[0039] The water purifier 100 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0040] Referring to Figures 1 - 3 As shown, the water purifier 100 according to an embodiment of the present utility model may include: a housing 10, a mounting frame 20 and a filtration assembly.

[0041] Specifically, the housing 10 has a receiving cavity 101. The mounting frame 20 is installed in the receiving cavity 101 and is connected to the housing 10. The filtration assembly is installed on the mounting frame 20. Among them, the receiving cavity 101 includes at least one installation area, and the installation area is located on one side of the mounting frame 20 and is used for installing different functional components so that the water purifier 100 has different functions.

[0042] The filtration assembly can be used for water filtration to remove harmful substances in the water to obtain domestic water, drinking water, etc. The filtration assembly may include primary filtration or multi-stage filtration. For example, in some embodiments, the filtration assembly includes pre-filtration, RO reverse osmosis filtration and post-filtration to achieve three-stage filtration to obtain directly drinkable drinking water; in some embodiments, the filtration assembly includes pre-filtration and post-filtration to achieve two-stage filtration to obtain domestic water.

[0043] The mounting frame 20 can realize the installation and positioning of the filtration assembly in the receiving cavity 101, and facilitate the disassembly, assembly and replacement of the filtration assembly. In some specific embodiments, the mounting frame 20 may be provided with jacks, and the filtration assembly includes at least one filter element, and the filter element is detachably inserted into the jacks, which is convenient for the disassembly and assembly of the filter element and for the filter element to be butt-connected and communicated with a water circuit structure such as a water circuit board assembly 80.

[0044] The installation area refers to the space in the receiving cavity 101 for installing functional components. The functional components refer to components that can achieve specific functions, such as a heating assembly 50 for realizing a heating function, a gas-liquid treatment assembly 40 for realizing a sparkling water function, a fixed-frequency pump 61 for realizing fixed-flow liquid pumping, a variable-frequency pump 63 for realizing adjustable-flow liquid pumping, etc.

[0045] The installation area for installing different functional components means that for water purifiers 100 of different specifications, different functional components can be installed in the same installation area. For example, a heating component 50 is installed in a certain installation area of a water purifier 100 of one specification, and a gas-liquid treatment component 40 is installed in this installation area of a water purifier 100 of another specification, so that the two specifications of water purifiers 100 have different functions respectively. However, except for the functional components in this installation area, the installation positions and structures of other components of the water purifier 100 can be exactly the same.

[0046] Therefore, other components of the water purifier 100 have strong versatility, and there are many universal components in water purifiers 100 of different specifications. There is no need to adjust the layout and structure of the universal components, which is beneficial to reducing the mold development cost of other components and the overall structural layout design cost of the water purifier 100. Moreover, each functional component of the water purifier 100 is modular, and function replacement is easier.

[0047] According to the water purifier 100 of the embodiment of the present invention, the same installation area of different water purifiers 100 can be used to install different functional components, so that different water purifiers 100 have different functions, increasing the variety diversity of the water purifiers 100, and improving the versatility of the components of the water purifiers 100, which is beneficial to reducing the mold development cost and the overall machine layout design cost during the production process, and greatly reducing the production cost.

[0048] In some embodiments, as Figure 1 and Figure 2 shown, the installation area includes a first installation area 102. The first installation area 102 is used to install a gas-liquid treatment component 40 or a heating component 50. The gas-liquid treatment component 40 is used to generate bubble water, and the heating component 50 is used to heat water.

[0049] Among them, for the water purifier 100 with a gas-liquid treatment component 40 installed in the first installation area 102, the water purifier 100 can output bubble water to realize the bubble water function. The bubble water has microbubbles and can be used to remove agricultural residues on fruits and vegetables to meet the user's fruit and vegetable cleaning needs. In some specific embodiments, the gas-liquid treatment component 40 can also be used to produce microbubble cleaning water for self-cleaning the flow path in the water purifier 100, such as cleaning the filter component to improve the service life of the filter component.

[0050] For the water purifier 100 with a heating component 50 installed in the first installation area 102, the water purifier 100 can output hot water, for example, output hot water at a fixed temperature or output hot water at different temperatures according to the user's setting to realize the hot water function.

