[0002] The breather is an important component in the dish-washing machine, and has the function of balancing the pressure inside the dish-washing machine. The breather is provided with a water inlet channel and a water outlet channel. The water inlet channel has a water inlet and a water outlet. The water inlet is connected to an external water source, and the water outlet is connected to a water softener. Thus, the external water flow is input into the water softener. The water outlet channel has a sewage inlet and a sewage outlet. The sewage inlet is connected to the inner container of the dish-washing machine, and the sewage outlet is connected to an external drainage device. Thus, the sewage in the inner container is discharged. However, when the water inlet is closed, the water outlet will have a tendency of backflow due to siphonage. When the sewage inlet is closed, the water at the sewage outlet will have a tendency of backflow due to siphonage. Therefore, an anti-siphon channel is usually arranged in the breather and is connected to the water inlet channel and the water outlet channel. The anti-siphon channel is connected to the external atmosphere through a breathing port. Thus, the effect of preventing siphonage is achieved. However, during the long-term use of the breather, a slight water leakage phenomenon may occur. That is, part of the water flow in the water inlet channel or the water outlet channel directly flows into the anti-siphon channel and then flows out from the breathing port. Thus, the water flow may accumulate around the inner container of the dish-washing machine.

[0038] Reference Figures 1 to 6The utility model discloses an embodiment proposes a respirator, including casing 100, be provided with water inlet channel 200, drainage channel 300, air cavity 600, first antisiphon channel 400, second antisiphon channel 500 and flow guide channel 630 in casing 100. Water inlet channel 200 has water inlet 201 and water outlet 202, and drainage channel 300 has sewage inlet 301 and sewage outlet 302. The lateral wall of casing 100 is provided with the communication hole 610 being linked with air cavity 600 and first breathing mouth 620, the communication hole 610 is used to be linked with the inner container, and first breathing mouth 620 is used to be linked with the outside atmosphere, and the horizontal height of communication hole 610 is lower than the horizontal height of first breathing mouth 620. First antisiphon channel 400 one end is linked with water inlet channel 200, and the other end has first antisiphon hole 410 being linked with air cavity 600, and the horizontal height of first antisiphon hole 410 is located between the horizontal height of communication hole 610 and the horizontal height of first breathing mouth 620, and first antisiphon channel 400 is equipped with first sealing piece 420 for opening or closing first antisiphon hole 410. The lower end of second antisiphon channel 500 is linked with drainage channel 300, and the upper end has second antisiphon hole 510 being linked with air cavity 600, and the horizontal height of second antisiphon hole 510 is located between the horizontal height of communication hole 610 and the horizontal height of first breathing mouth 620, and second antisiphon channel 500 is equipped with second sealing piece 520 for opening or closing second antisiphon hole 510. Flow guide channel 630, be located in casing 100 and be located in air cavity 600, and flow guide channel 630 is linked with first antisiphon hole 410, second antisiphon hole 510, and the upper end of flow guide channel 630 has the air hole 640 being linked with first breathing mouth 620, and the lower end of flow guide channel 630 extends to be linked with communication hole 610.

[0039] By adopting the breather of the embodiment of the utility model, the communication hole 610 can be communicated with the inner container of the dishwasher, and thus the air pressure inside and outside the inner container can be balanced through the air cavity 600 and the first breathing port 620. The water inlet 201 is communicated with the external water source, and the water outlet 202 is communicated with the water inlet pipe of the water softener, and thus the external water can be transported into the water softener to be softened, and the softened water can be discharged from the water softener to the inner container of the dishwasher to clean the tableware. During the water inlet process, when the water inlet 201 is closed to cause the negative pressure of the water inlet channel 200, the water at the water outlet 202 will have the tendency of backflow due to siphon, at this time, the first sealing piece 420 is controlled to open the first anti-siphon hole 410, and the external air can enter the air cavity 600 through the first breathing port 620 and then pass through the communication hole 610, the first anti-siphon hole 410 and the first anti-siphon channel 400, and thus the air pressure inside and outside the water inlet channel 200 can be balanced, the effect of preventing siphon can be achieved, if the water inlet channel 200 has slight water leakage during long-term use, that is, the water flow enters the first anti-siphon channel 400 from the water inlet channel 200 and seeps into the air cavity 600 from the first anti-siphon hole 410, at this time, the flow channel 630 is arranged, the horizontal height of the communication hole 610 is lower than the horizontal height of the first breathing port 620, and the horizontal height of the first anti-siphon hole 410 is between the horizontal height of the communication hole 610 and the horizontal height of the first breathing port 620, and thus the water flowing out of the first anti-siphon hole 410 is not easy to flow upwards to the first breathing port 620, but directly flows into the flow channel 630 and flows downwards along the flow channel 630 to the communication hole 610, and thus can flow back to the inner container of the dishwasher for tableware cleaning, and thus the water seeping out of the first anti-siphon hole 410 can be prevented from flowing out of the first breathing port 620 to the outer periphery of the inner container, and thus the reliability of the breather can be improved, and the use experience of the user can be improved.

