Description

Technical Field

[0001] The present application relates to the field of treatment agent delivery, and in particular to a treatment agent delivery device and a washing device. Background Art

[0002] Washing equipment often needs to add treatment agents during the washing process. Taking washing machines as an example, treatment agents such as laundry detergent and softener need to be added. Since manual addition of treatment agents requires additional operations and the amount and timing of addition are difficult to accurately grasp, washing machines with automatic addition functions are becoming more and more popular. Most of the related automatic addition devices use electric-driven peristaltic pumps, gear pumps, piston pumps and other pump bodies to extract treatment agents to achieve automatic addition. In this way, an additional electric drive device needs to be set up, which increases the hardware cost and makes it difficult to widely promote and apply washing machines with automatic addition functions.

[0003] In the related technology, water flow can be used as a power source to drive the impeller, and the impeller drives the pump body to save costs. For example, a water wheel bin and a distribution bin are set on the delivery device, the impeller is set in the water wheel bin and transmits power to the transmission device in the distribution bin through the transmission shaft, and then the transmission device drives the pump body to operate to realize the automatic delivery of the treatment agent. In actual applications, if the water in the water wheel bin overflows into the distribution bin, the water overflowing into the distribution bin will often affect the power transmission of the transmission device in the distribution bin and even cause the transmission device to fail. Summary of the invention

[0004] In view of this, an embodiment of the present application provides a treatment agent delivery device and a washing device, aiming to improve the working reliability of the treatment agent delivery device driven by water flow.

[0005] The technical solution of the embodiment of the present application is implemented as follows:

[0006] On the one hand, an embodiment of the present application provides a treatment agent delivery device, comprising: a water wheel chamber, in which an impeller is provided for rotating under the drive of water flow; a distribution chamber; and a drainage structure located above the water wheel chamber, wherein the drainage structure is used to drain water overflowing upward from the water wheel chamber.

[0007] On the other hand, an embodiment of the present application provides a washing device, comprising the treatment agent delivery device as described above.

[0008] The technical solution provided in the embodiment of the present application is to provide a drainage structure above the water wheel bin, and the drainage structure is used to drain the water overflowing upward from the water wheel bin, so that the water in the water wheel bin that is not drained away in time can be directly drained by the drainage structure even if it overflows upward, thereby overcoming the problem that the water overflowing from the water wheel bin may affect the action of the transmission device in the distribution bin, and effectively avoiding the influence of sealing structures such as sealing rings on the power transmission of the transmission gear, so that the transmission gear can also effectively transmit torque under low water pressure conditions. In addition, it also effectively avoids the adverse influence of overflowing water on the operation of the transmission device in the distribution bin when the seal fails, thereby greatly improving the reliability of the operation of the treatment agent delivery device.

[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0028] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0029] In the related art, in order to prevent the water in the water wheel chamber from overflowing into the distribution chamber, a sealing ring is often set at the joint of the water wheel chamber and the distribution chamber, so as to prevent the water from overflowing into the distribution chamber while the transmission device outputs power. However, after the sealing ring is set, the resistance of the transmission device increases, resulting in the impeller being difficult to drive under low water pressure conditions, that is, the starting torque required for the treatment agent delivery device is large, and the impeller cannot work normally under low water pressure conditions, which greatly limits the application of the water flow driven treatment agent delivery device, and if the sealing ring fails, it will also affect the reliability of the treatment agent delivery device.

[0030] Based on this, in various embodiments of the present application, a drainage structure is formed above the water wheel bin, which can timely drain the water overflowing from the water wheel bin, thereby eliminating the need for sealing structures such as sealing rings, which can avoid the defect that the transmission device in the distribution bin is difficult to work under low water pressure after the resistance increases, and will not affect the transmission gear transmission due to overflow water caused by seal failure, thereby widening the water pressure working range and improving the reliability of the treatment agent delivery device. Since the treatment agent delivery device uses water flow as a power source, it eliminates the need for an electrically driven pump body, can also save costs, and has energy-saving and environmental protection effects.

[0031] The present application embodiment provides a treatment agent delivery device, such as Figures 1 to 6 As shown, the treatment agent delivery device comprises: a water wheel chamber 1A, a distribution chamber 1B and a drainage structure. The water wheel chamber 1A is provided with an impeller 2 for rotating under the drive of water flow, thereby converting water energy into mechanical energy. The distribution chamber 1B is at least partially located above the water wheel chamber 1A. The drainage structure is located above the water wheel chamber and is used to drain water overflowing upward from the water wheel chamber 1A.

