Description

Technical Field

[0001] This utility model relates to the field of water supply, and in particular to a water purification device. Background Technology

[0002] With increasing health awareness and improved living standards, water purifiers that provide safe and convenient drinking water have become essential appliances in modern households. Among these, water purifiers that can directly output hot purified water have gained widespread market application due to their ability to meet users' immediate demand for hot water. In existing technology, such hot water output water purifiers typically integrate core components such as a filter unit, a water storage unit, and a water pump. Their working principle is as follows: the filter unit filters and purifies the raw water, then delivers the purified water to the water storage unit; the water storage unit has a built-in heating module that heats and maintains the purified water at a constant temperature; when a user needs hot purified water, the water pump starts to increase the pressure of the hot purified water in the water storage unit, allowing the hot purified water to be smoothly output to the user's water intake. Considering the limitations of home installation, these water purification devices are mostly designed for under-cabinet installation. To adapt to the internal space of the cabinet, the relevant technology effectively controls the overall height and width of the device by distributing the filter unit, water storage unit and water pump in a vertical direction, so that it can be easily embedded into the space under the cabinet of most families, taking into account both functionality and installation convenience.

[0003] However, with the diversification of users' lifestyles, water purifiers that only output hot water are no longer sufficient to meet comprehensive usage needs. A clear demand for "dual-output" water purifiers—that is, devices that simultaneously output both hot and cold water while maintaining convenient under-cabinet installation—has emerged in the market. To achieve the cold water output function, the water purifier needs to add a cold water preparation component to the existing hot water purification system, which is relatively large. This new requirement directly poses a serious challenge to the component distribution scheme of existing water purifiers: the original vertically distributed structure based on "water storage unit-pump-filter unit" can only accommodate simplified systems without a cooling component; when a large cooling component is integrated, the overall size of the device increases significantly, potentially exceeding the installation space under some users' regular cabinets. Therefore, how to rationally optimize the structural layout of the water purifier while integrating hot and cold water functions to control its overall size and meet the under-cabinet installation requirements has become an urgent technical problem to be solved in the current development of water purifier technology.

[0056] The details of this utility model can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of this utility model described herein are for illustrative purposes only and should not be construed as limiting the utility model in any way. Under the teachings of this utility model, those skilled in the art can conceive of any possible modifications based on this utility model, and these should all be considered to fall within the scope of this utility model.

[0057] To address the issue of bulky water purification devices being inconvenient to install under cabinets, this application proposes a water purification device. Figure 1 This is a front view of the water purification device in one embodiment of the present invention (partial casing not shown). Figure 2 This is a right view of the water purification device in one embodiment of the present invention (partial casing not shown). Figure 3 This is a left view (partial casing not shown) of the water purification device in one embodiment of the present invention. Figures 1 to 3 As shown, the water purification device may include: a housing 1; a first water storage unit 2 and a filter element 3 arranged vertically within the housing 1, and a cold water output component 4, wherein the center of the first water storage unit 2 and the center of the filter element 3 are spaced apart in the width direction of the housing 1, and at least part of the cold water output component 4 is located at the bottom of the housing 1; and a pump device 5 arranged within the housing 1, wherein the pump device 5 is located in the width direction of the housing 1 on the side of the first water storage unit 2 facing the filter element 3 or on the side of the filter element 3 facing the first water storage unit 2.

[0058] In this application, the first water storage unit 2, filter element 3, and cold water output component 4 are distributed vertically, with at least a portion of the cold water output component 4 located at the bottom of the housing 1. This effectively controls the overall height of the water purification device, minimizing any increase. Secondly, by creating a gap between the center of the first water storage unit 2 and the center of the filter element 3 in the width direction of the housing 1, a certain space is created on either the side of the first water storage unit 2 facing the filter element 3 or the side of the filter element 3 facing the first water storage unit 2. In this case, the pump device 5 can be positioned in the width direction of the housing 1 on either the side of the first water storage unit 2 facing the filter element 3 or the side of the filter element 3 facing the first water storage unit 2. Thus, the entire water purification device only requires a slight increase in width to accommodate the first water storage unit 2, filter element 3, cold water output component 4, and pump device 5. Finally, placing at least a portion of the relatively heavy and potentially vibrating cold water output component 4 at the bottom of the housing 1 further enhances the stability of the water purification device.

