For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0024] First, a conventional drum washing machine will be described.

[0025] During the use of the existing drum washing machine, since the water inlet pipe of the washing machine is set on the outer drum, during the rinsing and water injection stage, the injected water needs to first enter the gap between the outer drum and the inner drum. As the amount of water injected increases, the injected water gradually fills the gap between the outer drum and the inner drum, and then can overflow into the inner drum and soak the clothes to be rinsed. In this process, since the water in the gap between the outer drum and the inner drum has no effect on rinsing, it will not improve the rinsing effect, and it also causes a waste of water resources, prolongs the water injection time, reduces the rinsing efficiency, and brings a bad user experience. In order to change this situation, the following technical solution is proposed, which is introduced below using a drum washing machine as an example.

[0026] like Figure 1 , Figure 2As shown, in order to solve the problem that the existing washing equipment adopts the form of flooding during the rinsing water filling process, water needs to first fill the gap between the outer drum and the inner barrel, resulting in a waste of water resources, the drum washing machine of the utility model includes a water inlet pipe 2, the water outlet of the water inlet pipe 2 is arranged on the window pad 1 of the washing equipment, and a nozzle 3 is arranged at the water outlet of the water inlet pipe 2. The nozzle 3 is L-shaped, and the first end of the L-shaped nozzle 3 is detachably connected to the water outlet of the water inlet pipe 2, and the second end faces the direction of the inner drum of the washing equipment. The cross-section of the second end of the nozzle 3 is semicircular, and the water flowing out of the water inlet pipe 2 can be sprayed into the inner drum of the washing equipment through the nozzle 3.

[0027] When the above-mentioned embodiment is adopted, during the use of the washing device of the utility model, in the rinsing and water injection stage, the water flow can directly flow along the water inlet pipe 2 to the nozzle 3 of the water outlet fixed on the window pad 1. Since the nozzle 3 is L-shaped, and the first end of the L-shaped nozzle 3 is detachably connected to the water outlet of the water inlet pipe 2, and the other end is facing the direction of the inner drum of the washing device, the water flow can be sprayed from the second end of the nozzle 3 into the inner drum of the washing device, and directly sprayed on the clothes to be rinsed to rinse the clothes, thereby avoiding the problem of wasting water resources in the prior art that water needs to first enter the gap between the outer drum and the inner drum during the rinsing and water injection stage, and then overflow from the gap between the outer drum and the inner drum to the inside of the inner drum and the clothes in the inner drum.

[0028] In addition, regarding the shape of the nozzle 3, it can be understood by those skilled in the art that, although it is mentioned above that the nozzle 3 is L-shaped, this is not the only embodiment. Those skilled in the art can also set the nozzle 3 to other common shapes, such as J-shaped. These changes do not exceed the technical principle of the present invention, and therefore will also be included in the protection scope of the present invention. At the same time, it is also mentioned above that the cross section of the second end of the nozzle 3 is semicircular. The purpose of such setting is that, compared with setting the cross section of the second end of the nozzle 3 to be circular, when the water flow is ejected from the second end of the circular nozzle 3, the water flow is columnar, and the water flow is relatively convergent, resulting in a relatively small impact area, which is not conducive to flushing the foam on the surface of the clothes during the rinsing process. In this embodiment, setting the lower half of the second end of the nozzle 3 to be semicircular can prevent the water from the upper half of the nozzle 3, so that all the water in the nozzle 3 is ejected from the semicircular nozzle of the lower half of the nozzle 3. In this way, due to the squeezing of the upper half of the nozzle 3, the water flow at the nozzle 3 will be ejected in a flatter state and at a faster speed, thereby increasing the impact area and impact force of the water flow, and improving the flushing effect of the foam on the surface of the clothes. In addition, those skilled in the art may also set the cross section of the second end of the nozzle 3 to other shapes, such as a flat rectangle or an ellipse, which are all conducive to improving the flushing effect of the foam on the surface of the clothes. It is worth mentioning that those skilled in the art should not set the opening area at the second end of the nozzle 3 too small, as too small an opening area will result in too small a water output, which is not conducive to improving the flushing effect. Those skilled in the art may adjust the shape of the opening at the second end of the nozzle 3 according to actual needs, and these changes do not exceed the technical principle of the present utility model, and therefore will also be included in the protection scope of the present utility model.

[0029] The main embodiments of the present invention have been introduced above, and some other embodiments of the present invention will be introduced next.

[0030] In a possible implementation manner, the nozzle 3 is provided with spray holes facing different directions, so that the water sprayed from the nozzle 3 can be sprayed from the spray holes in different directions.

[0031] The advantage of the above-mentioned setting method is that compared with the aforementioned setting that the water outlet direction of the nozzle 3 is fixedly set to the direction toward the inside of the inner drum, the water outlet direction of the nozzle 3 in this embodiment is set to be towards multiple directions. In this way, during the water filling stage of rinsing, no matter how the clothes inside the inner drum are distributed, the water sprayed from the spray hole can wet the clothes to be rinsed and then achieve rinsing, avoiding the situation where the clothes in the inner drum are in the blind corner of the spray range of the nozzle 3, resulting in the inability to wet the clothes to be rinsed, thereby affecting the rinsing effect.

