[0004] This utility model provides a bubble generating system for a washing appliance. The bubble generating system includes an electrolytic air module and a bubble generating module. The bubble generating module includes an air inlet, a water inlet, and a water outlet. The electrolytic air module is connected to the air inlet, the water outlet is connected to the washing chamber of the washing appliance, and the water inlet is connected to a water source. The electrolytic air module electrolyzes air to generate gas that is introduced into the bubble generating module. The bubble generating module mixes the gas with water to form bubbled water, and introduces the bubbled water into the washing chamber through the water outlet.

[0005] The aforementioned bubble generating system can use the gas generated by the electrolysis of air by the air electrolysis module to mix with water to form bubble water. The bubble water containing the gas can be introduced into the washing chamber to clean items. Since the bubble water containing the gas has a certain cleaning ability, it can achieve consumable-free cleaning or reduce cleaning consumables for washing appliances under light contaminants, thereby reducing the long-term use cost of washing appliances.

[0007] In the above embodiments, the gas pressure input from the electrolytic air module to the bubble generating module can be increased, thereby allowing more bubbles to be introduced into the water, which in turn improves the cleaning ability of the bubble water to a certain extent.

[0008] In some embodiments, the bubble generating module includes a first bubble generating component, which includes a bubble generating cavity and a bubble tube. The bubble generating cavity is provided with a water inlet and is used to introduce water through the water inlet. The bubble tube is provided with an air inlet and an air outlet. The size of the air outlet is smaller than the size of the air inlet. The air inlet is used to introduce gas, and the air outlet is used to introduce gas bubbles into the bubble generating cavity, so that the gas bubbles and water mix in the bubble generating cavity to form bubble water.

[0009] In the above embodiments, the structure of the bubble generating module that produces gas-containing bubble water is simple.

[0010] In some embodiments, the bubble generating module includes a second bubble generating component, and the first bubble generating component is connected to the washing chamber via the second bubble generating component; the second bubble generating component is used to reduce the size of the bubbles in the bubble water.

[0011] In the above embodiments, the second bubble generating component can reduce the size of the bubbles in the sparkling water, thereby improving the cleaning ability of the sparkling water to a certain extent.

[0013] In the above embodiments, the bubbles in the bubble water can be made smaller by spiral motion.

[0014] In some embodiments, the second bubble generating assembly includes a second processing chamber having a variable diameter flow channel. The second processing chamber is used to generate a squeezing motion on the bubble water entering from the inlet of the variable diameter flow channel to reduce the size of the bubbles in the bubble water, and to output the bubble water to the washing chamber through the outlet of the variable diameter flow channel.

[0015] In the above embodiments, the bubbles in the sparkling water can be made smaller by squeezing motion.

[0016] In some embodiments, the second processing chamber is provided with a plurality of the variable diameter flow channels, and the second processing chamber is provided with a water inlet pipe protruding on the side where the inlet of the variable diameter flow channel is located, and the outlet of the water inlet pipe is connected to the inlet of all the variable diameter flow channels.

[0017] In the above embodiments, bubble water can flow from the large flow channel of the inlet pipe into multiple small variable-diameter flow channels, so that before entering the variable-diameter flow channels, larger bubbles in the inlet pipe can form smaller bubbles in the variable-diameter flow channels, making the water flow easier.

[0018] In some embodiments, the bubble generating module includes a third processing chamber and a bubble tube. The bubble tube has an air inlet and an air outlet, the size of which is smaller than that of the air inlet. The air inlet is used to introduce the gas. The third processing chamber has a second spiral flow channel. The air outlet is used to introduce gas bubbles into the second spiral flow channel. The third processing chamber is used to mix water entering from the inlet of the second spiral flow channel with the gas bubbles to form bubble water and to reduce the size of the gas bubbles. The bubble water is then output to the washing chamber through the outlet of the second spiral flow channel.

[0019] In the above embodiments, more bubbles can be introduced into the water and form small bubbles, thereby improving the cleaning ability of sparkling water to a certain extent.

[0020] In some embodiments, the bubble tube is disposed within the second spiral flow channel.

[0021] The above embodiments allow for a more compact design of the third processing cavity.

