Description
Technical Field
[0001] The utility model relates to the technical field of automatic detergent delivery, in particular to an automatic detergent filling device. Background Art
[0002] Existing automatic detergent filling devices usually use a dosing pump to pump detergent into the washing bin. The dosing pump extracts detergent from the filling box and injects the extracted detergent into the washing bin. In addition, a fixed dosing pump working time is usually set to control the amount of detergent injected into the washing bin.
[0003] However, since detergents generally have a certain viscosity and are greatly affected by ambient temperature, in a low temperature environment, the viscosity of the detergent may increase or even solidify, resulting in insufficient amount of detergent injected into the washing chamber, thus affecting the washing effect; while in a high temperature environment, the viscosity of the detergent decreases, resulting in excessive amount of detergent injected into the washing chamber, thus affecting the rinsing effect. Utility Model Content

[0006] Furthermore, the filling box includes a box body and a cover body arranged on the top of the box body, the bottom wall of the box body is inclined, the suction port is arranged at the lowest end of the bottom wall of the box body, and the sensing end of the temperature detection element extends to the suction port.

[0008] Further, the temperature detection element includes a temperature probe.
[0009] Furthermore, the temperature probe extends from the top of the filling box, and the bottom end of the temperature probe extends to the bottom of the filling box.
[0010] Furthermore, the temperature detection element is arranged on the top of the filling box and is located on a side away from the filling port.
[0011] Furthermore, it also includes a heating element for heating the detergent in the filling box. The heating element is connected to the controller signal. The controller is used to receive the temperature signal fed back by the temperature detection element and control the start and stop of the heating element.
[0012] Furthermore, the heating element is arranged at the suction port.
[0013] Furthermore, the heating element includes a heating tube arranged in the filling box; or a heating wire arranged on the outer wall of the filling box.
[0014] Furthermore, a heat insulation layer is provided on the filling box.
[0015] Furthermore, the filling port is provided with a liquid level indicating member extending toward the inside of the filling box.
[0016] The beneficial effects of adopting the utility model are as follows:

The sensing end of the temperature detection element is placed in the filling box, which is used to detect the temperature of the detergent in the filling box and feed the temperature signal back to the controller. The controller is used to receive the temperature signal fed back by the temperature detection element and control the working time of the pump body, thereby controlling the amount of detergent pumped into the pump body, achieving precise control of the dosage of the detergent, and ensuring that the appropriate amount of detergent can be pumped in under different temperature environments to ensure the washing and rinsing effects.
[0018] When the pump body is working, the detergent near the suction port is first extracted, and the detergent in other parts flows toward the suction port. The sensing end of the temperature sensing element extends to the suction port, which is convenient for detecting the temperature of the detergent near the suction port, and can accurately reflect the temperature of the detergent being pumped out, and further realize the precise control of the detergent injection amount;

DETAILED DESCRIPTION
[0025] With reference to the accompanying drawings, specific embodiments of the present invention will be described in detail.
[0026] Reference Figures 1 to 3 The utility model provides an embodiment of an automatic detergent filling device.
[0027] A detergent automatic filling device includes a filling box 100, which has a filling port 121 and a suction port 111. The filling port 121 is used to inject detergent into the filling box 100. Furthermore, a top cover 130 is provided above the filling port 121, and the top cover 130 is used to close the filling port 121. When detergent needs to be injected into the filling box 100, the top cover 130 is opened to expose the filling port 121. A sealing ring is provided between the filling port 121 and the top cover 130. Preferably, the sealing ring adopts a thin silicone or rubber structure to improve the sealing performance between the top cover 130 and the filling port 121, so as to prevent the high temperature generated when the washing device is running and working from evaporating the water in the detergent in the filling box 100, resulting in an increase in the viscosity of the detergent. Among them, a lock structure 140 is also provided between the top cover 130 and the filling box 100. The lock structure 140 includes a hook on the top cover 130 and a self-locking switch on the filling box 100. When the top cover 130 is pressed down, the hook is inserted into the self-locking switch and remains in a closed state; when the top cover 130 needs to be opened, the top cover 130 is pressed, and the self-locking switch releases the lock on the hook. One end of the top cover 130 is rotatably connected to the top of the filling box through a rotating shaft. In order to realize that the top cover 130 can automatically pop open when the top cover 130 is opened, a torsion spring 150 is provided near the rotating shaft. The top cover 130 is also provided with a fixing part at the rotating shaft. Both ends of the torsion spring 150 are fixed in the fixing part. When the self-locking switch releases the lock on the hook, the top cover 130 automatically pops open around the rotating shaft under the elastic force of the torsion spring 150.
[0028] The pump body 200 is connected to the suction port 111 for pumping out the detergent in the filling box 100. The pump body 200 is fixed to the outside of the filling box 100. The pump body 200 includes a discharge port 220 and a connecting pipe 210 connected to the suction port 111. When the filling box 100 is connected to the washing bin, the discharge port 220 is the washing bin interface. When the pump body 200 is working, the detergent is pumped into the pump body 200 from the suction port 111 through the connecting pipe 210 and is injected into the washing bin from the washing bin interface. Preferably, the suction port 111 is provided at the bottom of the filling box 100, so that the detergent in the filling box 100 can be pumped into the washing bin.
