[0001] This invention belongs to the field of washing equipment, specifically, it relates to a spray control method for washing equipment and a washing equipment. Background Technology

[0002] With the advancement of science and technology, the level of automation in human life is increasing, and daily housework is gradually being replaced by machines. Washing equipment, as a commonly used household appliance, has brought great convenience to people's lives. Washing equipment can be broadly classified into top-loading washing machines and front-loading washing machines based on their washing methods. In current technology, washing machines may leave residual foam after washing. While spraying water can remove foam from clothes, this only involves spraying water into the inner drum or specific areas, resulting in incomplete cleaning.

A spray device includes a spray head disposed between the outer drum rear wall and the inner drum rear wall. The spray head includes multiple first spray holes and multiple second spray holes. The spray direction of the first spray holes is towards the upper part of the inner drum, and the spray water sprayed from the first spray holes generates at least one component velocity tangential to the rotation direction of the inner drum. The spray direction of the second spray holes is towards the lower part of the inner drum, and the spray water sprayed from the second spray holes generates at least one component velocity tangential to the rotation direction of the inner drum. The spray device of this application can improve the cleaning effect, but it cannot completely remove stains and residues on the inner drum, and it also has the problem of incomplete removal of foam on clothes in the inner drum.

[0004] In view of this, the present invention is proposed. Summary of the Invention

The washing equipment can solve the problem of incomplete drum spraying and realize the function of spraying to remove foam by setting a spray control program.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A first aspect of the present invention provides a spray control method for a washing device, comprising:

[0008] S10, Responding to the spray program initiated by the washing equipment;

[0009] S20. Determine that the inner drum of the washing equipment is in the preset initial rotation position;

[0010] S30. Control the spraying device to perform spraying;

[0011] The preset initial rotation position refers to the position where the water outlet of the spray device is directed towards the spray inlet hole on the inner cylinder wall when the inner cylinder is in this position.

[0012] Optionally, a method for determining that the inner drum of the washing machine is in a preset initial rotational position includes:

[0013] Monitor the relative positions of the positioning elements on the inner and outer drums. If the positioning elements on the inner and outer drums are in corresponding positions, then the inner drum of the washing equipment is determined to be in the preset initial rotation position.

[0014] Optionally, if the inner drum of the washing equipment is not in the preset initial rotation position, then the following applies:

[0015] The control motor drives the inner cylinder to rotate at low speed, and monitors the position of the positioning component on the inner cylinder relative to the positioning component on the outer cylinder;

[0016] If the positioning elements on the inner and outer cylinders are in the corresponding positions, the inner cylinder is controlled to stop rotating, and then the spraying device is controlled to perform spraying.

[0017] Optionally, the spraying device can start spraying or, after the first preset spraying time, control the motor to drive the inner cylinder to rotate.

[0018] Preferably, the method of driving the inner cylinder to rotate by a motor includes:

[0019] Control the motor to rotate in both forward and reverse directions at at least one speed;

[0020] Monitor the spraying time of the sprinkler system. If the spraying time reaches the preset time, control the sprinkler system to stop spraying.

[0021] Optionally, the motor can be controlled to drive the inner cylinder to rotate in both directions at stages.

[0022] Preferably, the motor is controlled to rotate at progressively increasing speed, driving the inner cylinder to rotate in both directions.

[0023] Optionally, the spraying device can be controlled to spray for a preset time by rotating the motor in both forward and reverse directions at different speeds.

[0024] In a second aspect, the present invention provides a washing apparatus that applies the spray control method of the washing apparatus described above.

[0025] Furthermore, the spraying device is installed on the outer drum of the washing equipment and sprays water towards the inner drum;

[0027] Furthermore, the washing equipment also includes: positioning components, respectively disposed on the inner drum and the outer drum;

[0028] The monitoring unit monitors the position of the positioning element on the inner cylinder relative to the positioning element on the outer cylinder;

[0029] The control unit controls the motor to drive the inner cylinder to rotate at a low speed based on the monitoring results of the monitoring unit.

[0030] Alternatively, based on the monitoring results of the monitoring unit, the spraying device can be controlled to perform spraying and the motor can be controlled to rotate in both directions at at least one speed.

