Description

Technical Field

[0001] The invention belongs to the field of dishwashers, and in particular relates to a spray system of a sink dishwasher. Background Art

[0002] A sink dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. It can be divided into two categories according to its structure: box-type and conveyor-type. Conveyor-type sink dishwashers are mainly used in large catering places such as restaurants, hotels, and canteens of government agencies, thereby reducing the labor intensity of cooks, improving work efficiency, and improving cleanliness and hygiene. Other box-type sink dishwashers are mainly used in home kitchens. Some home sink dishwashers are also combined with sinks for washing dishes and vegetables. How to remove excess water in the sink has become an urgent problem to be solved.

[0003] A Chinese patent application with application number CN201210157913.5 discloses a washing machine, comprising a container with an inner cavity, a water outlet pipe connected to the inner cavity of the container is arranged below the container, the container comprises a bottom surface and a peripheral surface around the bottom surface, a water inlet pipe is arranged on the bottom surface or the peripheral surface of the container, the inner cavity has a space for placing a bowl basket for placing dishes to be washed, the bowl basket and the container are separate parts, a plurality of spaced spray heads are arranged on at least a portion of the inner surface of the container toward the container, the spray heads 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 arranged on the opening.

[0004] The Chinese patent application number CN201620688519.8 discloses an overflow device for a sink dishwasher, which is designed to solve the technical problem that the existing similar products have poor structural design and are difficult to use in sink-type sink dishwashers. The overflow device includes an overflow head, an overflow seat, an overflow cover and an outlet pipe, the outlet pipe is connected to one side of the overflow head through an outlet member, and the box body is a stainless steel sink; the key points are that the other side of the overflow head is provided with an inlet member, that is, the inlet pipe is connected to the other side of the overflow head through the inlet member, the inlet member is connected to the overflow seat, and a sealing ring is provided at the connection; the upper port of the inlet member is provided with a spray port smaller than the inlet port, and a rectangular annular overflow cavity is also provided below the spray port of the inlet member; a water inlet flow meter is provided between the inlet member and the inlet pipe, and a water inlet valve switch is provided at the inlet of the inlet pipe, and the water inlet flow meter is connected to the control panel of the box body through a line.

[0005] However, the above two overflow structures are directly connected to the overflow pipe through the 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 and increasing the cleaning cost. At the same time, there is also the problem that the static spray only solves the above problems through a single or multiple nozzles. The nozzle has a small coverage area and cannot achieve the effect of water mist combination. The separate steam unit cannot cooperate with the back static spray, occupies the inner tank space, and the cost is relatively high. There are problems with washing and disinfecting the tableware (second shelf) in the dead corners of washing and the area covered by the tableware during washing.

[0006] Therefore, it is necessary to improve the shortcomings and defects of the prior art and provide a method of reserving an overflow port on the side spray structure so that when an abnormal water level appears in the sink dishwasher, water can be discharged from the inner tank of the machine in time, while reducing components and reducing costs; multi-angle spray cleaning allows the washing process to cover dead corners, improve the washing effect, and solve the problem of washing dishes on the second shelf. At the same time, a booster unit is set to increase the coverage area of ​​the spray port, increase the spray pressure, shorten the washing time, and turn water into a form of water mist to achieve the functions of flushing and soaking; a steam unit is set to spray steam from multiple steam ports at the bottom to achieve a spray system with soaking and disinfection functions.

[0007] In view of this, the present invention is 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 spray system for a sink dishwasher that can overcome the above problems or at least partially solve the above problems.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a spray system for a sink dishwasher, including a static spray arm, which is arranged on the side wall of the sink body of the sink dishwasher; the static spray arm is also provided with a booster unit for spraying high-pressure water mist, a steam unit for spraying high-temperature steam and an overflow port; the side wall of the sink body is provided with an installation groove matching the shape of the static spray arm.

[0010] Among them, the static spray arm is provided with a first water inlet pipe, a second water inlet pipe, a steam pipe and a drain pipe on one side close to the side wall of the tank body, so as to meet the functions of spraying, misting, steaming and overflowing in the spraying system.