[0022] In some embodiments, the bubble tube is provided with a plurality of air outlets, which are located on the circumferential side of the bubble tube.

[0023] In the above embodiments, more small bubbles can be generated in the third processing chamber or the bubble generating chamber.

[0025] The aforementioned washing appliance can utilize the gas generated by the electrolysis of air by the air electrolysis module to mix with water to form bubble water.

[0035] Please refer to Figure 1 The present invention provides a washing appliance 100 including a washing chamber 10 and a bubble generating system 20.

[0036] The bubble generating system 20 includes an electrolytic air module 201 and a bubble generating module 203. The bubble generating module 203 includes an air inlet 2031, a water inlet 2032, and a water outlet 2033. The electrolytic air module 201 is connected to the air inlet 2031, and the washing chamber 10 is connected to the water outlet 2033. The water inlet 2032 is used to connect to a water source. The electrolytic air module 201 is used to electrolyze air to form gas that is introduced into the bubble generating module 203. The bubble generating module 203 is used to mix the gas with water to form bubbled water, and the bubbled water is introduced into the washing chamber 10 through the water outlet 2033.

[0037] The aforementioned bubble generating system 20 and washing appliance 100 utilize the gas generated by the electrolytic air module 201 after electrolyzing air to mix with water to form bubble water. This bubble water containing gas can be introduced into the washing chamber 10 to clean items. Since the bubble water containing gas has a certain cleaning ability, it can achieve consumable-free cleaning or reduce cleaning consumables even with light contaminants, thus reducing the long-term operating cost of the washing appliance 100.

[0038] Specifically, the washing appliance 100 includes, but is not limited to, dishwashers. The washing chamber 10 is used to place and clean items that need to be cleaned, such as tableware. Please refer to... Figure 1 The washing appliance 100 also includes a washing pump 40 and a spray assembly 50. The spray assembly 50 is located inside the washing chamber 10. The inlet of the washing pump 40 is connected to the washing chamber 10, and the outlet of the washing pump 40 is connected to the spray assembly 50. When the washing pump 40 is working, it can draw washing water from the washing chamber 10 and pump it to the spray assembly 50. The spray assembly 50 sprays the washing water into the washing chamber 10 to clean the items inside the washing chamber 10. The washing pump 40 allows the washing water to be recycled.

[0039] The bubble generating system 20 can produce bubbles. Specifically, the bubble generating system 20 includes an air electrolysis module 201 and a bubble generating module 203. The air electrolysis module 201 can be connected to an air source and is used to electrolyze air to form electrolyzed gas. The electrolyzed gas includes, but is not limited to, ozone and plasma gas. The electrolyzed gas is introduced into water to form bubbles, which can significantly improve the cleaning ability of bubble water containing gas. Optionally, all the electrolyzed gas can be introduced into the bubble generating module 203.

[0040] The electrolytic air module 201 is connected to the air inlet 2031, allowing the electrolyzed gas to be introduced into the bubble generating module 203. Optionally, the electrolytic air module 201 may include an electrolytic cell, which may consist of an electrolytic plate, electrodes, and an electrolytic cell body. The electrolytic cell is made of materials including, but not limited to, titanium alloy and stainless steel, ensuring the durability and corrosion resistance of the equipment, adapting to chemical corrosion during gas generation, and guaranteeing good electrolysis efficiency. Air is introduced into the electrolytic cell and, under the action of the electrodes, electrolyzes to form gas, which is then output to the bubble generating module 203.

[0041] The bubble generating module 203 includes an air inlet 2031, a water inlet 2032, and a water outlet 2033. The electrolytic air module 201 is connected to the air inlet 2031, so that the gas generated by the electrolytic air module 201 after electrolyzing air can be introduced into the bubble generating module 203.

[0042] The washing chamber 10 is connected to the water outlet 2033, allowing bubble water generated by the bubble generating module 203 to flow into the washing chamber 10. The water inlet 2032 is used to connect to a water source, allowing water to be obtained from the water source. Optionally, in Figure 1 In the illustrated embodiment, the washing appliance 100 further includes a water inlet valve 30, one end of which is connected to a water inlet 2032, and the other end is used to connect to a water source. The washing appliance 100 can control the flow of water through the water inlet valve 30.

