Description

Technical Field

[0001] The present invention relates to a spray device and a washing device having the same. Specifically, the present invention relates to a floor-standing spray device and a washing device having the same. The present invention belongs to the technical field of washing equipment. Background Art

[0002] As living standards improve, people's expectations for laundry are becoming increasingly demanding. Not only do they want clean clothes, but they also want washing machines with sterilization and disinfection capabilities. For women's and infant clothing, the washing process must ensure both cleanliness and sterilization rates due to the specific nature of stains and skin sensitivity. Conventional washing machines not only use high mechanical forces, which can damage clothing, but also fail to meet user needs for sterilization and disinfection.

[0003] Conventional washing machines typically use a rotating impeller or drum-type mechanical beating to complete the washing process, which is not only prone to damaging clothing but also occupies a large area. While the spray-type washing method used by small washing machines makes mechanical washing gentler, the angle of the nozzle and the spray area it covers fall far short of achieving the desired cleaning effect. Furthermore, the spray water flow is monotonous, unable to adjust the flow for different garments. The entire washing process uses the same single spray method, resulting in a monotonous, top-down spray method that takes a long time to clean clothes and requires a large amount of wash water, resulting in significant waste of water and electricity.

[0004] In order to increase the washing space for clothes, ordinary clothes washing machines often use the drainage method of the corners of the washing chamber side walls. This is not only not conducive to the rotation of the water flow during washing, but also easily causes small pieces of clothing to block the drain outlet, resulting in poor drainage after washing and prolonged drainage time. Summary of the Invention

[0005] In view of this, the present invention provides a floor-standing spray device and a washing machine having the same. The floor-standing spray device of the present invention is fixedly arranged at the bottom of the washing chamber formed by the washing machine. The outer peripheral surface of the spray head of the floor-standing spray device forms a curved surface extending outward from the upper end of the barrel, and a plurality of spray holes are formed on the curved surface; the floor-standing spray device is also provided with a drainage hole and a water spray hole that generates a swirl in the washing chamber. The present invention solves the problem that spray washing cannot perform comprehensive and dead-angle spray cleaning on clothes and the washing chamber; solves the problem that a single spray mode consumes a large amount of water and electricity and takes a long time to wash during ordinary spray washing; and solves the problem that the drain outlet is easily blocked by small pieces of clothing.

[0006] Specifically:

[0007] The present invention relates to a floor-standing spray device, comprising: a base, a cylinder provided on the base, and a spray assembly provided on the cylinder; the cylinder forms an upper end and a lower end, and a first cavity extending vertically along the interior of the cylinder is formed between the upper end and the lower end;

[0008] The spray assembly includes a spray head located on the upper port of the cylinder. The outer peripheral surface of the spray head forms a curved surface extending outward from the upper port of the cylinder, and a plurality of spray holes are formed on the curved surface. A second cavity connected to the spray holes is formed in the outer peripheral wall or on the inner peripheral wall of the spray head. The second cavity is connected to the water supply pipe, which is introduced from the lower port of the base and passes through the first cavity to provide spray water for the second cavity.

[0009] Further optionally, one or more drainage holes are opened on the side wall of the base or the side wall of the cylinder close to the base.

[0010] Further optionally, a plurality of water spray holes are formed on the side wall of the base or the side wall of the cylinder close to the base, and the water spray holes are distributed circumferentially at the bottom of the base or the cylinder.

[0011] Further optionally, a water spray pipe introduced from the lower port of the base is connected to the water spray hole; when the floor-standing spray device is working, multiple spray holes and / or multiple water spray holes spray water to the outside of the floor-standing spray device.

[0012] Further optionally, with the axis of the cylinder as the axis of symmetry, the drainage holes are symmetrically arranged on the side wall of the base or the side wall of the cylinder close to the base; a drainage pipe is introduced from the lower end of the base, and the drainage pipe is connected to the drainage hole. When the floor-standing sprinkler device performs drainage operation, water outside the floor-standing sprinkler device can flow from the drainage hole into the drainage pipe and be discharged through the drainage pipe.

[0013] Further optionally, a plurality of water spray holes are formed obliquely in clockwise or counterclockwise direction in different tangential directions of the cylinder, and a vortex can be formed when the external water level of the floor-standing sprinkler device is higher than the highest position of the water spray hole.

