DETAILED DESCRIPTION

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0019] As Figure 1The water inlet device 10 of the washing equipment according to the embodiment of the utility model, the washing equipment can be dish washer or washing machine etc., the water inlet device 10 is used for washing equipment water inlet. Wherein water inlet device 10 can include main part 11 and air inlet control unit 12, main part 11 has air inlet 1011, liquid inlet 1012, liquid outlet 1013, dissolved gas cavity 102, first flow channel 103 and second flow channel 104, air inlet 1011 is communicated with outside, that is to say, air inlet 1011 is communicated with the external space of washing equipment, so as to utilize the air inlet 1011 to pass in air, to balance the internal and external air pressure, realize water inlet anti-siphon. Liquid inlet 1012 is used to pass in liquid to dissolved gas cavity 102, can pass in water, liquid with detergent etc. to dissolved gas cavity 102 according to need utilizing liquid inlet 1012, wherein liquid inlet 1012 is preferably used to pass in liquid with certain pressure, so as to gas-liquid mixing in dissolved gas cavity 102. Liquid outlet 1013 is used to discharge the mixed gas-liquid mixed fluid.

[0020] Wherein, dissolved gas cavity 102 is communicated with liquid outlet 1013, and dissolved gas cavity 102 is used for gas and liquid to mix fully, and liquid outlet 1013 is used to discharge the liquid containing gas from dissolved gas cavity 102. Second flow channel 104 is communicated with liquid inlet 1012 and dissolved gas cavity 102, and the liquid entering liquid inlet 1012 can pass into dissolved gas cavity 102 along second flow channel 104. First flow channel 103 is communicated with dissolved gas cavity 102 and second flow channel 104, wherein the gas entering air inlet 1011 can pass into dissolved gas cavity 102, and the gas not dissolved into liquid in dissolved gas cavity 102 can flow into second flow channel 104 along first flow channel 103. Air inlet control unit 12 is configured to one-way air inlet from air inlet 1011 to dissolved gas cavity 102, that is to say, when negative pressure is generated in dissolved gas cavity 102, the gas can be sent into dissolved gas cavity 102 from air inlet 1011, and when positive pressure or normal pressure (greater than or equal to the air supply pressure of air inlet 1011) is generated in dissolved gas cavity 102, the fluid in dissolved gas cavity 102 cannot be discharged from air inlet 1011.

[0021] Optionally, during the water inlet process, the liquid can pass into second flow channel 104 through liquid inlet 1012 and enter dissolved gas cavity 102 through second flow channel 104, and in the process of the liquid entering dissolved gas cavity 102 through second flow channel 104, the gas can pass into second flow channel 104 through first flow channel 103, to realize gas-liquid mixing. Specifically, when negative pressure is formed in second flow channel 104, the gas not dissolved into liquid in dissolved gas cavity 102 can enter first flow channel 103 and pass into second flow channel 104 along first flow channel 103, to realize gas-liquid mixing, and when negative pressure is generated in dissolved gas cavity 102, the external gas can pass into the air inlet channel through air inlet 1011 and enter dissolved gas cavity 102 through the air inlet channel.

[0022] The water inlet device 10 of the washing equipment according to the embodiment of the utility model, bubble generating device is integrated to water inlet device 10, and the water inlet of bubble generating device 1011 can be used to realize the water inlet anti-siphon of water inlet device 10, the structure of water inlet device 10 can be simplified, and the integration of the dishwasher is improved.

[0023] As Figure 1 In some embodiments, the air inlet control unit 12 is arranged at the air inlet 1011 and is configured to open the air inlet 1011 when a negative pressure is generated in the dissolved air cavity 102, for introducing gas into the second flow channel 104. The air inlet control unit 12 can be used to integrate the air inlet module and the water inlet anti-siphon module. The air inlet control unit 12 is used to introduce gas into the dissolved air cavity 102, and at the same time, has the effect of water inlet anti-siphon.

[0024] Specifically, by arranging the air inlet control unit 12, a closed chamber can be formed in the dissolved air cavity 102, so as to facilitate the mixing of gas and liquid with a certain pressure in the dissolved air cavity 102, and improve the gas-liquid mixing effect. In addition, when a negative pressure exists in the dissolved air cavity 102, the air inlet control unit 12 can be opened to supplement air into the dissolved air cavity 102, so as to realize air inlet anti-siphon.

