TECHNICAL FIELD

[0001] The utility model relates to kitchen utensil technical field especially, relate to a kind of cleaning device and cooking utensil. BACKGROUND

[0002] The steaming and baking appliance is a kind of kitchen electrical appliances that combines the functions of steam and oven, which can simultaneously or separately perform steaming and baking. It can perform various cooking operations such as steaming, baking, baking, and barbecuing. By generating steam, low-temperature cooking can be achieved to retain the nutrients and moisture of food. Because it provides more cooking options and higher efficiency, this multifunctional appliance is becoming increasingly popular in modern kitchens. However, during use, various oil stains and dirt will inevitably accumulate in the cavity of the steaming and baking appliance, which requires the provision of appropriate cleaning tools to clean the steaming and baking appliance.

[0003] In related art, an automatic cleaning assembly is usually provided in the cavity of the steaming and baking appliance, which sprays water into the cavity of the steaming and baking appliance to clean the cavity of the steaming and baking appliance.

[0004] However, oil stains and other difficult-to-clean stains cannot be effectively cleaned by water spraying, and manual cleaning is still required, resulting in poor user experience. INVENTION CONTENTS

[0005] The utility model provides a kind of cleaning device and cooking utensil, the cleaning effect of this cleaning device is good, can improve user experience.

[0006] The utility model embodiment first aspect provides a kind of cleaning device, comprising:

[0007] The mixing valve includes a mixing chamber and a stirring assembly. The stirring assembly is rotatably arranged in the mixing chamber. An air inlet channel is formed on the stirring assembly and communicates with the mixing chamber.

[0008] The air inlet pipeline communicates with the air inlet channel. The air inlet pipeline is used to inject gas into the mixing chamber through the air inlet channel.

[0009] The water inlet pipeline communicates with the mixing chamber. The water inlet pipeline is used to inject liquid into the mixing chamber. Wherein,

[0010] When the stirring assembly rotates, the gas entering the mixing chamber from the air inlet channel mixes with the liquid in the mixing chamber to form a mixture. The mixture is used to clean the equipment to be cleaned.

[0011] The cleaning device in the embodiments of the present application can dissolve gas into water to form water with gas, for example, saturated water or supersaturated water, by arranging the gas inlet pipeline, the water inlet pipeline and the mixing valve. When the saturated water or supersaturated water impacts on an object, the gas is released from the water, which is commonly known as cavitation. Cavitation is a physical phenomenon that bubbles are formed in liquid when the flow velocity of the liquid increases or the pressure decreases to below the vapor pressure of the liquid. These bubbles then collapse rapidly, releasing gas, generating high-speed microjets and pressure shock waves, which can penetrate into every corner of the equipment to be cleaned, thereby effectively removing stubborn stains.

[0012] By arranging the mixing valve to include the mixing cavity and the stirring assembly, and rotating the stirring assembly in the containing cavity, the stirring assembly can promote the mixing of water and gas by mechanical stirring, reduce stratification, and ensure that the output mixture has consistent composition. In addition, in the gas-liquid mixing, the stirring assembly can help to break the bubbles into smaller sizes, thereby increasing the amount of dissolved gas in the liquid and increasing the effect of cavitation, thereby improving the cleaning effect of the cleaning device.

[0013] In a possible implementation, the stirring assembly includes a rotating part and a plurality of paddles.

[0014] The rotating part is provided with a first channel, and the paddle is provided with a second channel. One end of the first channel and one end of the second channel are in communication. The other end of the first channel is in communication with the gas inlet pipeline, and the other end of the second channel forms a gas outlet in communication with the mixing cavity. The first channel and the second channel constitute a gas inlet channel.

[0015] By arranging the stirring assembly to include the rotating part and the paddle, the rotating part can drive the paddle to rotate, improving the stability of the stirring assembly in the mixing valve. By arranging the first channel on the rotating part and the second channel on the paddle, and arranging the first channel and the second channel to constitute the gas inlet channel, the gas can be directly introduced into the interior of the paddle and uniformly distributed into the mixing cavity through the gas outlet. This ensures that the distribution of gas in the liquid is more uniform, improving the mixing efficiency. The gas directly enters the mixing area through the gas outlet on the paddle, can fully contact with the liquid during rotation, forms fine bubbles, increases the mixing effect of the gas and the liquid, and thereby increases the gas content in the liquid, to improve the cleaning effect.

[0016] In a possible implementation, the stirring assembly includes a rotating part and a plurality of paddles.

[0017] The rotating part is provided with a first channel and a third channel, the paddle is provided with a second channel, one end of the second channel and one end of the third channel are in communication with the first channel, the other end of the second channel and the other end of the third channel form gas outlets in communication with the mixing cavity, one end of the first channel is in communication with the gas inlet pipeline, and the first channel, the second channel and the third channel constitute a gas inlet channel.

[0018] In this way, the gas in the gas inlet pipeline can be introduced into the mixing cavity through the first channel and the second channel, and the first channel and the third channel. The gas flow into the mixing cavity can be increased, thereby improving the mixing uniformity, enhancing the turbulent effect of gas-liquid mixing, improving the overall mixing efficiency, and making the gas more effectively dispersed in the liquid. The gas entering the gas outlet of the gas inlet channel formed by the first channel and the second channel is more uniformly distributed in the mixing cavity due to the distribution of the gas outlet on the paddle, thereby improving the mixing efficiency and enabling the gas to fully contact the liquid during the rotation of the stirring assembly to form fine bubbles, thereby increasing the gas dissolution amount and the mixing effect.

