-corrosion and anti-aging properties, the weather-resistant powder coating on the outer drum also has excellent UV resistance. It will not fade or chalk under prolonged exposure to sunlight, maintaining the drum's aesthetic appearance. Furthermore, this powder coating has a certain degree of self-cleaning ability; the surface is not easily stained by dust and dirt, and even if a small amount of dirt adheres, it can be cleaned by rainwater.