[0025] Optionally, the air inlet control unit 12 is a first one-way valve, wherein the first one-way valve is arranged to be one-way conducted in the air inlet direction. That is, the gas outside the air inlet 1011 can enter the first flow channel 103 through the first one-way valve; and when the dissolved air cavity 102 is under positive pressure or normal pressure, the first one-way valve is not opened, so as to maintain a high dissolved air rate in the dissolved air cavity 102.

[0026] In addition, the air inlet control unit 12 can also be an electrically controlled valve. The electrically controlled valve can be opened and closed according to the air pressure of the dissolved air cavity 102. Specifically, the electrically controlled valve is opened when a negative pressure is generated in the dissolved air cavity 102; and the electrically controlled valve is closed when the dissolved air cavity 102 is under positive pressure or normal pressure. For example, when the dissolved air cavity 102 is under negative pressure, at this time, the gas can enter the dissolved air cavity 102 through the electrically controlled valve to realize water inlet anti-siphon. In addition, when the air pressure of the dissolved air cavity 102 is the same as the air inlet pressure (i.e. atmospheric pressure) of the air inlet 1011, the air pressure in the dissolved air cavity 102 is normal pressure; and when the air pressure in the dissolved air cavity 102 is greater than the air inlet pressure of the air inlet 1011, the air pressure in the dissolved air cavity 102 is positive pressure.

[0027] As Figure 1 In some embodiments, the first flow channel 103 extends in the up-down direction, the upper end of the first flow channel 103 communicates with the upper part of the dissolved air cavity 102, and the lower end communicates with the second flow channel 104. The first flow channel 103 can be used to introduce gas into the second flow channel 104 to realize water-gas mixing, which can reduce the outlet height of the second flow channel 104, so as to facilitate water inlet in the dissolved air cavity 102 and reduce the problem of overflow caused by high water level in the dissolved air cavity 102.

[0028] Optionally, the air inlet 1011 and the first flow channel 103 are arranged on both sides of the air dissolving cavity 102 along the left-right direction, which can realize uniform arrangement of the air inlet 1011, the air dissolving cavity 102, the second flow channel 104, the first flow channel 103, etc., facilitate the air to be introduced into the water inlet device 10, and improve the air dissolving rate.

[0029] In some embodiments, the second flow channel 104 includes a Venturi pipe 1041, and the first flow channel 103 is communicated with the Venturi pipe 1041. The Venturi pipe 1041 can have a Venturi structure for simultaneously bringing the gas and the liquid into the air dissolving cavity 102. The Venturi pipe 1041 is provided with an air inlet hole, a liquid inlet hole and a mixed outlet hole, the air inlet hole is communicated with the air inlet 1011, the liquid inlet hole is communicated with the liquid inlet 1012, and the mixed outlet hole is communicated with the air dissolving cavity 102.

[0030] It should be noted that the Venturi pipe 1041 is internally provided with a Venturi structure, and from the inlet to the outlet of the Venturi pipe 1041, the Venturi structure can be set to gradually decrease in cross section and then gradually increase, so that when the liquid passes through the narrow channel, a negative pressure area can be formed in the Venturi pipe 1041, the gas in the first flow channel 103 is sucked in, the liquid and the gas are mixed for the first time, and the mixed gas and liquid enter the air dissolving cavity 102 to be mixed for the second time, thereby improving the mixing characteristics of the liquid and the gas.

[0031] The air dissolving cavity 102 is communicated with the upper end of the Venturi pipe 1041, such as Figure 1 The air dissolving cavity 102 is distributed along the up-down direction, and the upper region of the air dissolving cavity 102 is communicated with the upper end of the Venturi pipe 1041, so that the gas and liquid mixture in the Venturi pipe 1041 enters the upper region of the air dissolving cavity 102, the mixing of the gas and the liquid continues in the air dissolving cavity 102, and the gas and liquid mixture flows downward along the vertical direction, which can improve the flow rate of the gas and liquid mixture, thereby improving the speed of the liquid delivered to the washing space, and improving the cleaning efficiency and cleaning quality of the articles.

[0032] Optionally, the second flow channel 104 further includes a water inlet section 1042, the water inlet section 1042 extends along the up-down direction, the lower end of the water inlet section 1042 is communicated with the liquid inlet 1012, and the upper end is communicated with the Venturi pipe 1041. The liquid can be conveniently introduced into the second flow channel 104 through the liquid inlet 1012, and the water inlet section 1042 is used to guide the liquid to flow to the Venturi pipe 1041, thereby simplifying the liquid inlet structure.