[0032] In the embodiment of the present application, since a drainage structure is provided on the water wheel bin, the drainage structure can promptly drain the water overflowing upward from the water wheel bin 1A, so that the water in the water wheel bin 1A that is not promptly drained away can be directly drained away by the drainage structure even if it overflows upward, thereby overcoming the problem that the water overflowing from the water wheel bin 1A may affect the action of the transmission device in the distribution bin 1B, and effectively avoiding the influence of sealing structures such as sealing rings on the power transmission of the transmission gear 3, so that the transmission gear 3 can also effectively transmit torque under low water pressure conditions, and in addition, effectively avoiding the adverse influence of overflowing water on the operation of the transmission device in the distribution bin 1B when the seal fails, thereby greatly improving the reliability of the operation of the treatment agent delivery device.

[0033] Here, the drainage structure can be located inside the distribution bin 1B to drain the water overflowing into the distribution bin 1B in time. The drainage structure can also be arranged between the water wheel bin 1A and the distribution bin 1B, so that the water overflowing upward from the water wheel bin 1A can be drained by the drainage structure before entering the distribution bin 1B.

[0034] For example, Figures 3 to 6 As shown, the clothing treatment agent dispensing device also includes: a transmission rod 31, the first end 31A of the transmission rod is connected to the impeller 2, and is driven to rotate by the impeller 2, the second end 31B of the transmission rod 31 extends into the dispensing bin 1B, and a gear ring 312 is arranged outside the second end 31B of the transmission rod 31, and the gear ring 312 can drive the transmission device in the dispensing bin 1B to operate. It can be understood that the transmission rod 31 is arranged along the height direction of the water wheel bin 1A, and the upper wall of the water wheel bin 1A is provided with a through hole for the transmission rod 31 to pass through, so as to transmit the power output by the impeller 2 to the dispensing bin 1B. The water overflowing upward along the through hole in the water wheel bin 1A can be directly guided to the outside of the dispensing bin 1B by the drainage structure, so as to avoid interference with the transmission of the transmission device arranged in the dispensing bin 1B.

[0035] Compared with the design of setting sealing structures such as sealing rings to prevent water in the turbine bin 1A from overflowing into the distribution bin 1B, the embodiment of the present application adopts an actively designed drainage structure to timely drain the water that has not been discharged in time from the turbine bin 1A through the drainage structure. Based on the new design concept of the seal-free structure, it can not only avoid the problem that the transmission device is difficult to start under low water pressure due to the increased resistance caused by the sealing contact stress, but also effectively prevent the overflow water from affecting the transmission device in the distribution bin 1B, such as the transmission failure of the transmission device caused by the resistance of the water flow, so that the operating reliability of the treatment agent delivery device driven by the water flow is greatly improved.

[0036] In some embodiments, Figure 7As shown, the drainage structure includes: a water retaining ring 32, which is fixed on the transmission rod 31, and the water retaining ring 32 is located on the side of the gear ring 312 facing the water wheel chamber 1A, that is, the water retaining ring 32 is located below the gear ring 312. It can be understood that the water retaining ring 312 can be located in the distribution chamber 1B, and the water retaining ring 32 can also be set between the water wheel chamber 1A and the distribution chamber 1B. The water retaining ring 32 is used to prevent the water overflowing from the matching position of the transmission rod 31 and the upper wall of the water wheel chamber 1A from flowing upward to the gear ring 312. It can be understood that the upper wall of the water wheel chamber 1A is provided with a through hole for the transmission rod 31 to pass through, and the transmission rod 31 is in gap with the through hole. When the water pressure in the water wheel chamber 1A is relatively high, the water in the water wheel chamber 1A that has not been discharged in time can overflow upward through the gap between the through hole and the transmission rod 31. At this time, the transmission rod 31 can rotate under the drive of the impeller 2, and the water retaining ring 32 fixed on the transmission rod 31 can effectively prevent the water overflowing upward from overflowing onto the water retaining ring 32, so as to avoid the water overflowing upward from affecting the transmission device such as the gear. Specifically, the overflow path of the water overflowing upward in the water wheel chamber 1A is as follows: Figure 4 The path indicated by the arrow.

[0037] Exemplarily, the outer ring of the water retaining ring 32 has a downwardly bent retaining edge 321 to guide the overflowing water to flow downward along the retaining edge 321. By providing the downwardly bent retaining edge 321, the blocked water flow can be blocked and drained, so that the overflowing water flow can flow downward along the bottom end of the retaining edge 321.

[0038] For example, Figure 5 As shown, the drainage structure also includes: a water retaining rib 111, the water retaining rib 111 is located outside the water retaining ring 32, and a roughly annular water collecting groove 112 is formed between the water retaining rib 111 and the water retaining ring 32. The water collecting groove 112 collects water overflowing from the water wheel chamber 1A, thereby discharging the collected water outside the distribution chamber 1B. Exemplarily, the water retaining rib 111 can be an annular convex rib formed on the upper surface of the upper wall of the water wheel chamber.