[0014] Further optionally, the water spray hole is a circular hole; the opening direction of each water spray hole forms an angle β with the tangent plane of the cylinder surface at the position of the water spray hole, and the value range of the angle β is (0°, 90°).

[0015] Further optionally, the plurality of water spray holes are symmetrically arranged on both radial sides of the cylinder in the transverse direction of the cylinder; and are distributed in a stepped manner along the axis of the cylinder in the vertical direction of the cylinder.

[0016] Further optionally, the outer peripheral surface of the cylinder is an inwardly concave arc-shaped curved surface, and the diameter of the upper port of the cylinder is larger than the diameter of the lower port of the cylinder.

[0017] Further optionally, a detergent box is provided on the upper part of the first cavity, which is used to hold detergent, and the second cavity is connected to the detergent box; when detergent needs to be added, the detergent flows from the detergent box into the second cavity, and the detergent is mixed with the water in the second cavity and sprayed out from the spray hole.

[0018] The present invention also relates to a washing device with a floor-standing spray device, which includes a washing chamber, a base fixedly arranged at the bottom of the washing chamber, and water in the washing chamber is drained through a drainage hole; the washing water is sprayed into the washing chamber through a water spray hole and / or a spray hole.

[0019] Beneficial effects:

[0020] The present invention discloses a floor-standing spray device, the base of which is fixedly arranged at the bottom of a washing chamber formed by a washing device. Preferably, it is arranged in the middle of the bottom of the washing chamber, and a spray head with an outer peripheral surface being an upwardly extending curved surface is arranged on it, and a drainage hole and a water spray hole are arranged below it.

[0021] When water is sprayed from the spray holes on the spray head into the washing chamber, it can fully act on the inner wall and bottom of the washing chamber, solving the problem of dead corners and incomplete spraying in the washing chamber during the spraying process of general spray devices. The clothes can be fully sprayed and washed to make the clothes more thoroughly clean. While washing the clothes, it can also play a role in cleaning the washing chamber and keep the inside of the washing chamber clean.

[0022] The floor-standing shower device of the present invention is provided with a water spray hole. When water is sprayed from the water spray hole into the washing chamber, a vortex is generated in the water in the washing chamber that is not covered by the water spray hole. During the washing process, the water spray hole forms an annular vortex in the washing chamber, especially around the drain hole, which prevents clothing, especially small items of clothing, from clogging the drain hole. This makes the drainage process of the washing chamber through the drain hole of the floor-standing shower device smoother, without small items of clothing blocking the drain port, thereby improving drainage efficiency. The annular vortex formed by the water spray hole in the washing chamber drives the clothing to rotate. During the washing process, when the water spray hole and the shower hole jointly spray water outward into the washing chamber, the clothing in the washing chamber can be driven to rotate, thereby increasing water agitation and the washing effect.

[0023] The floor-standing spray device of the present invention enables the washing chamber equipped with it to achieve integrated upper and lower water supply and drainage. During the washing process, water flows from the spray head at the upper end of the floor-standing spray device to spray and wash the clothes. Water is sprayed from the spray hole at the lower end, causing the clothes to rotate, preventing the clothes from clogging the drain hole. The water is discharged from the drain hole at the lower end of the floor-standing spray device. Throughout the washing process, the washing water flows through the four sides of the washing chamber and is discharged from the middle of the washing chamber. The placement of the floor-standing spray device in the washing chamber ensures that the water flows fully onto the clothes in the washing chamber, increasing the agitation of the water flow and making the clothes clean.

[0042] [Example 1]

[0043] 1 (a) is a top view of the washing apparatus according to an embodiment of the present invention, and FIG. 1 (b) is a front view of the washing apparatus according to an embodiment of the present invention when the top cover is opened; Figure 2 The side cross-sectional view of the washing device of the present invention is shown below in conjunction with Figure 1 (a), Figure 1 (b) and Figure 2 The structure of the washing machine in this embodiment will be described in detail.

