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 deficiencies of the prior art, and provide a water tank type washing equipment, comprising: a washing tank, an ozone device, the washing tank comprising an inner tank and an outer tank arranged in a stacked manner, a pre-dissolution chamber with a certain accommodation space formed between the inner tank and the outer tank; the ozone device comprises an ozone generator, an air outlet device arranged on the outer tank and with the top facing the pre-dissolution chamber, and an air duct for connecting the air outlet device and the ozone generator. The water tank type washing equipment in the present invention can improve the solubility of ozone in washing water to a large extent by reasonably arranging the position of the air outlet device in the washing equipment, increase the ozone content in the ozone washing water, and thus significantly improve the sterilization ability of the ozone washing water. The water tank type washing equipment can be a water tank type dishwasher. The interior of the inner tank is a washing chamber.

[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 washing equipment, comprising: a washing tank, an ozone device, the washing tank comprising an inner tank and an outer tank arranged in a stacked manner, a pre-dissolution chamber with a certain accommodation space formed between the inner tank and the outer tank; the ozone device comprises an ozone generator, an air outlet device arranged on the outer tank and with the top facing the pre-dissolution chamber, and an air guide pipe for connecting the air outlet device and the ozone generator. The pre-dissolution chamber is used for pre-dissolving and containing ozone washing water.

[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 outer tank and embedded therein;

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] The present invention is further configured as follows: a plurality of air holes for gas to pass through are provided at the top of the air outlet device;

[0014] Preferably, the plurality of pores are arranged periodically.

[0015] The present invention is further configured such that the density of the pore distribution at the top of the air outlet device is greater than 10PPI.

[0016] Through the above design, the size of the pores is reduced, which can significantly reduce the volume of ozone bubbles overflowing the outlet device, thereby increasing the specific surface area of ​​the ozone bubbles in contact with the washing water and increasing the solubility of ozone in the washing water; the periodic distribution of the pores can ensure that the overflowing ozone bubbles are distributed as equidistantly as possible, avoiding mutual interference between the ozone bubbles when moving in the washing water, thereby avoiding the ozone bubbles being too concentrated and affecting the solubility of ozone. As for the undissolved ozone, the above technical solution can keep it well dispersed when it enters the washing tank, making it easy to exert the disinfection ability of ozone.

[0017] The present invention is further configured as follows: the gas outlet device is made of ceramic material;

[0018] Preferably, the gas outlet device is made of a functional ceramic material having ozone activation performance.

[0019] The above design improves the problem of ozone dissolution. If ozone is directly introduced into water through an outlet device, ozone is not easily soluble in water. In the present invention, a ceramic outlet device structure is added so that the ozone generated by the ozone generator can be better dissolved in water. When ozone contacts washing water in molecular form, its solubility is limited. Functional ceramics with ozone activation properties can activate ozone molecules in contact with it into ozone ions. Obviously, the solubility of ozone ions in washing water is higher than that of ozone molecules. This technical solution helps to further improve the solubility of ozone in washing water.

[0020] 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;

[0021] Preferably, there are multiple one-way valves.

[0022] 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.

[0023] The present invention is further configured as follows: the water tank type washing equipment includes a spray device connected to the pre-dissolution chamber, the spray device draws ozone washing water solution from the pre-dissolution chamber and sprays it into the inner tank for washing operation;

[0024] Preferably, there are multiple spray devices.

[0025] The above design can achieve the separation of ozone washing water and washing water. When the equipment is in use, the ozone washing water spraying operation is performed only when disinfection is required, so as to avoid the phenomenon that too much food residue is left on the tableware in the early stage of washing, which can be removed by conventional washing and wastes the cleaning ability of ozone washing water.

[0026] 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.

[0027] Through the above design, the gas outlet device does not protrude from the inner surface of the outer tank. When the ozone washing water is pre-dissolved in the pre-dissolution chamber, the fluidity of the ozone washing water will not be affected by the uneven structure in the pre-dissolution chamber, thereby avoiding affecting the solubility of ozone in the ozone washing water.

[0028] 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.

[0029] Through the above design, the solubility of ozone in ozone washing water can be further improved.

[0030] The present invention is further configured as follows: a plurality of protrusions / grooves for connection are provided at the circumferential position of the outer side of the gas outlet device, and a plurality of grooves / protrusions corresponding to the protrusions / grooves are provided at the position where the outer groove is connected to the gas 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 outer 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: a sealing device is provided between the gas outlet device and the outer groove to achieve sealing between the two;

[0037] Preferably, the sealing device is a sealing gasket.

[0038] The present invention is further configured as follows: the gas outlet device comprises a seat portion and a top portion which are matched and connected, the seat portion is a through 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; the top portion is provided with an air hole for gas to pass through;

[0039] Preferably, the connection between the top and the upper connecting portion is a threaded connection;

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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;

[0047] Preferably, the ceramic gas-conducting layer is made of a functional ceramic material having ozone activation performance.

