[0002] Dishwasher breathers typically integrate a water inlet and drain chamber, partially consolidating the dishwasher's water flow, facilitating overall structural design and subsequent assembly. Currently, dishwasher water inlets typically utilize a single water channel, requiring only a single water source, typically tap water, to ensure proper water flow. Current dishwasher breathers are inadequate when two water sources are required—for example, one tap and the other a water tank.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] This embodiment discloses a respirator with dual water inlet, referring to Figure 1-Figure 5 As shown, the dishwasher comprises a housing 10 , in which a water inlet chamber 20 and a drainage chamber 30 are provided. The water inlet chamber 20 is used for fresh water intake of the dishwasher, and the drainage chamber 30 is used for sewage drainage.

[0028] The housing 10 is provided with a water inlet joint 1 21, a water inlet joint 2 22, a water drain joint 1 31, and a water drain joint 2 32. Water in the water inlet chamber 20 enters through the water inlet joint 1 21, flows through the water inlet channel within the water inlet chamber 20, and exits through the water inlet joint 2 22. Water in the water drain chamber 30 enters through the water drain joint 1 31, flows through the water drain channel within the water drain chamber 30, and exits through the water drain joint 2 32.

[0029] In this embodiment, the water inlet chamber connector 1 21 has a three-way structure, one of which connects to the water inlet chamber 20, and the other two connects to form two water inlets 211. A three-way chamber 210 is provided within the water inlet chamber connector 1 21, and a limiting fluid 213 is provided within the three-way chamber 210. The limiting fluid 213 is capable of moving between the two water inlets 211. When water is flowing into the water inlet chamber 20, it can switch between the two water inlets 211, allowing simultaneous connection to two water sources, allowing the user to select either water source during use. When water flows into one water inlet 211, the limiting fluid 213 is affected by the water pressure and moves toward the other water inlet 211, where it can be blocked at the other water inlet 211.

[0030] The flow-limiting body 213 can not only select the water inlet 211 to be used, but also block the water inlet 211 that is not receiving water under the action of the incoming water pressure, thereby avoiding water leakage.

[0031] Reference Figure 4 、 Figure 5 As shown, two water inlets 211 are located at either end of the three-way cavity 210, forming a passage from one water inlet 211 to the other. The limiting body 213 is generally spherical in shape, and the inner diameter of the three-way cavity 210 is slightly larger than the outer diameter of the limiting body 213, allowing the limiting body 213 to move smoothly within the three-way cavity 210. The point where the three-way cavity 210 connects to the water inlet cavity 20 is located between the two water inlets 211. The movement of the limiting body 213 selects the water inlet 211 that is connected to the water inlet cavity 20, achieving switching between the two water inlets 211.

[0032] An opening 212 is provided on the outside of the three-way cavity 210 , through which a limiting fluid 213 can be placed into the three-way cavity 210 , and a plug 214 is installed at the opening 212 to seal the opening 212 and confine the limiting fluid 213 inside.

[0033] Spherical portions 215 are formed at each end of the three-way cavity 210, with two water inlets 211 located in the respective spherical portions 215. The flow-restricting body 213 is adapted to fit within the spherical portions 215. When the flow-restricting body 213 is subjected to water pressure and moves to the spherical portions 215, it abuts against the surface of the spherical portions 215, forming a spherical sealing structure that seals the corresponding water inlets 211. The spherical portions 215 can also be tapered, forming a bell-shaped structure, to also form a pressure seal with the spherical flow-restricting body 213.

[0034] Generally, the two water inlets 211 of the water inlet joint 1 21 are arranged downward, and the position where the water inlet joint 1 21 connects to the water inlet chamber 20 is located on the upper side. The water inlet joint 1 21 is generally formed into an inverted U-shaped structure. At the same time, the three-way cavity 210 within the water inlet joint 1 21 is also generally formed into an inverted U-shaped structure.

[0035] Reference Figure 2 、 Figure 3 As shown, in this embodiment, the housing 10 is further provided with a detection chamber 40, and a flow meter module 50 is installed in the detection chamber 40. The flow meter module 50 can detect the water flow in the water inlet chamber 20 and the total amount of water inlet into the dishwasher.

