[0002] A high-pressure washer is a machine that uses high-pressure water flow to clean objects. The high-pressure washers in the prior art usually include a high-pressure water pump and a cleaning gun, and the object to be cleaned is rinsed through the cleaning gun.
[0003] In the prior art, in order to ensure the heat dissipation of the high-pressure water pump, the high-pressure water pump is usually exposed outside, so the noise is relatively large during operation, which does not meet the noise requirements of some countries and regions. However, if a completely covered housing is provided on the outer layer of the high-pressure water pump to prevent noise, it is easy to affect the heat dissipation of the high-pressure water pump, resulting in too high heat inside the housing and affecting the high-pressure cleaning work. Summary of the Utility Model
[0004] The main purpose of the utility model is to overcome the shortcomings of the prior art, and provide a low-noise high-pressure washer that reduces noise and ensures the heat dissipation of the high-pressure water pump through a sound-insulating housing and a cooling device.
[0005] The utility model adopts the following technical solutions:
[0006] A low-noise high-pressure washer includes a high-pressure water pump, a sound-insulating housing, a cooling device and a cleaning gun. The cooling device is arranged on the high-pressure water pump, and the sound-insulating housing covers the outside of the high-pressure water pump so that the cooling device and the high-pressure water pump are located inside the sound-insulating housing. The cooling device includes an upper cooling chamber and a lower cooling chamber. The lower cooling chamber is arranged on the high-pressure water pump, the upper cooling chamber is arranged above the lower cooling chamber, a partition board is arranged between the upper cooling chamber and the lower cooling chamber, the partition board completely separates the upper cooling chamber and the lower cooling chamber, a plurality of parallel and spaced heat dissipation fins are formed on the partition board in an extending manner, and both ends of the heat dissipation fins respectively extend into the upper cooling chamber and the lower cooling chamber. The upper cooling chamber has a water inlet and a water outlet. The water inlet is connected to the water outlet end of the high-pressure water pump, and the water outlet is connected to the cleaning gun.
[0007] Furthermore, a liquid changing door and a connecting door are arranged on the sound-insulating housing. The liquid changing door can be opened or closed and is arranged on one side of the water inlet of the upper cooling chamber, and the connecting door can be opened or closed and is arranged on one side of the water outlet of the upper cooling chamber.
[0008] Furthermore, a drain valve is also arranged on the upper cooling chamber, and the drain valve is arranged on one side of the water inlet.
[0009] Further, a liquid inlet valve and a liquid discharge valve are provided in the lower cooling chamber, and the liquid inlet valve and the liquid discharge valve are located on the same side as the water inlet of the upper cooling chamber.
[0010] Further, a filter screen is provided on one side of the upper cooling chamber close to the water outlet.
[0011] Further, a cleaning window is provided on the upper cooling chamber, and a cover plate is detachably arranged on the cleaning window, and the cleaning window is arranged opposite to the filter screen.
[0012] Further, one side of the water outlet of the upper cooling chamber extends outwards so that the upper cooling chamber forms an L-shaped structure, and correspondingly, the part of the heat dissipation fins located in the upper cooling chamber extends along the upper cooling chamber to form an L-shaped structure in front of the filter screen.
[0013] Further, a support frame is provided below the extended part of the upper cooling chamber.
[0014] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are:
[0015] First, the high-pressure water pump is sound-insulated by the sound-insulating casing to reduce the noise of the high-pressure water pump, and the high-pressure water pump is cooled and dissipated by the cooling device. The coolant is added to the lower cooling chamber, and the high-pressure water pump is dissipated by the coolant. The heat of the coolant is conducted to the upper cooling chamber through the heat dissipation fins. The upper cooling chamber is connected to the water outlet end of the high-pressure water pump and the cleaning gun through the water inlet and the water outlet. During the high-pressure cleaning process, the high-pressure water flow will flow through the heat dissipation fins in the upper cooling chamber, so as to realize heat exchange, effectively achieve the goal of cooling the coolant, and keep the engine within a suitable working temperature range. Through the operation of the heat-conducting fins, the heat dissipation process of the coolant can be accelerated, the overall heat dissipation effect can be improved, and the stable operation of the equipment can be ensured.
[0016] Second, the connection between the cleaning gun and the cooling device is facilitated through the connection door, and the cooling device can be repaired or the coolant in the lower cooling chamber can be replaced through the liquid change door.
[0017] Third, the water in the upper cooling chamber is discharged through the drain valve provided in the upper cooling chamber, avoiding the accumulation of water in the upper cooling chamber after the high-pressure cleaning is completed, reducing the weight of the equipment, facilitating handling and movement. At the same time, it can also prevent the heat-conducting fins from being soaked in water for a long time, thus avoiding affecting the service life of the equipment.
[0018] Fourth, by setting the liquid inlet valve and the liquid discharge valve, the coolant in the lower cooling chamber can be replaced. Through the independent setting of the liquid inlet valve and the liquid discharge valve, new coolant can be injected while discharging the old coolant, maintaining the normal operation of the cooling device.
[0019] Fifthly, filter out impurities in the high-pressure water flow through the filter screen to prevent these impurities from entering the cleaning gun, which may cause the cleaning gun to be blocked, thereby reducing the workload of equipment maintenance. A cleaning window is provided above the filter screen. By regularly cleaning the filter screen, the filtering effect of the filter screen can be ensured, and the reliability and stability of the equipment can be improved.
