Description

Technical Field

[0001] This invention relates to a cabinet, specifically a cabinet that uses ozone to clean tableware. Background Technology

[0002] After washing dishes with dish soap, surfactants, fragrances, pigments, and organic preservatives will remain on the surface of the dishes. If these substances remain on the dishes for a long time, they will enter the human body with food and accumulate in the body over time, affecting human health.

[0003] In existing technologies, after washing dishes with dish soap, they are generally diluted with a large amount of water, but some of the aforementioned harmful substances inevitably remain. In restaurants, central kitchens, and other similar settings, the fast pace of dining often leads to a reduction in the time spent washing tableware, increasing the risk of harmful substance residue. Therefore, the industry urgently needs a tableware cleaning method that can quickly remove these harmful substances. Summary of the Invention

[0004] The purpose of this invention is to provide a cabinet that uses ozone to clean tableware, which can efficiently and quickly remove dish soap residue.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A cabinet for purifying tableware with ozone includes a cabinet body. The top wall of the cabinet body has a washing tank and a cleaning tank. The inside of the cabinet body has a sealed dissolved gas chamber. The cleaning tank is located in the sealed dissolved gas chamber. The bottom wall of the sealed dissolved gas chamber is equipped with several aeration heads. The cabinet body is equipped with an ozone circulation pump. The ozone circulation pump is connected to an ozone generator through an air inlet pipe. The ozone circulation pump is connected to the aeration heads through an air inlet pipe. The ozone circulation pump is connected to the part above the liquid surface of the sealed dissolved gas chamber through a return air pipe. The cleaning tank is connected to a liquid extraction pipe, which is located in the sealed dissolved gas chamber. The cleaning tank is equipped with a drain pipe. A plate placement slot is provided at the upper opening of the cleaning tank. A drive chain is provided below the plate placement slot. The drive chain is connected to multiple chain links. The cross-section of the chain links is L-shaped. The movement trajectory of the chain links is below the plate placement slot.

[0006] Specifically, the clean tank is rectangular in shape, and angle steel plates are fixed to both sides of the upper opening of the clean tank. The cross-section of the angle steel plates is in the shape of two steps. The inner convex corner of the angle steel plates is provided with a placement notch. The two placement notches provided by the two angle steel plates together form the plate placement groove. A limiting plate is fixed to the outside of the placement notch.

[0007] Specifically, two sprockets are provided on both sides of the opening of the clean tank, and a drive chain is wound around the two sprockets on the same side, with the drive chain being inclined.

[0008] Specifically, the notch is placed at an angle, and the angle between the extension direction of the notch and the horizontal plane is 2°-4°.

[0009] Specifically, the upper section of the transmission chain moves from bottom to top, and the lower edge of the chain link is provided with an upwardly bent actuating piece.

[0010] Specifically, a sealed mounting cavity is provided at the opening of the clean tank, and a drive motor is provided inside the sealed mounting cavity to drive the transmission chain.

[0011] Specifically, the bottom of the sealed dissolved air chamber is equipped with four aeration heads, which are arranged in a rectangular array.

[0012] Specifically, the suction pipe is connected to an electric suction pump, and the discharge pipe is connected to an electric discharge pump.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: An electric pump draws a liquid with high ozone solubility into a cleaning tank, submerging all chain links (and simultaneously the actuating plates). The drive motor then moves the transmission chain, causing the upper section of the chain to move in direction A. This causes the actuating plates to propel the water flow in direction A, thus rinsing the inner walls of the dishes. The liquid with high ozone solubility oxidizes and decomposes surfactants, fragrances, pigments, and organic preservatives remaining on the inner walls of the dishes, achieving efficient and rapid removal of detergent residue and protecting human health.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] See Figures 1 to 3 A cabinet for purifying tableware with ozone includes a cabinet body with a washing tank 1 and a cleaning tank 2 on the top wall. A sealed dissolved gas chamber 3 is located inside the cabinet body, and the cleaning tank 2 is situated within the sealed dissolved gas chamber 3. Several aeration heads 31 are provided on the bottom wall of the sealed dissolved gas chamber 3. The cabinet body is equipped with an ozone circulation pump 32, which is connected to an ozone generator (not shown) via an air inlet pipe 35. The ozone circulation pump 32 is connected to the aeration heads 31 via an air inlet pipe 33. The ozone circulation pump 32 is connected to the portion of the sealed dissolved gas chamber 3 above the liquid surface via a return air pipe 34.

[0019] See Figure 3 The clean tank 2 is connected to a liquid extraction pipe 21, which is located inside the sealed dissolved gas chamber 3. The clean tank 2 is equipped with a drain pipe 23. (See...) Figure 2 , Figure 5 The clean tank 2 has a tray placement slot at its upper opening. A drive chain 26 is located below the tray placement slot, and the drive chain 26 is connected to multiple chain links 27. The cross-section of each chain link 27 is L-shaped (combined with...). Figure 7 The movement trajectory of link 27 is below the plate placement slot.

[0020] Specifically, the clean tank 2 is rectangular in shape, and angle steel plates 25 are fixed to both sides of the upper opening of the clean tank 2 (see...). Figure 6 The angle steel sheet 25 has a two-step cross-section, and the inner convex corner of the angle steel sheet 25 has a placement notch 251. The two placement notches 251 of the two angle steel sheets 25 together form the plate placement groove. A limiting piece 252 is fixedly connected to the outside of the placement notch 251.

