Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a car wash pump heating device. Background Technology
[0002] Existing car wash pumps typically use a motor-driven impeller to pressurize the windshield washer fluid in the reservoir and spray it onto the windshield surface through nozzles to work with the wipers to remove dirt. However, in low-temperature winter conditions, the washer fluid is prone to freezing, causing the pump to malfunction. Even if it doesn't freeze, the low temperature reduces the washer fluid's cleaning power, making it difficult to effectively remove sticky dirt such as oil and insect stains from the glass.
[0003] Some vehicles have heaters installed at the liquid storage tank, but the heating efficiency is low, the power consumption is high, and the liquid will still cool down during transportation, resulting in insufficient temperature of the sprayed liquid and poor cleaning effect.
[0004] Therefore, a washing pump structure that can heat the liquid directly before it is sprayed is needed to improve heating efficiency and cleaning effect, especially suitable for winter and cleaning stubborn stains. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a car wash pump heating device that can directly heat the wash liquid at the inlet, ensuring that the sprayed liquid maintains a high temperature during spraying, thereby improving cleaning ability and preventing icing of pipes and nozzles. To achieve the above objectives, this invention employs the following technical solution:
[0006] This utility model discloses a car wash pump heating device, including a pump body, an inlet, and an outlet. A heating device is installed at the lower end of the pump body. The connection between the heating device and the pump body extends outward and has an outlet. A pump chamber communicating with the outlet is opened at the connection between the heating device and the pump body so that the washing liquid can flow into and out of the outlet. An inlet is opened at the bottom of the heating device. A heating structure for heating the washing liquid is provided between the inlet and the pump chamber. The structure includes a heating chamber communicating with the pump chamber, a ceramic heating element that isolates the liquid and can heat the liquid, a heating element disposed between the ceramic heating element and the outer shell of the heating device, and a temperature controller that controls the heating temperature by setting a temperature threshold. This allows the washing liquid to be better controlled at a suitable temperature, so that the washing liquid will not fail to effectively clean the stains on the windshield due to excessively high or low temperatures. A water inlet channel is provided between the heating chamber and the pump chamber. The temperature controller includes a controller mounted on the housing and a temperature sensor and heater embedded inside. The controller can set a certain threshold to control the temperature inside the heating device. The heater is embedded between the ceramic heating element and the housing and is connected to the aforementioned heating element to heat it and achieve the heating purpose. The device includes a receiver, a conveyor belt, and a sensor head. The temperature sensor extends from the conveyor belt and the sensor head on the side near the ceramic heating element. The sensor head contacts the ceramic heating element, senses the surface temperature of the ceramic heating element, and transmits the information to the receiver through the conveyor belt. When the temperature exceeds or falls below the set threshold, the heater restarts or stops operating to control the temperature within the threshold.
[0007] In the aforementioned car wash pump heating device, a water outlet channel is provided between the pump chamber and the water outlet.
[0008] In the aforementioned car wash pump heating device, an embedded part is provided in the middle of the outer shell of the heating device.
[0009] In the aforementioned car wash pump heating device, in order to prevent the heating device housing from being affected by the internal heating temperature, a heat insulation component is installed between the ceramic heating element and the housing. The heat insulation component is tightly fitted to the side near the housing and extends to the upper and lower ends to ensure that most of the heat energy is in contact with the ceramic heating element, achieving a rapid heating effect.
[0010] In the aforementioned car wash pump heating device, a limiting part is provided inside the heating device, and the ceramic heating element is tightly attached to the limiting part.
[0011] Compared with existing technologies, the car wash pump provided by this utility model has the following beneficial effects: the heating device is installed at the upper end of the water inlet, directly heating the water inlet, reducing heat loss and improving heating efficiency; the wash liquid treated by the heating device reaches a certain temperature, which can effectively dissolve adhesive dirt such as oil stains and insect stains, and improve cleaning performance in winter; the heating device is equipped with a thermostat, which will maintain the wash pump at a suitable temperature under normal circumstances, and prevent the pipeline and nozzle from freezing in low-temperature conditions in winter; the heating device is integrated with the pump body, which does not affect the original installation space; and overheating and excessive energy consumption are avoided through temperature sensing and automatic control.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the present invention. However, the described embodiments are only a part of the embodiments of the present invention.