[0044] The washing machine in this embodiment comprises a body A3. Body A3 consists of a base A12 and a top cover A8. A sidewall of base A12 is connected to a side edge of top cover A8 via a hinge A9, allowing top cover A8 to be rotatably mounted on base A12. Users can lift top cover A8 to place laundry into a washing chamber A11 formed within the body. The rear end of the base, near the ground, is provided with a water inlet A1 and a drain outlet A2. A display screen A4 is provided on the outer surface of top cover A8. Display screen A4 includes a pause button A5, a power button A6, and a digital display A7. The pause button A5 and power button A6 are used to control the basic operation of the washing machine in this embodiment. The user can view the program status of the washing machine via the digital display A7. Inside body A3, below washing chamber A11, is a pipe chamber A16, which houses the circulating pump A14 and the various pipes A15 in the water circuit of the washing machine. The washing chamber A11 and the pipe chamber A160 are separated by a partition 13. The floor-standing spray device A10 is arranged in the middle of the washing chamber A11 and is arranged perpendicular to the bottom of the washing chamber A11.

[0045] Figure 3This is a schematic diagram of the water piping connections for the washing machine in this embodiment. When water is flowing into the washing machine, inlet valve A17 is open and drain valve A18 is closed. Water flows from the washing machine's water inlet A1 through inlet valve A17, passes through right-angle pipe A19, and flows through second T-shaped three-way valve A32, ultimately reaching first T-shaped three-way valve A26. Water then enters floor-standing spray device A10 through floor-standing spray device inlet A25, completing the water intake process. When the washing cycle is complete, inlet valve A17 and drain valve A18 are closed, leaving a certain amount of wash water in washing chamber A11. The washing water in the washing chamber A11 flows from the washing chamber drain connector A24, through the washing chamber drain pipe A23, through the right-angle adapter A22 to the circulation pump water inlet A21, and then enters the circulation pump A14. It then flows out of the circulation pump A14, passes through the circulation pump water outlet A20 to the first T-type three-way valve A26, and finally passes through the floor-standing spray device water inlet A25 to the floor-standing spray device A10 for circulating spray washing. After the clothes are washed, they are drained. Open the drain valve A18, close the water inlet valve A17, and the washing water flows through the washing chamber drain pipe A23, through the circulation pump A14, reaches the first T-type three-way valve A26, then passes through the drain valve A18, and finally is discharged from the washing equipment drain outlet A2. During the drainage process, the circulation pump A14 remains on to accelerate the drainage speed of the washing chamber A11.

[0046] like Figure 4 The figure shows a schematic structural diagram of a floor-standing spray device in this embodiment. This embodiment discloses a floor-standing spray device A10 comprising: a base A31, a barrel A33 disposed on the base A31, and a spray assembly disposed on the barrel; the barrel forms an upper barrel port and a lower barrel port, with a first cavity extending vertically along the barrel interior formed between the upper barrel port and the lower barrel port;

[0047] The spray assembly includes a spray head A34 located on the upper port of the cylinder. The outer peripheral surface of the spray head forms a curved surface extending outward from the upper port of the cylinder, and a plurality of spray holes A28 are formed on the curved surface. A second cavity connected to the spray holes A28 is formed in the outer peripheral wall or on the inner peripheral wall of the spray head. The second cavity is connected to the water supply pipe, which is introduced from the lower port of the base and passes through the first cavity to provide spray water for the second cavity.

[0048] One or more drainage holes are provided on the side wall of the base of the floor-standing sprinkler device or on the side wall of the cylinder body near the base. Preferably, the floor-standing sprinkler device is provided with multiple drainage holes, which are symmetrically arranged on the side wall of the base or on the side wall of the cylinder body near the base with the axis of the cylinder body as the axis of symmetry. A drainage pipe is introduced from the lower end of the base and connected to the drainage hole. When the floor-standing sprinkler device is draining, water outside the floor-standing sprinkler device can flow from the drainage hole into the drainage pipe and be discharged through the drainage pipe.

[0049] In this embodiment, the floor-standing spray device A10 has two drainage holes A30 on the side wall of the barrel A33 near the base A31. The two drainage holes A30 are symmetrically arranged on the side wall of the barrel A33 near the base A31, with the axis of the barrel A33 as the axis of symmetry. A drainage pipe is introduced from the lower end of the base A31 and connected to the two drainage holes A30. When the floor-standing spray device A10 is draining, water outside the floor-standing spray device A10 can flow into the drainage pipe from the drainage hole A30 and be discharged through the drainage pipe. When the washing chamber is drained, the water can be drained symmetrically from both ends of the floor-standing spray device A10. The beneficial effect is that the provision of two drainage holes can increase the drainage rate of the washing chamber. Compared with the prior art that provides a single drainage hole or drainage outlet in the washing chamber, it avoids the pulling and damage of clothes caused by the negative pressure of the water flow during the drainage process.

