Possibly, as shown in fig. 2 to 4, the detergent dispensing device of the present utility model comprises a storage structure and a dispensing structure, the storage structure comprises a storage part 1 and a vent pipe 3, the dispensing structure comprises a mixing part 2 and a siphon pipe 4, a mixing cavity 21 is formed in the mixing part 2, an opening 23 and a detergent inlet 22 which are communicated with the mixing cavity 21 are formed in the mixing part 2, a liquid storage cavity 11 is formed in the storage part 1, a detergent outlet 12 communicated with the liquid storage cavity 11 is further provided, a vent hole 13 which is positioned above a liquid level line 14 of the liquid storage cavity 11 is further provided, the detergent inlet 22 is connected with the detergent outlet 12, a first end of the vent pipe 3 is connected with the vent hole 13, a second end 31 of the vent pipe 3 is communicated with the mixing cavity 21, the siphon pipe 4 is communicated with the mixing cavity 21, and the liquid in the mixing cavity 21 is siphoned out when the liquid level in the mixing cavity 21 is equal to a preset liquid level, wherein the preset liquid level is higher than the second end 31, the liquid level which is the siphon pipe 4 is generated, and preferably the position of the second end 31 is higher than the position of the detergent inlet 22.
It will be appreciated that the reservoir 11 in the storage portion 1 is adapted to store a detergent and has a level line 14, i.e. the level line 14 must not be raised when the detergent is added to the reservoir 11, so as to ensure that air can enter the reservoir 11 through the ventilation pipe 3, and that the storage portion 1 may be provided with a detergent dispensing opening 15 and a cover 8, e.g. the detergent dispensing opening 15 is provided at the top thereof, or may be provided at other positions, e.g. a side wall or the like, and that the cover 8 is covered by the detergent dispensing opening 15, so that the detergent can be placed into the reservoir 11 when the cover 8 is opened, and that the cover 8 is covered after the detergent is placed.
The working principle of the detergent dispensing device of the present utility model will be described.
Because the second end 31 of the breather pipe 3 is communicated with the mixing cavity 21, external gas can enter the liquid storage cavity 11 from the breather pipe 3, due to the principle of a communicating vessel, the detergent in the liquid storage cavity 11 can flow into the mixing cavity 21 from the detergent outlet 12 and the detergent inlet 22, the detergent in the mixing cavity 21 can be gradually increased until the detergent submerges the second end 31, so that the gas cannot enter the liquid storage cavity 11 from the second end 31, and due to the balance of air pressure, the detergent in the liquid storage cavity 11 stops flowing, namely, when the overflow liquid level 25 as shown in the drawing is reached, when the washing machine is used for washing clothes, the detergent is required to be put in, the water is injected into the mixing cavity 21 through the opening 23, so that the detergent is mixed with the water, and when the mixed liquid reaches the preset liquid level, the siphon 4 is siphoned, so that the mixed liquid in the mixing cavity 21 is completely siphoned, and the detergent is put in once. After the end of the dispensing, the detergent in the storage part 1 is again introduced into the mixing chamber 21, and the above-described process is repeated, thereby completing the quantitative dispensing of the detergent a plurality of times.
Possibly, the detergent outlet 12 of the present utility model is located at the bottom of the side wall of the storage part 1, and the detergent inlet 22 is located at the bottom of the side wall of the mixing part 2. The specific arrangement mode of the connection between the detergent outlet 12 and the detergent inlet 22 includes various modes, for example, the detergent outlet 12 and the detergent inlet 22 are integrally connected, for example, the storage part 1 and the mixing part 2 share one side wall, the side wall separates a large cavity formed by the two side walls together to form two sub-cavities, the two sub-cavities are the mixing cavity 21 and the liquid storage cavity 11, and an opening is arranged on the side wall, and is formed by the detergent outlet 12 and the detergent inlet 22; of course, the detergent outlet 12 and the detergent inlet 22 may be connected by other means, such as direct connection of the detergent outlet 12 and the detergent inlet 22, or connection of the detergent outlet 12 and the detergent inlet 22 through a pipeline, etc.
The mixing portion 2 may have a groove structure with an open top, the opening at the top is the opening 23, and the water outlet 24 of the mixing portion 2 may be disposed on the bottom wall of the mixing portion 2. Of course, the above arrangements are merely exemplary, and one skilled in the art can adjust the specific arrangement.