[0011] In addition, the mounting groove of the side wall of the groove body is provided with openings through which the first water inlet pipe, the second water inlet pipe, the steam pipe and the drain pipe pass.

[0012] At the same time, it includes a gasket that matches the shape of the installation slot opening. The gasket is installed on the side of the static spray arm close to the side wall of the slot body. The setting of the static spray arm gasket effectively alleviates the overall vibration when the static spray arm is working, avoiding structural damage.

[0013] In addition, the static spray arm includes at least one group of spray units that spray spray water.

[0014] Furthermore, the spray unit includes at least two spray holes, each spray hole sprays in a different direction, and multi-angle spray cleaning avoids the existence of cleaning dead corners, improves the washing effect, and solves the problem of cleaning tableware on the second shelf.

[0015] In one embodiment, the working range of the spray unit is larger than the working range of the boost unit and the steam unit, so as to prevent tableware and fruits and vegetables from being damaged by high-pressure spray and / or steam in the absence of water.

[0016] In one embodiment, the boost unit is provided with a boost turbine, and the boost turbine is arranged inside the static spray arm.

[0017] In one embodiment, steam units are provided on both sides of the boosting unit.

[0018] In one embodiment, the distances from the spray unit, booster unit, steam unit and overflow port to the bottom of the trough body decrease successively, and the distances from the spray, mist and steam to the bottom of the trough body decrease successively, and the structural design of low water level overflow makes the entire spray washing process more three-dimensional.

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

[0020] 1. Multi-angle spray cleaning allows the washing process to cover dead corners, improve the washing effect, and solve the cleaning problem of the area where the second layer of tableware is covered by the first layer of tableware;

[0021] 2. By setting up a booster unit, the coverage area of ​​the jet nozzle is increased, the jet pressure is increased, the washing time is shortened, and the water pressure at the local position is increased;

[0022] 3. By setting up a booster unit, water is transformed into a combination of water and mist to achieve the functions of flushing and soaking;

[0023] 4. By connecting the steam generator, steam is sprayed from multiple steam ports at the bottom to achieve the purpose of soaking and disinfection;

[0024] 5. The static spray arm is equipped with an isolation part, which isolates any combination of the spray unit, booster unit, steam unit and overflow port into independent chambers. The independent setting between the chambers ensures sufficient water pressure;

[0025] 6. 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 time, which can reduce the number of parts and reduce costs.

[0026] 7. The setting of the static spray arm gasket can effectively alleviate the overall vibration when the static spray arm is working, avoiding structural damage.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0041] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0042] 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.

[0043] like Figures 1 to 8As shown, a spray system of a sink dishwasher of the present invention comprises a dynamic spray arm 4, which is rotatably arranged at the bottom 2 of the sink body of the sink dishwasher 1; a static spray arm 5, which is arranged at the side wall 3 of the sink body of the sink dishwasher 1; the static spray arm 5 is also provided with a booster unit 6 for spraying high-pressure water mist, a steam unit 7 for spraying high-temperature steam, and an overflow port 8. Furthermore, the sink dishwasher 1 of the present invention also comprises a dish rack, which is a dish rack structure of at least two layers, and the dynamic spray arm 4 is provided with a corresponding washing water spray unit 6 for spraying high-pressure water mist, a steam unit 7 for spraying high-temperature steam, and an overflow port 8. The water sprayed from the spray hole generates reverse power to drive the dynamic spray arm 4 to rotate, so as to achieve a comprehensive washing effect for the tableware on the bottom layer (first shelf) of the dish rack; the static spray arm 5 includes at least one group of spray units 9, and the spray unit 9 includes at least two spray holes 10, each spray hole 10 sprays in a different direction, and multi-angle spray cleaning solves the problem of cleaning and disinfecting tableware (second shelf) in cleaning dead corners and areas covered by tableware, improves the washing effect, and solves the problem of cleaning tableware on the second shelf.

