Description

Technical Field

[0001] The present invention relates to a spraying device and a washing equipment using the same, belonging to the technical field of washing. Background Art

[0002] With the improvement of living standards, people's demand for health, hygiene and pollution-free in the process of cleaning daily necessities is increasing day by day, and users have higher and higher requirements for the functions of washing equipment. Taking washing machines as an example, most of the current washing machines are pulsator or drum washing machines. In the washing process, they rely on extremely destructive mechanical forces to wash clothes, which is very easy to damage the clothes. At the same time, in the process of use, washing daily clothes together is not only difficult to wash clean, but also easy to cause cross-contamination between clothes, which is very unhygienic. For infants and women, their clothes have special stains and are deeply contaminated, and ordinary washing methods are not easy to wash clean; at the same time, their skin is sensitive and their resistance to bacteria is weak. Washing clothes together is extremely easy to be infected, seriously affecting people's health and quality of life.

[0003] In response to the above problems, some improved products have also been introduced in the market, such as wall-mounted washing machines, children's washing machines, etc. However, these products are just "miniaturized" traditional pulsator washing machines and drum washing machines, which only meet the need to wash small pieces of clothes, but do not solve the problem of cross-contamination of clothes mixed washing. For infants with sensitive constitutions and the majority of women, this is still a difficult problem to solve.

[0004] The patent with the patent number 201822268982.9 discloses a kneading mechanism and an underwear washing machine. This patent simulates the hand-washing process through a flexible bag body and a kneading mechanism to achieve the effect of washing small pieces of clothes. However, different clothes are washed together, and there is a problem of cross-contamination between clothes; at the same time, the structure is complex and there are too many components, which is not conducive to the implementation of the actual solution.

[0005] In the prior art, when spraying and washing clothes, the washing effect on the whole clothes is often not good because the spraying range of the spraying device is narrow, and the stains on the clothes cannot be effectively removed. Assembling multiple spraying devices in the same washing chamber to wash clothes will increase the cost, complicate the assembly process, and at the same time make the water circuit system in the washing machine more complex, increasing the volume of the washing equipment. Summary of the Invention

[0006] In view of this, the present invention relates to a spraying device and a washing equipment having the same. The spraying device has a plurality of spraying inclined surfaces arranged at a specific angle, and spraying hole groups are arranged on different spraying inclined surfaces. Each spraying hole group includes a plurality of spraying holes. By arranging one such spraying device in the washing chamber, comprehensive washing and cleaning of the washed clothes can be achieved, and at the same time, all-round spraying and cleaning of the peripheral wall, bottom and top of the washing chamber can be realized. Targeted spraying and washing of different parts of the clothes solves the problem of small spraying range and poor spraying effect of the spraying device during the spraying washing process. The spraying washing method can solve the problem of damage to clothes caused by the high-intensity mechanical washing method of traditional washing machines by rotating and patting. The washing equipment in the present invention forms a plurality of washing chambers to realize separate washing of different clothes, and solves the problem of cross-contamination of different types of clothes during washing in a single barrel or a single washing chamber.

Embodiment 1

[0037] This embodiment relates to a spraying device and a washing device. The structure of the washing device and the spraying device in this embodiment will be specifically described below. The washing device in this embodiment can be applied to the field of clothing washing to spray and wash the clothes placed in the washing device.

[0038] Combined with Figure 1 and Figure 2 The structure of the washing device in this embodiment will be described. The washing device of the present invention is formed with two washing chambers, namely the first washing chamber A6 and the second washing chamber A8. When washing different clothes, different kinds of clothes can be placed in the first washing chamber A6 and the second washing chamber A8 respectively for washing, so as to realize the classified washing of clothes and solve the problem of cross-infection that is likely to occur when multiple clothes are washed in a single barrel or a single washing chamber.

