[0002] Generally, in the case where the windshield of an automobile is difficult to secure the front view during driving due to foreign substances such as dust, the driver can remove the foreign substances while spraying cleaning fluid to the windshield using a wiper to maintain the cleanliness of the windshield.

[0003] In addition, although there is a tendency that many vehicles are equipped with various sensors, according to the road environment (snow, rainy weather, etc.), if the sensor is contaminated or clogged with pollutants, the sensor is difficult to operate normally, and thus the necessity of cleaning the sensor using cleaning fluid is increasingly highlighted.

[0004] Such cleaning fluid is in a cold state due to the air temperature in an area where the air temperature is zero or in winter, and thus not only the function of the cleaning fluid cannot be fully exerted, but also in the case where the air temperature suddenly drops, there is a problem that the cleaning fluid is in a state where it cannot be used due to freezing.

[0005] In order to overcome this problem, a device for heating the cleaning fluid is being installed in a reservoir tank in which the cleaning fluid is stored.

[0006] However, the prior art is to install a water level measuring sensor and a heater, etc. as functional components in the reservoir tank, but such functional components need to be separately installed and wired to the motor pump, and thus there is a problem that the wiring operability is reduced, and in the case where the functional components fail, the reservoir tank itself needs to be removed, and thus there is a problem that the maintainability is low and the repair cost increases.

[0042] Figure 1 is a perspective view of a cleaning pump module 10 according to an embodiment of the present application, Figure 2 is a perspective view showing the inside of a housing of the cleaning pump module 10 according to an embodiment of the present application. Figure 3 is Figure 2 is an exploded perspective view of the cleaning pump module 10 of Figure 4 is an exploded perspective view of a heater assembly 100 according to an embodiment of the present application.

[0043] Referring to Figures 1 to 3 , the cleaning pump module 10 according to an embodiment of the present application can include the heater assembly 100, a connection assembly 200, and a fixing assembly 300.

[0044] The heater assembly 100 can function to heat a cleaning liquid and supply the heated cleaning liquid to the cleaning pump 230.

[0045] Specifically, the heater assembly 100 according to an embodiment of the present application can include a heater portion 130 including a plurality of heaters, a main body portion 110 housing the heater portion, and a first housing 120 surrounding the heater portion 130 and the main body portion 110.

[0046] Referring to Figure 4 , in an embodiment of the present application, the heater portion 130 can include a heater 131 and a heater cover 132.

[0047] The heater 131 is a heat source of the heater assembly 100 and generates heat by applying an electric current. The heater 131 is a positive temperature coefficient (PTC) heater that can be configured using a thermistor having a characteristic of sharply increasing in resistance when reaching a predetermined temperature after a temperature rise. That is, the heater 131 has a self-regulation function according to a surrounding temperature and a heat dissipation condition when an appropriate voltage is applied, and thus can maintain a predetermined temperature even without a separate controller. A material of a heating body of the positive temperature coefficient (PTC) heater can be a material including barium titanate (BaTiO3) as a basic component and adding lanthanum (La), niobium (Nb), strontium (Sr), lead (Pb), and manganese (Mn), or a zinc-titanium-nickel-oxygen (Zn-Ti-Ni-O) system ceramic.

[0048] In addition, the heater cover 132 can be combined with the heater 131 and accommodate a heater O-ring (not shown). The heater O-ring (not shown) functions to block the flow of a cleaning solution into the heater accommodation portion 111.

[0049] In an embodiment of the present application, the main body portion 110 can accommodate the heater portion 130 and be combined with the first housing 120.

[0050] Specifically, the heater accommodation portions 111 each accommodating a plurality of heaters 131 can be formed on an outer surface of the main body portion 110, and the heater accommodation portions 111 can be arranged apart from each other along the outer surface of the main body portion 110. The heater accommodation portions 111 can be formed along a length direction (x direction) of the main body portion 110, and can be formed to have a predetermined depth from the outer surface of the main body portion 110 to be able to accommodate the entire or a predetermined portion of the heater portion 130.