[0048] 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.

[0049] The present invention is further configured as follows: one end of the air outlet device connected to the air guide pipe is a connecting part, the connecting part passes through the outer groove, and is connected to the connecting piece on the other side of the outer groove to realize the positioning of the air outlet device and the outer groove; preferably, a matching threaded structure is provided at the connection between the connecting part and the connecting piece to realize the connection between the two. On the other hand, when the structural design matches the protrusion and groove structure of the air outlet device and the outer groove, the protrusion and groove structure can also provide a positioning function for the air outlet device in the circumferential direction of the air outlet device, so that when assembling the air outlet device, it is only necessary to put the air outlet device in the right position, and then screw the connecting part and the connecting piece together. When screwing together, the user does not need to fix the top of the air outlet device manually or through other auxiliary tools. The user only needs to rotate the connecting piece to complete the operation without performing other auxiliary operations. Especially when the size of the washing tank is designed to be deeper, it is difficult for the user to position the connecting parts on both sides of the washing tank. It can be seen that the cooperation between the structures can significantly increase the assembly performance between the parts and simplify the assembly and disassembly operations.

[0050] The present invention is further configured such that: the sink-type washing device is a dishwasher.

[0051] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0052] 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;

[0053] 2. The technical solution of the present invention sets the position of the gas outlet device 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 process of ozone bubbles in washing water, increase the contact probability of ozone bubbles with water, and thus improve the solubility of ozone;

[0054] 3. The technical solution of the present invention can significantly reduce the volume of ozone bubbles overflowing the exhaust device, 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; the periodic distribution can ensure that the overflowing ozone bubbles are distributed as equidistantly as possible, avoiding mutual interference between the ozone bubbles when moving in the washing water, thereby avoiding the ozone bubbles being too concentrated and affecting the solubility of ozone.

[0064] 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.

[0065] Embodiment 1

[0066] The water tank type washing equipment described in this embodiment includes: a washing tank and an ozone device. The washing tank is used to wash dishes, fruits and vegetables. The ozone device is connected to the washing tank to form ozone washing water. The washing tank includes an inner tank and an outer tank stacked together. 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 enables the ozone washing water in the pre-dissolving chamber to flow more smoothly into the washing chamber, so as to realize the soaking and washing of tableware, fruits and vegetables with ozone washing water; and, when the washing device in this embodiment is used in conjunction with the spraying device, the tableware, fruits and vegetables can be soaked and sprayed with ozone washing water at the same time. 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, and the gaseous ozone will move upward in the washing equipment, so that the tableware, fruits and vegetables are immersed in the ozone atmosphere, and the tableware, fruits and vegetables are sterilized and disinfected by gaseous ozone, which increases the ozone utilization rate of the washing equipment, and also 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 tableware, fruits and vegetables without washing them according to their needs. For example, even if maternal and child products need to be cleaned in time after use, they still need to be disinfected before they can be used again. The technical solution in this embodiment completely solves this problem. Using only ozone gas to disinfect tableware, fruits and vegetables will not wet their surfaces. This disinfection method can keep the surfaces of utensils clean and dry, making it easier to store and package the utensils. Some items, such as baby bottles, need to be packaged and carried immediately after disinfection. Improving the dryness and cleanliness of their surfaces is conducive to improving user experience. The technical solution in this embodiment is fully applicable to such situations.

[0067] Embodiment 2

[0068] like Figure 1 , Figure 2 , Figure 3As shown, the sink-type washing device described in this embodiment is different from the above-mentioned embodiment in that: the sink-type washing device includes: a washing tank, an ozone device, the washing tank is used to wash dishes, fruits and vegetables, and the ozone device is connected to the washing tank to form ozone washing water; the washing tank includes an inner tank (not shown in the figure) and an outer tank 1 which are stacked; the outer tank 1 wraps the inner tank below and around; a pre-dissolving chamber ( Figure 3 The upper side position of the pre-dissolving chamber, not marked in the figure), the pre-dissolving chamber is used for pre-dissolving and holding ozone washing water, and the pre-dissolving chamber is not directly connected to the washing chamber to prevent the ozone washing water from mixing into the 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 on the tableware when disinfection and washing are required. This operation mode can prolong the diffusion time of ozone in the washing water during the formation of ozone washing water and improve the solubility of ozone in the washing water; the ozone device includes an ozone generator 2, an air outlet device 3 arranged on the outer tank 1 and with the top facing the pre-dissolving chamber, and an air duct 4 for connecting the air outlet device 3 and the ozone generator 2. In the formation process of ozone washing water, a certain amount of washing water needs to be poured into the pre-dissolving chamber, and the ozone generator 2 starts to work to generate ozone, and the ozone enters the air outlet device 3 along the air duct 4, and is sprayed into the washing water in the pre-dissolving chamber from the top 5 of the air outlet device.