[0019] In a possible implementation, the number of gas outlets on each paddle is multiple, and the multiple gas outlets are arranged on the paddle at intervals.

[0020] The number of gas outlets on the paddle near the bottom of the stirring assembly is greater than the number of gas outlets on the paddle near the top of the stirring assembly.

[0021] By arranging more gas outlets on the bottom of the paddle, the uniform distribution of the gas in the liquid can be ensured, especially in the bottom area, thereby promoting more uniform mixing effect. By introducing more gas at the bottom, the turbulent effect of gas-liquid mixing can be enhanced, the overall mixing efficiency can be improved, and the gas can be more effectively dispersed in the liquid. The high gas flow at the bottom helps to increase the gas dissolution amount in the liquid.

[0022] In a possible implementation, the gas inlet channel comprises a gas inlet port.

[0023] The gas inlet port of the gas inlet channel is in communication with the gas inlet pipeline, and the gas inlet port is located at the top of the stirring assembly.

[0024] By arranging the gas inlet port at the top of the stirring assembly, the pipeline design and installation process can be simplified, because the top position is generally easier to access the external gas inlet pipeline, thereby reducing the complex pipeline arrangement. The introduction of gas from the top can utilize the rotation and mixing effect of the stirring assembly to make the gas more uniformly distributed in the entire liquid, thereby enhancing the mixing effect.

[0025] In a possible implementation, the mixing cavity is provided with a connecting pipe, which extends from one end connected to the cavity wall of the mixing cavity to the bottom of the mixing cavity.

[0026] The end of the connecting pipe away from the cavity wall of the mixing cavity is rotatably connected to the air inlet of the air inlet channel and communicates with the air inlet.

[0027] By providing the connecting pipe, compared with directly connecting the stirring assembly to the cavity wall of the containing cavity, the assembly difficulty of the stirring assembly can be reduced, and the connection with the air inlet pipeline can be facilitated.

[0028] In a possible implementation, the mixing cavity is provided with a connecting portion;

[0029] The connecting portion extends from one end connected to the cavity wall of the mixing cavity to the top of the mixing cavity.

[0030] The end of the connecting portion away from the cavity wall of the mixing cavity is rotatably connected to the air inlet channel, the connecting portion and the stirring assembly form the air outlet of the air inlet channel, and the air outlet communicates with the mixing cavity.

[0031] In a possible implementation, in the direction from the bottom to the top of the stirring assembly, the width of at least part of the paddle gradually decreases.

[0032] The paddle comprises a curved portion, and the convex surface of the curved portion faces the rotation direction of the stirring assembly.

[0033] In this way, the shape of the paddle can be designed as a conical structure, and the conical paddle design can generate progressive fluid acceleration and diffusion effect during rotation, which helps to form more uniform flow and turbulence in the mixing cavity, and improves the mixing efficiency. The smaller top size makes the fluid receive greater shear force when entering the paddle area, and the wider bottom paddle can provide stronger stirring force to prevent solid particles or heavier components from settling at the bottom of the mixing container, ensuring the uniformity of the mixture. This design can effectively introduce gas into the liquid during the rotation of the paddle, increase the gas-liquid contact area and time, and improve the gas dissolution amount and mixing uniformity. The design of the curved portion enables the paddle to more effectively push the liquid, generate stronger turbulence and shear force, and thus improve the mixing effect. It can also increase the residence time of gas bubbles in the liquid, increase the contact area of gas and liquid, and improve the reaction efficiency, especially in gas-liquid reaction or dissolution process. The convex surface facing the rotation direction helps to better guide the fluid flow.

[0034] In a possible implementation, the mixing cavity is surrounded by a cooling cavity on the outside; wherein,

[0035] The cooling cavity is provided with a cooling component for cooling the mixture in the mixing cavity.

[0036] By arranging the cooling cavity outside the mixing cavity, the temperature of the liquid and gas in the mixing valve can be reduced, the mixing effect can be improved, the amount of dissolved gas in the liquid can be increased, the cavitation effect can be enhanced, the cleaning effect can be improved, and the user experience can be improved.

[0037] In a possible implementation, the mixing valve comprises a water inlet and a water outlet.

[0038] The water inlet is in communication with the water inlet pipeline, and the water inlet is located at the bottom of the mixing cavity.

[0039] In the direction from the bottom to the top of the mixing cavity, the water outlet is higher than the water inlet.

[0040] The water inlet is used for the water inlet pipeline to inject liquid into the mixing cavity, and the water outlet is used for the mixture to flow out.

[0041] By arranging the water inlet and the water outlet on the mixing valve, liquid can be conveniently input into the mixing cavity of the mixing valve, and the mixture in the mixing valve can also be discharged. By arranging the water inlet at the bottom of the mixing cavity, since the density of water is generally greater than that of gas, water entering from the bottom can flow downward naturally under the action of gravity, and gas entering from the top can flow upward naturally. The relative movement can enhance the mixing effect of the two. In addition, the water inlet located at the bottom of the mixing cavity can provide a certain pushing force on the paddle after the liquid enters the mixing valve from the water inlet, thereby pushing the paddle to rotate, so that the stirring assembly can rotate.

[0042] By arranging the water outlet to be higher than the water inlet, the gas-liquid mixture after mixing can be quickly discharged after stirring is completed, the residence time of gas bubbles in the valve body is reduced, and the aggregation of gas bubbles is prevented. After the gas enters from the top, gravity helps to push the gas downward into the liquid for mixing, and the water outlet located at the middle position can effectively discharge the mixed gas-liquid mixture, reducing the escape of un-mixed gas. Since the liquid enters from the bottom and is discharged from the middle, this design can reduce the risk of liquid backflow and prevent the stratification of the gas-liquid mixture in the valve body.

