Description

Technical Field

[0001] The present invention belongs to ironing devices, and particularly relates to an automatic water replenishing device and a clothes ironing appliance. Background Art

[0002] The water tank of a traditional handheld steam brush generally has a small capacity. When the capacity is large, it is easy for the operator to get tired when holding it in the air for ironing, and it is necessary to frequently add water to the water tank during use, which is a troublesome thing.

[0003] The invention patent application with the publication number of CN 110608428 A discloses a separable and quickly water replenishing steam generating device, which separates the steam jet head from the base. A cable is provided on the steam jet head, and a water tank is provided on the base, reducing the weight of the steam jet head. During use, the steam jet head can be casually placed on the base to fill water, improving the convenience of use. Moreover, since the cable is provided on the steam jet head, connecting the cable to a socket can make the steam jet head continuously work. This solution depends on the operation of a water pump for water replenishment, and the configuration of the water pump makes the product costly and the structure complex.

[0004] The invention patent application with the publication number of CN109695144A discloses an ironing machine with self-water supply. The ironing machine includes a base and an ironing body. A steam generator and a body water tank are provided in the ironing body. A variable water tank is provided on the base. The variable water tank includes a movable part and a fixed part. The movable part and the fixed part enclose a sealed cavity capable of holding water. The movable part can move relative to the fixed part to make the volume of the cavity shrink or expand. When the movable part moves under an external force to make the volume of the cavity shrink, a compression effect is generated on the water in the cavity. At the same time, cooperating with the opening of the first switch and the second switch, water can flow out from the water outlet and be injected into the body water tank through the water injection port. Since the variable water tank is formed by enclosing a sealed cavity capable of holding water by the movable part and the fixed part, it is like a hydraulic cylinder. The fixed part is equivalent to the cylinder body of the hydraulic cylinder, and the movable part is equivalent to the piston of the hydraulic cylinder. Its structure is complex. Especially when the movable part and the fixed part enclose to form a sealed cavity, it is necessary to establish a seal between the two. Generally, a sealing ring is sleeved on the movable part and the sealing ring is pressed against the inner wall of the fixed part, which results in a large frictional force when the movable part moves relative to the fixed part. Moreover, when the ironing body is placed on the base, only a small part of the weight of the ironing body can be applied to the movable part. Therefore, when the ironing body is placed on the base and the variable water tank replenishes water to the body water tank, the movable part needs to move relative to the fixed part under an external force (such as the user continuously pressing the handle of the ironing body during the water replenishment process), and the operation is troublesome.

[0018] As a preferred technical means for the automatic water replenishment device: a first elastomer is configured for the small water tank, and the elastic force of the first elastomer squeezes the small water tank to reduce the volume of the small water tank so as to transport water out from the water outlet; when the small water tank absorbs the water stored in the large water tank, the elastic force of the first elastomer is overcome.

[0019] As a preferred technical means for the automatic water replenishment device: a recess for placing the small water tank is arranged on the large water tank.

[0020] As a preferred technical means for the automatic water replenishment device: the small water tank is provided with a water inlet which can be separated from the large water tank and can be independently filled with water, and the water inlet is provided with a plug.

[0044] The present invention will be further described below in conjunction with the accompanying drawings of the specification.

[0045] As Figure 1 shown, a clothes ironing appliance is used to generate steam for ironing clothes. The clothes ironing appliance includes a gripable main body 100, and a steam generating device 200 and a control valve 300 are provided inside the main body 100. The steam generating device is used to heat the supplied water and convert it into steam for output. Supplying water to the steam generating device is completed by a water supply device. This water supply device is not a water pump, but a structure that relies on its own stored energy to supply water outward. This water supply device does not use electricity during operation, and has low manufacturing and usage costs. The control valve is connected to the pipeline between the water supply device and the steam generating device and is used to control whether to supply water to the steam generating device. The control valve is assembled at a gripable position on the main body for operation. When steam needs to be generated, the control valve is opened; when steam does not need to be generated, the control valve is closed.

[0046] The water supply device, as Figures 2 - 5 shown, is composed of a soft or telescopic and deformable small water tank 400 and a first elastic body 500. The small water tank 400 has a water outlet 401, and the elastic force of the first elastic body squeezes the small water tank to reduce the volume of the small water tank so as to supply water outward from the water outlet. In order to restrict the small water tank and effectively squeeze the small water tank, the small water tank is arranged inside the outer shell 402.

[0047] Figures 2 - 5The small water tank 400 shown is composed of a first end plate 403, a second end plate 404, and a telescopic tube 405 connected between the first end plate and the second end plate. The elastic force of the first elastic body 500 is applied to the first end plate 403 to urge the first end plate to move, causing the telescopic tube to shorten and reducing the volume of the small water tank. The water outlet 401 is provided on the first end plate 403. Moreover, a guide rod 406 is arranged on the first end plate. The guide rod 406 extends through the inner cavity of the small water tank to the second end plate and is in sealing telescopic fit with the second end plate. When the first end plate moves to make the telescopic tube shorten and reduce the volume of the small water tank, the guide rod has the function of guiding the first end plate to prevent the first end plate from tilting.

