Description

Technical Field

[0001] The invention belongs to the field of washing equipment, and in particular relates to a water tank type washing equipment. Background Art

[0002] As living standards improve, people's demands for a higher quality of life are becoming increasingly stringent, leading to higher expectations for kitchenware, aiming to simplify tedious household chores. The cleanliness of kitchenware has always been a major concern for people. The mess left after a meal, with greasy hands, is often unbearable. Detergents are commonly used to wash vegetables, fruits, and dishes. This method leaves some detergent residue on surfaces, adversely affecting human health. Furthermore, water containing detergent enters sewers, causing pollution. Dishwashers, as an excellent product, have gradually become part of people's lives. Dishwashers automatically wash dishes such as bowls, chopsticks, plates, dishes, knives, forks, and even fruits and vegetables, greatly facilitating daily life. Existing dishwashers often use mechanical cleaning mechanisms and the impact of mechanically generated water jets. These methods suffer from low cleaning rates, fragile dishes, limited functionality, poor practicality, and limited widespread adoption. Furthermore, conventional dishwashers often use high-temperature washing methods, using high temperatures to sterilize and disinfect. Ozone is a strong oxidant. The advent of sink-type dishwashing machines has solved the problem of easily washing large quantities of greasy dishes without touching hands, achieving the goal of automatic dishwashing and bringing significant convenience to people's lives. Sink-type dishwashing machines integrate a common sink with a dishwasher, offering functions such as heating to remove grease, running water to remove food residue, and disinfecting to remove pesticide residue. They are suitable for washing dishes, fruits, and vegetables. Existing sink-type dishwashers generally use ultrasonic cleaning, but these methods often provide suboptimal disinfection and sterilization. Ozone is well known for its deodorizing, disinfecting, and oxidizing properties for organic matter. As a strong oxidant, ozone decolorizes many organic colorants and kills bacteria. It is used as a disinfectant in wineries and cold storage rooms, and for drinking water purification. Ozone destroys flavorings, odorants, colorants, and bacteria and viruses in impure water through oxidation. Currently, few devices on the market use ozone to disinfect and sterilize vegetables, fruits, and dishes.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a sink-type washing device that has both ozone water cleaning and ozone gas disinfection functions. The device can significantly improve the solubility of ozone in washing water, increase the ozone content in the ozone washing water, and thus significantly enhance the sterilization ability of the ozone washing water. The ozone gas can also be discharged into the washing tank to disinfect tableware. The sink-type washing device can be a sink-type dishwasher.

[0005] To address the above technical issues, the present invention adopts a technical solution based on the following basic concept: a water tank washing device comprising a washing tank and an ozone device. The washing tank comprises an inner tank and an outer tank stacked together, with a first chamber with a certain accommodation space formed between the inner and outer tanks; the outer tank is recessed downward to form a second chamber; the ozone device comprises an ozone generator, an air outlet device disposed on the outer tank with its top end facing the first chamber, and an air guide pipe connecting the air outlet device and the ozone generator. The first chamber is used to pre-dissolve and hold ozone washing water.

[0006] This design solves the problem that conventional dishwashers, which can only reach a maximum temperature of approximately 65-80°C, are ineffective in killing certain heat-resistant bacteria. Some users may use plastic tableware, which can denature and even produce toxins during high-temperature washing, posing a health hazard. This invention utilizes an ozone generator to generate ozone, which dissolves in water and is then used to wash the tableware. This chemical reaction kills bacteria quickly without damaging the tableware. It also removes pesticide residues and odors from fruits and vegetables, achieving a truly "green" sterilization and disinfection process. Furthermore, the gaseous ozone that remains undissolved in the water is introduced into the washing tank for further disinfection, achieving dual cleaning and disinfection. Addressing the two technical issues of dissolving ozone in water and ensuring its entry into the washing tank simultaneously makes the placement of the ozone device and the structural layout of the washing equipment particularly important. This technical solution fully resolves these issues.

[0007] The present invention is further configured as follows: the air outlet device is arranged at the bottom of the first cavity and embedded in the outer groove.

[0008] This design optimizes the placement of the gas outlet. Ozone has a lower density than wash water, so placing the gas outlet at the bottom of the outer tank significantly increases the dissolution rate of ozone bubbles in the wash water, increasing their contact with water and thus improving ozone's solubility. Furthermore, any undissolved ozone can be better directed into the wash tank for disinfection and sterilization.

