Description

Technical Field

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

[0002] A dishwasher is a device that sprays cold or hot water onto dishes to remove dirt adhering to the dishes and clean the dishes. When in use, the dishes are placed in the bowl basket of the sink dishwasher. The sink dishwasher includes a washing pump that sprays washing water, a spray arm, and a heater that produces hot water. The washing pump sprays washing water into the bowl basket of the sink dishwasher to clean the dishes.

[0003] Existing sink dishwashers generally have one or two sprayers, which spray from bottom to top or both. The position of the spray hole determines that there are inevitably places on the tableware that cannot be sprayed, or even if some places are sprayed, it is not conducive to cleaning the tableware due to the small impact. Among them, although the dynamic spray arm with a nozzle can reduce the number of dead corners, the position of the static spray nozzle is fixed, resulting in more dead corners in the sink dishwasher. The dirt in the dead corners cannot be cleaned. Static spray only solves the above problems through a single or multiple spray ports. The spray port has a small coverage area and cannot achieve the effect of water mist combination. The separate steam generating port cannot cooperate with the back static spray, occupies the inner tank space, and the cost is relatively high.

[0004] A Chinese patent application with application number CN 201410470042.1 discloses a cleaning machine, comprising a container with an inner cavity, a water outlet pipe being provided below the container, an openable and closable water inlet hole being provided on the bottom surface or the peripheral surface of the container, a water inlet pipe being provided on the outer side of the container and being movably inserted into or extended from the water inlet hole, a foldable bowl basket separated from the inner cavity being placed in the inner cavity, the foldable bowl basket comprising a bowl basket frame and a rotating spray arm and a water supply pipe which are foldable with each other, a plurality of oblique upward nozzles being provided on the surface of the rotating spray arm facing the bowl basket frame; the water supply pipe being detachably connected to the water inlet pipe, the top of the container having an upward opening, the opening being provided with a lid which can be opened or closed relative to the container.

[0005] Although the above-mentioned prior art has solved certain technical problems, there are still problems that static spray only solves the above problems through a single or multiple nozzles, the nozzle has a small coverage area, and the effect of water mist combination cannot be achieved. The separate steam generating port cannot cooperate with the back static spray, occupies the inner tank space, and the cost is relatively high. The dynamic spray has problems in washing dead corners during washing and cleaning and disinfecting tableware (second shelf) in the area covered by the tableware.

[0006] Therefore, it is necessary to improve the shortcomings and defects of the existing technology, and provide a combination of dynamic and static spraying to cover the dead corners of washing and improve the washing effect; solve the problem of washing dishes on the second shelf; set a booster port to increase the coverage area of ​​the spray port, increase the spray pressure, shorten the washing time, and turn water into a combination of water mist to achieve the functions of flushing and soaking; set a steam generating port to spray steam from the multiple steam ports at the bottom, so as to achieve a sink dishwasher spray structure 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 sink dishwasher spray structure 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 structure of a sink dishwasher, including a dynamic spray arm arranged at the bottom of the sink dishwasher body and capable of rotatably spraying; at least one static spray arm arranged on the side wall of the sink dishwasher body and capable of static directionally spraying; at least one group of first spray units is provided on the dynamic spray arm, and at least one group of second spray units is provided on the static spray arm; the static spray arm has a built-in booster port and a steam generating port.

[0010] Furthermore, the distance from the boost port to the bottom of the tank body is greater than the distance from the second spray unit to the bottom of the tank body.

[0011] Among them, a boosting plate is arranged on the boosting port, and the boosting plate increases the pressure of the water flow passing through, and changes the water flow into a form combined with water mist; a boosting port is arranged in the static spray to increase the coverage area of ​​the injection port, increase the injection pressure, and shorten the washing time; a steam generating port is arranged to spray steam from the multiple steam ports at the bottom, which plays the role of soaking and disinfection.

[0012] In addition, the distance from the steam generating port to the bottom of the tank body is smaller than the distance from the second spray unit to the bottom of the tank body.

[0013] At the same time, the second spray unit includes a first spray hole, a second spray hole and a third spray hole; the spray angles of the first spray hole, the second spray hole and the third spray hole do not interfere with each other, and 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.

[0014] In one embodiment, the spray injection pipeline in the second spray unit forms a first washing chamber.

[0015] In one embodiment, the boost injection pipeline in the boost port forms a second washing chamber.

[0016] In one embodiment, the steam injection pipeline in the steam generating port forms a steam chamber.

[0017] Furthermore, the first washing chamber, the second washing chamber and the steam chamber are independent of each other, and the chambers are independent of each other to ensure sufficient water pressure.

[0018] In addition, the spray path formed by the spray injection pipeline, the boost injection pipeline and the steam injection pipeline of the second spray unit is toward the bottom of the sink dishwasher. When the water level in the sink is too high or splashes, water will flow out from the pipeline inclined toward the bottom of the sink.

[0019] In one embodiment, the first spray unit, the second spray unit and the pressure boosting port are connected to the water inlet pipe through a connecting pipe.

[0020] In one embodiment, the steam generating port is connected to the steam generator through a connecting pipe.