[0033] Further, the Venturi tube 1041 is arranged on the side of the main body 11, and at least a part of the water inlet section 1042 is inclined towards the air dissolving cavity 102 in the direction from top to bottom, and the water inlet device 10 further comprises a flow monitoring unit 13, which is communicated with the water inlet section 1042 and at least a part of which is arranged below the water inlet section 1042. The flow monitoring unit 13 is used to measure the flow of the liquid flowing into the second flow channel 104. The flow of the liquid can be detected by the flow monitoring unit, and the space utilization can be improved. The flow monitoring unit 13 can measure the flow of the liquid in the tube according to the physical law of the fluid by using the flow form of the fluid, so as to understand the real-time flow of the liquid.

[0034] In some embodiments, the water inlet device 10 further comprises a bubbler 14, which is connected to the main body 11 and communicated with the liquid outlet 1013. The bubbler 14 further decomposes the liquid containing gas into liquid wrapped with ultra-micro bubbles.

[0035] Optionally, the liquid inlet 1012 is arranged on the lower part of the main body 11, and the liquid outlet is arranged on the lower part of the main body 11.

[0036] In some embodiments, the main body 11 further comprises an air exhaust cavity 105, which is separated from the air dissolving cavity 102, and the air exhaust cavity 105 is provided with a liner interface 1051, and the air inlet 1011 is communicated with the air exhaust cavity 105. By using the air exhaust cavity 105, the air inlet 1011 can conveniently intake air, avoiding the problem of air inlet 1011 blockage. In addition, when the liquid level is too high due to the failure of the water inlet device 10, the liquid can overflow from the air inlet 1011 to the liner interface 1051, thereby avoiding the problem of water inlet device 10 overflowing outward, improving the stability and safety of the water inlet device 10.

[0037] The air exhaust cavity 105 is further provided with a vent 1052, and the liner interface 1051 and the vent 1052 are distributed in the vertical direction. The liner interface 1051 can be arranged in the middle region of the main body 11, and the vent 1052 can be arranged in the top region of the main body 11. In the washing equipment with the water inlet device 10, the gas in the washing space of the washing equipment can enter the air exhaust cavity 105 through the liner interface 1051, and then be discharged from the main body 11 from the vent 1052 in the air exhaust cavity 105 from bottom to top, so as to realize the discharge of the gas. The gas outside the washing space can also enter the air exhaust cavity 105 through the vent 1052, and then enter the washing space through the liner interface 1051.

[0038] In addition, the vent 1052 and the air inlet 1011 are distributed in the horizontal direction, for example, Figure 1As shown, the vent 1052 penetrates the main body 11 and directly communicates with the external space, the air inlet 1011 is distributed away from the vent 1052, the vent 1052 communicates with the air inlet 1011 through the first one-way valve, and the air inlet 1011 can be open to one side of the vent 1052. In this way, external air can enter the exhaust cavity 105 through the vent 1052, and when the first one-way valve is open, the gas at the vent 1052 can flow to the air inlet 1011 and then flow into the air inlet channel. At the same time, when the exhaust cavity 105 needs to discharge gas, the gas in the exhaust cavity 105 is discharged out of the main body 11 from the vent 1052. The flow direction of the gas is not unique and can be selectively adjusted according to the working state of the washing equipment.

[0039] The exhaust cavity 105 is provided with a plurality of turbulence ribs 111 for blocking the gas in the exhaust cavity 105. The plurality of turbulence ribs 111 are distributed away from each other between the inner container interface 1051 and the vent 1052, and the extension direction of the turbulence rib 111 intersects the arrangement direction of the inner container interface 1051 and the vent 1052. The inner container interface 1051 and the vent 1052 are distributed along the up-down direction, and the extension direction of the turbulence rib 111 can be along the horizontal direction, i.e., the extension direction of the turbulence rib 111 is perpendicular to the up-down direction, or the up-down direction is non-perpendicular. The setting mode is various and selective.

