[0032] like Figures 1 to 5 As shown in the embodiment of this application, a washer heating device is used to heat the washing liquid inside the washer reservoir 1 in a vehicle. The heating device includes a heater 2 and a first temperature sensor 3. The heater 2 includes a heating element 21 and a first power connector 22. One side of the heating element 21 extends into the washer reservoir 1 and is located in the washing liquid inside the washer reservoir 1. The first power connector 22 passes through the side wall of the washer reservoir 1 for connection to a power source and is sealed to the side wall of the washer reservoir 1. One end of the first temperature sensor 3 extends into the washer reservoir 1, and the other end is provided with a second power connector. The first power connector 22 includes a first positive contact piece 221 and a first negative contact piece 222. The second power connector includes a second positive contact piece 31. The second power connector and the first power connector 22 share the first negative contact piece 222. The first positive contact piece 221, the second positive contact piece 31, and the first negative contact piece 222 are electrically connected to the power source.

[0033] Combined with the above embodiments, the washing pot 1 is installed on a vehicle, and washing liquid can be input into the washing pot 1 for spraying the washing liquid onto the front windshield or the rear windshield. The heating device is installed on the washing pot 1 for heating the washing liquid inside the washing pot 1. The heater 2 of the heating device includes a heating element 21 and a first power connection plug 22. The heating element 21 is integrally connected to the first power connection plug 22, and the heating element 21 also extends into the interior of the washing pot 1. The first power connection plug 22 is used to connect to the power source on the vehicle so as to heat the washing liquid through the heating element 21.

[0034] The first temperature sensor 3 is installed on the first power connection plug 22 and is arranged inside the washing pot 1 together with the heating element. Moreover, the first temperature sensor 3 shares a negative electrode with the first power connection plug 22, which improves the integration of the overall structure, simplifies the complexity of power connection, and at the same time reduces the occupied space of the heating device.

[0035] For the washer heating device in the embodiment of the present application, the heating device further includes a sealing gasket 4. An installation hole matching the shape and external dimensions of the first power connection plug 22 is formed on the side wall of the washing pot 1. The sealing gasket 4 is arranged in the installation hole and is in sealing cooperation with the first power connection plug 22.

[0036] Combined with the above embodiments, the shape and size of the installation hole match the first power connection plug 22. When the cross-section of the first power connection plug 22 is square or circular, the shape of the installation hole is correspondingly set to be square or circular. The length, width or radius of the installation hole matching the first power connection plug 22 ensures a good fit between the first power connection plug 22 and the installation hole. In order to improve the sealing performance between the first power connection plug 22 and the installation hole, a sealing gasket 4 can also be arranged inside the installation hole. The shape and size of the sealing gasket 4 match the installation hole and the first power connection plug 22, so that the first power connection plug 22 is hermetically connected to the side wall of the washing pot 1 to prevent the washing liquid from leaking.

[0037] For the washer heating device in the embodiment of the present application, the sealing gasket 4 includes a sealing gasket main body 41 and a first convex ring 42. The first power connection plug 22 includes a first plug main body ②②③ and a second convex ring 224. The sealing gasket main body 41 is arranged in the installation hole and sleeved on the first plug main body 221. The side surface of the first convex ring 42 facing the second convex ring 224 abuts against the second convex ring 42. The first power connection plug 22 and the sealing gasket 4 are coaxially arranged and the cross-section along their respective axes is in the shape of a "convex". The shape of the installation hole is cylindrical, and the installation hole is coaxially arranged with the first power connection plug 22 and the sealing gasket 4 respectively.

[0038] In conjunction with the above embodiments, the first plug body 223 and the sealing gasket body 41 of the sealing gasket 4 are installed in the mounting hole, and the first convex ring 42 and the second convex ring 224 are in surface contact and abutted together. The sealing gasket body 41 and the first plug body 223 serve to seal the mounting hole, and the first convex ring 42 abuts against the second convex ring 224, which helps to prevent the accumulation of oil, dust and other impurities on the first power connector 22.

[0039] In this embodiment of the washing machine heating device, the mounting hole is located at the bottom of one side of the washing pot 1, and the heating element 21 extends laterally into the bottom of the washing pot 1 with the extension direction perpendicular to the side of the washing pot 1; the first positive electrode contact 221, the first negative electrode contact 222, and the second positive electrode contact 31 extend laterally with the extension direction perpendicular to the side of the washing pot 1.

[0040] In conjunction with the above embodiments, a mounting hole is provided on the side wall near the bottom of the wash tank 1, and the heating element 21 is inserted laterally into the wash tank 1. Even when the liquid level of the washing liquid inside the wash tank 1 is low, the heater 2 can still heat the washing liquid. Furthermore, the heating element 21 is laterally positioned inside the wash tank 1 near the bottom, thereby increasing the contact area between the heating element 21 and the washing liquid and improving heating efficiency. The first positive contact 221, the first negative contact 222, and the second positive contact 31 extend perpendicularly to the side of the wash tank 1, facilitating the connection of the first positive contact 221, the first negative contact 222, and the second positive contact 31 to the vehicle's power supply.

[0041] The washing machine heating device of this application embodiment includes heating elements 21 comprising at least one of resistance wire, electric heating element, and electric heating rod. The number of heating elements 21 matches the volume of the washing pot 1; when there are multiple heating elements 21, the multiple heating elements 21 are arranged at equal intervals along the width or length direction of the washing pot 1.