[0040] In addition, the sewage inlet 301 is connected with the drain pipe of the dishwasher, and the sewage outlet 302 is connected with the external drainage device, so that the sewage in the inner container can be discharged to the outside. During the drainage process, when the sewage inlet 301 is closed to cause negative pressure in the water inlet channel 200, the water at the sewage outlet 302 has a tendency to backflow due to siphon. At this time, the second sealing member 520 is controlled to open the second anti-siphon hole 510, and the external air can enter the air cavity 600 through the first breathing port 620, and then pass through the vent hole 640, the second anti-siphon hole 510 and the second anti-siphon channel 500, so as to balance the air pressure inside and outside the drainage channel 300, and achieve the effect of anti-siphon. If the drainage channel 300 has a slight leakage during long-term use, that is, there is a phenomenon that the water flow enters the second anti-siphon channel 500 from the drainage channel 300 and seeps into the air cavity 600 from the second anti-siphon hole 510. At this time, by arranging the flow guide channel 630, and setting the horizontal height of the communication hole 610 to be lower than the horizontal height of the first breathing port 620, and the horizontal height of the second anti-siphon hole 510 is between the horizontal height of the communication hole 610 and the horizontal height of the first breathing port 620, the water flowing out of the second anti-siphon hole 510 will directly flow into the flow guide channel 630 and flow downward along the flow guide channel 630 to the communication hole 610, so as to flow back to the dishwasher inner container. Therefore, it can prevent the sewage from seeping out of the second anti-siphon hole 510 and flowing out of the first breathing port 620 to the outer periphery of the inner container, thereby causing pollution to the outer periphery of the inner container, and further improving the reliability of the breather and the user's use experience.

[0041] With reference to Figures 1 to 6 In some embodiments, the first anti-siphon channel 400 and the second anti-siphon channel 500 both extend to the right side of the flow guide channel 630, the first anti-siphon hole 410 and the second anti-siphon hole 510 are both arranged on the right side wall of the flow guide channel 630, and the first anti-siphon hole 410 and the second anti-siphon hole 510 are both arranged inclined to the left from top to bottom. The right side wall of the flow guide channel 630 is further provided with a flow guide surface 631 located between the first anti-siphon hole 410 and the second anti-siphon hole 510, and the flow guide surface 631 is connected to the lower edge of the first anti-siphon hole 410 and arranged inclined to the left from top to bottom.

[0042] By adopting the above structure, by arranging the first anti-siphon hole 410 to be inclined from top to bottom to the left, external air can flow from top to bottom to the right through the first anti-siphon hole 410 into the first anti-siphon channel 400, and the difficulty of water in the first anti-siphon channel 400 flowing out to the flow guide channel 630 through the first anti-siphon hole 410 can be increased, thereby not only better improving the anti-siphon effect, but also further preventing water in the water inlet channel 200 from leaking out of the first anti-siphon hole 410, which is beneficial to improve the reliability of the respirator. By arranging the flow guide surface 631 connected to the lower edge of the first anti-siphon hole 410 and inclined from top to bottom to the left, when water in the water inlet channel 200 seeps out of the first anti-siphon hole 410, it can guide the water to flow downward into the flow guide channel 630, and then flow downward along the flow guide channel 630 to the communication hole 610, thereby further preventing the first breathing port 620 of the respirator from leaking, which is beneficial to improve the reliability of the respirator. Similarly, by arranging the second anti-siphon hole 510 to be inclined from top to bottom to the left, external air can flow from top to bottom to the right through the second anti-siphon hole 510 into the second anti-siphon channel 500, and the difficulty of water in the second anti-siphon channel 500 flowing out to the flow guide channel 630 through the second anti-siphon hole 510 can be increased, thereby not only better improving the anti-siphon effect, but also further preventing water in the water outlet channel 300 from leaking out of the second anti-siphon hole 510, which is beneficial to improve the reliability of the respirator