[0019] In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0020] like Figure 1 As shown, the system includes a pump body 1, an inlet 2, and an outlet 3. A heating device 4 is installed at the lower end of the pump body 1. The inlet 2 is located at the bottom, and the outlet 3 is located on a block extending from the top side of the heating device 4. Figure 2 As shown, a pump chamber 41 is provided between the pump body 1 and the heating device 4, and a water outlet 3 is provided with a water outlet channel 31 that communicates with the pump chamber 41. A heating chamber 42 capable of heating the washing liquid is provided between the pump chamber 41 and the water inlet 2, and a water inlet channel 43 for the heated washing liquid to flow through is provided at the upper part of the heating chamber 42.
[0021] The heating device 4 has a heating structure in its center that heats the washing liquid. This heating structure is a ring-shaped structure surrounding the heating chamber 42, featuring a ceramic heating element 7 that isolates the liquid while simultaneously heating it. This element both isolates the washing liquid within the heating chamber 42 and provides heating. Multiple heating elements 6 are installed between the ceramic heating element 7 and the outer casing of the heating device 4, along with a thermostat 5 that controls the heating temperature by setting a temperature threshold. This allows for better control of the washing liquid at a suitable temperature, preventing it from being too hot or too cold to effectively clean stains on the windshield. Figure 2 and Figure 4 As shown, the heating device 4 has an embedded part 44 on the outer side of the middle part, and the temperature controller 5 is embedded in the heating structure. The temperature controller 5 is divided into a controller 51 installed on the outer side, a heater 52 and a temperature sensor 53 embedded on the inner side. The temperature sensor 53 is located at the bottom of the heater 52. Multiple heating elements 6 are connected to both sides of the heater 52. The heater 52 heats the heating elements 6 to raise their temperature.
[0022] like Figure 3 As shown, the heating structure includes a ceramic heating element 7 for fixing the heating element. When the heating device 4 operates, its internal heating structure generates a large amount of heat, which is conducted to the outer casing, causing the entire pump body 1 to heat up and potentially damaging the washing pump. Figure 2 As shown, inside the heating structure, that is, between the ceramic heating element 7 and the outer shell, a heat insulation element 8 is installed on the inner wall near the outer shell and extends to the upper and lower ends. This prevents the internal heating energy from being trapped inside and allows the ceramic heating element 7 to heat up faster, thus improving heating efficiency.
[0023] like Figure 5 As shown, a receiver, a conveyor belt, and a sensor head are provided on the temperature sensor. The conveyor belt and the sensor head extend to the side close to the ceramic heating element. The sensor head contacts the ceramic heating element and senses the temperature of the surface of the ceramic heating element. The information is then transmitted from the sensor head to the receiver via the conveyor belt, so that the receiver controls the heater to heat up or stop heating.
[0024] The working principle of this utility model is as follows: When the car wash pump of this utility model is working, the impeller driven by the motor rotates at high speed, forming a negative pressure to draw the washing liquid in the storage tank into the pump chamber 41 through the inlet 2. The heating device 4, located at the inlet 2, is powered on in advance to preheat the heating element 6 and raise the temperature inside the heating device 4. The temperature is transferred to the ceramic heating plate 7 through the heat insulation element 8 installed on the side wall, so that it quickly heats up to the set temperature threshold, thereby heating the washing liquid to the set temperature. The washing liquid is heated before entering the pump chamber 41, which can effectively reduce the viscosity of the liquid under low temperature conditions, prevent ice formation or poor flow in the suction pipe, ensure the normal liquid suction efficiency of the pump, and dissolve the attached frost, snow or oil stains more quickly, improving the cleaning effect and defrosting speed. When the temperature sensor 53 detects that the washing liquid temperature is lower than the preset threshold, the control circuit automatically supplies power to the heating element 6 to ensure the automation and energy saving of the heating process.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
[0026] However, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
