Description

Technical Field

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

[0002] Dishwashers typically include a breather and a water softener. The breather balances air pressure, while the water softener reduces water hardness. A water softener usually involves two processes: softening and regeneration. The softening process occurs when hard water flows through a resin used to soften the water. Sodium ions on the resin surface replace calcium and magnesium ions in the water, producing softened water for washing. The regeneration process involves injecting a high-concentration brine solution. Sodium ions displace the calcium and magnesium ions adsorbed in the resin, and the brine is discharged with the wastewater. The resin is then rinsed with tap water to remove excess brine, restoring its softening capacity. However, this device has the following drawbacks: the water softener requires a brine chamber and a resin chamber, and the large volume of these chambers occupies limited space in the dishwasher, hindering the addition of other functional components. Utility Model Content

[0003] Therefore, it is necessary to provide a water treatment device and a dishwasher to address the problem that water softeners need to include a brine chamber and a resin chamber, and the brine chamber and resin chamber have large volumes, which occupy the limited space of the dishwasher and thus make it difficult to add other functional components to the dishwasher.

[0004] A water treatment device includes: an inner tank assembly having a washing chamber and a material replacement hole on its side wall, the material replacement hole communicating with the washing chamber; a water cup assembly disposed on the inner tank assembly and having a water cup inlet; and a scale inhibitor disposed at the material replacement hole, the scale inhibitor having a scale inhibitor material accommodating space communicating with either the material replacement hole or the water cup inlet.

[0005] The first aspect of this application discloses a water treatment device that can store materials for water treatment, such as resin or other scale inhibitors, through a scale inhibitor material accommodating space. This design replaces the original resin chamber and salt chamber of the water softener with the scale inhibitor material accommodating space, resulting in a smaller overall size. The scale inhibitor component can be installed on the side wall of the inner tank assembly, effectively saving bottom space and facilitating the addition of other functional components. By installing the scale inhibitor component on the material replacement hole, when the scale inhibitor material fails, the resin in the scale inhibitor material accommodating space can be directly replaced through the material replacement hole of the inner tank assembly, thus eliminating the need for a regeneration process. This design eliminates the need to discharge brine, making it more environmentally friendly and preventing corrosion of the metal parts inside the dishwasher. Furthermore, it eliminates the need to use tap water to rinse the resin to restore its softening ability, thus reducing water waste and shortening the overall washing cycle time. The scale inhibitor material accommodating space is connected to the material replacement hole or the water cup inlet, allowing water treated by the scale inhibitor material to be supplied to either the inner tank assembly or the water cup assembly.

[0006] In one embodiment, the water cup assembly is provided with a water cup liquid storage cavity, which is connected to the water cup inlet and the washing cavity.

[0007] In one embodiment, the inner liner assembly has a mounting hole communicating with the washing chamber. The breather has an air inlet communicating with the washing chamber, with the portion of the breather containing the air inlet located at the mounting hole. The breather also has a breathing chamber communicating with the air inlet. A one-way valve is also included, disposed on the breather and located between the breathing chamber and the water inlet channel. The mounting hole provides mounting positioning for the breather, allowing it to be assembled in the correct position. The air inlet and breathing chamber of the breather help balance the air pressure in the inner liner assembly, preventing malfunctions caused by excessive air pressure. The one-way valve located between the breathing chamber and the water inlet channel ensures unidirectional flow, preventing siphoning.

[0008] In one embodiment, a flow meter is also included, which is disposed on the breather, and the water inlet channel flows through the flow meter. The flow meter accurately measures the water flow rate entering the scale inhibitor containment space, ensuring the water flow rate is within the optimal range.

[0009] In one embodiment, a connecting pipe is further included, which is connected to both the water cup assembly and the scale inhibitor. The scale inhibitor accommodating space, the connecting pipe, and the water cup inlet are sequentially connected. By connecting the connecting pipe to both the water cup assembly and the scale inhibitor, the scale inhibitor can be directly mounted on the inner tank assembly. The liquid output from the scale inhibitor can be directly transferred to the washing chamber or directly to the interior of the water cup assembly.