[0031] Furthermore, the monitoring unit monitors the position of the positioning member on the inner cylinder relative to the positioning member on the outer cylinder. If the positioning member on the inner cylinder and the positioning member on the outer cylinder are in corresponding positions, the control unit controls the spraying device to perform spraying and controls the motor to rotate forward and backward at at least one speed.

[0032] Alternatively, if the monitoring unit detects that the positioning element on the inner cylinder and the positioning element on the outer cylinder are not in corresponding positions, the control unit controls the motor to drive the inner cylinder to rotate at low speed.

[0033] Furthermore, the positioning element includes a sensor disposed on the outer cylinder;

[0034] The sensing unit is located on the inner cylinder;

[0035] The monitoring unit monitors the position of the sensing unit relative to the sensor.

[0036] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0038] 2.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] like Figures 1 to 2 As shown, in a first aspect, the present invention provides a spray control method for a washing device, comprising steps S10 to S30.

[0055] In step S10, the spraying program is initiated in response to the washing equipment.

[0056] In step S20, the inner drum of the washing equipment is determined to be in a preset initial rotation position.

[0057] In step S30, the spraying device is controlled to perform spraying;

[0058] The preset initial rotation position refers to the position where the water outlet of the spray device is directed towards the spray inlet hole on the inner cylinder wall when the inner cylinder is in this position.

[0059] In this embodiment, when the washing equipment receives a command to start the spray program, the system begins to initialize all components required for the spray program, such as the motor, spray device, and water level sensor, ensuring they are in a ready state. The command to start the spray program received by the washing equipment may be selected by the user or may be a spray program that is automatically executed by the washing equipment during program execution.

[0060] Before the spraying program begins, it is necessary to ensure that the inner drum of the washing equipment is in the preset initial rotation position. This preset initial rotation position is designed to direct the water flow from the spray device towards the spray inlet holes on the inner drum wall. This ensures that the spray device can effectively deliver water into the inner drum through these holes, optimizing the spraying effect and avoiding unnecessary energy waste or equipment damage. The relative positions of the devices on the inner and outer drums can be monitored in real time by installing appropriate sensors or other monitoring methods on the washing equipment, ensuring that the inner drum is in the most effective position for the spray device, thereby improving spraying efficiency. After confirming that the inner drum is in the preset initial rotation position, the system will activate the spray device and begin spraying.

[0061] Optionally, a method for determining that the inner drum of the washing machine is in a preset initial rotational position includes:

[0062] Monitor the relative positions of the positioning elements on the inner and outer drums. If the positioning elements on the inner and outer drums are in corresponding positions, then the inner drum of the washing equipment is determined to be in the preset initial rotation position.

[0063] In this embodiment, one or more positioning elements are provided at appropriate positions on the inner cylinder. These positioning elements can be physical protrusions, grooves, magnetic elements, or other marks that can be accurately identified by sensors. Correspondingly, one or more positioning elements or sensors that match the positioning elements on the inner cylinder are also provided on the outer cylinder. The position and type of the positioning elements or sensors on the outer cylinder need to match those on the inner cylinder to ensure that the relative positions of the two can be accurately determined.

[0064] When the washing machine begins its spraying program, the system activates corresponding sensors or monitoring devices to monitor the relative positions of the positioning elements on the inner and outer drums. Specifically, this can be achieved through various methods such as physical contact, photoelectric sensing, and magnetic sensing. If the system detects that the positioning elements on the inner and outer drums are in their preset corresponding positions, indicating that the inner drum has rotated to its preset initial rotation position, the system confirms that the inner drum is accurately positioned at this preset initial rotation position. After confirming that the inner drum is in its initial rotation position, the system continues with the subsequent spraying operation, controlling the spraying device to perform the spraying.

[0065] Optionally, if the inner drum of the washing equipment is not in the preset initial rotation position, then the following applies:

[0066] The control motor drives the inner cylinder to rotate at low speed, and monitors the position of the positioning component on the inner cylinder relative to the positioning component on the outer cylinder;

[0067] If the positioning elements on the inner and outer cylinders are in the corresponding positions, the inner cylinder is controlled to stop rotating, and then the spraying device is controlled to perform spraying.

[0068] In this embodiment, when it is determined that the inner cylinder is not in the preset initial rotation position, the motor is started and the inner cylinder is driven to rotate at low speed to fine-tune the position of the inner cylinder until the inner cylinder is in the preset initial rotation position. This avoids the problem of poor spraying effect or equipment damage caused by directly starting the spraying program in the misaligned position.

