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] With the improvement of living standards, people have higher and higher requirements for the quality of life, and thus higher and higher requirements for kitchen utensils, in order to simplify the tedious housework. The cleanliness of kitchen utensils has always been one of the issues that people are very concerned about. Usually, when faced with the mess after a meal, it is unbearable to have hands full of oil. In the prior art, people mainly use detergents to wash vegetables, fruits and dishes. In this way of washing, some detergents will remain on the surface of the objects, which will have an adverse effect on human health. At the same time, water containing detergents will enter the sewer, causing pollution. As an excellent product, dishwashers have gradually entered people's lives. Dishwashers are equipment that automatically washes bowls, chopsticks, plates, dishes, knives, forks and other tableware and even fruits and vegetables, which greatly facilitates people's lives. Existing dishwashers mostly use machinery and the impact force of water flow generated by the machinery for cleaning. They have the disadvantages of low cleaning rate, fragile tableware, single function, poor practicality, and difficulty in popularization. In addition, ordinary dishwashers on the market often use high-temperature boiling and washing to achieve the effect of sterilization and disinfection. Ozone is a strong oxidant. The emergence of sink-type washing machines solves the problem that a large number of oily tableware can be easily washed without touching hands, achieving the purpose of automatic dishwashing, and bringing great convenience to people's lives. The sink-type washing machine is an integrated design of a common sink and a dishwasher. It has the functions of heating to remove grease, water flow to remove food residues, and disinfection to remove pesticide residues. It is suitable for washing tableware, fruits and vegetables and other items. Existing sink-type dishwashers generally use ultrasonic cleaning methods, but the existing sink-type dishwashers usually have unsatisfactory sterilization and disinfection effects. As we all know, ozone has the characteristics of deodorization, disinfection, and oxidation of organic matter. Ozone, as a strong oxidant, decolorizes many organic colorants and kills bacteria. It is used as a disinfectant in wineries and cold storage rooms and for purifying drinking water. Ozone destroys condiments, odor substances and colorants, as well as bacteria and viruses in impure water through oxidation. At present, there are few devices on the market that 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 prior art and provide a water tank type washing equipment, including a washing tank and an ozone device, wherein the ozone device and the washing tank have a more reasonable connection and installation method, which can fully exert the disinfection effect of the generated ozone washing water on the one hand, and avoid water leakage between the ozone device and the washing tank on the other hand.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a water tank type washing equipment, comprising: a washing tank, an ozone device; the ozone device comprises an ozone generator, an air outlet device arranged on the washing tank, and an air duct for connecting the air outlet device and the ozone generator; the lower end of the air outlet device is a lower connecting part which is through, and the air outlet device is embedded in an installation groove with a through hole formed by the washing tank being recessed to the outside, and the lower connecting part passes through the through hole to be connected with the air duct.

[0006] The above design solves the problem that the highest temperature that can be reached in ordinary dishwashers is about 65-80°C, which cannot effectively kill some high-temperature resistant bacteria. Some users may use plastic tableware, which may denature or even produce toxins during high-temperature boiling and washing, endangering the health of consumers. The present invention uses an ozone generator to generate ozone, which is dissolved in water and then washed with ozone washing water to wash tableware. Chemical reactions are used to kill bacteria, with a fast sterilization speed, without causing any damage to tableware. At the same time, it can also remove pesticide residues on fruits and vegetables and remove odors, truly realizing a "green" sterilization and disinfection process.

[0007] The present invention is further configured as follows: the gas outlet device is arranged at the bottom of the washing tank and embedded therein;

[0008] Further preferably, a one-way valve is provided on the air guide tube, and the one-way valve only allows gas to pass through;

[0009] Still more preferably, there are multiple one-way valves.

[0010] Through the above design, the position of the gas outlet device is set more reasonably. Ozone has a lower density than washing water. Setting the gas outlet device at the bottom of the outer tank can significantly increase the dissolution distance of ozone bubbles in washing water, increase the contact probability of ozone bubbles and washing water, and thus improve the solubility of ozone. Through the above design, it is possible to further prevent washing water from flowing back into the ozone generator. The setting of the one-way valve greatly expands the structural applicability of the air guide pipe. In this case, the air guide pipe can be a pipe structure of any structure in the prior art.