[0044] The static spray arm 5 also includes a booster turbine 11 corresponding to the booster unit 6. The booster turbine 11 is arranged inside the static spray arm 5. Steam units 7 are arranged on both sides of the booster unit 6. The high-pressure spray makes the tableware and fruits and vegetables clean more thoroughly under the action of steam. The high-pressure water mist mainly cleans 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 damage to the surface of the tableware and fruits and vegetables is also avoided.

[0045] The boost turbine 11 is composed of several boost plates with different internal angles. Due to the different setting angles of the boost plates, the flow direction and flow basin of the passing water are changed and then intersected, which increases the water flow pressure and changes the water flow into a form combined with water mist.

[0046] In addition, the overflow port 8 is a long hole structure, and at least one of the overflow ports 8 is arranged on the side of the static spray arm 5 close to the bottom of the sink. The setting of the long hole reduces the impact of the water flow on the static spray arm 5 and also increases the water flow basin, so that excess water in the sink can pass better.

[0047] like Figure 1 to Figure 2 As shown, a spray system of a sink dishwasher includes a first solenoid valve 26, wherein the first solenoid valve 26 controls water flow through the first solenoid valve 26, a respirator 28, and a water softener 29 and then flows into a water storage unit 30; the water storage unit 30 is provided with a first water inlet pipe 21 and a third water inlet pipe 23, wherein the first water inlet pipe 21 is connected to a static spray arm 5 arranged on a side wall 3 of the tank body, and the third water inlet pipe 23 is connected to a dynamic spray arm 4 arranged on a bottom 2 of the tank body; and further includes a second solenoid valve 27, wherein the second solenoid valve 27 controls water flow through the second solenoid valve 27 and then enters the static spray arm 5 through the second water inlet pipe 22.

[0048] like Figures 3 to 5 As shown, the trough side wall 3 is provided with a mounting groove 31 matching the shape of the static spray arm 5; the mounting groove 31 of the trough side wall 3 is provided with an opening 32 through which the first water inlet pipe 21, the second water inlet pipe 22, the steam pipe 24 and the drain pipe 25 pass.

[0049] At the same time, it includes a gasket 33 that matches the shape of the opening 32 of the mounting groove 31. The gasket 33 is installed on the side of the static spray arm 5 close to the side wall 3 of the tank body. The gasket 33 is supported by a vibration-damping material. When the static spray arm 5 is working, the static spray arm 5 will vibrate due to the spraying and high-pressure spraying. Long-term operation will cause damage to the static spray arm 5 and even the side wall of the entire dishwasher. At the same time, since the static spray arm 5 is made of plastic material, it will be deformed under the action of high temperature of steam. Therefore, the setting of the gasket 33 effectively alleviates the overall vibration when the static spray arm 5 is working, avoiding damage to the structure. At the same time, a gap is set between the static spray arm 5 and the mounting groove 31 of the sink dishwasher 1, and a deformation space of the static spray arm 5 due to the action of high temperature of steam is reserved. The mounting groove 31 and the gasket 33 are both provided with corresponding mounting holes, so that the static spray arm 5 is fixed in the mounting groove 31 by bolts.

[0050] like Figure 6 As shown, the distances from the spray unit 9, the booster unit 6, the steam unit 7 and the overflow port 8 to the bottom 2 of the tank body decrease successively, and the distances of the spray, the mist and the steam from the bottom 2 of the tank body decrease successively, and the structural design of 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 of the spray unit 9, the booster unit 6 and the steam unit 7, the steam unit 7 is closer to the bottom 2 of the tank body. In order to avoid damage to the surface of tableware and fruits and vegetables during the cleaning process, the working range of the spray needs to be larger than the working range of the high-pressure spray and the steam, so the spray unit 9 is set at a position higher than the position of the booster unit 6.