[0069] Specifically, positioning elements are installed on both the inner and outer drums. These elements help the system determine whether the inner drum has reached the preset initial rotation position. Sensors or similar devices monitor the position of the positioning elements on the inner drum relative to those on the outer drum in real time. When the positioning elements on both drums are in corresponding positions, it indicates that the inner drum has been adjusted to the preset initial rotation position. At this point, the control motor stops rotating to prevent further movement of the inner drum. After the inner drum position is corrected, the spray device is controlled to spray water evenly onto the clothes, ensuring that the foam on the clothes is evenly sprayed and better removed.

[0070] Optionally, the spraying device can start spraying or, after the first preset spraying time, control the motor to drive the inner cylinder to rotate.

[0071] Preferably, the method of driving the inner cylinder to rotate by a motor includes:

[0072] Control the motor to rotate in both forward and reverse directions at at least one speed;

[0073] Monitor the spraying time of the sprinkler system. If the spraying time reaches the preset spraying time, control the sprinkler system to stop spraying.

[0074] In this embodiment, the inner drum is rotated by a motor simultaneously with the start of the spraying device or after a first preset spraying time. Specifically, the inner drum is rotated by controlling the motor to rotate in both forward and reverse directions at at least one speed, thereby achieving the tumbling of the clothes and uniform spraying. The forward and reverse rotation of the motor not only helps to tumble the clothes, ensuring that all parts of the clothes are fully sprayed and washed, but also improves the water circulation efficiency during the washing process and reduces detergent residue.

[0075] Specifically, the motor speed and stop are adjusted according to a preset program to achieve a specific movement mode of the inner drum; the spray device is activated and the intensity and range of the spray are adjusted to ensure that the clothes are fully sprayed.

[0076] During the spraying process, the spraying time is continuously monitored by a timer or system clock and compared with the preset spraying time. When the preset spraying time is reached, the spraying device is turned off, the spraying operation stops, and the washing equipment is then controlled to execute the subsequent rinsing or dehydration program, with the motor driving the inner drum to rotate at the corresponding speed.

[0077] Optionally, the motor can be controlled to drive the inner cylinder to rotate in both directions at stages.

[0078] Preferably, the motor is controlled to rotate at progressively increasing speed, driving the inner cylinder to rotate in both directions.

[0079] Optionally, the spraying device can be controlled to spray for a preset time by rotating the motor in both forward and reverse directions at different speeds.

[0080] In this embodiment, the motor has multiple preset speed stages, each corresponding to a different speed. These speeds can increase gradually or be specific values ​​set according to the washing program. The spray device operates synchronously with the motor speed. For each speed stage or the entire spray cycle, a corresponding spray time is preset for the spray device. When the spray time reaches the preset value, the spray device will stop spraying for that stage. The preset spray time can be adjusted according to factors such as the washing program, clothing material, degree of soiling, and motor speed to meet different washing needs.

[0081] As a preferred embodiment, the motor is controlled to rotate at progressively increasing speeds, with each stage corresponding to a gradual increase in motor speed. These speed-up stages can be flexibly set according to the needs of the spraying program, for example, starting at low speed and gradually increasing to medium and high speeds. Within each speed-up stage, the motor drives the inner cylinder to rotate at the current speed. The operating state of the spraying device is synchronized with the motor's speed and direction of rotation. When the motor rotates in both directions at a certain speed, the spraying device performs spraying according to the preset spraying mode and time. When the spraying time reaches the preset value, the spraying device is controlled to stop spraying.

[0082] To further illustrate this with a three-stage speed-up rotation example: First, the motor is controlled to rotate forward and backward at a first speed (a relatively low speed) to control the spraying device, which increases the uniformity and coverage of the spray. Simultaneously, the system monitors the spraying time; if the spraying time reaches the first preset spraying time, the motor is accelerated. The system then controls the motor to accelerate to a second speed, which is higher than the first speed. This aims to improve the penetration ability of the sprayed water by increasing the water flow velocity and dynamic changes.

[0083] When the motor speeds up to the second rotational speed, it is controlled to rotate in both directions at this second speed, which is faster than the first speed. This increases the speed or force of the sprayed water, further improving the spraying effect. Simultaneously, the spraying time continues to be monitored, and when the second preset spraying time is reached, the motor speed is increased again. The system controls the motor to speed up to the third rotational speed, which can completely eliminate foam in the inner cylinder through a stronger water flow or more complex dynamic changes.