[0051] In some specific embodiments, the heating component 50 can be an instant heater; or the heating component 50 can be a hot water tank 52 with a heater inside. The hot water tank 52 can not only heat water but also store the heated water, making the hot water supply of the water purifier 100 more stable. Or, the heating component 50 can include a hot water tank 52 and a heater 53 connected in series with the hot water tank 52. The water heated by the heater 53 can be stored in the hot water tank 52, directly output to the water outlet, or the temperature of the water output from the hot water tank 52 can be heated to meet the water temperature requirement, etc.

[0052] In the above embodiments, both the gas-liquid treatment component 40 and the heating component 50 can be installed in the first installation area 102, enabling the water purifier 100 to obtain a water purifier 100 with a bubble water function and a water purifier 100 with a hot water function by replacing the functional components installed in the first installation area 102, without being affected by the installation and structure of the components in other areas of the water purifier 100.

[0053] In some embodiments, as Figure 2 and Figure 3 shown, the installation area includes a second installation area 103. The second installation area 103 is used to install a fixed-frequency pump 61 and a power adapter 62. The power adapter 62 is connected to the fixed-frequency pump 61 and used to supply power to the fixed-frequency pump 61. Or the second installation area 103 is used to install a variable-frequency pump 63 and a variable-frequency power supply 64. The variable-frequency power supply 64 is connected to the variable-frequency pump 63 and used to supply power to the variable-frequency pump 63.

[0054] The fixed-frequency pump 61 can drive the water flow at a fixed speed and works stably. The variable-frequency pump 63 can adjust the speed to regulate the flow rate, and the control is more flexible and variable. The power adapter 62 can provide adapted electric energy to the fixed-frequency pump 61, and the variable-frequency power supply 64 can provide adapted electric energy to the variable-frequency pump 63, enabling the fixed-frequency pump 61 and the variable-frequency pump 63 to work properly.

[0055] In the above, both the fixed-frequency pump 61 and the variable-frequency pump 63 can be installed in the first installation area 102, enabling the water purifier 100 to obtain a water purifier 100 with a constant flow rate or an adjustable flow rate by replacing the water pumps (i.e., the fixed-frequency pump 61 and the variable-frequency pump 63) and the corresponding power supply components (i.e., the power adapter 62 and the variable-frequency power supply 64) installed in the second installation area 103, without being affected by the installation and structure of the components in other areas of the water purifier 100.

[0056] In some embodiments of the present invention, as Figure 1 and Figure 4As shown, the gas-liquid treatment assembly 40 includes a first mounting base 41, an ejector 42, a gas-liquid mixer 43, and a bubbler 44. The first mounting base 41 is connected to at least one of the housing 10 and the mounting frame 20, and the ejector 42, the gas-liquid mixer 43, and the bubbler 44 are mounted on the first mounting base 41.

[0057] The ejector 42 is used to preliminarily mix water and gas. The gas-liquid mixer 43 can achieve sufficient mixing of water and gas to obtain a gas-liquid mixture, and the bubbler 44 can process the gas-liquid mixture to obtain bubble water with microbubbles.

[0058] The ejector 42, the gas-liquid mixer 43, and the bubbler 44 being mounted on the first mounting base 41 can integrate the gas-liquid treatment assembly 40, and there is no need for the ejector 42, the gas-liquid mixer 43, and the bubbler 44 to be separately connected to structures such as the housing 10 and the mounting frame 20, which is beneficial to simplifying the structures of the housing 10 and the mounting frame 20 and facilitating the reduction of processing difficulty. And the integrated gas-liquid treatment assembly 40 according to actual needs can be integrally mounted in the first mounting area 102, and the assembly of the gas-liquid treatment assembly 40 can be carried out outside the housing 10, which is beneficial to improving the assembly efficiency.

[0059] The first mounting base 41 can be connected only to the housing 10, or only to the mounting frame 20, or simultaneously to both the housing 10 and the mounting frame 20, as long as the installation of the first mounting base 41 in the first mounting area 102 can be achieved.

[0060] In some embodiments, continue to refer to Figure 1 As shown, at least a part of the mounting frame 20 is located above the first mounting base 41. The mounting frame 20 is provided with a first connecting portion 201, and the base 11 of the housing 10 is provided with a second connecting portion 111. The upper part of the first mounting base 41 is connected to the first connecting portion 201, and the lower part of the first mounting base 41 is connected to the second connecting portion 111.

