Description

Technical Field

[0001] This application relates to the field of garment steamer technology, and more particularly to a garment steamer. Background Technology

[0002] A garment steamer, also known as a hanging iron or standing iron, is a machine that allows you to steam clothes while they are hanging. It works by continuously contacting the clothes with hot steam generated inside, softening the fabric fibers and smoothing the clothes by pulling and pressing them, leaving them looking brand new. However, garment steamers on the market still have many shortcomings: some are too bulky to carry, some have small water tanks that require manual refilling when the tank is low, making operation cumbersome, and some have complex structures and numerous wiring components.

[0003] Therefore, it is essential to provide a garment steamer that can not only automatically replenish water, but also has a simple and reasonable structure and is flexible and convenient to use. Utility Model Content

[0004] Therefore, it is necessary to provide a garment steamer to address the aforementioned problems.

[0005] This application provides a garment steamer, including a main unit and a base. The base has a receiving portion for placing the main unit and automatically filling it with water. One of the main unit and the base is equipped with a magnet, and the other is equipped with a Hall effect sensor. When the main unit is placed in the receiving portion, the magnet and the Hall effect sensor approach each other and generate an electrical signal for automatic water filling. The main unit receives the electrical signal and starts pumping water to achieve automatic water filling.

[0006] Furthermore, a heating element bracket is provided at the position where the receiving part contacts the main unit of the garment steamer. On the one hand, this facilitates the stable placement of the main unit of the garment steamer, ensuring that the receiving part is in close contact with the base plate of the main unit of the garment steamer, and preventing displacement or loosening. On the other hand, it can reduce heat loss when the receiving part contacts the main unit of the garment steamer, and also provide heat insulation and safety protection for the base.

[0007] Furthermore, the garment steamer main unit includes a small main water tank and a heating element. The base includes a large water tank for water supply. The small main water tank is connected to the heating element through a main hose assembly, a first pump body, and a main water supply pipe. The large water tank is connected to the small main water tank through a large water tank suction hose assembly, a main suction connector assembly, a second pump body, and a main hose assembly. The capacity of the small main water tank is smaller than that of the large water tank, which reduces the weight of the garment steamer main unit and facilitates its use and operation.

[0008] Furthermore, the garment steamer main unit also includes a temperature controller, which is electrically connected to the heating element and is used to control the temperature of the heating element under different working conditions of the garment steamer main unit. This intelligently adjusts the working temperature of the heating element, saves ironing time, and makes ironing clothes more efficient.

[0009] Furthermore, the main water tank is equipped with a cover that allows for manual water filling. In addition to placing the garment steamer main unit in the container for water filling, it also provides a manual water filling method, making it more flexible to use.

[0010] Furthermore, the garment steamer main unit also includes: a main unit controller, which is electrically connected to the power cord, the first pump body, and the second pump body. The main unit controller receives the electrical signal generated by the magnet approaching the Hall sensor, which indicates automatic water injection. It controls the first pump body to stop supplying water to the heating element and controls the second pump body to start pumping water, thereby automatically filling the small water tank of the main unit with water. When the garment steamer main unit is lifted away from the housing, the magnet separates from the Hall sensor, the electrical signal for automatic water injection is automatically disconnected, and the first pump body will automatically stop pumping water without any other operation.

[0011] Furthermore, the garment steamer main unit also includes:

[0012] A liquid level sensor is used to monitor the liquid level of the main small water tank and to send an electrical signal to stop automatic water filling when the liquid level of the main small water tank reaches a threshold.

[0013] The main controller is electrically connected to the power cord and the second pump body. The main controller receives an electrical signal from the liquid level sensor to stop automatic water filling and controls the second pump body to stop supplying water to the main water tank. Therefore, it realizes that you only need to place the main unit of the garment steamer in the container for automatic water filling, without distraction or other operations. The liquid level sensor will monitor the liquid level of the main water tank at all times, and will automatically stop water filling as long as the liquid level threshold is reached. It is convenient to use and there is no need to worry about water overflowing. It realizes the functions of automatic water filling and automatic stopping of water filling after completion.

[0014] Furthermore, the main body water pump connector assembly is located on the main unit of the garment steamer, and the large water tank water pump hose assembly is located on the large water tank. The main body water pump connector assembly and the large water tank water pump hose assembly are detachably connected. When the main unit of the garment steamer is placed in the receiving part, the main body water pump connector assembly is connected to the large water tank water pump hose assembly. When the main unit of the garment steamer is picked up, the main body water pump connector assembly is separated from the large water tank water pump hose assembly, and at least a portion of the large water tank water pump hose assembly is located inside the large water tank.

