Steady flow water supply device and steam appliance

Abstract

The application discloses a steady-flow water supply device and a steam appliance, and belongs to the field of ironing devices. The existing steam appliance water conveying pipeline pressure is unstable, which easily causes water conveying pipeline leakage, unstable steam temperature and steam quantity, and influences ironing. The water pressure stabilizer is arranged for the water supply device. When the water pressure at the position of the water pressure stabilizer is relatively large, water flows into the water pressure stabilizer to reduce the water pressure. When the water pressure at the position of the water pressure stabilizer changes from large to small, the water pressure stabilizer outputs water to supplement the water pressure. Thus, the pressure position of the water conveying pipeline is relatively stable, stable water conveying and stable steam generation are realized, and the water conveying pipeline leakage caused by unstable pressure is avoided.

[0002] Steam appliances, such as the handheld steam brush disclosed in patent application publication number CN104831510A, are steam-generating devices that generate steam for ironing, cleaning, and high-temperature disinfection. These products operate by pumping water from a water tank through an electromagnetic pump to a steam generator, where it is heated and vaporized, producing continuous high-temperature steam.

[0003] When Figure 1 When hanging ironing as shown, steam can be released freely and the pressure in the steam generator is stable; Figure 2 As shown in the figure, when performing flat ironing, the steam outlet contacts the clothes and is blocked, steam release is hindered, the pressure in the steam generator increases and is fed back to the water supply pipeline. In order to continue working, the water pump does not stop or reduce the water supply, which causes the pressure in the water supply pipeline to increase, which is prone to defects such as leakage.

[0004] Some water tanks that use energy storage elastic parts to store energy can automatically transfer water outward with the help of the elastic force of the energy storage elastic parts. However, in the process of transferring water outward, the pressure changes from large to small, and the water flow is unstable, resulting in unstable steam temperature and steam volume, which affects ironing.

[0048] The present invention will be further described below with reference to the accompanying drawings.

[0049] Example 1

[0050] like Figure 1-2 The steam brush 100a is a steam appliance. It includes a housing 101a, a steam generator 200a, a water pump 600, a water pressure stabilizer 500b, and a water tank 300. During operation, the water pump transfers water from the water tank to the steam generator, which heats the water, converts it into steam, and sprays it out for ironing, disinfecting, or cleaning. The water pressure stabilizer is connected to the water supply line between the water pump and the steam generator and communicates with the water supply line. The water tank, water supply line, and water pressure stabilizer form a steady-flow water supply device.

[0051] The water pressure stabilizer 500b is as follows Figure 7As shown, it includes a container 501b, a pressure-stabilizing plug 502b, and a pressure-stabilizing spring 503b. The container has a pressure-stabilizing chamber 504b. The water pressure stabilizer is connected to the water supply pipeline 400 via two interfaces 505a and 505b, connecting the pressure-stabilizing chamber to the water supply pipeline. The pressure-stabilizing plug 502b is slidably assembled on the container 501b, and the sliding of the pressure-stabilizing plug causes the volume of the pressure-stabilizing chamber to change. The pressure-stabilizing spring 305b acts on the pressure-stabilizing plug 502b. The elastic force exerted by the pressure-stabilizing spring on the pressure-stabilizing plug is in the opposite direction to the pressure exerted by the water flow in the water supply device on the pressure-stabilizing plug. The pressure-stabilizing spring is a helical compression spring that supports the pressure-stabilizing plug and applies a thrust to the pressure-stabilizing plug. In a specific implementation, it can be a helical compression spring that pulls the pressure-stabilizing plug, and the pressure-stabilizing spring exerts a tensile force on the pressure-stabilizing plug.

[0052] Given this structure, the steam brush Figure 1 When hanging ironing, steam can be released freely, the pressure in the steam generator is stable, the pressure in the water pipeline is stable, and the water pump continuously delivers water. Figure 2 When performing flat ironing, the steam outlet contacts the clothes, steam release is blocked, the pressure in the steam generator increases and is fed back to the water pipeline. In order to continue working, the water pump does not stop or reduce water delivery, which causes the pressure in the water pipeline to increase, forcing water to flow into the pressure stabilizing chamber 504b to reduce the pressure in the water pipeline and avoid leakage caused by the pressure increase. Figure 2 Flat ironing shown converted to Figure 1 When hanging clothes for steaming, steam can be released freely, the pressure of the water pipeline will decrease, and the pressure stabilizing chamber 504b will output water to supplement the water pressure, thereby ensuring the water flow to the steam generator.

[0053] During specific implementation, the water pressure stabilizer may be an elastic container.

[0054] Example 2

[0055] like Figure 3-4 The steam brush shown here also serves as a steam appliance. The steam brush 100b comprises a housing 101b, a steam generator 200b, a water pressure stabilizer 500a, and an energy storage tank 700. During operation, the energy storage tank 700 automatically supplies water to the steam generator 200b, which heats the water, converts it into steam, and sprays it out for ironing, disinfecting, or cleaning. The water pressure stabilizer 500a is connected to the water supply plug 702 of the energy storage tank 700, which communicates with the water storage chamber. The energy storage tank, water supply pipeline, and water pressure stabilizer together form a steady-flow water supply device. In practice, the energy storage tank 700 can also be connected to other locations within the water storage chamber.

