[0048] The present invention mainly proposes a spray module, which is mainly used in dishwashers. The nozzle 310 rotates to spray, which greatly reduces the volume of the water spray structure, so that the nozzle 310 is not easily stuck by foreign objects during the water spraying process, which is beneficial to improving the working stability of the water spray module 300; at the same time, the nozzle 310 rotates to spray water, so that each nozzle 310 can radiate a larger cleaning range. When multiple nozzles 310 are arranged in the dishwasher inner tank 100, water can be sprayed to every angle of the inner tank 100, so that the tableware can be fully rinsed, which is beneficial to improving the coverage of the nozzle 310 rinsing area.

[0049] The specific structure of the spray washing module will be mainly described below.

[0050] Reference Figures 1 to 8In an embodiment of the present invention, the spray washing module includes:

[0051] A nozzle 310, wherein 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;

[0052] A bracket 320, wherein a mounting position for mounting the nozzle 310 is provided on the bracket 320, and the nozzle 310 is rotatably connected to the bracket 320;

[0053] The driving mechanism 330 is connected to the nozzle 310 to drive the nozzle 310 to rotate relative to the bracket 320 .

[0054] Specifically, in this embodiment, the shape of the nozzle 310 can be various. For example, the columnar setting is used 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 extends along the length direction of the nozzle 310. There can be many forms of the bracket 320 and the mounting position, and the forms of the bracket 320 and the mounting position are not specifically limited here. For example, the mounting column 322, the mounting cavity, etc., as long as it can support and limit the nozzle 310 and allow the nozzle 310 to rotate. There can also be various forms of the driving structure, such as direct drive by a motor, or indirect drive through a transmission mechanism. Of course, in some embodiments, it can also be driven by water energy through an impeller 350. There can be various forms of water supply to the nozzle 310, such as supplying water to the nozzle 310 through a water pump so that water is sprayed from the water outlet 311 under the action of water pressure.

[0055] 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 sprayed out from the water outlet 311 through the flow channel 312. Under the rotation of the nozzle 310, the water sprayed from the water outlet 311 forms a water supply area. When the water outlet 311 has an angle, different angles correspond to different water supply areas. By setting water outlets 311 with different angles, the coverage ranges of different nozzles 310 are different. Since 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 required position in the dishwasher inner tank 100 as needed, which greatly improves the installation adaptability of the water spray structure. At the same time, the shape of the inner tank 100 can be arbitrarily improved as needed (not limited by the shape of the water spray structure, the nozzle 310 can meet the spraying and washing needs of the entire inner tank 100), providing support for the shape diversification of the inner tank 100.

[0056] It is worth mentioning that, by the rotation of the nozzle 310 itself for spraying, the volume of the water spraying structure is greatly reduced, so that the nozzle 310 is not easily stuck by foreign objects during the water spraying process, which is beneficial to improving the working stability of the water spraying module 300; at the same time, by the rotation of the nozzle 310 for spraying water, each nozzle 310 can radiate a larger cleaning range. When multiple nozzles 310 are arranged in the dishwasher inner tank 100, water can be sprayed to every angle of the inner tank 100, so that the tableware can be fully rinsed, which is beneficial to improving the coverage of the nozzle 310 rinsing area.

[0057] The driving structure is introduced below. In order to improve the driving stability and transmission accuracy, the driving mechanism 330 includes: a driving gear 331; a driven gear, the driven gear is connected to the nozzle 310, and the driven gear is meshed with the driving gear 331; and a power source, the power source drives the driving gear 331 to rotate.

[0058] The power source drives the driving gear 331 to rotate along its rotation axis, and the driven gear rotates under the drive of the driving gear 331, and the driven gear drives the nozzle 310 to rotate. There are many ways to connect the driven gear and the nozzle 310, such as fixed connection, detachable connection, etc. Take the driven gear being sleeved on the side wall of the nozzle 310 and fixedly connected to the driven gear as an example. An installation space is provided in the middle of the driven gear, and the driven gear is sleeved on the nozzle 310 which is arranged in a columnar shape, so that the nozzle 310 rotates with the rotation of the driven gear. Among them, the rotation axis of the driven gear is arranged in parallel with the rotation axis of the nozzle 310, and it is preferred that the two are colinear. By driving the nozzle 310 by the driving gear 331 and the driven gear, the rotation angle of the nozzle 310 can be precisely controlled, which is conducive to improving the precision and accuracy of the water spraying of the nozzle 310.

[0059] 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.

[0060] When there are multiple nozzles 310, the number of the driven gears is equal to the number of the nozzles 310; and the driven gears are meshed with the driving gear 331 at the same time. At this time, one driving gear 331 can drive multiple driven gears at the same time, that is, drive multiple nozzles 310, so that one power source can drive multiple nozzles 310 at the same time, thereby greatly improving the driving efficiency of the power source. Among them, the number of nozzles 310 and driven gears is taken as three for example, that is, one driving gear 331 drives three driven gears and nozzles 310 at the same time, so that while ensuring the driving efficiency of the power source, it can also ensure that the power source has sufficient driving capacity.

[0061] Regarding the power source, the power source includes a driving impeller 350, and the driving impeller 350 is coaxially arranged with the driving gear 331. The driving impeller 350 rotates under the action of water flow or motor, taking water flow as an example. 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.