[0039] The washing device is composed of a washing device water inlet A1, a washing device box body A2, a washing device drain outlet A3, a hinge A4, a top cover A5, a first washing chamber A6, a control panel A7, a second washing chamber A8, a washing chamber drain outlet A9, a box body base A10, a spraying device A11, control buttons A12, a detergent box A13, a first partition A14, a first pipeline chamber A15, a second pipeline chamber A16, a third pipeline chamber A17, a second partition A18 and other structures.

[0040] Among them, the first pipeline chamber A15 is used for arranging the water inlet pipeline and the drain pipeline of the washing device, the second pipeline chamber A16 is used for arranging the spraying pipelines in the spraying device; the third pipeline chamber A17 is used for arranging the water supply pipelines in the washing chamber.

[0041] A box body base A10, a washing device water inlet A1 and a washing device drain outlet A3 are arranged in the washing device box body A2. The top cover A5 is connected to the washing device box body A2 by a hinge A4. The first washing chamber A6 and the second washing chamber A8 are respectively arranged on the front and back sides of the washing device. The control panel A7 is in the middle of the two washing chambers, and control buttons A12 for controlling the opening and closing and the washing program are arranged thereon. In addition, under the first washing chamber A6, a first pipeline chamber A15 is arranged for arranging the water inlet pipeline and the drain pipeline, so that water flows in from the washing device water inlet A1 and enters the washing chamber for washing. Under the second washing chamber A8, a third pipeline chamber A17 is arranged for arranging the pipelines for supplying water to the washing chamber. Under the middle control panel A7, a second pipeline chamber A16 is arranged for arranging the spraying pipelines. The washing chamber and each pipeline chamber are separated by a first partition A14 and a second partition A18 respectively. Washing chamber drain outlets A9 are respectively arranged on the two partitions for draining the washing water in the washing chamber into the water circulation system during the circulating spraying washing process.

[0042] When water circulation is carried out in each washing chamber, water is discharged from the drainage outlet A9 of each washing chamber and the washing water flows back into the spray pipes of their respective washing chambers through a circulation water pump. The washing water of each washing chamber returns to its respective spray device A11 through the water inlet pipe B9 of the spray device, and then the spray device A11 sprays and washes each washing chamber. The beneficial effects are as follows: The washing equipment in this embodiment is provided with two or more washing chambers to realize the classified washing of the laundry, preventing cross-infection of different types of laundry during the cleaning process. The washing water in each washing chamber can be circulated and sprayed for washing within its own washing chamber, which can save water while enhancing the washing effect, increase the solubility of the detergent in the washing chamber, and the circulating washing can also increase the cleanliness of the washing, achieving low-cost and high-efficiency spray washing.

[0043] As Figures 3 - 5 shown, the structures of the spray device in this embodiment are schematically shown from different angles.

[0044] A spray device disclosed in this embodiment includes a housing. The spray device is provided with a water inlet and a spray outlet; a spray surface, the spray outlet of the spray device is formed on the spray surface, and the spray surface protrudes outward relative to the housing; the spray surface includes a plurality of spray inclined surfaces; a plurality of spray holes are formed on the spray inclined surfaces. The plurality of spray inclined surfaces form a polyhedron protruding outward, and the apex angle at the protruding part of the polyhedron is between 90 degrees and 180 degrees. In this embodiment, the apex angle at the protruding part of the polyhedron specifically refers to the angle formed by one side in the width direction of the first spray inclined surface and one side in the width direction of the second spray inclined surface on the same side. The housing of the spray device in this embodiment includes a water storage chamber B5, a sealing plate B6, an assembly plate B7, and a wedge-shaped water inlet B8. A water storage chamber B5 is formed on the housing, an assembly plate B7 is arranged on the water storage chamber B5, and a sealing plate B6 is arranged on the assembly plate B7. The sealing plate B6 is used to realize the sealing connection between the spray surface and the water storage chamber B5. A wedge-shaped water inlet B8 is connected to the lower end of the water storage chamber B5, and the water inlet end of the wedge-shaped water inlet B8 is connected to the water inlet pipe B9. When washing clothes, water flows into the water storage chamber B5 through the water inlet pipe B9 and the wedge-shaped water inlet B8. When the water storage chamber B5 is filled with water, the water is sprayed out from the spray holes of the plurality of spray inclined surfaces formed by the spray surface to realize the spraying function on the washing chamber.