[0043] The bubble generating module 203 can mix gas with water to form bubble water, and then introduce the bubble water into the washing chamber 10 through the water outlet 2033. Therefore, the washing appliance 100 can use bubble water containing gas to clean items, thereby enabling consumable cleaning even with light contaminants and reducing the long-term operating cost of the washing appliance 100.

[0044] It is understandable that when the electrolytic air module 201 is not working, the bubble generating system 20 can introduce air into the water, thereby changing the type of gas medium in the bubbles.

[0045] In some implementations, please refer to Figure 1The washing appliance 100 includes an air pump 202, and an electrolytic air module 201 is connected to an air inlet 2031 via the air pump 202. The air pump 202 is used to pump gas into the bubble generating module 203.

[0046] This increases the gas pressure input from the electrolytic air module 201 to the bubble generating module 203, allowing more bubbles to be introduced into the water, thereby improving the cleaning ability of the bubble water to some extent.

[0047] Optionally, in this embodiment, the gas generated by the electrolytic air module 201 can be output through the outlet of the electrolytic cell and connected to the inlet of the air pump 202 through a pipeline. The pipeline can be a flexible or rigid pipe, and the material of the pipeline includes, but is not limited to, silicone, polyethylene, and polyurethane, which can be corrosion-resistant and effectively sealed to prevent safety hazards caused by gas leakage. The outlet of the air pump 202 sends the gas into the bubble generating module 203 through the inlet end 2031 via the pipeline.

[0048] Optionally, the power of the air pump 202 is adjustable, thereby adjusting the gas pressure input to the bubble generating module 203 to meet the needs of different cleaning capabilities in various scenarios. In addition, due to the configuration of the air pump 202, the bubble generating system 20 has low requirements for inlet water pressure and flow rate when used in the washing appliance 100.

[0049] Furthermore, the concentration of gas bubbles can be adjusted by adjusting the operating power of the electrolytic air module 201 and / or the operating power of the air pump 202.

[0050] In some implementations, please refer to Figure 1 and Figure 2 The bubble generating module 203 includes a first bubble generating component 204, which includes a bubble generating chamber 2041 and a bubble tube 2042. The bubble generating chamber 2041 is provided with a water inlet 2032 for introducing water through the water inlet 2032. The bubble tube 2042 is provided with an air inlet 20421 and an air outlet 20422. The size of the air outlet 20422 is smaller than the size of the air inlet 20421. The air inlet 20421 is used to introduce gas, and the air outlet 20422 is used to introduce gas bubbles into the bubble generating chamber 2041, so that the gas bubbles and water mix in the bubble generating chamber 2041 to form bubble water.

[0051] Therefore, the structure of the bubble generating module 203 that produces gas-containing bubble water is simple.

[0052] Specifically, in this embodiment, the bubble generating chamber 2041 has sufficient space to ensure thorough mixing of gas and water, and its suitable shape promotes uniform bubble generation. The shape of the bubble generating chamber 2041 includes, but is not limited to, cylindrical and cuboid shapes. The bubble tube 2042 is provided with an inlet 20421 and an outlet 20422. The size of the outlet 20422 is smaller than that of the inlet 20421. The larger inlet 20421 facilitates rapid gas entry into the bubble tube 2042, while the smaller outlet 20422 helps generate smaller bubbles to mix with water and form sparkling water. Simultaneously, the larger inlet 20421 and the smaller outlet 20422 can create a pressure difference, making it easier for gas to be ejected from the outlet 20422 into the water, thereby enhancing the mixing efficiency of water and gas to a certain extent, generating finer bubbles, and improving the cleaning effect of the sparkling water. Figure 2 The circles in the text represent bubbles.

[0053] In some implementations, please refer to Figure 1 The bubble generating module 203 includes a second bubble generating component 205, and the first bubble generating component 204 is connected to the washing chamber 10 through the second bubble generating component 205. The second bubble generating component 205 is used to reduce the size of the bubbles in the bubble water.

