Example 1
The invention provides a detergent dosing device, as shown in fig. 1 to 4, comprising a dosing assembly 10, wherein the dosing assembly 10 comprises:
a chamber 11 for forming an accommodating space;
a duct 12 having a top end extending into the detergent storage box 20 and a bottom end extending into the chamber 11;
a siphon tube 13, the inlet section 131 of which has a curved structure and the port of the inlet section 131 extends downwards into the chamber 11, and the outlet section 132 extends downwards and is communicated with the barrel assembly 30;
a water inlet pipe 14 communicating with the chamber 11;
wherein the height of the outlet 121 at the bottom end of the conduit 12 is greater than the height of the port of the inlet section 131 and less than the height of the inner surface of the curved portion of the inlet section 131; the detergent in the detergent storage box 20 enters the bin 11 through the outlet 121, and after the liquid level in the bin 11 passes through the outlet 121, the detergent stops flowing downwards;
the water inlet pipe 14 is opened to allow water to enter, and when the liquid level in the chamber 11 is greater than the height of the inner surface of the curved portion of the inlet section 131, the siphon pipe 13 generates siphon to guide the mixed solution of water and detergent into the cartridge assembly 30.
In the embodiment, the automatic feeding is performed through the siphon effect, so that the scheme of the traditional liquid pump is replaced, the structure is simplified, and the cost is reduced. The bin 11 is arranged below the detergent storage box 20, and due to the principle of the difference between the internal and external atmospheric pressure at the outlet 121, the detergent in the detergent storage box 20 flows into the bin 11 through the outlet 121, a liquid pump is not required to provide driving force to automatically supplement the detergent into the bin 11, and when the detergent in the bin 11 passes through the outlet 121, the gas in the outlet 121 and the gas in the bin 11 cannot be exchanged, and the outlet 121 stops continuously flowing out of the detergent. In addition, through designing the height difference between the outlet 121 of the guide pipe 12 and the port of the inlet section 131 of the siphon pipe 13, so as to control the single detergent supplementing amount in the bin 11, realize quantitative detergent supplementing, simplify the controlled equipment, save the internal space and be beneficial to the miniaturized design of the clothes care device; by designing the height of the curved portion of the inlet section 131 to determine the liquid level in the chamber 11 when the siphon 13 is generated, the total amount of water and detergent at the time of single automatic feeding is determined, that is, water is fed through the water inlet pipe 14 so that the liquid level in the chamber 11 is higher than the height of the curved portion, at this time, the liquid level in the chamber 11 is the siphon liquid level, and the siphon 13 siphons to automatically feed the mixed liquid of water and detergent to the barrel assembly 30. And the height of the port of the inlet section 131 of the siphon pipe 13 is smaller than the height of the outlet 121 of the conduit pipe 12, on one hand, after the liquid level in the siphon to the bin 11 is lower than the height of the port of the inlet section 131, the outlet 121 is positioned above the liquid level locally, namely, the conduit pipe 12 can exchange gas with the bin 11 through the outlet 121, and based on the air pressure balance principle, the detergent in the detergent storage box 20 is reintroduced into the bin 11 through the conduit pipe 121, and a new round of quantitative detergent replenishment is started; on the other hand, the gap between the port of the inlet section 131 and the bottom wall of the bin 11 is reduced, so that the sufficient siphon feeding of the detergent is ensured. The dispensing assembly 10 has simple structure and low cost, does not need a liquid pump, and can control the single-time detergent dispensing amount.
It should be understood that the height of each component or each structure herein refers to the height of the highest point of the component or structure. Wherein the height of the outlet 121 represents the height at which the top surface profile of the inner wall of the outlet 121 is located; the port height of the inlet section 131, representing the height of the port outer contour; the height of the inner surface of the curved portion of the inlet section 131 means the height at which the highest point of the profile of the top surface of the inner wall of the curved portion of the inlet section 131 is located.
In one embodiment, the bottom end of the conduit 12 is connected to the bottom wall of the chamber 11, and the bottom end of the conduit 12 is opened toward one side of the siphon tube 13 to form the outlet 121. Specifically, the design of the opening structure reduces the size of the outlet 121 to control the amount of detergent flowing out of the duct 12 so as not to splash to the peripheral side surface of the chamber 11 due to too fast inflow of the detergent, thereby preventing accurate control of the single detergent amount.