[0084] When the motor speeds up to the third rotation speed, the control system reverses the motor in both directions at that speed and continues to monitor the spraying time. If the spraying time reaches the third preset spraying time, the control system stops the spraying. After spraying, the washing equipment executes subsequent rinsing or dehydration procedures to complete the entire cleaning process.

[0085] It should be noted that the first, second, and third preset spray times can be set based on experiments or experience, but it is necessary to ensure that the spraying effect is sufficient and not over-cleaning at the current rotation speed.

[0086] like Figures 3 to 5 As shown, in a second aspect, the present invention provides a washing apparatus that applies the spray control method of the washing apparatus described above.

[0087] Furthermore, the spraying device 120 is installed on the outer drum 100 of the washing equipment and sprays towards the inner drum 200;

[0088] Preferably, the spray device 120 is disposed on the bottom wall of the outer cylinder 100 of the washing equipment, and the spray water through hole 210 is disposed on the bottom wall of the inner cylinder 200, and is an arc-shaped structure extending along the circumference of the bottom wall of the inner cylinder 200.

[0089] The radial distance between the spray nozzle of the spray device 120 and the inner cylinder shaft 130 is the same as the radial distance between the spray-type through hole 210 and the inner cylinder shaft 130.

[0090] In this embodiment, the washing equipment integrates the aforementioned spray control method, optimizing the spray effect through intelligent spray control to solve the problem of defoaming clothes in the inner drum 200. The washing equipment in this embodiment can be a washing machine with only a washing function, or it can also have a drying function or other clothing care functions. The washing equipment in this embodiment can be a conventional floor-mounted drum washing machine or a wall-mounted drum washing machine.

[0091] Specifically, the washing equipment mainly consists of two parts: an inner drum 200 and an outer drum 100. The inner drum 200 is rotatably installed inside the outer drum 100. The outer drum 100 includes a rear wall, and the inner drum 200 includes a rear wall. The rear walls of the outer drum 100 and the inner drum 200 are arranged opposite to each other.

[0092] The outer drum 100 not only provides necessary support and protection, but also features a spray device 120, preferably located at the bottom of the outer drum 100, spraying water towards the inner drum 200 to ensure that the spray water reaches the clothes inside the inner drum 200, effectively removing foam. The spray device 120 can employ high-pressure or fine atomizing nozzles to ensure that the water flow evenly covers the surface of the clothes, removing foam. Clothes are placed inside the inner drum 200, and spray water through-holes 210 are provided on the inner drum 200 to facilitate the operation of the spray device 120. These through-holes allow the water sprayed by the spray device 120 to smoothly enter the inner drum 200 and fully contact the clothes. Specifically, the spray water through-holes 210 are designed as an arc-shaped structure extending circumferentially along the bottom wall of the inner drum (200), which not only increases the contact area between the water flow and the clothes, but also makes the water flow more even as it penetrates the clothes, thus improving the washing effect.

[0093] During the spraying process of the washing equipment, the spraying device 120 operates according to a preset spraying control method, spraying at different speeds and spraying times. Spray water is ejected from the spraying device 120 at the bottom of the outer drum 100, enters the inner drum 200 through the spray water passage 210, and fully contacts the clothes, effectively removing foam. As the spraying control method is gradually implemented, the washing equipment can automatically adjust the spraying parameters to achieve the best spraying effect.

[0094] To maximize spraying efficiency, the radial distance between the spray nozzle of the spray device 120 and the inner cylinder shaft 130 is matched with the radial distance between the spray water through hole 210 and the inner cylinder shaft 130, ensuring that the spray water can penetrate the through hole at the optimal angle and speed, reaching the surface of the clothing for deep cleaning.

[0095] Furthermore, the washing equipment is also provided with: positioning components, respectively disposed on the inner drum 200 and the outer drum 100;

[0096] The monitoring unit monitors the position of the positioning element provided on the inner cylinder 200 relative to the positioning element provided on the outer cylinder 100;

[0097] The control unit controls the motor to drive the inner cylinder 200 to rotate at a low speed based on the monitoring results of the monitoring unit.

