Description

Technical Field

[0001] This utility model relates to the field of dishwashers, and in particular to a water treatment system and a dishwasher. Background Technology

[0002] Traditional dishwashers typically include a water softener in their water circuit. The softener usually consists of a brine chamber and a resin chamber. In the resin chamber, sodium ions from the resin replace calcium and magnesium ions in the water. In the brine chamber, brine is introduced via a solenoid valve to replace calcium and magnesium ions on the resin, restoring its softening effect. However, this system requires discharging high-concentration brine, which is environmentally unfriendly. Furthermore, it necessitates the use of additional tap water to remove the brine, resulting in water waste. Utility Model Content

[0003] Therefore, it is necessary to provide a water treatment system and dishwasher to address the problems of traditional water treatment systems that require the discharge of high-concentration brine, which is environmentally unfriendly, and also require additional tap water to remove the brine, resulting in water waste.

[0004] A water treatment system includes: a housing assembly having a water inlet; a cover assembly disposed on the housing assembly, the cover assembly and the housing assembly enclosing a receiving cavity, the cover assembly having a water outlet; a filter assembly disposed on the housing assembly, the filter assembly extending along the height direction of the housing assembly, the filter assembly dividing the receiving cavity into a first chamber and a second chamber, the water inlet, the first chamber, the filter assembly and the second chamber being sequentially connected; and an inner tank assembly disposed on the inner tank assembly, the water outlet being connected to the second chamber and the inner tank assembly.

[0005] The first aspect of this application discloses a water treatment system that replaces the water softener in the traditional dishwasher's water circuit with a combination design of a cabinet assembly, a filter assembly, and a cover assembly. This eliminates the need for inputting and discharging high-concentration brine, making it more environmentally friendly and preventing corrosion of the dishwasher's internal metal parts. Furthermore, it eliminates the need for additional tap water to drain the brine, avoiding water waste. The filter assembly is located between the first and second chambers, ensuring that water in the first chamber is filtered before being transported to the second chamber, preventing scale buildup during subsequent heating. The inner tank assembly includes an inner tank and a water cup assembly. A water outlet directly connected to the inner tank assembly is provided through the cover assembly, allowing water to be directly transported from the inner tank assembly to the water cup assembly, saving on piping between the cabinet assembly and the water cup assembly, thus reducing costs.

[0006] In one embodiment, there are multiple water outlets, all of which are used to communicate with the inner liner assembly. By having multiple water outlets all connected to the second chamber and serving as communication points with the inner liner assembly, water delivery efficiency is improved. Integrating multiple water outlets into the cover assembly eliminates the need for additional branch pipes, simplifying the structure and reducing costs.

[0007] In one embodiment, the outlet extends along the height of the housing assembly. By extending the outlet along the height of the housing assembly, the water flow path from the second chamber to the inner liner assembly is shortened, thereby improving the water delivery efficiency.

[0008] In one embodiment, an inner liner assembly is also included. The housing assembly is disposed on the bottom wall of the inner liner assembly, and the bottom wall of the inner liner assembly has a flow-through cavity that communicates with the water outlet. Through the flow-through cavity of the inner liner assembly communicating with the water outlet, water can be directly transported from the second chamber into the flow-through cavity of the inner liner assembly, and then transported to the water cup assembly through the flow-through cavity, saving on the piping between the housing assembly and the water cup assembly, thus reducing costs.

[0009] In one embodiment, the system further includes an inlet valve and a breather. The inlet valve, the breather, and the inlet interface of the housing assembly are sequentially connected via pipes. The inner liner assembly includes a water cup assembly with a liquid storage chamber that communicates with the flow passage chamber. The inlet valve is connected to the inlet interface of the housing assembly via a pipe, enabling precise control of the water flow input and preventing excessive water intake or pressure fluctuations from affecting the filtration effect. The breather allows for adjustment of the internal air pressure of the system. The liquid storage chamber of the water cup assembly is connected to the flow passage chamber of the inner liner assembly, forming a continuous water flow path. Water can be directly transported from the second chamber to the flow passage chamber of the inner liner assembly, and then through the flow passage chamber to the water cup assembly, saving on the piping between the housing assembly and the water cup assembly, thus reducing costs.