[0009] The air outlet device is embedded into the mounting groove with a through hole formed by the outward recess of the outer tank, and the lower connecting part is connected with the air guide pipe through the through hole.

[0010] Preferably, the number of air outlet devices is multiple.

[0011] Through the above design, the connection between the air outlet device and the outer tank is solved, the mounting groove can better provide positioning for the air outlet device, and the connection between the air outlet device and the outer tank is maintained.

[0012] The air outlet device is further provided with a connecting piece for positioning and connecting with the outer tank.

[0013] Preferably, corresponding threads are arranged on the lower connecting part and the connecting piece, and the connecting piece is screwed with the lower connecting part on the outer side of the outer tank.

[0014] Further preferably, coaxial bolt holes are arranged at corresponding positions of the lower connecting part and the connecting piece, and the two are connected by screws penetrating through the bolt holes.

[0015] Still further preferably, the connecting piece is a flip buckle arranged on the lower side of the outer tank, and the lower connecting part is provided with a clamping protrusion corresponding to the flip buckle, so that the lower connecting part can be clamped into the connecting piece to realize positioning.

[0016] Still further preferably, the air guide pipe is provided with a one-way valve, and the one-way valve only allows gas to pass through.

[0017] Still further preferably, the number of one-way valves is multiple.

[0018] Through the above design, the reasonable connection between the air outlet device and the outer tank is realized, the connecting piece can effectively connect the device and the washing tank together, and the positioning of the two is avoided, so that the relative movement of the two is avoided. The connection is a detachable connection, which can flexibly realize the disassembly operation when the equipment needs to be assembled, disassembled and the like. Moreover, the design of the one-way valve can prevent the washing water from flowing back into the ozone generator, and the arrangement of the one-way valve greatly expands the structural applicability of the air guide pipe. In this case, the air guide pipe can be any structure of the existing technology. In the present application, the lower connecting part and the connecting piece can also be connected by other implementable screwing, clamping and the like. The connection mode and structure can be multiple.

[0019] The air outlet device is further provided with a plurality of gas holes for gas to pass through.

[0020] Preferably, the plurality of gas holes are arranged periodically.

[0021] This design significantly reduces the volume of ozone bubbles that overflow the outlet, thereby increasing the surface area of ​​contact between the ozone bubbles and the wash water, and thus increasing ozone solubility in the wash water. The periodic distribution ensures that the ozone bubbles are spaced as evenly as possible, preventing them from interfering with each other as they move through the wash water, thus preventing excessive concentration of ozone bubbles that could affect their solubility. For any undissolved ozone, this technical solution ensures that it remains well dispersed upon entering the wash tank, facilitating its disinfecting properties.

[0022] The present invention is further configured as follows: a sealing device is provided between the gas outlet device and the outer groove to achieve sealing between the two;

[0023] Preferably, the sealing device is a sealing gasket.

[0024] The above design achieves a sealed connection between the air outlet and the outer tank. Because both the air outlet and the outer tank can be made of rigid materials, the contact between them is rigid, and a small gap is likely to exist at the joint. The provision of a sealing device completely resolves this problem. The sealing device can be made of an elastic material, such as rubber, silicone, or the like. When the air outlet device and the outer tank are assembled, the pressure fit between the two causes the sealing device to undergo a certain degree of elastic deformation, thereby achieving a seal between the two.

[0025] The present invention is further configured as follows: the air outlet device includes a seat portion and a top portion that are matched and connected, the seat portion is a centrally connected tubular structure, the lower end of the seat portion is a lower connecting portion, the upper end of the seat portion is an upper connecting portion, and the top portion is embedded in the upper connecting portion to achieve connection;

[0026] Preferably, the seat is made of an injection moldable material, the top is made of a ceramic material, and the seat is connected to the top by integral injection molding.

[0027] Preferably, the gas outlet device is made of a functional ceramic material with ozone activation performance.

[0028] This design achieves a more rational air outlet structure, facilitating installation while ensuring effective ozone delivery. Furthermore, the connection between the top and base is achieved by integrally injection-molding a moldable material, such as plastic, onto the ceramic top. This simpler connection method also ensures a seamless connection between the top and base. The functional ceramic material activates ozone molecules into ions, facilitating disinfection.