[0011] The present invention is further configured as follows: the air outlet device is positioned and connected to the installation groove through a connecting piece, corresponding threads are provided on the lower connecting part and the connecting piece, and the connecting piece is screwed to the lower connecting part on the outer side of the installation groove.

[0012] Through the above design, a reasonable connection between the air outlet device and the washing tank is achieved, and the setting of the connecting piece can effectively connect the air outlet device and the washing tank together, and position the two to prevent the two from moving relative to each other. The connection is a detachable connection, and when the equipment needs to be assembled, disassembled, etc., the connection structure can flexibly realize the disassembly operation.

[0013] The present invention is further configured as follows: a sealing device is provided between the air outlet device and the mounting groove to achieve sealing between the two;

[0014] Preferably, the sealing device is a sealing gasket.

[0015] Through the above design, a sealed connection between the air outlet device and the washing tank can be achieved. Since both the air outlet device and the mounting groove can be made of rigid materials, the contact between the two is rigid contact, and there is likely to be a small gap at the matching point. The provision of the sealing device completely solves the above problem. The sealing device can be made of elastic material, such as rubber, silicone, etc. When the air outlet device and the washing tank are assembled, the sealing device undergoes a certain degree of elastic deformation through the pressure matching between the two, thereby achieving a seal between the two.

[0016] The present invention is further configured as follows: the outer groove is recessed downward to form a second cavity; the gas outlet device is arranged at the bottom of the pre-dissolution cavity, so that the position of the gas outlet device is relatively lower than the pre-dissolution cavity and relatively upper than the second cavity.

[0017] Through the above design, the fine dirt washed off by the sink-type washing machine during use sinks into the second cavity and does not affect the air outlet device. After all, the air outlet device is provided with air holes. If the air holes are blocked (such as liquid grease, which will condense into blocks over time), the air outlet device will not be able to fully exert its functionality. The matching relationship between the cavities, and the position and structural design of the air outlet device completely solve this problem.

[0018] The present invention is further configured as follows: the air outlet device includes a seat and a top that are matched and connected, the seat is a centrally-through tubular structure, the lower end of the seat is a lower connecting part, the upper end of the seat is an upper connecting part, the top is embedded in the upper connecting part to achieve connection, and a plurality of air holes for gas ejection are provided on the top.

[0019] Preferably, the connection between the top and the upper connecting portion is a threaded connection;

[0020] Alternatively, a step is provided on the inner side of the upper connecting portion so that the bottom end of the top portion can overlap the step, and a stopper is used at the outer top of the air outlet device to limit the position of the air outlet device with the upper connecting portion.

[0021] Through the above design, a more reasonable gas outlet device structure is obtained, which is easy to install and can also achieve a good ozone spraying effect.

[0022] The present invention is further configured as follows: an air storage cavity having a certain accommodation space is formed between the top portion and the seat portion;

[0023] Preferably, the gas outlet device is made of a functional ceramic material having ozone activation performance.

[0024] Through the above design, the ozone gas from the air guide pipe is introduced into the air outlet device and then into the air storage chamber. Since the air storage chamber has a certain accommodation space, the ozone is gathered there and compressed to a certain extent to form ozone gas with a certain pressure, so that the ozone has a greater pressure and travel speed when it is ejected from the air hole, which is conducive to the dissolution of ozone in the washing water. In addition, the setting of the air storage chamber can increase the contact probability between the ozone gas and the functional ceramics, which is conducive to the ionization of ozone, thereby increasing the solubility of ozone.

[0025] The present invention is further configured such that: the lower connecting portion extends a certain distance into the air storage cavity to form an annular step.

