With the development of science and technology, in daily life, external liquid feeding devices (such as water using devices of a washing machine, a dish washer, a water storage tank, a shoe washing machine and the like) are gradually widely applied in daily life, and particularly, the washing machine or the dish washer is taken as an example to specifically describe, and the water using devices of the washing machine or the dish washer and the like are more and more common to clean objects to be washed (such as clothes or tableware) and the like. When the washing machine or the dish washer is used for cleaning the object to be cleaned, a cleaning agent is usually required to be added into the washing machine or the dish washer to ensure the cleaning effect of the object to be cleaned, for example, when the washing machine is used for cleaning the clothes, a liquid detergent, a softener, a bactericide or a fragrance and the like are usually required to be added. Alternatively, in some examples, a dishwasher is typically required to add a detergent to enhance the removal of oil from the dishes when the dishes are washed.
In order to ensure the convenience of adding the cleaning agent, an external cleaning agent adding water device appears in the related technology. The user can once only add external liquid reserve tank or liquid reserve tank with the cleaner in whole, when needs at every turn wash the thing of waiting to wash, add the cleaner to water equipment in the automation. This requires a judgment of the time of addition of the cleaning agent.
In the related art, a flowmeter is usually arranged on a water inlet pipeline of the water using device, water flow in the water inlet pipeline is monitored through the flowmeter, when the water flow in the water inlet pipeline is monitored, an inlet valve of the water using device is proved to be in an open state, and cleaning agent can be added into the water using device at the moment.
However, after a long period of use, the turbine and rotor of the flowmeter are easily stuck, resulting in an inability to accurately determine whether there is water flow in the pipeline.
In other examples, there is also a pressure sensor that monitors the pressure change in the water inlet line to determine whether water flow is present in the water inlet line. However, when the valve on the water inlet line is closed or opened, a sudden change in the flow rate of the water in the water inlet line is liable to form a water hammer effect, which is liable to cause damage to the pressure sensor, resulting in a reduction in the service life of the pressure sensor.

Referring to fig. 5 and 6, in some alternative examples of the embodiment of the present application, a first valve body 113 is provided on the main pipe 110, and the first valve body 113 is used to open or close the main pipe 110. Specifically, when the water equipment is required to be used for cleaning the object to be cleaned, the first valve body 113 can be opened, so that the main pipe 110 is conducted, and water flows into the equipment main body to clean the object to be cleaned; after the cleaning of the object to be cleaned is completed, the first valve 113 may be closed, and no water is supplied into the apparatus body, thereby ensuring dehydration of the cleaned object to be cleaned.
When specifically provided, the first valve body 113 may be any one of a solenoid valve, a pneumatic valve, an electric valve, or a hand valve. It will be appreciated that in the embodiments of the present application, the type of first valve body 113 is illustrated as a few specific examples only and is not limiting of the type of first valve body 113.
In the embodiment of the present application, the first branch pipe 120 may be specifically made of the same material as the main pipe 110. Of course, in some examples, the first branch pipe 120 may also be made of a different material than the main pipe 110. Referring to fig. 5 and 6, in an embodiment of the present application, the first branch pipe 120 may be specifically disposed on the main pipe 110 between the first valve body 113 and the first outlet 112. When specifically arranged, the first branch pipe 120 may be formed integrally with the main pipe 110; in some possible examples, the first branch pipe 120 may also be connected to the main pipe 110 by welding; it will be appreciated that, in other alternative examples of the embodiment of the present application, a tee may be sleeved on the peripheral wall of the main pipe 110, and the first branch pipe 120 is connected to the main pipe 110 through the tee, or a branch pipe of the tee, where one of the branches is not parallel to the main pipe 110, is used as the first branch pipe 120.
Referring to fig. 7 and 8, in the embodiment of the present application, a through hole 114 is provided in a pipe wall of the main pipe 110, and the first branch pipe 120 communicates with the main pipe 110 through the through hole 114. It will be appreciated that the perforations 114 extend through the inner and outer sidewalls of the main tube 110, thereby communicating the interior of the main tube 110 with the first branch tube 120. When specifically provided, the perforations 114 may be formed by drilling, grooving, or boring the pipe wall of the main pipe 110.
Referring to fig. 2, in the embodiment of the present application, the first branch pipe 120 is communicated with the monitoring sensor 200, and when there is a water flow in the main pipe 110, the water flow in the main pipe 110 enters the first branch pipe 120 through the perforation 114, so as to cause disturbance to the monitoring sensor 200, so that the monitoring sensor 200 is convenient to determine whether there is a water flow in the main pipe 110.