[0061] The first connecting portion 201 and the second connecting portion 111 can install and fix the first mounting base 41 by the upper and lower parts of the first mounting base 41, improving the installation stability of the first mounting base 41.

[0062] Among them, the connection method between the first connecting portion 201 and the first mounting base 41 can be, but is not limited to, fastener connection, snap connection, plug connection, etc.; the connection method between the second connecting portion 111 and the first mounting base 41 can be, but is not limited to, fastener connection, snap connection, plug connection, etc.

[0063] In some specific embodiments, the fastener is horizontally disposed through the first mounting seat 41 and the first connecting portion 201 to connect the first mounting seat 41 and the first connecting portion 201; the fastener is vertically disposed through the second connecting portion 111 and the first mounting seat 41 to connect the first mounting seat 41 and the housing 10.

[0064] The penetrating directions of the fasteners corresponding to the first connecting portion 201 and the second connecting portion 111 are different, which can provide fastening force for the first mounting seat 41 from different directions, improve the stability of the first mounting seat 41, and reduce the vibration of the first mounting seat 41 and the components on the first mounting seat 41 during operation.

[0065] In addition, the fastener corresponding to the first connecting portion 201 is located above the first mounting seat 41, and the horizontal installation can reduce the interference of other components on the installation of the fastener. For example, only the side plate of the housing 10 needs to be disassembled to disassemble and assemble the fastener; the fastener corresponding to the second connecting portion 111 is located below the first mounting seat 41, and the vertical installation can be performed from bottom to top outside the housing 10 without interference from other components.

[0066] In some embodiments of the present utility model, as Figure 2 and Figure 5 shown, the heating assembly 50 includes a second mounting seat 51, a hot water tank 52, and a heater 53. The second mounting seat 51 is connected to at least one of the housing 10 and the mounting frame 20. The hot water tank 52 is mounted on the second mounting seat 51, and the heater 53 is connected to the hot water tank 52 through a pipeline. In some embodiments, the heating assembly 50 may further include a water pump 54, and the water pump 54 is connected to the hot water tank 52 through a pipeline and is used to drive the water stored in the hot water tank 52 to flow out.

[0067] The hot water tank 52 is used to store hot water, and the heater 53 is used to heat the water. The water can flow into the hot water tank 52 for storage after being heated by the heater 53, or the water can directly enter the heater 53 for heating. Or, the warm water stored in the hot water tank 52 can flow out of the hot water tank 52, flow through the heater 53, and be heated to a higher temperature by the heater 53.

[0068] The second mounting seat 51 can be only connected to the housing 10, or only connected to the mounting frame 20, or simultaneously connected to the housing 10 and the mounting frame 20, as long as the installation of the second mounting seat 51 in the first installation area 102 can be realized.

[0069] It should be noted that, on the housing 10 and the mounting frame 20, the structures for connecting to the first mounting seat 41 and the structures for connecting to the second mounting seat 51 can be the same to simplify the structures of the housing 10 and the mounting frame 20, or can be different to meet the differences in components and center of gravity positions of the gas-liquid treatment assembly 40 and the heating assembly 50, etc., and specifically improve the fixing stability of different functional components.

[0070] In some embodiments, as Figure 2 shown, the second mounting seat 51 is connected to the base 11 of the housing 10 through fasteners, the lower part of the hot water tank 52 is mounted on the second mounting seat 51, and the upper part of the hot water tank 52 is connected to the mounting frame 20 through fasteners.

[0071] The hot water tank 52 stores water and has a relatively large weight. By fixing the upper and lower parts of the hot water tank 52 respectively, the stability of the hot water tank 52 can be improved.

[0072] In some specific embodiments, the second mounting seat 51 can be connected to the first connecting portion 201 on the base 11, that is, the first connecting portion 201 can be used for mounting both the first mounting seat 41 and the second mounting seat 51; the mounting frame 20 can be provided with a third connecting portion 202, the third connecting portion 202 is connected to the upper part of the hot water tank 52, and the third connecting portion 202 and the second connecting portion 111 are of different structures to meet the different connection points caused by the structural differences between the upper parts of the hot water tank 52 and the first mounting seat 41.

[0073] According to some embodiments of the present invention, as Figures 1 - 3 shown, the first mounting area 102 and the second mounting area 103 are arranged along the first horizontal direction F1. Here, the first horizontal direction F1 can be but is not limited to the length direction of the housing 10 (such as Figure 1 the front-back direction shown).