[0069] The gas outlet device 3 in this embodiment is arranged at the bottom of the outer tank 1 and embedded therein. The outer tank 1 surrounds and fixes the gas outlet device 3 on all sides to achieve the connection between the two. The top 5 of the gas outlet device is consistent with the curvature of the inner surface of the outer tank 1, 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-dissolution chamber when the ozone washing water is pre-dissolved in the pre-dissolution chamber, thereby avoiding affecting the solubility of ozone in the ozone washing water.

[0070] Embodiment 3

[0071] The difference between the water tank type washing equipment described in this embodiment and the above embodiment is that: the gas outlet device includes a seat and a top (located at the top of the gas outlet device) that are matched and connected, the seat is a through tubular structure, the lower end of the seat is a lower connection part, the upper end of the seat is an upper connection part, and the top is embedded in the upper connection part to achieve connection; the connection between the top and the upper connection part is a threaded connection; there are multiple air holes for gas to pass through; preferably, the multiple air holes are arranged periodically. The density of the air hole distribution is greater than 10PPI. This design can significantly reduce the volume of ozone bubbles overflowing the gas outlet device, thereby increasing the specific surface area of ​​the ozone bubbles in contact with the washing water, and increasing the solubility of ozone in the washing water; the periodic distribution of the air holes can ensure that the overflowing ozone bubbles are distributed as equidistantly as possible, avoiding mutual interference between the ozone bubbles when moving in the washing water, and thus avoiding the ozone bubbles from being too concentrated and affecting the solubility of ozone. Preferably, the density value of the air hole distribution is 30PPI, 60PPI, 75PPI, 80PPI, 90PPI.

[0072] The gas outlet device in this embodiment is made of ceramic material; preferably, the gas outlet device is made of functional ceramic material with ozone activation performance. This design improves the solubility problem of ozone. If ozone is directly passed into water, ozone is not easily soluble in water. In the present invention, the structure of the ceramic gas outlet device is improved so that the ozone generated by the ozone generator can be better dissolved in water. When ozone contacts washing water in molecular form, its solubility is limited. Functional ceramics with ozone activation performance can activate ozone molecules in contact with it into ozone ions. Obviously, the solubility of ozone ions in washing water is higher than that of ozone molecules. This technical solution helps to further improve the solubility of ozone in washing water. In addition, ceramics have strong high temperature resistance, and even if used for a long time in a high temperature environment, there will be no changes in structure and performance. That is to say, the water tank type washing equipment in this embodiment can also add a heating device to increase the temperature of the washing water, and the improvement of adding the heating device will not affect the structural performance of the ceramic gas outlet device.

[0073] 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.

[0074] In the water tank type washing equipment of this embodiment, the number of the gas outlet devices is multiple, and the multiple gas outlet devices are distributed at the bottom of the outer tank. This design enables the ozone device to release ozone at multiple points, improves the ozone release environment from a macro perspective, increases the contact probability of ozone and washing water, and thus improves the solubility of ozone. In addition, this technical solution can increase the speed of ozone dissolving in washing water, improve the generation efficiency of ozone washing water, and is suitable for washing environments with large ozone washing water consumption.

[0075] Embodiment 4

[0076] The difference between the sink type washing equipment described in this embodiment and the above embodiment is that: a one-way valve is provided on the air guide pipe, and the one-way valve only allows gas to pass through. Through the above design, it is possible to prevent washing water from flowing back into the ozone generator. The setting of the one-way valve greatly expands the applicable scope of the structure of the air guide pipe. In this case, the air guide pipe can be a pipe of any structure in the prior art.

[0077] The water tank washing equipment in this embodiment includes a spray device connected to the pre-dissolution chamber, and the spray device draws ozone washing water solution from the pre-dissolution chamber and sprays it into the inner tank for cleaning. 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, avoiding the phenomenon that the cleaning ability of ozone washing water is wasted on the dirt that can be removed by conventional washing due to excessive food residues on the tableware in the early stage of washing. In addition, the design of the spray device can evenly spray ozone washing water on tableware, fruits and vegetables, improve the utilization rate of ozone washing water, and avoid waste. At the same time, the spray 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 solution in the washing tank after washing. Obviously, if the residual ozone is released into the kitchen air, it is harmful to the human body. The technical solution in this embodiment completely solves this problem.

[0078] There may be multiple spray devices in this embodiment, and the multiple spray devices have different spray positions and methods 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 beneficial to improving the working efficiency and use effect of the equipment.

[0079] The sink-type washing equipment in the above-mentioned embodiments may be a sink-type dishwasher.

[0080] 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.