[0051] Further, the main body portion 110 can further include a guide portion 114 guiding a terminal (not shown) supplying an electric current to the heater 131. The guide portion 114 can be formed extending from a side surface of the main body portion 110 adjacent to the heater accommodation portion 111 toward the fixing assembly 300. Such a guide portion 114 can be formed in a tube shape having an inner hollow, and the terminal (not shown) can be connected to the heater 131 by penetrating the guide portion 114.

[0052] In addition, in an embodiment of the present application, the body part 110 can be formed hollow 113 inside in the length direction (x direction). Accordingly, the body part 110 can be roughly divided into an outer surface part and the hollow 113 which is a space formed inside. Such a hollow 113 can communicate with the pump inlet 231 of the washing pump 230 so that the washing liquid can be sucked into the pump inlet 231 after passing through the hollow 113.

[0053] In the washing pump module 10 according to an embodiment of the present application, the body part 110 can include a heating flow path 112. Such a heating flow path 112 can guide the washing liquid flowing in from the washing liquid flow inlet 101 formed in the first housing 120 to move to the washing pump 230 through the heating flow path 112 formed between the heater parts 130.

[0054] Hereinafter, the structure and the role of the heating flow path 112 will be described in detail.

[0055] Figure 5 is a perspective view illustrating the body part 110 of the heater assembly 100 of Figure 4 . Figure 6 is a front view of the washing pump module 10 according to an embodiment of the present application, Figure 7 is a cross-sectional view of the washing pump module 10 taken along A-A' of Figure 6 .

[0056] Referring to Figures 5 to 7 , in an embodiment of the present application, the heating flow path 112 can be formed along the outer surface of the body part 110 and connected with the hollow 113. The heating flow path 112 can be formed in a groove shape having a predetermined depth from the outer surface of the body part 110 in the length direction of the body part 110.

[0057] For example, the heating flow path 112 can have a predetermined depth D1 from the outer surface of the body part 110 and can have a width W1 narrower than the length direction. Also, when a surface of the body part 110 which is in contact with the fixing assembly 300 is referred to as a back surface and the opposite surface thereof is referred to as a front surface, the heating flow path 112 can be formed to have a predetermined depth D2 from the front surface of the body part 110 at a portion in contact with the front surface of the body part 110. That is, the heating flow path 112 can include the entire flow path extending to the inside of the hollow 113 from the side surface of the body part 110.

[0058] By the structure as described above, the washing liquid can flow in the direction of the arrow shown in Figure 7 . Specifically, the washing liquid flowing in to the washing liquid flow inlet 101 flows along the heating flow path 112 formed in the length direction of the side surface of the body part 110, is bent to flow at the front surface of the body part 110, and is U-shapedly returned to the inside direction U of the hollow 113, so that it can flow in the direction of the pump inlet 231.

[0059] In the cleaning pump module 10 according to an embodiment of the present application, since the heating flow path 112 is formed between the plurality of heater housing portions 111, the cleaning liquid flowing along the heating flow path 112 can be gradually heated by the heat generated by the heater portion 130.

[0060] Also, in the case where the cleaning liquid flows along the heating flow path 112 structure described above in a U shape, the cleaning liquid can stay around the heating element for a longer time than when passing through the heating element once, and thus the cleaning pump module 10 according to an embodiment of the present application can effectively warm up the cleaning liquid.

[0061] In an embodiment of the present application, when the heating flow path 112 is formed in a groove shape having a predetermined depth from the outer surface of the main body portion 110 in the length direction of the main body portion 110, the heating flow path 112 can be secured by sealing the open portion of the groove by the combination of the main body portion 110 and the first housing 120.

[0062] Referring again to Figure 4 As described above, in the case where the first housing 120 is combined with the main body portion 110, the groove formed on the outer surface of the main body portion 110 is covered by the first housing 120 to form a space in a pipe shape, thereby securing the heating flow path 112.

