Abstract
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] In the related art, washing equipment often needs to add treatment agents during the washing process. Taking washing machines as an example, it is necessary to add treatment agents such as laundry detergent and softener. 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 for washing machines with automatic addition functions to be widely promoted and applied.

[0054] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.
[0055] In the description of the present application, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.
[0056] In the description of the present application, the terms "first, second" and the like are only used to distinguish similar objects and do not represent a specific order of the objects. It is understandable that "first, second" and the like can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. Unless otherwise specified, "plurality" means at least two.
[0057] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0058] 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. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0059] 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. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0060] The present application provides a treatment agent delivery device, which can use water flow as a power source to achieve automatic delivery of the treatment agent. Figures 1 to 7As shown, the treatment agent delivery device includes: a first chamber 1A, a rotating mechanism 2, a dispensing mechanism 3 and a metering unit. Among them, the first chamber 1A has a water inlet 1011. The rotating mechanism 2 is arranged in the first chamber 1A, and is used to rotate under the drive of the water flow entering the water inlet. The input end of the speed reduction mechanism 4 is connected to the rotating mechanism 2, and the dispensing mechanism 3 is connected to the output end of the speed reduction mechanism 4, which is used to deliver the treatment agent. The rotating mechanism 2 rotates under the drive of the water flow introduced by the water inlet 1011, and the power output by the rotating mechanism 2 is transmitted to the dispensing mechanism 3 after being decelerated and torque-increased by the speed reduction mechanism 4. The dispensing mechanism 3 controls the delivery of the treatment agent under the drive of the speed reduction mechanism 4. In this way, the water flow can be used as a power source to realize the automatic delivery of the treatment agent, and the electric drive device can be omitted, thereby saving costs.
[0061] Here, the metering unit can detect the action of the rotating mechanism 2 or the dispensing mechanism 3 or the speed reduction mechanism 4 to meter the amount of the treatment agent to be added.
[0062] In some embodiments, the metering unit includes: an inductive switch 5 arranged at the rotating mechanism 2, the deceleration mechanism 4 or the dispensing mechanism 3, and the inductive switch 5 can detect the number of rotations of the corresponding mechanism or the number of reciprocating movements. For example, when the inductive switch 5 is arranged at the rotating mechanism 2, the inductive switch 5 can detect the number of rotations of the rotating mechanism 2. When the inductive switch 5 is arranged at the deceleration mechanism 4, the inductive switch 5 can detect the number of rotations of the deceleration mechanism 4. When the inductive switch 5 is arranged at the dispensing mechanism 3, the inductive switch 5 can detect the number of rotations of the dispensing mechanism 3 or the number of reciprocating movements. Specifically, if the dispensing mechanism 3 is an actuator for circumferential motion, the inductive switch 5 detects the number of rotations of the actuator, and if the dispensing mechanism 3 is an actuator for reciprocating motion, the inductive switch 5 detects the number of reciprocating movements of the actuator. For example, if the dispensing mechanism 3 is a plunger pump, the inductive switch 5 can detect the number of movements of the plunger pump, so as to meter the amount of treatment agent.
[0063] It can be understood that the dispensing mechanism 3 is used to dispense the treatment agent, and the induction switch 5 is arranged at the dispensing mechanism 3. By detecting the number of rotations of the dispensing mechanism 3 or the number of reciprocating motions, the number of times the treatment agent is dispensed can be directly reflected, so that the amount of treatment agent dispensed can be reasonably determined based on the single set dispensing capacity and the number of dispensing times.
[0064] It can be understood that since the reduction mechanism 4 has a certain reduction ratio, by detecting the number of rotations of the reduction mechanism 4 or the number of rotations of the rotating mechanism 2, based on the corresponding reduction ratio and the detected number of rotations, the number of times the treatment agent is dosed can also be indirectly determined, thereby the amount of treatment agent dosed can be reasonably determined based on the single set dose capacity and number of doses.
[0065] Preferably, the induction switch 5 is arranged at the dispensing mechanism 3, which can directly detect the number of times the treatment agent is dosed, avoiding the process of calculating the number of times the treatment agent is dosed based on the reduction ratio conversion, and the rotation speed of the rotating mechanism 2 is transmitted to the dispensing mechanism 3 after being decelerated and torque-increased by the reduction mechanism. Compared with the speed mechanism 2, the frequency of rotation or reciprocating motion of the dispensing mechanism 3 will be effectively reduced, which is more conducive to the detection of the induction switch and the accurate measurement of the amount of treatment agent dosed.
