[0001] This invention relates to the field of household appliance technology, and in particular to a washing device and a control method for the washing device. Background Technology

[0002] With the development of technology and the acceleration of the pace of life, washing machines have not only gradually become an indispensable household appliance in daily life, but are also becoming increasingly intelligent. Currently, washing machines can automatically control water inlet / drainage, automatically wash / spin-dry / dry, and automatically dispensing detergent, thereby further reducing the user's workload and improving the user experience.

[0003] Washing machines include front-loading washing machines and top-loading washing machines. Top-loading washing machines include a casing and a washing tub assembly housed within the casing. A steam generator may be installed at the bottom of the washing tub assembly to enable the top-loading washing machine to perform steam washing.

[0004] However, top-loading washing machines with steam washing functions do not spin-dry well. Summary of the Invention

[0005] This invention provides a washing device and a control method for the washing device. During the spin-drying process, a negative pressure is formed near the protrusion of the annular disc seat to draw dry air from the outside into the inner tub through the through hole of the top cover, thereby reducing the humidity in the inner tub. This not only improves the spin-drying effect but also increases the spin-drying efficiency.

[0006] In a first aspect, the present invention provides a washing device, comprising a housing, an annular base, a top cover, a washing tub assembly, and a steam generator; the annular base is disposed at the open end of the housing, the top cover covers the side of the annular base opposite to the housing, and the housing, the annular base, and the top cover form a receiving cavity; the washing tub assembly is disposed in the receiving cavity, the steam generator is disposed at the bottom of the washing tub assembly, and the steam generator communicates with the inner cavity of the washing tub assembly; the top cover is provided with a through hole penetrating the top cover, and the inner ring side of the annular base is provided with a protrusion protruding toward the receiving cavity.

This will draw dry air from the outside into the inner cavity of the washing tub assembly through the through hole in the top cover, thereby reducing the humidity in the inner cavity of the washing tub assembly. This not only helps to improve the spin-drying effect, but also helps to increase the spin-drying efficiency.

Detailed Implementation

[0035] In related technologies, a pulsator washing machine includes a casing and a washing tub assembly housed within the casing. A steam generator is located at the bottom of the washing tub assembly. The steam generator heats and vaporizes the water entering the washing tub assembly to form steam, thus enabling the pulsator washing machine to perform steam washing. However, during the spin-drying process, the aforementioned pulsator washing machines with steam washing function, like ordinary pulsator washing machines, rely solely on centrifugal force to remove water from the clothes. This results in poor spin-drying performance and relatively low efficiency.

[0036] To address the aforementioned technical problems, this invention provides a washing device and a control method for the washing device. The washing device includes a housing, an annular disc base, a top cover, a washing tub assembly, and a steam generator. By placing the annular disc base at the open end of the housing and covering the side of the annular disc base away from the housing with the top cover, the housing, the annular disc base, and the top cover form a receiving cavity. By placing the washing tub assembly within the receiving cavity, not only can the housing, the annular disc base, and the top cover protect the washing tub assembly, but the aesthetics of the washing device are also improved.

[0037] By placing the steam generator at the bottom of the washing tub assembly and connecting it to the inner cavity of the washing tub assembly, the steam generated by the steam generator can enter the inner cavity of the washing tub assembly and wet the clothes to be washed, thus enabling the washing device to achieve the function of steam washing. This not only improves the cleaning effect but also helps to save water resources.

[0038] By providing a through hole through the top cover and a protrusion protruding towards the receiving cavity on the inner ring side of the annular disc seat, the airflow in the inner cavity of the washing tub assembly will accelerate through the protrusion during the spin-drying process of the washing device, and a negative pressure will be formed near the protrusion. This will draw dry air from the outside into the inner cavity of the washing tub assembly through the through hole in the top cover, thereby reducing the humidity in the inner cavity of the washing tub assembly. This not only helps to improve the spin-drying effect, but also helps to increase the spin-drying efficiency.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Reference Figures 1 to 8 As shown, this embodiment provides a washing device, which includes, but is not limited to, washing machines, shoe washing machines, and dishwashers.

[0043] The washing device in this embodiment includes a housing 100, an annular base 200, a top cover 300, a washing tub assembly 400, and a steam generator 500.