[0043] In a possible implementation, the cleaning device further comprises a water tank; wherein,

[0044] The water tank is connected with the water inlet pipeline, and a cooling module is arranged between the water tank and the water inlet pipeline, and the cooling module is used for cooling the liquid entering the water inlet pipeline.

[0045] By setting the cooling module between the water tank and the water inlet pipeline, the liquid entering the mixing valve can be cooled, thereby improving the dissolution amount of the gas in the liquid, improving the mixing effect, and further improving the cleaning effect.

[0046] In a possible implementation, the cleaning device further comprises a gas source; wherein,

[0047] The gas source is in communication with the gas inlet pipeline;

[0048] A pressure control valve is arranged between the gas source and the gas inlet pipeline, and the pressure control valve is used to control the pressure of the gas entering the gas inlet pipeline.

[0049] By setting the gas source, the gas inlet pipeline can be provided with gas, and by setting the pressure control valve, the gas entering the mixing chamber can be given a certain pressure, so that the gas and the liquid can be fully mixed, and the dissolution amount of the gas in the liquid can be improved.

[0050] In a possible implementation, the cleaning device further comprises a water outlet pipeline, and the water outlet pipeline is in communication with the water outlet of the mixing valve;

[0051] One end of the water outlet pipeline, which is away from the water outlet, is connected with a spraying device, and the spraying device is used to spray the mixture formed in the mixing valve to the equipment to be cleaned to clean the equipment to be cleaned.

[0052] In a possible implementation, the water outlet pipeline comprises a throttle valve; wherein,

[0053] The throttle valve is connected with the spraying device.

[0054] In this way, the spraying pressure of the spraying device can be increased, the impact force of the sprayed liquid column can be improved, and the cleaning effect can be improved.

[0055] In a possible implementation, the spraying device is a rotatable structure; wherein,

[0056] The spraying device can rotate by 360 degrees relative to the water outlet pipeline.

[0057] In this way, the cleaning range can be expanded, and the cleaning effect can be improved.

[0058] In a possible implementation, the spraying device is a telescopic structure; wherein,

[0059] The spraying device can move in the axial direction of the water inlet pipeline.

[0060] In this way, the cleaning range can be expanded, and the cleaning effect can be improved.

[0061] In a possible implementation, the cleaning device further comprises a water collecting part and a water return pipeline; wherein,

[0062] One end of the water return pipeline is in communication with the water collecting part, and the other end is in communication with the mixing valve;

[0063] The water collecting part is used for collecting sewage after cleaning, and the water return pipeline is used for recycling sewage;

[0064] A first filter is arranged between the water return pipeline and the water collecting part, and the first filter is used for filtering sewage collected from the water collecting part.

[0065] In a possible implementation, a second filter and a backflow pump are arranged on the water return pipeline; wherein,

[0066] The backflow pump is arranged between the second filter and the mixing valve;

[0067] The second filter is used for filtering liquid in the water return pipeline, and the backflow pump is used for sucking liquid in the water return pipeline back to the mixing valve.

[0068] In this way, the cleanliness of liquid in the water return pipeline can be improved, and water resources can be reused, thereby saving resources.

[0069] The second aspect of the embodiment of the application provides a cooking utensil, comprising an inner container and the cleaning device of any one of the first aspect.

[0070] The cleaning device is used for cleaning the inner container.

[0071] The cooking utensil provided by the embodiment of the application can clean the inner container by using the cleaning assembly after cooking. Due to the cleaning device, the gas can be dissolved in water by arranging the air inlet pipeline, the water inlet pipeline and the mixing valve, so as to form water containing gas, for example, saturated water or supersaturated water. When the saturated water or supersaturated water impacts an object, the gas is released from the water, and cavitation is generated. Cavitation is a physical phenomenon. When the flow velocity of liquid increases or the pressure decreases to be lower than the vapor pressure of the liquid, bubbles are formed in the liquid. These bubbles then collapse rapidly, release gas, generate high-speed microjet and pressure shock wave, and can penetrate into every corner of the equipment to be cleaned, thereby effectively removing stubborn stains.

[0102] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0103] The cleaning device and the cooking appliance in the embodiments of the present application will be further described below in conjunction with the drawings.

[0104] Figure 1 is a schematic view of a frame structure of a cooking appliance provided in the embodiments of the present application.

[0105] As shown in Figure 1 , the cooking appliance 200 provided in the embodiments of the present application can include an inner container 210 and a cleaning device 100 arranged in the inner container 210, wherein the cleaning device 100 is used to clean the inner container 210. Exemplarily, part of the structure of the cleaning device 100 can be located at the top of the inner container 210, and part of the structure is located in the inner container 210, thereby performing the cleaning work on the inner container 210.

[0106] As shown in Figure 1 , part of the structure of the cleaning device 100 is located at the top of the inner container 210, and the inner container 210 includes a side wall, and a cooking space 220 surrounded by a plurality of side walls. When in use, food and the like can be placed in the cooking space 220 to cook the food.

[0107] The cooking appliance 200 in the embodiments of the present application can be an oven, a steamer, a steaming and baking appliance, etc. In the embodiments of the present application, the specific type of the cooking appliance 200 is not further limited.