[0048] For the sake of simple structure, a through hole 407 communicating the water outlet with the inner cavity of the small water tank is provided on the guide rod 406. Therefore, it is preferable that the guide rod is tubular, with the lower end closed, and the through hole is provided on the side wall of its upper end to ensure that the through hole is located in the inner cavity of the small water tank when the volume of the small water tank changes.

[0049] For the convenience of replenishing water to the small water tank, it is preferable that the small water tank 400 is detachably connected to the main body 100; when working, the small water tank is connected to the main body, and when replenishing water to the small water tank, the small water tank is detached from the main body. As Figure 5 shown, by inverting the small water tank, water can be replenished into the small water tank through the water filling port 408 provided on the small water tank. After filling with water, the water filling port is blocked with a plug 409. Obviously, when the small water tank is fixedly connected to the main body and cannot be detached, the small water tank can also be replenished with water through the water filling port by inverting the main body with the small water tank. In the figure, the water supply device is arranged at the rear end 105 of the bottom or top of the main body, which does not affect the configuration and layout of other structures, so there is a larger design space.

[0050] The so-called detachable connection is that an inner ring edge 101 is provided at the lower end of the main body, a notch is provided on the inner ring edge, and a hook 410 corresponding to the notch is provided at the upper end of the outer shell 402 as a quick connection structure. Then, by making the hook cross the notch and rotating the outer shell, the hook can be hooked on the inner ring edge for connection, and for detachment, the reverse operation can be performed. Equivalently, the outer shell can also be connected to the lower part of the main body through a threaded connection.

[0051] When the small water tank is detachable, the water outlet 401 is provided with a first water valve, which has a first valve port 411 and a first valve plug 412, and the first valve plug is supported by a first spring 413, and the first spring applies an elastic force to the first valve port to the first valve plug. A moving part 102 is provided on the main body, and a water delivery pipe 103 is provided on the moving part. When the small water tank is connected to the main body, the first valve plug 412 is pushed away from the first valve port 411 by the water delivery pipe 103, and the first water valve is opened. The water delivery pipe 103 is inserted into the water outlet 401 to achieve docking with the water outlet and connect the water outlet to the water delivery pipeline. The small water tank can deliver water to the outside through the water outlet and the water delivery pipe. When the small water tank is detached from the main body, the water delivery pipe is disengaged from the water outlet, and the water outlet is moved out of the water delivery pipeline. The first valve plug blocks the first valve port by the elastic force of the first spring and closes the first water valve, and the water outlet is closed.

[0052] The moving part 102 is arranged at the lower end of the main body 100, and is limited by the inner ring edge 101 at the lower end of the main body through the step 104 so as not to be able to escape from the main body. The first elastic body 500 acts on the moving part 102 and applies elastic force to the small water tank through the moving part to squeeze the small water tank. There is no need to seal between the moving part and the main body, and the two can move flexibly relative to each other with little resistance. When the small water tank conveys water outward, the moving part uses the elastic force of the first elastic body to make the water conveying pipe and the water outlet that are docked together move synchronously, so as to keep the water conveying pipe and the water outlet docked and connected.

[0053] In the case of reducing the volume of the small water tank by squeezing and then transferring water outward, the small water tank disposed in the outer shell may be a flexible water bag.

[0054] The control valve 300 includes an inlet 301, an outlet 302 and a second valve port 303 arranged between the inlet and the outlet. The second valve port is provided with a second valve plug 304. The second valve plug seals the second valve port with the aid of the elastic force of a second spring 305. The second valve plug is connected to a valve opening mechanism. The valve opening mechanism includes a control member 306 and a lever 307 arranged on the surface of the main body. The second spring acts on the lever to indirectly apply elastic force to the second valve plug.

[0055] like Figure 6 When the control member is not operated, the elastic force of the second spring 305 acts on the lower end of the lever, causing the upper end of the lever to move rightward with the second valve plug to block the second valve port, so that the inlet and the outlet are disconnected and the control valve is closed. Figure 7 When the control member is pressed to the right as shown, the pressing force acts on the lower end of the lever, and the elastic force of the second spring is overcome, causing the upper end of the lever to move to the left with the second valve plug leaving the second valve port, connecting the inlet and the outlet, and opening the control valve.

[0056] Therefore, the water outlet pipe is connected to the inlet of the control valve through a hose 700, and the outlet of the control valve is connected to the steam generating device through a hose. By pressing the control member, the control valve can be opened, enabling the small water tank to supply water to the steam generating device through the control valve to generate steam. When the control member is released, the control valve can be closed, blocking the water outlet path of the small water tank and stopping the small water tank from supplying water to the steam generating device.

[0057] Since the capacity of the small water tank is small, it is necessary to replenish water to the small water tank during operation. Therefore, this clothing ironing appliance further includes Figures 8 - 9 The large water tank 600 shown is used to replenish water to the small water tank in a timely manner. For this purpose, the small water tank 400 is provided with a water replenishing port 414; the large water tank 600 is provided with a water replenishing interface 601; when the water replenishing port is docked with the water replenishing interface, the small water tank sucks the stored water in the large water tank by relying on the negative pressure generated by the increase in its volume to achieve water replenishment.