[0066] In some embodiments, the metering unit further includes: a controller (not shown in the figure), connected to the induction switch 5, and used to determine the amount of the treatment agent to be delivered based on the output signal of the induction switch 5. Here, the controller can pre-configure the value of the delivery capacity of the dispensing mechanism 3 for a single delivery, and determine the number of deliveries of the dispensing mechanism 3 directly or through a conversion operation based on the output signal of the induction switch 5, and determine the delivery amount of the treatment agent based on the delivery capacity and the delivery number, thereby achieving accurate metering of the delivery of the treatment agent. Here, the controller can be a separately arranged processor, or it can share a controller such as a computer control board of the washing equipment, and this application does not make specific restrictions on this. Exemplarily, when the delivery amount of the treatment agent reaches a set amount, the controller can control the water inlet valve at the water inlet 1011 to close and stop water inlet, so that the dispensing mechanism 3 stops delivering the treatment agent, thereby achieving automatic and accurate delivery of the treatment agent.
[0067] Here, the induction switch 5 can be at least one of a mechanical micro switch and a non-contact induction switch. Among them, the mechanical micro switch performs detection based on a contact method. The non-contact induction switch can perform detection based on a non-contact method, for example, it can be in the form of infrared induction, magnetic induction, ultrasonic wave, Hall switch, etc., which is not specifically limited in this application.
[0068] In an application example, the inductive switch 5 is a mechanical micro switch, and the mechanical micro switch is set at the dispensing mechanism 3 as an example for explanation. The dispensing mechanism 3 is provided with a touch piece for touching the inductive switch 5. During the rotation or reciprocating motion of the dispensing mechanism 3, the touch piece will touch the mechanical micro switch near the dispensing mechanism 3, so that the mechanical micro switch outputs an electrical signal to the controller, so that the controller can measure the number of rotations or reciprocating motions of the dispensing mechanism 3. For the case where the mechanical micro switch is set at the rotating mechanism 2 or the speed reduction mechanism 4, the above design can be referred to and will not be repeated here.
[0069] In an application example, the inductive switch 5 is a Hall switch, and the Hall switch is set at the dispensing mechanism 3 as an example for explanation. A follow-up magnet can be set on the dispensing mechanism 3. During the rotation or reciprocating motion of the dispensing mechanism 3, when the magnet is opposite to the nearby Hall switch, the Hall switch outputs an electrical signal to the controller, so that the controller can measure the number of rotations or reciprocating motions of the dispensing mechanism 3. For the case where the Hall switch is set at the rotating mechanism 2 or the speed reduction mechanism 4, the above design can be referred to and will not be repeated here.
[0070] It should be noted that, since the water pressure of the water flow may fluctuate during use, in the embodiment of the present application, the output power of the rotating mechanism 2 is transmitted to the dispensing mechanism 3 after being decelerated and torque-increased by the speed reduction mechanism 4, which can effectively widen the working range of the water flow pressure, so that after the water flow under low water pressure drives the rotating mechanism 2, the speed reduction mechanism 4 decelerates and increases the torque, thereby increasing the torque output by the dispensing mechanism 3, so that the dispensing mechanism 3 can operate effectively, thereby realizing the automatic delivery of the treatment agent, which is beneficial to improving the reliability of the treatment agent delivery device.
[0071] It is understandable that the rotating mechanism 2 can be an impeller driven by water flow, such as a turbine or a propeller. As long as the rotating mechanism 2 can rotate and output power under the action of the water flow passing through the first chamber 1A, this application does not make any specific restrictions on this.
[0072] For example, Figure 2 As shown, the first chamber 1A is roughly formed as a cylindrical chamber, and the first side of the first chamber 1A extends outward to form an inlet pipe 1016 and an outlet pipe 1017. The inlet of the inlet pipe 1016 forms a water inlet 1011, and the outlet of the outlet pipe 1017 forms a water outlet 1012; water flows in from the water inlet 1011, thereby driving the rotating mechanism 2 to rotate.