[0108] The cooking appliance 200 in the embodiments of the present application can realize self-cleaning by arranging the cleaning device 100, without manual cleaning, thereby improving the user experience.

[0109] The cleaning device 100 will be described in detail below in conjunction with the drawings.

[0110] Figure 2 is a top view of a cooking appliance 200 provided in the embodiments of the present application.

[0111] As shown in Figure 2As shown, the cleaning device 100 can include a water inlet pipeline 10, an air inlet pipeline 50 and a mixing valve 30. The mixing valve 30 is internally provided with a mixing chamber 32, the water inlet pipeline 10 and the air inlet pipeline 50 are both in communication with the mixing chamber 32, the water inlet pipeline 10 is used for injecting liquid (for example, water or water containing cleaning liquid) into the mixing chamber 32, the air inlet pipeline 50 is used for injecting gas into the mixing chamber 32, and the mixing chamber 32 is used for mixing the liquid and the gas to form a mixture containing water with gas, which can be saturated water, supersaturated water or unsaturated water.

[0112] For example, the mixing valve 30 can be connected with a spraying device 60 (see Figure 3 as shown) through a water outlet pipeline 40, and the spraying device 60 is used for spraying and cleaning the equipment to be cleaned.

[0113] The cleaning device 100 in the embodiment of the present application can dissolve gas into water by setting the air inlet pipeline 50, the water inlet pipeline 10 and the mixing valve 30, to form water with gas, for example, saturated water or supersaturated water. When the saturated water or the supersaturated water impacts on an object, the gas is released from the water, which is commonly known as "cavitation". Cavitation is a physical phenomenon that gas bubbles are formed in the liquid when the flow speed of the liquid increases or the pressure decreases to below the vapor pressure of the liquid. These gas bubbles will then collapse rapidly, releasing gas, generating high-speed micro-jet and pressure shock wave, which can penetrate into every corner of the equipment to be cleaned, and thus can effectively remove stubborn stains.

[0114] Continuing to refer to Figure 2 as shown, the cleaning device 100 can further include a water tank 81, the water tank 81 is connected with the water inlet pipeline 10, and the water tank 81 is used for supplying water to the water inlet pipeline 10. A cooling module 20 is arranged between the water tank 81 and the water inlet pipeline 10, and the cooling module 20 is used for cooling the liquid entering the water inlet pipeline 10.

[0115] By arranging the cooling module 20 between the water tank 81 and the water inlet pipeline 10, the liquid entering the mixing valve 30 can be cooled, so as to increase the amount of dissolved gas in the liquid, improve the mixing effect, and thus improve the cleaning effect.

[0116] The cleaning device 100 provided by the embodiment of the present application can further include a gas source 82, wherein the gas source 82 is in communication with the air inlet pipeline 50, and the gas source 82 is used for supplying gas to the air inlet pipeline 50. A pressure control valve 51 can be further arranged between the gas source 82 and the air inlet pipeline 50, and the pressure control valve 51 is used for controlling the pressure of the gas entering the air inlet pipeline 50.

[0117] The gas source 82 is arranged to provide gas to the gas inlet pipeline 50, and the pressure control valve 51 is arranged to provide the gas entering the mixing valve 30 with a certain pressure, so that the gas and the liquid can be fully mixed, and the amount of dissolved gas in the liquid is improved.

[0118] In a possible implementation, the water outlet pipeline 40 comprises a throttle valve 41, wherein the throttle valve 41 is connected to the spraying device 60, so that the spraying pressure of the spraying device 60 is increased, the impact force of the sprayed liquid column is improved, and the cleaning effect is improved.

[0119] Figure 3 is another angle of the structure of the cooking utensil according to an embodiment of the present application.

[0120] As shown in Figure 3 , the spraying device 60 is arranged at the top of the inner container 210, and the water spraying end of the spraying device 60 faces the cooking space 220 of the inner container 210, so as to clean the cooking space 220.

[0121] For example, the spraying device 60 is a rotatable structure, wherein the spraying device 60 can rotate by 360° relative to the water outlet pipeline 40. In this way, the cleaning range is expanded, and the cleaning effect is improved. In a possible implementation, the spraying device 60 can also be a telescopic structure, wherein the spraying device 60 can move in the axial direction of the water inlet pipeline 10. In this way, the cleaning range is expanded, and the cleaning effect is improved.

[0122] It should be noted that, in the embodiments of the present application, the rotating structure and the telescopic structure of the spraying device 60 are not limited further, as long as they can rotate by 360° and can be telescopic.

[0123] In a possible implementation, as shown in Figure 1 and Figure 2 , the cleaning device 100 can further comprise a water collecting part 72 and a water return pipeline 71, wherein one end of the water return pipeline 71 is in communication with the water collecting part 72, and the other end is in communication with the mixing valve 30. The water collecting part 72 is used to collect sewage after cleaning, and the water return pipeline 71 is used to recycle the sewage. A first filter 722 is arranged between the water return pipeline 71 and the water collecting part 72, and the first filter 722 is used to filter the sewage collected from the water collecting part 72.

[0124] For example, as shown in Figure 4 , the water collecting part 72 is recessed from the outside to the middle, so that the sewage in the cooking space 220 can be collected conveniently. A plurality of strip-shaped through holes 721 are arranged on the water collecting part 72, so as to facilitate the collection of the sewage from the water collecting part 72. The first filter 722 can be arranged at the recessed part of the water collecting part 72, and is used to filter the sewage for the first time.

[0125] It should be noted that the first filter 722 is mainly used to filter large particles of dirt.