[0015] Furthermore, the large water tank suction hose assembly is equipped with a water suction filter head at one end near the bottom of the large water tank, ensuring that the steam heated by the heating element of the garment steamer is clean and free of stains, preventing soiling of the fabric and also improving the service life of the garment steamer.

[0016] The beneficial effects of the above technical solution are:

[0017] 1. In the garment steamer main unit and base, one is equipped with a magnet and the other with a Hall effect sensor. When the garment steamer main unit is placed in the housing, the magnet and the Hall effect sensor approach each other and generate an electrical signal for automatic water filling. The garment steamer main unit receives the electrical signal and starts automatic water filling. When in use, simply lift the garment steamer main unit, and the electrical signal for automatic water filling will automatically disconnect. No other operation is required. It is ready to use immediately and highly practical. This utility model has the beneficial effects of automatic water replenishment, simple and reasonable structure, and flexible and convenient use.

[0018] 2. The garment steamer also includes a liquid level sensor to monitor the liquid level in the main water tank. When the liquid level in the main water tank reaches a threshold, it sends an electrical signal to stop automatic water filling. The garment steamer receives the signal and stops filling the water. There is no need to worry about water overflowing. It is easy to use and requires no operation. It realizes the functions of automatic water filling and automatic stopping of water filling after completion. Attached Figure Description

The water in the main body small water tank 10 flows through the main body hose group 14, electromagnetic pump 21, and main body water supply pipe 14, and then enters the heating element 20 to be heated into steam. Finally, it is discharged from the steam chamber of the main unit bottom plate, thereby ironing the clothes.

[0035] Figure 6 This is an exploded view of the base structure of a garment steamer according to one embodiment, combined with... Figure 1 and Figure 6 As can be seen by those skilled in the art, the base 200 includes a large water tank 300 for supplying water to the garment steamer main unit 100 and a base 29 for supporting the garment steamer main unit 100. The base 29 is fitted into the bottom shell 30 of the large water tank. The receiving part 31 for placing the garment steamer main unit 100 for automatic water filling is located on the upper side of the base 29. The upper side of the base 29 is provided with a heating element bracket 28 for supporting the heating element 20 of the garment steamer main unit 100. On the one hand, this facilitates the stable placement of the garment steamer main unit 100 and ensures close contact with the receiving part 31 to avoid displacement or loosening. On the other hand, the heating element bracket 28 is usually made of high-temperature resistant insulating material (such as mica, ceramic or engineering plastic) or has an air layer or heat insulation coating, which can reduce heat loss when the receiving part 31 contacts the garment steamer main unit 100 and also provide heat insulation and safety protection for the base 200.

[0036] A semi-enclosed upper shell 25 is connected to the upper side of the bottom shell 30 of the large water tank. A magnet 27 is provided in the enclosed cavity of the upper shell 25 near the receiving part 31. When the main unit 100 of the garment steamer is placed in the receiving part 31, the magnet 27 approaches the Hall sensor 11 and generates an electrical signal for automatic water injection (the principle of electromagnetic induction is common knowledge to those skilled in the art and will not be elaborated here). The main control PCB board 3 receives the electrical signal and controls the start of the water pump 13. The water pump 13 is the main unit of this embodiment. In one preferred embodiment of the second pump body, automatic water filling is achieved. The upper side of the upper shell 25 of the large water tank is connected to a large water tank cover 23 for sealing. The large water tank cover 23 is provided with a large water tank filling cap 24 for filling the large water tank 300 with water. The interior of the large water tank 300 is provided with a large water tank suction hose assembly 26. The water outlet end of the large water tank suction hose assembly 26 passes through the closed cavity of the upper shell 29 of the large water tank and extends to the outside of the base 300 for connecting to the main body suction connector assembly 15 of the garment steamer main unit 100.

[0037] like Figure 1 As shown, in this embodiment, a water suction filter head 32 is preferably installed at one end of the large water tank suction hose assembly 26 near the bottom of the large water tank to ensure that the steam heated by the heating element 20 of the garment steamer main unit 100 is clean and free of stains, thus avoiding soiling the fabric and improving the service life of the garment steamer main unit.

[0038] like Figure 1 As shown, in this embodiment, a reinforcing rib 33 is preferably provided inside the base 29 to provide better support for the garment steamer main unit 100.