[0058] As shown in the figure, for the small water tank, when the first end plate moves closer to the second end plate, the telescopic tube shortens to reduce the volume of the small water tank, and when the first end plate moves away from the second end plate, the telescopic tube elongates to increase the volume of the small water tank. The water replenishing port is provided on the second end plate so that the small water tank can be placed on the large water tank together with the main body and the water replenishing port can be docked with the water replenishing interface.

[0059] Moreover, a guide rod is arranged on the first end plate. The guide rod extends through the inner cavity of the small water tank to the second end plate and penetrates through the second end plate. The guide rod is in sealing telescopic fit with the second end plate, and the first end plate is moved away from the second end plate by applying force through the guide rod. A push rod 602 is arranged on the large water tank. When the water replenishing port is docked with the water replenishing interface, the push rod 602 supports the guide rod 406. Then, during the water replenishing process, the first end plate remains stationary relative to the large water tank, while the main body, the outer shell, and the second end plate slowly descend. Thus, it is equivalent to the first end plate moving away from the second end plate to make the telescopic tube elongate to increase the volume of the small water tank, and accordingly, a negative pressure is generated to suck the stored water in the large water tank to achieve water replenishment.

[0060] To prevent the stored water in the small water tank from flowing out of the water replenishing port during water replenishment, a third water valve 415 is arranged at the water replenishing port 414. When the water replenishing port is docked with the water replenishing interface, the third water valve is opened to connect the water replenishing port and the water replenishing interface, and when the water replenishing port is disconnected from the water replenishing interface, the third water valve is closed. Specifically, the third water valve 415 has a third valve port 416, a third valve plug 417 is arranged for the third valve port, the third valve plug is located in the third valve cavity 418. When the water replenishing port is disconnected from the water replenishing interface, the third valve plug blocks the third valve port by the elastic force of the third spring 419 to close the third water valve, and when the water replenishing port is docked with the water replenishing interface, the third valve plug is pushed away from the third valve port by the water replenishing interface to open the third water valve.

[0061] Further, the third water valve has a third connection pipe 420. A flow gap 421 is provided at the port of the third connection pipe. The third valve plug has a third valve stem 422, and the third valve stem extends outside the third connection pipe. The water replenishing interface is made into a water valve structure, which is herein referred to as the fourth water valve. The fourth water valve has a fourth valve cavity 603, a fourth valve plug 604, a fourth valve port 605, and a fourth spring 606. When the water replenishing port is disengaged from the water replenishing interface, the fourth valve plug blocks the water replenishing interface by the elastic force of the fourth spring. When the water replenishing port is docked with the water replenishing interface, the third connection pipe is inserted into the water replenishing interface and pushes the fourth valve plug away from the water replenishing interface to open the water replenishing interface. The fourth valve plug pushes against the third valve stem and pushes the third valve plug away from the third valve port. Accordingly, when replenishing water, as Figure 11 shown, the small water tank sucks the stored water in the large water tank into the small water tank through the connected third valve cavity, third valve port, third connection pipe, flow gap, fourth valve cavity, and the hose connecting the fourth valve cavity and the inner cavity of the large water tank. In the states as Figures 1 - 3 , Figure 5 , Figure 8 shown, both the water replenishing port and the water replenishing interface are closed.

[0062] In order to continuously increase the volume of the small water tank to generate negative pressure during water replenishment, the water replenishing interface is arranged on a lifting frame 607, and the lifting frame is upwardly supported by a second elastic body 608. The small water tank is placed on the lifting frame so that the water replenishing port is docked with the water replenishing interface. When the small water tank sucks the stored water in the large water tank, the elastic force of the second elastic body is overcome and the lifting frame descends, and the outer shell and the second end plate descend accordingly. As Figures 10 - 11 shown, when the small water tank and the main body are placed in the large water tank together, the gravity of the small water tank, the outer shell, and the main body is applied to the lifting frame, thereby promoting the volume of the small water tank to increase and generate negative pressure, and the elastic force of the first elastic body is overcome. Therefore, the weight of the main body is beneficial to the generation of negative pressure in the small water tank. When it is desired to accelerate the water absorption of the small water tank, the main body can be manually pressed downward to increase the negative pressure in the small water tank, so that the small water tank has a greater suction force to suck water from the large water tank.

[0063] In order to facilitate the small water tank to be stably and reliably placed on the large water tank, a recess 609 for placing the water tank is configured on the large water tank.

[0064] As shown in the figure, the small water tank is configured at the bottom of the main body. The large water tank is configured as a base for the main body with the small water tank to be placed on the large water tank as Figure 10 shown for water replenishment. In this way, during the use interval, the user only needs to place the main body with the small water tank in the recess of the large water tank. The large water tank bears the main body and the small water tank like a base.

[0065] In order to add water to the large water tank, a water filling port is provided on the large water tank and a lid is configured for the water filling port.

[0066] The first elastic body and the second elastic body mentioned above are preferably spiral compression springs as shown in the figure.