[0126] Figure 5 is a bottom view of the cooking utensil provided by the embodiment of the utility model.

[0127] As Figure 5 shown, the return water pipeline 71 is provided with a second filter 73 and a return pump 74. The return pump 74 is arranged between the second filter 73 and the mixing valve 30, the second filter 73 is used to filter the liquid in the return water pipeline 71, and the return pump 74 is used to return the liquid in the return water pipeline 71 to the mixing valve 30.

[0128] By arranging the second filter 73, the cleanliness of the liquid in the return water pipeline 71 can be improved, and the water resource can be reused, thereby saving resources.

[0129] Exemplarily, the second filter 73 can further include a water level detection device (not shown in the figure), which is used to detect whether there is water in the water collecting part 72. The detection device can be connected with the return pump 74, and when there is water in the water collecting part 72, the return pump 74 can be controlled to work to return the water in the return water pipeline 71 to the mixing valve 30, and the mixing operation is repeated.

[0130] It should be noted that in order to ensure that the mixed liquid can provide effective cleaning effect, the solubility of carbon dioxide needs to reach 3.0-4.0V / V. However, under normal temperature and pressure (25 degrees Celsius, one standard atmosphere), the saturated solubility of carbon dioxide in water is only 0.759V / V. 2 .

[0131] When using the cleaning device 100, the water tank 81 can be adjusted first, so that the output pressure is 2-5kg / cm 2 , and the temperature of the water is 0℃ to 5℃, then the carbon dioxide is output from the gas source 82 (carbon dioxide bottle) through the pressure control valve 51. The carbon dioxide and water are fully mixed in the mixing valve 30, so that the carbon dioxide is dissolved in the water to generate carbonated water, which is stored in the pressure stabilizing storage tank 42, and then the output flow of the carbonated water is controlled and adjusted through the throttle valve 41.

[0132] In addition, it should be noted that in the water outlet pipeline 40, a plurality of mixing valves 30 can be arranged to improve the mixing effect.

[0133] Of course, in other embodiments, the water temperature and water pressure can also be controlled within other ranges, and the specific values of the water temperature and water pressure are not limited further in the embodiments of the present application.

[0134] As shown in Figure 6 , the cleaning device 100 works, and gas can be introduced into the gas inlet pipeline 50 through the gas source 82, and the gas can be carbon dioxide. Water is usually provided by a water tank 81 (such as a water purification tank 81 or a water purifier), and is adjusted to an appropriate pressure and temperature by the cooling module 20 and the booster pump 21. Then the gas and the liquid are mixed by the mixing valve 30, and then enter the water outlet pipeline 40, and finally reach the spraying device 60.

[0135] The cleaning device provided in the embodiments of the present application has a remarkable cleaning effect, can not use or reduce the use of a detergent, reduces chemical residues and environmental impact. Using cavitation cleaning can reduce the need for secondary or multiple flushing, simplifying the cleaning process. Reducing the use of chemical cleaning agents is more environmentally friendly.

[0136] The cleaning device 100 in the embodiments of the present application cleans by cavitation, compared with the traditional flushing system, cavitation cleaning does not need long time flushing, thereby saving water resources.

[0137] The mixing valve 30 will be described in detail below with reference to the accompanying drawings.

[0138] Figure 7 is a structure schematic view of a mixing valve of a cleaning device provided by the embodiments of the present application.

[0139] Figure 8 is a cross-sectional structure schematic view of the structure shown in Figure 7 .

[0140] As shown in Figure 7 , the mixing valve 30 includes a mixing chamber 32 and a stirring assembly 35, and the stirring assembly 35 is rotatably arranged in the mixing chamber 32.

[0141] As shown in Figure 8 , the stirring assembly 35 is formed with an air inlet channel (not shown in the figure) in communication with the mixing chamber 32. When the stirring assembly 35 rotates, the gas entering the mixing chamber 32 from the air inlet channel mixes with the liquid in the mixing chamber 32 to form a mixture, and the mixture is used to clean the equipment to be cleaned.

[0142] For example, the liquid entering the mixing chamber 32 can push the stirring assembly 35 to rotate, and in the rotation process of the stirring assembly 35, the liquid mixes with the gas entering the mixing chamber 32 to form a mixture, and the mixture is used to clean the equipment to be cleaned.

[0143] By setting the mixing valve 30 to include the mixing chamber 32 and the stirring assembly 35, and rotating the stirring assembly 35 in the containing chamber, the stirring assembly 35 can promote the mixing of water and gas by mechanical stirring, reduce stratification, and ensure that the output mixture has consistent composition. In addition, in the gas-liquid mixing process, the stirring assembly 35 can help break up the gas bubbles into smaller sizes, thereby increasing the amount of gas dissolved in the liquid and increasing the cavitation effect, thereby improving the cleaning effect of the cleaning device.

[0144] In combination Figure 7 and Figure 8 As shown in FIG. 7, the mixing valve 30 can include a water inlet 341 and a water outlet 342. The water inlet 341 can be used to communicate with the water inlet pipeline 10, and the water inlet 341 is located at the bottom of the mixing chamber 32. In the direction (z direction) from the bottom to the top of the mixing chamber 32, the water outlet 342 is higher than the water inlet 341. The water inlet 341 is used for the water inlet pipeline 10 to inject liquid into the mixing chamber 32, and the water outlet 342 is used for the mixture to flow out. For example, the water outlet 342 can communicate with the water outlet pipeline 40, and then be connected with the spraying device.

