[0003] However, existing air source heat pump water heaters have structural design flaws in their water tanks, resulting in uneven water mixing in different areas of the tank and significant temperature differences between these areas. This leads to high energy consumption for heating, which is detrimental to energy conservation and environmental protection.

[0034] Please refer to Figures 1 to 2 The present invention provides a high-efficiency mixing tank, comprising: a tank body 1, a main heating device 2, and multiple guide plates 3.

[0035] Specifically, multiple guide plates 3 are spaced apart inside the housing 1 along a preset direction, and one of the adjacent guide plates 3 is connected to one side of the inner wall of the housing 1, and the other is connected to the other side of the inner wall of the housing 1, so that a flow channel 4 for liquid flow is formed inside the housing 1.

[0036] The housing 1 has an inlet 5 and an outlet 6. The inlet 5 is connected to one end of the flow channel 4, and the outlet 6 is connected to the other end of the flow channel 4. The main heating device 2 is located on the housing 1 near the inlet 5.

[0037] In this invention, multiple guide plates 3 are spaced apart inside the housing 1, forming a flow channel 4 inside the housing 1. Water entering through the inlet 5 can move rapidly along the flow channel 4 to the outlet 6 under the guidance of the guide plates 3, thereby ensuring uniform mixing of hot and cold water in different areas of the housing 1, reducing the temperature difference between different areas of the housing 1, achieving high mixing efficiency, and reducing heating energy consumption. The main heating device 2 is located on the housing 1 near the inlet 5, ensuring optimal heating effect and higher water temperature at the inlet 5. Cold water entering through the inlet 5 can mix with the hot water at this location, lowering the water temperature and balancing the water temperature in different areas of the housing 1, further reducing the temperature difference between different areas of the housing 1.

[0038] For example, please refer to Figure 1 The preset direction can be vertical, and multiple guide plates 3 can be arranged at intervals along the vertical direction in the housing 1. The side walls of the guide plates 3 are connected to the inner wall of the housing 1, so that the guide plates 3 are in a horizontal state. The projections of adjacent guide plates 3 in the vertical direction are staggered, thus forming a bow-shaped bend in the flow channel 4. The inlet 5 can be set at the lower part of the housing 1, and the outlet 6 can be set at the upper part of the housing 1, so that the flow direction of the flow channel 4 is in the direction of the arrow in the figure.

[0039] In other cases, the preset direction can also be horizontal or other directions. When the preset direction is horizontal, the guide vane 3 is in a vertical state.

[0040] Optionally, the number of guide vanes 3 and the spacing between adjacent guide vanes 3 can be adapted to the actual situation, and this utility model does not impose specific limitations in this regard. The side wall of the guide vane 3 and the inner wall of the housing 1 can be fixedly connected or detachably connected, such as by plug-in or bayonet connection, so as to facilitate the disassembly, replacement and maintenance of the guide vane 3.

[0041] For example, the main heating device 2 can be a microchannel heat exchanger. The heat exchange tubes of the microchannel heat exchanger can be installed inside the housing 1 near the water inlet 5, for example, at the bottom of the housing 1, to heat the water near the water inlet 5. In some cases, the heat exchange tubes of the microchannel heat exchanger can also be arranged around the outside of the housing 1 near the water inlet 5, which, while providing heating, can effectively prevent the heat transfer medium from entering the housing 1 and mixing with the water, thus affecting the water quality, in the event of a leak in the heat exchange tubes.

[0042] In one specific embodiment, please refer to Figure 2The guide plate 3 has multiple through holes 31 extending in a preset direction. Understandably, by opening through holes 31 on the guide plate 3, this embodiment can reduce the resistance of the guide plate 3 to the water flow inside the tank 1 without affecting the guiding function of the guide plate 3. This allows the water in the tank 1 to move not only along the flow channel 4, but also through the through holes 31 between different areas, further improving the mixing uniformity and mixing efficiency of hot and cold water in different areas, and making the water temperature in different areas closer.

[0043] Optionally, the multiple through holes 31 can be evenly distributed on the guide plate 3 or non-uniformly distributed on the guide plate 3. Preferably, the multiple through holes 31 are non-uniformly distributed on the guide plate 3. The non-uniformly distributed through holes 31 can make the water flow form a more complex flow pattern when passing through the guide plate 3, including the convergence of water flows in different directions, eddies, etc. This complex water flow characteristic is more conducive to the uniform mixing of water.

[0044] In one specific embodiment, the projection of the guide plate 3 on the housing 1 along a preset direction is located inside the housing 1 and covers 50% to 80% of the housing 1.

[0045] Taking the preset direction as the vertical direction as an example, please refer to... Figure 1 and Figure 2 In this example, the tank 1 can be a cylindrical water tank, and its vertical projection is circular. The vertical projection of the baffle 3 can be fan-shaped, and this fan-shaped projection is located within the circular projection of the tank 1. The projection of the side wall of the baffle 3 connected to the tank 1 is an arc, and the curvature of this arc matches the curvature of the circular projection. The projection of the other side wall of the baffle 3 is also an arc.