[0051] like Figures 7 and 8 As shown, the static spray arm 5 includes a spray front part 501 and a spray rear part 502; the spray front part 501 and the spray rear part 502 are fixedly connected to form the static spray arm 5; the spray front part 501 and the spray rear part 502 are made of plastic; the spray front part 501 and the spray rear part 502 are connected by hot melting to form a sealed cavity, and the hot melting connection into an integrated structure makes the sealing effect of the static spray arm 5 better, and the installation is convenient and the structure is simple.

[0052] In addition, the static spray arm 5 is also provided with an isolation part 12, which includes a first isolation unit 1201 and a second isolation unit 1202. The first isolation unit 1201 and the second isolation unit 1202 divide the inner sides of the spray front part 501 and the spray rear part 502 into a spray chamber 13, a booster chamber 14, a steam chamber 15 and an overflow chamber 16. The multi-chamber setting makes the static spray arm 5 have a clear functional division and a clear structure.

[0053] Furthermore, when the spray front part 501 and the spray rear part 502 are connected into one by hot-melt connection, the first isolation unit 1201 is connected to the second isolation unit 1202 correspondingly, and the spray chamber 13, the boost chamber 14, the steam chamber 15 and the overflow chamber 16 are divided into independent chambers. The setting of the independent chambers ensures that the functional chambers do not interfere with each other under the premise of ensuring the realization of their functions.

[0054] At the same time, the spray rear portion 502 is respectively provided with a first water inlet hole 17, a second water inlet hole 18, a steam hole 19 and an overflow hole 20 corresponding to the spray chamber 13, the boost chamber 14, the steam chamber 15 and the overflow chamber 16.

[0055] The static spray arm 5 is provided with a first water inlet pipe 21, a second water inlet pipe 22, a steam pipe 24 and a drain pipe 25 on one side close to the tank side wall 3, so as to meet the functions of spraying, misting, steaming and overflowing in the spray system.

[0056] Furthermore, the first water inlet hole 17, the second water inlet hole 18, the steam hole 19 and the overflow hole 20 are respectively connected to the first water inlet pipe 21, the second water inlet pipe 22, the steam pipe 24 and the drain pipe 25 provided at the rear part 502 of the spray.

[0057] In general, the spray system of the sink dishwasher 1 of the present invention adopts multi-angle spray cleaning so that the washing process can cover the dead corners of washing, improve the washing effect, solve the cleaning work of the area where the second layer of tableware is covered by the first layer of tableware, and by setting the booster unit 6, the coverage area of ​​the spray port is increased, the spray pressure is increased, and the washing time is shortened. Through the structure, the water pressure at the local position is increased. By setting the booster unit 6, the water is changed into a form of water mist, and the functions of flushing and soaking are realized. By connecting the steam generator, steam is sprayed from the multiple steam ports at the bottom. , which plays the role of soaking and disinfecting. The static spray arm 5 is provided with an isolation part 12, which isolates the spray unit 9, the booster unit 6, the steam unit 7 and the overflow port 8 into independent chambers in any combination. The independent setting between the cavities ensures sufficient water pressure. The overflow port 8 is reserved on the side spray structure. When an abnormal water level appears in the sink dishwasher 1, the water can be discharged from the inner tank of the machine in time, and the parts can be reduced to reduce the cost. At the same time, the setting of the gasket 33 of the static spray arm 5 effectively alleviates the overall vibration when the static spray arm 5 is working, thereby avoiding damage to the structure.

[0058] Embodiment 1

[0059] like Figures 1 to 8 As shown, a spray system of a sink dishwasher of the present invention comprises a dynamic spray arm 4, which is rotatably arranged at the bottom 2 of the sink body of the sink dishwasher 1; a static spray arm 5, which is arranged at the side wall 3 of the sink body of the sink dishwasher 1; the static spray arm 5 is also provided with a booster unit 6 for spraying high-pressure water mist, a steam unit 7 for spraying high-temperature steam, and an overflow port 8. Further, the sink dishwasher 1 of the present invention also comprises a dish rack, which is a dish rack structure of at least two layers, and corresponding washing water spray holes are arranged on the dynamic spray arm 4. The water sprayed from the spray hole generates reverse power, driving the dynamic spray arm 4 to rotate, so as to achieve a comprehensive washing effect of the tableware on the bottom layer of the dish rack; the static spray arm 5 comprises at least one group of spray units 9, and the spray unit 9 comprises at least two spray holes 10, and each spray hole 10 sprays in a different direction. The multi-angle spray cleaning solves the problem of cleaning and disinfecting the tableware (second-layer rack) in the cleaning dead corner and the area covered by the tableware, improves the washing effect, and solves the problem of cleaning the tableware on the second-layer rack.