[0145] By setting the water inlet 341 and the water outlet 342 on the mixing valve 30, it is convenient to input liquid into the mixing chamber 32 of the mixing valve 30, and also to discharge the mixture in the mixing valve 30. By setting the water inlet 341 at the bottom of the mixing chamber, since the density of water is generally greater than that of gas, water entering from the bottom can flow naturally downward by gravity, while gas entering from the top can flow naturally upward. This relative movement can enhance the mixing effect of the two. In addition, the water inlet 341 located at the bottom of the mixing chamber can provide a certain pushing force to the paddle 352 after the liquid enters the mixing valve 30 from the water inlet 341, thereby pushing the paddle to rotate, so that the stirring assembly 35 can rotate.

[0146] By setting the water outlet 342 higher than the water inlet 341, the gas-liquid mixture after mixing can be quickly discharged after stirring is completed, reducing the residence time of gas bubbles in the valve body and preventing gas bubbles from gathering. After the gas enters from the top, gravity helps to push the gas downward into the liquid for mixing, and the water outlet 342 located near the middle position can effectively discharge the mixed gas-liquid mixture, reducing the escape of un-mixed gas. Since the liquid enters from the bottom and is discharged from the middle, this design can reduce the risk of liquid backflow and prevent stratification of the gas-liquid mixture in the valve body.

[0147] Continuing to participate Figure 8 As shown in FIG. 8, the stirring assembly 35 includes a rotating part 351 and a plurality of paddles 352. By setting the stirring assembly 35 to include the rotating part 351 and the paddles 352, the rotating part 351 can drive the paddles 352 to rotate, thereby improving the stability of the stirring assembly 35 in the mixing valve 30.

[0148] In some embodiments, the rotating part 351 is provided with a first channel 3511 and a third channel 3512, the paddle 352 is provided with a second channel 3522, one end of the second channel 3522 and one end of the third channel 3512 are both in communication with the first channel 3511, the other end of the second channel 3522 and the other end of the third channel are both formed into a gas outlet 3521 in communication with the mixing cavity 32, one end of the first channel 3511 is in communication with the gas inlet pipeline 50, and the first channel 3511, the second channel 3522 and the third channel 3512 constitute a gas inlet channel.

[0149] For example, the third channel 3512 can be a through-hole structure provided on the rotating part 351 and in communication with the mixing cavity 32, which can be located at the bottom end of the first channel 3511 or at the middle of the first channel 3511. In the embodiments of the present application, the structure and the setting position of the third channel 3512 are not further limited.

[0150] In this way, the gas in the gas inlet pipeline 50 can be introduced into the mixing cavity 32 through the first channel 3511 and the second channel 3522, and the first channel 3511 and the third channel 3512. The gas flow into the mixing cavity 32 can be increased, thereby improving the mixing uniformity, enhancing the turbulent effect of gas-liquid mixing, improving the overall mixing efficiency, and making the gas more effectively dispersed in the liquid. The gas entering the gas outlet 3521 of the gas inlet channel formed by the first channel 3511 and the second channel 3522 can be more uniformly distributed in the mixing cavity 32 due to the distribution of the gas outlet 3521 on the paddle 352, thereby improving the mixing efficiency and allowing the gas to fully contact the liquid during the rotation of the stirring assembly 35 to form fine bubbles, increase the amount of dissolved gas and improve the mixing effect.

[0151] In a possible implementation, the gas inlet channel can include a gas inlet 343. The gas inlet 343 of the gas inlet channel is in communication with the gas inlet pipeline 50, and the gas inlet 343 is located at the top of the stirring assembly 35.

[0152] By setting the gas inlet 343 at the top of the stirring assembly 35, the pipeline design and installation process can be simplified, as the top position is generally easier to access the external gas inlet pipeline 50, reducing the complex pipeline arrangement. Introducing gas from the top can utilize the rotation and mixing effect of the stirring assembly 35 to make the gas more uniformly distributed in the entire liquid, thereby enhancing the mixing effect.

[0153] In one possible implementation, the mixing chamber 32 is provided with a connecting pipe 36 extending from a connecting end to the bottom of the mixing chamber 32. The end of the connecting pipe 36 away from the mixing chamber 32 is rotatably connected to the air inlet 343 of the air inlet passage and communicates with the air inlet 343. The connecting pipe 36 can be integrally formed on the mixing chamber 32.

[0154] By providing the connecting pipe 36, the assembly of the stirring assembly 35 can be facilitated, and the air inlet passage can be connected to the stirring assembly 35 more easily.

[0155] Continuing to refer to Figure 8 As shown, the mixing chamber 32 is provided with a connecting portion 37. The connecting portion 37 extends from a connecting end to the top of the mixing chamber 32. The end of the connecting portion 37 away from the mixing chamber 32 is rotatably connected to the air inlet passage, and the connecting portion 37 and the stirring assembly 35 form an air outlet 3521 of the air inlet passage, which communicates with the mixing chamber 32.

[0156] As an example, the outer wall 33 of the mixing chamber can include a side wall 331 and a bottom wall 332 (see Figure 8 As shown, the connecting portion 37 can be provided on the bottom wall 332. For example, the connecting portion 37 can be integrally formed on the bottom wall 332.

