Description

Technical Field

[0001] This invention belongs to the field of kitchen appliances, and more specifically, relates to a breather for a dishwasher and a dishwasher. Background Technology

[0002] Dishwashers are kitchen appliances used to automatically clean dishes, chopsticks, plates, dishes, knives, forks and other tableware. As people's living standards continue to improve and their requirements for quality of life increase, dishwashers are gradually being accepted and recognized by the public and are entering the kitchens of thousands of households.

[0003] Dishwashers consist of a connected washing chamber and a water softener. The water softener supplies water to the washing chamber to clean the dishes placed inside. The water softener includes a resin chamber and a salt chamber. It uses cation exchange resin to remove calcium and magnesium ions from the water, reducing the hardness of the washing water and softening it to prevent carbonate scale buildup in the washing chamber. The cation exchange resin regeneration process usually occurs after the washing cycle. Water is introduced into the salt chamber to form a concentrated brine, which is then introduced into the resin chamber to exchange calcium and magnesium ions in the cation exchange resin, restoring the resin's ability to soften the washing water. However, this method of supplying water to the salt chamber results in a large water flow rate, consuming a lot of salt and water, leading to water waste.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a breather for a dishwasher to achieve a more water-efficient water supply to the brine chamber.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A breather for a dishwasher, the breather having a first flow channel and a second flow channel, the outlet of the first flow channel being connected to the resin chamber of the softener of the dishwasher, the outlet of the second flow channel being connected to the salt chamber of the softener of the dishwasher, and an anti-siphon structure being provided between the first flow channel and the second flow channel, through which water enters the second flow channel.

[0008] Furthermore, the dishwasher also includes a washing chamber, the breather has a connecting port that communicates with the washing chamber, and the second flow channel includes a first branch and a second branch. The first branch is located above the connecting port and communicates with the washing chamber, the second branch is located on one side of the connecting port, and the water inlet of the second branch is communicated with the water outlet of the first branch.

[0009] The first flow channel is connected to the first branch via an anti-siphon structure, and the outlet of the second branch is connected to the brine chamber.

[0010] Furthermore, the second branch is equipped with a diversion guide rib extending from one side wall of the waterway to the opposite side, and there is a gap between the extended end of the diversion guide rib and the side wall of the waterway for water flow.

[0011] Preferably, one end of the diversion guide rib is connected to the side wall of the second branch near the connection port.

[0012] Furthermore, a drain outlet is provided on the side wall of the second branch near the outer periphery of the connecting port. The drain outlet is located below the diversion guide rib, and the salt chamber is connected to the washing chamber through the drain outlet.

[0013] Furthermore, the second branch includes a bent flow channel section, a protruding flow channel section, and a rotating flow channel section. The upper end of the bent flow channel section is connected to the outlet of the first branch, and the lower end of the bent flow channel section is connected to the upper end of the protruding flow channel section. The protruding flow channel section protrudes axially from the first flow channel, and an overflow outlet connected to the upper end of the rotating flow channel section is provided on the side wall of the protruding flow channel section away from the outer periphery of the connecting port. The lower end of the rotating flow channel section is provided with an outlet connected to the brine chamber.

[0014] Furthermore, an inner wall is provided between the first branch and the first flow channel, and an anti-siphon structure is provided on the inner wall. The lower end of the inner wall is connected to the upper end of the side wall of the bent flow channel section away from the outer periphery of the connecting opening.

[0015] Furthermore, the protruding flow channel section includes a first sidewall close to the outer periphery of the connecting port and a second sidewall away from the outer periphery of the connecting port. The first sidewall is provided with a diversion guide rib extending to the second sidewall, and there is a gap between the extended end of the diversion guide rib and the second sidewall for water to flow through.

[0016] An overflow outlet connected to the rotary flow channel section is provided on the second side wall, and a drain outlet connected to the washing chamber is provided on the first side wall. The overflow outlet and the drain outlet are respectively located below the diversion guide rib.

[0017] Furthermore, it also includes an air channel connecting the salt chamber, with the rotary channel section and the air channel arranged side by side, and a partition rib between the rotary channel section and the air channel. The air outlet of the air channel is higher than the drain outlet.