[0074] Both the gas-liquid treatment assembly 40 and the heating assembly 50 installed in the first mounting area 102 need to be connected to water. Therefore, there is a risk of liquid leakage in the gas-liquid treatment assembly 40 and the heating assembly 50; the fixed-frequency pump 61, the power adapter 62, the variable-frequency pump 63, the variable-frequency power supply 64, etc. installed in the second mounting area 103 all need to be powered on. Therefore, if water enters, there is a risk of short circuit and burnout.

[0075] In the above embodiments, by arranging the first mounting area 102 and the second mounting area 103 along the first horizontal direction F1, the separation of water and electricity in the horizontal direction can be achieved. Even if the gas-liquid treatment assembly 40 and the heating assembly 50 have liquid leakage, the liquid will flow downward to the base 11 of the housing 10 and is not likely to flow horizontally to the second mounting area 103, effectively reducing the risk of water ingress into the powered functional components.

[0076] In some embodiments, asFigure 1 and Figure 2 As shown in Figure 2 , the fixed-frequency pump 61 and the power adapter 62 are arranged along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction F1. The fixed-frequency pump 61 has a relatively large length and occupies a relatively large space in the first horizontal direction F1. By arranging the power adapter 62 and the fixed-frequency pump 61 along the second horizontal direction, the overall occupied space of the second installation area 103 in the first horizontal direction F1 can be reduced, the structure is more compact, and the layout is more reasonable.

[0077] In some embodiments, as Figure 3 shown in Figure 3 , the variable-frequency pump 63 and the variable-frequency power supply 64 are arranged along the first horizontal direction F1. The variable-frequency pump 63 has a relatively small length and occupies a relatively small space in the first horizontal direction F1. By arranging the variable-frequency power supply 64 and the variable-frequency pump 63 along the first horizontal direction F1, the space in the first horizontal direction F1 can be fully utilized, making the layout more reasonable.

[0078] According to some embodiments of the present invention, as Figures 1 - 3 shown in Figures 1 - 3 , the mounting frame 20 includes a connected first frame body 21 and a second frame body 22. The first frame body 21 is located above the second frame body 22, and the filtering component is installed on the first frame body 21.

[0079] In some embodiments, as Figure 1 and Figure 2 shown in Figure 1 and Figure 2 , the fixed-frequency pump 61 is installed on the second frame body 22. The water purifier 100 further includes a first mounting bracket 71. The first mounting bracket 71 is located on one side of the second frame body 22 along the second horizontal direction and is connected to the first frame body 21. The power adapter 62 is installed on the side of the first mounting bracket 71 facing away from the fixed-frequency pump 61.

[0080] The fixed-frequency pump 61 is installed on the second frame body 22, and there is no need to be directly connected to the machine shell 10, which can simplify the structure of the machine shell 10, reduce the production difficulty, and is beneficial to reducing the number of openings in the machine shell 10 and improving the appearance integrity. The connection method between the fixed-frequency pump 61 and the second frame body 22 includes but is not limited to fastening connection, snap connection, etc.

[0081] The fixed-frequency pump 61 is used to pump liquid. During the working process, it needs to be connected to the water circuit. Inevitably, there is some liquid in the fixed-frequency pump 61, and heat is generated during the working process of the fixed-frequency pump 61. By setting the first mounting bracket 71 to separate the fixed-frequency pump 61 from the power adapter 62, on the premise of realizing the installation of the power adapter 62 and its electrical connection with the fixed-frequency pump 61, not only can the risk of water ingress into the power adapter 62 caused by leakage of the fixed-frequency pump 61 be reduced, but also a heat insulation effect can be achieved, reducing the transfer of heat from the fixed-frequency pump 61 to the power adapter 62, and the temperature of the power adapter 62 is not likely to be too high to affect its service life.

[0082] In some specific embodiments, the second housing 22 defines a cavity which is open on one side along the second horizontal direction. The fixed-frequency pump 61 is installed in the cavity, and the first mounting bracket 71 is provided at the open mouth of the cavity. The power adapter 62 is installed on the side of the first mounting bracket 71 facing away from the cavity and is disassembled and assembled through the second mounting bracket 72, facilitating the installation of the fixed-frequency pump 61 in the cavity.

