DETAILED DESCRIPTION

In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The present invention provides a water outlet control method for an intelligent shower, which is used to solve the problem in the prior art that the water outlet mode of the shower is complicated and difficult to adjust, thus affecting the shower experience of the user.

Please refer to FIG. 1 , which is a first flow chart of a water outlet control method of an intelligent shower provided by an embodiment of the present invention.

S100, obtaining shower installation parameters, establishing a shower coordinate system, and obtaining shower coordinates in the shower coordinate system according to the shower installation parameters; obtaining shower coverage area coordinates and water outlet coordinates corresponding to each shower outlet scheme according to the shower coordinates;

It should be noted that the spatial coordinate system is established based on the shower space. Generally, a shower space is divided in a bathroom with dry and wet separation in a house toilet, or it can be a space established with the ground drainage area as the bottom surface. Any point in the space is selected as the origin of the spatial coordinate system to establish the spatial coordinate system; in this embodiment, the coordinates of the center point of the overhead shower can be set as the shower coordinates;

When installing a shower, the distance of the shower relative to the wall or the ground, as well as the specifications and dimensions of the shower can be determined. For example, an overhead showerhead that is generally located directly above the user's head will be fixed to the wall through a bracket to form a parallel position with the ground, or fixed to the ceiling. The position of the overhead showerhead is fixed, so the corresponding showerhead coordinates can be obtained in the spatial coordinate system;

There will be multiple water outlets arranged on the shower head. The shower head can control the water to flow out from different water outlets by changing the flow path of water in the shower head. In order to achieve a better shower effect, the overhead shower head generally chooses to combine multiple water outlets to discharge water at the same time to form a set of water outlet solutions. The water outlet of each water outlet solution is fixed and cannot be changed. For example, the circular hollow water outlet solution for washing the face, the centrally-controlled pressurized massage water outlet solution, the overhead rainforest water outlet solution or the overhead waterfall water outlet solution. Each solution is to form different water flow shapes or forms by combining water outlets of different shapes and positions. Different water outlet solutions can achieve different shower effects to meet user needs. After the coordinates of the center point of the shower head are determined, the coordinates of the water outlet and the coordinates corresponding to the shower coverage area enclosed by the water outlets of each water outlet solution can be calculated according to the specifications and dimensions in the installation parameters and the distribution of the water outlets on the overhead shower head.

In an overhead shower, the water flow path is a vertical route from top to bottom, and the water flow speed is only affected by water pressure and gravity; in this solution, because the overhead water flow is mainly affected by gravity and regardless of the water outlet pressure, the water flow path is vertical, so there is no need to consider the problem of changing the shower coverage area by increasing the water outlet to change the water pressure; the different water outlet solutions of the overhead shower correspond to a vertical space, which will be filled with water along the vertical direction of the water outlet, and the user's body part in the space can be showered by the water.

S200, identifying the position and outline of the current user to obtain user coordinates; combining various water outlet solutions to obtain shower coverage overlap area coordinates of various combinations, identifying the coordinates of the overlapping areas of each shower coverage overlap area coordinate and the user coordinates, and obtaining the number of water outlets in the overlapping area;

It should be noted that an infrared sensor can be provided on the shower to detect and identify the user's position and outline, or machine vision can be used based on image processing to identify the user's outline. The user's position can be effectively identified according to the installation position of the sensor or camera, and the outline can be further accurately corrected in combination with the body data pre-uploaded by the user in the system. The user's position and outline can be combined to obtain the user's coordinates. In this embodiment, the user's showering situation when the overhead shower discharges water vertically is considered, so only the coordinates of the user on the horizontal plane need to be obtained to compare with the horizontal coordinates of the shower coverage area;

After combining the various water outlet schemes, the shower coverage area can be overlapped, and the water outlets of multiple schemes can discharge water at the same time. When the number of water outlet schemes is n, there are a total of combinations; the shower coverage area coordinates of each combination can be calculated to obtain the shower coverage superposition area coordinates of the combination, and the shower coverage superposition area coordinates can be compared with the user coordinates to identify the overlap area coordinates of the intersection. The overlap area is the area where the user's body is where the shower is outlet. According to the overlap area coordinates and the water outlet coordinates, the number of water outlets that actually act on the user's body for showering can be obtained.

S300, based on the shower strategy preset by the user, according to the number of water outlets in the overlapping area, the number of water outlets in the shower coverage overlapping area and the area of the shower coverage overlapping area, the best shower water outlet solution combination is selected, and the shower water outlet is controlled.