[0029] The present invention is further configured such that an air storage cavity having a certain accommodating space is formed between the top portion and the seat portion.

[0030] With this design, ozone gas from the air duct is passed through the outlet device and then into the gas storage chamber. Because the gas storage chamber has a certain amount of space, ozone accumulates and is compressed to a certain degree there, forming ozone gas with a certain pressure. This, in turn, gives the ozone greater pressure and travel speed when it is ejected from the air hole, which helps it dissolve in the wash water. The provision of the gas storage chamber also increases the contact probability between the ozone gas and the functional ceramic, promoting ozone ionization and thus increasing its solubility.

[0031] The present invention is further configured as follows: the inner tank is connected to the outer tank, so that the first cavity is connected to the washing cavity in the inner tank, and a filtering device is provided between the first cavity and the washing cavity.

[0032] Through the above design, the ozone washing water in the first cavity can flow more smoothly into the washing cavity, realizing the soaking and cleaning of tableware, fruits and vegetables with the ozone washing water; and, when the washing device in this technical solution is used in conjunction with the spraying device, the tableware, fruits and vegetables can be cleaned by soaking and spraying the ozone washing water in a mixed manner. On the other hand, the ozone generated by the ozone device cannot be completely dissolved in the washing water, so that a part of the ozone exists in the form of gas. The gaseous ozone will move upward in the washing device, so that the tableware, fruits and vegetables are immersed in the ozone atmosphere. The tableware, fruits and vegetables are sterilized and disinfected by the gaseous ozone, which increases the ozone utilization rate of the washing device while also realizing the coordination between multiple ozone disinfection methods and improving the disinfection efficiency.

[0033] The present invention is further configured such that: the sink-type washing device is a dishwasher.

[0034] The present invention is further configured such that the pore density at the top of the air outlet device is greater than 10PPI.

[0035] Through the above design, the volume of ozone bubbles overflowing the gas outlet device can be significantly reduced, thereby increasing the specific surface area of ​​the ozone bubbles in contact with the washing water, thereby increasing the solubility of ozone in the washing water.

[0036] The present invention is further configured as follows: the water tank type washing equipment includes a spray device connected to the first cavity, and the spray device draws ozone washing water solution from the first cavity / second cavity and sprays it into the inner tank for cleaning operation.

[0037] Through the above design, the separation of ozone washing water and washing water can be achieved. When the equipment is in use, the ozone washing water spraying operation is only performed when disinfection is required, so as to avoid the waste of the cleaning ability of the ozone washing water by the excessive food residue left on the tableware in the early stage of washing, which can be removed by conventional washing.

[0038] The present invention is further configured such that the top end of the air outlet device has the same curvature as the inner surface of the outer groove, so that the two form a smooth transition surface after installation.

[0039] Through the above design, the air outlet device does not protrude from the inner surface of the outer tank. When the ozone washing water is pre-dissolved in the first chamber, the fluidity of the ozone washing water will not be affected by the uneven structure in the first chamber, thereby avoiding affecting the solubility of ozone in the ozone washing water.

[0040] The present invention is further configured as follows: there are multiple air outlet devices, and the multiple air outlet devices are distributed at the bottom of the outer tank.

[0041] Through the above design, the solubility of ozone in ozone washing water can be further improved.

[0042] The present invention is further configured as follows: a plurality of protrusions / grooves for connection are provided at circumferential positions on the outer side of the air outlet device, and a plurality of grooves / protrusions corresponding to the protrusions / grooves are provided at the position where the outer groove connects to the air outlet device, so that the protrusions / grooves can be slidably embedded in the grooves / protrusions;

[0043] Preferably, the number of the corresponding grooves and protrusions is three, and the grooves and protrusions are evenly distributed along the connection between the air outlet device and the outer groove;

[0044] Further preferably, the corresponding grooves and protrusions are both strip-shaped structures extending in the vertical direction;

[0045] Still further preferably, the cross-sections of the protrusions and the grooves are major arc surfaces of the same size;

[0046] More preferably, the hinging edge of the major arc surface is intersecting with the outer circumferential position of the air outlet device.