In actual use, when the first valve 113 is suddenly opened (for example, when the object to be washed needs to be washed or when water needs to be replenished into the main body of the apparatus), the water hammer effect is easily generated due to the sudden flow of the water flow in the main pipe 110, and a certain impact may be caused to the monitoring sensor 200. For this reason, referring to fig. 8, in the embodiment of the present application, the hole diameter of the perforation 114 is smaller than the inner diameter of the first branch pipe 120.
As some specific examples, the perforations 114 may have a pore size of 1/5 to 1/2 of the inner diameter of the first leg 120. In a specific arrangement, the first branch pipe 120 may be connected to the main pipe 110, and then the perforations 114 may be formed by making holes in the pipe wall of the main pipe 110 from within the first branch pipe 120 in the axial direction of the first branch pipe 120. Of course, in some possible examples, it is also possible to first make an opening in the wall of the main pipe 110 and then connect the first branch pipe 120.
According to the pipe assembly 100 of the embodiment of the present application, by providing the first branch pipe 120 on the main pipe 110, the first branch pipe 120 is provided on the main pipe 110 between the first valve body 113 and the outlet 112; in this way, the monitoring sensor 200, which facilitates monitoring of the state of water flow in the main pipe 110, communicates with the main pipe 110 through the first branch pipe 120, i.e., facilitates the arrangement of the monitoring sensor 200; in this way, when the first valve body 113 is opened, the monitoring sensor 200 can conveniently judge whether the water inlet valve on the main body of the water using apparatus is opened by whether the water in the main pipe 110 flows, thereby conveniently judging the timing of adding the cleaning agent to the water using apparatus. In the embodiment of the present application, a perforation 114 is formed on the pipe wall of the main pipe 110, the perforation 114 communicates the main pipe 110 and the first branch pipe 120, and the aperture of the perforation 114 is set smaller than the inner diameter of the first branch pipe 120; like this, after the rivers in the person in charge 110 get into first branch pipe 120 from perforation 114, because the internal diameter of first branch pipe 120 is greater than the aperture of perforation 114, the rivers velocity of flow can be released and reduced in first branch pipe 120 to can effectively avoid when first valve body 113 closes or opens, the circumstances that the rivers take place the water hammer and cause the impact to monitor sensor 200 in person in charge 110, can effectively protect monitor sensor 200, promote monitor sensor 200's life.
In some alternative examples of embodiments of the present application, with continued reference to fig. 8, the wall of the first branch pipe 120 is provided with a connection portion 121, and the connection portion 121 is used to connect to the monitoring sensor 200; the connection part 121 has a predetermined distance from the outer wall of the main pipe 110.
It will be appreciated that, in a specific arrangement, the connection 121 may be provided on the inner wall of the first branch 120; in some possible examples, the connection 121 may also be provided at an outer wall of the first branch pipe 120. In the drawings of the embodiment of the present application, the connection portion 121 is provided on the inner wall of the first branch pipe 120 as a specific example.
Fig. 9 is a sectional view of a water inlet line in a water service apparatus according to an embodiment of the present application, and fig. 10 is a schematic view of a partially enlarged structure at C in fig. 9.
In some specific examples, the connection 121 may be a thread, a screw thread, or a turnbuckle; that is, the monitoring sensor 200 may be connected to the first branch pipe 120, in particular, by means of a screw connection. In a specific arrangement, referring to fig. 9 and 10, a sealing pad or sealing ring 240 may be disposed at the connection position of the monitoring sensor 200 and the first branch pipe 120, and the connection position of the monitoring sensor 200 and the first branch pipe 120 is sealed by the sealing pad or sealing ring 240, so as to ensure the tightness of the water inlet pipeline 10.
It will also be appreciated that in some possible examples, the monitoring sensor 200 may also be connected to the first manifold 120 via a quick release mechanism.
With continued reference to fig. 8, in the embodiment of the present application, a preset distance is provided between the connection portion 121 and the outer wall of the main pipe 110. That is, when the connection portion 121 is provided on the first branch pipe 120, a portion of the pipe wall of the first branch pipe 120 toward one end of the main pipe 110 is reserved without the connection portion 121.
Thus, as shown in fig. 10, when the monitoring sensor 200 is connected through the connection portion 121, a preset gap is also provided between the end of the monitoring sensor 200 and the outer wall of the main pipe 110, and such a preset gap can provide a buffer space for water flow, so as to effectively reduce the impact of the water hammer on the monitoring sensor 200.
In the embodiment of the application, the connecting part 121 is arranged on the pipe wall of the first branch pipe 120, and a certain interval is kept between the connecting part 121 and the peripheral wall of the main pipe 110, so that when the monitoring sensor 200 is connected to the first branch pipe 120 through the connecting part 121, a buffer space is formed between the monitoring sensor 200 and the outer wall of the main pipe 110, and when the water flow in the main pipe 110 enters the first branch pipe 120 from the perforation 114, the buffer space can be buffered, thereby effectively weakening the water hammer impact effect of the water flow on the monitoring sensor 200 and effectively protecting the monitoring sensor 200.
