[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0043] In order to improve the drinking water quality and the richness of drinking water functions of users, existing water purifiers are not only equipped with water purification modules, but also with cooling water modules, instant heating modules, and even ice making modules.

[0044] The water in the cold water module is generally stored in a cold water tank. The water in the cold water tank will produce odor if it is not drunk for a long time. The cold water tank is located inside the water purifier body and it is not easy to pour out the cold water that has not been drunk for a long time. Therefore, a reflux system is provided to make the water in the cold water tank flow back to the water purification module for re-filtration to adjust the odor of the cold water in the cold water tank.

[0045] The reflux system requires additional structure to implement, and the space inside the water purifier is already very cramped, and the water purifier needs to meet the user's demand for small size so as not to occupy too much countertop space. It is very difficult to install the reflux system structure without increasing the space occupied by the water purifier.

[0046] In a typical water purifier application scenario, assume a multifunctional water purifier whose internal space has been tightly occupied by various functional modules. The cold water tank has a capacity of 5 liters, and the water purification module contains a multi-stage filter element installed at the bottom. To achieve the reflux function, it is necessary to install a reflux pump with a flow rate of 2 liters / minute in a limited space, and arrange a water pipe with a diameter of 8 mm to connect the water outlet of the cold water tank, the reflux pump and the water inlet of the water purification module. In addition, the power connection of the reflux pump and the layout of the control line need to be considered. In this compact structure, each additional component may lead to a readjustment of the overall layout and even affect the performance of other functional modules. For example, the vibration of the reflux pump may affect the efficiency of the refrigeration system, or the added water circuit may cause a spatial conflict with the heating element of the instant heating module.

[0047] If this technical problem cannot be effectively solved, it will lead to multiple serious technical consequences. First, the overall size of the water purifier may have to be increased, which will directly affect the market competitiveness of the product. Secondly, the tight internal space may lead to increased interference between the various functional modules, affecting the performance of core functions such as refrigeration, heating and purification. For example, the improper layout of the return system may lead to the complication of the water system and increase the risk of water pollution. In addition, heat accumulation in a compact space may affect the refrigeration efficiency and even shorten the service life of key components. In the long run, these problems may lead to reduced product reliability and increased maintenance difficulty, ultimately affecting user experience and product market performance. Therefore, without increasing the overall volume of the water purifier, the reasonable layout of the return system has become a key technical issue that needs to be solved urgently.

[0048] In view of this, the present invention proposes a water purifier 100 .

[0049] What needs to be explained about the orientation of the water purifier 100 is that the user generally faces the water purifier 100 to collect water when using the water purifier 100, and the function of the first water outlet 111 is to flow out purified water directly for the user to drink. Therefore, the side where the first water outlet 111 is provided (the side facing the user) is the front side of the water purifier 100, and the side to the left of the front side of the water purifier 100 is the left side of the water purifier 100, the side to the right of the front side of the water purifier 100 is the right side of the water purifier 100, and the side opposite to the front side of the water purifier 100 is the back side of the water purifier 100.

[0050] See also Figures 1 to 3 In one embodiment of the present invention, the water purifier 100 includes a body 1, a refrigeration module 2, an instant heating module 3, a water purification module 4 and a reflux pump 6. The body 1 forms an installation cavity 1a. The body 1 includes a body 11 and a base 12. The body 11 is installed on the base 12. The front side of the body 11 is provided with a first water outlet 111. The refrigeration module 2 includes a cold water tank 21, and the cold water tank 21 is installed in the installation cavity 1a. The instant heating module 3 is installed in the base 12. The front side of the cold water tank 21; the water purification module 4 includes a filter element assembly 41 and a boost pump 42, the filter element assembly 41 is installed on the base 12 through a mounting frame 5, and a mounting space 11a is formed on the lower side of the filter element assembly 41, and the boost pump 42 is installed on the base 12 and is located in the mounting space 11a; installed on the mounting frame 5, and the reflux pump 6 is adjacent to the filter element assembly 41, and the reflux pump 6 is used to draw cold water in the cold water tank 21 into the filter element assembly 41.

