Description

Technical Field

[0001] The present invention belongs to the field of dishwashers, and more particularly, relates to a sink dishwasher. Background Art

[0002] A sink dishwasher is a device for automatically cleaning tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. It can be classified into two major categories according to its structure: box type and conveyor type. Among them, the conveyor type sink dishwasher is mainly used in large catering places such as restaurants, hotels, and canteens of government agencies, so as to reduce the labor intensity of cooking staff, improve work efficiency, and improve cleaning and sanitation.

[0003] Chinese Patent with application number CN 201210157913.5 discloses a cleaning machine, which includes a container with an inner cavity. A water outlet pipe is provided below the container and is connected to the inner cavity of the container. The container includes a bottom surface and a peripheral surface located around the bottom surface. A water inlet pipe is provided on the bottom surface or the peripheral surface of the container. There is a space in the inner cavity for placing a bowl basket for holding tableware to be washed. The bowl basket and the container are separate parts. At least a part of the inner surface of the container is provided with a plurality of spaced nozzles facing into the container. The nozzles are connected to the water inlet pipe. The top of the container has an upward opening, and a lid that can be opened or closed relative to the container is provided on the opening.

[0004] Chinese Patent with application number CN 201710089158.4 discloses a respirator with a condensation drying function, which includes a box body and a lid body that are buckled together. The box body is provided with a steam inlet connected to the inner cavity of the dishwasher and a steam outlet connected to the outside. The box body is provided with a water separation port and a drain port. A water storage cavity is formed between the water separation port and the drain port in the box body. A condensation channel is provided between the steam inlet and the steam outlet in the box body. The condensation channel is arranged in the water storage cavity. A condensation water discharge port is provided below the condensation channel, and a fan is provided at the end of the condensation channel.

[0005] Respirators and blowers are essential components of dishwashers. Currently, in the prior art, the respirator and the blower air duct are mostly installed as single components, with a complex structure and time-consuming installation. Although the above two types of respirators have solved certain existing problems, in the prior art, the connection between the blower and the air duct is a rigid connection, and the vibration generated during the operation of the blower will be transmitted through this connection and then amplified. At the same time, during the operation of the dishwasher, the overflow pipe is directly connected through an opening, which may cause the water splashed into the opening during the cleaning process to flow out directly through the overflow pipe, resulting in unnecessary loss of cleaning water, affecting the cleaning effect, increasing the cleaning cost. At the same time, there is also the problem that static spraying only solves the above problems through single or multiple spray nozzles, with a small coverage area of the spray nozzles and unable to achieve the effect of water mist combination. A separate steam unit cannot cooperate with the rear static spraying, occupying the inner tank space and having a relatively high cost. There are also problems with the cleaning and disinfection of tableware in the washing dead corners and the areas covered by tableware (the second shelf) during washing.

[0006] Therefore, it is necessary to improve the deficiencies and defects of the prior art and provide an integrated respirator and air duct structure with high integration and easy installation. At the same time, the connection between the blower and the air duct uses a rubber flexible connection, avoiding the rigid connection between the blower and the air duct, and preventing the vibration generated during the operation of the blower from being transmitted and amplified through this connection, which may cause damage to the respirator and the dishwasher. At the same time, an overflow port is reserved on the side spray structure. When the water level in the sink dishwasher is abnormal, the water can be discharged from the inner tank of the machine in a timely manner, while reducing components and costs. Multi-angle spray cleaning enables the washing process to cover the washing dead corners, improving the washing effect and solving the problem of cleaning the tableware on the second shelf. At the same time, a pressurizing unit is set to increase the coverage area of the spray nozzles, increase the spray pressure, shorten the washing time, turn the water into a water mist combination form, and achieve the functions of flushing and soaking. A steam unit is set to spray steam from multiple steam outlets at the bottom, serving as a sink dishwasher with the functions of soaking and disinfection.

[0007] In view of this, the present invention is specifically proposed. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a sink dishwasher that can overcome or at least partially solve the above problems.

[0009] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a sink dishwasher, including a respirator base connected to the outer side of the side wall of the tank body, a respirator housing used in cooperation with the respirator base; a ventilation unit, including an air duct air inlet provided on the respirator base and an air duct connected to the air duct air inlet; a static spray arm, with at least one provided on the side wall of the tank body.