[0046] The projection of the baffle 3 onto the housing 1 in the vertical direction covers 50% to 80% of the housing 1, that is, the ratio of the area of ​​the fan-shaped projection of the baffle 3 to the area of ​​the circular projection of the housing 1 is 50% to 80%. The larger this ratio is, the larger the cross-sectional space occupied by the baffle 3 within the housing 1.

[0047] In this embodiment, the aforementioned ratio can be adaptively set according to the flow guidance requirements. Specifically, when the cross-sectional space occupied by the guide plate 3 is larger, the path of the flow channel 4 is more defined, and the constraint effect on the water flow is more obvious, causing the water flow to flow along the path defined by the guide plate 3. This allows for more precise guidance of the water flow from the inlet 5 to the outlet 6 of the water tank, improving the orderliness of the water flow and promoting thorough mixing of water in different areas. However, when the guide plate 3 occupies a large cross-sectional space, it also increases the resistance to the water flow. Conversely, when the cross-sectional space occupied by the guide plate 3 is small, the obstruction effect of the guide plate 3 on the water flow is relatively small, but at this time, the constraint ability of the guide plate 3 on the water flow is weak, making it difficult to accurately guide the direction of the water flow. This may result in more sideflows within the water tank, preventing the formation of a regular flow path. Therefore, the specific ratio can be adaptively set according to the flow guidance requirements, and this embodiment does not impose a specific limitation on it.

[0048] For example, in practical applications, the projection of the baffle 3 onto the housing 1 along a preset direction can cover 65% of the housing 1.

[0049] In one specific embodiment, the high-efficiency mixing tank also includes an auxiliary heating device 7, which is disposed on the tank body 1, and the heating end 71 of the auxiliary heating device 7 is located in a preset area 41 in the flow channel 4, which is between the inlet 5 and the outlet 6.

[0050] In practical applications, the main heating device 2 serves as the primary heating equipment, undertaking the heating task independently under normal operating conditions. However, under special conditions such as low temperatures, the auxiliary heating device 7 can work together with the main heating device 2 to meet the need for rapid heating in low-temperature conditions, resulting in a good user experience. Furthermore, based on the dual heating mechanism of the main heating device 2 and the auxiliary heating device 7, if one of them fails, the other can still complete the heating work, thus improving the reliability of the device.

[0051] For example, please refer to Figure 1 In embodiments where the preset direction is vertical, the auxiliary heating device 7 can be located in the lower middle part of the housing 1. Preferably, the auxiliary heating device 7 is spaced apart from the water inlet 5 by a guide plate 3, so that the preset area 41 where the heating end 71 of the auxiliary heating device 7 is located is downstream of the main heating device 2 in the flow channel 4. Under special low-temperature conditions, when the water heated by the main heating device 2 flows along the flow channel 4, it can be reheated by the auxiliary heating device 7 downstream, which can effectively improve the rapid heating effect.

[0052] For example, the auxiliary heating device 7 can be an electric heating tube, and the heating end 71 of the auxiliary heating device 7 is the pipeline part of the electric heating tube. An electric heating port 8 can also be provided on the housing 1, and the connection end 72 of the electric heating tube can be connected to an external power supply device through the electric heating port 8.

[0053] In one specific embodiment, the inner wall of the housing 1 may be provided with physical corrosion protection components and electronic corrosion protection components. The electronic corrosion protection components are electrically connected to an external power supply device.

[0054] In this embodiment, based on the setting of physical and electronic anti-corrosion components, dual protection of ordinary anti-rust and descaling and electronic anti-rust and descaling is achieved, which can effectively improve the water quality in tank 1 and extend the service life of tank 1.

[0055] For example, please refer to Figure 1 The physical corrosion protection component may include a physical magnesium rod 9, and the electronic corrosion protection component may include an electronic magnesium rod 10 electrically connected to an external power supply device. The electronic magnesium rod 10 may be disposed on the top of the housing 1, and the physical magnesium rod 9 may be disposed in the middle area of ​​the housing 1.

[0056] In some cases, magnesium rods can be replaced with other metal corrosion-resistant parts such as aluminum rods and zinc rods.

[0057] For example, a magnesium rod mounting port 11 may be provided at the top and middle of the enclosure 1. An electronic magnesium rod 10 may be inserted into the enclosure 1 through the magnesium rod mounting port 11 at the top, and a physical magnesium rod 9 may be inserted into the enclosure 1 through the magnesium rod mounting port 11 at the middle. The end of the electronic magnesium rod 10 facing away from the interior of the enclosure 1 may be electrically connected to an external power supply device through the magnesium rod mounting port 11.