[0051] It should be noted that the body 11 is used to accommodate and install the internal structure of the body 11. In this embodiment, the raw water tank 10a is arranged outside the body 11, which can facilitate the user to add water to the raw water tank 10a, and also facilitate the replacement of waste water and cleaning of the raw water tank 10a. The pure water tank 10b is arranged outside the body 11, which can facilitate the user to drink a large amount of pure water in time, thereby eliminating the time of waiting for the water purifier 100 to purify water. The base 12 is used to install and fix the body 11 and some structures inside the body 11, especially the booster pump 42, the compressor 22 and other structural components with large mass, which are generally directly installed on the base 12. The raw water tank 10a is filled with water that has not been filtered by the water purification module 4, and the water in the pure water tank 10b is water filtered by the water purification module 4. Therefore, the water in the raw water tank 10a flows into the pure water tank 10b after being filtered by the water purification module 4, and is stored in the pure water tank 10b, which is convenient for the user to further pour it into a water cup for drinking. Among them, the top surfaces of the body 11, the pure water tank 10b and the raw water tank 10a are basically in the same plane. This design makes the structure of the water purifier 100 more reasonable, and trays, cups and other sundries can be placed on the water purifier 100.

[0052] Among them, the refrigeration module 2 refers to a device for cooling water, which can be implemented by a compressor 22 refrigeration system. The instant heating module 3 refers to a device for quickly heating water, which can be implemented by an electric heating element. The water purification module 4 refers to a device for filtering and purifying water, which can be implemented by a multi-stage filter element assembly 41. The reflux pump 6 refers to a device for pumping water in the cold water tank 21 back to the filter element assembly 41, which can be implemented by a small water pump.

[0053] The core innovation of the present application is to install the reflux pump 6 on the mounting frame 5 and adjacent to the filter element assembly 41. This layout design makes full use of the space around the filter element assembly 41, avoids the additional increase in the size of the body 1, and realizes the cold water reflux function. Through this innovative space utilization method, the technical problem of installing the reflux system in a limited space is solved.

[0054] Specifically, the working principle of the present application is as follows: the body 1 serves as the outer shell of the entire water purifier 100, and an installation cavity 1a is formed inside to accommodate various functional modules. The body 1 is composed of a fuselage 11 and a base 12. The fuselage 11 is mounted on the base 12, and a first water outlet 111 is opened on the front side. The cold water tank 21 of the refrigeration module 2 is installed in the installation cavity 1a for storing and cooling water. The instant heating module 3 is installed on the front side of the cold water tank 21 for quickly heating water. The water purification module 4 includes a filter element assembly 41 and a booster pump 42. The filter element assembly 41 is installed on the base 12 through a mounting frame 5, and an installation space 11a is formed on its lower side, and the booster pump 42 is installed in this space. The reflux pump 6 is installed on the mounting frame 5, adjacent to the filter element assembly 41, and is used to pump the water in the cold water tank 21 back to the filter element assembly 41 for re-filtration.

[0055] The key to this design is the location of the reflux pump 6. Installing the reflux pump 6 on the mounting frame 5 and adjacent to the filter element assembly 41 not only saves space, but also shortens the water connection distance and improves the reflux efficiency. At the same time, this layout is also convenient for maintenance and overhaul.

[0056] The technical solution of the present invention is to install the filter element on the mounting frame 5, and install the reflux pump 6 on the remaining mounting space 11a of the mounting frame 5, and make the reflux pump 6 adjacent to the filter element assembly 41 to fully utilize the space around the filter element assembly 41, avoid additional increase in the size of the body 1 of the water purifier 100, and realize cold water reflux, improve the taste of cold water stored in the cold water tank 21 for a long time, and improve the utilization rate of the internal space of the body 1 through reasonable structural settings.

[0057] In one embodiment, see Figure 2 and Figure 3 The mounting frame 5 includes a first mounting frame 515 and a second mounting frame 525 , the reflux pump 6 is mounted on the upper side of the first mounting frame 515 , and the height of the first mounting frame 515 is greater than the height of the second mounting frame 525 .