[0010] Among them, the ventilation unit further includes a switching valve plate disposed in the air duct. The switching valve plate unidirectionally conducts the air duct and the inner liner of the dishwasher. The setting of the switching valve plate can ensure that during the washing process, it is in a closed state due to gravity, and the overflow of water and gas during the washing process can be avoided.

[0011] Meanwhile, the ventilation unit further includes a blower and a fixing member for fixing the blower. A damping unit is provided on the contact surface between the fixing member and the blower to fixedly connect the blower and the respirator. Since the blower and the air duct are rigidly connected, the vibration generated during the operation of the blower will be transmitted and amplified through this connection, causing damage to the respirator.

[0012] In addition, the fixing member includes a first hanging member, and the first hanging member cooperates with a second hanging member disposed on the outer shell of the respirator to fix the blower, which is simple to install and has high integration.

[0013] Moreover, a fixing bracket for fixing the drain pipe is provided on the base of the respirator to fix the drain pipe outside the inner liner of the dishwasher, making the structure more compact and reasonable.

[0014] In addition, a strip-shaped air inlet is provided on the side of the base of the respirator communicating with the inner liner of the dishwasher. This strip-shaped air port communicates with the exhaust port of the respirator in the washing cavity, ensuring the air pressure balance in the inner liner of the dishwasher when the dishwasher lid is closed.

[0015] Furthermore, the static spray arm includes a pressurizing unit for spraying high-pressure water mist, a steam unit for spraying high-temperature steam, and an overflow port, making the cleaning process more thorough under the action of high-pressure spraying and high-temperature steam. At the same time, the setting of the overflow port ensures the safety of the water level in the inner liner of the dishwasher.

[0016] Even further, the static spray arm includes at least one set of spray units for spraying spray water. The spray unit includes at least two spray holes, and the spraying directions of each spray hole are different. The multi-angle spraying and cleaning avoid the existence of cleaning dead corners, improve the washing effect, and solve the problem of cleaning tableware on the second shelf.

[0017] In one embodiment, the working range of the spray unit is larger than that of any one of the pressurizing unit and the steam unit, preventing tableware and fruits and vegetables from being damaged by high-pressure spraying and steam in the case of no water.

[0018] In one embodiment, the distances from the spray unit, the pressurizing unit, the steam unit, and the overflow port to the bottom of the tank decrease in sequence. The structural design of the distances from spraying, spraying mist, and steam to the bottom of the tank decreasing in sequence and the low water level overflow make the entire spray washing process more three-dimensional.

[0019] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art:

[0020] 1. The respirator and the ventilation unit are designed as an integrated unit, making the overall integration performance higher and easier to install.

[0021] 2. A switching valve plate is provided, which can ensure that it is in a closed state due to gravity during the washing process, avoiding the overflow of water and gas during the washing process.

[0022] 3. A vibration damping unit is provided between the fan and the fixing part, avoiding the vibration generated during the operation of the fan being transmitted and amplified through this connection, causing damage to the respirator.

[0023] 4. The fan and the respirator are connected by a hanging part, which is convenient to install and more practical while ensuring the function.

[0024] 5. A strip-shaped air inlet is provided, which is communicated with the exhaust port of the respirator in the washing cavity, ensuring the air pressure balance in the inner tank of the dishwasher.

[0025] 6. Multi-angle spray cleaning enables the washing process to cover the washing dead corners, improving the washing effect and solving the cleaning work in the area covered by the first layer of tableware for the second layer of tableware.

[0026] 7. By setting a pressurizing unit, the water is turned into a form combined with water mist, realizing the functions of scouring and soaking, increasing the coverage area of the spray port, increasing the spray pressure, shortening the washing time, and increasing the water pressure at local positions.

[0027] 8. An overflow port is reserved on the side spray structure. When there is an abnormal water level in the sink dishwasher, the water can be discharged from the inner tank of the machine in time while reducing components and costs.

[0028] The following further describes in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Description of the Drawings

Detailed implementation manners

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying 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.