[0063] In addition, in an embodiment of the present application, the main body portion 110 can further include a guide portion 116 in the hollow 113. The guide portion 116 can be formed in the length direction of the main body portion 110 and can be a plate-shaped protrusion protruding from the inner surface of the hollow 113 toward the center portion. Such a guide portion 116 can be positioned opposite to the heating flow path 112 formed on the outer surface of the main body portion 110 and formed on the inner surface of the hollow 113.

[0064] Such a guide portion 116 can perform a guide function to flow the cleaning liquid flowing into the hollow 113 in the length direction of the main body portion 110.

[0065] In an embodiment of the present application, the main body portion 110 can be formed of a thermally conductive material. For example, the main body portion 110 can be formed of copper, silver, aluminum, or the like having a high thermal conductivity, which is the same as the material of the heat dissipation plate, or formed of an alloy thereof.

[0066] Accordingly, in the cleaning pump module 10, since the heat released from the heater 131 is transferred to the main body portion 110, the efficiency of heating the cleaning liquid passing through the heating flow path 112 of the main body portion 110 can be improved.

[0067] Referring again to Figure 1In an embodiment of the present application, the first case 120 of the heater assembly 100 can be formed with a cleaning solution flow inlet 101 through which an external cleaning solution flows. The cleaning solution flow inlet 101 can be formed in a hole or groove shape through the outer surface and the inner surface of the first case 120 at a predetermined area. The predetermined area can be an area 121 formed at an end of the first case 120 and having one side surface open. For example, the first case 120 can form the cleaning solution flow inlet 101 at an end portion where the fixing assembly 300 is coupled, and the cleaning solution drawn in through the cleaning solution flow inlet 101 can pass through the heating flow path 112.

[0068] Further, the first case 120 can be coupled to the main body 110 and the heater cover 132 in close contact with the remaining area except for the cleaning solution flow inlet 101. Accordingly, the first case 120 can prevent the heater cover 132 from being separated, and can prevent the cleaning solution from being introduced and discharged in the area except for the cleaning solution flow inlet 101.

[0069] In an embodiment of the present application, the cleaning solution flow inlet 101 can be formed at an end of the first case 120 and at a position corresponding to the heating flow path 112 of the main body 110. Thus, the cleaning solution in the reservoir can flow into the heating flow path 112 through the cleaning solution flow inlet 101.

[0070] In an embodiment of the present application, the first case 120 can be formed of a thermally conductive material. For example, the first case 120 can be formed of copper, silver, aluminum, or the like, which has a high thermal conductivity, such as a material of a heat sink, or can be formed of an alloy thereof. Further, the first case 120 can be formed of the same material as the main body 110.

[0071] Thus, the first case 120 can receive heat from the internal heater 130 and the main body 110 and release heat to the outside. That is, the cleaning solution in the reservoir, which is adjacent to the heater assembly 100, can receive the heat released from the first case 120, and thus flow into the cleaning solution flow inlet 101 in a state in which the temperature is increased to a certain degree. Accordingly, the efficiency of the heater assembly 100 that heats the cleaning solution can be improved.

[0072] Referring again to Figures 1 to 3 In an embodiment of the present application, the connection assembly 200 can include a cleaning pump 230 and a second case 210.

[0073] The second case 210 can function to accommodate electric wires of respective detailed components of the cleaning pump module 10, and can further include a connector 220. Further, the second case 210 can surround and protect the cleaning pump 230.

[0074] The cleaning pump 230 can function to suck the cleaning liquid passing through the heater assembly 100 and discharge it to the outside. In an embodiment of the present application, the cleaning pump 230 can be a brushless direct current motor (BLDC) pump, but is not limited thereto.

[0075] The cleaning pump 230 includes a pump inlet 231, and the pump inlet 231 can be combined with the hollow 113 of the heater assembly 100 in such a manner that the cleaning liquid passing through the hollow 113 can flow into the cleaning pump 230 through the pump inlet 231.