[0029] The temperature detection element 300 has a sensing end disposed in the filling box 100 and is used to detect the temperature of the detergent in the filling box 100 .
[0030] The controller is connected to the pump body 200 and the temperature detection element 300 by signal, and is used to receive the temperature signal fed back by the temperature detection element 300 and control the working time of the pump body 200, thereby realizing the control of the pumping amount. The working time of the pump body 200 is controlled according to the temperature-pump body working time correspondence table. Of course, the control system of the washing device can also be modified according to actual needs to adjust the working time of the pump body 200. The lower the detergent temperature, the longer the working time of the pump body 200, thereby ensuring that the detergent injected into the washing chamber is sufficient; the higher the detergent temperature, the shorter the working time of the pump body 200, thereby ensuring that the detergent injected into the washing chamber is not too much.
[0031] The temperature of the detergent in the filling box 100 is detected by the temperature detection element 300, and the temperature signal is fed back to the controller. The controller controls the working time of the pump body 200 according to the temperature of the detergent, and then controls the amount of detergent pumped by the pump body 200. In a low temperature environment, the detergent is too viscous, resulting in insufficient pumping, which affects the washing effect; or in a high temperature environment, the detergent is too thin, resulting in excessive pumping, which affects the rinsing effect. Accurate control of the dosage of the detergent is achieved to ensure that the right amount of detergent can be pumped in under different temperature environments to ensure the washing and rinsing effects.
[0032] For example, this embodiment provides a temperature-operating time correspondence table:
[0033] Detergent temperature (℃) Pump working time (s) 1-5 65 6-10 45 11-15 35 16-20 25 21-25 19 26-30 15 31-35 11 36-40 8
[0034] In some embodiments, the refill box 100 includes a box body 110 and a cover body 120 disposed on the top of the box body 110. Preferably, the box body 110 and the cover body 120 are integrally formed to ensure strength. The bottom wall of the box body 110 is inclined, and the suction port 111 is disposed at the lowest end of the bottom wall of the box body 110, so that the detergent flows into the vicinity of the suction port 111 under gravity, thereby ensuring that the detergent in the refill box 100 can be completely pumped into the washing bin to reduce residue. The sensing end of the temperature detection element 300 extends to the suction port 111, and the refill port 121 is disposed on the cover body 120.
[0035] In this way, when the pump body 200 is working, the detergent near the suction port 111 is preferentially extracted, and the detergent in other parts flows toward the suction port 111. The sensing end of the temperature detection element 300 is set near the suction port 111, which is convenient for detecting the detergent temperature near the suction port 111, and then can accurately reflect the temperature of the pumped detergent, and further realize the precise control of the detergent injection amount.
[0036] Furthermore, the bottom wall of the box body 110 includes an inclined section 112 and a sinking section 113 connected to the lowest end of the inclined section 112, the sinking section 113 has a sinking space, the inclined section 112 is an inclined inclined plate, and the sinking section 113 is a cylindrical groove. The sensing end of the temperature detection element 300 extends into the sinking space of the sinking section 113, the suction port 111 is provided at the bottom of the sinking space, and the filling port 121 is located at the highest point of the inclined section 112. At this time, the sinking section 113 serves as the lowest part of the box body 110. When the detergent is injected into the filling box 100 from the filling port 121, the detergent flows along the inclined section 112 to the sinking space of the sinking section 113 at the bottom, filling the sinking space. The suction port 111 extracts the detergent from the sinking space. At this time, the temperature detection element 300 only needs to detect the temperature of the detergent in the sinking space. Even if the remaining amount of detergent in the filling box 100 is small, the temperature detection element 300 can still detect the temperature of the detergent.
[0037] In some embodiments, the temperature detection element 300 can be disposed on the box body 110 or the cover body 120 of the filling box 100. As long as the sensing end of the temperature detection element 300 can extend to the bottom of the filling box 100, the temperature of the detergent in the filling box 100 can be detected. Preferably, the temperature detection element 300 is disposed on the top of the filling box 100, that is, the temperature detection element 300 is disposed on the cover body 120 and is located on a side away from the filling port 121. At this time, the temperature detected by the temperature detection element 300 will not be affected by the newly injected detergent.
[0038] Further, the temperature detection element 300 includes a temperature probe. When the temperature probe is disposed on the box body 110 of the filling box 100, it can extend from the bottom end of the side wall or the bottom of the box body 110 into the filling box 100, and the sensing end of the temperature probe extends to the sinking space of the sinking section 113; when the temperature probe is disposed on the cover body 120 of the filling box 100, the bottom end of the temperature probe extends to the bottom of the filling box 100, that is, the bottom of the temperature probe passes through the cover body 120 and extends downward to the sinking space at the bottom of the filling box 100, so as to detect the detergent temperature near the suction port 111.