[0056] The energy storage water tank 700 comprises a housing 701, a water transfer plug 702, and an energy storage elastic member 703. The water transfer plug 702 is slidably mounted on the housing 701 and forms a water storage chamber 704 with the housing. The sliding of the water transfer plug 702 causes the volume of the water storage chamber 704 to change. The energy storage elastic member 703 acts on the water transfer plug 702 to force it to slide, transferring the water stored in the water storage chamber outward. The energy storage elastic member applies a pulling force to the water transfer plug, and in practice, can also apply a pushing force.

[0057] The water pressure stabilizer 500a is as follows Figure 6 As shown, it includes a container 501a, a pressure-stabilizing plug 502a, and a pressure-stabilizing spring 503a. The container has a pressure-stabilizing chamber 504a, which is open to the water storage chamber 704. The pressure-stabilizing plug is slidably mounted on the container, and the sliding of the pressure-stabilizing plug causes the volume of the pressure-stabilizing chamber to change. The pressure-stabilizing spring acts on the pressure-stabilizing plug, and the elastic force exerted by the pressure-stabilizing spring on the pressure-stabilizing plug is opposite to the pressure of the water flow in the water supply device on the pressure-stabilizing plug. The pressure-stabilizing spring is a helical compression spring that supports the pressure-stabilizing plug and applies a thrust to the pressure-stabilizing plug. In a specific implementation, it can be a helical compression spring that pulls the pressure-stabilizing plug, and the pressure-stabilizing spring exerts a tensile force on the pressure-stabilizing plug.

[0058] Given this structure, the steam brush Figure 3 When the volume of the water storage chamber 704 is small, the elastic force of the water delivery spring is small, the pressure in the water storage chamber is small, and the energy storage water tank can deliver water outward at this pressure. Figure 4 When the volume of water storage chamber 704 is large, the spring force of the water transfer spring is greater, and the pressure within the water storage chamber is higher. The water in the water storage chamber pushes the pressure-stabilizing plunger to expand the volume of pressure-stabilizing chamber 504a, reducing the pressure in water storage chamber 704 and stabilizing the pressure there. As the water in the water storage chamber decreases, the volume decreases, the spring force of the water transfer spring decreases, and the pressure-stabilizing chamber 504a transfers water to the water storage chamber 704 to replenish the water pressure, ensuring the water flow to the steam generator.

[0059] During specific implementation, the water pressure stabilizer may be an elastic container.

[0060] Example 3

[0061] like Figure 5-6 The steam brush shown here also serves as a steam appliance. This steam brush 100c comprises a housing, a steam generator 200b, a water pressure stabilizer 500b, and a water storage tank 700. During operation, the water storage tank automatically supplies water to the steam generator, which heats the water, converts it into steam, and sprays it out for ironing, disinfecting, or cleaning. The water pressure stabilizer is connected to the water supply line 400 between the water storage tank and the steam generator. The water storage tank, water supply line, and water pressure stabilizer together form a steady-flow water supply device.

[0062] The energy storage tanks Figure 3-4 As shown, the system comprises a housing, a water transfer slide, and an energy storage spring. The water transfer slide is slidably mounted on the housing and forms a water storage chamber with the housing. The sliding of the water transfer slide causes the volume of the water storage chamber to change. The energy storage spring acts on the water transfer slide to force the slide to slide, transferring the water in the water storage chamber outward. The energy storage spring exerts a pulling force on the water transfer slide, and in practice, may also exert a pushing force.

[0063] The water pressure stabilizer is as follows Figure 7 As shown, in view of the above description, it will not be repeated here.

[0064] In view of this structure, when the volume of the water storage chamber 704 is small, the elastic force of the energy storage elastic member 703 is small, and the pressure in the water storage chamber 704 is small. The water storage chamber 704 can output water outward at this pressure. Figure 6 When the water storage chamber is large, the spring force of the energy storage spring 703 is greater, the pressure within the water storage chamber 704 is higher, and the pressure in the water supply pipeline also increases, forcing water to flow into the pressure-stabilizing chamber 500b, reducing the pressure in the water supply pipeline and preventing leaks caused by increased pressure. As the water storage chamber decreases, the volume of the water storage chamber decreases, the spring force of the water supply spring decreases, and the water pressure in the water storage chamber decreases. The pressure-stabilizing chamber then pumps water outward to replenish the water pressure, ensuring the water flow to the steam generator.

[0065] During specific implementation, the water pressure stabilizer may be an elastic container.

[0066] In the above embodiment, the water flow rate of the device with water pressure stabilizer and the device without water pressure stabilizer is as follows: Figure 8 As shown, curve A is the water flow curve when the water pressure stabilizer is configured, and curve A is the water flow curve when the water pressure stabilizer is not configured. As shown in the figure, the water flow when the water pressure stabilizer is configured is more stable.