[0050] A plurality of water spray holes are formed on the side wall of the base of the floor-standing sprinkler device or on the side wall of the cylinder near the base, and the water spray holes are distributed circumferentially on the bottom of the base or the cylinder. The water spray pipe introduced from the lower port of the base is connected to the water spray hole; when the floor-standing sprinkler device is in operation, the plurality of spray holes and / or the plurality of water spray holes spray water to the outside of the floor-standing sprinkler device. The plurality of water spray holes are formed obliquely in a clockwise or counterclockwise direction in different tangential directions of the cylinder, and a vortex can be formed when the external water level of the floor-standing sprinkler device is higher than the highest position of the water spray holes. The plurality of water spray holes are symmetrically arranged on both sides of the cylinder in the transverse direction of the cylinder; in the vertical direction of the cylinder, they are distributed in a stepped manner along the axis of the cylinder.

[0051] Further optionally, the water spray hole is a circular hole; the opening direction of each water spray hole forms an angle β with the tangent plane of the cylinder surface at the position of the water spray hole, and the value range of the angle β is (0°, 90°).

[0052] Specifically, in this embodiment, two water spray holes A29 are formed on the side wall of the barrel A33 of the floor-standing spray device A10 near the base A31. The water spray holes A29 are symmetrically arranged on both radial sides of the barrel A33 in the horizontal direction. In the vertical direction of the barrel A33, the water spray holes A29 are distributed in a stepped manner along the axis of the barrel A33. When the water in the washing chamber A11 exceeds the highest position of the two water spray holes A29, the water sprayed from the two water spray holes A29 forms a ring-shaped vortex water flow around the floor-standing spray device A10, simultaneously causing the clothes and water in the washing chamber A11 to stir, achieving vortex washing of the clothes. While the water spray holes A29 spray water outward, the spray holes A28 in the spray head also spray water outward to act on the clothes in the washing chamber A11, achieving a dual washing effect of spray washing and vortex washing, making the clothes cleaner. During washing, if clothing approaches the annular swirling water flow belt formed by the water spray holes in the washing chamber A11, it will be driven away by the centrifugal force generated by the annular swirling water flow belt. This has the beneficial effect of effectively preventing clothing, especially small items, from being adsorbed near the drain hole and causing blockage of the drain hole. This improves drainage efficiency during the subsequent drainage process.

[0053] In this embodiment, the outer circumference of the barrel A33 is a concave curved surface, and the diameter of the upper end of the barrel is larger than that of the lower end. A detergent box A27 is also located above the first cavity, which is used to hold detergent. The second cavity is connected to the detergent box A27. When detergent is added, the detergent flows from the detergent box A27 into the second cavity, where it mixes with the water in the second cavity and is sprayed out through the spray hole A28.

[0054] As shown in FIG6(a), the arrow indicates the rotation direction of the annular swirling water flow band formed when the water spray hole A29 sprays water into the washing chamber.

[0055] like Figure 5 The figure shows the water system diagram of the washing machine with a floor-standing spray device in this embodiment. The water system diagram is a schematic diagram of the water system layout in the washing machine. In order to distinguish the names of the pipes and valves in the actual equipment from those in the water system, Figure 5 Zhongyu Figure 3 or Figure 4 The word "waterway" is added before the corresponding structure name to distinguish it. Figure 5 It is a schematic diagram of the water system of the washing equipment in this embodiment, which is not equivalent to the specific pipe connection status of the washing equipment in this embodiment.

[0056] like Figure 5As shown, a water inlet pipe B13 and a drain pipe B14 are connected to the water washing chamber B11. A circulating return pipe B15 is connected to the water inlet pipe B13 and the drain pipe B14. A water inlet three-way valve B2 is installed at the intersection of the water inlet pipe B13 and the circulating return pipe B15. A water inlet valve B1 is installed between the water inlet of the water inlet pipe B13 and the water inlet three-way valve B2 to control the water inflow into the water washing chamber B11.