In another alternative example of embodiment of the present application, referring to fig. 8, the axial direction of the perforation 114 coincides with the axial extension direction of the first branch pipe 120.
When specifically provided, the axial direction of the perforations 114 may be parallel or approximately parallel to the axial direction of the first leg 120, and in some alternative examples, the axial direction of the perforations 114 may be collinear with the axial direction of the first leg 120, that is, the perforations 114 may be coaxial with the first leg 120. Of course, in other alternative examples of the embodiment of the present application, the axial direction of the perforation 114 may be eccentric with respect to the axial direction of the first branch pipe 120, for example, the perforation 114 is offset by a distance in the radial direction of the first branch pipe 120 with reference to the circumferential direction of the first branch pipe 120.
As a specific example of the embodiment of the present application, the monitoring sensor 200 may be specifically a pressure sensor described in the foregoing embodiment of the present application; wherein the sliding pin of the pressure sensor is coaxial with the perforation 114. In some specific examples, the sliding axis of the sliding pin is coaxial with the axis of the perforation 114. In this way, when the water flow in the main pipe 110 flows, the change in the water flow pressure is transmitted from the perforation 114 to the first branch pipe 120, and the water flow can directly act on the sliding pin of the pressure sensor, so that the sensitivity of the pressure sensor to the monitoring of the pressure change in the main pipe 110 can be improved.
In the embodiment of the present application, the axial direction of the perforation 114 is set to be consistent with the axial extending direction of the first branch pipe 120, so that after water in the main pipe 110 enters the first branch pipe 120 from the perforation 114, the water can directly affect the monitoring sensor 200, and cause the fluctuation of the monitoring sensor 200, thereby generating a fluctuation signal, that is, improving the accuracy and sensitivity of the monitoring sensor 200.
In an alternative example of the embodiment of the present application, referring to fig. 5 and 7, the main pipe 110 is further provided with a pressure relief port 115 and a second valve body (not shown in the drawings), the pressure relief port 115 is provided on the main pipe 110 between the first valve body 113 and the outlet 112, and the pressure relief port 115 is used for communicating with a pressure compensating fluid source; the second valve body is used to close or open the relief vent 115.
Specifically, in the embodiment of the present application, the pressure relief port 115 may be disposed in the same or similar manner to the perforation 114 in the previous embodiment of the present application, for example, a hole is formed in the pipe wall of the main pipe 110, or a slot is formed in the pipe wall; of course, in some examples, the pressure relief port 115 may be one of three branches that is not parallel to the main pipe 110.
It will be appreciated that in embodiments of the present application, a second valve body is provided at the relief vent 115 for closing or opening the relief vent 115. When specifically provided, the second valve body may be provided on the main pipe 110. Of course, in some possible examples, the second valve body may also be provided on the branch pipe.
As some alternative examples of embodiments of the present application, the second valve body may be a solenoid valve, an electric valve, a pneumatic valve, or the like.
In the specific setting, the opening and closing of the second valve body may be specifically determined according to the opening and closing of the first valve body 113. It will be appreciated that current washing machines or dishwashers and other water appliances have controllers such as a central processing unit (Central Processing Unit, CPU for short), a micro control unit (Microcontroller Unit, MCU for short), a programmable logic controller (Programmable Logic Controller, PLC for short) and the like. When the first valve body 113 is closed, the first valve body 113 sends a closing signal, and the controller determines that negative pressure is likely to be generated in the main pipe 110 according to the closing signal, and sends a control signal to control the second valve body to be opened.
It will be appreciated that in alternative examples of the embodiment of the present application, when the monitoring sensor 200 detects that the water flow in the main pipe 110 is no longer flowing, for example, the detected flow value of the flowmeter is zero or the flow value is less than or equal to the preset threshold, the controller determines that negative pressure may be generated in the main pipe 110, and sends a control signal to control the second valve body to open. The monitoring sensor 200 is a flowmeter, and the flowmeter may be specifically disposed on the main pipe 110 between the first valve 113 and the inlet 111.
In some alternative examples of embodiments of the application, the pressure relief vent 115 may be provided in the main pipe 110 between the first branch pipe 120 and the outlet 112. In an embodiment of the present application, the pressure relief vent 115 is specifically configured to communicate with a pressure compensating fluid source.