[0098] Alternatively, based on the monitoring results of the monitoring unit, the spraying device 120 is controlled to perform spraying, and the motor is controlled to rotate in both directions at at least one speed.

[0099] Furthermore, the monitoring unit monitors the position of the positioning member provided on the inner cylinder 200 relative to the positioning member provided on the outer cylinder 100. If the positioning member provided on the inner cylinder 200 and the positioning member provided on the outer cylinder 100 are in corresponding positions, the control unit controls the spraying device 120 to perform spraying and controls the motor to perform forward and reverse rotation at at least one speed.

[0100] Alternatively, if the monitoring unit detects that the positioning element on the inner cylinder 200 and the positioning element on the outer cylinder 100 are not in the corresponding position, the control unit controls the motor to drive the inner cylinder 200 to rotate at a low speed.

[0101] In this embodiment, the washing equipment is also equipped with components such as positioning elements, monitoring units, and control units to achieve accurate control of the position of the inner drum 200 and automation of the spraying program.

[0102] Specifically, the monitoring unit is responsible for real-time monitoring of the position of the positioning element on the inner drum 200 relative to the positioning element on the outer drum 100. This can be achieved through various methods such as physical contact, photoelectric sensing, and magnetic sensing, ensuring that the spray device 120 starts at the correct time and position to improve the spraying effect. The monitoring unit transmits the monitored position information to the control unit so that the control unit can make corresponding control decisions based on this information. The control unit controls the working status of various components of the washing equipment (such as the motor, spray device 120, etc.) based on the monitoring results of the monitoring unit.

[0103] More specifically, when the monitoring unit detects that the positioning element set on the inner cylinder 200 and the positioning element set on the outer cylinder 100 are in corresponding positions, the control unit will control the spraying device 120 to perform spraying and control the motor to rotate forward and backward at at least one speed.

[0104] If the monitoring unit detects that the positioning elements on the inner drum 200 and the outer drum 100 are not in their corresponding positions, the control unit will take corrective measures. Specifically, it will control the motor to drive the inner drum 200 to rotate at a low speed to adjust its position. This low-speed rotation will not damage the clothing and can effectively move the inner drum 200 to the correct position. When the inner drum 200 reaches the preset initial rotation position, the control unit controls the spray device 120 to spray and controls the motor to rotate in both directions at at least one speed.

[0105] Furthermore, the positioning component includes a sensor 110 disposed on the outer cylinder 100;

[0106] The sensing unit 220 is disposed on the inner cylinder 200;

[0107] The monitoring unit monitors the position of the sensing unit 220 relative to the sensor 110.

[0108] In this embodiment, the positioning components include a sensor 110 and a sensing unit 220, which are respectively installed on the outer cylinder 100 and the inner cylinder 200, and work together to determine the position of the inner cylinder 200.

[0109] Specifically, sensor 110 is installed at a specific location on the outer cylinder 100, a location designed to reliably and accurately sense the position of sensing unit 220 on the inner cylinder 200. Sensor 110 is responsible for emitting signals or measuring certain physical quantities (such as magnetic fields, light, distance, etc.), which change with the position of the inner cylinder 200. Sensing unit 220 is installed on the inner cylinder 200, corresponding to sensor 110. The position of sensing unit 220 also needs to be precisely designed to ensure accurate reception of signals from sensor 110 or interaction with it.

[0110] The sensing unit 220 receives signals from the sensor 110 and determines the position of the inner cylinder 200 based on changes in these signals. When the inner cylinder 200 is in a preset initial rotation position, the sensing unit 220 sends a confirmation signal to the control unit.

[0111] More specifically, the sensor 110 and the sensing unit 220 cooperate in some way (such as magnetic field sensing, photoelectric sensing, distance measurement, etc.). When the inner cylinder 200 moves to the preset initial rotation position, the signal emitted by the sensor 110 is accurately received by the sensing unit 220, triggering an acknowledgment signal sent to the control unit. This acknowledgment signal can be transmitted to the control unit via wired or wireless means. After receiving the acknowledgment signal, the control unit will control the motor and the spray device 120 to perform corresponding operations according to the preset program.

[0112] The washing equipment of the present invention achieves efficient and uniform spraying of clothes through an intelligent spray control method and optimized structural design. The ingenious design of the spray device 120 and the spray water through-hole 210 allows the spray water to enter the inner drum 200 more evenly, thereby eliminating additive residues.

[0113] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