[0010] In one embodiment, the cover assembly is located within the flow cavity. By positioning the cover assembly within the flow cavity, liquid output from the outlet on the cover assembly can be directly delivered into the flow cavity, preventing leakage during the process of liquid being transported from the second chamber into the flow cavity.

[0011] In one embodiment, a first protrusion is formed on the housing assembly, the first protrusion being located within the flow cavity. The assembly also includes a fixing member disposed on the housing assembly and / or the inner liner assembly, located between the first protrusion and the inner liner assembly, and surrounding the housing assembly. By positioning the fixing member between the first protrusion and the inner liner assembly, the connection strength between the housing assembly and the inner liner assembly is improved, enhancing the stability and reliability of the connection and preventing loosening due to water flow impact or vibration. In some applications, the fixing member is a nut.

[0012] In one embodiment, a second protrusion is formed on the housing assembly, the second protrusion being located outside the inner liner assembly. A seal is also included, disposed on the inner liner assembly and / or the housing assembly, located between the inner liner assembly and the second protrusion, and used to seal the gap between the inner liner assembly and the second protrusion. By positioning the seal between the inner liner assembly and the second protrusion, leakage of liquid from the first and second chambers through the gap between the inner liner assembly and the housing assembly is prevented, reducing water resource consumption.

[0013] In one embodiment, the cover assembly is detachably mounted on the housing assembly. Because the cover assembly is detachably mounted on the housing assembly, if the filter assembly loses its filtering effect due to clogging or other factors, the cover assembly can be opened to replace the filter assembly, thus maintaining its filtering effect. Directly replacing the filter assembly, instead of the traditional method of introducing brine into the resin chamber to restore water treatment efficiency, is more environmentally friendly.

[0014] In one embodiment, one of the cover assembly and the housing assembly is provided with a first snap-fit ​​portion, and the other of the cover assembly and the housing assembly is provided with a first locking groove, wherein the first snap-fit ​​portion is adapted to the first locking groove. This adaptation design of the first snap-fit ​​portion and the first locking groove enables rapid positioning and locking of the cover assembly and the housing assembly, significantly improving assembly and disassembly efficiency and increasing the efficiency of replacing the filter assembly.

[0015] In one embodiment, one of the cover assembly and the housing assembly is provided with a second snap-fit ​​portion, and the other of the cover assembly and the housing assembly is provided with a second locking groove, wherein the second snap-fit ​​portion is adapted to the second locking groove. The adaptation of the first snap-fit ​​portion to the first locking groove and the second snap-fit ​​portion to the second locking groove enables rapid positioning and locking of the cover assembly and the housing assembly, significantly improving assembly and disassembly efficiency and increasing the efficiency of filter component replacement. The mechanical interlocking characteristic of the snap-fit ​​and locking groove enhances the stability and reliability of the cover assembly and the housing assembly.

[0016] In one embodiment, the housing assembly has a positioning side surface and a positioning bottom surface, which are connected and both abut against the filter assembly. The positioning side surface and positioning bottom surface abut against different sides of the filter assembly, ensuring accurate installation of the filter assembly within the housing assembly and preventing offset or tilting. The close fit between the filter assembly and the positioning side surface and the positioning bottom surface reduces swaying caused by water flow impact or vibration, improving the stability of the filter assembly.

[0017] In one embodiment, the positioning side is annular. By making the positioning side annular, it matches the shape of the filter assembly, ensuring a tight fit between the filter assembly and the positioning side, resulting in good stability of the filter assembly.