[0039] For example, Figure 5 As shown, the drainage structure further includes: a drainage channel 113, the drainage channel 113 is connected to the water collecting tank 112, and drains the water collected by the water collecting tank 112 to the outside of the drainage structure. Figure 5 As shown, the guide channel 113 can be composed of guide ribs arranged on the upper surface of the upper wall of the turbine chamber, and the guide ribs drain the accumulated water in the water collecting tank 112.

[0040] Exemplarily, the treatment agent delivery device further includes: a water receiving tray (not shown in the figure), which is arranged under the distribution bin 1B and is used to receive water discharged from the drainage structure, that is, to receive water discharged from the outlet of the diversion channel 113.

[0041] In some embodiments, Figure 6As shown, the treatment agent delivery device further includes: a dispensing mechanism 5 and a speed reduction mechanism 4. The speed reduction mechanism 4 is disposed between the ring gear 312 and the dispensing mechanism 5, and is used to reduce the speed and torque increase of the power output by the ring gear 312 before transmitting it to the dispensing mechanism 5.

[0042] Since the water pressure of the water flow may fluctuate during use, in the embodiment of the present application, the power output by the ring gear 312 on the transmission rod 31 is transmitted to the distribution mechanism 5 after being decelerated and torque-increased by the reduction mechanism 4, which can effectively widen the working range of the water flow and water pressure, so that the water flow under the low water pressure state drives the power output by the impeller 2. After being transmitted through the transmission rod 31, it is decelerated and torque-increased by the reduction mechanism 4, thereby increasing the torque output by the distribution mechanism 5, which is conducive to expanding the working range of the water pressure.

[0043] Here, the reduction mechanism 4 may include, but is not limited to: a gear reducer, a worm gear reducer or a planetary reducer, as long as it can convert the power transmitted by the transmission rod 31 into a larger output torque, and this application does not make any specific limitations on this.

[0044] Exemplarily, the reduction ratio of the reduction mechanism 4 is 30 to 150: 1. Thus, the treatment agent delivery device can work normally within the water pressure range of 0.03 MPa to 1.0 MPa, so that the treatment agent delivery device has a wide range of application prospects, for example, it can be applied to household appliances such as washing machines or dishwashers.

[0045] Exemplarily, the reduction mechanism 4 may include one or more reduction gears to transmit the power of the transmission rod 31 to the dispensing mechanism 5 .

[0046] In some embodiments, the water receiving tray also receives the treatment agent delivered by the dispensing mechanism 5, and an outlet is provided on the water receiving tray for discharging the mixed water and treatment agent. In this way, the overflowing water and the delivered treatment agent can be delivered to the working chamber of the washing device through the outlet by the water receiving tray. It is understandable that in other embodiments, the water receiving tray can also only receive the water discharged by the drainage structure, and the water accumulated in the water receiving tray can be cleaned manually regularly, or an outlet for discharging the accumulated water can be provided on the water receiving tray.

[0047] In some embodiments, the treatment agent delivery device further comprises: a housing 1, in which a water wheel chamber 1A and a distribution chamber 1B are formed spaced apart from each other. Here, the water wheel chamber 1A has a water inlet 115 and a water outlet 116, and water supplied from an external water source enters the water wheel chamber 1A through the water inlet 115, and after driving the impeller 2 to rotate in the water wheel chamber 1A, the water is discharged through the water outlet 116. The distribution chamber 1B has a liquid inlet (not shown in the figure) for supplying the treatment agent to the delivery mechanism and a liquid outlet 114 for the delivery mechanism to output the treatment agent.

[0048] For example, Figure 1As shown, the shell 1 includes: a shell body 11, an upper cover body 12 and a lower cover body 13. The shell body 11 and the lower cover body 13 cooperate to form a water wheel chamber 1A, and the shell body 11 and the upper cover body 12 cooperate to form a distribution chamber 1B.

[0049] Exemplarily, the water wheel chamber 1A is generally formed into a cylindrical chamber. Figure 6 and Figure 8 As shown, the impeller 2 includes: a rotating body 21 and a first blade group and a second blade group arranged at intervals on the rotating body 21. A baffle 24 is arranged between the first blade group and the second blade group to separate the first blade group from the second blade group. The first blade group includes a plurality of first blades 22, the plurality of first blades 22 are located on the upper side of the baffle 24, and the plurality of first blades 22 are arranged along the circumference of the rotating body 21. The second blade group includes a plurality of second blades 23, the plurality of second blades 23 are located on the lower side of the baffle 24, and the plurality of second blades 23 are arranged along the circumference of the rotating body 21. Here, the first blade 22 and / or the second blade 23 can be a curved blade or a straight blade, wherein a straight blade refers to a blade whose surface is planar so as to rotate under the drive of the water flow; a curved blade refers to a blade whose surface is curved so that the blade has a set curvature, which is conducive to forming a rotating vortex, thereby improving the rotation efficiency.