[0042] refer to Figure 2 and Figure 3 As shown in the embodiment of this application, the heater 2 of the washer heating device can be a resistance wire heater, an electromagnetic heater, etc. Considering economy and durability, the heater 2 is preferably a resistance wire heater. The resistance wire heater 2 includes a resistance wire, a heating controller, and a first power connector 22. The resistance wire extends laterally into the wash tub 1. The heating controller is electrically connected to both the resistance wire and the first power connector 22. The first power connector 22 passes through the side wall of the wash tub 1 for connection to the vehicle's power supply and is sealed to the side wall of the wash tub 1.

[0043] In conjunction with the above embodiments, when the vehicle is a large vehicle, the front windshield and rear windshield have a large area, and a large amount of washing liquid is required for a single wash. Accordingly, the volume of the washing tank 1 will be designed to be larger. A single heating element 21 may not be able to heat up the washing liquid immediately. In this case, multiple heating elements 21 can be set up. The multiple heating elements 21 are arranged at equal intervals along the length or width of the washing tank 1. By heating simultaneously with multiple heating elements 21, the washing liquid can be heated up quickly.

[0044] refer to Figures 1 to 5 In the washing machine heating device of this application embodiment, a first temperature sensor 3 is installed on the washing pot 1 and is used to collect the liquid temperature of the washing liquid in the washing pot 1. A second temperature sensor is used to collect the ambient temperature of the vehicle. The controller is electrically connected to the heater 2, the first temperature sensor 3 and the second temperature sensor respectively. When the second temperature value collected by the second temperature sensor is lower than 0°, the controller is used to control the heater 2 to heat up. When the first temperature value collected by the first temperature sensor 3 is greater than or equal to the first set temperature value, the controller is used to control the heater 2 to stop heating.

[0045] In conjunction with the above embodiments, the first temperature sensor 3 collects the temperature of the washing liquid inside the wash tank 1 in real time, and the second temperature sensor collects the ambient temperature of the vehicle in real time. When the second temperature sensor detects that the ambient temperature is below 0°C, in order to prevent the washing liquid from freezing and affecting its normal use, the controller controls the heater 2 to start working, thereby heating the washing liquid inside the wash tank 1. When the first temperature sensor 3 detects that the liquid temperature of the washing liquid is greater than or equal to the set temperature value, the controller controls the heater 2 to stop working. This not only avoids overheating the washing liquid and causing it to become too hot, thus damaging the internal structure of the wash tank 1, but also saves energy and avoids excessive energy waste.

[0046] In this embodiment of the washing machine heating device, the controller is a remote controller, which is electrically connected to the second temperature sensor. When the vehicle is not in a driving state and the second temperature value collected by the second temperature sensor is lower than 0°C, the remote controller controls the heater to operate for a first set time. When the first temperature value collected by the first temperature sensor 3 is greater than or equal to 25°C, the remote controller controls the heater 2 to stop heating.

[0047] In conjunction with the above embodiments, the remote controller can be a portable device such as a mobile phone, tablet, or computer. The remote controller has an application installed inside that can remotely control the vehicle, and the ambient temperature of the vehicle collected by the second temperature sensor can be transmitted to the remote controller in real time.

[0048] Before driving, the driver obtains the ambient temperature of the vehicle via a remote controller. When the ambient temperature is below 0°C, the driver controls the heater 2 to heat the vehicle for 5 minutes via the remote controller. The first temperature sensor collects real-time data on whether the detergent temperature is greater than or equal to 25°C. If the detergent temperature meets the temperature requirement, the controller automatically stops the heater 2. This preheating of the detergent improves the driver's experience.

[0049] In this embodiment of the washing machine heating device, a heating starter is installed inside the vehicle and is electrically connected to the controller. When the vehicle is in driving mode and the second temperature value collected by the second temperature sensor is lower than 0°, the heating starter is used to provide a voice prompt to indicate whether heating is required. When the heating starter receives a command to heat, the controller is used to control the heater 2 to operate.

[0050] Based on the above real-time example, the heater starter can be a voice prompt or a physical heating button. Considering the needs of vehicle intelligence, a voice prompt is preferred. When the ambient temperature collected by the second temperature sensor is below 0°C while the driver is driving, the controller activates the voice prompt to ask whether the washer fluid needs to be heated. After the driver inputs the command to heat the fluid, the controller activates heater 2 to start heating.

[0051] In the washing machine heating device of this application embodiment, when the second temperature value collected by the second temperature sensor is lower than 0° and the first temperature value collected by the first sensor is lower than the second set temperature, the heating starter is used to provide a voice prompt to indicate whether to heat; when the heating starter receives an instruction to heat, the controller is used to control the heater 2 to stop for a third set time after heating for a second set time.

[0052] In conjunction with the above embodiments, when the ambient temperature of the vehicle is below 0°C and the liquid temperature of the washing liquid in the washer reservoir 1 is below 10°C, the controller activates a voice prompt to indicate whether heating is required. If a heating command is received, the controller controls the heater 2 to operate in a mode of heating for 2 minutes and then stopping for 5 minutes, until the liquid temperature of the washing liquid exceeds 25°C, at which point heating stops. This avoids heating the washing liquid when it is already at a high temperature, thus saving energy.

[0053] Based on the same inventive concept, this application also provides a washing kettle with a heating function. Since the implementation principle of the washing kettle with a heating function in this application is the same as or similar to the washing machine heating device in this application, the specific implementation of the washing kettle with a heating function can be referred to the washing machine heating device, and the repeated parts will not be described again.

[0054] The washing jug with heating function in this application embodiment is installed on a vehicle and contains washing liquid. The washing jug 1 is equipped with the heating device of any of the above embodiments.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
