This application mainly proposes a spray washing module, which is mainly used in dishwashers. The nozzle 310 itself rotates and sprays, which greatly reduces the volume of the water spray structure, so that the nozzle 310 is not easily caught by foreign objects during the water spraying process. , Which is conducive to improving the working stability of the water spray module 300; at the same time, the nozzle 310 rotates the water spray, so that each nozzle 310 can radiate a larger cleaning range, when multiple nozzles are arranged in the dishwasher liner 100 At 310, water can be sprayed to every angle of the liner 100, so that the dishes can be fully washed, which is beneficial to increase the coverage of the nozzle 310 washing area.

The specific structure of the spray washing module will be mainly described below.

1 to 8, in the embodiment of the present application, the spray washing module includes:

A nozzle 310, the nozzle 310 has a water inlet 313, a water outlet 311, and a flow channel 312 connecting the water inlet 313 and the water outlet 311;

A bracket 320, the bracket 320 is provided with an installation position for installing the nozzle 310, and the nozzle 310 is rotatably connected with the bracket 320;

The driving mechanism 330 is connected to the nozzle 310 to drive the nozzle 310 to rotate relative to the bracket 320.

Specifically, in this embodiment, the shape of the nozzle 310 may be various. Taking a cylindrical shape as an example, the water inlet 313 is located at one end of the nozzle 310, the water outlet 311 is located at the other end of the nozzle 310, and the flow channel 312 is along the nozzle 310. Lengthwise. There may be many forms of the bracket 320 and the mounting position, and the form of the bracket 320 and the mounting position is not specifically limited here, such as the mounting post 322, the mounting cavity, etc., as long as the nozzle 310 can support and limit the nozzle 310, and can rotate the nozzle 310 The structure can be. There may also be many types of driving structures, such as direct driving by a motor or indirect driving by a transmission mechanism. Of course, in some embodiments, the impeller 350 may also be driven by hydraulic energy. Regarding the water supply of the nozzle 310, there may be various forms, for example, water is supplied to the nozzle 310 by a water pump, so that water is sprayed from the water outlet 311 under the action of water pressure.

In this embodiment, under the driving action of the driving mechanism 330 and the support of the bracket 320, the nozzle 310 rotates, and the water entering the water inlet 313 of the nozzle 310 is ejected from the water outlet 311 through the flow channel 312, and the rotation of the nozzle 310 The water sprayed from the water outlet 311 forms a water delivery area. When the water outlet 311 has a declination angle, different declination angles correspond to different water delivery areas. By setting the water outlet 311 with different declination angles, different nozzles 310 are covered The range is different; because the volume of the nozzle 310 is very small, the space requirement of the nozzle 310 for the installation position is greatly reduced, so that the nozzle 310 can be arranged at any desired position in the dishwasher liner 100 according to the need, which greatly improves The installation adaptability of the water spray structure also makes the shape of the liner 100 can be arbitrarily improved according to the needs (not limited by the shape of the water spray structure, the nozzle 310 can meet the spraying needs of the full liner 100), which is the liner The shape of 100 provides support.

It is worth noting that the rotating spray of the nozzle 310 itself greatly reduces the volume of the water spray structure, so that the nozzle 310 is not easily caught by foreign objects during the water spray process, which is beneficial to improve the working stability of the water spray module 300; At the same time, the water is sprayed through the nozzles 310 so that each nozzle 310 can radiate a larger cleaning range. When multiple nozzles 310 are arranged in the dishwasher tank 100, water can be sprayed to each of the tank 100 The angle, so that the dishes can be sufficiently washed, is beneficial to improve the coverage of the nozzle 310 washing area.

The drive structure is described below. In order to improve the stability of the drive and the accuracy of the transmission, the drive mechanism 330 includes: a driving gear 331; a driven gear, the driven gear is connected to the nozzle 310, and the driven gear is The driving gear 331 meshes; a power source that drives the driving gear 331 to rotate.

The power source drives the driving gear 331 to rotate along its rotation axis, the driven gear rotates under the driving of the driving gear 331, and the driven gear drives the nozzle 310 to rotate. There are many ways to connect the driven gear to the nozzle 310, such as fixed connection, detachable connection and so on. For example, the driven gear is sleeved on the side wall of the nozzle 310 and fixedly connected to the driven gear. An installation space is provided in the middle of the driven gear, and the driven gear is sleeved on the nozzle 310 provided in a column shape, so that the nozzle 310 rotates with the rotation of the driven gear. Among them, the rotation axis of the driven gear and the rotation axis of the nozzle 310 are arranged in parallel, and it is preferable that the two are collinear. The driving gear 331 and the driven gear drive the nozzle 310, so that the rotation angle of the nozzle 310 can be accurately controlled, which is beneficial to improve the accuracy and accuracy of the nozzle 310 spraying water.