[0058] In one specific embodiment, the inner wall of the enclosure 1 is further provided with an enamel anti-corrosion layer 12 to further achieve rust and corrosion prevention of the enclosure 1. In other embodiments, the enamel anti-corrosion layer 12 can be replaced with other material layers with anti-corrosion properties, such as epoxy resin layer, zinc plating layer, etc.

[0059] In one specific embodiment, a first temperature measuring port 13 is provided on the housing 1 near the water inlet 5, and a second temperature measuring port 14 is provided on the housing 1 near the water outlet 6.

[0060] In practical applications, external temperature sensors can enter the interior of the tank 1 through the first temperature measuring port 13 and the second temperature measuring port 14 to detect water temperature. Understandably, the second temperature measuring port 14 is close to the water outlet 6, so the temperature sensor entering through the second temperature measuring port 14 can accurately detect the water temperature output to the user. The first temperature measuring port 13 is close to the water inlet 5, so the temperature sensor entering through the first temperature measuring port 13 can detect the water temperature at the bottom of the tank 1, thereby determining whether the main heating device 2 and the auxiliary heating device 7 need to be turned on or off.

[0061] Preferably, in some cases, a temperature sensor 15 is preset in the housing 1 at the position corresponding to the first temperature measuring port 13 and the second temperature measuring port 14. The temperature sensor 15 can be connected to an external device via the first temperature measuring port 13 or the second temperature measuring port 14 to send the detected water temperature to the outside.

[0062] In one specific embodiment, a drain port 16 is provided at the bottom of the housing 1, and a drain valve is installed in the drain port 16. The drain valve facilitates the user in discharging sewage and impurities from the housing 1, resulting in a better user experience.

[0063] Furthermore, a PT valve port 17 can be installed on the housing 1, and a PT valve 18 can be installed in the PT valve port 17. The PT valve 18 is a temperature and pressure safety valve, which has both overpressure protection and overtemperature protection functions. When the pressure or temperature inside the housing 1 exceeds the preset safety value, the PT valve 18 will automatically open, releasing some water to reduce the pressure or temperature, thereby protecting the housing 1 from damage. With the PT valve 18 installed on the housing 1, a temperature sensor and a pressure sensor connected to the PT valve 18 can also be installed inside the housing 1 to determine the temperature and pressure inside the housing 1, thereby cooperating with the PT valve 18 to achieve overpressure protection and overtemperature protection.

[0064] This utility model also provides a water heater, including the high-efficiency mixing tank described in any of the above embodiments.

[0065] In one specific embodiment, please refer to Figure 3 and Figure 4 The water heater may also include a housing 19 and an electrical control system 20 disposed within the housing 19. Specifically, the casing 1 is disposed within the housing 19, and the housing 19 has multiple openings 21, which correspond to the water inlet 5, water outlet 6, drain outlet 16, PT valve port 17, magnesium rod mounting port 11, second temperature measuring port 14, and auxiliary heating device 7 of the casing 1, respectively. The electrical control system 20 is connected to the main heating device 2, the auxiliary heating device 7, and the electronic magnesium rod 10, respectively, to control the main heating device 2 and the auxiliary heating device 7 to start or stop working, and to provide electrical energy to the electronic magnesium rod 10.

[0066] With temperature sensors 15 pre-installed at the positions corresponding to the first temperature measuring port 13 and the second temperature measuring port 14 inside the housing 1, the electronic control system 20 is also connected to the temperature sensors 15 to detect the water temperature at the water inlet 5 and the water outlet 6 inside the housing based on the temperature sensors 15, thereby obtaining the water temperature output to the user, and controlling the main heating device 2 and the auxiliary heating device 7 to start or stop working according to the water temperature inside the housing 1.

[0067] When the main heating device 2 is a microchannel heat exchanger, the water heater may further include a compressor 22, an evaporator 23, and a fan (not shown) for supplying air to the evaporator 23, all housed in the casing 19. Specifically, the electrical control system 20 is connected to the compressor 22 and the fan, respectively. The output end of the compressor 22, the evaporator 23, and the input end of the microchannel heat exchanger are sequentially connected, with the output end of the microchannel heat exchanger connected to the input end of the compressor 22. The fan is used to supply air to the evaporator 23. Thus, this embodiment provides an air source heat pump water heater.

[0068] In summary, this utility model provides a high-efficiency mixing tank and water heater. The high-efficiency mixing tank is based on multiple guide plates spaced apart inside the tank body, which forms a flow channel inside the tank body. Water input from the inlet can move quickly along the flow channel to the outlet under the guidance of the guide plates, thereby enabling uniform mixing of hot and cold water in different areas of the tank body, reducing the water temperature difference between different areas of the tank body, resulting in high mixing efficiency and reduced heating energy consumption.

[0069] The main heating device is located on the tank body near the water inlet, which ensures the best heating effect and higher water temperature at the water inlet. The cold water input from the water inlet can mix with the hot water here to lower the water temperature, thereby balancing the water temperature in different areas of the tank and further reducing the water temperature difference between different areas of the tank.