Further, the water inlet pipe 14 and the siphon pipe 13 are respectively positioned at two sides of the conduit 12. Specifically, the inlet pipe 14 is located on the side of the conduit 12 facing away from the outlet 121, so that when water is fed into the inlet pipe 14, the water flows quickly into the conduit 12 from the outlet 121, thereby influencing the concentration of detergent in the conduit 12 and further influencing the control of the subsequent single detergent amount.
In one embodiment, the water inlet pipe 14 is connected to the position of the chamber 11 above the curved portion of the inlet section 131, that is, the contour height of the bottom surface of the inner wall of the inlet end of the water inlet pipe 14 is greater than the height of the inner surface of the curved portion of the inlet section 131, so that the water mixed with the detergent enters the water inlet pipe 14 when the liquid level in the chamber 11 reaches the siphon liquid level, and the water inlet pipe 14 is polluted and is not easy to clean.
In one embodiment, the inlet end of the inlet pipe 14 is provided with a solenoid valve (not shown), the waterway is used for introducing water into the inlet pipe 14, and the water in the inlet pipe 14 naturally flows into the bin 11 under the water pressure.
Further, the single water inflow of the chamber 11, i.e., the liquid level in the final chamber 11, is controlled by controlling the amount of water that is introduced into the water inlet pipe 14 by the water passage in a single time.
In an embodiment, the chamber 11 is an integral piece with the conduit 12 and/or the siphon 13. Specifically, the chamber 11 and the conduit 12 are integrally formed, so as to simplify the assembly of the chamber 11 and the conduit 12 and improve the tightness between the conduit 12 and the chamber 11; the siphon tube 13 is detachably connected to the chamber 11 to facilitate the removal of the siphon tube 13, so as to facilitate the cleaning of the siphon tube 13 to prevent the siphon tube 13 from clogging with detergent. Or the bin 11 and the siphon tube 13 are integrally formed parts, so that the assembly of the bin 11 and the siphon tube 13 is simplified, and the tightness between the bin 11 and the siphon tube 13 is improved; the duct 12 is detachably connected to the chamber 11 to facilitate replacement of the duct 12 or cleaning of the duct 12 to facilitate smooth flow of the detergent. Or, the chamber 11, the guide tube 12 and the siphon tube 13 are integrally formed to simplify assembly and improve sealability.
In one embodiment, as shown in fig. 3 and 4, the overflow pipe 15 is further included, one end of which is connected to the position of the chamber 11 above the bending position of the inlet section 131 through a one-way valve, and the other end of which is connected to the barrel assembly 30. Specifically, when too much water is introduced into the chamber 11 through the water inlet pipe 14, the water in the chamber 11 flows back into the water inlet pipe 14, and by providing the overflow pipe 15, the too much water flows into the barrel assembly 30 through the overflow pipe 15, so that on one hand, the pollution of the water inlet pipe 14 by the detergent mixed in the water is avoided, and on the other hand, the reduction of the single detergent dosage is avoided. In addition, the chamber 11 performs gas exchange with the cylinder assembly 30 through the overflow pipe 15, thereby achieving air pressure balance. In yet another embodiment, the chamber 11 is provided with an air pressure balancing hole to balance the air pressure of the chamber 11 as the liquid level in the chamber 11 changes.
Further, the overflow pipe 15 and the water inlet pipe 14 are respectively connected to left and right parts of the same height at one side of the chamber 11.
Further, the water inlet end of the water inlet pipe 14 is extended upward so as to facilitate water inlet.
Further, the overflow pipe 15 is bent downward toward the cartridge assembly 30 so as to drain excessive water introduced into the chamber 11.
In one embodiment, the structure of the dispensing assembly 10 of fig. 1 and 2 is specifically described. H in FIG. 2 a The line indicates the height of the outlet 121, i.e. the level of liquid in the chamber 11 reaches h a At the time of the line, the detergent storage box 20 stops flowing down the detergent; h is a b The line represents the height of the port of the inlet section 131 of the siphon 13; h is a c The line indicates the height of the inner surface of the inlet segment 131 at the bend, i.e., the liquid level in the plenum 11 is above h c At line, siphoning begins. During automatic dispensing, the detergent in the detergent storage box 20 flows downwards through the conduit 12 and flows into the bin 11 from the outlet 121, and when the height of the detergent in the bin 11 reaches h a When the line is running, the detergent passes through the outlet 121, and the duct 12 does not exchange gas with the chamber 11, and at this time, the detergent in the detergent storage box 20 stops flowing into the chamber 11, and the height of the detergent in the chamber 11 is maintained at h a The line is unchanged. Inlet pipe 14 is filled with water when the liquid level in chamber 11 reaches h c When the line is drawn, the siphon tube 13 starts siphoning, and the mixed liquid of the water and the detergent in the chamber 11 is introduced into the cylinder assembly 30. When the liquid level in the chamber 11 decreases to h b Below the line, the siphon 13 breaks away from the liquid level in the bin 11, stopping the siphon, i.e. the single detergent dosing is over.