The specific implementation of the communication between the second end 31 of the vent pipe 3 and the mixing chamber 21 may also include various embodiments, for example, the mixing portion 2 is provided with an air port, the second end 31 of the vent pipe 3 is connected to the air port, or the vent pipe 3 is directly inserted into the mixing chamber 21, so long as the second end 31 can be communicated with the mixing chamber 21, and the arrangement manner can be adjusted, which is within the scope of the present utility model.
As a possible embodiment, the inlet of the siphon 4 is located at the bottom of the mixing chamber 21 with a distance from the bottom wall of the mixing chamber 21, and the outlet of the siphon 4 is in communication with the water outlet 24, e.g. the siphon 4 is arranged through the water outlet 24.
After the detergent in the liquid storage chamber 11 flows into the mixing chamber 21, the detergent enters the siphon 4 from the inlet of the siphon 4, and the preset liquid level is higher than the second end 31, that is, the liquid level of the siphon 4 is higher than the second end 31 (such as the top end of a straight pipe in the siphon 4 in the figure), so that the siphon phenomenon cannot be caused after the detergent is immersed in the second end 31 of the breather pipe 3, after water is injected into the mixing chamber 21 from the opening 23, the liquid level of the formed mixed liquid gradually rises until the siphon liquid level is reached, and the siphon phenomenon starts to be generated, so that the mixed liquid in the mixing chamber 21 is sucked completely, and the mixed liquid is discharged into the washing chamber from the water outlet 24. The arrangement mode can enable the detergent delivery device to automatically, quantitatively deliver for many times, has a simple structure and greatly reduces the production cost. The siphon tube 4 may be an inverted U-shaped tube, or may be a matching structure of a siphon cap and a straight tube in the figure.
Alternatively, the water outlet 24 of the mixing part 2 may be provided with an electromagnetic valve, and when the detergent is mixed with the water source, the electromagnetic valve is closed, and after the mixing is completed, the electromagnetic valve is opened, which does not deviate from the principle of the utility model, and all the electromagnetic valves are within the protection scope of the utility model.
Since the dispensing structure doses the detergent into the mixing chamber 21 each time the detergent is dispensed into the washing chamber, the storage portion 1 is filled with detergent at the overflow level 25.

That is, when detergent needs to be put into the washing chamber of the drum washing machine, water enters the water inlet channel 62 from the water inlet end 61 of the water inlet structure 6 and finally is injected into the mixing chamber 21, and as the water seal portion 621 is formed on the water inlet channel 62, after the detergent and the water injected into the mixing chamber 21 are put into the washing chamber under the action of the siphon tube 4, the water seal portion 621 stores water, thereby achieving the effect of liquid seal and preventing the solidification of the detergent put into the mixing portion 2 again by the storage portion 1.
It can be understood that, as shown in fig. 5, the siphon liquid level difference H2 is far greater than the water seal liquid level difference H1, and the air pressure difference is equal to the pressure difference generated by the siphon liquid level difference, that is, pgh2=p0-P1, so the air pressure difference is far greater than the pressure difference generated by the water seal portion 621, that is=p0-P1 > pgh 1, and at this time, the air can continuously pass through the water seal portion 621 to reach the mixing chamber 21 under the action of the air pressure.
Further, referring to fig. 3 and 4, the water outlet end 63 of the water inlet structure 6 is submerged in the detergent received by the mixing chamber 21. I.e. the water outlet end 63 of the water inlet structure 6 is not higher than the position where the second end 31 is located.
Since one of the factors affecting the solidification of the detergent is the contact area with the air, the water outlet end 63 of the water inlet structure 6 is immersed in the detergent in the mixing cavity 21, so that the contact area of the detergent with the air is reduced, the effect of double sealing is achieved, and the solidification of the detergent is further prevented.
Possibly, the water inlet end 61 of the water inlet structure 6 is in an inverted cone shape, and the periphery of the water inlet end 61 is clamped to the opening 23, so that the water inlet structure 6 and the opening 23 can form a seal. In addition, since the water inlet end 61 is formed in an inverted cone shape, water injection is facilitated and splashing is prevented.
It is understood that the specific form of the sealing connection between the water inlet structure 6 and the opening 23 of the present utility model is not limited to the above embodiment, for example, the periphery of the water inlet structure 6 and the opening 23 may be integrally formed to achieve sealing, or the periphery of the water inlet structure 6 may be adapted to the opening 23 and interference fit, etc., which do not deviate from the principles of the present utility model and are within the scope of the present utility model.