[0157] As shown in Figure 9 The stirring assembly 35 can include a rotating portion 351 and a plurality of paddles 352. The plurality of paddles 352 are arranged at intervals along the circumference of the rotating portion 351, and the rotating portion 351 is configured to rotate the plurality of paddles 352 when the rotating portion 351 rotates. Each of the plurality of paddles 352 is provided with a plurality of air outlets 3521 arranged at intervals, and the air outlets 3521 communicate with the mixing chamber 32. The number of the air outlets 3521 on the paddles 352 near the bottom of the stirring assembly 35 is greater than the number of the air outlets 3521 on the paddles 352 near the top of the stirring assembly 35.

[0158] By providing multiple gas outlets 3521 on the paddle 352, in an example, the gas outlets 3521 on the paddle 352 extend through the paddle 352, that is, the fluid can pass through the gas outlets 3521 from one side of the paddle 352 to the other side of the paddle 352. This can allow the mixture in the mixing chamber 32 to pass through the paddle 352 as the paddle 352 rotates, thereby creating more complex flow paths and turbulence. Such turbulence can significantly improve the mixing efficiency of the gas and liquid. The design of the gas outlets 3521 increases the contact area and contact time of the fluid with the paddle 352, promoting interaction between the gas and liquid, helping to mix more quickly and evenly. When the gas passes through the gas outlets 3521 on the paddle 352, the gas bubbles can be broken up into smaller sizes. This bubble refinement helps to increase the amount of gas dissolved and the degree of dispersion of the gas in the liquid.

[0159] By providing more gas outlets 3521 at the bottom of the paddle 352, uniform distribution of gas in the liquid can be ensured, especially in the bottom region, promoting more uniform mixing effect. By introducing more gas at the bottom, the turbulent effect of gas-liquid mixing can be enhanced, improving the overall mixing efficiency and allowing the gas to be dispersed more effectively in the liquid. The high gas flow at the bottom helps to increase the amount of gas dissolved in the liquid.

[0160] In some embodiments, the number of paddles 352 can be two, three, four or more, which can be determined according to the size of the mixing chamber 32, and the number of paddles 352 is not limited in the embodiments of the present application.

[0161] Continuing to refer to Figure 9 As shown, the width of at least part of the paddle 352 gradually decreases in the direction from the bottom to the top of the stirring assembly. That is, the size of the paddle 352 at the end close to the top of the mixing valve 30 is small, so that the paddle 352 can have a conical structure.

[0162] The conical paddle 352 design can produce progressive fluid acceleration and diffusion effects when rotating, helping to form more uniform flow and turbulence in the mixing chamber 32 and improve mixing efficiency. The smaller top size allows the fluid to experience greater shear force when entering the paddle 352 area, while the larger bottom size can effectively push and mix more fluid, ensuring that the fluid in the entire mixing chamber 32 is fully mixed. This design can effectively introduce gas into the liquid as the paddle 352 rotates, increasing the gas-liquid contact area and time, and improving the amount of gas dissolved and mixing uniformity.

[0163] Exemplarily, the paddle 352 can include a curved portion 3523, and a convex surface of the curved portion 3523 faces a rotation direction of the stirring assembly 35. That is, the paddle 352 can be a curved structure. In the z direction, the paddle 352 includes at least one arc-shaped curved portion 3523, so that the surface of the paddle 352 is smooth, and the resistance is reduced.

[0164] In addition, by setting the paddle 352 as a curved structure, the curved paddle 352 can generate a complex flow path and a turbulent flow effect during rotation, which helps to improve the mixing efficiency of the gas and the liquid and ensure the uniformity of the mixture. The curved structure can increase the contact time and the contact area of the fluid on the surface of the paddle 352, thereby promoting more sufficient mixing and improving the amount of gas dissolved in the liquid. The curved paddle 352 can increase the dispersion and the contact area of the gas in the liquid, promote the dissolution and uniform distribution of the gas, and improve the mixing effect.

[0165] Of course, in other embodiments, the paddle 352 can also have other shapes, for example, a structure with the same size of the paddle 352 up and down, such as Figure 10 As shown, the paddle 352 is a quadrilateral plate structure. In the embodiments of the present application, the shape of the paddle 352 is not limited further.

[0166] By setting the paddle 352 as a plate structure, the structure of the paddle 352 can be simplified, the processing difficulty is reduced, and the cost is further reduced. The plate-shaped paddle 352 can generate a large shear force during rotation, which helps to improve the mixing efficiency and uniformity. The plate-shaped paddle 352 can guide the fluid to flow along a specific path in the mixing cavity 32, reduce the dead zone and the area with poor flow, and ensure that the fluid in the entire mixing cavity 32 is fully mixed.

[0167] It should be noted that the paddle 352 can be a solid structure or a hollow structure.

[0168] Figure 11 is a cross-sectional structure schematic of a stirring assembly 35 of a mixing valve 30 of a cleaning device provided by the embodiments of the present application Figure 1 . Figure 11 is a cross-sectional structure schematic of a stirring assembly 35. In the figure, the straight line with an arrow represents the gas flow direction of the air inlet channel.

[0169] In a possible implementation manner, as Figure 11As shown, the stirring assembly 35 comprises a rotating part 351 and a plurality of paddles 352. The rotating part 351 is provided with a first channel 3511, and the paddles 352 are provided with a second channel 3522. One end of the first channel 3511 and one end of the second channel 3522 are communicated, the other end of the first channel 3511 is communicated with the gas inlet pipeline 50, and the other end of the second channel 3522 forms a gas outlet 3521 communicated with the mixing cavity 32. The first channel 3511 and the second channel 3522 constitute a gas inlet channel.

[0170] For example, the paddle 352 can be a hollow structure, and at least one of the two opposite side walls 331 forming the hollow structure is provided with the gas outlet 3521 to communicate the second channel 3522 with the mixing cavity 32.

