Description

Technical Field

[0001] This utility model relates to the field of online cleaning technology for heat exchange equipment, specifically to a pipeline-type rubber ball cleaning device with a bypass ball cleaner, and a condenser including the rubber ball cleaning device. Background Technology

[0002] Some heat exchange equipment (such as the condenser of a central air conditioning system) has multiple heat exchange tubes through which cooling water flows to exchange heat with the heat medium. After a period of operation, sludge, dissolved salts, etc., in the cooling water will deposit on the inner wall of the heat exchange tubes, leading to a decrease in heat exchange efficiency. To address this, a ball cleaning device is used in this field to clean the heat exchange tubes online. This ball cleaning device has an inlet pipe and an outlet pipe, as well as a ball launching and receiving mechanism connected to the inlet and outlet pipes. The ball launching and receiving mechanism is used to launch balls into the inlet pipe. The balls enter the heat exchange tubes with the incoming water. The balls squeeze and scrub the inner wall of the heat exchange tubes, removing deposits. The balls then leave the heat exchange tubes with the outlet water and are collected by the ball launching and receiving device at the outlet pipe. To facilitate recording and counting the number of balls, a ball-dispensing device can be installed on the ball cleaning device.

[0003] Existing ball cleaning devices with ball-spotting devices have several problems. In some devices, the ball-spotting device is installed on the ball-receiving or ball-serving tube. During ball collection / serving, the number of balls passing through the device is recorded. This approach is prone to clogging. Furthermore, when the water volume is high, the balls pass through quickly, leading to inaccurate counting. Conversely, if the water volume is low, the balls cannot be retrieved, creating an irreconcilable conflict between ball collection and counting. To reduce clogging, multiple ball-spotting channels must be designed for simultaneous counting, resulting in numerous pipes, complex installation, and larger equipment size and footprint, thus increasing manufacturing and installation costs. Moreover, due to the high speed and large number of balls passing through instantaneously, even with multiple channels, the risk of clogging remains. Additionally, the speed at which the balls move with the water flow within the device is difficult to control, and the high ball speed results in low counting accuracy. In some rubber ball cleaning devices, the volumetric method is used to measure the height of the rubber balls in a fixed container to estimate the number of rubber balls. This method has poor rubber ball counting accuracy and can only be used for rough estimation. It is not suitable for the central air conditioning rubber ball cleaning industry, where the number of rubber balls is small and the counting accuracy is high.

[0004] To at least overcome the problems in the prior art, this utility model aims to provide a pipeline-type ball cleaning device with a bypass ball cleaner that has a simplified structure and stable operation, and to provide a condenser with improved performance. Utility Model Content

[0005] In a first aspect, this utility model provides a pipeline-type ball cleaning device with a bypass ball-spotting device, comprising: a first ball storage chamber connected to a water outlet pipe via a ball receiving port; a second ball storage chamber located below the first ball storage chamber and connected to a water inlet pipe via a ball-spotting port; a pump for drawing water from the first ball storage chamber or supplying water to the second ball storage chamber; a return water valve located between the first ball storage chamber and the water outlet pipe; a main valve located between the first and second ball storage chambers, which, when opened, transfers balls from the first ball storage chamber to the second ball storage chamber; a ball-spotting device located between the first and second ball storage chambers; and a ball-spotting valve located between the ball-spotting device and the first ball storage chamber, or between the ball-spotting device and the second ball storage chamber, which, when opened, transfers balls from the second ball storage chamber to the first ball storage chamber via the ball-spotting device, for counting the number of balls.