[0059] like Figures 1 to 3As shown, the water purification device includes: a housing 1, a first water storage unit 2, a filter element 3, a cold water output component 4, and a pump device 5. The housing 1 houses the first water storage unit 2, the filter element 3, the cold water output component 4, and the pump device 5. Generally, the housing 1 is roughly rectangular to facilitate installation under a cabinet. The filter element 3 filters raw water to form purified water, which can be supplied to the first water storage unit 2 and the cold water output component 4. The first water storage unit 2 stores the input purified water, and the pump device 5 pressurizes the water flowing into the filter element 3 to increase the filtration rate. Generally, the pump device 5 can be a booster pump. The cold water output component 4 receives the purified water output from the filter element 3 and cools it to cold water, which can be supplied to the user when needed. Alternatively, the water purification device may include an output pump that can output water from the first water storage unit 2 to the user.

[0060] In one feasible implementation, the cold water output assembly 4 may include a second water storage unit 41 and at least a portion of a refrigeration system. The second water storage unit 41 is used to receive and store the purified water output from the filter cartridge 3. The refrigeration system is used to cool the purified water stored in the second water storage unit 41 to make it cold water. The refrigeration system may be a system formed by a compressor 42, an evaporator, a condenser 43, and a throttling element, as is common in the art. At least a portion of the refrigeration system includes a compressor 42, and the second water storage unit 41 and the compressor 42 are located at approximately the same height and distributed along the depth direction of the housing 1. This allows for optimal optimization of the dimensions of the cold water output assembly 4 in the height direction and full utilization of the space in the depth direction. Alternatively, the axis of the compressor 42 and the axis of the second water storage unit 41 extend along the height direction of the housing 1, thereby fully utilizing the space in the depth direction and minimizing the dimensions of the water purification device in the height direction.

[0061] The evaporator in the refrigeration system can exchange heat with the water stored in the second water storage unit 41 to cool the purified water stored in the second water storage unit 41. For example, the evaporator can be installed in the second water storage unit 41, or it can be in close contact with the side wall of the second water storage unit 41 or indirectly exchange heat through a material with high thermal conductivity.

[0062] As an option, the first water storage unit 2 has a heating component that can heat the water in the first water storage unit 2 so that the water stored in the first water storage unit 2 becomes hot water, which is then supplied to the user by an output pump when the user needs hot water.

[0063] like Figures 1 to 3As shown, the first water storage unit 2, the filter element 3, and the cold water output component 4 are arranged inside the housing 1 and distributed vertically. The axes of the first water storage unit 2 and the filter element 3 extend along the depth direction of the housing 1. At least part of the cold water output component 4 is located at the bottom of the housing 1, which makes the water purification device more stable. Specifically, the housing 1 can be divided into three regions vertically: top, middle, and bottom, with at least part of the cold water output component 4 located at the bottom. The first water storage unit 2 is located above the filter element 3; or, the first water storage unit 2 is located below the filter element 3. That is, the first water storage unit 2 can be located at the top, and the filter element 3 can be located in the middle; or, the filter element 3 can be located at the top, and the first water storage unit 2 can be located in the middle. When the first water storage unit 2 can be located at the top, and the filter element 3 can be located in the middle, the filter element 3 can separate the first water storage unit 2 (used for storing hot water) and the second water storage unit 41 (used for storing cold water) by a certain distance, thereby avoiding mutual influence between the heat and cold of the two.

[0064] In the above embodiments, as feasible, the first water storage unit 2 has a generally circular or elliptical cross-section in the radial direction; the filter element 3 has a generally circular or elliptical cross-section in the radial direction.