[0018] Furthermore, there is a gap between the bottom wall of the protruding flow channel section and the bottom wall of the first flow channel for the water in the first flow channel to pass through.

[0019] Another object of the present invention is to provide a dishwasher that avoids water waste and improves the dishwasher's working capacity.

[0020] The present invention also provides a dishwasher, including any of the above-described breather for dishwashers.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0022] 1. In this invention, an anti-siphon structure is provided between the first flow channel and the second flow channel. Water enters the second flow channel through the first flow channel via the anti-siphon structure, so that the water overflowing through the anti-siphon structure is used for the brine chamber water intake, avoiding water waste and preventing unsoftened water from entering the washing chamber, which would cause scale buildup inside the washing chamber and affect the service life of the dishwasher.

[0023] 2. In this invention, water is introduced into the salt chamber through the second flow channel. When the salt chamber is full, the excess water overflows from the overflow port into the protruding flow channel section and flows into the washing chamber through the drain port, thereby preventing the water overflowing from the salt chamber from leaking out through the air flow channel, which would waste water resources and affect the user experience.

[0036] Example 1

[0037] like Figures 1 to 4As shown, this embodiment of the invention provides a breather 100 for a dishwasher. The breather 100 has a first flow channel 1 and a second flow channel 2. The outlet of the first flow channel 1 is connected to the resin chamber of the softener of the dishwasher, and the outlet of the second flow channel 2 is connected to the salt chamber of the softener of the dishwasher. An anti-siphon structure 3 is provided between the first flow channel 1 and the second flow channel 2, and water enters the second flow channel 2 through the anti-siphon structure 3.

[0038] In the above scheme, an anti-siphon structure 3 is provided between the first flow channel 1 and the second flow channel 2. Water enters the second flow channel 2 through the first flow channel 1 via the anti-siphon structure 3, so that the water overflowing through the anti-siphon structure 3 is used for the salt chamber water intake, avoiding water waste and preventing unsoftened water from entering the washing chamber, which would cause scale buildup in the washing chamber and affect the service life of the dishwasher.

[0039] like Figure 1 and Figure 2 As shown in the example, the respirator 100 includes a housing 101, which has a first flow channel 1 and a second flow channel 2. The first flow channel 1 is provided with an inlet 11, the outlet of the first flow channel 1 is a first outlet 12, and the outlet of the second flow channel 2 is a second outlet 21.

[0040] like Figure 1 and Figure 2 As shown, the dishwasher also includes a washing chamber, the breather 100 has a connecting port 6 that communicates with the washing chamber, the second flow channel 2 includes a first branch 22 and a second branch 23, the first branch 22 is located above the connecting port 6 and communicates with the washing chamber, the second branch 23 is located on one side of the connecting port 6, the inlet 11 of the second branch 23 is communicated with the outlet of the first branch 22; the first flow channel 1 is communicated with the first branch 22 via the anti-siphon structure 3, and the outlet of the second branch 23 is communicated with the salt chamber.

[0041] In the above scheme, the second branch 23 is located slightly lower than the anti-siphon structure 3. The inlet 11 of the second branch 23 is located on the outer periphery of the connecting port 6. When the first flow channel 1 enters the resin chamber, some of the water in the first flow channel 1 flows into the first branch 22 through the anti-siphon structure 3, and then flows into the second branch 23 through the outlet of the first branch 22, and finally flows into the salt chamber below the respirator 100. This realizes that the second flow channel 2 enters the salt chamber, controls the water inlet of the salt chamber, and at the same time avoids unsoftened water from leaking into the washing chamber through the anti-siphon structure 3, which would cause scale to form in the washing chamber.

[0042] like Figure 3 and Figure 4 As shown, in this example, an inner wall 221 is provided between the first branch 22 and the first flow channel 1. The inner wall 221 is provided with an anti-siphon structure 3 for the first flow channel 1 to enter the first branch 22. The inner wall 221 bends downward and connects to the side wall of the second branch 23 on the side away from the connecting port 6.