[0006] According to this scheme, the ball cleaning device is equipped with a bypass ball-spotting channel independent of the ball receiving and serving system. When ball-spotting is required, the ball-spotting valve and ball-spotting device on this channel are opened, allowing the balls to be transferred from the second ball storage chamber to the first ball storage chamber via the bypass channel. This directly and smoothly completes the counting of the balls, avoiding the risk of ball blockage that is easily caused when ball-spotting devices are installed on the ball receiving or serving tubes. The ball-spotting bypass channel of this cleaning device can independently spot balls without relying on the ball receiving or serving process of the equipment. It can achieve real-time tracking of the number of balls and the operating status of the equipment. Moreover, the water flow speed that moves the balls in the bypass ball-spotting channel is moderate, which is suitable for the speed of ball-spotting. This avoids ball blockage throughout the equipment, and also avoids inaccurate counting caused by large water volume and excessively fast ball movement speed when ball-spotting is performed simultaneously during serving or receiving. It also avoids the situation where the ball cannot be served or retrieved due to slowing down the water flow for counting. In addition, the ball-balling channel structure in this cleaning device is simplified, with only one bypass for installing the ball-balling valve and ball-balling device. It does not require designing multiple ball-balling channels to achieve ball-balling, making the equipment simple to install and occupying a small area, thereby reducing manufacturing and installation costs.

[0007] In some solutions, when the main valve of the ball cleaning device is closed, the return water valve is open, and the ball-pointing valve is open, the first ball storage chamber is connected to the outlet pipe via the return water valve, and the second ball storage chamber is connected to the inlet pipe. The pressure difference between the inlet pipe and the outlet pipe causes the balls in the second ball storage chamber to enter the first ball storage chamber through the ball-pointing device, and the ball-pointing device counts the number of balls.

[0008] According to this scheme, after opening the main valve to allow the rubber balls to fall into the second ball storage chamber, the main valve is closed, and the ball-pointing valve and return water valve are opened. At this time, the rubber ball cleaning device enters the ball-pointing state. Since the first ball storage chamber is connected to the outlet pipe and the second ball storage chamber is connected to the inlet pipe, the pressure difference between the inlet and outlet pipes causes the rubber balls in the second ball storage chamber to flow with the water through the ball-pointing channel into the first ball storage chamber. When the rubber balls pass through the ball-pointing device on the bypass ball-pointing channel, the ball-pointing device counts the number of rubber balls passing through, thus realizing the function of rubber ball counting. After all the rubber balls have flowed into the first ball storage chamber, the ball-pointing ends. At this time, the ball-pointing valve and return water valve are closed, and the main valve is opened to return the rubber balls from the first ball storage chamber to the second ball storage chamber, entering the preparation state for the next ball-pointing. This ball-pointing process does not depend on the equipment's ball-launching or ball-receiving process, and can realize real-time counting of the number of rubber balls, which is convenient for timely observation of the rubber ball recovery rate and the overall operating status of the equipment. This solution utilizes only the opening of the return water valve to control the water flow that moves the ball in the penalty kick channel. No additional structures are needed to control the water flow during the penalty kick process, simplifying the equipment and reducing manufacturing and installation costs. The return water valve introduces the water flow that moves the ball in the penalty kick channel, ensuring the ball passes through the penalty kick machine at a moderate speed. This avoids ball clogging and inaccurate counting caused by excessively fast ball speed.

[0009] In some designs, the ball cleaning device also includes a drain valve located between the first ball storage chamber and the drain ditch. When the main valve is closed, the return valve is closed, the drain valve is open, and the ball-pointing valve is open, the balls in the second ball storage chamber enter the first ball storage chamber through the ball-pointing device, which counts the number of balls.

[0010] According to this scheme, after opening the main valve to allow the rubber balls to fall into the second ball storage chamber, the main valve is closed, the return water valve remains closed, the ball-pointing valve is opened, and the drain valve is opened to drain water. At this time, the rubber ball cleaning device enters the ball-pointing state. The rubber balls in the second ball storage chamber are carried by the water flow through the ball-pointing channel into the first ball storage chamber. When the rubber balls pass through the ball-pointing device on the bypass ball-pointing channel, the ball-pointing device counts the number of rubber balls passing through, thus realizing the function of rubber ball counting. After all the rubber balls have flowed into the first ball storage chamber, the ball-pointing ends. At this time, the ball-pointing valve and the drain valve are closed, and the main valve is opened to retrieve the rubber balls from the first ball storage chamber to the second ball storage chamber, entering the preparation state for the next ball-pointing. This ball-pointing process does not depend on the equipment's ball-launching or ball-retrieving process, and can realize real-time counting of the number of rubber balls, making it convenient to observe the rubber ball retrieval rate and the overall operating status of the equipment. In this scheme, the flow of water that moves the rubber balls in the ball-pointing channel is achieved only by opening the drain valve, without the need for additional structures to control the water flow during the ball-pointing process. The equipment is simplified, reducing manufacturing and installation costs. By introducing water flow through the drain valve to move the rubber ball in the penalty ball channel, the rubber ball passes through the penalty ball machine at a moderate speed, which avoids both clogging of the rubber ball and inaccurate counting caused by the rubber ball moving too fast.