[0045] In this embodiment, each washing chamber is provided with at least one such spray device. The housing of the spray device is arranged inside the peripheral wall of the washing chamber, and the spray surface of the spray device is arranged on the peripheral wall surface of the washing chamber.

[0046] In this embodiment, the spray inclined surface is a straight surface. In different implementation scenarios, the spray inclined surface can be a straight surface and / or a curved surface.

[0047] The spraying surface in the spraying device includes a first spraying inclined surface group, a second spraying inclined surface group, a third spraying inclined surface group, and a fourth spraying inclined surface group; the first spraying inclined surface of the first spraying inclined surface group is arranged obliquely upward; the second and third spraying inclined surfaces of the second and third spraying inclined surface groups are arranged obliquely downward; the fourth spraying inclined surfaces of the fourth spraying inclined surface group are arranged on the left and right sides of the spraying surface.

[0048] The first spraying inclined surface group can be formed by splicing a plurality of first spraying inclined surfaces or by one first spraying inclined surface. The second spraying inclined surface group can be formed by splicing a plurality of second spraying inclined surfaces or by one second spraying inclined surface. The third spraying inclined surface group can be formed by splicing a plurality of third spraying inclined surfaces or by one third spraying inclined surface. The fourth spraying inclined surface group is composed of at least two fourth spraying inclined surfaces, one fourth spraying inclined surface is arranged on the left side of the spraying surface, and the other fourth spraying inclined surface is arranged on the right side of the spraying surface.

[0049] Specifically, as Figures 3 - 5 It can be seen that in this embodiment, the first spraying inclined surface group includes a first spraying inclined surface B1, the second spraying inclined surface group includes a second spraying inclined surface B2, the third spraying inclined surface group includes a third spraying inclined surface B3, and the fourth spraying inclined surface group includes two fourth spraying inclined surfaces B4; the first, second, and third spraying inclined surfaces are all long strip-shaped inclined surfaces.

[0050] The spraying surface successively forms a first spraying inclined surface B1, a second spraying inclined surface B2, and a third spraying inclined surface B3 from top to bottom. One side edge in the length direction of the first spraying inclined surface B1 is connected to one side edge in the length direction of the second spraying inclined surface B2, and the other side edge in the length direction of the second spraying inclined surface B2 is connected to one side edge in the length direction of the third spraying inclined surface B3; one fourth spraying inclined surface B4 formed on the left side of the spraying surface is connected to one side edge in the width direction of the first spraying inclined surface B1, the second spraying inclined surface B2, and the third spraying inclined surface B3, and the other fourth spraying inclined surface B4 formed on the right side of the spraying surface is connected to the other side edge in the width direction of the first spraying inclined surface B1, the second spraying inclined surface B2, and the third spraying inclined surface B3.

[0051] The second spraying inclined surface B2 forms a first acute angle with the housing, and the third spraying inclined surface B3 forms a second acute angle with the housing, and the first angle is smaller than the second angle. That is, the second spraying inclined surface B2 and the third spraying inclined surface B3 are both arranged obliquely downward on the spraying surface, and the inclination angle of the third spraying inclined surface B3 is larger. Therefore, the third spraying inclined surface B3 can spray and clean the bottom of the washing chamber, especially the corner positions at the bottom. The first spraying inclined surface B1 is arranged obliquely upward on the spraying surface and can spray and wash the bottom of the washing chamber.

[0052] The lengths of the sides along the length direction of the first, second, and third spray inclined surfaces are the same. The lengths of the sides along the width direction of the second spray inclined surface are greater than those of the first and third spray inclined surfaces along the width direction, so that the area of the second spray inclined surface is greater than that of the first and third spray inclined surfaces. A plurality of spray holes are provided on the first spray inclined surface, the second spray inclined surface, the third spray inclined surface, and the two fourth spray inclined surfaces.

