Description

Technical Field

[0001] This utility model relates to the field of self-service car wash machines, and more specifically, to a self-service car wash machine antifreeze pipeline structure. Background Technology

[0002] With the increasing number of cars, the demand for car washes has also increased, leading to the rapid development of the car wash industry. Self-service car wash machines have become increasingly sophisticated and widely used. However, due to the inherent structure of current self-service car wash machines, water in the hoses and nozzles often cannot be completely drained after use. Furthermore, since self-service car wash machines are generally located outdoors, in winter when temperatures are low or the ambient temperature drops below zero, the water remaining in the hoses or nozzles can freeze, causing blockages or even breakage, ultimately preventing the machine from functioning properly. Therefore, to ensure that self-service car wash machines can still operate normally in winter or when the ambient temperature is below zero, manual antifreeze measures must be implemented before and after use. This process is complex and has high maintenance costs. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a self-service car wash machine antifreeze pipe structure, including a water inlet tank, an antifreeze box, and a drive box arranged sequentially from top to bottom. A water pump is installed inside the water inlet tank. An antifreeze pipe with a wavy bend is installed inside the antifreeze box. Several heating pipes are installed on the rear side of the antifreeze pipe. One end of the antifreeze pipe is connected to a three-way valve, and the other end extends through the antifreeze box to the outside of the antifreeze box. A first water inlet pipe is installed at the output end of the water pump and extends into the antifreeze box. The three ports of the three-way valve are respectively connected to the antifreeze pipe, the first water inlet pipe, and the exhaust fan. An air inlet pipe is installed on the outer wall of the antifreeze box.

[0006] In a preferred embodiment, the two ends of the inner shaft of the upper roller are connected to an upwardly extending upper connecting rod, and the two ends of the inner shaft of the lower roller are connected to a downwardly extending lower connecting rod, with a connecting plate installed at the bottom end of the lower connecting rod.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] like Figure 1-4The self-service car wash machine antifreeze piping structure shown includes a water inlet tank, an antifreeze box, and a drive box arranged sequentially from top to bottom. A water pump is installed inside the water inlet tank. An antifreeze pipe with a wavy bend is installed inside the antifreeze box. Several heating pipes are installed on the rear side of the antifreeze pipe. One end of the antifreeze pipe is connected to a three-way valve, and the other end extends through the antifreeze box to the outside of the antifreeze box. A first water inlet pipe is installed at the output end of the water pump and extends into the antifreeze box. The three ports of the three-way valve are respectively connected to the antifreeze pipe, the first water inlet pipe, and the exhaust fan. An air inlet pipe is installed on the outer wall of the antifreeze box.

[0019] Furthermore, the water pump input end is connected to a second water inlet pipe, which extends through the water inlet tank to the outside of the water inlet tank, and the antifreeze pipe extends to the outside of the antifreeze tank and is connected to an outlet pipe.

[0020] Based on the above, during normal car washing operations, the interface connecting the three-way valve and the exhaust fan is closed, while the remaining two interfaces are connected. The water pump operates, drawing the cleaning water from the second inlet pipe into the pump, and then delivering it through the first inlet pipe and the three-way valve to the antifreeze pipe. Finally, it is output from the outlet pipe, which can be connected to equipment such as a water gun to pressurize and spray the cleaning water.

[0021] After the car wash is completed, the interface connecting the three-way valve to the first water inlet pipe is closed, while the remaining two interfaces are connected. At the same time, the heating tube inside the antifreeze box is activated, heating the air inside the antifreeze box. Then, the exhaust fan is activated, generating negative pressure to draw the heated air inside the antifreeze box into the antifreeze tube. This causes the hot air to flow continuously through the antifreeze tube, forming a high-speed hot airflow that washes and evaporates any residual water stains on the inner wall of the pipe, and heats and dries any remaining water stains inside the antifreeze tube.

[0022] The air inlet duct is equipped with a dustproof screen, and a temperature sensor and a humidity sensor are installed at the bottom of the antifreeze box.