[0057] A three-way water drain valve B4 is installed at the intersection of the circulating return water pipe B15 and the drain pipe B14. A water drain valve B5 is installed between the drain outlet of drain pipe B14 and the three-way water drain valve B4 to control the outflow of drain pipe B14. In the water washing chamber B11, the water spray hole B9 is connected to the aforementioned circulating return water pipe B15 via a swirl water inlet pipe B16. A three-way water circulation valve B3 is installed at the intersection of the swirl water inlet pipe B16 and the circulating return water pipe B15. In this embodiment, a filter B8 is installed at the drain outlet B7 of the water washing chamber B11. This filter B8 is used to filter the wash water flowing out of the water washing chamber B11, trapping hair, cloth lint, and small debris in the wash water in the filter B8, thereby preventing impurities from damaging the water system of the washing equipment during the washing process. A water circulation pump B6 is provided in the drainage pipe B14 between the drainage port B7 of the water washing chamber and the three-way valve B4 for draining the water. During the circulation washing process, the water in the water washing chamber B11 is circulated through the drainage pipe B14, then through the circulation return pipe B15 and the swirl water inlet pipe B16, and then from the water spray hole B9 back to the water washing chamber B11; or during the circulation washing process, the water in the water washing chamber B11 is circulated through the drainage pipe B14. , and then passes through the circulation return pipe B15 and the water inlet pipe B13 through the water channel spray inlet B10, and is sprayed and circulated back to the water channel washing chamber B11; or in the process of circulation washing, the washing water in the water channel washing chamber B11 flows through the drainage pipe B14, and then passes through the circulation return pipe B15, and then flows into the swirl water inlet pipe B16 and the water inlet pipe B13 respectively, and finally circulates back to the water channel washing chamber B11 from the water channel spray hole B9 and the water channel spray inlet B10 at the same time.

[0058] exist Figure 5 Schematic diagram of the water system. Figure 5 The water inlet valve B1 and Figure 3 The water inlet valve A17 corresponds to; Figure 5 The water inlet three-way valve B2 corresponds to the first T-type three-way valve A26; Figure 5 The water circulation three-way valve B3 is not in Figure 3 Draw in, Figure 5 Corresponding to the water drainage three-way valve B4 Figure 3 The second T-type three-way valve A32; Figure 5 Corresponding to the water drain valve B5 Figure 3 Drain valve A18 in; Figure 5 The water circulation pump B6 corresponds to Figure 3 Circulation pump A14 in; Figure 5 The drain outlet B7 of the water washing chamber is Figure 3 Not marked, but related to Figure 3 Connect to the washing chamber drain connector A24; Figure 5 The water channel spray hole B9 and Figure 4 The water spray holes in the Figure 5 The water spray inlet B10 in the water channel corresponds to Figure 4 Spray hole A28 in the middle; Figure 5 The water channel washing chamber B11 corresponds to the washing chamber A11.

[0059] according to Figure 5 It can be seen that the water system of the washing equipment can be controlled to perform the following washing processes, but is not limited to the following washing processes:

[0060] When spraying water into washing chamber B11, water inlet valve B1 is opened, allowing external water to flow through three-way water inlet valve B2 and into washing chamber B1 via spray inlet B10, thereby feeding laundry B12. After the first spray wash, or when the water level in washing chamber B1 reaches a preset or set level, water from washing chamber B11 flows through drain outlet B7 with filter B8 and into circulating pump B6. The preset or set water level here refers to the user-preset water level in washing chamber B1 or the level set by the washing machine based on the laundry load, such as the number of items or material.

[0061] During the circulation wash cycle in water washing chamber B11, wash water flowing from water circulation pump B6 passes through water drainage three-way valve B4 and reaches water circulation three-way valve B3. It then enters water washing chamber B11 through water spray holes B9 and water spray inlet B10, respectively, where it washes the clothes in water washing chamber B11 using both spray and vortex methods. At this point, water inlet valve B1 and water drainage valve B5 are both closed, and water flows through water circulation pump B6, continuing the circulation wash cycle until the laundry is washed.

[0062] When draining the water channel washing chamber drain outlet B7 after washing is completed, the water channel inlet valve B1 and the water channel circulation three-way valve B3 are closed, the water channel drain valve B5 is opened, and the water flows from the water channel washing chamber drain outlet B7 through the water channel circulation pump B6 and is discharged from the washing equipment through the water channel drain valve B5.

[0063] While the exemplary embodiments of the present disclosure have been specifically illustrated and described above, it should be understood that the present disclosure is not limited to the detailed structures, configurations, or implementations described herein; rather, the present disclosure is intended to encompass various modifications and equivalent configurations within the spirit and scope of the appended claims.
