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, so as to realize the automatic delivery of the treatment agent. In actual application, if the water in the water wheel bin overflows into the distribution bin, the water overflowing into the distribution bin will often affect the operation 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.

[0011] The overflow prevention structure is located on the side of the partition facing the distribution bin and is used to drain the water overflowing from the first overflow gap.
[0012] The embodiment of the present application also provides a washing device, including the treatment agent delivery device described in the embodiment of the present application.
[0013] The technical solution provided in the embodiment of the present application forms a first overflow gap at the joint of the transmission shaft and the partition, and an overflow prevention structure is arranged on the side of the partition facing the distribution bin. Therefore, even if the water in the turbine bin that is not discharged in time overflows from the first overflow gap into the distribution bin, it can be drained by the overflow prevention structure, thereby overcoming the problem that the water overflowing from the turbine bin may affect the operation 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 shaft, so that the transmission shaft can effectively transmit torque under low water pressure conditions. In addition, it also effectively avoids the adverse influence of the water overflowing from the turbine bin on the operation of the transmission device in the distribution bin, thereby greatly improving the reliability of the operation of the treatment agent delivery device.

[0037] 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 provided at the joint of the transmission shaft and the water wheel chamber, so as to prevent the water from overflowing into the distribution chamber while the transmission shaft outputs power. However, after the sealing ring is provided, the resistance of the transmission shaft increases, which makes it difficult to be driven by the impeller 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.
[0038] Based on this, in various embodiments of the present application, the transmission shaft forms a first overflow gap at the partition separating the water wheel bin and the distribution bin, and an overflow prevention structure is provided on the side of the partition facing the distribution bin, so that the water overflowing from the first overflow gap in the water wheel bin into the distribution bin can be drained away through the overflow prevention structure, thereby eliminating the need for sealing structures such as sealing rings, which can avoid the defect that the transmission shaft is difficult to work under low water pressure after the resistance increases, and prevent the overflow water caused by sealing failure from affecting the transmission of the transmission device in the distribution bin, 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 the power source, it eliminates the need for an electrically driven pump body, can save costs, and has energy-saving and environmental protection effects.
[0039] The present application embodiment provides a treatment agent delivery device, such as Figures 1 to 5 As shown, the treatment agent delivery device includes: a water wheel bin 101, a distribution bin 102, a partition 104, a transmission shaft 3, an anti-overflow structure 4 and a distribution mechanism 5. The water wheel bin 101 is provided with an impeller 2 for rotating under the drive of water flow. The distribution bin 102 is located below the water wheel bin 101, and the distribution mechanism 5 is arranged in the distribution bin 102. The partition 104 is arranged between the water wheel bin 101 and the distribution bin 102, and is used to separate the water wheel bin 101 and the distribution bin 102. The input end of the transmission shaft 3 is connected to the impeller 2, and the output end of the transmission shaft 3 extends into the distribution bin 102 after passing through the partition 104, and is used to transmit power to the distribution mechanism 5. The transmission shaft 3 and the partition 104 are clearance-matched to form a first overflow gap. The distribution mechanism 5 is used to deliver the treatment agent under the action of the power input by the transmission shaft 3. The overflow prevention structure 4 is located on the side of the partition 104 facing the distribution bin 102 and is used to drain the water overflowing from the first overflow gap so as to timely drain the water overflowing from the water wheel bin 101 to the distribution bin 102 .
[0040] It can be understood that since the first overflow gap is formed at the joint between the transmission shaft 3 and the partition 104, and the water overflowing from the first overflow gap can be drained away by the anti-overflow structure 4, the water in the turbine bin 101 that is not drained away in time can be directly drained away by the anti-overflow structure 4 even if it overflows from the first overflow gap into the distribution bin 102, thereby overcoming the problem that the water overflowing from the turbine bin 101 may affect the operation of the transmission device in the distribution bin 102, and effectively avoiding the influence of the sealing structure such as the sealing ring on the power transmission of the transmission shaft 3, so that the transmission shaft 3 can also effectively transmit torque under low water pressure. In addition, it also effectively avoids the adverse influence of the overflowing water on the operation of the transmission device in the distribution bin 102 when the seal fails, thereby greatly improving the reliability of the operation of the treatment agent delivery device.