[0044] For example, the housing 100 includes, but is not limited to, a metal housing 100, a plastic housing 100, or a housing 100 composed of a combination of metal and plastic. The annular tray 200 includes, but is not limited to, a metal tray 200, a plastic tray 200, or a tray 200 composed of a combination of metal and plastic. The top cover 300 includes, but is not limited to, a metal top cover 300, a plastic top cover 300, a glass top cover 300, or a top cover 300 composed of any two of metal, plastic, and glass. The plastic or glass portion of the plastic top cover 300, the glass top cover 300, or the combined top cover 300 may be configured as a transparent part to allow the user to observe the inner cavity of the washing tub assembly 400.

[0045] The annular disc base 200 is disposed at the open end of the housing 100. For example, the open end of the housing 100 is usually located at the top of the housing 100. The annular disc base 200 and the open end of the housing 100 can be fixedly connected by fasteners.

[0046] The top cover 300 covers the side of the annular disc base 200 away from the housing 100. For example, one end of the top cover 300 can be rotatably connected to one end of the annular disc base 200 near the rear side wall of the housing 100 so that the top cover 300 can be opened or closed relative to the annular disc base 200.

[0047] The housing 100, the annular disc base 200, and the top cover 300 form a receiving cavity, and the washing tub assembly 400 is placed in the receiving cavity. This not only protects the washing tub assembly 400 from the housing 100, the annular disc base 200, and the top cover 300, but also enhances the aesthetics of the washing device.

[0048] A steam generator 500 is disposed at the bottom of the washing tub assembly 400 and communicates with the inner cavity of the washing tub assembly 400. For example, the steam generator 500 has a heating element that heats the water entering the bottom of the washing tub assembly 400 to vaporize it into steam. The steam can enter the inner cavity of the washing tub assembly 400 and wet the clothes to be washed, enabling the washing device to perform steam washing. This not only improves the cleaning effect of the washing device but also helps to save water resources.

[0049] The top cover 300 is provided with a through hole 310 penetrating the top cover 300. For example, the shape of the through hole 310 includes, but is not limited to, a circle, an ellipse, a square, and a triangle. The number of through holes 310 can be set according to actual needs. The arrangement of the through holes 310 includes, but is not limited to, an array arrangement and a radial arrangement. The distribution area of ​​the through holes 310 on the top cover 300 can be the edge area of ​​the top cover 300, the central area of ​​the top cover 300, or other areas of the top cover 300. A filter screen can be installed on the through hole 310 to prevent external dust, impurities, etc. from entering the inner cavity of the washing tub assembly 400.

[0050] The inner ring side of the annular disk seat 200 is provided with a protrusion 210 protruding toward the receiving cavity. The shape of the protrusion 210 and the extension length along the inner ring side of the annular disk seat 200 can be set according to actual needs, as long as they can meet the requirements of this embodiment, and will not be described in detail here.

[0051] During the spin-drying process of the washing device, the airflow in the inner cavity of the washing tub assembly 400 will accelerate through the protrusion 210, and a negative pressure will be formed near the protrusion 210 to draw dry air from the outside into the inner cavity of the washing tub assembly 400 through the through hole 310 of the top cover 300, thereby reducing the humidity in the inner cavity of the washing tub assembly 400. This not only helps to improve the spin-drying effect, but also helps to improve the spin-drying efficiency.

[0052] Optionally, at least a portion of the through-holes 310 are located within the projection area of ​​the protrusion 210 on the upper cover 300 along the axial direction of the washing tub assembly 400. For example, all through-holes 310 may be configured to be located within the projection area of ​​the protrusion 210 on the upper cover 300 along the axial direction of the washing tub assembly 400, thereby allowing the negative pressure generated near the protrusion 210 to be better drawn in through the through-holes 310.

[0053] Optionally, the protrusion 210 extends along a portion of the inner ring side of the annular disc base 200. For example, the protrusion 210 may extend along the inner ring side of the annular disc base 200 on the side away from the rear sidewall of the housing 100, or the housing 100 may extend along the inner ring side of the annular disc base 200 on the side closer to the rear sidewall of the housing 100, or the housing 100 may extend along the inner ring side of at least one of the adjacent sides of the annular disc base 200 located on the rear sidewall of the housing 100.