[0054] Therefore, the second bubble generating component 205 can reduce the size of the bubbles in the sparkling water, thereby improving the cleaning ability of the sparkling water to a certain extent.

[0055] Specifically, the first bubble generating component 204 is connected to the washing chamber 10 via the second bubble generating component 205, allowing the bubbled water output from the first bubble generating component 204 to enter the second bubble generating component 205. The second bubble generating component 205 can reduce the size of the bubbles in the bubbled water output from the first bubble generating component 204. Smaller bubbles in the bubbled water output from the second bubble generating component 205 are less likely to escape from the water and are more stable, thus ensuring a certain level of bubble content and improving the cleaning ability of the bubbled water. Furthermore, smaller bubbles also allow for a more even distribution of bubbles in the water, thereby improving bubble uniformity.

[0056] In some implementations, please refer to Figure 3 The second bubble generating assembly 205 includes a first processing chamber 2051, which is provided with a first spiral flow channel 20511. The first processing chamber 2051 is used to cause the bubble water entering from the inlet of the first spiral flow channel 20511 to undergo spiral motion, thereby reducing the size of the bubbles in the bubble water, and then outputting the bubble water to the washing chamber 10 through the outlet of the first spiral flow channel 20511.

[0057] Therefore, the bubbles in sparkling water can be made smaller through spiral motion.

[0058] Specifically, the sparkling water enters the first spiral flow channel 20511 from the inlet of the first bubble generating component 204 and the first spiral flow channel 20511. The first spiral flow channel 20511 is a flow channel that can generate spiral motion of the sparkling water.

[0059] Optionally, in Figure 3 In the illustrated embodiment, the flow channel between the inlet and outlet of the first spiral flow channel 20511 is spiral-shaped. Because the bubble water has a certain flow velocity, after entering the spiral flow channel, it moves in a spiral motion along the spiral. The spiral water flow generates centrifugal force, pushing the bubbles outward from the center. Under the action of centrifugal force, larger bubbles are subjected to stronger external forces, causing them to move outward and break into smaller bubbles. Simultaneously, due to the difference in rotational speed at different positions of the bubble water, the water flow generates shear force, making it easier for the bubbles to be cut into smaller bubbles.

[0060] Optionally, in one embodiment, the flow channel between the inlet and outlet of the first spiral flow channel 20511 can be cylindrical in shape. The central axis of the inlet of the first spiral flow channel 20511 and the central axis of the flow channel between the inlet and outlet are set at an acute angle, so that the water flowing into the inlet of the first spiral flow channel 20511 has an oblique upward flow direction. When the water flow encounters the inner wall of the first processing chamber 2051, the oblique upward direction of the water flow is changed, so that the water flow makes a spiral motion around the central axis of the flow channel between the inlet and outlet. The central axis of the outlet of the first spiral flow channel 20511 can be parallel to the central axis of the inlet of the first spiral flow channel 20511.

[0061] In some implementations, please refer to Figure 4 The second bubble generating assembly 205 includes a second processing chamber 2052, which is provided with a variable diameter flow channel 20521. The second processing chamber 2052 is used to generate a squeezing motion on the bubble water entering from the inlet of the variable diameter flow channel 20521 using the variable diameter flow channel 20521, so that the bubbles in the bubble water become smaller, and the bubble water is output to the washing chamber 10 through the outlet of the variable diameter flow channel 20521.

[0062] Therefore, the bubbles in sparkling water can be made smaller by squeezing.

[0063] Specifically, the bubble-generating water enters the variable-diameter flow channel 20521 through the inlet of the first bubble generating component 204 and the variable-diameter flow channel 20521. The variable-diameter flow channel 20521 is a flow channel with a changing diameter, specifically, it can have a continuously changing diameter or a phased diameter change. The variable-diameter flow channel 20521 includes at least a large-diameter flow channel and a small-diameter flow channel arranged sequentially along the water flow direction A. When the bubble-generating water enters the small-diameter flow channel from the large-diameter flow channel, due to the decrease in diameter and the certain flow velocity of the bubble-generating water, the large bubbles are squeezed by the water flow and the inner wall of the second processing chamber 2052, thereby bursting and forming small bubbles.