In some embodiments, in order to simplify the processing and assembly process of the nozzle 310 and the driven gear, the driven gear and the nozzle 310 are integrally formed.

When the number of the nozzles 310 is plural, the number of the driven gears is equivalent to the number of the nozzles 310; how many of the driven gears simultaneously mesh with the driving gear 331. At this time, one driving gear 331 can simultaneously drive multiple driven gears, that is, multiple nozzles 310, so that one power source can drive multiple nozzles 310 at the same time, so as to greatly improve the driving efficiency of the power source. Among them, the number of the nozzle 310 and the driven gear is three as an example, that is, one driving gear 331 drives three driven gears and the nozzle 310 at the same time. In this way, while ensuring the driving efficiency of the power source, it can also ensure that the power source has Enough capacity to drive.

Regarding the power source, the power source includes a driving impeller 350 that is coaxially disposed with the driving gear 331. The driving impeller 350 rotates under the action of the water flow or the motor, taking the example of being driven by the water flow. After the rotating shaft of the driving impeller 350 is inserted into the shaft hole at the center of the driving gear 331, the driving impeller 350 and the driving gear 331 share the same rotating shaft, so that the driving gear 331 rotates with the rotation of the impeller 350.

In some embodiments, in order to obtain a spray area suitable for the dishwasher model, an angle is set between the water outlet direction of the water outlet and the length direction of the flow channel 312, so that the water sprayed from the water outlet 311 The water has a spray angle adapted to the actual use situation, so that the water can be sprayed to the desired position in the liner 100. The angle α between the direction of the water outlet 311 and the horizontal direction is 40 ° to 65 °, taking 45 ° and 60 ° as examples. By setting the angle α to 40 ° ~ 65 °, the water supply pressure of the water pump corresponds to the spraying area covered by each nozzle 310 and the actual working conditions of the nozzle 310, to avoid the spray cleaning when the angle is too large, If the angle is too small, the area covered by each nozzle 310 is too small. It is worth noting that when the number of the nozzles 310 is multiple, the angle α between the orientation of the nozzles of the nozzles 310 and the horizontal direction may be different, that is, one of them may be 45 °, the other may be 60 °, etc., so that The flexibility of setting the nozzle 310 is greatly improved, so that the spray washing module can be applied to dishwashers in more working conditions, and the adaptability of the spray washing module is greatly improved.

In this embodiment, the flow channel 312 is directly sleeved on the mounting column 322, so that the water passage 323 on the mounting column 322 communicates with the flow channel 312, which organically combines the installation (rotation shaft) of the nozzle 310 and the water supply, fully The space of the nozzle 310 is reasonably utilized, and the space required for installing the nozzle 310 is greatly reduced, so that the installation and use of the nozzle 310 are more flexible.

In order to improve the stability of the rotation of the nozzle 310, the bracket 320 includes a mounting box 321, and the mounting post 322 is disposed at the bottom of the mounting box 321. The bottom of the mounting box 321 is provided with a communication with the water passage 323 Via hole 324; the top of the mounting box 321 is provided with a port 325 through which the water sprayed from the nozzle 310 passes. By installing the mounting post 322 in the mounting box 321, since the nozzle 310 is sleeved on the mounting post 322, the driven gear at the bottom of the nozzle 310 is also located in the mounting box 321, and the meshing position of the driving gear 331 and the driven gear is also Located in the mounting box 321. The meshing part between the driving gear 331 and the driven gear is protected by the mounting box 321 to avoid the influence of external environmental factors (such as dust, debris, etc.). There may be multiple positions of the via hole 324, for example, it is directly opened at the bottom of the mounting post 322, so that the water passage 323 is directly communicated with the via hole 324; There is an opening connecting the inside of the mounting box 321 and the water passage 323. At this time, the via hole 324 communicates with the water passage 323 through the opening and the internal space of the mounting box 321. The top of the nozzle 310 may be located in the mounting box 321, or may extend out of the mounting box 321 through the port 325. The water outlet 311 of the nozzle 310 communicates with the port 325. Taking the water outlet 311 of the nozzle 310 located outside the mounting box 321 as an example, the top of the mounting box 321 prevents the spray of water from being blocked.