[0023] Based on the above, when drying the water stains remaining inside the antifreeze tube, the exhaust fan will draw out the air inside the antifreeze box, and then the outside air will enter the antifreeze box from the air inlet pipe for air pressure compensation. The dust filter reduces the entry of dust and debris into the antifreeze box.

[0024] An upper roller is inserted into the bend of the antifreeze tube near the top of the antifreeze box, and a lower roller is inserted into the bend of the antifreeze tube near the bottom of the antifreeze box. Both ends of the upper and lower rollers are equipped with baffles to limit the movement of the antifreeze tube. A rotating shaft is inserted inside the upper and lower rollers.

[0025] The two ends of the inner rotating shaft of the upper roller are connected to an upwardly extending upper connecting rod, and the two ends of the inner rotating shaft of the lower roller are connected to a downwardly extending lower connecting rod. A connecting plate is installed at the bottom end of the lower connecting rod.

[0026] The drive box is equipped with a servo push rod, and the output shaft of the servo push rod passes through the antifreeze box and is fixedly connected to the connecting plate.

[0027] Based on the above, the antifreeze pipe is wavy and bent inside the antifreeze box. When the antifreeze pipe is straightened, the length of the part exposed outside the antifreeze box can be increased, which facilitates car washing operations.

[0028] Furthermore, when it is necessary to straighten the antifreeze tube and pull it out of the antifreeze box, the servo motor is controlled to drive the connecting plate to move upward, causing the lower connecting rod and lower roller on the connecting plate to move upward. At this time, the user pulls the antifreeze tube outward. During this process, the bend of the antifreeze tube will drive the lower roller and upper roller to rotate outside the rotating shaft, realizing the orderly outward movement of the antifreeze tube. When it is necessary to pull the external antifreeze tube back into the antifreeze box, the servo motor is controlled to drive the connecting plate to move downward, pulling the lower roller and lower connecting rod to move downward, pulling the bend of the antifreeze tube downward, thereby retracting the antifreeze tube into the antifreeze box.

[0029] The above structure facilitates the storage and retraction of the antifreeze tube, effectively extending its length and preventing it from being exposed when idle, thus improving its antifreeze effect. The baffle plate restricts the lateral displacement of the antifreeze tube during the extension and retraction process.

[0030] Based on the above, after the car wash operation is completed, the antifreeze pipe is first left outside the antifreeze box. Then, the three-way valve is closed between the pipe and the first water inlet pipe, while the remaining two ports are connected. This allows the exhaust fan to operate, continuously injecting air into the antifreeze pipe and generating a high-speed airflow inside. This airflow is sufficient to draw the remaining water stains to the outside, preventing excessive water stains from remaining inside the antifreeze pipe. After the antifreeze pipe is returned to the antifreeze box, excessive water stains will not accumulate at its downward bend, facilitating subsequent heating and drying operations.

[0031] After initially cleaning the water stains inside the antifreeze pipe, repeat the heating and drying process described above to dry the remaining water stains inside the antifreeze pipe. This will prevent the antifreeze pipe from freezing, becoming clogged, or cracking when the outdoor temperature is below zero in winter.

[0032] A control box is fixed to the top of the antifreeze box on one side of the water inlet tank. The three-way valve is a solenoid valve that can be electrically controlled. The exhaust fan, water pump and servo push rod in the equipment are all connected to corresponding controllers. The controllers are connected to the control center inside the control box. The entire equipment can be driven and used by setting the corresponding remote control.

[0033] Furthermore, the temperature and humidity sensors are connected to the control center inside the control box, uploading the temperature and humidity information obtained from inside the freezer. When the outdoor temperature is too low in winter, the heating element can be controlled to work, raising the temperature inside the freezer and preventing the pipes from freezing, blocking, or cracking.

[0034] The controller and device are connected via a bus (such as CAN, RS485) or pulse signal (PWM) to convert control commands into actions of the water pump or push rod. The selection of the controller and servo driver and the closed-loop control logic (such as PID algorithm) are conventional technical means in this field, and the specific programming code does not need to be described in detail.

[0035] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
