Example one
Fig. 1 is a schematic flow chart of a method for feeding water into a pipeline according to an embodiment of the present invention. Specifically, the pipeline may be a pipeline connected to the water outlet of the water suction device in a washing device, and the washing device may be a milk bottle cleaning machine or a dish washing machine. The embodiment can be applied to the application scene of water inlet of a pipeline connected with a water outlet of a water suction device in washing equipment, and the method can be executed by a water inlet device of the pipeline, wherein the device can be a processor or an MCU (micro control unit) and the like arranged in the washing equipment; in the embodiment of the present application, a water inlet device of a pipeline is taken as an execution main body for explanation, and the method specifically includes the following steps:
the water outlet of the water suction device in the washing equipment is connected with the water outlet pipeline, and after the water body enters the water outlet pipeline, the liquid is transmitted to a target position through the water outlet pipeline. For fluid mechanics reasons, the volute of the water suction device is designed to be in a shape that the volute rotates and the pipe diameter of the volute gradually becomes larger, so that the water outlet of the water suction device is not parallel to the horizontal plane. The water outlet pipeline connected with the water outlet of the water suction device is designed along the opening direction of the volute, and then the diameter of the water outlet pipeline is gradually reduced to be connected with other pipe orifices, so that the water outlet pipeline is in a convex shape to form a cavity. In the water inlet process of the water outlet pipeline, when the water level in the water outlet pipeline gradually rises to the level of the target water outlet of the water outlet pipeline, a certain amount of air can be sealed in the protruding part, namely the cavity, so that an air cavity is formed. Due to the existence of the air cavity, the water outlet pipeline is in a non-liquid-filled state, and the water pressure in the water outlet pipeline is abnormal. To solve the problem, in the present embodiment, a level at which a target water outlet of the water outlet pipe is connected to a port of the chamber is obtained, and the chamber is divided into a first area and a second area based on the level; presetting a region higher than the horizontal height as the first region and the water capacity of the first region as a first capacity; presetting the water capacity of the second area as a second capacity; when a second area lower than the horizontal height in the chamber is filled with water, starting the water absorption device to provide external force for the water body so as to fill the water body into the first area, and extruding air sealed in the first area out after the water body is filled into the first area, so that the water body enters the first area of the chamber; thereby realizing the complete water inlet of the water outlet pipeline.
S110, acquiring the horizontal height of a port, connected with a target water outlet of a water outlet pipeline, of a chamber, and dividing the chamber into a first area and a second area based on the horizontal height; presetting a region higher than the horizontal height as the first region and the water capacity of the first region as a first capacity; presetting the water capacity of the second area as a second capacity; the chamber is formed by connecting a water inlet of the water outlet pipeline and a water outlet of the water absorption device.
In an actual application scene, the water outlet pipeline connected with the water outlet of the water absorption device in the washing equipment can be provided with a plurality of water outlets according to functional requirements and waterway layout, and the water outlet positions of the water outlet pipeline can be a pipeline through position, a pipeline upper position, a pipeline lower position and the like. Since water is denser than air, the air trapped in the duct floats above the interior of the duct. If the water outlet pipeline connected with the water outlet of the water suction device in the washing equipment is provided with a plurality of water outlets, for example, one water outlet arranged above the pipeline and one water outlet arranged at the straight-through position of the pipeline, when the water level in the water outlet pipeline reaches the level of the water outlet arranged above the pipeline after the water enters the water outlet pipeline, if the water continues to enter the water outlet pipeline, the water level in the water outlet pipeline cannot rise, but the water body flows out from the water outlet arranged above the pipeline. Because the air cavity formed by connecting the water outlet pipeline and the water outlet of the water suction device is higher than the water outlet pipeline, the water body cannot enter the area above the horizontal height of the water outlet above the pipeline in the air cavity, and the air sealed in the air cavity cannot be discharged. Therefore, the horizontal height of the water outlet above the pipeline determines the area space of the air cavity which can not enter the water body, and the water outlet above the pipeline in the water outlet pipeline connected with the water outlet of the water suction device in the washing equipment is set as a target water outlet; and if the water outlet pipeline is provided with a plurality of water outlets arranged above the pipeline, selecting one water outlet with the lowest horizontal height as a target water outlet.