[0065] The center of the first water storage unit 2 and the center of the filter element 3 are spaced apart in the width direction of the housing 1. That is, in the width direction, the center of the first water storage unit 2 is slightly to the left and the center of the filter element 3 is slightly to the right. This creates some space in the width direction of the housing 1 on either the side of the first water storage unit 2 facing the filter element 3 or the side of the filter element 3 facing the first water storage unit 2. The pump device 5 can be placed in one of these two spaces. Thus, the entire water purification device only needs a slight increase in width to accommodate the first water storage unit 2, the filter element 3, the cold water output component 4, and the pump device 5. In the above embodiment, the axis of the pump device 5 extends along the depth direction of the housing 1.

[0066] Alternatively, when the first water storage unit 2 is located above the filter element 3, the lowest point of the first water storage unit 2 is higher than the highest point of the filter element 3. Or, when the first water storage unit 2 is located below the filter element 3, the lowest point of the filter element 3 is higher than the highest point of the first water storage unit 2. This structure minimizes the overall width dimension of the water purification device.

[0067] As a feasible arrangement, when the first water storage unit 2 is located above the filter element 3, in the width direction of the housing 1, the edge of the filter element 3 facing the first water storage unit 2 is located between the two sides of the first water storage unit 2; in the width direction of the housing 1, the edge of the first water storage unit 2 facing the filter element 3 is located between the two sides of the filter element 3; in the width direction of the housing 1, the edge of the pump device 5 facing the first water storage unit 2 is located between the two sides of the filter element 3. This structure allows the first water storage unit 2, the filter element 3, and the pump device 5 in the water purification device to be more compact, minimizing the overall width dimension of the water purification device.

[0068] In one embodiment, when the pump device 5 is located on the side of the first water storage unit 2 facing the filter element 3 in the width direction of the housing 1, and the first water storage unit 2 is located above the filter element 3, the uppermost point of the pump device 5 is lower than or equal to the uppermost point of the first water storage unit 2 in the height direction of the housing 1, and the side of the pump device 5 away from the first water storage unit 2 does not exceed the side of the filter element 3 away from the first water storage unit 2 in the width direction of the housing 1. In another embodiment, when the pump device 5 is located on the side of the filter element 3 facing the first water storage unit 2 in the width direction of the housing 1, and the first water storage unit 2 is located above the filter element 3, the lowermost point of the pump device 5 is higher than or equal to the lowermost point of the filter element 3 in the height direction of the housing 1, and the side of the pump device 5 away from the filter element 3 does not exceed the side of the first water storage unit 2 away from the filter element 3 in the width direction of the housing 1. These methods optimize the dimensions of the pump device 5, the first water storage unit 2, and the filter element 3 in both the height and width directions.

[0069] Similarly, in another embodiment, when the pump device 5 is located on the side of the first water storage unit 2 facing the filter element 3 in the width direction of the housing 1, and the first water storage unit 2 is located below the filter element 3, in the height direction of the housing 1, the lowest point of the pump device 5 is higher than or equal to the lowest point of the first water storage unit 2, and in the width direction of the housing 1, the side of the pump device 5 away from the first water storage unit 2 does not exceed the side of the filter element 3 away from the first water storage unit 2. In yet another embodiment, when the pump device 5 is located on the side of the filter element 3 facing the first water storage unit 2 in the width direction of the housing 1, and the first water storage unit 2 is located below the filter element 3, in the height direction of the housing 1, the highest point of the pump device 5 is lower than or equal to the highest point of the filter element 3, and in the width direction of the housing 1, the side of the pump device 5 away from the filter element 3 does not exceed the side of the first water storage unit 2 away from the filter element 3.

[0070] In the above embodiments, as feasible, the center of the pump device 5 can be located between the center of the first water storage unit 2 and the center of the filter element 3 in the height direction of the housing 1. In this way, a certain space for accommodating the pump device 5 can be formed between the first water storage unit 2 and the filter element 3 in the height direction of the housing 1, so that the pump device 5 can be close to the adjacent first water storage unit 2 or filter element 3 in the width direction.

