[0038] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention, so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0039] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature, or it may be indirectly fixed or connected to the other feature. In addition, the descriptions of up, down, left, right, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the drawings.

[0040] Reference Figures 1 to 8 A turning type tableware cleaning device comprises a shell 1 and a recovery conveying mechanism 2, a cleaning conveying mechanism 3, a spraying device 4 and a control device (not shown in the figure) arranged in the shell 1.

[0041] The control device is electrically connected to the recovery conveying mechanism 2, the cleaning conveying mechanism 3, and the pumping mechanism respectively to control the operation of each mechanism of the equipment. The control device can be a single chip microcomputer or a PLC.

[0042] The recovery conveying mechanism 2 is provided with an inclined first conveying surface for conveying the tableware to be cleaned put in by the customer.

[0043] The recovery conveying mechanism 2 is specifically a first conveying mesh belt device that is tilted, with an inclination of 30° to 60°, preferably 45°. The first conveying mesh belt device includes two conveying rollers at the head and tail, a conveying mesh belt that is tensioned on the two conveying rollers, and a motor that drives the conveying rollers to rotate. A roller motor can also be used for driving, and one of the conveying rollers can be replaced by a roller motor, which can maintain its power and reduce the space occupied by the motor, further reducing the volume of the device. The conveying surface of the first conveying mesh belt device is the first conveying surface.

[0044] The first conveyor belt device is provided with angle supports 8 at both ends. Figure 4 The angle support 8 is provided throughout the entire length, and the cross section of the angle support 8 is at a right angle. The mesh belt of the first conveyor mesh belt device can be slidably mounted on the angle support 8; the front and rear end surfaces of the angle support 8 are fixedly connected to the housing 1. The angle support 8 is used to support the first conveyor mesh belt to prevent the first conveyor mesh belt from falling and deforming in the middle due to weight, and because the mesh belt is made of stainless steel, it can persist in sliding and rubbing with the angle support 8 for a long time without breaking.

[0045] The shell 1 is provided with a tableware recovery port 11 corresponding to the first conveying surface, so that the tableware put in by the guest falls directly on the conveying mesh belt of the first conveying mesh belt device, and enters the cleaning conveying mechanism 3 with the operation of the conveying mesh belt.

[0046] Wherein, the cleaning and conveying mechanism 3 is provided with an arc-shaped conveying surface and a second conveying surface.

[0047] The arc-shaped conveying surface is in the shape of a semi-conical slope, the inclination angle of which is equal to the inclination angle of the first conveying mesh belt device. One end of the arc-shaped conveying surface is connected and tangent to the outlet end of the first conveying surface, and the other end of the arc-shaped conveying surface is connected to the inlet end of the second conveying surface.

[0048] The second conveying surface is arranged obliquely, and a conveying direction of the second conveying surface is opposite to a conveying direction of the first conveying surface.

[0049] The tableware transported by the first conveying surface enters the arc-shaped conveying surface, and is further transported by the arc-shaped conveying surface to the second conveying surface. During the process of being transported by the arc-shaped conveying surface and the second conveying surface, the tableware is also sprayed and cleaned by the spray device 4.

[0050] Among them, the spray device 4 includes a plurality of sprayers respectively arranged on the arc-shaped conveying surface, below the second conveying surface and on the side thereof, and a pumping mechanism for supplying water to the sprayers. The arc-shaped conveying surface and the second conveying surface are both provided with openings for the sprayers to spray. The openings may be the gaps between the meshes of the conveying mesh belt and the conveying rollers. The high-pressure water jets sprayed by the sprayers pass through the openings to rinse and clean the tableware on the arc-shaped conveying surface and the second conveying surface.

[0051] The housing 1 is provided with a tableware discharge port 12 at the outlet end corresponding to the second conveying surface, and the tableware cleaned by the sprayer while being conveyed is discharged from the tableware discharge port 12 .

[0052] The specific usage process is: after the guests have finished their meal, they put the tableware from the tableware recovery port 11 onto the first conveying surface, which is then transported from the first conveying surface into the curved conveying surface and then makes a 180° turn along the curved conveying surface to enter the second conveying surface. During transportation, the tableware is sprayed and cleaned by the sprayer and finally discharged from the tableware discharge port 12. The entire process does not require additional manpower to recover and transport the tableware.

[0053] In this process, the tableware enters the curved conveying surface from the first conveying surface and then enters the second conveying surface from the curved conveying surface. At this time, the conveying direction of the tableware is flipped 180° compared with the first conveying surface. Overall, it is equivalent to folding the existing large-scale tableware washing device in half, effectively shortening the overall length of the device, so that it can be used in small restaurants. Due to the setting of the tableware recovery and conveying mechanism 2, the tableware can be directly recovered without setting up additional tableware recovery points or spending a lot of manpower on tableware transportation.