Because the horizontal height of the water outlet above the pipeline determines the space of the area where the air cavity can not enter the water body, when the water outlet pipeline enters water, the water inlet of the water outlet pipeline and the water outlet of the water absorption device are connected to form a cavity which is divided into two areas, namely the area of the air cavity which can not enter water and the area which can be filled with water. And obtaining the horizontal height of the target water outlet of the water outlet pipeline and the port connected with the chamber according to the parameters or actual measurement of the water outlet pipeline. The chamber formed by connecting the water inlet of the water outlet pipeline and the water outlet of the water suction device is divided into a first area and a second area based on the obtained horizontal height. Presetting an area higher than the horizontal height as a first area and the water capacity of the first area as a first capacity, and representing an air cavity area incapable of water inflow through the first area; the water capacity of the second area is preset to be a second capacity, and the area in the chamber, which can be filled with water, is represented by the second area. Optionally, the water volume of the first area, i.e. the first volume, may be obtained according to a dimensional parameter or actual measurement of the outlet conduit; the water volume of the second zone, i.e. the second volume, may be obtained from dimensional parameters or actual measurements of the outlet conduit. In detail, since the port of the outlet conduit, at which the target outlet is connected to the chamber, has a port connected to another conduit or component, the height of the port needs to be subtracted after the height of the port of the outlet conduit, at which the target outlet is connected to the chamber, is obtained, so as to obtain the required horizontal height, thereby avoiding the error in dividing the chamber into regions.
Specifically, fig. 2 is a schematic structural diagram of the chamber. The chamber is formed by connecting the water inlet of the water outlet pipeline 21 and the water outlet of the water absorbing device 22, and the chamber is divided into a first area 24 and a second area 25 by connecting the water inlet of the water outlet pipeline and the water outlet of the water absorbing device based on the obtained level of the target water outlet 23. Presetting an area higher than the horizontal height as a first area 24 and the water capacity of the first area as a first capacity, and representing an air cavity area incapable of water inflow through the first area; the water volume of the second region 25 is preset to a second volume by which the region of the chamber that can be filled with water is indicated.
S120, detecting a first water inflow flowing into the water absorption device in real time when the water body flows into the water outlet pipeline through the water inlet of the water absorption device;
after the chamber is divided into a first area and a second area based on the horizontal height of a port where a target water outlet of the water outlet pipeline is connected with the chamber, when a water body flows into the water outlet pipeline through a water inlet of the water absorption device, in order to know the water inlet state in the water outlet pipeline, the first water inflow flowing into the water absorption device can be detected in real time, and therefore the water inflow amount in the chamber is obtained according to the first water inflow. Specifically, the first water inflow flowing into the water absorption device can be calculated according to the water flow of the water inlet of the water absorption device and the actual water inflow time; or a water level detection sensor is preset in the cavity, and the water inlet device of the pipeline receives water level information detected by the water level detection sensor and calculates to obtain a first water inflow flowing into the water absorption device.
S130, if the first water inflow is equal to the second volume, starting the water absorption device to fill a water body into the first area by means of the acting force of the water absorption device;
the area which can be filled with the water body in the preset cavity is the second area, and the water capacity of the second area is the second capacity. When the first water inflow flowing into the water absorption device is detected to be smaller than the second volume, continuing to carry out water inlet operation; when the first water inflow amount flowing into the water absorption device is detected to be equal to or larger than the second capacity, the second area lower than the horizontal height in the cavity is indicated to be filled with water. After the second area in the chamber is filled with water, because the air sealed in the first area higher than the level has resistance, the water body can not enter the first area of the chamber but directly flows out through the target water outlet. The water inlet device of pipeline starts water absorption device when first inflow equals the second capacity and absorbs water, because water absorption device can exert the effort to water at the in-process that absorbs water for the water that erupts from water absorption device's delivery port has certain kinetic energy, and the water that erupts from water absorption device's delivery port can be poured into and is higher than the first region of the level height who obtains. After the water body is poured into the first area, the air enclosed in the first area is extruded out, so that the water body enters the first area of the chamber.