[0043] With reference to Figures 1 to 6 In some embodiments, the first anti-siphon channel 400 is provided with a first plug-in portion 430 located on one side of the first anti-siphon hole 410, and one end of the first sealing member 420 is plugged into the first plug-in portion 430, and the other end is fitted with the periphery of the first anti-siphon hole 410. The first sealing member 420 can be deformed and open the first anti-siphon hole 410 under the action of external force.

[0044] By adopting the above structure, not only the structure of the first sealing member 420 is simpler and easier to install, but also the sealing performance of the first sealing member 420 is improved while the anti-siphon effect is ensured. Specifically, in the normal water inlet process, the first sealing member 420 can be attached to the periphery of the first anti-siphon hole 410 to close the first anti-siphon hole 410. When the siphon phenomenon occurs in the water inlet channel 200, the external air pressure is greater than the air pressure in the water inlet channel 200, the external air flows into the breathing cavity through the first breathing hole, and then pushes the first sealing member 420 outward from the second anti-siphon hole 510 to open the second anti-siphon hole 510. Thus, the external air can enter the second anti-siphon channel 500 through the second anti-siphon hole 510 to balance the air pressure in the water inlet channel 200. When the water in the water inlet channel 200 enters the anti-siphon channel and tends to flow outward, the water flow directly presses the first sealing member 420 to make the first sealing member 420 more attached to the periphery of the first anti-siphon hole 410. Thus, the sealing performance of the first sealing member 420 is improved, the water in the water inlet channel 200 is better prevented from leaking from the first anti-siphon hole 410, and the reliability of the breather is improved.

[0045] With reference to Figures 1 to 6 In some embodiments, the second anti-siphon channel 500 is provided with a second insertion part 530 located on one side of the second anti-siphon hole 510, and one end of the second sealing member 520 is inserted into the second insertion part 530 and the other end is attached to the periphery of the second anti-siphon hole 510. The second sealing member 520 can be deformed under external force to open the second anti-siphon hole 510.

[0046] By adopting the above structure, not only the structure of the second sealing member 520 is simpler and easier to install, but also the sealing performance of the second sealing member 520 is improved while the anti-siphon effect is ensured. Specifically, in the normal water inlet process, the second sealing member 520 can be attached to the periphery of the second anti-siphon hole 510 to close the second anti-siphon hole 510. When the siphon phenomenon occurs in the water inlet channel 200, the external air pressure is greater than the air pressure in the water inlet channel 200, the external air flows into the breathing cavity through the first breathing hole, and then pushes the first sealing member 420 outward from the second anti-siphon hole 510 to open the second anti-siphon hole 510. Thus, the external air can enter the second anti-siphon channel 500 through the second anti-siphon hole 510 to balance the air pressure in the water inlet channel 200. When the water in the water inlet channel 200 enters the anti-siphon channel and tends to flow outward, the water flow directly presses the first sealing member 420 to make the first sealing member 420 more attached to the periphery of the first anti-siphon hole 410. Thus, the sealing performance of the first sealing member 420 is improved, the water in the water inlet channel 200 is better prevented from leaking from the first anti-siphon hole 410, and the reliability of the breather is improved.

[0047] It can be understood that the first seal 420 and the second seal 520 can adopt flexible sealing structures such as rubber or silica gel, and the utility model does not make specific limitation.

[0048] It can be understood that in addition to the above structure, the first seal 420 and the second seal 520 can also directly adopt valve structures such as stop valves and control valves, and the utility model does not make specific limitation.

[0049] Referring to Figures 1 to 6 In some embodiments, the shell 100 includes a first shell 110 and a second shell 120, and the water inlet channel 200, the water outlet channel 300, the air cavity 600, the first anti-siphon channel 400 and the second anti-siphon channel 500 are all defined by the first shell 110 and the second shell 120. The first insertion part 430 and the second insertion part 530 are both arranged in the first shell 110, the first insertion part 430 is provided with a first insertion opening for inserting the first seal 420, the second insertion part 530 is provided with a second insertion opening for inserting the second seal 520, and the second shell 120 is provided with a first pressing part 440 and a second pressing part 540 corresponding to the first insertion part 430 and the second insertion part 530. When the first shell 110 and the second shell 120 are buckled to each other, the first pressing part 440 presses the first insertion opening and limits the first seal 420 in the first insertion part 430, and the second pressing part 540 presses the second insertion opening and limits the second seal 520 in the second insertion part 530.