[0047] Through the above design, a reasonable connection between the air outlet device and the outer groove is achieved. The design of multiple protrusions / grooves can not only firmly connect the air outlet device and the outer groove, but also prevent relative rotation between the two, thereby avoiding the formation of gaps at the connection position. In addition, while achieving a stable connection between the air outlet device and the outer groove, the number of connecting parts is controlled as much as possible to avoid the connection structure being too complex and not conducive to processing and production. It can also increase the contact area between the grooves and protrusions at the connection, making the connection between the two more secure; and increasing the contact area between the connecting parts can avoid stress concentration caused by interaction between the two, which may cause performance risks.

[0048] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0049] 1. The technical solution of the present invention can completely solve the problem that ordinary high-temperature disinfection methods have a negative impact on tableware and washing equipment. The present invention uses ozone to disinfect tableware, fruits and vegetables, and kills bacteria by chemical reaction. The sterilization speed is fast and will not cause any damage to the tableware. At the same time, it can also remove pesticide residues on fruits and vegetables and eliminate odors, truly realizing a "green" sterilization process.

[0050] 2. The technical solution of the present invention more reasonably arranges the position of the gas outlet device. Ozone has a lower density than washing water. Placing the gas outlet device at the bottom of the outer tank can significantly increase the dissolution process of ozone bubbles in washing water, increase the contact probability of ozone bubbles with water, and thus improve the solubility of ozone; and can discharge ozone gas into the washing tank to disinfect tableware. The sink-type washing device can be a sink-type dishwasher;

[0051] 3. The technical solution of the present invention enables the ozone washing water in the first chamber to flow more smoothly into the washing chamber, realizing the soaking and cleaning of tableware, fruits and vegetables with the ozone washing water; and, when the washing device in this technical solution is used in conjunction with the spraying device, the tableware, fruits and vegetables can be cleaned by soaking and spraying the ozone washing water in a mixed manner. On the other hand, the ozone generated by the ozone device cannot be completely dissolved in the washing water, so that a part of the ozone exists in the form of gas. The gaseous ozone will move upward in the washing device, so that the tableware, fruits and vegetables are immersed in the ozone atmosphere. The tableware, fruits and vegetables are sterilized and disinfected by the gaseous ozone, which increases the ozone utilization rate of the washing device while also realizing the coordination between multiple ozone disinfection methods and improving the disinfection efficiency.

DETAILED DESCRIPTION

[0060] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0061] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0062] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0063] Example 1

[0064] like Figure 1-Figure 3As shown, the water tank type washing equipment in the embodiment comprises a washing tank, an ozone device, the washing tank comprises an inner tank and an outer tank 3 arranged in a stack, a first cavity 1 with a certain accommodating space is formed between the inner tank and the outer tank 3; the outer tank 3 is concave downward to form a second cavity 2; the ozone device comprises an ozone generator 4, an air outlet device 5 arranged on the outer tank 3 and having a top end towards the first cavity 1, and a gas guide pipe 6 for connecting the air outlet device 5 and the ozone generator 4. The technical scheme solves the problem that the highest temperature that can be reached in a common dishwasher is about 65-80℃, and some bacteria resistant to high temperature cannot be effectively killed. Some users may use plastic tableware, which may be denatured during high-temperature cooking and washing, and even produce toxins, endangering the health of consumers. The ozone generator is used to generate ozone, which is dissolved in water, and the ozone washing water is used to wash tableware, the chemical reaction is used to kill bacteria, the bacteria killing speed is fast, the tableware is not damaged, and the pesticide residues on fruits and vegetables are removed, the odor is removed, and a "green" sterilization and disinfection process is truly realized. And the gaseous ozone not dissolved in water is introduced into the washing tank for further disinfection of the tableware, realizing double cleaning and double disinfection. To solve the two technical problems of dissolving ozone in water and introducing ozone into the washing tank, the setting position of the ozone device and the structure layout of the washing equipment are particularly important. The technical scheme completely solves the above problems.