[0026] The above design can increase the ability of the air outlet device to prevent backflow of washing water. Due to the small size of the pores, when the ozone pressure is low, its ability to allow gas to pass is limited, so that even when the device is not running the ozone generation program, a certain amount of gas can still be stored in the air storage chamber at all times. This part of the air pressure is sufficient to ensure that washing water will not be filled into the air storage chamber; but it is inevitable that washing water will penetrate into the air storage chamber through capillary phenomena over time. The annular step can prevent water droplets from flowing into the air guide tube after forming water droplets in the air storage chamber, thereby preventing water droplets from flowing into the ozone generator. In addition, when the washing device is not working, it can also prevent water from accumulating there, avoiding the hidden danger of bacterial contamination.

[0027] The present invention is further configured as follows: a plurality of ceramic gas-conducting layers are stacked in the gas storage cavity in a direction extending parallel to the top portion and leaving at least one gap with the seat portion in a circumferential position;

[0028] Preferably, the ceramic gas-conducting layer is made of a functional ceramic material having ozone activation performance.

[0029] Through the above design, the travel distance of ozone in the gas storage cavity can be further increased, the contact ability between ozone and functional ceramics can be increased, which is beneficial to increase the ionization degree of ozone molecules.

[0030] 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 mounting groove is connected to the air outlet device, so that the protrusions / grooves can be slidably embedded in the grooves / protrusions;

[0031] Preferably, the number of the correspondingly arranged grooves and protrusions is three, and the grooves and protrusions are evenly distributed along the connection between the air outlet device and the mounting groove;

[0032] Further preferably, the correspondingly arranged grooves and protrusions are both strip structures extending in the vertical direction;

[0033] Still more preferably, the cross-sections of the protrusions and the grooves are major arc surfaces of the same size;

[0034] More preferably, the hinging edge of the major arc surface is intersecting with the outer circumferential position of the air outlet device.

[0035] Through the above design, a reasonable connection between the air outlet device and the washing tank is achieved. The design of multiple protrusions / grooves can firmly connect the air outlet device and the washing tank, while avoiding relative rotation between the two, thereby avoiding the generation of gaps at the connection position. In addition, while achieving a stable connection between the air outlet device and the washing tank, the number of connecting parts is controlled as much as possible to avoid the connection structure being too complicated and not conducive to processing and production. It can also make the contact area between the grooves and protrusions at the connection larger, making the connection between the two more secure; and increasing the contact area between the connecting parts can avoid stress concentration when the two interact with each other, causing performance hazards.

[0036] The present invention is further configured as follows: the washing tank comprises an inner tank and an outer tank which are stacked, and a pre-dissolution chamber with a certain accommodating space is formed between the inner tank and the outer tank; the air outlet device is arranged on the mounting groove on the outer tank, and the upper end of the air outlet device faces the pre-dissolution chamber.

[0037] The above design improves the ozone dissolving capacity of the water tank washing equipment when forming ozone washing water. The pre-dissolving chamber is used to pre-dissolve and hold ozone washing water to prevent ozone washing water from mixing into ordinary washing water during ordinary washing. In actual use, the ozone generation function of the equipment can be started at the beginning of the washing program to generate ozone washing water, and the ozone washing water can be sprayed onto the tableware when disinfection washing is required. This operation method can prolong the diffusion time of ozone in washing water during the formation of ozone washing water and improve the solubility of ozone in washing water.

[0038] The present invention is further configured as follows: the inner tank is connected to the outer tank, so that the pre-dissolution chamber is connected to the washing chamber in the inner tank, and a filtering device is provided between the pre-dissolution chamber and the washing chamber.

[0039] Through the above design, the ozone washing water in the pre-dissolution chamber can flow more smoothly into the washing chamber, so that the tableware, fruits and vegetables can be soaked and cleaned with ozone washing water; and, when the washing device in the present technical solution is used in conjunction with the spraying device, the tableware, fruits and vegetables can be soaked and sprayed with 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 part of the ozone exists in the form of gas. The gaseous ozone will move upward in the washing equipment, so that the tableware, fruits and vegetables are immersed in the ozone atmosphere. The tableware, fruits and vegetables are sterilized and disinfected by gaseous ozone, which increases the ozone utilization rate of the washing equipment while also achieving coordination between multiple ozone disinfection methods and improving the disinfection efficiency.