If the acting force applied to the water by the water absorption device in the water absorption process is insufficient, a small amount of bubbles still exist after the water body enters the first area of the chamber and are attached to the inner wall of the first area. In one embodiment, to completely exhaust the air in the first area so that the first area is completely filled with the water, if the first water inflow amount is equal to the second capacity, the water suction device is activated to fill the first area with the water by the action of the water suction device, and the specific process includes steps 11 to 14:
step 11: acquiring angle information of an included angle formed by the inner wall of the first area and a water outlet of the connected water absorption device;
in order to avoid that a small amount of bubbles are still attached to the inner wall of the first area after the water body enters the first area of the chamber, the water body ejected from the water outlet of the water suction device can be poured into the first area along the inner wall of the first area. Therefore, the water ejected from the water outlet of the water absorbing device is required to reach the highest point of the first area, namely the lift of the water absorbing device. And the lift of the water absorption device can be calculated according to the included angle formed by the inner wall of the first area and the water outlet of the water absorption device connected with the first area. In order to calculate the required lift of the water suction device, the water inlet device of the pipeline acquires the angle information of an included angle formed by the inner wall of the first area and the water outlet of the water suction device connected with the inner wall of the first area. Alternatively, the angle information may be calculated from parameter data of the chamber or measured by a worker.
Step 12: determining the target lift of the water absorption device according to the angle information;
and after angle information of an included angle formed by the inner wall of the first area and the water outlet of the connected water absorption device is obtained, calculating the angle information according to the pythagorean theorem and the shape structure of the first area to obtain the target lift of the water absorption device.
In one example, the angle information includes an angle value of the included angle on a horizontal plane; as shown in fig. 2, in combination with the position relationship between the water suction device and the water outlet pipe, the angle information required for calculating the target lift may be an angle value of an included angle formed by the inner wall of the first region and the water outlet of the water suction device connected thereto on a horizontal plane. The specific calculation process of the target lift may be: and acquiring length information of the chamber, and calculating according to the length information and the angle value to obtain the target lift. The calculation formula of the target lift is as follows:
wherein H is the target lift; l is the length information; θ is the angle value; α is an angle error correction coefficient. When the actual working lift of the water absorption device reaches the target lift, the water body ejected from the water outlet of the water absorption device can reach the highest point of the first area, and then the water body is poured into the first area along the inner wall of the first area.
Step 13: obtaining target operation power of the water absorption device according to the target lift;
since the lift of the water absorbing device is related to the target operation power of the water absorbing device, the adjustment of the lift of the water absorbing device can be realized by adjusting the target operation power of the water absorbing device. Therefore, after the target lift of the water absorption device is obtained through calculation, the target running power corresponding to the target lift can be obtained through calculation according to the target lift. The relation between the lift of the water absorption device and the target operation power of the water absorption device is as follows: p (t) QgH/(3.6 η); the above formula, in combination with the target lift H obtained in step 12, obtains a target operating power by the following formula:
wherein P (t) is the target operating power; q is the water flow of the water inlet of the water absorption device; g is a gravity parameter; eta is the efficiency.
Step 14: and if the first water inflow is equal to the second capacity, starting the water absorption device to operate at the target operation power.
After the second area in the chamber is filled with water, because the air sealed in the first area higher than the level has resistance, the water body can not enter the first area of the chamber but directly flows out through the target water outlet. The water inlet device of the pipeline starts the water absorption device to operate at the target operation power when the first water inflow is equal to the second capacity, acting force can be applied to water by the water absorption device in the water absorption process, so that the water body ejected from the water outlet of the water absorption device has certain kinetic energy, when the water absorption device operates at the target operation power, the actual working lift of the water absorption device reaches the target lift, the water body ejected from the water outlet of the water absorption device can reach the highest point of the first area, then the water body is poured into the first area along the inner wall of the first area, and a small amount of bubbles are still attached to the inner wall of the first area after the water body enters the first area of the chamber. The air in the first area is completely discharged, so that the water body completely fills the first area.