[0054] Optionally, the protrusion 210 can be arranged around the inner ring side of the annular disc 200, thereby creating a better negative pressure effect when the airflow passes through the central hole of the annular disc 200, so as to better absorb dry air from the outside, improve the spin-drying effect, and increase the spin-drying efficiency.

[0055] Optionally, the surface of the protrusion 210 facing the accommodating cavity is curved, for example, it can be an arc-shaped surface, so as to ensure that the airflow can flow smoothly over the surface of the protrusion 210, generate a better negative pressure effect, and thus better absorb dry air from the outside, improve the spin-drying effect, and increase the spin-drying efficiency.

[0056] Optionally, the washing tub assembly 400 includes an outer tub 410, an inner tub 420, and a pulsator 430. The outer tub 410 is disposed within the housing 100, the inner tub 420 is rotatably disposed within the outer tub 410, and the pulsator 430 is rotatably disposed at the inner bottom of the inner tub 420. A steam generator 500 is disposed on the bottom wall of the outer tub 410 facing the inner tub 420, and the inner tub 420 has multiple small holes 421 on its wall, through which the steam generator 500 communicates with the inner cavity of the inner tub 420.

[0057] For example, the outer tub 410 can be made of plastic and can be suspended inside the housing 100 by a rod. The inner tub 420 can be made of stainless steel, and the tub wall of the inner tub 420 is provided with multiple small holes 421, through which water or steam can flow between the outer tub 410 and the inner tub 420. The impeller 430 is rotatably disposed inside the inner tub 420. The relative rotation of the impeller 430 and the inner tub 420 can drive the clothes to be washed to move, so that friction occurs between the clothes and between the clothes and the tub wall of the inner tub 420, thereby achieving the purpose of washing clothes.

[0058] Optionally, the inner wall of the inner barrel 420 is provided with a flow channel 600, which together with the inner wall of the inner barrel 420 forms a liquefaction flow channel 610. The liquefaction flow channel 610 extends along the axial direction of the inner barrel 420, and one end of the liquefaction flow channel 610 near the bottom of the inner barrel 420 has an opening.

[0059] Optionally, the flow channel 600 is provided with a nozzle 611. For example, there may be multiple nozzles 611. Multiple nozzles 611 can be arranged at intervals along the axial direction of the inner barrel 420. The nozzles 611 can be circular or other shapes. The size of the nozzles 611 can be set according to actual needs, as long as the ejection effect of the fluid in the liquefaction flow channel 610 can be guaranteed.

[0060] During application, the steam generator 500 vaporizes the water at the bottom of the outer drum to form steam, which enters the inner drum 420 through the small hole 421. When the impeller 430 rotates, the steam at the bottom of the inner drum 420 is accelerated into the liquefaction channel 610 through the opening at the bottom end of the liquefaction channel 610, and liquefies into large droplets in the liquefaction channel 610. The large droplets can be sprayed out through the top of the liquefaction channel 610 or through the nozzle 611 on the channel component 600 onto the items to be washed, so as to improve the cleaning effect.

[0061] Optionally, a detergent dispenser (not shown) is provided inside the liquefaction channel 610. The detergent dispenser has an opening that communicates with the liquefaction channel 610. When the liquid droplets in the liquefaction channel 610 flow through the opening of the detergent dispenser, they will carry some detergent into the clothes so that the detergent can come into even contact with the clothes, thereby improving the cleaning effect.

[0062] Optionally, the annular base 200 has a receiving groove on the side facing the housing 100, in which a main control board and a water inlet valve 220 are disposed. The water inlet valve 220 is electrically connected to the main control board, and the outlet of the water inlet valve 220 communicates with the area of ​​the washing tub assembly 400 where the steam generator 500 is installed. For example, the main control board can be a circuit board equipped with various electronic components. The main control board can not only control the opening and closing of the water inlet valve 220, but also control the washing tub assembly 400, the steam generator 500, and other parts of the washing device.