[0083] In some embodiments, as Figure 3 shown, the variable-frequency pump 63 is installed on the second housing 22. The upper end of the variable-frequency power supply 64 is connected to the first housing 21 and the lower end is connected to the second housing 22. Both the variable-frequency pump 63 and the variable-frequency power supply 64 are installed and fixed through the second housing 22, which is beneficial to reducing the number of components. For example, in some embodiments where the second housing 22 defines a cavity, the lower end of the variable-frequency power supply 64 can be connected to the bottom wall of the cavity.

[0084] It should be noted that in the embodiments of the present application, the mounting frame 20 can simultaneously have a structure for mounting the fixed-frequency pump 61 and the power adapter 62 and a structure for mounting the variable-frequency pump 63 and the variable-frequency power supply 64, making the mounting frame 20 more versatile and reducing the development cost.

[0085] In some embodiments of the present utility model, as Figures 1 - 3 shown, the water purifier 100 further includes a second mounting bracket 72 and a control board assembly 70. The second mounting bracket 72 is connected to the lower part of the mounting frame 20. For example, the second mounting bracket 72 can be connected to the lower end of the first housing 21.

[0086] The control board assembly 70 can be used to control the working state of the water purifier 100, or can be used to control the working state of some functional components in the water purifier 100. For example, in some embodiments including the heating assembly 50, as Figure 2 and Figure 3 shown, the control board assembly 70 can be communicatively connected to the heating assembly 50 to control the start and stop of heating, the heating temperature, the heating time, etc. of the heating assembly 50. The working states of other functional components such as the valve body and the water pump of the water purifier 100 can be controlled through components such as the display assembly; in some embodiments including the gas-liquid treatment assembly 40, the control board assembly 70 can be used to control the working state of the water purifier 100, and the display assembly may not be provided, or the display assembly is connected to the control board assembly 70 so that the control board assembly 70 can interact with the user through the display assembly.

[0087] In addition, the second mounting bracket 72 is located on one side of the fixed-frequency pump 61 or the variable-frequency pump 63 along the second horizontal direction, that is, in some embodiments where the second housing 22 defines a cavity, the second mounting bracket 72 is located on one side of the cavity along the second horizontal direction. Among them, the first mounting bracket 71 can also be two separately provided brackets, or can be a bracket connected as a whole.

[0088] The control board assembly 70 is mounted on the side of the second mounting bracket 72 facing away from the fixed-frequency pump 61 or the variable-frequency pump 63. By providing the second mounting bracket 72 to separate the water pump from the control board assembly 70, on the premise of realizing the installation of the control board assembly 70 and its electrical connection with the fixed-frequency pump 61, not only can the risk of water ingress into the control board assembly 70 caused by water pump leakage be reduced, but also a heat insulation effect can be achieved, reducing the transfer of the water pump heat to the control board assembly 70, and the temperature of the control board assembly 70 is not likely to be too high and damaged.

[0089] According to some embodiments of the present invention, as Figures 1 - 3 shown, a water circuit board assembly 80 is further provided in the accommodation cavity 101. The water circuit board assembly 80 is located above the first installation area 102, and the filter assembly is located above the second installation area 103 and is arranged with the water circuit board assembly 80 along the first horizontal direction F1.

[0090] The water circuit board assembly 80 integrates the liquid flow path of the water purifier 100, can realize the pipeline connection between various functional components of the water purifier 100, and the integrated arrangement of the water-passing pipelines can make the layout in the accommodation cavity 101 neater, and is conducive to making the liquid flow path orderly in the wet area and not easily extending to other areas such as the dry area. Of course, all the liquid flow paths of the water purifier 100 can be integrated in the water circuit board assembly 80, or can be partially integrated in the water circuit board assembly 80 according to needs, which are all conducive to improving the orderliness of the liquid flow path layout in the accommodation cavity 101.

[0091] Adopting the arrangement method of the above embodiments enables the gas-liquid treatment assembly 40 or the heating assembly 50 to be relatively close to the water circuit board assembly 80 for easy connection. Moreover, the gas-liquid treatment assembly 40 with relatively large vibration and the heating assembly 50 with relatively large weight can be located at the lower part of the water purifier 100 to reduce the center of gravity of the water purifier 100 and improve the overall stability of the machine. In addition, the filter assembly and the water circuit board assembly 80 have the same height or a small difference in the vertical direction, so as to facilitate the direct connection between the filter assembly and the water circuit board assembly 80. The connection part is located on the water circuit board assembly 80 and is staggered from the second installation area 103 in the first horizontal direction F1, reducing the risk of liquid leakage to the energized functional components such as the water pump, the power adapter 62, the variable-frequency power supply 64, and the control board assembly 70 due to the sealing failure of the connection part.