[0073] In some embodiments, Figure 1 and Figure 2 As shown, the rotating mechanism 2 includes an impeller 21, and the rotating shaft 211 of the impeller 21 is arranged in the first chamber 1A, and the water inlet 1011 and the water outlet 1012 are respectively arranged on both sides of the impeller 21. After the water flows in through the water inlet 1011, it is suitable for driving the impeller 21 to rotate; the rotating shaft 211 of the impeller 21 is connected to the input end of the reduction mechanism 4. In this way, the impeller 21 can rotate under the drive of the water flow, thereby converting the water energy into mechanical energy. Here, the impeller 21 includes a plurality of blades 212 fixed on the rotating shaft 211, and the blades 212 can be curved blades or straight blades, wherein the straight blade refers to the surface of the blade being planar, so as to rotate under the drive of the water flow; the curved blade refers to the surface of the blade being curved, so that the blade has a set curvature, which is conducive to the formation of a rotating vortex.
[0074] For example, Figure 1 and Figure 2 As shown, the water inlet 1011 and the water outlet 1012 are respectively arranged on both sides of the housing 101, and the external water source enters the first chamber 1A through the water inlet 1011, flows out through the water outlet 1012, and drives the rotating mechanism 2 to rotate. Figure 2 As shown by the arrow, the rotating mechanism 2 in the first chamber 1A rotates clockwise under the pressure of the water flow. In other embodiments, the water inlet 1011 can also be arranged vertically with the water outlet 1012. The present application does not specifically limit the arrangement positions of the water inlet 1011 and the water outlet 1012.
[0075] For example, Figure 1 As shown, the treatment agent delivery device includes: a shell 1, in which a first chamber 1A and a second chamber 1C are formed and spaced from each other. The shell 1 includes an outer shell 101, a first end cover 102 and a second end cover 103. The first end cover 102 cooperates with the outer shell 101 to form the first chamber 1A, and the second end cover 103 cooperates with the outer shell 101 to form the second chamber 1C. The water inlet 1011 and the water outlet 1012 are respectively arranged on both sides of the outer shell 101. The external water source enters the first chamber 1A through the water inlet 1011, flows out through the water outlet 1012, and drives the rotating mechanism 2 to rotate. For example, the direction of the water flow is along Figure 2 As shown by the arrow, the impeller 21 located in the first chamber 1A rotates in the clockwise direction under the pressure of the water flow.
[0076] It is understandable that 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 output by the water flow-driven rotating mechanism 2 into a larger output torque, and this application does not make specific limitations on this.
[0077] In some embodiments, a third chamber 1B for accommodating the speed reduction mechanism 4 is formed in the housing 101, and the third chamber 1B is located between the first chamber 1A and the second chamber 1C. It is understood that in other embodiments, the speed reduction mechanism 4 can also be disposed in the second chamber 1C, thereby making the structure more compact.
[0078] For example, Figure 1 The first chamber 1A, the third chamber 1B, and the second chamber 1C are arranged in sequence along the height direction of the treatment agent delivery device. It can be understood that the first chamber 1A, the third chamber 1B, and the second chamber 1C can also be arranged in sequence along the horizontal direction. Those skilled in the art can reasonably design the number and arrangement orientation of the chambers according to the installation space, and this application does not make specific limitations on this.
[0079] For example, Figure 1 and Figure 3As shown, the reduction mechanism 4 includes: a power shaft 401, a planetary gear 402, a planetary carrier 403 and a ring gear 404, wherein the power shaft 401 is connected to the rotating mechanism 2 and driven by the rotating mechanism 2; the ring gear 404 is fixed on the housing 101, and it can be understood that the ring gear 404 can be a separately arranged annular member, and the inner wall of the annular member is provided with internal teeth, and the annular member is fixed in the third chamber 1B, or the ring gear 404 with an annular inner tooth surface is machined on the inner wall of the third chamber 1B; the planetary gear 402 is arranged between the power shaft 401 and the ring gear 404, and is meshed with the power shaft 401 and the ring gear 404; the planetary carrier 403 is connected to the planetary gear 402, and outputs power to the distribution mechanism 3 under the drive of the planetary gear 402. It can be understood that the first end 401A of the power shaft 401 can extend into the first chamber 1A and be fixedly connected to the rotating mechanism 2, and the second end 401B of the power shaft 401 is provided with external teeth meshing with the planetary gear 402, serving as the sun gear of the planetary reducer. The planet carrier 403 can have an end 403A extending into the second chamber 1C, and the end 403A is used to drive the dispensing mechanism 3 located in the second chamber 1C.