[0063] When the water inlet valve 220 is opened, the water flowing out of the outlet of the water inlet valve 220 can flow along the outer wall of the inner tub 420 into the bottom of the outer tub 410 and come into contact with the steam generator 500, so that the steam generator 500 can vaporize the water at the bottom of the outer tub 410 to achieve the function of steam washing.

[0064] Optionally, a control panel is provided on the side of the annular disc base 200 opposite to the housing 100. The control panel is electrically connected to the main control board, and the user can control the washing device by operating the control panel. For example, the control panel can be located at the end of the annular disc base 200 away from the rear side wall of the housing 100 for easy user operation.

[0065] Optionally, a humidity sensor is also installed in the accommodating cavity. The humidity sensor is electrically connected to the main control board and is used to detect the humidity inside the washing tub assembly 400. The main control board can control the washing device based on the humidity data measured by the humidity sensor.

[0066] Example 2

[0067] Figure 9 This is a flowchart illustrating the control method of the washing device provided in an embodiment of the present invention.

[0068] Reference Figure 9 As shown, this embodiment provides a control method for a washing device, which can be applied to the washing device of Embodiment 1. Optionally, the executing entity of this control method for the washing device includes, but is not limited to, the main control board of the washing device, a computer, and a mobile terminal. The following description uses the main control board as an example of the executing entity.

[0069] The control method for this washing device includes:

[0070] S100: The amount of water entering the bottom of the outer tank is controlled by the inlet valve.

[0071] For example, the main control board can control the amount of water entering the bottom of the outer tank by controlling the opening time of the water inlet valve.

[0072] S200: Control the steam generator to start, so as to convert the water entering the bottom of the outer tank into steam.

[0073] For example, the main control board can control the heating element of the steam generator to heat the water at the bottom of the outer tank.

[0074] S300: Obtain the first humidity in the inner barrel and determine whether the first humidity is not less than the first preset humidity.

[0075] If so, S310 controls the rotation of the impeller.

[0076] For example, the main control board can obtain the initial humidity in the inner tub through a humidity sensor and compare it with a first preset humidity. When the initial humidity is greater than or equal to the first preset humidity, the main control board can control the pulsator to rotate and start washing. The steam in the inner tub will gradually rise and be discharged from the vent in the top cover, which is the exhaust process of the washing device. Figure 4 When the initial humidity is less than the first preset humidity, you can wait for the steam generator to continue supplying steam to the inner tank until the initial humidity is greater than or equal to the first preset humidity.

[0077] S400: Obtain the remaining water level at the bottom of the outer tank and determine if the remaining water level is zero.

[0078] If so, S410 controls the inner drum to rotate.

[0079] For example, a water level sensor can be installed on the steam generator, or it can be installed at the bottom of the outer tub. The water level sensor detects the remaining water at the bottom of the outer tub. The main control board can obtain the remaining water level at the bottom of the outer tub through the water level sensor and determine if the remaining water level is zero. When the remaining water level is zero, the inner tub is controlled to rotate, starting the spin-drying process. The airflow speed in the inner tub increases, and the airflow speed further increases when it flows through the protrusion of the annular disc. A negative pressure is formed near the protrusion to draw outside air into the inner tub through the through-hole in the top cover. This is the air intake process of the washing device, see [reference needed]. Figure 5 When the remaining water level is greater than zero, the washing process can continue.

[0080] S500: Obtain the second humidity in the inner drum and determine whether the second humidity is not greater than the second preset humidity.

[0081] If so, S510, the control steam generator, impeller and inner tank will all stop.

[0082] For example, the main control board can obtain a second humidity level in the inner tub through a humidity sensor and compare it with a second preset humidity level. When the second humidity level is less than or equal to the second preset humidity level, the main control board can control the steam generator, impeller, and inner tub to stop, thus ending the spin-drying process. When the second humidity level is greater than the second preset humidity level, the spin-drying operation can continue until the second humidity level is less than or equal to the second preset humidity level.

[0083] In summary, the control method for the washing device provided in this embodiment can achieve the purpose of steam washing and spin drying by controlling the washing device. Moreover, since the control method of the washing device of the present invention is applied to the above-mentioned washing device, the control method of the washing device not only helps to improve the cleaning effect and save water resources, but also helps to improve the spin drying effect and increase the spin drying efficiency during the spin drying process of the washing device.