[0058] Specifically, this design scheme fully utilizes the space inside the water purifier 100 by dividing the mounting frame 5 into two parts with different heights. The first mounting frame 515 is relatively high and is used to install the reflux pump 6, while the second mounting frame 525 is relatively low and can be used to install other components or leave space. This structural design not only solves the installation problem of the reflux pump 6, but also improves the utilization efficiency of the internal space of the water purifier 100.

[0059] Specifically, the height of the first mounting bracket 515 is greater than that of the second mounting bracket 525. This height difference allows the reflux pump 6 to be installed at a higher position. Such a design has several advantages: first, it can avoid interference between the reflux pump 6 and other components at the bottom, reducing layout restrictions; second, the higher installation position can reduce the impact of water accumulation or humid environment on the reflux pump 6, thereby improving the service life and reliability of the reflux pump 6; third, this design can also provide more space for the pipe connection between the water inlet 61 and the second water outlet 62 of the reflux pump 6, facilitating the layout and maintenance of the pipes. This high and low design makes full use of the vertical space inside the water purifier 100, allowing the various components to be reasonably arranged within a limited space, thereby improving the overall space utilization.

[0060] In practical applications, the first mounting frame 515 and the second mounting frame 525 can be made of different materials and structural designs. For example, the first mounting frame 515 can be made of a stronger metal material to withstand the weight of the reflux pump 6 and the vibration during operation; while the second mounting frame 525 can be made of a lightweight material to reduce the overall weight. The two mounting frames 5 can be a split design or an integrally formed structure with different heights.

[0061] In one embodiment, see Figure 3 and Figure 5 The reflux pump 6 is connected to the first mounting bracket 515 via a connecting member 7 .

[0062] In this regard, the present application further proposes that the reflux pump 6 is connected to the first mounting bracket 515 via a connecting member 7 .

[0063] Specifically, the connector 7 can be designed in a variety of shapes and structures to meet different installation requirements. For example, the connector 7 can be a U-shaped bracket, one end of which is fixed to the first mounting frame 515, and the other end surrounds and is fixed to the reflux pump 6. Alternatively, the connector 7 can be a flat plate structure, one side of which is fixed to the first mounting frame 515, and the other side of which is fixed to the reflux pump 6. The material of the connector 7 can be metal or high-strength plastic to ensure sufficient strength and durability.

[0064] The connection between the connecting member 7 and the first mounting frame 515 can be bolted, snap-fitted or welded. These different connection methods can be selected according to actual needs and production processes to achieve the best installation effect and production efficiency.

[0065] The connection between the reflux pump 6 and the connecting member 7 can also be adopted in various ways. For example, a groove or a buckle structure can be designed on the connecting member 7 so that the reflux pump 6 can be firmly embedded therein. Alternatively, the reflux pump 6 can be directly fixed to the connecting member 7 by bolts. This design can not only ensure the stability of the reflux pump 6, but also facilitate subsequent maintenance and replacement.

[0066] By using the connector 7, the installation position of the reflux pump 6 can be more flexible. The installation height and angle of the reflux pump 6 can be adjusted according to the actual situation of the internal space of the water purifier 100 to optimize the waterway layout and improve the overall performance of the water purifier 100. At the same time, the design of the connector 7 can also take into account the shock absorption function. By adding a shock-absorbing pad or an elastic structure to the connector 7, the vibration generated during the operation of the reflux pump 6 can be effectively reduced, the operating stability of the water purifier 100 can be improved, and the noise can be reduced.

[0067] In one embodiment, please continue to refer to Figure 3 and Figure 5 The connecting member 7 includes a sleeve portion 71 sleeved on the reflux pump 6 and a mounting ear 72 connected to the sleeve portion 71, and the mounting ear 72 is screwed to the first mounting frame 515 by screws.

[0068] First, the sleeve portion 71 can tightly wrap the reflux pump 6 to provide good support and fixing effect. The sleeve portion 71 can be customized according to the shape of the reflux pump 6 to ensure the fit between the reflux pump 6 and reduce shaking and displacement during installation.