S140, acquiring a second water inflow after the water absorption device is started;
in order to realize the water inlet state of the first area in the cavity, the second water inflow after the water suction device is started can be obtained in real time, and therefore the water inflow amount of the water in the first area is obtained according to the second water inflow amount.
In one embodiment, the method for obtaining the second water inflow after the water absorption device is started may be: acquiring the current water absorption rate and the actual starting time of the water absorption device; and calculating to obtain a second water inflow after the water absorption device is started according to the water absorption rate and the actual starting time.
In particular, the water absorption rate of the water absorption device is influenced by the operating power of the water absorption device. After the water absorption device is started, the water absorption rate of the current water absorption device can be calculated by acquiring the current running power of the water absorption device. And acquiring the actual starting time of the water absorption device, and calculating to obtain a second water inflow after the water absorption device is started according to the water absorption rate and the actual starting time.
In another embodiment, a water level detection sensor is preset in the first area of the chamber, the water level sensor is in communication connection with the water inlet device of the pipeline, and the water inlet device of the pipeline receives water level information detected by the water level detection sensor and calculates to obtain a second water inflow after the water absorption device is started.
S150, if the second water inflow is larger than or equal to the first capacity, closing the water absorption device, and recognizing that the gas in the cavity is exhausted.
After the water absorption device is started, when the second water inflow after the water absorption device is started is detected to be smaller than the second capacity, water inflow operation is continued; when the water inlet device of the pipeline detects that the second water inflow after the water suction device is started is larger than or equal to the first capacity corresponding to the first area, the water suction device is closed, and the gas in the cavity is identified to be discharged. When the second water inflow is larger than or equal to the first volume, the first area in the cavity is filled with water, and the air sealed in the cavity is extruded by the water body, so that the water can be completely fed into the water outlet pipeline, and the water pressure in the water outlet pipeline is prevented from being abnormal.
In one embodiment, to achieve complete evacuation of the gas from the chamber, the sum of the first and second inlet volumes may be set equal to the volume of water in the outlet conduit when full (i.e., the chamber is full).
According to the water inlet method of the pipeline provided by the embodiment of the invention, as the water inlet of the water outlet pipeline is connected with the water outlet of the water absorption device to form the cavity, the horizontal height of the port where the target water outlet of the water outlet pipeline is connected with the cavity is obtained, and the cavity is divided into the first area and the second area based on the horizontal height; presetting a region higher than the horizontal height as the first region and the water capacity of the first region as a first capacity; presetting the water capacity of the second area as a second capacity; the area which is sealed with air when the pipeline above the horizontal height in the chamber is filled with water is divided into a first area, and the other area which can be completely filled with water in the chamber is divided into a second area. When water flows into the water outlet pipeline through the water inlet of the water absorption device, detecting a first water inflow flowing into the water absorption device in real time; if the first water inflow is equal to the second capacity, starting the water absorption device to fill the water body into the first area by means of the acting force of the water absorption device; when the first water inflow is equal to the second capacity, the second area lower than the horizontal height in the cavity is filled with water, at the moment, the water absorption device is started to provide external force for the water body so as to fill the water body into the first area, and the air sealed in the first area is squeezed out after the water body is filled into the first area, so that the water body enters the first area of the cavity. Acquiring a second water inflow after the water absorption device is started for detecting whether the first area of the chamber is filled with water or not; and if the second water inflow is greater than or equal to the first capacity, closing the water absorption device and recognizing that the gas in the cavity is exhausted. When the second water inflow is larger than or equal to the first volume, the first area in the chamber is filled with water, and the air sealed in the first area is squeezed out by the water body, so that the water can be completely fed into the water outlet pipeline, and the water pressure in the water outlet pipeline is prevented from being abnormal.