[0080] In some embodiments, Figure 4 As shown, the speed reduction mechanism 4 includes: a power shaft 401, a first speed reduction gear 405, a second speed reduction gear 406 and an output shaft 407. The first speed reduction gear 405 has a large end face meshing with the power shaft 401 and a small end face for meshing with the second speed reduction gear 406. The power shaft 401 is driven by the rotating mechanism 2, and the power shaft 401 cooperates with the large end face of the first speed reduction gear 405 to achieve speed reduction; the small end face of the first speed reduction gear 405 cooperates with the second speed reduction gear 406 to achieve speed reduction again; the second speed reduction gear 406 is connected to the output shaft 407, so that after step-by-step speed reduction, the power of the water flow can be transmitted to the distribution mechanism 3 located in the second chamber 1C through the output shaft 407. It can be understood that the number of speed reduction gears arranged between the power shaft 401 and the output shaft 407 can be set according to demand to meet the demand of the speed reduction ratio.
[0081] In some embodiments, 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.
[0082] For example, Figure 5 As shown, the dispensing mechanism 3 includes: a partition 302, and the partition 302 divides the dispensing mechanism 3 into at least two dispensing areas spaced apart from each other.
[0083] The water flow entering from the water inlet 1011 drives the rotating mechanism 2, and the power output by the rotating mechanism 2 is amplified after being decelerated and torque-increased by the speed reduction mechanism 4, and the amplified power drives the partition 302 to rotate, thereby realizing automatic delivery of the treatment agent, and the electric drive device can be omitted, thereby saving costs, and the dispensing mechanism 3 is suitable for the delivery of liquid, powdered and solid treatment agents, and has a wide range of applications; in addition, the output power of the rotating mechanism 2 is transmitted to the dispensing mechanism 3 after being decelerated and torque-increased by the speed reduction mechanism 4, which can effectively widen the working range of the water flow and water pressure and improve the reliability of the treatment agent delivery device.
[0084] Here, the number of the partitions 302 can be multiple, so as to divide the dispensing mechanism 3 into multiple mutually spaced dispensing areas, and each dispensing area can include: a notch 303. The notch 303 is suitable for the treatment agent to enter the mutually spaced dispensing areas. When the dispensing area rotates to the delivery position, the treatment agent in the dispensing area can be delivered to the delivery channel.
[0085] In some embodiments, Figure 1 and Figure 5 As shown, the dispensing mechanism 3 is arranged in the second chamber 1C, and the dispensing mechanism 3 includes a rotating member 301, and the rotating member 301 is connected to the output end of the speed reduction mechanism 4; the partition 302 is connected to the rotating member 301; the partition 302 includes: a straight segment 3022 extending along the radial direction of the rotating member 301 to the inner wall surface of the second chamber 1C and an arc segment 3021 abutting against the inner wall surface of the second chamber 1C; a gap 303 is formed between the arc segment 3021 and the straight segment 3022 of the adjacent partition 302. Here, the partition 302 divides the area where the dispensing mechanism 3 is located into at least two mutually spaced dispensing areas, and under the rotation of the dispensing mechanism 3, each dispensing area can be sequentially charged with a treatment agent. Here, the treatment agent can be a liquid, powdered or solid washing product such as laundry beads required for washing. Those skilled in the art can make a reasonable choice according to needs, and this application does not make specific restrictions on this.
[0086] For example, Figure 5 As shown, four partitions 302 are symmetrically arranged around the rotating member 301 to divide the second chamber 1C into four mutually isolated areas, so that the capacity of the treatment agent in each area (equivalent to the bin) is fixed, so that when the rotating member 301 rotates under the power output by the reduction mechanism 4, a certain amount of treatment agent in each area is driven to the liquid outlet 1014 and is released into the corresponding pipeline or container under the action of gravity.
[0087] Exemplarily, the induction switch 5 is disposed on the inner wall of the second chamber 1C, and is used to sense the number of rotations of the rotating member 301. During the rotation of the rotating member 301, the induction switch 5 outputs an electrical signal to the controller based on the rotation of the rotating member 301. The controller can calculate whether the amount of treatment agent delivered meets the preset value based on the electrical signal fed back by the induction switch 5. When the delivery amount meets the preset value, the water inlet valve of the water inlet is controlled to be closed, so that the treatment agent delivery device stops working, and the process of precise automatic delivery is completed. For example, the induction switch 5 can be the aforementioned mechanical micro switch, and a touch member for touching the mechanical micro switch is disposed on any partition 302. When the rotating member 301 rotates one circle, the touch member touches the mechanical micro switch once, and the mechanical micro switch outputs an electrical signal. The controller can count the number of rotations of the rotating member 301 based on the electrical signal output by the mechanical micro switch. For another example, the induction switch 5 can be the aforementioned Hall switch. A magnet is set on any partition 302. When the rotating member 301 rotates one circle, the Hall switch outputs an electrical signal when it is facing the magnet. The controller can count the number of rotations of the rotating member 301 based on the electrical signal output by the Hall switch.