[0065] The air outlet device 5 in the embodiment is arranged at the bottom of the first cavity 1 and embedded in the outer tank 3. The lower end of the air outlet device 5 is a lower connecting part 9 with a through hole, the air outlet device 5 is embedded in the mounting groove with a through hole formed by the outward recess of the outer tank 3, and the lower connecting part 9 is connected with the gas guide pipe 6 through the through hole; the number of the air outlet device 5 is multiple, and is distributed at different positions of the low side of the outer tank 3. Through the above design, the position of the air outlet device is more reasonably set. The density of ozone is lower than that of washing water, and the air outlet device is arranged at the bottom of the outer tank, which can obviously increase the dissolution distance of ozone bubbles in the washing water, increase the contact probability of ozone bubbles and water, and further improve the dissolution capacity of ozone. And the undissolved ozone gas can be better introduced into the washing tank for disinfection and sterilization.

[0066] Furthermore, the air outlet device 5 is positioned and connected to the outer tank 3 via a connector 10. The lower connecting portion 9 and the connector 10 are provided with corresponding threads. The connector 10 is screwed onto the lower connecting portion 9 on the outside of the outer tank 3. A one-way valve is provided on the air duct 6, which only allows gas to pass through. There are multiple one-way valves. This design solves the connection problem between the air outlet device and the outer tank. The installation groove effectively positions the air outlet device and maintains the connection between the air outlet device and the outer tank. Furthermore, the installation groove further simplifies the installation of the air outlet device. The connector effectively connects the device to the washing tank and positions them, preventing relative movement. This connection is detachable, allowing for flexible assembly and disassembly when the equipment needs to be assembled or disassembled. Furthermore, the one-way valve prevents wash water from backflowing into the ozone generator. The provision of the one-way valve significantly expands the structural applicability of the air duct, allowing it to be of any existing tubular structure.

[0067] In this embodiment, the air outlet device is positioned lower relative to the first chamber and higher relative to the second chamber. This allows small impurities removed from the sink-type washing machine during use to sink into the second chamber without affecting the air outlet device. After all, the air outlet device is provided with air holes. If the air holes become clogged (for example, liquid grease will condense into lumps over time), the air outlet device will not be able to fully function. The coordination between the chambers, as well as the position and structural design of the air outlet device, completely solve this problem. Furthermore, the technical solution in this embodiment connects the ozone generator to the sink via the structure of the mounting bracket 8. The installation of the mounting bracket 8 eliminates the need for the ozone generator to be attached to the sink, providing more space for the installation of other components and structural adjustments. Furthermore, the mounting bracket in this embodiment has a multi-stage structure, allowing multiple ozone generators to be installed simultaneously to work together, thereby improving ozone generation efficiency. Alternatively, the mounting bracket can provide support for the wiring of the sink-type washing machine.

[0068] Example 2

[0069] like Figure 4As shown, the water tank type washing equipment described in the embodiment is different from the above-mentioned embodiment in that the top end of the air outlet device is provided with a plurality of air holes for air to pass through; the plurality of air holes are periodically arranged. The air outlet device and the outer tank are provided with a sealing device 11 to realize sealing between the two; the sealing device 11 is a sealing gasket. The technical scheme in the embodiment realizes reasonable connection between the air outlet device and the outer tank. The sealing gasket is flexible and diverse in selection, which can be a block structure with a large elastic modulus and a through hole in the middle. When assembling, the sealing gasket is filled into the mounting groove, and then the air outlet device is installed. The air outlet device is pressed downward, so that the elastic gasket is deformed, and then fills the connection between the mounting groove and the air outlet device (including the four around the air outlet device), so that the sealing device can play a sealing role from multiple directions.

[0070] Further, the air outlet device in the embodiment includes a seat part 13 and a top part 12 connected together, the seat part 13 is a middle through tubular structure, the lower end of the seat part 13 is a lower connecting part 9, the upper end of the seat part 13 is an upper connecting part 15, and the top part 12 is embedded in the upper connecting part 15 to realize connection; preferably, the seat part 13 is made of a material that can be injection molded, the top part 12 is made of a ceramic material, and the seat part 13 is connected with the top part 12 by integral injection molding. Integral injection molding means that the top part 12 after molding is embedded in a mold for molding the seat part 13, and then the mold is closed, extruded, pressure maintained, and opened, so that the flowing injection molding material wraps the top part 12 in the appropriate position and forms a whole. Through the above structure design of the air outlet device, the air outlet device is easier to install, and the connection between the top part and the seat part is realized by injection molding the injection molding material such as plastic onto the ceramic top part, which is a simpler connection method and can also ensure that there is no gap between the top part and the seat part. Further, the top part 12 and the seat part 13 form a gas storage cavity 14 with a certain accommodation space. The gas storage cavity 14 can guide the ozone gas from the gas guide pipe into the air outlet device and then into the gas storage cavity. Since the gas storage cavity 14 has a certain accommodation space, the ozone is gathered and compressed to a certain extent in the cavity, forming ozone gas with a certain pressure, so that the ozone has greater pressure and travel speed when sprayed out of the air hole, which helps the ozone to dissolve in the washing water. And the setting of the gas storage cavity can increase the contact probability between the ozone gas and the functional ceramic, which is beneficial to the ionization of ozone, thereby increasing the dissolution capacity of ozone.