[0054] In the present invention, the cleaning and conveying mechanism 3 includes a first conveying roller device 31 and a second conveying mesh belt device 32 .

[0055] The first conveying roller device 31 includes a plurality of first rollers 311 evenly distributed within a range of 180° around the same axis and a first roller 311 driving device for driving the first rollers 311 to rotate, and of course, a supporting frame for mounting each first roller 311 and a transmission gear between two adjacent first rollers 311. The first roller 311 driving device can use a roller motor and replace one of the first rollers 311. In this solution, the rotation direction of each first roller 311 is the same, which is clockwise.

[0056] The axes of the first rollers 311 intersect at the same point, the first rollers 311 are tilted and the inclination angle of the first rollers 311 is equal to the inclination angle of the first conveying surface; the conveying surface of the first conveying roller device 31 is the arc-shaped conveying surface, and the inlet end of the first conveying roller device 31 is connected with the outlet end of the first conveying surface. Since the first rollers 311 are evenly distributed within a range of 180° around the same axis, the directions of the inlet end and the outlet end of the arc-shaped conveying surface formed by them are flipped by 180°.

[0057] The structure of the second conveyor mesh belt device 32 is the same as that of the first conveyor mesh belt device, except that the conveying direction is opposite, and it will not be repeated here. Of course, the upper and lower ends of the second conveyor mesh belt device 32 are also provided with angle supports 8, which play the same supporting role. The angle supports 8 are arranged throughout the length, and the cross section of the angle supports 8 is a right angle. The mesh belt of the first conveyor mesh belt can be slidably mounted on the angle supports 8; the front and rear end surfaces of the angle supports 8 are fixedly connected to the housing 1.

[0058] The inlet end of the second conveying mesh belt device 32 is connected to the outlet end of the first conveying roller device 31 , and the conveying surface of the second conveying mesh belt device 32 is the second conveying surface.

[0059] In order to prevent the tableware from sliding from the inclined arc-shaped conveying surface and the second conveying surface during conveying and being unable to be conveyed, the cleaning conveying mechanism 3 also includes a second conveying roller device 33 and a third conveying roller device 34 for limiting the tableware from sliding down.

[0060] The second conveying roller device 33 includes a plurality of vertically arranged second roller shafts 311 and a second roller shaft 311 driving device for driving the second roller shafts 311 to rotate, and of course, a supporting frame for mounting each second roller shaft 311 and a transmission gear between two adjacent second roller shafts 311. The second roller shaft 311 driving device can use a roller shaft motor and replace one of the second roller shafts 311.

[0061] The second rollers 311 are evenly spaced along the lower edge of the first conveying roller device 31, and the lower ends of the second rollers 311 are close to the lower ends of the first rollers 311 to prevent the tableware from sliding out of the arc-shaped conveying surface. At the same time, the rotation of the second rollers 311 can also help the conveying of the tableware, which can also be understood as the first conveying roller device 31 and the second conveying roller device 33 clamping the tableware and moving it. From a top view, the second conveying roller device 33 is a semicircular arc and is coaxial with the semicircular table of the first conveying roller device 31.

[0062] The third conveying roller device 34 includes a plurality of vertically arranged third roller shafts 341 and a third roller shaft 341 driving device for driving the third roller shafts 341 to rotate, and of course, a supporting frame for mounting each third roller shaft 341 and a transmission gear between two adjacent third roller shafts 341. The third roller shaft 341 driving device can use a roller shaft motor and replace one of the third roller shafts 341.

[0063] The third rollers 341 are evenly spaced along the lower edge of the second conveying mesh belt device 32, and the lower end of the second roller 311 is close to the lower end of the second conveying surface to prevent the tableware from sliding out of the second conveying surface. At the same time, the rotation of the third roller 341 can also help the tableware to be conveyed, which can also be understood as the third conveying roller device 34 and the second conveying mesh belt device 32 clamping the tableware and moving it. From a top view, the third conveying roller devices 34 are arranged in a line.

[0064] In order to improve the cleaning efficiency of tableware, the first roller 311 and / or the second roller 311 is a brush roller, which brushes the tableware while conveying it. At the same time, the impact force of the water column can also press the tableware against the conveying surface, thereby enhancing the cleaning effect of the brush on the roller, separating the food residue on the tableware from the tableware as soon as possible, and improving the cleaning effect.

[0065] The sprayers are divided into two groups, one group is arranged outside the first conveying roller device 31 and the second conveying mesh belt device 32, and the other group is arranged outside the second conveying roller device 33 and the third conveying roller device 34. The two groups of sprayers spray the tableware with high pressure from both sides of the tableware at the same time, thereby improving the cleaning efficiency and cleaning effect.