[0040] The turbulence rib 111 can include at least one located in the middle region of the exhaust cavity 105 along the left-right direction, and can also include at least one located in the side region of the exhaust cavity 105 along the left-right direction. The turbulence rib 111 located in the middle region of the exhaust cavity 105 is configured as an arc-shaped structure, and the turbulence rib 111 located on both sides of the exhaust cavity 105 is configured as a linear structure. The two ends of the arc-shaped turbulence rib 111 extend toward the inner container interface 1051, and the middle part of the arc-shaped structure is away from the inner container interface 1051. The linear turbulence rib 111 is inclined downward in the direction toward the middle region. When the gas at the inner container interface 1051 flows from bottom to top, the plurality of turbulence ribs 111 can block the gas multiple times, so that the gas flows along a certain path, and the flow path of the gas is increased.

[0041] The main body 11 further forms a drainage flow channel 106, which is provided with a drainage inlet 1061 and a drainage outlet 1062, and the drainage flow channel 106 communicates with the exhaust cavity 105.

[0042] Specifically, the drain flow channel 106 is used for discharging liquid, and a part of the body portion 11 can be configured as the drain flow channel 106. When the washing device ends, the cleaned sewage in the washing space enters the drain flow channel 106 from the drain inlet 1061, and then is discharged to the outside of the body portion 11 through the drain pipe, so as to realize the discharge of the sewage. The drain flow channel 106 can be used as a central pipeline for discharging liquid, and the drain flow channel 106 is connected with the drain pump, which is used for pumping the liquid in the washing space.

[0043] The drain flow channel 106 is communicated with the exhaust cavity 105, so that the gas in the exhaust cavity 105 can enter the drain flow channel 106, and the gas pressure in the drain flow channel 106 can be supplemented to balance the pressure of the drain flow channel 106, so as to avoid the backflow of the drain flow channel 106. In this way, the gas in the exhaust cavity 105 can be recycled, the utilization rate of the gas is improved, and the anti-siphon of the drain is realized.

[0044] The drain inlet 1061 and the drain outlet 1062 can be arranged at the bottom of the body portion 11 and are spaced apart, so as to form a reverse U-shaped liquid flow path. In this way, the overall structure of the channel can be more compact, the space occupied can be smaller, and the integration degree of the whole can be improved.

[0045] The body portion 11 further forms a connecting channel 107, which is communicated with the exhaust cavity 105 and the drain flow channel 106. Specifically, the connecting channel 107 is located between the exhaust cavity 105 and the drain flow channel 106, and is communicated with the exhaust cavity 105 and the drain flow channel 106. The connecting channel 107 is located at the side of the exhaust cavity 105 away from the gas dissolving cavity 102, and can be arranged to extend vertically. In this way, the gas in the exhaust cavity 105 can be introduced into the drain flow channel 106 through the connecting channel 107.

[0046] Further, during the operation of the washing device, when the drain flow channel 106 discharges liquid, a negative pressure state can be formed in the drain flow channel 106, which can easily form a siphon effect and cause the backflow of the liquid discharged from the drain flow channel 106. In the embodiment, the gas is quickly introduced into the drain flow channel 106 through the connecting channel 107, so as to supplement the gas pressure in the drain flow channel 106, thereby preventing the backflow of the liquid in the drain process into the washing space.

[0047] In some embodiments, a second one-way valve 15 is arranged at the inlet of the connecting channel, and the second one-way valve 15 is configured to allow the gas in the exhaust cavity 105 to flow to the connecting channel 107 in one direction.

[0048] Specifically, the second one-way valve 15 is used for one-way conduction of the gas, such as Figure 1As shown, the second one-way valve 15 is arranged at the inlet of the communication passage of the connecting passage 107, is detachably connected to the top of the connecting passage 107, and is configured to be opened under the action of negative pressure at the inlet of the communication passage, i.e., when a pressure difference is formed between the inside of the connecting passage 107 and the outside space, so that the second one-way valve 15 is opened by the pressure difference, so that the gas is unidirectionally guided from the inner container interface 1051 to the connecting inlet.

[0049] Further, during the operation of the washing device, and when the drainage siphon effect is encountered, the second one-way valve 15 is opened by the larger external air pressure, the gas enters the exhaust cavity 105 from the air inlet 1052, and enters the connecting passage 107 through the second one-way valve 15, so as to balance the air pressure inside the drainage passage 106 and the outside space, thereby playing a role in preventing siphon.

[0050] Therefore, by arranging the second one-way valve 15, the gas can flow unidirectionally, and the air pressure of the drainage passage 106 and the outside space is balanced, thereby improving the stability of liquid discharge.