[0040] The present invention is further configured as follows: the water tank type washing equipment comprises a spray device connected to the pre-dissolution chamber, the spray device draws ozone aqueous solution from the pre-dissolution chamber and sprays it into the inner tank for cleaning;

[0041] Preferably, there are multiple spray devices.

[0042] 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 caused by excessive residual food residues on the tableware in the initial stage of washing, which can be removed by conventional washing.

[0043] The present invention is further configured as follows: a one-way valve is provided on the air guide tube, and the one-way valve only allows gas to pass through.

[0044] Through the above design, it is possible to prevent washing water from flowing back into the ozone generator. The provision of the one-way valve greatly expands the structural applicability of the air duct. In this case, the air duct can be a pipe structure of any structure in the prior art.

[0045] The present invention is further configured such that: the sink-type washing device is a dishwasher.

[0046] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0047] 1. The technical solution in 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 kills bacteria by chemical reactions. 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 remove odors, truly realizing a "green" sterilization and disinfection process;

[0048] 2. The technical solution of the present invention can achieve a sealed connection between the air outlet device and the washing tank. Since both the air outlet device and the mounting groove can be made of rigid materials, the contact between the two is rigid contact, and there is likely to be a small gap at the matching point. The setting of the sealing device completely solves the above problem. The sealing device can be made of elastic material, such as rubber, silicone, etc. When the air outlet device and the washing tank are assembled, the pressure between the two causes the sealing device to undergo a certain degree of elastic deformation, thereby achieving a seal between the two.

[0049] 3. The technical solution of the present invention can guide the ozone gas from the air duct into the gas outlet device and then into the gas storage chamber. Since the gas storage chamber has a certain accommodation space, the ozone is gathered there and compressed to a certain extent to form ozone gas with a certain pressure, so that the ozone has a greater pressure and travel speed when it is ejected from the pore, which is conducive to the dissolution of ozone in the washing water. In addition, the setting of the gas storage chamber can increase the contact probability between the ozone gas and the functional ceramics, which is conducive to the ionization of ozone, thereby increasing the solubility of ozone.

[0061] 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.

[0063] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] Embodiment 1

[0065] like Figure 1 , Figure 2As shown, the water tank type washing equipment described in this embodiment includes: a washing tank 1, an ozone device; the ozone device includes an ozone generator 2, an air outlet device arranged on the washing tank 1, and an air duct 4 for connecting the air outlet device and the ozone generator 2; the lower end of the air outlet device is a middle-through lower connecting part 8, and the air outlet device is embedded in a mounting groove 9 with a through hole formed by the downward depression of the washing tank 1, and the through hole is arranged at the bottom of the mounting groove 9, and the lower connecting part 8 passes through the through hole to connect with the air duct 4. The air outlet device in this embodiment is positioned and connected with the mounting groove 9 through a connecting piece 10, and the lower connecting part 8 and the connecting piece 10 are provided with corresponding threads, and the connecting piece 10 is screwed with the lower connecting part on the lower side of the mounting groove 9. This structural design realizes a reasonable connection between the air outlet device and the washing tank 1, and the setting of the connecting piece can effectively connect the air outlet device and the washing tank 1 together, and position the two up and down to avoid relative movement between the two. The connection is a detachable connection. When the equipment needs to be assembled, disassembled, etc., the connection structure can flexibly realize the assembly and disassembly operations.

[0066] In this embodiment, a sealing device 11 is provided between the air outlet device and the mounting groove 1 to achieve sealing between the two; preferably, the sealing device 11 is a sealing gasket. This structural design can achieve a sealed connection between the air outlet device and the washing tank 1. Since both the air outlet device and the mounting groove 9 can be made of rigid materials, the contact between the two is rigid contact, and there is likely to be a small gap at the matching point. The provision of the sealing device 11 completely solves the above problem. The sealing device 11 can be made of elastic material, such as rubber, silicone, etc. When the air outlet device and the washing tank 1 are assembled, the pressure between the two causes the sealing device 11 to undergo a certain degree of elastic deformation, thereby achieving sealing between the two.