[0088] The working process of the treatment agent delivery device of the embodiment of the present application is introduced below:
[0089] The external water flows into the first chamber 1A through the water inlet 1011 and flows out from the water outlet 1012. The impeller 21 rotates driven by the water flow. The rotational kinetic energy generated by the rotation of the impeller 21 is transmitted to the speed reduction mechanism 4 through the power shaft 401, and the speed reduction mechanism 4 drives the rotating member 301 of the distribution mechanism 3 after the speed reduction and torque increase. Here, due to the speed reduction and torque increase of the speed reduction mechanism 4, the torque output by the impeller 21 is increased, and the rotating member 301 can be driven to rotate normally within a wider water pressure range (such as Figure 5 The controller 301 is used to control the amount of treatment agent delivered to the liquid outlet 1014, and then the amount of treatment agent delivered to the corresponding pipeline or container is automatically delivered. During the delivery process, the controller can calculate whether the amount of treatment agent delivered meets the preset value based on the electrical signal fed back by the induction switch 5. When the amount of delivery meets the preset value, the water inlet valve of the water inlet is controlled to be closed, so that the treatment agent delivery device stops working, and the process of precise and automatic delivery is completed. The dispensing mechanism 3 is not only suitable for the automatic delivery of liquid treatment agents, but also for the automatic delivery of solid treatment agents such as washing powder and washing beads.
[0090] In some embodiments, the dispensing mechanism 3 may also use a pump body, such as at least one of a plunger pump, a vane pump, and a diaphragm pump. The pump body can work under the power of the torque increase output by the speed reduction mechanism 4. For example, the input shaft of the pump body can be connected to Figure 1The end 403A of the planet carrier 403 or Figure 4 The output shaft 407 is shown. It is understandable that the induction switch 5 can detect the number of pump actions, so that the controller can determine whether the amount of treatment agent delivered meets the preset value based on the statistical number of pump actions, thereby achieving accurate delivery of the treatment agent.
[0091] Take the plunger pump as an example. Figure 6 and Figure 7 As shown, the dispensing mechanism 3 may include: a pump housing 304, a first one-way valve 305, a second one-way valve 306 and a crank slider mechanism 308, wherein a pump cavity 307 is formed in the pump housing 304, the pump cavity 307 is connected to the liquid inlet 1013 via the first one-way valve 305, and the treatment agent or water can enter the pump cavity 307 unidirectionally through the liquid inlet 1013 and the first one-way valve 305; the pump cavity 307 is connected to the liquid outlet 1014 via the second one-way valve 306, and the treatment agent or water in the pump cavity 307 can be discharged unidirectionally through the second one-way valve 306 and the liquid outlet 1014. The crank slider mechanism 308 can convert the circumferential motion into a linear reciprocating motion under the drive of the output end of the speed reduction mechanism 4, so that the slider matched with the pump cavity 307 moves back and forth along the inner wall surface of the pump cavity 307, so as to drive the treatment agent or water to enter through the liquid inlet 1013 and the first one-way valve 305 in one direction, and to be discharged through the second one-way valve 306 and the liquid outlet 1014 in one direction. Here, the induction switch 5 can detect the number of actions of the crank slider mechanism 308, so that the controller can determine whether the amount of treatment agent delivered meets the preset value based on the statistical number of actions, thereby realizing the precise delivery of the treatment agent. Among them, the crank slider mechanism 308 refers to a planar connecting rod mechanism that uses a crank and a slider to realize the mutual conversion between rotation and movement, and the specific structure is not repeated here.
[0092] The present application also provides a washing device, comprising the treatment agent delivery device of the above embodiment. Based on the above treatment agent delivery device, the washing device can utilize the water flow of the waterway to achieve automatic delivery of the treatment agent.
[0093] 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 chamber for storing the treatment agent. The water inlet 1011 of the treatment agent delivery device is connected to the water inlet pipeline, the liquid inlet 1013 is connected to the storage chamber for storing the treatment agent, and the water outlet 1012 and the liquid outlet 1014 can both be connected to the washing tub. In this way, the water flow of the water inlet 1011 can be used as a power source to realize the automatic delivery of the treatment agent in the storage chamber.