[0076] Referring again to Figures 1 to 3 In an embodiment of the present application, the fixing assembly 300 can include a third housing 320 and a water level measuring sensor 310.

[0077] The third housing 320 can function to combine and fix the media of the heater assembly 100 and the connection assembly 200. The third housing 320 can include a sensor holder 340 combined with the water level measuring sensor 310.

[0078] The water level measuring sensor 310 can be combined to the sensor holder 340 combined with one end of the third housing, and can be disposed on the heater assembly 100. Specifically, the sensor holder 340 can be combined to the upper end of the third housing 320, and can be formed to protrude in the direction of the heater assembly 100 from the third housing 320. Thus, the heater assembly 100 can form a first receiving groove 115 at the end of the main body part 110, and a second receiving groove 122 at the end of the first housing 120, so as to receive the protruding area of the sensor holder 340. And, in the state that the first housing 120 is combined to the main body part 110, the first receiving groove 115 can overlap the second receiving groove 122.

[0079] The water level measuring sensor 310 can be a capacitive sensor or a pressure measuring sensor. The capacitive sensor senses by the principle of detecting the change in capacitance between the electrodes installed in the water level measuring sensor 310, that is, senses the remaining amount of the cleaning liquid by detecting the change in capacitance generated between the cleaning liquid and the water level measuring sensor 310.

[0080] In addition, the pressure measuring sensor measures by converting the pressure or change in pressure measured by the sensor into an electric signal, and can measure the water level by the pressure varying according to the water level in the liquid storage tank.

[0081] In addition, the sensor holder 340 can receive the water level measuring sensor 310, and can be formed in a detachable structure for easy replacement.

[0082] Figure 8is a side view showing an embodiment in which the washing pump module 10 according to an embodiment of the present application is applied to the liquid storage tank 20.

[0083] Referring to Figure 8 In the case where the washing pump module 10 is combined with the liquid storage tank 20, the water level measuring sensor 310 and the heater assembly 100 are disposed inside the liquid storage tank 20 and can be a portion immersed in the washing liquid. In addition, the connection assembly 200 can be disposed outside the liquid storage tank 20.

[0084] In other words, with the fixed assembly 300 as a reference, the heater assembly 100 and the water level measuring sensor 310 can be located inside the liquid storage tank 20 and immersed in the washing liquid, but the fixed assembly 300 and the connection assembly 200 can be located outside the liquid storage tank 20.

[0085] In the washing pump module 10 according to an embodiment of the present application, when it is determined that the washing liquid is in a state of freezing or physical property inconsistency through a vehicle external air temperature sensor or the like, the heater 131 can be activated to restore the physical property value of the washing liquid inside the liquid storage tank 20, and the washing pump 230 can apply pressure to the washing liquid having the restored physical property value and deliver it from the liquid storage tank 20 to a destination (to a final spray nozzle).

[0086] In performing the above-described process, the water level measuring sensor 310 can continuously confirm the washing liquid level inside the liquid storage tank 20 and transmit information on the water level.

[0087] The washing pump module according to an embodiment of the present application modularizes functional components other than the liquid storage tank into one, thereby being capable of improving maintainability.

[0088] In addition, the washing pump module according to an embodiment of the present application can raise the washing liquid in temperature at one time by releasing heat from the housing of the heater assembly to the washing liquid in the periphery, and can improve efficiency in heating the washing liquid by applying a heating flow path that controls the flow of the washing liquid flowing into the heater assembly.

[0089] The above description has been made centering on preferred embodiments of the present application. It will be understood by those skilled in the art to which the present application pertains that the present application can be realized in modified forms without departing from the essential characteristics of the present application. Therefore, the above-described embodiments disclosed are not to be considered in a limiting sense, but are to be considered in the sense of a description. The scope of the present application is not limited by the above description, but is defined by the appended claims, and all differences within the scope equivalent to the scope are to be interpreted as included in the present application.