[0011] In some designs, the ball cleaning device also includes a curved pipe located between the second ball storage chamber and the water inlet pipe; during ball application, the balls in the curved pipe pass through the second ball storage chamber and then through the ball application device into the first ball storage chamber, where the ball application device counts the number of balls.

[0012] According to this design, the opening near the second ball storage chamber of the curved tube is larger, allowing more balls to enter the curved tube through the second ball storage chamber, increasing the ball storage space. During point shooting, this prevents balls from piling up in the second ball storage chamber and becoming blocked due to insufficient water flow. The curvature of the curved tube facilitates the even and gentle movement of the balls with the water flow, allowing them to pass through the point shooting bypass in an orderly manner at a moderate speed. This avoids blockage of the point shooting channel and ensures accurate ball counting. Furthermore, storing the balls in the curved tube through the second ball storage chamber improves serving efficiency. When the device enters the serving state, the balls are positioned below the water flow drop, allowing them to be better propelled out by the water flow, preparing them for a smooth serve. The arrangement of the balls in the curved tube also ensures more even movement, preventing blockages during the serving process.

[0013] In some designs, the ball cleaning device also includes a first pump for drawing water from the first ball storage chamber to the outlet pipe; and a second pump for supplying water from the inlet pipe to the second ball storage chamber.

[0014] According to the scheme, the ball cleaning device adopts a four-pipe structure. The first ball storage chamber is connected to the water outlet pipe through the first and second pipes, and the second ball storage chamber is connected to the water inlet pipe through the third and fourth pipes. Two pumps are used to control the water in the water outlet pipe and the water inlet pipe respectively. The water flow can be controlled according to the different needs of ball launching, retrieval or ball counting, so as to better realize the launching, retrieval or counting of balls, ensure that the operation of the device is more stable and orderly, and avoid the problem of water flow mixing in the system caused by using a single pump.

[0015] In some designs, the pump in the ball cleaning device is used to draw water from the first ball storage chamber to the second ball storage chamber.

[0016] According to the scheme, the ball cleaning device adopts a two-pipe structure. The first ball storage chamber is connected to the outlet pipe, and the second ball storage chamber is connected to the inlet pipe. The first and second ball storage chambers are connected by a pump and a pipeline. When the pump is started, the water in the outlet pipe can pass through the first ball storage chamber into the second ball storage chamber and continue to flow into the inlet pipe. The ball cleaning device has a simplified pipeline and achieves water circulation through the connection of the upper and lower ball storage chambers. The number of connecting pipes is small, and the installation is convenient, which reduces the manufacturing and installation costs accordingly.

[0017] In a second aspect, a ball cleaning device is also provided, comprising a first ball storage chamber connected to a water outlet pipe via a ball receiving port; a second ball storage chamber located below the first ball storage chamber and connected to a water inlet pipe via a ball launching port; a first pump for pumping water from the first ball storage chamber to the water outlet pipe; a second pump for supplying water from the water inlet pipe to the second ball storage chamber; a return water valve located between the first ball storage chamber and the first pump; and a main valve located between the first and second ball storage chambers, which, when opened, allows the balls to be transferred from the first ball storage chamber to the second ball storage chamber.