[0066] Preferably, the sprayers are divided into a first hot water sprayer 41, a cold water sprayer 42 and a second hot water sprayer 43 along the conveying direction of the cleaning conveying mechanism 3; the spraying temperature of the first hot water sprayer 41 is 60-70°C, the area where the first hot water sprayer 41 is set is long, and it accounts for about 70% of the entire cleaning mechanism, so as to perform preliminary comprehensive cleaning; the spraying temperature of the cold water sprayer 42 is 20-30°C, and the area of ​​the cold water sprayer 42 accounts for about 20% of the entire conveying and cleaning mechanism. The tableware is washed with hot water and then with cold water. With the cold contraction and thermal expansion effect of cold water, the stains attached to the tableware can be effectively removed; the water inlet of the second hot water sprayer 43 is connected to a heat pump hot water device (not shown in the figure), the water inlet pipe of the heat pump hot water device is directly connected to the tap water pipe, and the heat pump hot water device can quickly heat the tap water to a higher temperature. The area of ​​the second hot water sprayer 43 accounts for about 10% of the entire conveying and cleaning mechanism, and finally a higher temperature cleaning is performed to ensure cleaning.

[0067] Among them, the heat pump water heater includes a PTC heater and a heat pump water heater. The heat pump water heater adopts an existing heat pump water heater, which includes an evaporator, a compressor, an expansion valve and a condenser. Since it is a prior art, its structure is not described here. The fan of the evaporator is provided with an exhaust pipe connected to the housing 1 of the tableware cleaning device to extract the heat in the tableware cleaning device for recycling and reduce energy consumption. Since the maximum heating temperature of the existing heat pump water heater is about 60°C, it cannot reach the temperature required by the device. Therefore, the outlet pipe of the heat pump water heater is connected to the PTC heater, and the water passing through is further heated by the PTC heater to make the water temperature reach 80-90°C.

[0068] The pumping mechanism includes a first pump body 44 connected to the first hot water shower 41 and a second pump body 45 connected to the cold water shower 42 .

[0069] Wherein, the first hot water sprayer 41 is a box-type sprayer, such as Figure 8 As shown, it includes a box-type body 411 with an inner cavity and a water inlet joint 412 connected to the inner cavity, the box-type body 411 is provided with a plurality of spray holes 413, and the water inlet joint 412 is connected to the first pump body 44 through a pipeline. The box-type sprayer can generate high-pressure and dense spray water columns, and the spray cleaning effect is better than that of ordinary sprayers or spray arms.

[0070] The cold water sprayer 42 and the second hot water sprayer 43 may be common sprayers or box-type sprayers.

[0071] Preferably, a hot water recovery container 5 and a cold water recovery container 6 are provided below the cleaning and conveying mechanism 3; Figure 5As shown, the water inlet pipes of the first pump body 44 and the second pump body 45 are respectively inserted into the hot water recovery container 5 and the cold water recovery container 6. The hot water recovery container 5 and the cold water recovery container 6 are used to recycle the water sprayed from the first hot water sprayer 41, the cold water sprayer 42 and the second hot water sprayer 43 to reduce energy consumption and water consumption.

[0072] The edge of the upper opening of the hot water recovery container 5 is provided with an inclined collecting guide plate 51, and the collecting guide plate 51 extends to the lower part of the entire cleaning conveying mechanism 3. The collecting guide plate 51 can collect the water sprayed by the first hot water sprayer 41 and the second hot water sprayer 43 into the hot water recovery container 5. The hot water recovery container 5 is also connected to a hot water input pipe, which inputs new hot water from the outside into the hot water recovery container 5 to replenish hot water.

[0073] A collector 61 is provided below the cold water sprayer 42 , and the collector 61 may be a funnel. The collector 61 is provided with a conduit passing through the collecting guide plate 51 and communicating with the cold water recovery container 6 . The collector 61 can collect the water sprayed by the cold water sprayer 42 into the cold water recovery container 6 .

[0074] The drain outlet of the evaporator of the heat pump water heater is connected to the cold water recovery container 6, and the condensed water of the evaporator is discharged into the cold water recovery container 6 to replenish cold water.

[0075] As a preference, the device further comprises a start sensor 7 disposed at the tableware recovery port 11. Figure 6 The start sensor 7 is electrically connected to the control device. The start sensor 7 can be a grating sensor. When sensing that the customer puts in tableware, the recovery conveying mechanism 2, the cleaning conveying mechanism 3, and the spraying device 4 of the tableware cleaning device are started to convey and spray. If there is no subsequent input after completing a cycle, the conveying and spraying are stopped and the device enters a standby state to reduce energy consumption.

[0076] For other contents of the turning type tableware cleaning device described in the present invention, please refer to the prior art and will not be described in detail here.

[0077] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