It will be appreciated that the port representing the inlet section 131 of the siphon 13 is very close to the bottom wall of the plenum 11, when the liquid level in the plenum 11 drops to h b When siphoning is stopped below the line, the accuracy of the automatic dispensing amount is extremely low and the effect of the liquid remaining in the chamber 11 is negligible.
Example 2
The invention provides a clothes treatment device, as shown in fig. 1 to 4, which comprises a device body 100, wherein the device body 100 comprises a cylinder assembly 30 and the detergent quantitative feeding device, so that the structure of the device body 100 is simplified, the energy consumption and the structure cost of automatic feeding are reduced, and the feeding amount of single detergent is controllable.
Example 3
The invention provides a quantitative delivery method, as shown in fig. 5, comprising the following steps:
s11, when the liquid level in the bin 11 is lower than the height of the outlet 121 of the guide pipe 12, the detergent in the detergent storage box 20 flows to the bin 11 until the liquid level floods the outlet 121; that is, the detergent in the detergent storage box 20 flows into the bin 11 through the duct 12 to the outlet 121 of the level flooding duct 12, and the flow of the detergent is stopped to complete the quantitative replenishment of the detergent in the bin 11;
s12, configuring a water inlet pipe 14 to feed water and mixing to form a mixed solution;
and S13, when the liquid level of the mixed solution exceeds the height of the inner surface of the bent part of the inlet section 131 of the siphon tube 13, a siphon effect is generated so as to perform quantitative feeding into the barrel assembly 30.
In one embodiment, as shown in FIG. 5, the method comprises the steps of:
s21, acquiring the weight of clothes to determine the required detergent amount;
s22, acquiring single detergent dosage of the dosage assembly 10;
s23, matching the automatic throwing times of the throwing assembly 10 according to the detergent demand and the single detergent throwing amount;
s24, executing detergent delivery according to the automatic delivery times. Specifically, the number of automatic dispensing times of the dispensing assembly 10 can be matched by a calculation formula of the detergent demand and the single detergent dispensing amount. If the required detergent amount is 30mg and the single detergent dosage amount is 15mg, the automatic dosage number can be determined to be two, and the control unit sends an automatic dosage command to be executed twice to the automatic dosage assembly 10 to control the detergent dosage amount of each washing program.
Further, since the clothes are in various types and weights, in order to simplify the automatic putting procedure and match the single detergent putting amount determined by the automatic putting assembly 10 due to the structural design, a matching library, that is, a matching library of the weight range of clothes and the detergent required amount is provided. For example, the laundry weight is 1.5Kg or less, and the detergent demand is 15mg; the weight of the clothes is below 1.5-3Kg, and the detergent demand is 30mg.
In an embodiment, the method further comprises the steps of:
acquiring the actual water inflow of the water inlet pipe 14;
judging whether the actual water inflow is larger than a preset water inflow value of the water inlet pipe 14;
if so, the junction of overflow 15 and chamber 11 is opened to introduce excess water into inlet 14 and drain it into barrel assembly 30, so as to prevent water in chamber 11 from flowing back into inlet 14.
Further, the method further comprises the steps of:
acquiring whether the liquid level in the bin 11 is greater than or equal to a preset liquid level value;
if so, it is determined that the actual water intake is greater than the preset water intake value of the water intake pipe 14. Specifically, by setting a liquid level sensor in the chamber 11, it is determined in real time whether the actual water inflow is greater than the preset water inflow value of the water inlet pipe 14, and the structure is simple and easy to operate.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; those skilled in the art can smoothly practice the invention as shown in the drawings and described above; however, those skilled in the art will appreciate that many modifications, adaptations, and variations of the present invention are possible in light of the above teachings without departing from the scope of the invention; meanwhile, any equivalent changes, modifications and evolution of the above embodiments according to the essential technology of the present invention still fall within the scope of the present invention.