[0067] The air outlet device in this embodiment includes a seat 3 and a top 5 that are connected in a matching manner. The seat 3 is a through-tube structure. The lower end of the seat 3 is a lower connection part 8, and the upper end of the seat 3 is an upper connection part 14. The top 5 is embedded in the upper connection part 8 to achieve connection. When the ozone device starts working, a certain amount of washing water is first poured into the washing tank 1, and the ozone generator 2 starts to work to generate ozone. The ozone enters the seat 3 along the air guide pipe 4 and moves toward the top 5 along the through-tube structure of the seat 3. Finally, it is discharged into the washing water at a certain speed through the multiple air holes on the top 5, thereby forming ozone washing water. The density of the distribution of the air holes is greater than 10PPI; the multiple air holes are arranged periodically. This design can significantly reduce the volume of ozone bubbles overflowing the outlet device, thereby increasing the specific surface area of ​​ozone bubbles in contact with washing water, thereby increasing the solubility of ozone in washing water; the periodic distribution can ensure that the overflowing ozone bubbles are distributed as equidistantly as possible, avoiding mutual interference between ozone bubbles when moving in washing water, thereby avoiding excessive concentration of ozone bubbles and affecting the solubility of ozone. Preferably, the density value of the distribution of pores is one of 30PPI, 60PPI, 75PPI, 80PPI, and 90PPI. Among them, the pores not only have the function of spraying washing water into washing water, but also can prevent washing water from flowing back into the outlet device due to the small size of the pores.

[0068] Preferably, the gas outlet device is made of a functional ceramic material with ozone activation performance. Furthermore, an air storage chamber 12 with a certain accommodation space is formed between the top 5 and the seat 3. The ozone gas from the air duct 4 is introduced into the gas storage chamber 12 after passing through the gas outlet device. Since the gas storage chamber 12 has a certain accommodation space, the ozone is gathered there and compressed to a certain extent to form an ozone gas with a certain pressure, so that the ozone has a greater pressure and travel speed when it is ejected from the pore, which helps the ozone to dissolve in the washing water. In addition, the setting of the gas storage chamber can increase the contact probability between the ozone gas and the functional ceramics, which is beneficial to the ionization of ozone, thereby increasing the solubility of ozone.

[0069] Embodiment 2

[0070] like Figure 3As shown, the difference between this embodiment and the above embodiment is that the lower connecting portion 8 extends a certain distance into the gas storage chamber 12 to form an annular step 13. Preferably, the annular step 13 is integrated with the seat portion 3 of the gas outlet device to enhance the connection stability at this location and significantly increase the ease of molding and assembly. This structural design can also increase the ability of the gas outlet device to prevent backflow of washing water. Due to the small size of the pores, when the ozone pressure is low, its ability to allow gas to pass is limited, so that even when the device does not run the ozone generation program, the gas storage chamber 12 can still ensure that a certain amount of gas is stored at all times. This part of the gas pressure is sufficient to ensure that washing water will not be poured into the gas storage chamber; but it is inevitable that as time goes on, the washing water may penetrate into the gas storage chamber 12 through capillary phenomenon. The annular step 13 can prevent water droplets from flowing into the air duct after forming water droplets in the gas storage chamber 12, thereby preventing water droplets from flowing into the ozone generator.

[0071] In the water tank type washing equipment of this embodiment, an air storage cavity with a certain accommodation space is formed between the top and the seat. In the air storage cavity, a plurality of ceramic air guide layers are arranged in a stacked manner in a direction parallel to the top and have a gap with the seat in a circumferential position; through the above design, the travel distance of ozone in the air storage cavity can be further increased, the contact ability between ozone and functional ceramics can be increased, and the ionization degree of ozone molecules can be increased.