[0050] In some embodiments, the first blade 22 and the second blade 23 are both curved blades, and the curvature direction of the first blade 22 is opposite to that of the second blade 23. Exemplarily, a water inlet 115 and a water outlet 116 are provided on the water wheel chamber 1A, and the water inlet 115 has a first inlet connected to the chamber where the first blade 22 is located and a second inlet connected to the chamber where the second blade 23 is located. For example, the first blade 22 is curved in a clockwise direction, which is conducive to the water flow entering the first inlet to apply counterclockwise pressure to the first blade 22, thereby driving the rotating body 21 to rotate counterclockwise. The second blade 23 is curved in a counterclockwise direction, which is conducive to the water flow entering the second inlet to apply clockwise pressure to the second blade 23, thereby driving the rotating body 21 to rotate clockwise. In this way, the double-sided blades of an impeller 2 can be used to efficiently rotate forward or reverse under the action of water flow, which is conducive to outputting torques in different directions through the rotating body 21.

[0051] It can be understood that the baffle 24 is located between the first blade group and the second blade group, and is used to separate the first blade 22 from the second blade 23, reduce the possibility of the water flow entering the first inlet exerting an effect on the second blade group, and reduce the possibility of the water flow entering the second inlet exerting an effect on the first blade group, thereby improving the conversion efficiency of hydrodynamics.

[0052] In some embodiments, a shaft connection hole structure 211 is provided at the center of the rotating body 21 , and the connection structure 311 provided at the first end 31A of the transmission rod 31 can cooperate with the shaft connection hole structure 211 on the rotating body 21 , thereby transmitting the power of the rotating body 21 to the transmission gear 3 .

[0053] For example, the rotating body 21 may be provided with a plurality of through holes 212. By providing the through holes 212, the weight of the rotating body 21 can be reduced, thereby facilitating the rotation of the rotating body 21 under the drive of the water flow. In addition, the through holes 212 can also prevent the water retained in the rotating body 21 from interfering with the rotation of the rotating body 21, thereby further improving the rotation efficiency of the rotating body 21.

[0054] In some embodiments, the first blade set, the second blade set, the rotor 21 and the baffle 24 are integrally formed, so that the impeller 2 is an integral structure, simplifying the assembly process. In other embodiments, the impeller 2 can also be assembled using a split structure.

[0055] Exemplarily, the dispensing mechanism 5 may include a pump body, which is at least one of a plunger pump, a vane pump, and a diaphragm pump. The pump body may be disposed in the dispensing bin 1B, the inlet of the pump body is connected to the liquid inlet, the outlet of the pump body is connected to the liquid outlet 114, and the input end of the pump body is connected to the output end of the reduction mechanism 4, so that the treatment agent introduced at the liquid inlet is pumped in under the drive of the torque output by the reduction mechanism 4, and the treatment agent is delivered to the working chamber of the washing device through the liquid outlet 114. It is understandable that the number of pump bodies may be one or two (such as Figure 6 As shown), when the number of pump bodies is two, a power distribution mechanism can be additionally provided to distribute the power output by the reduction mechanism 4 to the two pump bodies, and this application does not make any specific limitation on this.

[0056] It is understandable that the treatment agent can be in liquid, powder or solid form, and this application does not make any specific limitation on this.

[0057] The embodiment of the present application further provides a washing device, comprising the detergent dispensing device of the above embodiment. Based on the above detergent dispensing device, the washing device can utilize the water flow of the water channel to achieve automatic dispensing of the treatment agent.

[0058] In the embodiment of the present application, the washing device may be a washing machine or a dishwasher. Taking a washing machine as an example, the washing machine includes: a housing, a washing tub, and a water supply pipeline. The housing is also provided with a storage cavity for storing detergents. The water inlet 115 of the detergent delivery device is connected to the water inlet pipeline, the liquid inlet is connected to the storage cavity for storing detergents, and the water outlet 116 and the liquid outlet 114 can both be connected to the washing tub. In this way, the water flow of the water inlet 115 can be used as a power source to realize the automatic delivery of the treatment agent in the storage cavity.

[0059] It should be noted that the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

[0060] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