[0092] According to some specific embodiments of the present invention, as Figure 4 and Figure 5As shown, the filtration component includes a first filter element 31 and a second filter element 32. The first filter element 31 has a first filtration flow path 311 and a second filtration flow path 312. The water circuit board assembly 80 has a first water circuit 801 and a second water circuit 802. The inlet of the first water circuit 801 is in communication with the outlet of the first filtration flow path 311, and a heating component 50 or a gas-liquid treatment component 40 is connected in series to the first water circuit 801. The inlet of the second water circuit 802 is in communication with the outlet of the first filtration flow path 311, and the second filter element 32 and the second filtration flow path 312 are connected in series to the second water circuit 802.

[0093] Among them, in the embodiment where the heating component 50 is connected in series to the first water circuit 801, as Figure 5 shown, the heating component 50 can heat the water flowing through the first water circuit 801 so that the outlet of the first water circuit 801 can output hot water, realizing the hot water function.

[0094] The specific flow path is as follows: the water from the water source flows through the first filtration flow path 311 for pre-filtration, then flows through the heating component 50 for heating, and finally flows out from the hot water outlet of the first water circuit 801.

[0095] In the embodiment where the gas-liquid treatment component 40 is connected in series to the first water circuit 801, as Figure 4 shown, the gas-liquid treatment component 40 can generate bubble water so that the outlet of the first water circuit 801 can output bubble water, realizing the bubble water function. For example, the gas-liquid treatment component 40 may include a jet injector 42, a gas-liquid mixer 43, and a bubbler 44 arranged in sequence along the water flow direction.

[0096] The specific flow path is as follows: the water from the water source flows through the first filtration flow path 311 for pre-filtration, then flows to the jet injector 42, is preliminarily mixed with the gas flowing into the jet injector 42 from the gas source, and then flows into the gas-liquid mixer 43 for full mixing to obtain a gas-liquid mixture. The gas-liquid mixture is further processed by the bubbler 44 to obtain micro-bubble water, and finally the micro-bubble water can flow out from the bubble water outlet of the first water circuit 801.

[0097] The second water circuit 802 is connected in series with the second filter element 32 and the second filtration flow path 312, so that the water at the outlet of the second water circuit 802 undergoes three-stage filtration, specifically filtration by the first filtration flow path 311, filtration by the second filter element 32, and filtration by the second filtration flow path 312, to obtain pure water (or drinking water) that can be directly drunk. Here, the second filter element 32 can be provided on the upstream side or the downstream side of the second filtration flow path 312. In some specific embodiments, as Figure 4 and Figure 5 shown, the first filtration flow path 311 is for pre-filtration, the second filtration flow path 312 is for post-filtration, and the second filter element 32 is for RO reverse osmosis filtration and is connected in series between the first filtration flow path 311 and the second filtration flow path 312.

[0098] In the above embodiment, the water purifier 100 integrates multiple functions, which can meet more needs of users. In addition, the first filter element 31 integrates two-stage filtration, reducing the number of components and making the structure more compact.

[0099] Next, the water purifier 100 according to a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0101] The housing 10 has a receiving cavity 101, and the receiving cavity 101 is generally a rectangular parallelepiped space and has a dimension in the front-rear direction greater than the dimension in the left-right direction. The mounting frame 20 is provided at the front part of the receiving cavity 101 and includes a first frame body 21 and a second frame body 22. The first frame body 21 has insertion holes for inserting the first filter element 31 and the second filter element 32; the second frame body 22 is located below the first frame body 21 and in the second installation area 103.

The control board assembly 70 and the power adapter 62 are installed on the left side of this bracket, and the control board assembly 70 is used to control the working state of the fixed-frequency pump 61. The water circuit board assembly 80 is located at the rear side of the first frame body 21. The first installation area 102 is located at the rear side of the second frame body 22, and the gas-liquid treatment assembly 40 is installed in the first installation area 102.