[0021] Specifically, see Figure 5 , Figure 6 Two sprockets are provided on both sides of the opening of the clean tank 2. The two sprockets on the same side are wound with a transmission chain 26, which is inclined.

[0022] Specifically, in combination Figure 5 The notch 251 is set at an angle, and the angle between the extension direction of the notch 251 and the horizontal plane is 2°-4°.

[0023] Specifically, the upper section of the transmission chain 26 moves from bottom to top. Figure 5 In the middle direction (A), the lower edge of link 27 is provided with an upwardly bent actuating piece 271.

[0024] Specifically, a sealed mounting cavity 28 is provided at the opening of the clean tank 2, and a drive motor 281 is provided inside the sealed mounting cavity 28. The drive motor 281 is used to drive the transmission chain 26 to move.

[0025] Specifically, the bottom of the sealed dissolved air chamber 3 is provided with four aeration heads 31, which are arranged in a rectangular array.

[0026] Specifically, the suction pipe 21 is connected to an electric suction pump 22, and the discharge pipe 23 is connected to an electric discharge pump 24.

[0027] The working principle of this invention is as follows: See Figure 1 After the meal, wash the dishes in the washing tank 1. Dish soap will be used in the process. After washing, rinse the dishes with clean water to remove the foam.

[0028] Next, arrange the bowls and plates according to their depth, either to the left or right of the plate holder, such as... Figure 5 As shown, deeper cutlery (such as large bowls) is placed on the right side of the plate placement slot, while shallower cutlery (such as plates) is placed on the left side. The plate placement slot is formed by two placement notches 251 provided in two angle steel plates 25 located on either side of the opening of the clean tank 2 (in conjunction with...). Figure 5 , Figure 6 The two sides of the bowl and plate are supported by two placement notches 251, while the two limiting pieces 252 on both sides restrict the lateral movement of the bowl and plate, ensuring that the bowl and plate are always on the two placement notches 251.

[0029] Subsequently, clean water is injected into the sealed dissolved air chamber 3 through the inlet and outlet until the water level is higher than the inlet end of the aeration head 31 and the liquid extraction pipe 21. During the water injection process, the air valve (not shown in the figure) of the sealed dissolved air chamber 3 is in the open state, so that the air inside the sealed dissolved air chamber 3 can be discharged as the water level rises.

[0030] Subsequently, an ozone generator (not shown in the figure) produces ozone, which is then transmitted through inlet pipe 35 (see...). Figure 1The ozone is input to the ozone circulation pump 32, which further pumps the ozone to each aeration head 31, maximizing the dissolution of ozone in the liquid stored in the sealed dissolved air chamber 3. Since ozone has low solubility (approximately 13 times that of oxygen) and ozone dissolved in water gradually decomposes after 20-30 minutes, to ensure the highest possible ozone solubility in the liquid within the sealed dissolved air chamber 3, during the process of the ozone circulation pump 32 pumping ozone to the aeration heads 31, the air above the liquid surface in the sealed dissolved air chamber 3 (containing undissolved ozone) is drawn back to the ozone circulation pump 32 through the return air pipe 34 and subsequently pumped back to the aeration heads 31. This cycle repeats continuously to ensure the highest possible ozone solubility in the liquid within the sealed dissolved air chamber 3. During this process, the ventilation valve (not shown in the figure) of the sealed dissolved gas chamber 3 is in the closed state to prevent ozone from overflowing. At the same time, the pressure gauge in the sealed dissolved gas chamber 3 monitors the pressure of the sealed dissolved gas chamber 3 and controls the ozone pumping rate in a timely manner.

[0031] Subsequently, the electric pump 22 draws the liquid with high ozone solubility into the clean tank 2, causing the liquid level in the clean tank 2 to submerge each chain link 27 (and simultaneously submerge the actuating plate 271). Then, the drive motor 281 drives the transmission chain 26 to move, causing the upper section of the transmission chain 26 to move along... Figure 5 The water moves in the direction A, causing each actuating piece 271 to move the water flow along the direction A, thereby rinsing the inner wall of the dishes. The liquid with high ozone solubility oxidizes and decomposes surfactants, fragrances, pigments and organic preservatives remaining on the inner wall of the dishes, thereby achieving efficient and quick removal of detergent residue and protecting human health.

[0032] As mentioned above, Figure 5 As shown, deeper cutlery (such as large bowls) is placed on the right side of the plate slot, while shallower cutlery (such as plates) is placed on the left side. This is to allow the inner walls of deeper cutlery (such as large bowls) to be more thoroughly immersed in the liquid, thus achieving a more complete cleaning and ensuring thorough cleaning without any blind spots.

[0033] During the ozone cleaning process of tableware, the electric drain pump 24 can be controlled in a timely manner to drain the liquid with reduced ozone solubility in the clean tank 2, and the electric pump 22 can be used to pump new liquid with high ozone solubility into the clean tank 2 to ensure that the cleaning process is continuously effective.

[0034] The drive chain 26, chain link 27, and all parts that come into contact with water in this cabinet are made of 316 stainless steel.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