[0069] Secondly, the design of the mounting ears 72 increases the contact area between the connector 7 and the first mounting bracket 515, thereby improving the stability of the overall structure. The mounting ears 72 can be designed to be multiple and distributed at different positions of the sleeve portion 71 to further enhance the connection strength.

[0070] Again, the mounting ear 72 is screwed to the first mounting bracket 515 by screws, so as to realize a detachable mounting mode. This mode is not only firmly mounted, but also convenient for later maintenance and replacement. When the reflux pump 6 needs to be repaired or replaced, it only needs to be removed, which is simple and quick to operate.

[0071] In addition, this connection mode also has a certain adjustment space. By adjusting the tightness of the screw, the installation position and angle of the reflux pump 6 can be fine-tuned to adapt to different installation environments and requirements.

[0072] In a specific implementation, the sleeve portion 71 can be made of elastic material, such as rubber or silicone, to increase its wrapping and shock absorption effect on the reflux pump 6. The mounting ear 72 can be made of metal material, such as stainless steel or aluminum alloy, to improve strength and durability. The screws can be made of rust-proof materials, such as stainless steel screws, to extend the service life. As a preferred embodiment, the sleeve portion 71 can be designed to be semi-cylindrical to match the shape of the reflux pump 6.

[0073] Through this design, the reflux pump 6 can be stably mounted on the first mounting frame 515, effectively solving the problem of limited installation space 11a and insufficient installation stability. At the same time, this detachable installation method is also convenient for later maintenance and replacement, thereby improving the service life and maintenance efficiency of the entire water purifier 100.

[0074] In one embodiment, see Figures 2 to 5 The axial direction of the reflux pump 6 is consistent with the height direction of the fuselage 11, and the reflux pump 6 is provided with a water inlet 61 and a second water outlet 62 toward the base 12. The water inlet 61 and / or the second water outlet 62 are provided with a first joint 63, and the first mounting frame 515 next to the first joint 63 is recessed toward the filter element assembly 41 to form a first avoidance space 5a.

[0075] This design has many advantages and technical effects. First, the axial direction of the reflux pump 6 is aligned with the height direction of the body 11, which can make full use of the vertical space of the water purifier 100 and reduce the horizontal occupancy, so that the reflux pump 6 can be better installed in a limited space. Secondly, the reflux pump 6 opens a water inlet 61 and a second water outlet 62 toward the base 12. This layout can simplify the water connection, reduce the bends and length of the pipeline, and is conducive to improving water flow efficiency and reducing pressure loss.

[0076] In addition, the first joint 63 is provided at the water inlet 61 and / or the second water outlet 62, which can facilitate the connection and disassembly of the water pipe, and facilitate maintenance and replacement. More importantly, the first mounting frame 515 beside the first joint 63 is recessed toward the filter element assembly 41 to form a first avoidance space 5a. This design cleverly solves the problem of possible interference between the joint and the mounting frame 5. The setting of the avoidance space not only provides an installation space 11a for the joint, but also reduces the volume of the overall structure, making the installation of the reflux system more compact.

[0077] In one embodiment, see Figure 3 and Figure 4The first mounting frame 515 includes a fixing portion 511, a connecting portion 512, an avoiding portion 513 and a bending portion 514 which are connected in sequence. The opposite ends of the fixing portion 511 are respectively fixed to the filter element assembly 41 and the base 12. The avoiding portion 513 is located beside the first joint 63. An angle is formed between the bending portion 514 and the avoiding portion 513. The bending portion 514 has a flange 514a. The mounting ear 72 is fixedly installed on the flange 514a.

[0078] It should be noted that this structural design has multiple advantages. First, the two ends of the fixing portion 511 are respectively fixed to the filter element assembly 41 and the base 12, providing a stable support. The length of the connecting portion 512 can be adjusted as needed to adapt to different installation spaces 11a. The setting of the avoidance portion 513 cleverly avoids the first joint 63, ensuring smooth connection of the pipeline. The angle formed between the bending portion 514 and the avoidance portion 513 increases the rigidity of the structure and improves the overall stability. The flange 514a on the bending portion 514 provides a firm mounting point for the mounting ear 72, further enhancing the fixing effect of the reflux pump 6. Among them, the formation of the bending portion 514 also provides a larger space for the installation of the reflux pump 6, thereby avoiding the problem of insufficient screw connection space.