[0036] Reference Figure 5 As shown, the detection chamber 40 is located between the water inlet chamber 20 and the water inlet chamber connector 1 21. The water inlet chamber connector 1 21 is connected to the water inlet chamber 20 through the detection chamber 40. Clean water input from the water inlet chamber connector 1 21 first flows through the detection chamber 40 and then enters the detection chamber 40, enabling the input flow rate to be detected.

[0037] Specifically, a through hole 1 41 and a through hole 2 42 are formed in the sidewall of the detection chamber 40. The detection chamber 40 is connected to the input end of the water inlet chamber 20 through the through hole 1 41. The detection chamber 40 is connected to the water inlet chamber 20 at the water inlet chamber connector 1 21 through the through hole 2 42. The connection position of the through hole 2 42 is located between the two water inlets 211 of the three-way chamber 210, that is, in the middle section of the three-way chamber 210.

[0038] Reference Figure 2 、 Figure 3 As shown, in this embodiment, the housing 10 includes a bottom shell 11 and a cover 12. The cover 12 is fixedly connected to the bottom shell 11 to cover the bottom shell 11. Generally, the bottom shell 11 and the cover 12 can be connected and fixed by heat welding.

[0039] The detection chamber 40 is formed in the bottom shell 11 and has an opening. The flowmeter module 50 includes a flowmeter body 51 and a rotating blade 52. The flowmeter body 51 is fixedly mounted at the opening of the detection chamber 40. The rotating blade 52 extends into the detection chamber 40 and can detect flow parameters within the detection chamber 40. The detection chamber 40 can be fixed by bolts, and the opening of the detection chamber 40 can be covered and sealed. The flowmeter module 5 can specifically adopt the distance of a Hall flowmeter, which will not be detailed here.

[0040] The cover 12 defines a clearance notch 121, which aligns with the opening of the flow detection chamber 111. When the cover 12 and the bottom shell 11 are closed, the clearance notch 121 aligns with the flow detection chamber 111, making it easy to install the flow meter module 50 through the clearance notch 121 after the two are closed and secured. At least a portion of the flow meter body 51 is exposed outside the housing 1 through the clearance notch 121, facilitating installation and subsequent maintenance of the flow meter module 50.

[0041] Further, refer to Figure 2 、 Figure 4 As shown, the water inlet chamber 20 forms a water inlet channel between the water inlet chamber joint 1 21 and the water inlet chamber joint 2 22. The water inlet channel first bends upward and then bends downward to connect the water inlet chamber joint 1 21 and the water inlet chamber joint 2 22. A throttling plate 70 is installed in the water inlet channel of the water inlet chamber 20.

[0042] Reference Figure 4 The drainage chamber 30 is shaped like an inverted U, with drainage chamber connector 1 31 and drainage chamber connector 2 located at the lower ends of the U-shaped structure. A connecting chamber 33 is defined within the housing 10. This connecting chamber 33 is located above the drainage chamber 4, and its lower side communicates with the outlet of the drainage chamber 4 via a connecting port 331.

[0043] A one-way valve is installed on the upper side of the connecting chamber 33, which enables one-way communication with the external environment. External air can enter the connecting chamber 33 through the one-way valve, thereby one-way communication with the external environment, the connecting chamber 33 and the drainage chamber 30.

[0044] When the dishwasher finishes draining, the water in the drain chamber 30 is at a high level. Due to gravity, the water moves downward, sucking air into the drain chamber 30, which in turn causes the pressure in the connecting chamber 33 to drop. At this point, the one-way valve, pressed downward by external pressure, opens in one direction, allowing the outside environment, the connecting chamber 33, and the drain chamber 30 to flow. This allows air to enter the drain chamber 30, allowing the water in the drain chamber 30 to drain smoothly. Air can enter the drain chamber 30 through the connecting chamber 33 and the connecting port 331, disrupting the siphon effect within the drain chamber 30 and preventing the water in the inner tank from being directly siphoned out.

[0045] This embodiment also discloses a dishwasher, including a breather as in the above embodiment, in which multiple flow paths of the dishwasher are integrated, and the breather can balance the pressure difference environment of each flow path and the inner tank of the dishwasher, balance the working pressure of the dishwasher, and maintain normal and stable operation of the dishwasher.

[0046] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