[0018] In one embodiment, the filter assembly has a filter side surface and a filter end surface. The filter side surface is connected to the filter end surface, the filter side surface abuts against the positioning side surface, and the filter end surface abuts against the positioning bottom surface. The cooperation between the filter side surface and the annular positioning side surface ensures the radial positioning of the filter assembly, and the cooperation between the filter end surface and the positioning bottom surface ensures the axial positioning of the filter assembly, thereby achieving precise fixation of the filter assembly in all directions.

[0019] In one embodiment, the housing assembly is provided with a pressure relief channel, and the water inlet, the pressure relief channel, and the second chamber are sequentially connected. It also includes a sealing component disposed on the housing assembly and located at the pressure relief channel. The sealing component can block or open the pressure relief channel. By blocking or opening the pressure relief channel through the sealing component, when the filter element is clogged and the water flow is blocked, the pressure relief channel automatically opens, allowing water to bypass the first chamber and directly enter the second chamber, preventing excessive hydraulic pressure that could cause malfunctions in the housing assembly or filter assembly.

[0020] In one embodiment, the pressure relief channel includes a first notch, a flow channel, and a second notch. The water inlet, the first notch, the flow channel, the second notch, and the second chamber are sequentially connected. The sealing component can either block or allow the first notch to open. By sealing the first notch, the pressure relief water path can be blocked; if the first notch is not blocked, the pressure relief water path remains open. Since the cross-sectional area of ​​the first notch is smaller than that of the flow channel, this method makes it simpler and more convenient to achieve both opening and blocking of the pressure relief water path, resulting in a better sealing effect.

[0021] In one embodiment, the housing assembly is provided with a water inlet channel and a water inlet, the water inlet being located at the bottom of the housing assembly. The water inlet, the water inlet channel, the water inlet, and the first chamber are sequentially connected, and the pressure relief channel is connected to the water inlet channel. The sequential connection of the water inlet channel, the water inlet, the water inlet, and the first chamber allows for a continuous supply of water to the first chamber.

[0022] A dishwasher includes: the water treatment system described above.

[0023] The second aspect of this application discloses a dishwasher that replaces the water softener in the water circuit of a traditional dishwasher with a combination design of a cabinet assembly, a filter assembly, and a lid assembly, reducing the consumption of brine and additional tap water. The filter assembly effectively prevents scale from entering the heating element, avoiding scale formation and extending the lifespan of the dishwasher's heating element. The water outlet on the lid assembly directly connects to the inner tank assembly, and the inner tank assembly connects to the water cup assembly, allowing water to flow directly from the inner tank assembly to the water cup assembly, reducing the connecting pipes between the water outlet and the water cup assembly.

[0047] The first aspect of this application discloses a water treatment system that replaces the water softener in the traditional dishwasher water circuit with a combination design of a housing assembly 1, a filter assembly 2, and a cover assembly 3. Therefore, it eliminates the need for inputting and discharging high-concentration brine, making it more environmentally friendly and preventing corrosion of the dishwasher's internal metal parts. Furthermore, it eliminates the need for additional tap water to drain the brine, avoiding water waste. The filter assembly 2 is located between the first chamber 103 and the second chamber 104, ensuring that the water in the first chamber 103 is filtered before being transported to the second chamber 104, preventing scale formation during subsequent heating.

[0051] like Figure 1-3 As shown, in addition to the features of the above embodiments, this embodiment further includes: a water inlet valve 6 and a breather 7. The water inlet valve 6, the breather 7, and the water inlet interface 101 of the housing assembly 1 are sequentially connected by pipes. The inner liner assembly 5 is provided with a water cup assembly 8, and the water cup assembly 8 is provided with a liquid storage chamber 801, which is connected to the flow passage chamber 501. The water inlet valve 6 is connected to the water inlet interface 101 of the housing assembly 1 through a pipe to achieve precise control of water flow input and avoid excessive water intake or pressure fluctuations affecting the filtration effect. The breather 7 can adjust the internal air pressure of the system. The liquid storage chamber 801 of the water cup assembly 8 is connected to the flow passage chamber 501 of the inner liner assembly 5 to form a continuous water flow path. Water can be directly transported from the second chamber 104 to the flow passage chamber 501 of the inner liner assembly 5, and then transported to the water cup assembly 8 through the flow passage chamber 501, saving the pipeline from the housing assembly 1 to the water cup assembly 8 and reducing costs.