[0079] This design not only solves the installation problem of the reflux pump 6, but also makes full use of the limited space. Through the clever structural design, the reflux pump 6 is stably installed while avoiding interference with other components. For example, the setting of the avoidance portion 513 ensures that the first connector 63 has sufficient operating space, which is convenient for the connection and maintenance of the pipeline.

[0080] Compared with the prior art, the design of the present application has significant advantages. It is often difficult to reasonably arrange the reflux system of the traditional water purifier 100 in a limited space, which often leads to complex structure, difficult installation or inconvenient maintenance. The present application not only solves the problem of space utilization through clever structural design, but also improves the installation stability and maintenance convenience of the reflux pump 6. In particular, the multi-part design of the first mounting frame 515, each part has its specific function, and together they form an efficient, compact and easy-to-maintain reflux pump 6 installation structure. This design not only improves the overall performance of the water purifier 100, but also helps to extend the service life of the equipment and reduce maintenance costs.

[0081] In one embodiment, see Figure 2 The flange 514a is closer to the fuselage 11 than the fixing portion 511. By arranging the flange 514a close to the fuselage 11, it can be seen that although the reflux pump 6 is close to the outer shell of the fuselage 11, a certain distance is still retained, which can improve the compactness of the internal structure of the fuselage 11.

[0082] In one embodiment, see Figure 2 and Figure 3 A waterway plate 8 is provided on the lower side of the filter element assembly 41, and a second joint 81 is provided on the waterway plate 8 toward the fixing portion 511. The fixing portion 511 is provided with an opening 511a for the second joint 81 to pass through, and the second joint 81 is connected to the first joint 63.

[0083] Specifically, the waterway plate 8, as a part of the filter element assembly 41, plays the role of connecting and distributing water flow. The second connector 81 provided on the waterway plate 8 faces the fixing portion 511, so that it can be easily connected with the opening 511a on the fixing portion 511. The opening 511a provided on the fixing portion 511 allows the second connector 81 to pass through, thereby connecting with the first connector 63 on the reflux pump 6. This design allows the waterway to form a complete loop from the filter element assembly 41 to the reflux pump 6.

[0084] Furthermore, the second joint 81 may be designed as a quick joint, such as a snap-on or threaded joint, for easy installation and removal. The size of the opening 511a may be slightly larger than the outer diameter of the second joint 81 for easy adjustment and installation. In order to ensure sealing, a sealing ring or a gasket may be provided between the second joint 81 and the opening 511a.

[0085] Thus, after the water flows out of the filter element assembly 41, it can pass through the second joint 81 on the waterway plate 8, through the opening 511a on the fixing portion 511, and then connect to the first joint 63 on the reflux pump 6. This design not only ensures the continuity of the waterway, but also facilitates maintenance and replacement of components. For example, when the filter element needs to be replaced, the filter element assembly 41 can be easily removed by simply disconnecting the second joint 81 from the first joint 63.

[0086] As a preferred embodiment, the second joint 81 can be made of elastic material, such as food-grade silicone or rubber, so that it can provide a certain buffering effect while ensuring the sealing, and reduce the impact of vibration on the connection. In addition, the second joint 81 can be designed as a rotatable structure to meet the needs of different installation angles.

[0087] Through this design, the present application not only solves the problem of connection between the filter element assembly 41 and the reflux pump 6, but also improves the integration and compactness of the entire system. Compared with the traditional connection method, the solution of the present application reduces the use of pipelines, reduces the risk of leakage, and is also convenient for maintenance and cleaning. In addition, this design can also effectively reduce the space occupied inside the water purifier 100, which is conducive to achieving a more compact overall layout.