[0041] Compared with the design of setting sealing structures such as sealing rings to prevent water in the turbine bin 101 from overflowing into the distribution bin 102, the embodiment of the present application adopts an actively designed overflow gap to discharge the water that has not been discharged in time in the turbine bin 101 through the aforementioned first overflow gap and anti-overflow structure 4 in time. Based on the new design concept of the seal-free structure, it can not only avoid the problem that the transmission shaft 3 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 102, 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 water flow is greatly improved.
[0042] Exemplarily, the treatment agent delivery device comprises: a housing 1, the interior of the housing 1 is partitioned by a partition 104 to form a water wheel chamber 101 and a distribution chamber 102. Figure 1 As shown, the shell 1 can be roughly cylindrical, and the first end cover 103 is provided at the upper end of the shell 1, and the second end cover 109 is provided at the lower end of the shell 1. The partition 104 can be integrally formed with the shell 1 or separately formed. The partition 104 divides the inner cavity of the shell 1 into a water wheel chamber 101 located at the upper part and a distribution chamber 102 located at the lower part. The water wheel chamber 101 can have a water inlet 105 and a water outlet 106, so that water from an external water source (for example, tap water) can enter the water wheel chamber 101 and drive the internal impeller 2 to rotate, thereby converting the kinetic energy of the water into mechanical energy output. The power output by the impeller 2 is transmitted to the anti-overflow structure 4, and the distribution mechanism 5 is driven by the anti-overflow structure 4. The distribution chamber 102 can have a liquid inlet 107 for supplying the treatment agent to the distribution mechanism 5 and a liquid outlet 108 for the distribution mechanism 5 to output the treatment agent. The distribution mechanism 5 realizes the automatic delivery of the treatment agent under the drive of the anti-overflow structure 4.
[0043] Exemplarily, the water wheel chamber 101 is roughly circular, and the impeller 2 includes a wheel disc body 201 and a plurality of blades 202 arranged on the outer peripheral surface of the wheel disc body 201, and the axial direction of the wheel disc body 201 is perpendicular to the plane where the water wheel chamber 101 is located. The water inlet 105 and the water outlet 106 can be respectively arranged on both sides of the impeller 2, and the water flow is suitable for driving the impeller 2 to rotate after entering through the water inlet 105; the wheel disc body 201 of the impeller 2 is connected to the input end of the transmission shaft 3. In this way, the impeller 2 can rotate under the drive of the water flow, thereby converting the water energy into mechanical energy. Here, the blade 202 can be a curved blade or a straight blade, wherein the straight blade means that the surface of the blade 202 is flat, so as to rotate under the drive of the water flow; the curved blade means that the surface of the blade 202 is curved, so that the blade 202 has a set curvature, which is conducive to the formation of a rotating vortex.
[0044] For example, Figure 3 and Figure 5As shown, the rotating shaft of the impeller 2 (i.e., the wheel body 201) is arranged along the height direction of the water wheel chamber 101, and the middle part of the partition 104 has a convex portion 1042 protruding upward, and the partition 104 is provided with a first through hole 1043 for the transmission shaft 3 to pass through at the convex portion 1042. The diameter of the first through hole 1043 is larger than the outer diameter of the transmission shaft 3, and a first overflow gap is formed between the transmission shaft 3 and the partition 104.
[0045] For example, the end surface 1041 of the partition 104 facing the water wheel chamber 101 is high in the middle and low around. In this way, the water flow in the water wheel chamber 101 can be discharged from the water outlet 106 in time under the guidance of the end surface 1041. Figure 3 As shown, the water outlet 106 can be arranged at the side wall of the water wheel chamber 101. A small amount of water not discharged from the water outlet 106 can be guided into the distribution chamber 102 along the outer wall of the transmission shaft 3 through the first overflow gap formed between the transmission shaft 3 and the partition 104.
[0046] For example, Figure 6 and Figure 7 As shown, the overflow prevention structure 4 has a first branch 401 close to the partition 104 and a second branch 402 away from the partition 104. The first branch 401 defines a second through hole 4011 for the transmission shaft 3 to pass through. The diameter of the second through hole 4011 is larger than the outer diameter of the transmission shaft 3, so that a second overflow gap for drainage is formed between the transmission shaft 3 and the inner wall surface of the overflow prevention structure 4. The first overflow gap is connected to the second overflow gap, so that the second overflow gap can drain water overflowing from the first overflow gap.
[0047] Exemplarily, the outer wall surface of the first branch 401 is provided with a plurality of external teeth 4012 along the circumferential direction, and a reduction mechanism 6 for reducing speed and increasing torque is provided in the distribution bin 102, the input end of the reduction mechanism 6 is meshedly connected with the external teeth 4012 of the first branch 401, and the output end of the reduction mechanism 6 is connected to the distribution mechanism 5.