As a specific example of an embodiment of the present application, the pressure compensating fluid may specifically be a gas, for example, in some examples, the pressure compensating fluid may be air. It will be appreciated that in some possible examples, the pressure compensating fluid may also be nitrogen, helium or an inert gas such as xenon, argon, etc. That is, in embodiments of the present application, the pressure compensating fluid source may be the external environment (ambient air is provided as the pressure compensating fluid); in other examples, the pressure compensating fluid source may also be a gas reservoir (providing an inert gas such as nitrogen, helium, etc.), wherein the gas reservoir may be an atmospheric gas reservoir.
In the embodiment of the present application, the pressure relief port 115 and the second valve body are provided on the main pipe 110 between the first valve body 113 and the outlet 112, and the second valve body is used for opening or closing the pressure relief port 115; thus, when the first valve body 113 is closed, the water flow in the main pipe 110 continues to flow under the inertia effect, negative pressure is generated in the main pipe 110, the pressure relief opening 115 is opened by the second valve body, and the fluid in the pressure compensation fluid source can enter the main pipe 110 through the pressure relief opening 115, so that the negative pressure in the main pipe 110 is compensated, the negative pressure in the main pipe 110 can be avoided, and the monitoring sensitivity of the monitoring sensor 200 is influenced.
Additionally, the pressure compensating fluid may be introduced into the main pipe 110, may fill the main pipe 110 at the perforation 114, or may be stored at the perforation 114; when icing occurs in the cold weather main pipe 110, the pressure compensation fluid is stored in the perforation 114, so that the icing is not easy to occur, the damage to the monitoring sensor 200 caused by the icing can be effectively inhibited, and the monitoring sensor 200 is effectively protected.
As a specific example of an embodiment of the present application, referring to fig. 5 and 7, the pressure relief port 115 is located between the first valve body 113 and the first branch pipe 120.
That is, in the embodiment of the present application, the first branch pipe 120 is provided on the main pipe 110 between the relief port 115 and the outlet 112, and the first valve body 113 is provided on the valve body between the relief port 115 and the inlet 111.
In the embodiment of the application, the pressure relief port 115 is arranged between the first valve body 113 and the first branch pipe 120, so that when negative pressure is generated in the main pipe 110, pressure compensation fluid can timely enter the main pipe 110 from the pressure relief port 115 and compensate the negative pressure in the main pipe 110, and the negative pressure formation of the main pipe 110 can be effectively inhibited.
In some alternative examples of embodiments of the application, the distance between the relief vent 115 and the first branch 120 is less than or equal to the distance between the relief vent 115 and the first valve body 113.
Specifically, in the embodiment of the present application, the first valve body 113 and the first branch pipe 120 are first disposed on the main pipe 110, and then the pressure relief opening 115 is offset towards the direction of the first branch pipe 120 when the pressure relief opening 115 is disposed, so as to ensure that the distance between the pressure relief opening 115 and the first branch pipe 120 is smaller than or equal to the distance between the pressure relief opening 115 and the first valve body 113.
In the embodiment of the present application, the distance between the pressure relief port 115 and the first branch pipe 120 is set to be less than or equal to the distance between the pressure relief port 115 and the first valve body 113, that is, the pressure relief port 115 is offset toward the first branch pipe 120 when disposed on the main pipe 110, so that when negative pressure occurs in the main pipe 110, the pressure compensating fluid can be preferentially accumulated in the perforation 114 and the first branch pipe 120, thereby effectively protecting the monitoring sensor 200.
As a specific example of an embodiment of the present application, the second valve body may be a check valve, an outlet of which communicates with the main pipe 110. That is, when a negative pressure is generated in the main pipe 110 (for example, the first valve body 113 is closed, the water flow in the main pipe 110 between the first valve body 113 and the outlet 112 continues to flow under the inertia effect, and the negative pressure is formed in the main pipe 110), the negative pressure acts on the check valve, so that the check valve is opened, and the pressure compensating fluid (for example, air) enters the main pipe 110 through the check valve and the pressure relief port 115, thereby compensating the negative pressure in the main pipe 110, and the air is mainly accumulated in the vicinity of the perforation 114. Damage to the pressure sensor caused by freezing of water flow in the main pipe 110 can be effectively avoided.
In the embodiment of the application, the second valve body is set as the one-way valve, so that when the first valve body 113 is closed, the negative pressure generated in the main pipe 110 can generate suction force on the one-way valve, thereby enabling the one-way valve to be automatically opened, effectively simplifying the control flow of the second valve body, and ensuring the stability and reliability of pressure compensation in the main pipe 110.
It will be appreciated that in other examples of embodiments of the application, as shown with reference to fig. 2, the main pipe 110 may also be provided with a second branch pipe 130, wherein the second branch pipe 130 may in particular be connected to the main pipe 110 between the first branch pipe 120 and the outlet 112. The second manifold 130 may be in communication with the tank 20 for storing cleaning agents described in the previous embodiments of the present application.