[0043] In the above solution, the anti-siphon structure 3 is installed on the inner wall 221 between the first branch 22 and the first flow channel 1, so that the water flowing into the first branch 22 flows into the salt chamber through the second branch 23, avoiding the flow of unsoftened water into the washing chamber connected to the first branch 22, which would increase the hardness of the washing water in the washing chamber and cause scale buildup in the washing chamber, thus affecting the service life of the dishwasher.

[0044] like Figure 3 and Figure 4 As shown in this example, the second branch 23 is provided with a diversion guide rib 26 extending from one side wall of the water channel to the opposite side. There is a gap between the extension end of the diversion guide rib 26 and the side wall of the water channel for water to flow through. The water flow velocity and direction are adjusted by the diversion guide rib 26 to ensure that the water in the second branch 23 flows smoothly into the salt cavity and mixes fully with the sodium chloride in the salt cavity to form a uniform sodium chloride solution.

[0045] Preferably, one end of the diversion guide rib 26 is connected to the side wall of the second branch 23 near the connecting port 6, so as to guide the water flow out from the gap between the extension end of the diversion guide rib 26 and the side wall of the second branch 23 away from the connecting port 6.

[0046] More preferably, the extended end of the diversion guide rib 26 is inclined or bent in the downstream direction of the second branch 23 to further reduce the water flow velocity upstream of the second branch 23 and guide the water flow downward, ensuring that the water flowing into the salt cavity is fully mixed with the sodium chloride in the salt cavity, while avoiding excessive water flow and causing leakage in the salt cavity.

[0047] More preferably, the second branch 23 located below the diversion guide 26 protrudes in the direction of the diversion guide 26 and bends downward to ensure that the water flows more smoothly downward.

[0048] like Figure 3 and Figure 4 As shown in this example, a drain outlet 24 is provided on the side wall of the second branch 23 near the outer periphery of the connecting port 6. The drain outlet 24 is located below the diversion guide rib 26, and the salt chamber is connected to the washing chamber through the drain outlet 24.

[0049] In the above solution, water is introduced into the salt chamber through the second flow channel 2. When the salt chamber is full, the excess water will flow into the washing chamber from the drain outlet 24, thereby avoiding water leakage from the salt chamber, which would waste water resources, reduce the working capacity of the dishwasher, and affect the user experience.

[0050] Through the breather 100 used in the dishwasher, water enters the second channel 2 through the first flow channel 1 via the anti-siphon structure 3, so that the water overflowing through the anti-siphon structure 3 is used for the brine chamber water intake, avoiding water waste and preventing unsoftened water from entering the washing chamber, which would cause scale buildup inside the washing chamber. After the brine chamber is full, the excess water will flow into the washing chamber from the drain outlet 24, improving the dishwasher's working capacity.

[0051] Example 2

[0052] like Figures 1 to 4 As shown, this embodiment is a further limitation of the first embodiment described above. The second branch 23 includes a bent flow channel section 231, a protruding flow channel section 232, and a rotating flow channel section 233. The upper end of the bent flow channel section 231 is connected to the outlet of the first branch 22, and the lower end of the bent flow channel section 231 is connected to the upper end of the protruding flow channel section 232. The protruding flow channel section 232 protrudes axially from the first flow channel 1. An overflow outlet 25 connected to the upper end of the rotating flow channel section 233 is provided on the side wall of the protruding flow channel section 232 away from the outer periphery of the connecting port 6. The lower end of the rotating flow channel section 233 is provided with an outlet connected to the brine chamber.

[0053] In the above scheme, water flows through the outlet of the first branch 22 into the bent flow channel section 231, then through the bent flow channel section 231 into the protruding flow channel section 232, and finally through the protruding flow channel section 232 into the rotating flow channel section 233 and into the salt chamber. This allows the water overflowing from the anti-siphon structure 3 to be used for the salt chamber water intake, reducing water waste and improving the working capacity of the dishwasher.

[0054] like Figure 3 and Figure 4 As shown, in this example, an inner wall 221 is provided between the first branch 22 and the first flow channel 1. The inner wall 221 is provided with an anti-siphon structure 3 for the first flow channel 1 to enter the first branch 22. The lower end of the inner wall 221 is connected to the upper end of the side wall of the bent flow channel section 231 away from the outer periphery of the connecting port 6.