[0010] In one embodiment, a breather is also included, which is disposed on the inner tank assembly. The breather has a breather inlet and an inlet channel, and the breather inlet, the inlet channel, and the scale-inhibiting material receiving space are sequentially connected. Alternatively, the scale-inhibiting component can be disposed separately on the inner tank assembly, or it can be disposed on the breather, with both the scale-inhibiting component and the breather being disposed together on the inner tank assembly. By integrating the scale-inhibiting component onto the breather, the traditional resin water softener is eliminated, resulting in a simpler structure, fewer parts, and lower cost. This integrated design allows a single device to simultaneously achieve pressure balancing and water treatment functions, effectively saving space at the bottom of the dishwasher and facilitating the installation of more functional components.

[0011] In one embodiment, the scale inhibitor is integrally formed with or detachably connected to the respirator.

[0012] In one embodiment, the scale inhibitor includes a support portion and a soft water portion. The support portion is disposed on the breather, and the soft water portion is disposed on the support portion. The soft water portion is located at the material replacement hole and has a space for receiving the scale inhibitor material. The support portion provides stable support for the soft water portion. Furthermore, it provides an installation spacing for the corresponding assembly of the breather and the soft water portion, allowing them to be assembled in the corresponding holes.

[0013] In one embodiment, the breather has a water outlet channel and a breather outlet. The water inlet channel, the scale inhibitor accommodating space, the water outlet channel, and the breather outlet are sequentially connected. The breather outlet is connected to the water cup inlet. Through the sequential connection of the water inlet channel, scale inhibitor, water outlet channel, breather outlet, and water cup inlet, hard water, after being treated by the scale inhibitor in the scale inhibitor accommodating space, can be smoothly delivered to the water cup assembly, providing a continuous supply of soft water for subsequent cleaning operations. This water treatment reduces the adhesion of scale to the surface of the heating appliance, effectively improving the heating efficiency and service life of the heating appliance.

[0014] In one embodiment, the water outlet channel and the water inlet channel are arranged adjacent to each other. By arranging the water outlet channel and the water inlet channel adjacent to each other, the distribution of the water inlet channel and the water outlet channel within the respirator is more compact, which can effectively reduce the size of the respirator, effectively save space in the inner liner assembly, and facilitate the addition of other functional components.

[0015] In one embodiment, the respirator assembly is provided with a separating rib to separate the water inlet channel and the water outlet channel. By using the separating rib to separate the water inlet and outlet channels, the flow in the water inlet and outlet channels does not interfere with each other, allowing the water to be discharged in an orderly manner after softening treatment. Furthermore, the water inlet and outlet channels are separated only by a relatively thin separating rib, making their distribution more compact and effectively reducing the size of the respirator.

[0016] In one embodiment, the outlet of the breather and the inlet of the water cup are connected by a pipe. This connection allows hard water to be smoothly delivered to the water cup assembly after being treated by the scale-inhibiting material in the scale-inhibiting material's containment space, providing a continuous supply of soft water for subsequent cleaning operations.

[0017] In one embodiment, a cover is also included, which is detachably mounted on the scale inhibitor. The cover covers the end of the scale inhibitor material receiving space, sealing the scale inhibitor material receiving space. The water inlet channel, the scale inhibitor material receiving space, and the water cup inlet are sequentially connected. Because the cover is detachably mounted on the scale inhibitor, it can be removed at the material replacement hole for replacement of the scale inhibitor material. This design eliminates the need to discharge brine, making it more environmentally friendly and preventing corrosion of the metal parts inside the dishwasher. Furthermore, it eliminates the need to use tap water to rinse the resin to restore its soft water capacity, thus reducing water waste and shortening the overall washing cycle time.

[0018] In one embodiment, the water softening unit is provided with a scale-inhibiting inlet and a scale-inhibiting outlet. The scale-inhibiting inlet is connected to the water inlet channel, and the scale-inhibiting inlet, the scale-inhibiting material accommodating space, and the scale-inhibiting outlet are sequentially connected. The scale-inhibiting outlet is connected to the material replacement hole. The treated water can be directly transported from the scale-inhibiting component into the washing chamber, and can be used directly or stored in the water cup assembly through the washing chamber.

[0019] In one embodiment, the scale inhibitor containing space has an arc-shaped cross-section. The scale inhibitor inlet is located at the first end of the arc-shaped space, and the scale inhibitor outlet is located at or near the second end of the arc-shaped space. This design, with the scale inhibitor containing space having an arc-shaped cross-section and the outlet located at or near the second end, is more rational. The water path within the scale inhibitor containing space is longer, allowing for a longer treatment time for hard water, thus resulting in better hard water treatment performance.