[0050] In the above structure, by arranging the first pressing part 440 and the second pressing part 540, when installing, the first seal 420 is inserted into the first insertion part 430 through the first insertion opening, and the second seal 520 is inserted into the second insertion part 530 through the second insertion opening. When the first shell 110 and the second shell 120 are buckled to each other, the first pressing part 440 presses the first insertion opening and limits the first seal 420 in the first insertion part 430, and the second pressing part 540 presses the second insertion opening and limits the second seal 520 in the second insertion part 530. Therefore, the installation of the first seal 420 and the second seal 520 is more convenient and stable.

[0051] It can be understood that in order to further improve the installation stability of the first seal 420 and the second seal 520, in some embodiments, the first seal 420 can be interference-fitted with the first insertion part 430, and the second seal 520 can be interference-fitted with the second insertion part 530.

[0052] It can be understood that the first shell 110 and the second shell 120 can be connected by welding, so that the sealing performance of the respirator shell 100 can be improved. Of course, in addition, the first shell 110 and the second shell 120 can also be connected by clamping or fastening screws, and the like, which are not limited in the present application.

[0053] With reference to Figures 1 to 6 In some embodiments, the water inlet channel 200 comprises a first water inlet section 210, a first communication section 220 and a first water outlet section 230, the upper end of the first water inlet section 210 is connected to the upper end of the first water outlet section 230 through the first communication section 220, the water inlet 201 is located at the lower end of the first water inlet section 210, and the water outlet 202 is located at the lower end of the first water outlet section 230; the first anti-siphon channel 400 is located on the left side of the first communication section 220 and is connected to the first communication section 220.

[0054] By adopting the above structure, the structure of the water inlet channel 200 can be simplified, and by arranging the first anti-siphon channel 400 on one side of the first communication section 220, the air pressure inside and outside the water inlet channel 200 can be balanced in time when the siphon phenomenon occurs in the water inlet channel 200, and the risk of water backflow at the water outlet 202 can be reduced.

[0055] With reference to Figures 1 to 6 In some embodiments, the water outlet channel 300 comprises a second water inlet section 310, a second communication section 320 and a second water outlet section 330, the upper end of the second water inlet section 310 is connected to the upper end of the second water outlet section 330 through the second communication section 320, the sewage inlet 301 is located at the lower end of the second water inlet section 310, and the sewage outlet 302 is located at the lower end of the second water outlet section 330.

[0056] By adopting the above structure, the structure of the water outlet channel 300 can be simplified. By arranging the second anti-siphon channel 500 above the second water outlet section 330 and connecting it to the second water outlet section 330, the sewage flowing from the sewage inlet 301 into the first water inlet section 210 can be prevented from directly flowing into the second anti-siphon channel.

[0057] With reference to Figures 1 to 6In some embodiments, the housing 100 has a condensation channel 700 located on the left side of the air cavity 600. A return water hole 710 communicating with a connecting hole 610 is provided on the right side wall of the condensation channel 700. The return water hole 710 is located at the lower end of the condensation channel 700. A turbulence-inducing component and a first guide plate 720 are provided within the condensation channel 700. The first guide plate 720 is located at the lower end of the turbulence-inducing component and extends from top to bottom and to the right to connect with the lower edge of the return water hole 710. A gap exists between the left end of the first guide plate 720 and the left side wall of the condensation channel 700. A second vent 740 located below the condensation channel 700 is provided on the side wall of the housing 100. The horizontal height of the second vent 740 is lower than the horizontal height of the connecting hole 610.

[0058] By adopting the above structure, the humid hot water vapor in the inner liner can flow into the air cavity 600 through the connecting hole 610, and then be condensed by the turbulence component of the condensation channel 700. The condensed low-temperature air can flow downward to the second vent 740 and be discharged from the second vent 740. The condensed water can flow from top to bottom to the first guide plate 720 and flow downward along the first guide plate 720 to the return water hole 710, and then flow back into the inner liner through the connecting hole. It can be seen that this structure can also achieve the effect of venting the inner liner, avoiding high pressure in the inner liner, and also preventing humid hot air from being directly discharged and scalding the user.