[0039] In the description of the present invention, it should be noted that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0040] 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 directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Such as Figures 1 to 5As shown in the figure, the present invention includes a respirator base 3 connected to the outside of the side wall 1 of the tank body, a respirator housing 2 used in cooperation with the respirator base 3. Further, it also includes a respirator fixing unit 23 and an exhaust port fixing unit 24 provided on the side wall 1 of the tank body; a ventilation unit 4, including an air duct inlet 5 provided on the respirator base 3 and an air duct 6 connected to the air duct inlet 5; a static spray arm 16, with at least one provided on the side wall 1 of the tank body.

[0042] As Figure 4 shown, one side of the respirator port and the air duct inlet 5 is connected to the inside of the washing cavity, and the other side is an integrated cavity formed by the respirator and the air duct 6. This integrated cavity is divided into two parts. The respirator cavity is in the middle, and the air duct 6 cavity is around; the respirator base 3 of the present invention is also provided with a water inlet 25 and a water outlet 26. The area formed by the water inlet 25 and the water outlet 26 is a water flow channel 27. The respirator also includes a flow meter 22, which calculates the amount of water passing through the respirator and sends a signal to the control center when the starting water volume is reached. Further, the area formed by the air duct 6 and the fan 9 of the present invention is an air flow channel 28.

[0043] The ventilation unit 4 further includes a switching valve plate 7 provided in the air duct 6. The switching valve plate 7 unidirectionally conducts the air duct 6 and the dishwasher inner tank 8. The setting of the switching valve plate 7 can ensure that during the washing process, it is in a closed state due to gravity, and the overflow of water and gas during the washing process can be avoided.

[0044] In addition, the ventilation unit 4 further includes a fan 9 and a fixing member 10 for fixing the fan 9, which fixedly connects the fan 9 and the respirator.

[0045] At the same time, a vibration damping unit 11 is provided on the contact surface between the fixing member 10 and the fan 9. Since the fan 9 and the air duct 6 are rigidly connected, the vibration generated during the operation of the fan 9 will be transmitted through this connection and then amplified, causing damage to the respirator.

[0046] And, the fixing member 10 includes a first hanging member 12, and the first hanging member 12 cooperates with a second hanging member 13 provided on the respirator housing 2 to fix the fan 9, with simple installation and high integration.

[0047] In addition, the respirator base 3 is provided with a fixing bracket 14 for fixing the drain pipe, which fixes the drain pipe outside the dishwasher inner tank 8, making the structure more compact and reasonable.

[0048] Further, a strip-shaped air inlet 15 is provided on the side of the respirator base 3 communicating with the dishwasher inner tank 8. This strip-shaped air port communicates with the respirator exhaust port in the washing cavity, ensuring the air pressure balance of the dishwasher inner tank 8 when the dishwasher lid is closed.

[0049] Further, the static spray arm 16 includes a pressurizing unit 17 for spraying high-pressure water mist, a steam unit 18 for spraying high-temperature steam, and an overflow port 19, making the cleaning process more thorough under the action of high-pressure spraying and high-temperature steam. At the same time, the setting of the overflow port 19 ensures the safety of the water level in the inner tank 8 of the dishwasher.

[0050] Furthermore, the static spray arm 16 includes at least one set of spray units 20 for spraying spray water. The spray unit 20 includes at least two spray holes 21, and the spraying directions of each spray hole 21 are different. The multi-angle spraying cleaning avoids the existence of cleaning dead corners, improves the washing effect, and solves the problem of cleaning the tableware on the second shelf.

[0051] The static spray arm 16 further includes a supercharging turbine corresponding to the pressurizing unit 17. The supercharging turbine is arranged inside the static spray arm 16, and steam units 18 are provided on both sides of the pressurizing unit 17. The high-pressure spraying makes the cleaning of tableware and fruits and vegetables more thorough under the action of steam. The high-pressure water mist mainly plays a role in cleaning the stubborn stains and pesticides remaining on the tableware and fruits and vegetables. Under the action of steam, the effect of the high-pressure water mist is more obvious, and it also avoids damage to the surfaces of tableware and fruits and vegetables.

[0052] The supercharging turbine is composed of a number of supercharging vanes with different angles inside. Due to the different setting angles of the supercharging vanes, the flow direction and flow domain of the passing water flow change and then intersect, increasing the water flow pressure and turning the water flow into a form combined with water mist.