[0020] In one embodiment, a cover is further included, which is detachably mounted on the scale inhibitor. The cover covers the end of the scale inhibitor material receiving space and has an opening. The water inlet channel, the scale inhibitor material receiving space, the cover opening, and the washing chamber are sequentially connected. Because the cover is detachably mounted on the scale inhibitor, it can be removed and replaced at the material replacement hole when the scale inhibitor material needs to be replaced. This design eliminates the need to discharge brine, making it more environmentally friendly and preventing corrosion of the metal parts inside the dishwasher. Furthermore, it eliminates the need to use tap water to rinse the resin to restore its soft water capacity, thus reducing water waste and shortening the overall washing cycle time.

[0021] In one embodiment, a respirator is also included, which is disposed on the inner liner assembly. The respirator has an infusion channel that communicates with the water inlet of the water cup. It also includes an inlet valve, with the input end of the scale inhibitor communicating with the inlet valve and the output end of the scale inhibitor communicating with the infusion channel. The scale inhibitor can also be disposed at the front end of the respirator's water path, achieving the same function.

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

[0023] The second aspect of this application discloses a dishwasher that integrates water treatment and air pressure balancing functions into one device or replaces the traditional resin chamber and salt chamber with a scale-inhibiting material, making the overall layout of the dishwasher more compact. This effectively reduces the space at the bottom of the dishwasher, facilitating the addition of other functional modules. Furthermore, materials can be replaced at the material replacement hole, making it more environmentally friendly and water-saving. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] Example 1

[0045] like Figure 1 and Figure 5As shown, this embodiment discloses a water treatment device, including: an inner tank assembly 1, the inner tank assembly 1 having a washing chamber 101, and a material replacement hole 102 on the side wall of the inner tank assembly 1, the material replacement hole 102 communicating with the washing chamber 101; a water cup assembly 3, the water cup assembly 3 being disposed on the inner tank assembly 1 and having a water cup inlet 301; and a scale inhibitor 2, the scale inhibitor 2 being disposed at the material replacement hole 102, the scale inhibitor 2 having a scale inhibitor material accommodating space 201, the scale inhibitor material accommodating space 201 communicating with the material replacement hole 102 or the water cup inlet 301.

[0046] The first aspect of this application discloses a water treatment device that can store materials for water treatment, such as resin or other scale inhibitors, through a scale inhibitor material accommodating space 201. This design replaces the original resin chamber and salt chamber of the water softener with the scale inhibitor material accommodating space 201, resulting in a smaller overall size. The scale inhibitor component 2 can be installed on the side wall of the inner tank assembly 1, effectively saving bottom space and facilitating the addition of other functional components. By installing the scale inhibitor component 2 on the material replacement hole 102, when the scale inhibitor material fails, the resin in the scale inhibitor material accommodating space 201 can be directly replaced through the material replacement hole 102 of the inner tank assembly 1, thus eliminating the need for a regeneration process. This design eliminates the need to discharge brine, making it more environmentally friendly and preventing corrosion of the metal parts inside the dishwasher. Furthermore, it eliminates the need to use tap water to rinse the resin to restore its softening ability, thus reducing water waste and shortening the overall washing cycle time. The scale inhibitor material receiving space 201 is connected to the material replacement hole 102 or the water cup inlet 301. Water treated by the scale inhibitor material can be supplied to the inner tank assembly 1 or the water cup assembly 3.

[0047] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water cup assembly 3 is provided with a water cup liquid storage cavity 302, the water cup liquid storage cavity 302 is connected to the water cup inlet 301, and the water cup liquid storage cavity 302 is connected to the washing cavity 101.