[0055] like Figure 3 and Figure 4 As shown, in this example, the bent flow channel section 231 includes a first arc-shaped wall 2311 near the outer periphery of the connecting port 6 and a second arc-shaped wall 2312 away from the outer periphery of the connecting port 6. The first arc-shaped wall 2311 and the second arc-shaped wall 2312 are adapted to the outer periphery of the connecting port 6. The upper end of the second arc-shaped wall 2312 is connected to the lower end of the inner wall 221, and the lower ends of the first arc-shaped wall 2311 and the second arc-shaped wall 2312 are connected to the protruding flow channel section 232.

[0056] In the above scheme, the first arc-shaped wall 2311 and the second arc-shaped wall 2312 are adapted to the outer periphery of the connecting port 6, which not only ensures that the water in the first branch 22 flows smoothly into the second branch 23 on the outer periphery of the connecting port 6, but also adjusts the water flow speed and direction in the second branch 23 to avoid excessive water flow speed during the downward flow of water.

[0057] like Figure 3 and Figure 4 As shown, in this example, the first branch 22 includes an inner wall 221 and an outer wall 222 on the opposite side. The lower end of the outer wall 222 is connected to the outer peripheral wall of the connecting port 6. The upper end of the first arc-shaped wall 2311 extends along the outer peripheral side of the connecting port 6 to the outer wall 222. There is a gap between the extended end of the first arc-shaped wall 2311 and the outer wall 222, which defines the vent for connecting the washing chamber.

[0058] In the above scheme, the extension end of the first arc-shaped wall 2311 and the outer wall 222 define a vent that connects to the washing chamber, so as to alleviate the safety accident caused by excessive pressure in the washing chamber.

[0059] like Figure 3 and Figure 4 As shown, in this example, the extended end of the first arc-shaped wall 2311 protrudes from the upper end of the second arc-shaped wall 2312. The inner wall 221 includes at least a first outwardly protruding section 2211 and an inwardly concave section 2212 connected sequentially from top to bottom. The anti-siphon structure 3 is disposed on the first outwardly protruding section 2211. The radius of curvature of the first outwardly protruding section 2211 gradually increases from top to bottom, while the radius of curvature of the inwardly concave section 2212 gradually decreases from bottom to top. The maximum radius of curvature of the inwardly concave section 2212 is smaller than the minimum radius of curvature of the first outwardly protruding section 2211. The lower end of the inwardly concave section 2212 is connected to the upper end of the second arc-shaped wall 2312. The outer wall 222 includes at least a second outwardly protruding section 2221 whose radius of curvature gradually decreases from top to bottom. The minimum radius of curvature of the second outwardly protruding section 2221 is larger than the maximum radius of curvature of the inwardly concave section 2212. The lower end of the second outwardly protruding section 2221 is connected to the outer peripheral wall of the connecting port 6.

[0060] In the above scheme, the maximum radius of curvature of the concave section 2212 is smaller than the minimum radius of curvature of the first convex section 2211, and the minimum radius of curvature of the second convex section 2221 is larger than the maximum radius of curvature of the concave section 2212, so as to ensure that the water of the first branch 22 flows into the second branch 23, and avoids the water from flowing into the washing chamber through the air vent of the washing chamber, so that the unsoftened water causes scale to form in the washing chamber.

[0061] like Figure 3 and Figure 4As shown, in this example, the protruding flow channel section 232 includes a first sidewall 2321 near the outer periphery of the connecting port 6 and a second sidewall 2322 away from the outer periphery of the connecting port 6. The first sidewall 2321 is provided with a diversion guide rib 26 extending to the second sidewall 2322. There is a gap between the extended end of the diversion guide rib 26 and the second sidewall 2322 for water to flow through. The second sidewall 2322 is provided with an overflow port 25 communicating with the rotary flow channel section 233, and the first sidewall 2321 is provided with a drain port 24 communicating with the washing chamber. The overflow port 25 and the drain port 24 are respectively located below the diversion guide rib 26.