[0048] Since the water pressure of the water flow may fluctuate during use, in the embodiment of the present application, the power output by the impeller 2 is transmitted to the anti-overflow structure 4 via the transmission shaft 3, and the power output by the anti-overflow structure 4 is decelerated and torque-increased by the speed reduction mechanism 6 and then transmitted to the distribution mechanism 5, which can effectively widen the working range of the water flow and water pressure, so that the water flow under low water pressure drives the power output by the impeller 2, which is transmitted through the transmission shaft 3 and the anti-overflow structure 4, and then decelerated and torque-increased by the speed reduction mechanism 6, thereby increasing the torque output by the distribution mechanism 5, which is conducive to expanding the working range of the water pressure.
[0049] Here, the reduction mechanism 6 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 anti-overflow structure 4 into a larger output torque, and this application does not make any specific limitations on this.
[0050] Exemplarily, the reduction ratio of the reduction mechanism 6 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.
[0051] Exemplarily, the reduction mechanism 6 includes: planetary gears, a planetary carrier and a ring gear. The planetary gears are located between the anti-overflow structure 4 and the ring gear. The planetary gears are meshed with the outer teeth 4012 of the anti-overflow structure 4 and the inner tooth surface of the ring gear. The planetary carrier is connected to the planetary gears, and outputs power to the distribution mechanism 5 under the drive of the planetary gears. It can be understood that the anti-overflow structure 4 serves as the sun gear of the planetary reducer. The planetary carrier serves as the output end of the planetary reducer to drive the distribution mechanism 5 to operate. Here, the ring gear can be a separately arranged annular member, and the inner wall of the annular member is provided with internal teeth. The annular member is fixed in the distribution bin 102, or a ring gear with an annular inner tooth surface is formed on the inner wall of the distribution bin 102. This application does not make specific limitations on this.
[0052] For example, Figure 5 As shown, the distribution chamber 102 is separated into a deceleration chamber 102A for accommodating the deceleration mechanism 6 and a delivery chamber 102B for accommodating the distribution mechanism 5. The delivery chamber 102B has a liquid inlet 107 for supplying the treatment agent to the distribution mechanism 5 and a liquid outlet 108 for the distribution mechanism 5 to output the treatment agent. In this way, the deceleration mechanism 6 and the distribution mechanism 5 have independent chambers.
[0053] Since the overflow prevention structure 4 needs to transmit the power output by the transmission shaft 3, the overflow prevention structure 4 needs to be fixedly connected to the transmission shaft 3. Exemplarily, the second branch 402 is provided with a third through hole 4021 for the transmission shaft 3 to pass through, and the transmission shaft 3 is interference-fitted with the third through hole 4021, thereby realizing a fixed connection between the overflow prevention structure 4 and the transmission shaft 3. It is understandable that, in other embodiments, the overflow prevention structure 4 and the transmission shaft 3 can be connected by other means such as pin connection and clamping.
[0054] Exemplarily, the first through hole 1043, the second through hole 4011 and the third through hole 4021 are coaxial. In this way, the first overflow gap and the second overflow gap are arranged opposite to each other, so that the second overflow gap can drain the water flowing out of the first overflow gap.
[0055] Exemplarily, the second branch 402 is further provided with a guide channel 4022 communicating with the second overflow gap. The guide channel 4022 can guide the water entering the second overflow gap to the bottom end of the second branch 402.
[0056] It can be understood that water overflowing from the first overflow gap in the water wheel bin 101 can be guided to the second overflow gap along the outer wall of the transmission shaft 3, so that the water entering the distribution bin 102 can be discharged in time to avoid interference with the transmission of the transmission device in the distribution bin 102.
[0057] Exemplarily, the first branch 401 of the overflow prevention structure 4 may be close to or abut against the lower end surface of the partition 104, so that water overflowing from the first overflow gap may be directly absorbed by the second overflow gap.
[0058] For example, Figure 5 As shown, the middle part of the lower end surface of the partition 104 has a protruding structure 1044 protruding downward, the bottom end of the protruding structure 1044 forms the bottom end surface of the first through hole 1043, and the diameter of the second through hole 4011 is larger than the outer diameter of the protruding structure 1044. In this way, the water overflowing from the water wheel bin 101 is guided into the distribution bin 102 along the gap between the outer wall of the transmission shaft 3 and the first through hole 1043. Since the diameter of the second through hole 4011 is larger than the outer diameter of the protruding structure 1044, the first through hole 1043 can be partially extended into the second through hole 4011, so as to better drain the water overflowing into the distribution bin.