[0048] like Figure 1 , Figure 7 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner liner assembly 1 is provided with a mounting hole 103, the mounting hole 103 communicates with the washing chamber 101, the breather 4 is provided with an air inlet communicating with the washing chamber 101, the portion of the breather 4 with the air inlet is located at the mounting hole 103, the breather 4 is provided with a breathing chamber communicating with the air inlet, and also includes a one-way valve 6, the one-way valve 6 is disposed on the breather 4, the one-way valve 6 is located between the breathing chamber and the water inlet channel 401. The mounting hole 103 provides installation positioning for the breather 4, allowing the breather 4 to be assembled in the corresponding position. The air inlet and breathing chamber of the breather 4 can balance the air pressure of the inner liner assembly 1, avoiding malfunctions caused by excessive air pressure. The one-way valve 6 located between the breathing chamber and the water inlet channel 401 ensures unidirectional flow, avoiding siphoning.

[0049] like Figure 3 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further includes a flow meter 7, which is disposed on the breather 4, and the water inlet channel 401 flows through the flow meter 7. The flow meter 7 accurately measures the water flow rate entering the scale inhibitor containing space 201, ensuring that the water flow rate is within the optimal range.

[0050] Example 2

[0051] It also includes connecting pipes, which are connected to the water cup assembly 3 and the scale inhibitor 2, respectively. The scale inhibitor material receiving space 201, the connecting pipes, and the water cup inlet 301 are sequentially connected. The scale inhibitor 2 can be directly mounted on the inner tank assembly 1, and the liquid output from the scale inhibitor 2 can be directly transferred into the washing chamber 101 or directly into the interior of the water cup assembly 3.

[0052] Example 3

[0053] like Figure 3 and Figure 7As shown, the device also includes a breather 4, which is mounted on the inner tank assembly 1. The breather 4 has a breather inlet 404 and an inlet channel 401. The breather inlet 404, the inlet channel 401, and the scale-inhibiting material receiving space 201 are sequentially connected. Alternatively, the scale-inhibiting component 2 can be mounted separately on the inner tank assembly 1, or it can be mounted on the breather 4, with both components mounted together on the inner tank assembly 1. By integrating the scale-inhibiting component 2 onto the breather 4, the traditional resin water softener is eliminated, resulting in a simpler structure, fewer parts, and lower cost. This integrated design allows a single device to simultaneously achieve pressure balancing and water treatment functions, effectively saving bottom space in the dishwasher and facilitating the installation of more functional components.

[0054] like Figure 3 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the scale inhibitor 2 is integrally formed with the respirator 4 or is detachably connected.

[0055] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the scale inhibitor 2 includes a support portion 21 and a water softener portion 22. The support portion 21 is disposed on the breather 4, and the water softener portion 22 is disposed on the support portion 21. The water softener portion 22 is located at the material replacement hole 102, and the water softener portion 22 has a scale inhibitor material receiving space 201. The configuration of the support portion 21 provides stable support for the water softener portion 22. Furthermore, it provides an installation spacing for the corresponding assembly of the breather 4 and the water softener portion 22, allowing the breather 4 and the water softener portion 22 to be assembled in the corresponding holes.

[0056] Example 4

[0057] like Figure 5 and Figure 7 As shown, the breather 4 is equipped with a water outlet channel 402 and a breather outlet 403. The water inlet channel 401, the scale inhibitor accommodating space 201, the water outlet channel 402, and the breather outlet 403 are sequentially connected. The breather outlet 403 is connected to the water cup inlet 301. Through the sequential connection of the water inlet channel 401, scale inhibitor 2, water outlet channel 402, breather outlet 403, and water cup inlet 301, hard water, after being treated by the scale inhibitor in the scale inhibitor accommodating space 201, can be smoothly delivered to the water cup assembly 3, providing a continuous supply of soft water for subsequent cleaning operations. Water treatment can reduce the phenomenon of scale adhering to the surface of the heating appliance, effectively improving the heating efficiency and service life of the heating appliance.

[0058] like Figure 5 and Figure 7-8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the water outlet channel 402 and the water inlet channel 401 are arranged adjacent to each other. By arranging the water outlet channel 402 and the water inlet channel 401 adjacent to each other, the distribution of the water inlet channel 401 and the water outlet channel 402 within the respirator 4 is more compact, which can effectively reduce the volume of the respirator 4, effectively save space in the inner liner assembly 1, and facilitate the addition of other functional components.