[0018] According to the scheme, the ball cleaning device adopts a four-pipe structure. The first ball storage chamber is connected to the first pipe and the second pipe, where the first pipe is connected to the first pump. Both the first and second pipes are connected to the outlet pipe, and the first pump can draw water from the first ball storage chamber to the outlet pipe. The second ball storage chamber is connected to the third pipe and the fourth pipe, where the third pipe is connected to the second pump. Both the third and fourth pipes are connected to the inlet pipe, and the second pump can supply water from the inlet pipe to the second ball storage chamber. Using two pumps to control the water in the outlet pipe and the inlet pipe respectively allows for separate control of the water flow according to the different needs of ball emission and recycling, ensuring more stable and orderly operation of the device and avoiding the problem of water mixing in the system caused by using a single pump to control the outlet pipe and the inlet pipe. The opening and closing of the main valve allows the rubber balls to move between the first and second ball storage chambers to adapt to changes in the position of the rubber balls under different operating conditions. Closing the main valve allows the rubber balls flowing out of the outlet pipe to be concentrated in the first ball storage chamber for recycling. Opening the main valve allows the rubber balls to be transferred from the first to the second ball storage chamber in preparation for dispensing. The transfer of the rubber ball position can be achieved with only one main valve, simplifying the equipment and reducing manufacturing costs and operating energy consumption.

[0019] In some designs, the ball cleaning device includes a ball applicator located between a first ball storage chamber and a second ball storage chamber; a ball applicator valve located between the ball applicator and the first ball storage chamber, or between the ball applicator and the second ball storage chamber; and a drain valve located between the first ball storage chamber and a drain ditch. When the main valve is closed, the return valve is closed, the drain valve is open, and the ball applicator valve is open, the balls in the second ball storage chamber pass through the ball applicator into the first ball storage chamber, and the ball applicator counts the number of balls.

[0020] According to this scheme, the ball cleaning device is equipped with a bypass ball-spotting channel independent of the ball-receiving and receiving system. This eliminates the need to rely on the ball-receiving or receiving process, allowing for real-time counting of the balls and facilitating timely observation of the ball recovery rate and the overall operational status of the equipment. When a ball-spotting is needed, the main valve is opened to allow the balls to fall into the second ball storage chamber, then the main valve is closed, the return water valve remains closed, the ball-spotting valve is opened, and the drain valve is opened to drain water. At this point, the ball cleaning device enters the ball-spotting state. The balls in the second ball storage chamber flow with the water through the ball-spotting channel into the first ball storage chamber. As the balls pass through the ball-spotting device on the bypass ball-spotting channel, the device counts the number of balls passing through, thus achieving a ball-counting function. The ball-spotting process is smooth and convenient. Once all the balls have flowed into the first ball storage chamber through the ball-spotting channel, the ball-spotting ends. At this point, the ball-spotting valve and drain valve are closed, and the main valve is opened to return the balls from the first ball storage chamber to the second ball storage chamber, preparing for the next ball-spotting session. The penalty kick process utilizes a drain valve to introduce water flow at a suitable speed into the penalty kick channel, preventing ball clogging throughout the device and avoiding inaccurate ball counting due to difficulty in controlling water volume during simultaneous serve or return. Furthermore, the penalty kick channel structure in this cleaning device is streamlined, with only one bypass for installing the penalty kick valve and penalty kick device. The water flow that moves the ball within the channel is introduced via the drain valve, eliminating the need for multiple penalty kick channels. This simplifies equipment installation, reduces footprint, and consequently lowers manufacturing and installation costs.

[0021] In a third aspect, a condenser is provided that includes the ball cleaning device described in any of the preceding claims.

[0022] According to this scheme, the condenser can achieve real-time online ball counting with high counting accuracy and simplified equipment. It is also convenient to monitor and adjust the equipment status in real time by recording the number of balls. The equipment has a long service life, high reliability, stable operation, and excellent overall performance. Attached Figure Description

Unless otherwise stated, the terminology used herein has its ordinary meaning in the art. The same or corresponding reference numerals in the drawings represent the same or corresponding parts.