[0059] 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 102, the inlet of the pump body is connected to the liquid inlet 107, the outlet of the pump body is connected to the liquid outlet 108, and the input end of the pump body is connected to the output end of the reduction mechanism 6, so that the treatment agent introduced at the liquid inlet 107 is pumped in under the drive of the torque output by the reduction mechanism 6, and the treatment agent is delivered into the working chamber of the washing device through the liquid outlet 108. It is understandable that the number of pump bodies may be one or two. When the number of pump bodies is two, a power distribution mechanism may be added to distribute the power output by the reduction mechanism 6 to the two pump bodies, and this application does not make specific limitations on this.
[0060] For example, Figure 5 As shown, the dispensing mechanism 5 includes: a rotating member 502, the rotating member 502 is arranged opposite to the overflow prevention structure 4, and the rotating member 502 is provided with a drainage hole 5021 along the axial direction for guiding the water discharged from the overflow prevention structure 4 to the outside of the dispensing bin 102. Specifically, the second end cover 109 is arranged at the bottom end of the dispensing bin 102, and the rotating member 502 of the dispensing mechanism 5 can rotate relative to the second end cover 109. For example, a recess is arranged in the middle of the second end cover 109, and the rotating member 502 is rotatably arranged at the recess, and the second end cover 109 is provided with an overflow port 1091 at the recess, so that the water discharged from the guide channel 4022 on the overflow prevention structure 4 can be discharged to the outside of the dispensing bin 102 through the drainage hole 5021 and the overflow port 1091 on the rotating member 502.
[0061] Exemplarily, the dispensing mechanism 5 further includes: a partition 501, which divides the dispensing mechanism 5 into at least two dispensing areas spaced apart from each other. The partition 501 is fixed to the rotating member 502, for example, integrally formed with the rotating member 502, or fixed to the rotating member 502 by fasteners. The rotating member 502 of the dispensing mechanism 5, driven by the speed reduction mechanism 6, drives each dispensing area to automatically dispense the treatment agent, and can be compatible with the dispensing of liquid, powdered and solid treatment agents, and has a wide range of applications.
[0062] Exemplarily, the number of the partitions 501 can be multiple, so as to divide the dispensing mechanism 5 into multiple mutually spaced dispensing areas, and each dispensing area can include: a notch. The notch is suitable for the treatment agent to enter the mutually spaced dispensing areas. When the dispensing area is rotated to the delivery position, the treatment agent in the dispensing area can be delivered to the delivery channel.
[0063] Exemplarily, the treatment agent delivery device further includes: a water receiving tray 7, which is arranged below the distribution bin 102 and is used to receive water discharged from the distribution bin 102. In this way, the water receiving tray 7 can collect the water discharged from the distribution bin 102 to avoid affecting the interior of the washing device.
[0064] Exemplarily, the water receiving tray 7 is provided with an opening (not shown in the figure) for discharging the collected water. Figure 3 and Figure 4 As shown by the arrow in the figure, a small amount of water in the water wheel chamber 101 that has not been discharged from the water outlet 106 in time can be guided by the first overflow gap at the center to penetrate downward under the guidance of the transmission shaft 3, flow along the transmission shaft 3 into the second overflow gap formed between the transmission shaft 3 and the second through hole 4011, and then be guided by the guide channel 4022 to the drainage hole 5021 of the rotating member 502, and flow to the water receiving tray 7 through the overflow port 1091 on the second end cover 109. The treatment agent discharged by the dispensing mechanism 5 can also be discharged to the water receiving tray 7 from the liquid outlet 108. The overflow water and the treatment agent can be mixed at the water receiving tray 7, and then discharged to the delivery channel through the opening of the water receiving tray 7, so as to be delivered into the working chamber of the washing device.
[0065] 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.
[0066] 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 105 of the detergent delivery device is connected to the water inlet pipeline, the liquid inlet 107 is connected to the storage cavity for storing detergents, and the water outlet 106 and the liquid outlet 108 can both be connected to the washing tub. In this way, the water flow of the water inlet 105 can be used as a power source to realize the automatic delivery of the treatment agent in the storage cavity.
[0067] It should be noted that the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.
[0068] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto.