[0051] In some embodiments, the drainage passage 106 and the exhaust cavity 105 are located on the same side of the gas dissolving cavity 102, as shown in Figure 1 As shown, the drainage passage 106 and the exhaust cavity 105 are spaced apart in the up-down direction and are both located on the same side of the gas dissolving cavity 102, so that the drainage passage 106 and the exhaust cavity 105 occupy one side of the main body part 11, and the gas dissolving cavity 102 occupies the other side of the main body part 11, so that the integrated arrangement of the three can be achieved, and the occupied space of the gas dissolving cavity 102 is greater than that of the drainage passage 106 and the exhaust cavity 105, so that more space can be used for mixing of gas and liquid, so as to improve the gas-liquid mixture required in the washing process, and the main body part 11 has gas-liquid mixing function, exhaust function and drainage function at the same time, which is reasonable in arrangement, compact in structure, and can improve the cleaning function of the washing device.

[0052] The exhaust cavity 105 is located above the drainage passage 106, so that the liquid in the washing space can be discharged more quickly from the drainage passage 106, and the gas in the washing space can be discharged from the exhaust cavity 105, so as to realize the discharge of gas from the upper side and the discharge of liquid from the bottom, improve the exhaust efficiency and the drainage efficiency, and the two do not affect each other, thereby improving the working efficiency and stability of the washing device.

[0053] It should be noted that the air dissolving cavity 102 can be integrated with the drainage flow channel 106 to provide bubble water for the washing space and discharge the liquid in the washing space, the air dissolving cavity 102 can be integrated with the air exhaust cavity 105 to provide bubble water for the washing space and discharge the gas in the washing space, and the three can be integrated to provide bubble water for the washing space and discharge the gas and liquid in the washing space, and the setting modes are various and can be selectively set.

[0054] In combination with the foregoing, in some embodiments of the utility model, in the water inlet stage, the gas enters the air dissolving cavity 102 through the first one-way valve from the air inlet 1011, then the liquid with certain pressure flows into the water inlet device 10 through the liquid inlet 1012, is metered by the flow monitoring unit 13 first, then when the venturi pipe 1041, the gas in the air dissolving cavity 102 is taken into the air dissolving cavity 102 by the first flow channel 103 at the same time with water, the water mixes with the gas fully in the air dissolving cavity 102, after the gas-liquid mixture is mixed fully, the water flow wrapped with bubbles is discharged from the liquid outlet 1013, and the unsolved gas enters the venturi pipe 1041 through the first flow channel 103 at the top of the air dissolving cavity 102 to continue participating in the gas-liquid circulation process.

[0055] When siphon is generated in the water inlet stage, the first one-way valve at the position of the air inlet 1011 is opened due to the pressure difference between the outside gas pressure and the internal pressure of the cavity, the gas flows into the air dissolving cavity 102 to balance the pressure difference, thereby playing the anti-siphon role. The utility model meets the air inlet demand of the water inlet device 10, and also meets the anti-siphon function of the water inlet device 10 in the water inlet stage.

[0056] Optionally, the liquid inlet 1012 and the liquid outlet 1013 are arranged at the bottom of the main body part 11, and the liquid inlet 1012 and the liquid outlet 1013 are distributed with a spacing, so that the liquid flows into the liquid inlet channel, the venturi pipe 1041 and the air dissolving cavity 102 in turn from the bottom of the main body part 11 upwards, and the gas-liquid mixture in the air dissolving cavity 102 flows downwards to the bottom of the main body part 11, flows into the bubble generator 14 from the liquid outlet 1013, a reverse U-shaped flow path can be formed, so that the distribution of multiple channels is more compact, and the occupied space is smaller, and the integration degree is improved. The liquid outlet 1013 is arranged at the bottom of the equipment main body, the flow rate of the liquid can be improved by using the gravity of the liquid, the cleaning speed of the article is improved, the liquid containing bubbles can enter the washing space from the bottom of the equipment main body, the stability of the liquid flow is improved, the possibility of liquid splashing is reduced, and the cleaning neatness is improved.

[0057] According to the washing equipment of the embodiment of the utility model, including device main part and the water inlet device 10 of preceding described washing equipment, by using preceding described water inlet device 10, can utilize water inlet device 10 to water device main part, can to device main part gas and liquid and mixed fluid, form a large amount of liquid containing bubble, like this, can improve the washing characteristic of article, overall structure is more compact, function is more perfect, use effect is better, to improve the use experience of user. In addition, it can also have the technical effects of the water inlet device 10.