[0039] In some embodiments, the automatic detergent filling device also includes a heating element for heating the detergent in the filling box 100. The heating element is connected to the controller signal, and the controller is used to receive the temperature signal fed back by the temperature detection element 300 and control the start and stop of the heating element. When the temperature detection element 300 detects that the temperature of the detergent in the filling box 100 is lower than the preset temperature, the heating element is turned on to reduce the viscosity of the detergent; when the temperature probe detects that the temperature of the detergent has reached the preset temperature, the heating element is turned off, and the pump body 200 is started to pump the detergent into the washing chamber. For example, the preset temperature is set to 1°C, and the heating element is turned on when the temperature probe detects that the detergent temperature is lower than 1°C, and the heating element is turned off after the temperature probe detects that the detergent temperature reaches 1°C, and the pump body 200 is turned on and off according to the temperature-pump body working time correspondence table.
[0040] Furthermore, a heat insulating layer is provided on the filling box 100 to keep the detergent warm and reduce the effect of the external ambient temperature on the viscosity of the detergent. Preferably, the heat insulating layer is made of a heat insulating material, such as polyurethane foam material, polystyrene board, etc.
[0041] The heating element can be arranged in the box body 110 of the filling box 100, and the heat insulation layer is wrapped around the outside of the filling box 100. Preferably, the filling box 100 directly serves as the heat insulation layer and is made of heat insulation material to prevent the detergent from losing temperature quickly after being heated, and further reduce the influence of the ambient temperature on the viscosity of the detergent. Preferably, the heating element is a heating tube extending into the box body 110, and the heating tube extends into the filling box 100 from the bottom of the box body 110 or the lower end of the side wall, so that the heating tube can be immersed in the detergent for a long time. Furthermore, the heating tube is arranged in the sinking space near the suction port 111. At this time, not only can the detergent near the suction port 111 be heated to ensure that the detergent is extracted from the suction port 111, but the sinking section 113 is the lowest point of the box body 110 at this time, and the heating tube is always located in the detergent to avoid dry burning. It can also heat only the detergent near the suction port 111, and the heated detergent is extracted to avoid repeated heating of the detergent in the box body 110.
[0042] In some embodiments, the heating element may also be arranged outside the box body 110, and the heat insulation layer is wrapped around the outside of the heating element to prevent the detergent from adhering to the heating element and affecting the service life of the heating element. Specifically, the heating element is a heating wire arranged on the outer wall of the filling box 100, and the box body 110 is made of heat transfer material. The heating wire is arranged close to the outer wall of the box body 110, and the detergent in the box body 110 is heated by the heat transfer of the box body 110 itself. Preferably, the heating wire is arranged at the suction port 111 at the bottom of the box body 110, and only the detergent near the suction port 111 is heated to reduce the viscosity of the detergent near the suction port 111.
[0043] In some embodiments, the filling port 121 is provided with a liquid level indicator 400 extending toward the interior of the filling box 100, and the liquid level indicator 400 is parallel to the detergent liquid surface and is used to indicate the filling position limit value. When a peristaltic pump is used as the filling pump body 200, the peristaltic pump extracts the detergent in the filling box 100. Therefore, the interior of the filling box 100 needs to be connected to the external atmosphere. If the detergent is filled too much, the filling port 121 will be completely sealed, so that the interior of the filling box 100 is completely isolated from the external atmosphere. When the peristaltic pump starts to pump, the external air cannot enter the filling box 100, which will cause the detergent to be unable to be smoothly extracted; at the same time, since the volume of the detergent may change with the increase of temperature, if too much detergent is added, the volume of the detergent increases after heating and may overflow the filling box 100. The above problem can be further avoided by setting the liquid level indicator 400.
[0044] In some embodiments, a liquid level detection component for detecting the level of detergent is provided in the box body 110. Specifically, the liquid level detection component includes a float 510, a guide column 520, and a float sensor 530. The guide column 520 is arranged near the suction port 111. Specifically, the lower end of the guide column 520 is arranged in the sinking space of the sinking section 113 and extends upward from the bottom of the box body 110. The float 510 is sleeved on the guide column 520, and there is a gap between the float 510 and the guide column 520 to prevent the float 510 from sticking to the guide column 520. The float sensor 530 is arranged at the bottom of the guide column 520, that is, the float sensor 530 is arranged in the sinking section 113, so that the float 510 and the float sensor 530 will be connected only when the detergent is reduced to the lowest level. The float 510 moves up and down on the guide column 520 as the detergent liquid level changes. When the detergent level drops, the float 510 drops accordingly and approaches the float sensor 530. The float sensor 530 issues a liquid level warning to prompt the user to add detergent. Preferably, the float sensor 530 is a reed switch, the float 510 is a low-density foamed PP material, and a magnetic sheet or a magnetic ring is provided inside the float 510 to cooperate with the reed switch.