[0072] Embodiment 3

[0073] like Figure 4-Figure 7 As shown, the difference between this embodiment and the above embodiment is that: a plurality of protrusions 6 for connection are provided at the circumferential position on the outer side of the air outlet device, and a plurality of grooves 7 corresponding to the protrusions 6 are provided at the position where the mounting groove 9 is connected to the air outlet device, so that the protrusions 6 can be slidably embedded in the grooves 7; preferably, the number of the corresponding grooves 7 and protrusions 6 is three, and the grooves 7 and protrusions 6 are evenly distributed along the connection between the air outlet device and the mounting groove 9; this design realizes a reasonable connection between the air outlet device and the washing tank 1, and the design of multiple protrusions 6 / grooves 7 can firmly connect the air outlet device and the washing tank 1, and can also avoid relative rotation between the two, thereby avoiding the generation of gaps at the connection position. In addition, while realizing a stable connection between the air outlet device and the washing tank 1, this structure controls the number of connecting components as much as possible to avoid the connection structure being too complicated and not conducive to processing and production.

[0074] Further preferably, the corresponding grooves 7 and protrusions 6 are both strip structures extending in the vertical direction; through the above design, the contact area between the grooves 7 and protrusions 6 at the connection can be made larger, making the connection between the two more secure; and increasing the contact area between the connecting parts can avoid stress concentration when the two interact with each other, causing performance hazards. In addition, the size of the air outlet device is relatively small compared to the washing tank 1, and the structure of the protrusion 6 arranged on it is relatively simple, and the processing accuracy can be guaranteed, so that the connection structure between the air outlet device and the washing tank 1 has a higher dimensional matching performance, further improving the connection performance between the two.

[0075] Further preferably, the cross-sections of the protrusion 6 and the groove 7 are major arc surfaces of the same size; and the ridge of the major arc surface is intersecting with the outer circumferential position of the air outlet device. This structural design can greatly reduce the complexity of the structure of the connection, facilitate production and processing; and can improve the connection performance between the connecting parts, so that the sliding between the air outlet device and the washing tank 1 is smoother during assembly.

[0076] In this embodiment, the protrusion 6 and the groove 7 at the connection between the air outlet device and the installation groove 9 can also be interchanged to match the connection relationship between components of different sizes and expand the scope of application of the component matching method.

[0077] Embodiment 4

[0078] The difference between this embodiment and the above-mentioned embodiments is that the water tank type washing equipment described in this embodiment includes: a washing tank, an ozone device, the washing tank is used to wash dishes, fruits and vegetables, the ozone device is connected to the washing tank, and is used to form ozone washing water; the washing tank includes an inner tank and an outer tank arranged in a stacked manner; a pre-dissolving chamber with a certain accommodation space is formed between the inner tank and the outer tank, and the pre-dissolving chamber is used to pre-dissolve and hold ozone washing water. The inner tank is connected to the outer tank, so that the pre-dissolving chamber is connected to the washing chamber in the inner tank, and a filtering device is provided between the pre-dissolving chamber and the washing chamber. The ozone device includes an ozone generator, an air outlet device arranged on the outer tank and with the top facing the pre-dissolving chamber, and an air duct for connecting the air outlet device and the ozone generator. Preferably, the air outlet device is arranged at the bottom of the outer tank, and its air outlet portion faces upward. This design allows the ozone washing water in the pre-dissolution chamber to flow more smoothly into the washing chamber, so that the ozone washing water can be used to soak and wash the tableware, fruits and vegetables; and, when the washing device in this embodiment is used in conjunction with the spray device, the tableware, fruits and vegetables can be washed 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 part of the ozone exists in the form of gas. The gaseous ozone will move upward in the washing equipment, so that the tableware, fruits and vegetables are immersed in the ozone atmosphere. The tableware, fruits and vegetables are sterilized and disinfected by gaseous ozone, which increases the ozone utilization rate of the washing equipment and realizes the coordination between multiple ozone disinfection methods, thereby improving the disinfection efficiency. The technical solution in this embodiment enables the sink-type washing equipment to realize the function of disinfection with ozone gas alone. Users can choose to disinfect only the tableware, fruits and vegetables without washing them according to their needs. For example, even if maternal and infant products need to be cleaned regularly after use, they still need to be disinfected before they can be used again. The technical solution in this embodiment completely solves this technical problem. Only ozone gas is used to disinfect tableware, fruits and vegetables without wetting their surfaces. This disinfection method can keep the surface of the utensils clean and dry, which is convenient for the storage and packaging of utensils. Some items, such as baby bottles, need to be packaged and carried immediately after disinfection. The improvement of their surface dryness and cleanliness is conducive to improving user experience. The technical solution in this embodiment is fully applicable to such situations.