[0053] In addition, the overflow port 19 has a long strip hole structure, and at least one overflow port 19 is arranged on the side of the static spray arm 16 close to the bottom of the sink. The setting of the long strip holes reduces the impact of the water flow on the static spray arm 16 and also enlarges the flow domain of the water flow, making the excessive water in the sink more permeable.

[0054] Generally speaking, the present invention provides an integrated respirator and air duct 6 structure with high integration and easy installation. At the same time, the connection between the fan 9 and the air duct 6 adopts a rubber flexible connection, avoiding the hard connection between the fan 9 and the air duct 6. The vibration generated by the operation of the fan 9 will be transmitted through this connection and then amplified, causing damage to the respirator and the dishwasher. At the same time, an overflow port 19 is reserved on the side spray structure. When the water level in the sink dishwasher is abnormal, the water can be discharged from the inner tank of the machine in time, and at the same time, the number of components can be reduced and the cost can be lowered; the multi-angle spraying cleaning enables the washing process to cover the washing dead corners, improves the washing effect, and solves the problem of cleaning the tableware on the second shelf. At the same time, a pressurizing unit 17 is set to increase the coverage area of the spraying port, increase the spraying pressure, shorten the washing time, turn the water into a form combined with water mist, and realize the functions of flushing and soaking; a steam unit 18 is set to spray steam from multiple steam outlets at the lower part, serving as a dishwashing device with the functions of soaking and disinfection.

[0055] Embodiment 1

[0056] As Figures 1 to 5 shown, the respirator of the sink dishwasher in this embodiment includes a respirator base 3 connected to the outside of the side wall 1 of the tank body, and a respirator housing 2 used in cooperation with the respirator base 3. Further, it also includes a respirator fixing unit 23 and an exhaust port fixing unit 24 provided on the side wall 1 of the tank body; a ventilation unit 4, which includes an air duct air inlet 5 provided on the respirator base 3 and an air duct 6 connected to the air duct air inlet 5.

[0057] As Figure 4 shown, one side of the respirator port and the air duct air inlet 5 is connected to the inside of the washing cavity, and the other side is an integrated cavity formed by the respirator and the air duct 6. This integrated cavity is divided into two parts. The respirator cavity is in the middle, and the air duct 6 cavity is around; the respirator base 3 of the present invention is also provided with a water inlet 25 and a water outlet 26. The area formed by the water inlet 25 and the water outlet 26 is a water flow channel 27. The respirator also includes a flow meter 22, which calculates the amount of water passing through the respirator and sends a signal to the control center when the starting water volume is reached. Further, the area formed by the air duct 6 and the fan 9 of the present invention is an air flow channel 28.

[0058] The ventilation unit 4 also includes a switching valve piece 7 provided in the air duct 6. The switching valve piece 7 conducts the air duct 6 and the dishwasher inner tank 8 unidirectionally. The setting of the switching valve piece 7 can ensure that during the washing process, it is in a closed state due to gravity, and the overflow of water and gas during the washing process can be avoided.

[0059] In addition, the ventilation unit 4 also includes a fan 9 and a fixing member 10 for fixing the fan 9, which fixedly connects the fan 9 to the respirator.

[0060] At the same time, a vibration damping unit 11 is provided on the contact surface between the fixing member 10 and the fan 9. Since the fan 9 and the air duct 6 are rigidly connected, the vibration generated during the operation of the fan 9 will be transmitted and amplified through this connection, causing damage to the respirator.

[0061] Moreover, the fixing member 10 includes a first hanging member 12, and the first hanging member 12 cooperates with a second hanging member 13 provided on the respirator housing 2 to fix the fan 9, which is simple to install and has high integration.

[0062] In addition, the respirator base 3 is provided with a fixing bracket 14 for fixing the drain pipe, which fixes the drain pipe to the outside of the dishwasher inner tank 8, making the structure more compact and reasonable.

[0063] Furthermore, a strip-shaped air inlet 15 is provided on the side of the respirator base 3 communicating with the inner liner 8 of the dishwasher. This strip-shaped air port communicates with the respirator exhaust port in the washing cavity, ensuring the air pressure balance in the inner liner 8 of the dishwasher.