[0032] Figure 1 A schematic diagram of the rubber ball cleaning device of this utility model is shown. Figure 1 Referring to Figures 2, 3, 4, and 5, the pipeline-type ball cleaning device with bypass ball cleaner 50 includes: a first ball storage chamber 10, connected to a first pipe 101 and a second pipe 102, wherein the first pipe 101 is connected to a first pump 70, and both the first pipe 101 and the second pipe 102 are connected to the outlet pipe of the condenser (not shown in the figure), and the first pump 70 can draw water from the first ball storage chamber 10 to the outlet pipe; a second ball storage chamber 20, connected to a third pipe 203 and a fourth pipe 204, wherein the third pipe 203 is connected to a second pump 80, and the end of the fourth pipe 204 near the second ball storage chamber 20 is a bend 2041, and both the third pipe 203 and the fourth pipe 204 are connected to the inlet pipe of the condenser (not shown in the figure), the second... Pump 80 can supply water from the inlet pipe to the second ball storage chamber 20; return valve 40, located between the first ball storage chamber 10 and the first pipe 101, can be turned on or off to regulate the pressure in the pipeline; main valve 30, located between the first ball storage chamber 10 and the second ball storage chamber 20, when opened, supplies glue balls from the first ball storage chamber 10 to the second ball storage chamber 20; ball applicator 50, located in a bypass manner between the first ball storage chamber 10 and the second ball storage chamber 20; ball applicator valve 60, located between ball applicator 50 and the first ball storage chamber 10, or between ball applicator 50 and the second ball storage chamber 20, when opened, supplies glue balls from the second ball storage chamber 20 to the first ball storage chamber 10 via ball applicator 50, used for counting the number of glue balls. When a penalty kick is needed, the penalty kick valve 60 is opened, and the control valve that controls the water flow through the penalty kick bypass is opened, so that the rubber balls in the second ball storage chamber 20 are transferred into the first ball storage chamber 10 by the water flow through the penalty kick bypass channel. When the rubber balls pass through the penalty kick device 50 in the penalty kick bypass, the penalty kick device 50 records the number of rubber balls, thereby completing the real-time penalty kick.

[0033] Figure 2 shows a cross-sectional view of the ball cleaning device of this utility model in the state before ball application. In this state, the balls are concentrated in the second ball storage chamber 20 and the bend 2041 connected to the second ball storage chamber 20, waiting for ball application. The main valve 30, the return water valve 40, and the ball application valve 60 are all closed. Other valves and pumps that may be used to control the water flow through the ball application bypass are also not opened. The first ball storage chamber 10 and the second ball storage chamber 20 are not connected, and the ball application system is not working.

[0034] Figure 3 shows a cross-sectional view of the ball cleaning device of this utility model in the ball-pointing state; in conjunction with Figure 6, in the technical solution of introducing water flow into the ball-pointing channel through the return water valve 40, the return water valve 40 is installed between the first ball storage chamber 10 and the outlet pipe. When the return water valve 40 is opened, due to the pressure difference between the outlet pipe and the inlet pipe, the water flow will enter the outlet pipe from the inlet pipe through the second ball storage chamber, the ball-pointing device, the first ball storage chamber, and the return water valve. In the embodiment shown in Figure 3, the return water valve 40 is installed between the first ball storage chamber 10 and the first pipe 101. When ball application is required, the main valve 30 of the system is closed, and the return water valve 40 and the ball application valve 60 are opened. At this time, the equipment enters the ball application state. The opening of the return water valve 40 allows the water to flow from the inlet pipe through the ball application channel to the outlet pipe under the pressure difference between the inlet pipe and the outlet pipe. The rubber balls located in the second ball storage chamber 20 and the bend 2041 enter the first ball storage chamber 10 with the water flow through the ball application channel. When the rubber balls pass through the ball application device 50 on the ball application channel, the ball application device 50 counts the number of rubber balls to achieve real-time ball application.

[0035] The above-described technical solutions are merely specific embodiments, and this utility model is not limited thereto. Referring to Figure 3 in conjunction with Figure 7, the flow of the ball-playing channel can also be achieved by installing a drain valve (not shown in the figure) on the device shown in Figure 3. In the technical solution where water flow is formed through the drain valve, the drain valve is installed between the first ball storage chamber 10 and the drainage ditch. Opening the drain valve can create a water flow that moves the rubber balls in the bypass ball-playing channel. When ball-playing is required, the main valve 30 and the return valve 40 are closed, and the ball-playing valve 60 and the drain valve are opened. At this time, the equipment enters the ball-playing state. Water flows from the inlet pipe into the second ball storage chamber 20 and then into the first ball storage chamber 10 through the bypass ball-playing channel. When the rubber balls located in the second ball storage chamber 20 and the bend 2041 pass through the ball-playing device 50 on the bypass ball-playing channel with the water flow, the ball-playing device 50 counts the number of rubber balls to achieve real-time ball-playing.