[0064] Please combine Figure 4 In one embodiment, the variable-diameter flow channel 20521 includes a first flow channel 20522, a second flow channel 20523, and a third flow channel 20524 arranged sequentially along the water flow direction A. Along the water flow direction A, the first flow channel 20522 is a tapered cone, with its diameter continuously decreasing. When the bubble-filled water enters the first flow channel 20522, its flow velocity increases, causing a sudden decrease in pressure. The compression and stretching action causes large bubbles to burst, forming smaller bubbles.

[0065] Along the water flow direction A, the second flow channel 20523 is a constant diameter flow channel. Aerated water enters the second flow channel 20523 from the first flow channel 20522. Since the diameter of the second flow channel 20523 remains constant, the effect of the velocity increase caused by the first flow channel 20522 can be eliminated, ensuring that the aerated water can maintain a stable flow.

[0066] Along the water flow direction A, the third channel 20524 is a gradually expanding cone shape, and its diameter continuously increases. The continuously increasing diameter of the third channel 20524 gradually reduces the flow velocity of the bubble-filled water entering the third channel 20524 from the second channel 20523, thereby gradually releasing the pressure and preventing the bubbles from merging and breaking, making the bubbles more stable.

[0067] In some implementations, please refer to Figure 4 The second processing chamber 2052 is provided with multiple variable diameter flow channels 20521. A water inlet pipe 2053 is protruding on the side where the inlet of the variable diameter flow channel 20521 is located. The outlet of the water inlet pipe 2053 is connected to the inlet of all the variable diameter flow channels 20521.

[0068] Therefore, bubbled water can flow from the large flow channel of the inlet pipe 2053 into multiple small variable diameter flow channels 20521, so that larger bubbles in the inlet pipe 2053 can form smaller bubbles in the variable diameter flow channel 20521 before entering the variable diameter flow channel 20521, making the water flow easier.

[0069] Specifically, before entering the variable diameter flow channel 20521, the bubbly water may contain large air bubbles. These large air bubbles are not easy to squeeze into the variable diameter flow channel 20521, which may cause the water flow to be obstructed.

[0070] In this embodiment, the second processing chamber 2052 has a water inlet pipe 2053 protruding on the side where the inlet of the variable diameter flow channel 20521 is located. The water inlet pipe 2053 provides sufficient water to allow the bubble water generated by the first bubble generating component 204 to flow into the variable diameter flow channel 20521. The outlet of the water inlet pipe 2053 is connected to the inlet of all variable diameter flow channels 20521. Because the flow channel inside the water inlet pipe 2053 is relatively large, when the bubble water enters the smaller variable diameter flow channel 20521 from the larger water inlet pipe 2053, it will cause the flow velocity of the bubble water to continuously increase, thereby forming a pressure difference. The bubbles in the bubble water are squeezed, thereby turning large bubbles into small bubbles. The small bubbles are further squeezed in the variable diameter flow channel 20521 to form even smaller bubbles.

[0071] In this embodiment, the variable diameter flow channel 20521 includes a first flow channel 20522, a second flow channel 20523, and a third flow channel 20524 arranged sequentially along the water flow direction A. The structure of the variable diameter flow channel 20521 allows the bubbles in the bubble water to complete the final fluid redistribution and pressure buffering in a stable environment, achieving stable and uniform dispersion of fine bubbles in the bubble water.

[0072] In some implementations, please refer to Figure 5 The bubble generating module 203 includes a third processing chamber 2054 and a bubble tube 2042. The bubble tube 2042 has an air inlet 20421 and an air outlet 20422. The size of the air outlet 20422 is smaller than the size of the air inlet 20421. The air inlet 20421 is used to introduce gas. The third processing chamber 2054 has a second spiral flow channel 20541. The air outlet 20422 is used to introduce gas bubbles into the second spiral flow channel 20541.

[0073] The third processing chamber 2054 is used to mix water and gas bubbles entering from the inlet of the second spiral channel 20541 to form bubble water and to reduce the size of the gas bubbles, and to output the bubble water to the washing chamber 10 through the outlet of the second spiral channel 20541.