[0079] Embodiment 5

[0080] The difference between this embodiment and the above embodiment is that: the washing tank includes an inner tank and an outer tank arranged in a stacked manner, and the outer tank wraps the inner tank below and around; a pre-dissolution chamber with a certain accommodation space is formed between the inner tank and the outer tank; the gas outlet device is arranged on the mounting groove on the outer tank, and the upper end of the gas outlet device faces the pre-dissolution chamber. The water tank type washing equipment includes a spray device connected to the pre-dissolution chamber, and the spray device draws ozone water solution from the pre-dissolution chamber and sprays it into the inner tank for cleaning. The pre-dissolution chamber is used to pre-dissolve and hold ozone washing water to prevent ozone washing water from mixing into ordinary washing water during ordinary washing; in actual use, the ozone generation function of the equipment can be started at the beginning of the washing program to generate ozone washing water, and the ozone washing water can be sprayed onto the tableware when disinfection washing is required. This operation mode can prolong the diffusion time of ozone in washing water during the formation of ozone washing water, and improve the solubility of ozone in washing water. When the equipment is used, the ozone washing water spraying operation is performed only when disinfection is required, so as to avoid the waste of the cleaning ability of the ozone washing water caused by the excessive residual food residues on the tableware in the initial stage of washing, which can be removed by conventional washing. In addition, the design of the spraying device can evenly spray the ozone washing water on the tableware, fruits and vegetables, improve the utilization rate of the ozone washing water, and avoid waste. At the same time, the spraying washing method can make the ozone washing water form small droplets, reduce the solubility of ozone in the washing water, improve the ozone release capacity of the ozone washing water, give full play to the disinfection function of ozone, and improve the utilization rate of ozone; on the other hand, increasing the ozone consumption rate can also avoid residual ozone or ozone aqueous solution in the washing tank after washing. Obviously, if the ozone residue is released into the kitchen air, it is harmful to the human body. The technical solution in this embodiment completely solves this problem. The spraying device in this embodiment can be multiple, and the multiple spraying devices have different spraying positions for tableware, fruits and vegetables, so that the sink-type washing equipment can clean and disinfect the items to be cleaned from multiple angles, which is conducive to improving the working efficiency and use effect of the equipment.

[0081] The top of the gas outlet device in this embodiment has the same curvature as the inner surface of the outer tank, so that the two form a smooth transition surface after installation. This design makes the gas outlet device not protrude from the inner surface of the outer tank, and the fluidity of the ozone washing water will not be affected by the uneven structure in the pre-dissolving chamber when the ozone washing water is pre-dissolved in the pre-dissolving chamber, thereby avoiding affecting the solubility of ozone in the ozone washing water.

[0082] The sink-type washing equipment in the above-mentioned embodiments may be a sink-type dishwasher.

[0083] The technical solution in 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 tableware. At the same time, it can also remove pesticide residues on fruits and vegetables and remove odors, truly realizing a "green" sterilization and disinfection process; the position of the gas outlet device is more reasonably set. Ozone has a lower density than washing water. Setting the gas outlet device at the bottom of the outer tank can significantly increase the dissolution stroke of ozone bubbles in washing water, increase the contact probability of ozone bubbles with water, and thus improve the solubility of ozone; it can significantly reduce the volume of ozone bubbles overflowing the gas outlet device, thereby increasing the specific surface area of ​​ozone bubbles in contact with washing water, and thereby increasing the solubility of ozone in washing water; the periodic distribution can ensure that the overflowing ozone bubbles are distributed as equidistantly as possible, avoiding mutual interference between ozone bubbles when moving in washing water, and thus avoiding the ozone bubbles being too concentrated and affecting the solubility of ozone.

[0084] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