[0032] In a possible implementation manner, the nozzle 3 is movably disposed at the water outlet of the water inlet pipe 2 so that the direction of the water flow sprayed from the nozzle 3 can be adjusted.

[0033] In the case of adopting the above-mentioned embodiment, compared with the aforementioned method of setting the water outlet direction of the nozzle 3 to be fixed, the nozzle 3 in this embodiment can adjust the direction of the water flow sprayed from the nozzle 3. When the number of clothes placed in the inner drum is large and the height of the clothes stacked is high, the water outlet direction of the nozzle 3 can be adjusted accordingly to spray water obliquely upward. Similarly, when the number of clothes in the inner drum is small, the water outlet direction of the nozzle 3 can be adjusted to spray water horizontally or obliquely downward. Therefore, in the process of rinsing clothes, the drum washing machine of the present invention can adaptably adjust the water outlet direction of the nozzle 3 according to the amount of clothes to be rinsed, so as to ensure that the water sprayed from the nozzle 3 can be sprayed on the clothes to the maximum extent, thereby achieving the purpose of saving water.

[0034] In a possible embodiment, the washing device also includes a water inlet pump and a liquid level sensor, the liquid level sensor is used to detect the liquid level in the inner drum, the liquid level sensor and the water inlet pump are communicatively connected with the controller of the washing device, so that the washing device can control the start and stop of the water pump according to the liquid level in the inner drum, and the washing device is configured to: in a first state, control the water inlet pump to inject water into the inner drum; in a second state, rinse the clothes in the inner drum.

[0035] When the above-mentioned embodiment is adopted, during the process of rinsing clothes, the liquid level in the inner drum is first obtained by the liquid level sensor. In the first state, that is, when the liquid level sensor detects that the liquid level in the inner drum is insufficient to rinse the clothes, the water inlet pump is controlled to inject water into the inner drum through the nozzle 3 on the water inlet pipe 2. The injected water first wets the clothes to be rinsed. After all the clothes are wetted, the injected water begins to gradually gather inside the inner drum. When the liquid level sensor detects that the water inside the inner drum has gathered to a certain height, the second state is entered and the washing machine starts to rinse the clothes in the inner drum.

[0036] The advantage of the above embodiment is that by arranging a liquid level sensor inside the inner drum and communicating the liquid level sensor and the water inlet pump with the controller of the washing machine, the automatic rinsing process of the clothes to be rinsed is realized under the premise of minimum water intake, thus saving rinsing water.

[0037] In the above embodiment, it is mentioned that by setting a liquid level sensor inside the inner drum, and communicating the liquid level sensor and the water inlet pump with the controller of the washing machine, the automatic rinsing process of the clothes to be rinsed under the premise of the minimum water inlet is realized. However, when facing some large clothes or clothes made of relatively absorbent materials, the clothes cannot be completely rinsed clean by just rinsing once. In order to solve this problem, this embodiment is proposed. Further, in this embodiment, the washing device also includes a turbidity sensor, which is used to detect the turbidity of the washing water in the inner drum. The turbidity sensor is communicated with the controller of the washing device so that the washing device can control whether to rinse the clothes according to the turbidity information of the washing water in the inner drum. The washing device is configured to: in the third state, control the water inlet pump to inject water into the inner drum; in the fourth state, rinse the clothes in the inner drum; in the fifth state, stop rinsing the clothes in the inner drum.

[0038] When the above-mentioned embodiment is adopted, during the process of rinsing clothes, the turbidity sensor is first controlled to obtain the turbidity information of the washing water inside the inner drum. In the third state, that is, the current water level in the inner drum is not enough to rinse the clothes, and the turbidity of the washing water in the drum is relatively high, and the clothes still need to be rinsed, the water inlet pump is controlled to inject water into the inner drum; in the fourth state, that is, the turbidity of the washing water in the drum is relatively high and the water level in the drum is capable of rinsing the clothes, the clothes in the inner drum are rinsed; in the fifth state, that is, the turbidity of the washing water in the drum is relatively low, and there is no need to continue rinsing the clothes, rinsing the clothes in the inner drum is stopped.

[0039] The advantages of the above embodiment are: the liquid level inside the inner drum during the rinsing process is obtained by the liquid level sensor to control the amount of water injected into the inner drum, and the turbidity information of the washing water during the rinsing process is detected by the turbidity sensor to control the number of rinses, thereby ensuring the cleanliness of the clothes under the premise of minimum water intake by using a small amount of water and multiple rinses, thereby improving the user experience.

[0040] In addition, those skilled in the art will appreciate that, although the above embodiment proposes using a turbidity sensor to detect the turbidity of washing water as a condition for determining the end of rinsing, this is not the only embodiment. Those skilled in the art may also use a preset number of rinses as a condition for determining the end of rinsing. For example, on the premise of meeting the minimum single water intake volume, rinsing may be stopped when the number of rinses reaches 10 or any other number. These changes do not exceed the technical principles of the present invention and are therefore included in the scope of protection of the present invention.

[0041] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the utility model, and is not intended to limit the protection scope of the utility model. Without departing from the principle of the utility model, those skilled in the art can adjust the above-mentioned structure so that the utility model can be applied to more specific application scenarios.

[0042] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