[0060] The static spray arm 5 also includes a booster turbine 11 corresponding to the booster unit 6. The booster turbine 11 is arranged inside the static spray arm 5. Steam units 7 are arranged on both sides of the booster unit 6. The high-pressure spray makes the tableware and fruits and vegetables clean more thoroughly under the action of steam. The high-pressure water mist mainly cleans 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 damage to the surface of the tableware and fruits and vegetables is also avoided.

[0061] The boost turbine 11 is composed of several boost plates with different angles. Due to the different setting angles of the boost plates, the flow direction and flow basin of the passing water are changed and then intersected, which increases the water flow pressure and changes the water flow into a form combined with water mist.

[0062] In addition, the overflow port 8 is a long hole structure, and at least one of the overflow ports 8 is arranged on the side of the static spray arm 5 close to the bottom of the sink. The setting of the long hole reduces the impact of the water flow on the static spray arm 5 and also increases the water flow basin, so that excess water in the sink can pass better.

[0063] Embodiment 2

[0067] At the same time, it includes a gasket 33 that matches the shape of the opening 32 of the installation groove 31. The gasket 33 is installed on the side of the static spray arm 5 close to the side wall 3 of the tank body. The gasket 33 is supported by a vibration-damping material. When the static spray arm 5 is working, the static spray arm 5 will vibrate due to the spraying and high-pressure spraying. Long-term operation will cause damage to the static spray arm 5 and even the side wall of the entire dishwasher. At the same time, since the static spray arm 5 is made of plastic material, it will be deformed under the action of high temperature of steam. Therefore, the setting of the gasket 33 effectively alleviates the overall vibration when the static spray arm 5 is working, avoiding damage to the structure. At the same time, a gap is set between the static spray arm 5 and the installation groove 31 of the sink dishwasher 1, reserving deformation space for the static spray arm 5 due to the action of high temperature of steam.

The structural design of 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 of the spray unit 9, the booster unit 6 and the steam unit 7, the steam unit 7 is closer to the bottom 2 of the tank body. In order to avoid damage to the surface of tableware and fruits and vegetables during the cleaning process, the working range of the spray needs to be larger than the working range of the high-pressure spray and the steam. Therefore, the spray unit 9 is set at a position higher than the position of the booster unit 6.

[0094] The present embodiment is different from the above-mentioned embodiment thirteen in that, in the static spray arm 5 described in the present embodiment, the spray unit 9, the booster unit 6, and the steam unit 7 are at the same height from the bottom of the tank body of the sink dishwasher.

[0095] Embodiment 15

[0096] This embodiment is a further limitation of the above-mentioned embodiment 1. In the static spray arm 5 described in this embodiment, the distances from the spray unit 9, the steam unit 7, the boosting unit 6 and the overflow port 8 to the bottom 2 of the tank body decrease successively. The sequential decrease in the distances of the spray, the mist and the steam from the bottom 2 of the tank body and the design of low water level overflow make the entire spray washing process more three-dimensional. Since the specific gravity of steam is less than that of water, in the arrangement of the spray unit 9, the boosting unit 6 and the steam unit 7, the steam unit 7 is closer to the bottom 2 of the tank body. In order to avoid damage to the surface of tableware and fruits and vegetables during the cleaning process, the working range of the spray needs to be larger than the working range of the high-pressure spray and the steam. Therefore, the spray unit 9 is set at a position higher than the boosting unit 6.