[0052] like Figure 1 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cover assembly 3 is located within the flow cavity 501. Because the cover assembly 3 is located within the flow cavity 501, liquid output from the outlet 301 on the cover assembly 3 can be directly transported into the flow cavity 501, preventing leakage of liquid during the process of being transported from the second chamber 104 into the flow cavity 501.

[0053] like Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first protrusion 11 is formed on the housing assembly 1, the first protrusion 11 is located within the flow cavity 501, and a fixing member 9 is also included. The fixing member 9 is disposed on the housing assembly 1 and / or the inner liner assembly 5, the fixing member 9 is located between the first protrusion 11 and the inner liner assembly 5, and the fixing member 9 is arranged around the housing assembly 1. By fixing the member 9 between the first protrusion 11 and the inner liner assembly 5, the connection strength between the housing assembly 1 and the inner liner assembly 5 is improved, the stability and reliability of the connection between the housing assembly 1 and the inner liner assembly 5 are enhanced, and loosening due to water flow impact or vibration is prevented. In some application scenarios, the fixing member 9 is a nut.

[0055] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the cover assembly 3 is detachably mounted on the housing assembly 1. Because the cover assembly 3 is detachably mounted on the housing assembly 1, if the filter assembly 2 loses its filtering effect due to clogging or other factors, the cover assembly 3 can be opened to replace the filter assembly 2, thus maintaining the filtering effect of the filter assembly 2. Directly replacing the filter assembly 2 replaces the traditional method of introducing brine into the resin chamber to restore the water treatment effect, which is more environmentally friendly.

[0056] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: one of the cover assembly 3 and the box assembly 1 is provided with a first snap-fit ​​part 13, and the other of the cover assembly 3 and the box assembly 1 is provided with a first slot 302, wherein the first snap-fit ​​part 13 is adapted to the first slot 302.

The mechanical interlocking characteristics of the snap-fit ​​and the slot enhance the stability and reliability of the cover assembly 3 and the box assembly 1.

[0058] like Figure 5 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a positioning side surface 106 and a positioning bottom surface 107, the positioning side surface 106 and the positioning bottom surface 107 are connected, and both the positioning side surface 106 and the positioning bottom surface 107 abut against the filter assembly 2. The positioning side surface 106 and the positioning bottom surface 107 of the housing assembly 1 abut against different sides of the filter assembly 2 to ensure that the filter assembly 2 is accurately installed in the housing assembly 1 and to avoid offset or tilting. The filter assembly 2 is in close contact with the positioning side surface 106 and the positioning bottom surface 107 to reduce shaking caused by water flow impact or vibration and improve the stability of the filter assembly 2.

[0059] In addition to the features of the above embodiments, this embodiment further specifies that the positioning side 106 is annular. By making the positioning side 106 annular, it matches the shape of the filter assembly 2, ensuring a tight fit between the filter assembly 2 and the positioning side 106, resulting in good stability of the filter assembly 2.

[0060] like Figure 5 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a filter side surface 201 and a filter end surface 202 are formed on the filter assembly 2, the filter side surface 201 is connected to the filter end surface 202, the filter side surface 201 abuts against the positioning side surface 106, and the filter end surface 202 abuts against the positioning bottom surface 107.

By sealing the first notch 1021 with the sealing component 4, the pressure relief water path can be blocked; if the first notch 1021 is not blocked, the pressure relief water path is open. Since the cross-sectional area of ​​the first notch 1021 is smaller than that of the flow channel 1022, this method makes it simpler and more convenient to achieve both opening and blocking of the pressure relief water path, and the sealing effect is better.

[0063] like Figure 5 As shown, the housing assembly 1 is provided with a water inlet channel 108 and a water inlet 109. The water inlet 109 is located at the bottom of the housing assembly 1.