[0053] A first spray hole group is formed on the first, third, and the two fourth spray inclined surfaces. The first spray hole group includes a plurality of first spray holes. The plurality of first spray holes are evenly distributed on the first, third, and fourth spray inclined surfaces. The aperture of the first spray hole is small and is densely distributed on the first, third, and fourth spray inclined surfaces, mainly used for auxiliary washing and spray cleaning of the chamber wall in the washing chamber during the clothing washing process, and also for comprehensive auxiliary washing of various parts of the clothing.

[0054] A second spray hole group and a third spray hole group are formed on the second spray inclined surface B2; the second spray hole group includes two second spray hole units, and each second spray hole unit includes a plurality of second spray holes B11; the third spray hole group includes a plurality of third spray holes B12; the two second spray hole units are respectively arranged on the left and right sides of the second spray inclined surface, and the third spray hole group is arranged in the middle of the second spray inclined surface; and the hole densities of the two second spray hole units are the same, and the hole density of the second spray hole unit is less than that of the third spray hole group; the aperture of the second spray hole B11 is larger than that of the third spray hole B12.

[0055] The second spray hole B11 has a larger aperture and a large amount of water output, which is used to promote water flow agitation during clothing spray washing, form vortex washing, and enhance the washing effect of the clothing. The third spray hole group is arranged in the middle of the second spray inclined surface, and the hole density of the third spray hole group is large. The third spray hole group is one of the main spray hole groups during the clothing washing process, which can not only perform targeted centralized spray cleaning on the dirt of the clothing, but also improve the washing efficiency and make the washing process efficient and energy-saving. The omnidirectional spraying of the spray surface on the washing chamber enables the detergent to be quickly and completely dissolved in the washing water. During the circulating spraying process, the washing water dissolved with the detergent is sprayed out through the first spray hole B10, the second spray hole B11, and the third spray hole B12 to perform omnidirectional spraying on the washing chamber and the clothing; especially the washing water sprayed out from the third spray hole B12 enables the washing water dissolved with the detergent to fully act on the clothing, realizing rapid spray decontamination and cleaning of the clothing to be washed.

[0056] Furthermore, the setting of the spray holes of this spray device is not limited to the above specific examples, and the aperture, hole density, and distribution position of the spray holes on different spray inclined surfaces can be changed according to the structure of the washing chamber and the clothing washing requirements.

[0057] In summary, in this embodiment, the spraying surface of the spraying device includes a first spraying inclined surface B1, a second spraying inclined surface B2, a third spraying inclined surface B3, and two fourth spraying inclined surfaces B4. The first spraying inclined surface B1, the second spraying inclined surface B2, and the third spraying inclined surface B3 are all long strip-shaped inclined surfaces in this embodiment, so that the spraying area is larger and the effective spraying area is wider. When water is sprayed out on the above different spraying inclined surfaces, it can be sprayed onto the surrounding, top, and bottom of the washing chamber from different angles, realizing the full coverage of the washing chamber by the sprayed water. The beneficial effects are as follows: ensuring that the clothes in the washing chamber can be sprayed and washed in all directions, and the wide spraying range of the spraying device realizes a dead-angle-free spraying and washing of the clothes. During the washing process, the sprayed water from the spraying device can also act on the top, peripheral wall, and bottom of the washing chamber, realizing the spraying and flushing of the washing chamber, flushing and cleaning the dirt accumulated in the washing chamber, preventing the stains remaining in the previous laundry process from re-contaminating the clothes in the next laundry process, ensuring the cleanliness of the washing chamber after each washing process, further improving the washing effect of the washing equipment on the clothes and the cleanliness of the clothes. The combination of the full-range spraying and the circulating spraying of the washing chamber increases the solubility of the detergent and improves the detergent dissolution efficiency, realizing efficient washing.

[0058] The above has specifically shown and described the exemplary embodiments of the present disclosure. It should be understood that the present disclosure is not limited to the detailed structures, settings, or implementation methods described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent settings included within the spirit and scope of the appended claims.