[0171] In some embodiments, the gas outlet 3521 can pass through one side of the two opposite side walls 331 forming the hollow structure of the paddle 352 (such as Figure 11 As shown, the gas outlets 3521 on different paddles 352 are all arranged on the same side, so that the gas flow formed by the gas flow channel flows in one direction, improves the dynamic performance of the stirring assembly 35, and reduces energy consumption.

[0172] Of course, in other embodiments, the gas outlet 3521 can also pass through the two opposite side walls forming the hollow structure (such as Figure 12 As shown, in the embodiments of the present application, the arrangement mode of the gas outlet 3521 is not limited.

[0173] By arranging the first channel 3511 on the rotating part 351 and the second channel 3522 on the paddle 352, and arranging the first channel 3511 and the second channel 3522 to constitute a gas inlet channel, the gas can be directly introduced into the interior of the paddle 352 and uniformly distributed into the mixing cavity 32 through the gas outlet 3521 on the paddle 352. This can ensure that the distribution of the gas in the liquid is more uniform, improve the mixing efficiency. The gas directly enters the mixing area through the gas outlet 3521 on the paddle 352, can fully contact with the liquid during rotation, forms fine bubbles, increases the mixing effect of the gas and the liquid, and then increases the gas content in the liquid, to improve the cleaning effect.

[0174] Of course, in some other embodiments, two gas inlet channels (such as Figure 8 As shown, one gas inlet channel is the first channel 3511 and the third channel 3512, and the other gas inlet channel can be a channel formed by connecting the first channel 3511 and the second channel 3522. In the embodiments of the present application, the gas inlet channel is not limited.

[0175] For example, the gas inlet pipeline 50 can be arranged on the rotating part 351 (such as Figure 13As shown, the outer side of the mixing cavity 32 can also be provided with a cooling cavity 31. The cooling cavity 31 is provided with a cooling component for cooling the mixture in the mixing cavity 32.

[0176] By providing the cooling cavity 31 outside the mixing cavity 32, the temperature of the liquid and gas in the mixing valve 30 can be reduced, the mixing effect is improved, the amount of gas dissolved in the liquid is increased, the cavitation effect is enhanced, and the cleaning effect is improved, thereby improving the user experience.

[0177] It should be noted that the gas provided by the gas source 82 can be carbon dioxide. Table 1 shows the solubility of carbon dioxide in water at different temperatures. Table 2 shows the solubility of carbon dioxide in water at different temperatures and pressures.

[0178] Table 1

[0179]

[0180] Table 2

[0181]

[0182] As shown in Table 1 and Table 2, the solubility of carbon dioxide in water gradually increases with the decrease of temperature under the same atmospheric pressure, that is, the lower the temperature, the greater the solubility. Therefore, by reducing the temperature of the liquid, the solubility of carbon dioxide in water can be increased, the content of gas in water can be increased, the cavitation effect can be improved, and the cleaning effect can be improved.

[0183] In addition, the solubility of carbon dioxide in water is different under different pressures at the same temperature, so the solubility of carbon dioxide in water can be controlled according to the pressure and temperature.

[0184] It should be noted that in order to ensure that the mixed liquid can provide effective cleaning effect, the solubility of carbon dioxide needs to reach 3.0-4.0V / V. However, under normal temperature and pressure (25 degrees Celsius, one standard atmospheric pressure), the saturated solubility of carbon dioxide in water is only 0.759V / V. Therefore, in order to increase the content of carbon dioxide in water, the water temperature needs to be maintained at 0℃ to 5℃, and the water pressure needs to be controlled at 2-5kg / cm 2 .

[0185] It should be noted that V / V is the volume ratio (Volume / Volume), which refers to the volume of gas dissolved in a certain volume of liquid. "2-5kg / cm 2 " refers to 2 to 5 kilograms of force per square centimeter.

[0186] It should be noted that in the embodiments of the present application, the type of cooling component is not limited, for example, it can be a cooling liquid, a refrigerant or a refrigeration device, etc.

[0187] The cleaning device provided in the embodiments of the present application can dissolve gas into water by arranging the gas inlet pipeline 50, the water inlet pipeline and the mixing valve 30 to form water with gas, for example, saturated water or supersaturated water. When the saturated water or supersaturated water impacts on an object, the gas is released from the water, which is commonly known as "cavitation". Cavitation is a physical phenomenon that bubbles are formed in liquid when the flow velocity of the liquid increases or the pressure decreases to below the vapor pressure of the liquid. These bubbles then collapse rapidly to release gas, generate high-speed microjet and pressure shock wave, which can penetrate into every corner of the equipment to be cleaned, thereby effectively removing stubborn stains. By arranging the mixing valve 30 to include the mixing chamber 32 and the stirring assembly 35, and rotating the stirring assembly 35 in the containing chamber, the stirring assembly 35 can promote the sufficient mixing of water and gas by mechanical stirring, reduce the stratification phenomenon, and ensure that the mixture output has consistent composition. In addition, in the gas-liquid mixing, the stirring assembly 35 can help to break the bubbles into smaller sizes, thereby increasing the amount of dissolved gas in the liquid.

[0188] By arranging the cooling chamber 31 outside the mixing valve 30, the mixing effect of the mixing valve 30 can be improved, the amount of dissolved gas in the liquid can be increased, the content of gas in the liquid can be further increased, and the "cavitation" effect can be enhanced, thereby improving the cleaning effect of the cleaning device.