It should be noted that a variety of shower strategies are preset in the smart shower, and users can choose according to their own needs or preferences. In this embodiment, the shower strategy includes an economic strategy and a comfort strategy. The water flow of the shower is fixed, and only the water outlet changes under different water outlet schemes. The purpose of the economic strategy is to minimize the user's shower time with the highest shower water utilization rate while considering the user's water demand for showering as a fixed value. At this time, the total water consumption is also the least. The economic strategy considers the ratio of the number of water outlets in the shower coverage overlapping area to the number of water outlets in the overlapping area. The larger the ratio, the greater the water flow per unit time that showers on the user, and the faster the user can finish showering. Select the combination of water outlet solutions with the largest ratio; under the comfort strategy, in order to ensure that the user's body is covered as evenly as possible, the cross-sectional area of the shower coverage superposition area is divided by the number of water outlets in the superposition area to obtain the shower coverage density, that is, under the same coverage area, the more water outlets there are, the more uniform the shower effect can be brought to the user. Under the comfort strategy, select the combination of water outlet solutions with the largest shower coverage density; in the aforementioned step S200, the user's position and contour are obtained in real time, and the water outlet solution can be changed as the user's position changes. The user can further control it according to the shower needs. If only a single water outlet solution is required, the water outlet solution can be fixed according to the user's needs.

After obtaining the best shower water outlet solution that best meets user needs, the smart shower will change the water flow path so that the water flows out from the corresponding outlet. Users can also adjust their shower strategies during the shower process, through voice interaction with the built-in microcomputer of the smart shower or by using smart buttons.

In this embodiment, a coordinate system is established to calculate the coordinates of the water outlet coverage area of each water outlet scheme of the shower, and the user's location outline is identified in real time, and the combinations of all water outlet schemes are traversed. The overlapping area of the area of the water outlet scheme combination and the user's outline area, as well as the water outlet situation in the area are calculated. Based on the user's shower strategy, a shower scheme combination that meets the user's needs is selected, the shower outlet is adjusted, the user's shower experience is enhanced, and a comfortable, stress-relieving, and fatigue-relieving bathing space is created for the user.

The above is a detailed description of the first embodiment of a water outlet control method for a smart shower provided by the present application. The following is a detailed description of the second embodiment of a water outlet control method for a smart shower provided by the present application.

In this embodiment, a water outlet control method for a smart shower is further provided. After the aforementioned step S300, the method further includes: obtaining the user outline area according to the user outline, calculating the ratio of the current coverage overlap area area to the user outline area, and when the ratio is less than a preset threshold, identifying the offset direction of the user relative to the shower, and sending a tilt instruction to the shower according to the offset direction. It should be noted that the user's position may deviate from the overhead shower when taking a shower, so the smart shower can adjust the water outlet direction by identifying the user's position to increase the coverage overlap area; by calculating the ratio of the current coverage overlap area area to the user's outline area, the proportion of the area covered by the shower on the user's body can be obtained. When the ratio is less than the preset threshold, it means that the proportion of the user's body covered is small, and the direction of the universal axis of the shower can be adjusted to make the shower rotate from horizontal to the ground to tilt toward the user. The user's offset direction can be obtained according to the vector between the user coordinates and the shower coordinates. The universal axis can be driven by a motor, and the tilt angle of each rotation of the shower can be a preset value; after the shower tilts to change the water outlet direction, the aforementioned steps are performed again.

Furthermore, in the aforementioned step S100, the shower installation parameters also include a tilt angle, and an offset distance is obtained according to a preset tilt angle and offset relationship model, and the shower coverage area coordinates are corrected by the offset distance.

It should be noted that the rotation angle of the overhead shower is limited, and it generally rotates only within a small acute angle range. Therefore, this embodiment does not consider the change in coverage area caused by the parabolic deviation or fall of the water flow, but only considers the movement of the shower coverage area. The relationship model between the tilt angle and the offset can be a tangent model, that is, the tangent value of the tilt angle is equal to the ratio of the offset distance to the preset height difference; the preset height difference can be the difference between the ceiling height where the shower is installed and the preset user shower height, or the user height is obtained according to the infrared sensor ranging. After calculating the offset distance, the shower coverage area coordinates and the water outlet coordinates in the aforementioned step S100 are added with the offset distance to complete the correction. The corrected coordinates are the coverage area after the shower is rotated. After the aforementioned steps are performed to rotate and tilt the shower, the offset calculation of this scheme can be performed again.

The above is a detailed description of a water outlet control method of an intelligent shower provided in the first aspect of the present application. The following is a detailed description of an embodiment of a water outlet control system of an intelligent shower provided in the second aspect of the present application.