[0071] In one alternative implementation, such as Figure 3 As shown, the water purification device may include a frame assembly 6 disposed within a housing 1. The frame assembly 6 has a first receiving cavity and a second receiving cavity extending along the depth direction of the housing 1. A first water storage unit 2 is disposed in the first receiving cavity, and a filter element 3 is disposed in the second receiving cavity. The frame assembly 6 is used to support and limit the components such as the first water storage unit 2 and the filter element 3. The side of the frame assembly 6 forming the first receiving cavity facing the filter element 3 has a first receiving gap 11 between itself and the housing 1, and a pump device 5 is disposed in the first receiving gap 11; alternatively, the side of the frame assembly 6 forming the second receiving cavity facing the first water storage unit 2 has a second receiving gap 12 between itself and the housing 1, and the pump device 5 is disposed in the second receiving gap 12.

[0072] In one alternative implementation, such as Figure 2 As shown, the water purification device may include a control circuit board 7. When the pump device 5 is disposed in the first receiving gap 11, the frame assembly 6 forming the second receiving cavity has a second receiving gap 12 between the side facing the first water storage unit 2 and the housing 1, and the control circuit board 7 may be disposed in the second receiving gap 12. When the pump device 5 is disposed in the second receiving gap 12, the frame assembly 6 forming the first receiving cavity has a first receiving gap 11 between the side facing the filter element 3 and the housing 1, and the control circuit board 7 is disposed in the first receiving gap 11. In this embodiment, the control circuit board 7 may extend along the height and depth directions of the housing 1. By means of the above, the layout of the various components in the water purification device can be optimized to minimize the volume of the water purification device.

[0073] In one optional implementation, Figure 5 This is a perspective structural diagram of the water purification device in one embodiment of the present invention (partial housing 1 is not shown), as follows: Figure 5As shown, the bottom and / or rear sidewall of the housing 1 has a first perforated structure 13. The left sidewall and / or right sidewall of the housing 1 has a second perforated structure. The condenser 43 in the refrigeration system is disposed inside the housing 1. A ventilation channel is formed inside the housing 1, passing through the condenser 43. One end of the ventilation channel is connected to the first perforated structure 13, and the other end of the ventilation channel is connected to the second perforated structure. Through the above structure, the heat dissipation effect of the condenser 43 can be improved, thereby improving the refrigeration effect of the refrigeration system.

[0074] In the above embodiment, the second perforated structure can be located at the height corresponding to the compressor 42 of the housing 1. When the rear sidewall of the housing 1 has the first perforated structure 13, the first perforated structure 13 is located at the height corresponding to the compressor 42 of the housing 1. The condenser 43 can be disposed close to the compressor 42, such as between the compressor 42 and the second water storage unit 41 in the depth direction, which facilitates shortening the length of the ventilation channel and reducing air resistance. Furthermore, Figure 6 This is a partial structural diagram of the cold water output component 4 in an embodiment of the present invention, as shown below. Figure 6 As shown, the water purification device may include: a fan 8 disposed within the housing 1, which draws in outside air and allows it to flow through a ventilation channel to dissipate heat from the condenser 43. The fan 8 is arranged parallel to the condenser 43. The fan 8 and the condenser 43 are positioned corresponding to the second perforated structure. In the depth direction of the housing 1, the position of the first perforated structure 13 corresponds to the position of the compressor 42.

[0075] In one alternative implementation, such as Figure 2 and Figure 4 As shown, the water purification device may include a water circuit board assembly 9, which is located behind the first water storage unit 2, the filter element 3, and the cold water output assembly 4 in the depth direction of the housing 1. The water circuit board assembly 9 has a water inlet port 91 for inputting water from a water source into the water purification device. The water inlet port 91 can be located on the rear side wall of the housing 1, which facilitates connection to a water source via a water pipe and also helps to improve the aesthetics of the water purification device.

[0076] As a feasible option, filter element 3 may include at least a filtration unit capable of discharging wastewater. For example... Figure 4 As shown, the corresponding water circuit board assembly 9 may have a wastewater discharge port 92. The wastewater discharge port 92 is used to discharge the wastewater generated by the filter unit into the water purification device. The wastewater discharge port 92 is located on the rear side wall of the housing 1, which facilitates the discharge of wastewater into the house's drain pipe through the water pipe and also helps to improve the aesthetics of the water purification device.