[0064] Embodiment 2

[0065] As Figures 1 to 5 shown, this embodiment is a further limitation of the above Embodiment 1. In this embodiment, the damping unit 11 is made of rubber material.

[0066] Embodiment 3

[0067] As Figures 1 to 5 shown, this embodiment is a further limitation of the above Embodiment 1 or 2. The sink dishwasher in this embodiment includes a static spray arm 16, which is arranged on the side wall 1 of the tank body. The static spray arm 16 includes a pressurizing unit 17 for spraying high-pressure water mist, a steam unit 18 for spraying high-temperature steam, and an overflow port 19, making the cleaning process more thorough under the action of high-pressure spraying and high-temperature steam. At the same time, the setting of the overflow port 19 ensures the safety of the water level in the inner liner 8 of the dishwasher.

[0068] Furthermore, the static spray arm 16 includes at least one set of spray units 20 for spraying spray water. The spray unit 20 includes at least two spray holes 21, and the spraying directions of each spray hole 21 are different. Spraying and cleaning from multiple angles avoid the existence of cleaning dead corners, improve the washing effect, and solve the problem of cleaning tableware on the second shelf.

[0069] The static spray arm 16 also includes a supercharging turbine corresponding to the pressurizing unit 17. The supercharging turbine is arranged inside the static spray arm 16. Steam units 18 are provided on both sides of the pressurizing unit 17. High-pressure spraying makes the cleaning of tableware and fruits and vegetables more thorough under the action of steam. The high-pressure water mist mainly plays a role in cleaning stubborn stains and pesticides remaining on tableware and fruits and vegetables. Under the action of steam, the effect of the high-pressure water mist is more obvious, and it also avoids damage to the surfaces of tableware and fruits and vegetables.

[0070] The supercharging turbine is composed of several supercharging vanes with different angles inside. Due to the different setting angles of the supercharging vanes, the flow direction and flow domain of the passing water flow change and then intersect, increasing the water flow pressure and turning the water flow into a form combined with water mist.

[0071] In addition, the overflow port 19 is of a long strip hole type structure. At least one overflow port 19 is arranged on the side of the static spray arm 16 close to the bottom of the sink. The setting of the long strip holes reduces the impact of the water flow on the static spray arm 16 and also increases the flow domain of the water flow, making the excessive water in the sink more permeable.

[0072] Embodiment 4

[0073] AsFigures 1 to 5 As shown, this embodiment is a further limitation of the above-mentioned Embodiment 3. In this embodiment, the distances from the spray unit 20, the pressurizing unit 17, the steam unit 18, and the overflow port 19 to the bottom of the tank decrease in sequence. The structural design of the spray, atomization, and steam with decreasing distances from the bottom of the tank and the low-water-level overflow makes the entire spray washing process more three-dimensional. Since the specific gravity of steam is less than that of water, in the arrangement order of the spray unit 20, the pressurizing unit 17, and the steam unit 18, the steam unit 18 is closer to the bottom of the tank. And in order to avoid damage to the surfaces of tableware and fruits and vegetables during the cleaning process, the working range of spraying needs to be larger than that of high-pressure atomization and steam. Therefore, the spray unit 20 is arranged at a position higher than the pressurizing unit 17.

[0074] Embodiment 5

[0075] As Figures 1 to 5 shown, this embodiment is a further limitation of the above-mentioned Embodiment 3 or 4. At least two static spray arms 16 of this embodiment are arranged on the side wall 1 of the tank.

[0076] Embodiment 6

[0077] This embodiment is a further limitation of any one of the above-mentioned Embodiments 1 to 5. The outer side of the cavity of the respirator in this embodiment is a duct 6 cavity. The duct 6 cavity is a U-shaped cavity with an air inlet at one end. The air inlet is connected to the inside of the washing cavity, and the other end is connected to the fan 9 through a fixing member 10 provided with a damping unit 11.

[0078] Embodiment 7

[0079] This embodiment is a further limitation of any one of the above-mentioned Embodiments 1 to 5. The outer side of the cavity of the respirator in this embodiment is a duct 6 cavity. The duct 6 cavity is an L-shaped cavity with an air inlet at one end. The air inlet is connected to the inside of the washing cavity, and the other end is connected to the fan 9 through a fixing member 10 provided with a damping unit 11.