[0039] Figure 7 This is a schematic diagram of the water pumping circuit during the automatic water filling process of the garment steamer in this embodiment. Figure 8 This is a schematic diagram of the water inlet circuit during automatic water filling of the garment steamer in this embodiment. The main body water pump connector assembly 15 is connected to the water pump connector 12, and the water pump connector 12 is connected to the water pump 13. Figure 7 , Figure 8 and Figure 9 The arrows indicate the direction of water flow. When the water in the main small water tank 10 is insufficient, the garment steamer main unit 100 is placed on the receiving part 31 of the base 200. At this time, the magnet 27 approaches the Hall sensor 11 and generates an electrical signal for automatic water injection. The main control PCB board 3 receives the electrical signal and controls the start of the water pump 13. The water inside the large water tank 300 passes through the large water tank water pump hose assembly 26, the main water pump connector assembly 15, the water pump connector 12, the water pump 13, and the main hose assembly 14, and then enters the main small water tank 10 to achieve automatic water injection.

[0040] In a preferred embodiment, an infrared sensing element 8 is installed on the outside of the opening of the main water tank 10. When the liquid level in the main water tank 10 reaches a threshold, the infrared sensing element 8 sends an electrical signal to the main control PCB board 3 to stop automatic water filling. The main control PCB board 3 controls the water pump 13 to stop pumping water, and the water filling is completed automatically, preventing water from overflowing from the main water tank 10. In addition, when emergency use is required, even if the main water tank 10 is not full, as long as the garment steamer main unit 100 is picked up and separated from the base 200, the Hall element 11 and the magnet 27 will automatically disconnect, there will be no electrical signal output, and the water pump 13 will automatically stop working. No manual or electric operation is required, and it can be used immediately.

[0041] Figure 9 This is a schematic diagram of the connection between the large water tank suction hose assembly 26 and the main body suction connector assembly 15 of the garment steamer in an embodiment. The arrows in the figure indicate the water supply route. As shown in the figure, the large water tank suction hose assembly 26 includes a large water tank external connector 261 and a first one-way valve 262. The one-way valve here should be interpreted broadly by those skilled in the art. It can be replaced by a component similar to a one-way valve, consisting of silicone, beads, springs and bends, to prevent water from flowing back into the large water tank 300 from the small water tank 28 of the main body.

[0042] In this embodiment, the main body water pumping connector group 15 is preferably configured with a structure similar to the large water tank water pumping hose group 26, including a small water tank external connector 151 and a second one-way valve 152. The small water tank external connector 151 and the large water tank external connector 261 are arranged opposite to each other and are detachably connected. The second one-way valve 152 and the first one-way valve 262 are arranged in opposite directions. The second one-way valve 152 is also used to prevent water from flowing back into the large water tank 300 from the main body small water tank 10, and to block the main body small water tank 10 when the garment steamer main unit 100 is working to prevent water from flowing out.

[0043] How this embodiment works:

[0044] First, open the small water tank cap 9 and fill it with water. Then, plug in the power cord 22 to turn on the power and press the switch button 8. The machine will then be powered on and the heating element 20 will heat up. At the same time, the electromagnetic pump 21 will start. The electromagnetic pump 21 will draw water from the main body small water tank 10 and deliver it to the heating element 20 through the main body water delivery hose 16. During the process of delivering water to the heating element 20, due to the limited area of ​​the heating element 20 and the small steam outlet, and under the action of the electromagnetic pump 21, the bottom plate of the garment steamer will generate pressure. The steam in the heating element 20 will be sprayed directly out of the steam chamber under pressure to iron clothes until the water in the main body small water tank 10 is used up.

[0045] Next, place the garment steamer main unit back into the housing 31 of the base 29. The large water tank 300 is already full of water through the large water tank filling cap 24. The main body water pump connector assembly 15 is connected to the large water tank water pump hose assembly 26. At this time, the Hall sensor 11 and the magnet 27 approach each other and generate an electrical signal for automatic water injection. The main control PCB board 3 receives the electrical signal and controls the water pump 13 to work and automatically pump water, delivering the water in the large water tank 300 to the main body small water tank 10. When the main body small water tank 10 is full, the infrared sensor 8 detects the liquid level and outputs an electrical signal to stop automatic water injection to the main control PCB board 3. After the water is full, the water pump 13 automatically stops working. During the water pumping process, the heating element 20 maintains a certain suitable temperature under the control of the temperature control switch, i.e., the temperature controller 19. When working, it is adjusted to the working temperature. This cycle continues until the water in the large water tank 300 is used up or the clothes are finished being ironed.

[0046] During this process, as long as the garment steamer main unit 100 is lifted from the receiving part 31, that is, the Hall sensor 11 is separated from the magnet 27, the water pump 13 will automatically stop. It is easy to operate and has a high degree of automation. The garment steamer structure provided in this embodiment has the beneficial effects of automatic water replenishment, simple and reasonable structure, and flexible and convenient use.

[0047] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