[0036] Figure 4 shows a cross-sectional view of the ball cleaning device of this utility model in the ball-ball cleaning end state. In this state, the balls have all flowed from the second ball storage chamber 20 into the first ball storage chamber 10 through the ball-ball cleaning process. At this time, the main valve 30 is kept closed, the ball-ball cleaning valve 60 and the return water valve 40 are closed, and other valves controlling the ball-ball bypass water flow, such as the drain valve in Figure 7, are closed. All the balls are concentrated in the first ball storage chamber 10, and the device is in the ball-ball cleaning end state.

[0037] Figure 5 shows a cross-sectional view of the ball cleaning device of this utility model in the penalty kick preparation state. After the penalty kick is completed, the balls are concentrated in the first ball storage chamber 10. When a serve or a repeat penalty kick is needed, the main valve 30 is opened to allow the balls to enter the second ball storage chamber 20 from the first ball storage chamber 10 to prepare for the serve or the next penalty kick. At this time, the device is in the penalty kick preparation state. After all the balls have entered the second ball storage chamber 20, the main valve 30 is closed, and the device returns to the pre-penalty kick state shown in Figure 2, thereby realizing the penalty kick cycle.

[0038] The basic structure and working principle of each embodiment are described below with reference to the block diagrams. For specific structures, please refer to the preceding sections. Figure 1 Based on the structural deformation shown in Figure 5, these embodiments all fall within the protection scope of this patent.

[0039] Figure 6 shows a schematic diagram of a ball cleaning device that uses a return water valve 40 to control the water flow. In this embodiment, the ball cleaning device includes a first ball storage chamber 10 connected to an outlet pipe; a second ball storage chamber 20 connected to an inlet pipe; a return water valve 40 located between the first ball storage chamber 10 and the outlet pipe; a main valve 30 located between the first ball storage chamber 10 and the second ball storage chamber 20, which, when open, allows the balls to be transferred from the first ball storage chamber 10 to the second ball storage chamber 20; a ball applicator 50 located between the first ball storage chamber 10 and the second ball storage chamber 20, which counts the number of balls as they pass through; and a ball applicator valve 60 located between the ball applicator 50 and the ball storage chamber, which, when open, allows the balls to be transferred from the second ball storage chamber 20 to the first ball storage chamber 10 via the ball applicator 50. Before the ball applicator is applied, the balls are concentrated in the second ball storage chamber 20, and all valves are closed. When a penalty kick is required, open the penalty kick valve 60 and the return water valve 40 to put the equipment into penalty kick mode. The opening of the return water valve 40 allows water to flow from the inlet pipe into the second ball storage chamber 20 under the pressure difference between the inlet and outlet pipes. This water carries the balls from the second ball storage chamber 20 through the penalty kick bypass to the first ball storage chamber 10. As the balls pass through the penalty kick device 50 on the bypass, the device counts the number of balls to complete the penalty kick. After all the balls have entered the first ball storage chamber 10, close the penalty kick valve 60 and the return water valve 40 to end the penalty kick. At this point, the balls are intercepted and concentrated in the first ball storage chamber 10 by the main valve 30, and the equipment is in the penalty kick completed state. If another penalty kick is needed, open the main valve 30 to allow the balls to fall into the second ball storage chamber 20, preparing for the next penalty kick.