[0088] In one embodiment, see Figure 2The filter element assembly 41 includes a first filter element 411 and a second filter element 412 arranged in parallel, and the axial directions of the first filter element 411 and the second filter element 412 are consistent with the height direction of the water purifier 100.

[0089] In the water purifier 100 of the present application, the filter element assembly 41 includes a first filter element 411 and a second filter element 412 arranged in parallel, and the axial direction of the first filter element 411 and the second filter element 412 is consistent with the height direction of the water purifier 100. This design can effectively utilize the vertical space of the water purifier 100, making the arrangement of the filter element assembly 41 more compact and efficient.

[0090] Specifically, the first filter element 411 and the second filter element 412 are arranged side by side to reduce the horizontal space occupied by the water purifier 100, and the vertical space of the water purifier 100 can be fully utilized by aligning their axial direction with the height direction of the water purifier 100. This arrangement can not only save space, but also simplify water connection and improve water purification efficiency.

[0091] The first filter element 411 is designed as a composite filter element composed of a pre-filter element and a post-filter element, which is used to remove larger particles and suspended matter in the water, and the taste of the water can also be adjusted through the post-filter element, while the second filter element 412 can be designed as a reverse osmosis filter element, which is used to further remove tiny impurities and salt ions dissolved in water. This parallel arrangement allows the water flow to pass through the two filter elements in sequence, achieving a more comprehensive purification effect.

[0092] In addition, the parallel arrangement of the first filter element 411 and the second filter element 412 can also optimize the weight distribution of the water purifier 100 and improve the overall stability. Since the weight of the two filter elements is distributed on both sides of the water purifier 100, the imbalance problem caused by excessive weight on one side can be avoided.

[0093] In one embodiment, see Figure 2 and Figure 3 The water purification module 4 also includes an inlet solenoid valve 43 and a wastewater solenoid valve 44, and the inlet solenoid valve 43 and the wastewater solenoid valve 44 are both fixed to the base 12 through a support frame 45, and the inlet solenoid valve 43 and the wastewater solenoid valve 44 are located between the filter element assembly 41 and the reflux pump 6.

[0094] On the basis of the above embodiment, the water purification module 4 of the present application further includes a water inlet solenoid valve 43 and a waste water solenoid valve 44, both of which are fixed to the base 12 via a support frame 45, and the water inlet solenoid valve 43 and the waste water solenoid valve 44 are located between the filter element assembly 41 and the reflux pump 6. This arrangement makes full use of the space between the filter element assembly 41 and the reflux pump 6, and effectively solves the problem of limited installation space 11a of the reflux system.

[0095] Specifically, the water inlet solenoid valve 43 is used to control the flow of raw water into the water purification module 4, and the wastewater solenoid valve 44 is used to control the discharge of wastewater generated during the water purification process. The two solenoid valves are fixed to the base 12 through the support frame 45 to ensure their stability. At the same time, placing them between the filter element assembly 41 and the reflux pump 6 can make full use of the space in this area and avoid occupying the space of other functional modules.

[0096] This arrangement can also simplify the water connection. The water inlet solenoid valve 43 can be directly connected to the water inlet 61 of the filter element assembly 41, and the waste water solenoid valve 44 can be connected to the waste water outlet of the filter element assembly 41. This can reduce the length and complexity of the pipeline and further save space. In addition, the two solenoid valves only need to be installed through one support frame 45, which simplifies the installation steps and installation structure.

[0097] In one embodiment, see Figure 6 and Figure 7 The refrigeration module 2 further includes a compressor 22 and a heat dissipation component 23 , the compressor 22 and the heat dissipation component 23 are fixed to the base 12 , and the cold water tank 21 is installed on the upper side of the compressor 22 and the heat dissipation component 23 .

[0098] It should be noted that the lower part of the cold water tank 21 has sufficient installation space 11a. In order to reduce the pipeline, the compressor 22 and the heat dissipation component 23 used for heat exchange with the cold water tank 21 are arranged under the cold water tank 21, which can reduce the length of the pipeline and form a more compact refrigeration module 2 that occupies a smaller space. In addition, the compressor 22 vibrates more obviously when working. The compressor 22 can be installed on the base 12 through a vibration-damping pad to reduce the vibration amplitude of the compressor 22.