[0062] In some embodiments, in order to obtain a spraying area that is compatible with the dishwasher model, an angle is set between the water outlet direction of the water spray port and the length direction of the flow channel 312, so that the water sprayed from the water outlet 311 has a spray angle that is compatible with the actual use situation, so that the water can be sprayed to the required position in the inner tank 100. The angle α between the direction of the water outlet 311 and the horizontal direction is 40° to 65°, with 45° and 60° as examples. By setting the angle α to 40° to 65°, the water supply pressure of the water pump corresponds to the spraying area covered by each nozzle 310 and the actual working condition of the nozzle 310, avoiding the situation where the spraying is not clean when the angle is too large, and the area covered by each nozzle 310 is too small when the angle is too small. It is worth noting that when there are multiple nozzles 310, the angle α between the direction of the water outlet of the nozzle 310 and the horizontal direction can be different, that is, one of them can be 45°, the other can be 60°, etc., which greatly improves the flexibility of the setting of the nozzle 310, makes the spray module suitable for dishwashers in more working conditions, and greatly improves the adaptability of the spray module.

[0063] In order to allow the nozzle 310 to stably rotate on the bracket 320, the bracket 320 includes a mounting post 322, and the nozzle 310 includes a mounting portion, which is sleeved on the mounting post 322 and rotates with the mounting post 322 as a rotation axis. The mounting portion has a mounting cavity corresponding to the mounting post 322, and the mounting portion can be located in many positions, for example, it can be set on the side of the nozzle 310, isolated from the flow channel 312 of the nozzle 310; it can also be set to communicate with the flow channel 312, and even the mounting cavity and the flow channel 312 overlap. By sleeved on the mounting post 322, the nozzle 310 rotates with the mounting post 322 as a rotation axis, so that the rotation of the nozzle 310 is stable and reliable.

[0064] In order to reasonably utilize the space and improve the compactness and stability of the structure, a water passage 323 is provided on the mounting column 322 along its axial direction; the mounting portion is the flow channel 312, the mounting column 322 is inserted into the flow channel 312, and the water passage 323 is in communication with the flow channel 312. 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 is in communication with the flow channel 312, and the installation (rotating shaft) of the nozzle 310 and the water supply are organically combined, the space of the nozzle 310 is fully and reasonably utilized, and the space required for installing the nozzle 310 is greatly reduced, making the installation and use of the nozzle 310 more flexible.

[0065] In order to improve the rotation stability of the nozzle 310, the bracket 320 includes a mounting box 321, the mounting column 322 is arranged at the bottom of the mounting box 321, and a through hole 324 connected to the water passage 323 is provided at the bottom of the mounting box 321; and a through hole 325 is provided at the top of the mounting box 321 for the water sprayed by the nozzle 310 to pass through. By arranging the mounting column 322 in the mounting box 321, since the nozzle 310 is sleeved on the mounting column 322, the driven gear located 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 position of 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.). The through hole 324 can be located in multiple positions, for example, it can be directly opened at the bottom of the mounting column 322, so that the water passage 323 is directly connected to the through hole 324; it can also be opened at other positions at the bottom, and an opening connecting the inside of the mounting box 321 and the water passage 323 is opened on the side wall of the mounting column 322. In this case, the through hole 324 is connected to the water passage 323 through the opening and the internal space of the mounting box 321. The top of the nozzle 310 can be located in the mounting box 321, or it can extend out of the mounting box 321 through the through opening 325. The water outlet 311 of the nozzle 310 is connected to the through opening 325. For example, the water outlet 311 of the nozzle 310 is located outside the mounting box 321 to avoid the top of the mounting box 321 blocking the water spray.

[0066] In some embodiments, in order to simplify the manufacturing and assembly process of the mounting column 322, the mounting column 322 is integrally formed with the bottom of the mounting box 321, and the through hole 324 is coaxially arranged with the water passage 323. The through hole 324 is located at the bottom of the mounting column 322, and the water passage 323 is directly connected to the outside of the mounting box 321 through the through hole 324. By coaxially arranging the through hole 324 and the water passage 323, the external water can directly enter the water passage 323 without turning, thereby avoiding the loss of water energy and at the same time, avoiding the formation of turbulent flows such as eddies.

[0067] The present invention also provides a dishwasher, which includes an inner tank 100 and a spray module. The specific structure of the spray module refers to the above embodiment. Since the present dishwasher adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The inner tank 100 has a receiving cavity 110; the spray module is arranged in the receiving cavity 110.

[0068] In order to ensure the washing effect of the dishwasher, the number of the spray modules is multiple, and the multiple spray modules are distributed at the bottom of the receiving chamber 110; the dishwasher includes a water inlet pipe 210 and multiple water distribution pipes 220, one end of the water distribution pipe 220 is connected to the water inlet pipe 210, and the other end is connected to the spray module. The number of spray modules can be many, such as three, five, seven, etc., and the specific number can be set according to the shape and size of the inner tank 100, with the premise of ensuring the cleaning effect. By distributing multiple spray modules at the bottom of the receiving chamber 110 and configuring the water distribution pipes 220 to communicate with them, the working condition of each spray module can be controlled separately according to the actual situation. For example, only three of the five cleaning modules are turned on, or the spray conditions of three of them are different from the spray conditions of the remaining two, etc. It is worth noting that the deflection angle α of the nozzle 310 in different spray modules can be different and can be set according to actual needs.

[0069] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