[0071] Embodiment three

[0072] The sink type washing equipment described in the embodiment is different from the above-mentioned embodiments in that the inner tank is communicated with the outer tank, the first cavity is communicated with the washing cavity in the inner tank, and the filter device is arranged between the first cavity and the washing cavity. Through the above design, the ozone washing water in the first cavity can flow into the washing cavity more smoothly, so as to realize the soaking cleaning of tableware and fruits and vegetables by the ozone washing water. When the washing device in the technical solution is used in cooperation with the spraying device, the tableware and fruits and vegetables can be cleaned by the mixed cleaning of soaking and spraying in multiple modes by the ozone washing water. On the other hand, the ozone generated by the ozone device cannot be completely dissolved in the washing water, so that a part of the ozone exists in the form of gas. The gaseous ozone moves upward in the washing equipment, so that the tableware and fruits and vegetables are immersed in the ozone atmosphere, the tableware and fruits and vegetables are sterilized and disinfected by the gaseous ozone, the ozone utilization rate of the washing equipment is increased, and the cooperation between multiple ozone disinfection modes is realized, so that the disinfection efficiency is improved.

[0073] Further, coaxial bolt holes are arranged at positions corresponding to the lower connecting part and the connecting piece in the embodiment, the positions corresponding to the bolt holes of the lower connecting part and the connecting piece are matched during installation, the bolts are screwed into the bolt holes formed by the two to realize connection; preferably, the bolt holes are at least two symmetrically arranged. The connection mode makes the contact surface of the connecting piece and the lower connecting part be subjected to multi-point force, and the plurality of bolts connect the two together at different positions to ensure the uniformity of the force between the two, further strengthening the stability of the assembly relationship after installation. Even if vibration occurs in the use of the matching function, it will not be loose.

[0074] Embodiment four

[0075] The sink type washing equipment described in the embodiment is different from the above-mentioned embodiments in that the connecting piece is a flip buckle arranged at the lower side of the outer tank (or the lower side of the installation groove), and the lower connecting part is provided with a clamping convex corresponding to the flip buckle, so that the lower connecting part can be clamped into the connecting piece to realize positioning between the two; preferably, the flip buckle and the clamping convex are a plurality of cooperatively arranged, and the plurality of flip buckles and clamping convexes are symmetrically arranged. On the one hand, the design greatly reduces the installation difficulty of the air outlet device, and facilitates user operation. On the other hand, the buckle structure has more structural stability than the threaded connection. Even if the possibility of loosening occurs, the clamping convex will continue to maintain the fit of the two under the locking force of the flip buckle.

[0076] The sink type washing equipment in each of the above embodiments can be a sink type dish washing machine.

[0077] The technical solution of the present invention can completely solve the problem that ordinary high-temperature disinfection methods have a negative impact on tableware and washing devices; the present invention uses ozone to disinfect tableware, fruits and vegetables, and uses chemical reactions to kill bacteria. The sterilization speed is fast and will not cause any damage to the tableware. At the same time, it can also remove pesticide residues on fruits and vegetables and eliminate odors, truly realizing a "green" sterilization process; the position of the gas outlet device is more reasonably set. The position of the gas outlet device is more reasonably set. Ozone has a lower density than washing water. Placing the gas outlet device at the bottom of the outer tank can significantly increase the dissolution process of ozone bubbles in washing water, increase the contact probability of ozone bubbles with water, and thus improve the solubility of ozone. In addition, the ozone gas that has not dissolved can be better passed into the washing tank for disinfection and sterilization.

[0078] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