[0059] Reference Figures 1 to 6 In some embodiments, the spoiler assembly includes at least two spoilers 730, all of which are staggered in the vertical direction.

[0060] In two adjacent spoilers 730, one spoiler 730 is tilted to the left from top to bottom and is arranged at a distance from the left side wall of the condensation channel 700, and the other spoiler 730 is tilted to the right from top to bottom and is arranged at a distance from the right side wall of the condensation channel 700. The projection of the lower end of the upper spoiler 730 in the vertical direction falls on the lower spoiler 730.

[0061] By adopting the above structure, the spoiler 730 can block the flow of hot and humid air. The hot and humid air can flow down along the spoiler 730 and then fall onto the next spoiler 730. This allows the hot and humid air to pass through all the spoilers 730 as much as possible, which is beneficial to greatly improve the condensation effect of the hot and humid air.

[0062] Reference Figures 1 to 6In some embodiments, the first breathing port 620 is located above the condensation channel 700, the housing 100 is provided with a blocking portion 750 located on the left side and the upper side of the first breathing port 620, the upper end of the right side wall of the condensation channel 700 is provided with a second flow guide plate 760 extending to the left and facing the first breathing port 620, the upper end of the left side wall of the condensation channel 700 is provided with a third flow guide plate 770 inclined to the right from top to bottom, the third flow guide plate 770 is connected with the blocking portion 750 and located below the first breathing port 620, the second flow guide plate 760 and the third flow guide plate 770 are arranged in a spaced manner and form a condensation inlet 780 communicating the condensation channel 700 and the air cavity 600.

[0063] By adopting the above structure, when the humid hot air flows into the air cavity 600 from the communication port, the humid hot air can flow along the air cavity 600 towards the first breathing port 620, the second flow guide plate 760 can guide the humid hot air to flow towards the blocking portion 750 located on the left side and the upper side of the first breathing port 620, the blocking portion 750 can block the flow of the humid hot air, the humid hot air changes the flow direction after being hindered by the blocking portion 750, and then flows downwards along the third flow guide plate 770 to the condensation inlet 780, and then flows downwards along the condensation channel 700. The structure can hinder the humid hot air from being directly discharged from the first breathing port 620, guide the humid hot air to flow downwards into the condensation channel 700, thereby avoiding the situation that the humid hot air is directly discharged from the first breathing port 620 to scald the user.

[0064] An embodiment of the utility model also provides a dish washing machine, the dish washing machine is provided with the breather of any one embodiment.

[0065] In the dishwasher of the embodiment of the utility model, through adopting the breather of any one of the above embodiments, when in use, the communication hole 610 is communicated with the inner container of the dishwasher, so that the air pressure inside and outside the inner container can be balanced through the air cavity 600 and the first breathing port 620. The water inlet 201 is communicated with the external water source, and the water outlet 202 is communicated with the water inlet pipe of the water softener, so that the external water can be transported into the water softener for softening, and the softened water can be discharged from the water softener to the inner container of the dishwasher for cleaning tableware. The sewage inlet 301 is communicated with the drain pipe of the dishwasher, and the sewage outlet 302 is communicated with the external drainage device, so that the sewage in the inner container can be discharged to the outside. The first anti-siphon channel 400 and the second anti-siphon channel 500 can conveniently balance the air pressure inside and outside the water inlet channel 200 and the drainage channel 300. In addition, since the flow guide channel 630 is arranged in the shell 100, the horizontal height of the communication hole 610 is lower than that of the first breathing port 620, and the horizontal height of the first anti-siphon hole 410 and the second anti-siphon hole 510 is between the horizontal height of the communication hole 610 and the horizontal height of the first breathing port 620, so that when water seeps from the first anti-siphon hole 410 and the second anti-siphon hole 510, the water can be guided to flow back to the inner container, avoiding the water from flowing into the first breathing port 620 after seeping from the first anti-siphon hole 410 and the second anti-siphon hole 510, so that the water can be prevented from flowing out of the first breathing port 620 to the outer periphery of the inner container, thus conveniently cleaning the dishwasher, improving the reliability of the dishwasher, and improving the user's use experience.