[0040] Figure 7 shows a schematic diagram of a ball cleaning device that uses a drain valve to control water flow. In this embodiment, the ball cleaning device includes a first ball storage chamber 10 connected to an outlet pipe; a second ball storage chamber 20 connected to an inlet pipe; a return valve 40 located between the first ball storage chamber 10 and the outlet pipe; a main valve 30 located between the first ball storage chamber 10 and the second ball storage chamber 20, which, when open, allows the balls to be transferred from the first ball storage chamber 10 to the second ball storage chamber 20; a ball applicator 50 located between the first ball storage chamber 10 and the second ball storage chamber 20, which counts the number of balls as they pass through; a ball applicator valve 60 located between the ball applicator 50 and the ball storage chamber, which, when open, allows the balls to be transferred from the second ball storage chamber 20 to the first ball storage chamber 10 via the ball applicator 50; and a drain valve located between the first ball storage chamber 10 and a drainage ditch, which, when open, creates a water flow that moves the balls in a ball applicator bypass. Before the ball applicator is applied, the balls are concentrated in the second ball storage chamber 20, and all valves are closed. When a penalty kick is needed, open the penalty kick valve 60 and the drain valve to put the equipment into penalty kick mode. The opening of the drain valve allows water from the equipment to enter the second ball storage chamber 20 through the inlet pipe, carrying the rubber balls from the second ball storage chamber 20 through the penalty kick bypass to the first ball storage chamber 10. As the rubber balls pass through the penalty kick device 50 on the penalty kick bypass, the device counts the number of rubber balls to complete the penalty kick. After all the rubber balls have entered the first ball storage chamber 10, close the penalty kick valve 60 and the drain valve to end the penalty kick. At this point, the rubber balls are intercepted by the main valve 30 and concentrated in the first ball storage chamber 10. If another penalty kick is needed, open the main valve 30 to allow the rubber balls to fall into the second ball storage chamber 20, preparing for the next penalty kick.

[0041] exist Figure 1 In the embodiment shown in Figure 5, the first ball storage chamber 10 of the ball cleaning device is connected to the outlet pipe via a first pipe 101 and a second pipe 102, and the second ball storage chamber 20 is connected to the inlet pipe via a third pipe 203 and a fourth pipe 204. Two pumps are used to control the water flow between the ball cleaning device and the outlet and inlet pipes, respectively. This type of ball cleaning device is called a "four-pipe system". Further as... Figure 1 As shown in Figure 5, the first ball storage chamber 10 is connected to the first pipe 101 and the second pipe 102. The first pipe 101 is connected to the first pump 70. Both the first pipe 101 and the second pipe 102 are connected to the water outlet pipe. The first pump 70 can pump water from the first ball storage chamber 10 to the water outlet pipe. The second ball storage chamber 20 is connected to the third pipe 203 and the fourth pipe 204. The third pipe 203 is connected to the second pump 80. Both the third pipe 203 and the fourth pipe 204 are connected to the water inlet pipe. The second pump 80 can supply water from the water inlet pipe to the second ball storage chamber 20. By using the first pump 70 and the second pump 80 to control the water flow separately, it is possible to avoid the mixing of water with different temperatures in the water outlet pipe and the water inlet pipe inside the ball cleaning device, which could cause adverse consequences.

[0042] In other embodiments not shown, the first ball storage chamber 10 is connected to the outlet pipe via the second pipe 102, and the second ball storage chamber 20 is connected to the inlet pipe via the fourth pipe 204. The first pipe 101 and the third pipe 203 in the "four-pipe" structure are eliminated. The first ball storage chamber 10 and the second ball storage chamber 20 are connected by a pump and a pipe. This type of ball cleaning device is called a "two-pipe" device. The two-pipe ball cleaning device has only one pump, used to pump water from the first ball storage chamber 10 to the second ball storage chamber 20. When the pump starts, water in the outlet pipe can pass through the first ball storage chamber 10 into the second ball storage chamber 20 to achieve water circulation within the system. Compared to the "four-pipe" device, the "two-pipe" device, by reducing one pump and related pipes, makes the overall structure more compact and reduces costs. Although the specific forms of the "two-pipe" and "four-pipe" devices differ slightly, those skilled in the art can make adaptive changes under the guidance of this patent, and the resulting modified embodiments are all within the scope of protection of this patent. For example, if the first pipe 101 is removed, the return valve 40 can be installed between the first ball storage chamber 10 and the outlet pipe.

[0043] In some embodiments not shown, the condenser includes the aforementioned ball cleaning device. This document describes exemplary embodiments of the present invention in detail with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above-described specific embodiments without departing from the inventive concept, and various combinations can be made to the various technical features and structures proposed in the present invention without exceeding the protection scope of the present invention, which is determined by the appended claims.