[0099] In one embodiment, see Figure 7 An ice-making module is arranged in the cold water tank 21, an ice outlet 112 is arranged on the front side of the machine body 1, and the ice outlet 112 is located beside the first water outlet 111. The cold water tank 21 includes a main box body 211 and an ice outlet channel 212 protruding toward the ice outlet 112. The instant heating module 3 is installed on the front side of the main box body 211 and the instant heating module 3 is located at the lower side of the ice outlet channel 212.

[0100] It should be noted that a module for making ice is provided on the upper side of the cold water tank 21, and the ice-making module has an ice outlet 112, which is located next to the first water outlet 111, so that the remaining cold water after the ice-making module can flow into the bottom of the cold water tank 21. Considering that the length of the ice-making channel is relatively long and the ice-making module protrudes from the main box body 211 of the cold water tank 21, the heating module 3 is installed on the front side of the main box body 211 and is located on the lower side of the ice outlet channel 212, making full use of the installation space 11a on the lower side of the ice outlet channel 212.

[0101] Optionally, see Figure 6 The water purifier 100 further includes an electric control module 9. A second escape space 211a is formed by a depression on one side of the main box body 211. The electric control module 9 is installed in the main box body 211 and is at least partially located in the second escape space 211a.

[0102] In addition, a space for avoidance is provided in a recess on one side of the main box 211, so that the electric control module 9 is installed in the main box 211, wherein the electric control module 9 is located between the main box 211 and the water tank accommodating position 113, so that the electric control module 9 is away from the waterway, and the electric control module 9 is prevented from being disturbed by the waterway, thereby causing the circuit board to be corroded. Such a design effectively utilizes the installation space 11a in the installation cavity 1a.

[0103] In one embodiment, see Figure 1 and 8 A water tank accommodating position 113 is opened on the left side or the right side of the body 11 , and the water purifier 100 also includes a raw water tank 10a and a pure water tank 10b , and the raw water tank 10a and the pure water tank 10b are both accommodated in the water tank accommodating position 113 .

[0104] Among them, the distribution mode of the raw water tank 10a and the pure water tank 10b can be further optimized, for example, the raw water tank 10a and the pure water tank 10b can be located on the same side of the fuselage 11, or respectively on different sides of the fuselage 11. As a preferred embodiment, in this embodiment, in order to save the space occupied by the water purifier 100, especially the space occupied by the water purifier 100 in its front and rear directions, the raw water tank 10a and the pure water tank 10b are arranged on the same side of the fuselage 11. , so as to further reduce the space occupied by the water purifier 100 on the countertop. In addition, the detachable design of the pure water tank 10b can be realized in a variety of ways. For example, the pure water tank 10b can be connected to the fuselage 11 by means of buckles, slide rails or magnetic suction, so as to facilitate the user to disassemble and install. The raw water tank 10a can also be detachably arranged on the raw water tank 10a. Specifically, the raw water tank 10a and the pure water tank 10b can be arranged on the left side of the fuselage 11, or on the right side of the fuselage 11. This arrangement can be selected according to actual needs. The same technical effect can be achieved by arranging the raw water tank 10a and the pure water tank 10b on the left side of the fuselage 11, or arranging the raw water tank 10a and the pure water tank 10b on the right side of the fuselage 11.

[0105] By uniformly arranging the raw water tank 10a and the pure water tank 10b on one side of the body 11, the structural layout inside the body 11 is simplified, and the space occupied in the left and right directions of the body 11 is reduced. Thus, the technical problem of the distribution of the raw water tank 10a and the pure water tank 10b in the left and right directions of the body 11 is solved. Compared with the prior art, the technical solution of the present application optimizes the space utilization inside the body 11 while maintaining the function of the water purifier 100, so that the space occupied by the water purifier 100 on the countertop is more compact, which is particularly suitable for tables or counters with cramped space.