[0020] Sixthly, the upper chamber extends to form an L-shaped structure to ensure the flow space of the high-pressure water flow in the upper chamber, increase the flow time of the high-pressure water flow in the upper chamber, and the heat dissipation fins located in the upper chamber correspondingly form an L-shaped structure to ensure the contact time and area between the heat dissipation fins and the high-pressure water flow, improve the heat dissipation effect, and ensure the stability of the device through the support frame.

[0026] The following further describes the present invention through specific embodiments.
[0027] Refer to Figures 1 to 4 , a low-noise high-pressure flushing machine of the present invention includes a high-pressure water pump 1, a soundproof housing 2, a cooling device 3 and a cleaning gun 4. The cooling device 3 is arranged on the high-pressure water pump 1, and the soundproof housing 2 covers the outside of the high-pressure water pump 1 so that the cooling device 3 and the high-pressure water pump 1 are located inside the soundproof housing 2.
[0028] The cooling device 3 includes an upper cooling chamber 30 and a lower cooling chamber 31. The lower cooling chamber 31 is disposed on the high-pressure water pump 1, and the upper cooling chamber 30 is arranged above the lower cooling chamber 31. A partition plate 32 is provided between the upper cooling chamber 30 and the lower cooling chamber 31. The partition plate 32 completely separates the upper cooling chamber 30 and the lower cooling chamber 31. A plurality of parallel and spaced-apart heat dissipation fins 33 are formed by extending on the partition plate 32, and both ends of the heat dissipation fins 33 extend into the upper cooling chamber 30 and the lower cooling chamber 31 respectively.
[0029] An inlet 300, an outlet 301, a drain valve 302, a filter screen 303, a cleaning window 304 and a cover plate 305 are arranged in the upper cooling chamber 30. The inlet 300 is connected to the water outlet end of the high-pressure water pump 1, and the outlet 301 is connected to the cleaning gun 4. The drain valve 302 is arranged on one side of the inlet 300, and the outlet 301 is arranged on the side far from the inlet 300. The filter screen 303 is arranged on the side of the upper cooling chamber 30 close to the outlet 301. The cleaning window 304 is disposed opposite to the filter screen 303, and a cover plate 305 is detachably arranged on the cleaning window 304. One side of the outlet 301 of the upper cooling chamber 30 extends outward so that the upper cooling chamber 30 forms an L-shaped structure. Correspondingly, the part of the heat dissipation fins 33 located in the upper cooling chamber 30 extends along the upper cooling chamber 30 to form an L-shaped structure in front of the filter screen 303. The lower cooling chamber 31 is provided with a liquid inlet valve 310 and a liquid discharge valve 311. The liquid inlet valve 310 and the liquid discharge valve 311 are on the same side as the inlet 300 of the upper cooling chamber 30. A support frame 306 is arranged below the extended part of the upper cooling chamber 30.
[0030] A liquid changing door 20 and a connecting door 21 are arranged on the sound insulation housing 2. The liquid changing door 20 is arranged on one side of the inlet 300 of the upper cooling chamber 30 and can be opened or closed. The connecting door 21 is arranged on one side of the outlet 301 of the upper cooling chamber 30 and can be opened or closed.
[0031] Continue to refer to Figures 1 to 4, when the utility model is in use, connect the water inlet 300 of the upper cooling chamber 30 to the water outlet end of the high-pressure water pump 1, open the connecting door 21, connect the cleaning gun 4 to the water outlet 301 of the upper cooling chamber 30, open the liquid changing door 20, inject coolant into the lower cooling chamber 31 through the liquid inlet valve 310, and then close the liquid changing door 20. Start the high-pressure water pump 1. When the high-pressure water pump 1 is running, the coolant in the lower cooling chamber 31 absorbs the heat conducted by the high-pressure water pump 1 to cool and dissipate the heat of the high-pressure water pump 1. The heat in the coolant is conducted by the heat dissipation fins 33 into the upper cooling chamber 30. The high-pressure water flow enters the upper cooling chamber 30 through the water inlet 300, contacts the heat dissipation fins 33 in the upper cooling chamber 30 and conducts heat exchange. After heat exchange, the high-pressure water flow flows into the cleaning gun 4 through the filter screen 303 and is sprayed onto the object to be cleaned.
[0032] Sound insulation is carried out on the high-pressure water pump 1 through the sound insulation housing 2 to reduce the noise during high-pressure cleaning. Through the separated upper cooling chamber 30 and lower cooling chamber 31, the coolant in the lower cooling chamber 31 cools and dissipates the heat of the high-pressure water pump 1. Then, through the heat dissipation fins 33, the high-pressure water flow flowing through the upper cooling chamber 30 dissipates the heat of the coolant, realizing high-speed heat dissipation of the coolant, improving the overall heat dissipation effect of the device. And the high-pressure water flow participating in cooling is the high-pressure water flow used for high-pressure cleaning, without the need to inject other cooling liquids additionally, saving resources. After use, open the liquid changing door 20, and drain the water accumulated in the upper cooling chamber 30 through the drain valve 302 to avoid the heat dissipation fins 33 being soaked in water for a long time, improve the service life of the heat dissipation fins 33, and at the same time reduce the weight of the device, making it convenient to move and transfer. Drain the coolant in the lower cooling chamber 31 through the liquid drain port 311. If the coolant needs to be replaced during high-pressure cleaning, open the liquid changing door 20. While draining the old coolant through the drain valve 311, open the liquid inlet valve 310 to inject new coolant to keep the cooling device 3 running normally.
[0033] The above is only a specific embodiment of the utility model, but the design concept of the utility model is not limited thereto. Any non-substantial modification made to the utility model using this concept shall fall within the scope of infringement of the protection of the utility model.