[0021] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0022] 1. The combination of dynamic and static spraying covers the dead corners of washing, improves the washing effect, and solves the cleaning problem of the area where the second layer of tableware is covered by the first layer of tableware;

[0023] 2. By setting the booster port, the coverage area of ​​the jet port is increased, the jet pressure is increased, the washing time is shortened, and the water pressure at the local position is increased;

[0024] 3. By setting a boost port, water is transformed into a combination of water and mist to achieve the functions of flushing and soaking;

[0025] 4. By connecting the steam generator, steam is sprayed from multiple steam ports at the bottom to achieve the purpose of soaking and disinfection;

[0026] 5. The first washing chamber, the second washing chamber and the steam chamber are independent of each other to ensure sufficient water pressure.

[0027] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] 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.

[0037] 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.

[0038] 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.

[0039] like Figures 1 to 4As shown, a spray structure of a sink dishwasher of the present invention comprises a dynamic spray arm 3 which is arranged at the bottom of a sink body 2 of the sink dishwasher 1 and can rotatably spray; at least one static spray arm 4 which is arranged at the side wall of the sink body 2 of the sink dishwasher 1 and can statically and directionally spray; at least one group of first spray units 5 are arranged on the dynamic spray arm 3, and the rotation of the dynamic spray arm 3 is achieved by generating a reverse driving force during the spraying process of at least one group of first spray units 5, and at least one group of second spray units 6 are arranged on the static spray arm 4; the static spray arm 4 has a built-in boost port 7 and a steam Generating port 8; the distance from the boost port 7 to the bottom of the trough body 2 is greater than the distance from the second spray unit 6 to the bottom of the trough body 2. This arrangement allows high-pressure water mist to be above the spray water flow, so that the coverage area of ​​the spray port is larger, the spray pressure is increased, the washing time is shortened, and the water is converted into a form of water mist combination to achieve the functions of flushing and soaking; the distance from the steam generating port 8 to the bottom of the trough body 2 is less than the distance from the second spray unit 6 to the bottom of the trough body 2. This arrangement allows steam to be ejected from the multiple steam ports at the bottom, achieving better soaking and disinfection effects.

[0040] Among them, the second spray unit 6 includes a first spray hole 601, a second spray hole 602 and a third spray hole 603; the spray angles of the first spray hole 601, the second spray hole 602 and the third spray hole 603 do not interfere with each other. In the existing sink dishwasher 1 solution, static spray only solves the above problems through a single or multiple spray ports, and the spray port has a small coverage range and cannot achieve the effect of water mist combination. The separate steam generating port 8 cannot cooperate with the back static spray, occupies the inner tank space, and the cost is relatively high. The sink dishwasher 1 described in the present application further includes a dish rack (not marked in the drawings), and the dish rack (not marked in the drawings) is a dish rack with at least two layers (not marked in the drawings). The multi-angle spray cleaning of the spray structure allows the washing process to cover the washing dead corners, improve the washing effect, and solve the problem of washing dishes on the second shelf.

[0041] The spray injection pipeline in the second spray unit 6 forms a first washing chamber 9; the boost injection pipeline in the boost port 7 forms a second washing chamber 10; the steam injection pipeline in the steam generating port 8 forms a steam chamber 11; the first washing chamber 9, the second washing chamber 10 and the steam chamber 11 are independent chambers.

[0042] At the same time, a boosting plate 15 is provided on the boosting port 7, and the boosting plate 15 increases the pressure of the water flow passing through, and changes the water flow into a form combined with water mist; a boosting mechanism is provided in the static spray to increase the coverage area of ​​the injection port, increase the injection pressure, and shorten the washing time; a steam generator (not shown in the accompanying drawings) is connected to spray steam from the multiple steam ports at the bottom to achieve the effect of soaking and disinfection.

[0043] Furthermore, the first washing chamber 9, the second washing chamber 10 and the steam chamber 11 are independent chambers, and the chambers are all independent of each other to ensure sufficient water pressure.

[0044] In addition, the spraying spray pipeline, the boosting spray pipeline and the steam spray pipeline of the second spray unit 6 form a spray path toward the bottom of the tank body 2 of the sink dishwasher 1. When the water level in the sink is too high or splashes, water will flow out from the pipeline inclined toward the bottom of the tank body 2.

[0045] The working range of the second spray unit 6 is larger than the working range of any one of the boost port 7 and the steam generating port 8, so as to prevent tableware and fruits and vegetables from being damaged by high-pressure spray and steam in the absence of water.

[0046] The present invention combines a static spray structure on the side of a sink dishwasher 1 with a dynamic spray structure arranged at the bottom of the sink, integrating multi-angle spraying, flushing and soaking combined with water mist, soaking and disinfection functions of hot steam, and an overflow port function of the sink, mainly solving the problem of washing and disinfecting tableware (second-layer shelf) in dead corners and areas covered by tableware during washing by dynamic spraying, increasing the washing area and the coverage of the spray port, thereby ensuring the cleaning and disinfection effect of the sink dishwasher 1.