[0106] In one embodiment, see Figure 1 The pure water tank 10b is located at the front side of the raw water tank 10a, and a handle is provided on the front side of the pure water tank 10b.

[0107] The handle disposed on the front side of the pure water tank 10b can be in a variety of forms. For example, the handle can be an embedded type or an externally protruding type. Specifically, the embedded handle can be designed in a groove form, and the externally protruding handle can be designed in an arc or straight line shape. As a preferred embodiment, the handle can be made of a non-slip material to increase the comfort and stability of the user's grip. In addition, the position of the handle can be adjusted according to the overall design of the pure water tank 10b. For example, the handle can be disposed on the top or side of the pure water tank 10b to facilitate the user to disassemble and move it at different angles.

[0108] Therefore, this technical solution effectively reduces the longitudinal space occupied by the water purifier 100 on the countertop by setting the pure water tank 10b on the front side of the original water tank 10a and equipping it with a handle, especially on a table or counter with cramped space, so as to better accommodate the water purifier 100. The handle set on the front side of the pure water tank 10b makes it convenient for the user to disassemble and move the pure water tank 10b, further improving the convenience of use. Through this layout and design, the present application effectively solves the problem that the pure water tank 10b occupies too much space outside the body 11 of the water purifier 100, while improving the user experience. Compared with the prior art, the present application has significant advantages in space utilization and user convenience of operation.

[0109] In one embodiment, see Figure 8 and Fig. 9 The body 1 further includes a partition 13, and the partition 13 is installed between the pure water tank 10b and the raw water tank 10a.

[0110] The partition 13 can be made of a variety of materials, such as plastic, metal or composite materials. The selection of specific materials can be optimized according to the overall structure of the fuselage 11 and the strength requirements of the partition 13. The shape and size of the partition 13 can be adjusted according to the specific layout of the pure water tank 10b and the raw water tank 10a to ensure effective separation between the two. As a preferred embodiment, the partition 13 can be designed as a detachable structure to facilitate cleaning and maintenance by the user. In addition, the partition 13 can be installed in a variety of ways such as snap-on, screw fixing or bonding. The specific installation method can be selected according to the internal structure of the fuselage 11 and the material of the partition 13.

[0111] By setting the partition 13, the spatial layout between the pure water tank 10b and the raw water tank 10a is effectively optimized, avoiding interference between the pure water tank 10b and the raw water tank 10a when taking and placing. The partition 13 can not only ensure the orderly arrangement of the pure water tank 10b and the raw water tank 10a inside the body 11, but also improve the overall structural compactness and use efficiency of the water purifier 100. Compared with the prior art, the technical solution of the present application solves the technical problem of unreasonable spatial layout between the pure water tank 10b and the raw water tank 10a through the introduction of the partition 13, so that the water purifier 100 can be better adapted and installed in a cramped space environment.

[0112] In one embodiment, see Fig. 9 The maximum length of the water purifier 100 in the front-to-rear direction is L, the maximum width of the water purifier 100 in the left-to-right direction is T, and L and T satisfy 1≤L / T≤1.4.

[0113] Specifically, the ratio of L to T is limited to between 1 and 1.4. This design enables the water purifier 100 to optimize its space occupation on the countertop while maintaining functionality. For example, when L / T is 1, the dimensions of the water purifier 100 in the front-to-back direction and the left-to-right direction are equal, forming a relatively compact structure; when L / T is 1.4, the length of the water purifier 100 in the front-to-back direction is slightly greater than the width in the left-to-right direction, but it remains within a reasonable range to avoid excessive space occupation. As a preferred embodiment, the ratio of L / T can be further optimized to between 1.2 and 1.3 to achieve a better balance between compactness and functionality.

[0114] Thus, the technical solution makes the water purifier 100 more suitable for a space-constrained environment by limiting the ratio of L and T, and solves the problem of excessive space occupation caused by unreasonable size ratio in the prior art. Compared with the prior art, the solution significantly optimizes the space occupation of the water purifier 100 while maintaining its functionality, making it more suitable for use in limited countertop space.

[0115] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