[0062] In the above scheme, water is introduced into the brine chamber through the second flow channel 2. When the brine chamber is full, the excess water overflows from the overflow port 25 into the protruding flow channel section 232, and flows into the washing chamber through the drain port 24, thereby preventing the water overflowing from the brine chamber from leaking out through the air flow channel 4, causing water waste and affecting the user experience.

[0063] like Figure 1 and Figure 2 As shown, in this example, the respirator 100 also includes an air channel 4 that connects to the saline chamber. The rotary channel section 233 and the air channel 4 are arranged side by side. A partition rib 27 is provided between the rotary channel section 233 and the air channel 4. The air outlet 41 of the air channel 4 is higher than the drain outlet 24.

[0064] In the above scheme, in order to reduce the interface structure between the respirator 100 and the softener, the water channel and the air channel 4 are formed into a cylindrical structure at the connection part. The air channel 4 and the water channel are distributed on both sides of the cylindrical structure by the partition rib 27. This not only reduces the installation difficulty of the respirator 100 and the softener, but also prevents water leakage. In particular, the air outlet 41 of the air channel 4 is higher than the drain outlet 24. When the saline chamber is full, the excess water will flow from the overflow outlet 25 into the protruding channel section 232, and then enter the washing chamber through the drain outlet 24. It will not leak out from the air channel 4, thus avoiding waste of resources.

[0065] like Figure 3 and Figure 4 As shown, in this example, there is a gap between the bottom wall of the protruding flow channel section 232 and the bottom wall of the first flow channel 1 for water to flow through.

[0066] In the above scheme, the protruding flow channel section 232 is arranged in front of and behind the first flow channel 1, which not only makes the first flow channel 1 and the second flow channel 2 simpler and allows the water in the first flow channel 1 and the second flow channel 2 to flow smoothly downward, but also saves the internal space of the shell 101, making the internal structure of the respirator 100 more compact.

[0067] Specifically, water is supplied to the first flow channel 1 through the inlet 11. Part of the water in the first flow channel 1 flows into the second flow channel 2 through the anti-siphon structure 3, and the rest flows downward and into the resin chamber through the first outlet 12. The water overflowing from the anti-siphon structure 3 flows into the first branch 22 and then flows downward until it flows into the salt chamber through the second outlet 21. When the salt chamber is full, the excess water overflows from the overflow outlet 25 and flows into the protruding flow channel section 232 of the second branch 23, and then flows into the washing chamber from the drain outlet 24.

[0068] Through the breather 100 used in the dishwasher, water flows through the outlet of the first branch 22 into the bent flow channel section 231, then through the bent flow channel section 231 into the protruding flow channel section 232, and finally through the protruding flow channel section 232 into the rotating flow channel section 233 and into the salt chamber. This allows the water overflowing from the anti-siphon structure 3 to be used for the salt chamber water intake, reducing water waste and improving the dishwasher's working capacity.

[0069] Example 3

[0070] like Figure 1 and Figure 3 As shown, this embodiment is a further limitation of the first embodiment above. The housing 101 also has a drainage channel 5. The drainage channel 5 is provided with a sewage inlet 51, a sewage outlet 52 and a drainage vent 53. The sewage inlet 51 is connected to the washing chamber, the sewage outlet 52 is adapted to be connected to the sewer, and the drainage vent 53 is connected to the atmosphere.

[0071] Specifically, the wastewater generated in the washing chamber enters the drain channel 5 through the wastewater inlet 51, and then is discharged into the sewer through the wastewater outlet 52, thus realizing the dishwasher's drainage process. When the drainage process stops, a negative pressure will be formed in the upstream section of the drain channel 5, causing the water stagnant in the downstream section of the drain channel 5, which is connected to the sewer, to tend to flow back due to siphon. Since the drain vent 53 is connected to the atmosphere, air from the atmosphere can enter the drain channel 5 through the drain vent 53 to balance the pressure difference in the drain channel 5 and prevent siphoning from occurring in the drain channel 5.

[0072] The breather 100 used in the dishwasher can prevent water in the drain channel 5 from flowing back into the washing chamber of the dishwasher after drainage, ensuring that the water retained in the drain channel 5 is discharged smoothly.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