[0074] This allows more bubbles to be introduced into the water and form smaller bubbles, thereby improving the cleaning ability of sparkling water to some extent.

[0075] Specifically, in this embodiment, the third processing chamber 2054 has sufficient space to ensure thorough mixing of gas and water, while promoting the generation of bubble water through a suitable shape. The shape of the third processing chamber 2054 includes, but is not limited to, cylindrical, cuboid, etc.

[0076] The bubble tube 2042 has an air inlet 20421 and an air outlet 20422. The size of the air outlet 20422 is smaller than that of the air inlet 20421. The larger air inlet 20421 facilitates the rapid entry of gas into the bubble tube 2042, while the smaller air outlet 20422 helps generate smaller bubbles to mix with water and form sparkling water. Simultaneously, the larger air inlet 20421 and the smaller air outlet 20422 can create a pressure difference, making it easier for gas to be ejected from the air outlet 20422 into the water. This enhances the mixing efficiency of water and gas to a certain extent, generating finer bubbles and improving the cleaning effect of the sparkling water. Figure 5 The circles in the image represent bubbles, and the arrows indicate the direction of water flow.

[0077] The third processing chamber 2054 is provided with a second spiral flow channel 20541. The second spiral flow channel 20541 is a flow channel that can generate spiral motion in the bubble water.

[0078] Optionally, in Figure 5 In the illustrated embodiment, the flow channel between the inlet and outlet of the second spiral flow channel 20541 can be cylindrical in shape. The central axis of the inlet of the second spiral flow channel 20541 and the central axis of the flow channel between the inlet and outlet are set at an acute angle, so that the water flowing into the inlet of the second spiral flow channel 20541 has an oblique upward flow direction. When the water flow encounters the inner wall of the third treatment chamber 2054, the oblique upward direction of the water flow is changed, so that the water flow moves in a spiral motion around the central axis of the flow channel between the inlet and outlet. The central axis of the outlet of the second spiral flow channel 20541 and the central axis of the inlet of the second spiral flow channel 20541 can be parallel to each other.

[0079] Alternatively, in one embodiment, the structure of the second spiral flow channel 20541 can be the same as... Figure 3 The structure of the first spiral channel 20511 shown is the same.

[0080] Because the water flow has a certain velocity, it enters the second spiral channel 20541 and moves in a spiral motion along it. The spiral water flow generates centrifugal force and shear force, which causes the large bubbles released from the air outlet 20422 to be broken into smaller bubbles by the disturbance of the spiral, thereby increasing the specific surface area of ​​the bubbles per unit volume and further improving the gas dissolution rate and mixing efficiency. The spiral of the bubble water generates centrifugal force and shear force, which pushes the bubbles to collide and break apart, gradually forming smaller and more stable bubbles.

[0081] In some implementations, please refer to Figure 5 The bubble tube 2042 is located inside the second spiral flow channel 20541.

[0082] This allows for a more compact design of the third processing chamber 2054.

[0083] Specifically, by placing the bubble tube 2042 inside the second spiral flow channel 20541, the gas generating chamber and the processing chamber are integrated into one unit. The bubble tube 2042 releases gas inside the second spiral flow channel 20541. The gas release point and the mixing area highly overlap, so that the entire process of gas generation and dispersion is carried out in a controlled flow channel environment, which improves the gas-liquid mixing efficiency and reduces bubble loss caused by bubble-water flow.

[0084] In some implementations, please refer to Figure 5 The bubble tube 2042 is provided with multiple air outlets 20422, which are located on the circumferential side of the bubble tube 2042.

[0085] This allows for the generation of more small bubbles within the third processing chamber 2054 or the bubble generating chamber 2041.

[0086] Specifically, the bubble tube 2042 is provided with multiple air outlets 20422, and the arrangement of the air outlets 20422 includes, but is not limited to, a uniform arrangement at equal intervals. Multiple air outlets 20422 can realize the simultaneous release of gas along the circumference of the bubble tube 2042, making the gas dispersion direction more uniform, and significantly expanding the contact range between the gas and the water in the third processing chamber 2054 or the bubble generating chamber 2041, thereby generating more small bubbles.