[0059] like Figure 5 and Figure 7-8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the respirator 4 assembly is provided with an isolation rib 41, which is used to separate the water inlet channel 401 and the water outlet channel 402. By using the isolation rib 41 to separate the water inlet channel 401 and the water outlet channel 402, the flow of the water inlet channel 401 and the water outlet channel 402 does not interfere with each other, allowing the water to be output in an orderly manner after softening treatment. Moreover, the water inlet channel 401 and the water outlet channel 402 are separated only by a relatively thin isolation rib 41, making the distribution of the water inlet channel 401 and the water outlet channel 402 more compact, effectively reducing the volume of the respirator 4.

[0060] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the respirator outlet 403 and the water cup inlet 301 are connected by a pipe. Because the respirator outlet 403 and the water cup inlet 301 are connected by a pipe, hard water, after being treated by the scale-inhibiting material in the scale-inhibiting material accommodating space 201, can be smoothly delivered to the water cup assembly 3, providing a continuous supply of soft water for subsequent cleaning operations.

[0061] In addition to the features of the above embodiments, this embodiment further includes a cover, which is detachably mounted on the scale inhibitor 2. The cover covers the end of the scale inhibitor material receiving space 201, sealing the scale inhibitor material receiving space 201. The water inlet channel 401, the scale inhibitor material receiving space 201, and the water cup inlet 301 are sequentially connected. Because the cover is detachably mounted on the scale inhibitor 2, it can be removed and replaced at the material replacement hole 102 when the scale inhibitor material needs to be replaced. This design eliminates the need to discharge brine, making it more environmentally friendly and preventing corrosion of the metal parts inside the dishwasher. Furthermore, it eliminates the need to use tap water to rinse the resin to restore its soft water capacity, thus reducing water waste and shortening the overall washing cycle time.

[0062] Example 5

[0063] like Figure 1-4As shown, the soft water section 22 is provided with a scale-inhibiting inlet 203 and a scale-inhibiting outlet 202. The scale-inhibiting inlet 203 is connected to the water inlet channel 401. The scale-inhibiting inlet 203, the scale-inhibiting material receiving space 201, and the scale-inhibiting outlet 202 are connected in sequence. The scale-inhibiting outlet 202 is connected to the material replacement hole 102. The treated water can be directly transported from the scale-inhibiting component 2 to the washing chamber 101, and can be used directly or stored in the water cup assembly 3 through the washing chamber 101.

[0064] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the cross-section of the scale inhibitor material receiving space 201 is arc-shaped, the scale inhibitor inlet 203 is located at the first end of the arc-shaped scale inhibitor material receiving space 201, and the scale inhibitor outlet 202 is located at or near the second end of the arc-shaped scale inhibitor material receiving space 201. By having the scale inhibitor material receiving space 201 have an arc-shaped cross-section and the scale inhibitor outlet 202 is located at or near the second end of the scale inhibitor material receiving space 201, the design is more reasonable, the water path of the scale inhibitor material receiving space 201 is longer, the hard water treatment time is longer, and thus the hard water treatment effect is better.

[0065] In addition to the features of the above embodiments, this embodiment further includes a cover, which is detachably mounted on the scale inhibitor 2. The cover covers the end of the scale inhibitor material receiving space 201, and the cover has an opening. The water inlet channel 401, the scale inhibitor material receiving space 201, the cover opening, and the washing chamber 101 are sequentially connected. Because the cover is detachably mounted on the scale inhibitor 2, the cover can be removed and replaced at the material replacement hole 102 when the scale inhibitor material needs to be replaced. This design eliminates the need to discharge brine, making it more environmentally friendly and preventing corrosion of the metal parts inside the dishwasher. Furthermore, it eliminates the need to use tap water to rinse the resin to restore its soft water capacity, thus reducing water waste and shortening the overall washing cycle time.

[0066] Example 6

[0067] The system also includes a breather 4, which is mounted on the inner liner assembly 1. The breather 4 has an infusion channel that communicates with the water inlet 301 of the water cup. It also includes an inlet valve 5, with the input end of the scale inhibitor 2 connected to the inlet valve 5 and the output end connected to the infusion channel. The scale inhibitor 2 can also be located at the front end of the water path of the breather 4, achieving the same function.

This makes the overall layout of the dishwasher more compact, effectively reducing the space at the bottom of the dishwasher and facilitating the addition of other functional modules. Furthermore, materials can be replaced at the material replacement hole 102, making it more environmentally friendly and water-saving.

[0071] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
