Description

Technical Field

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

[0002] Garment steamers contain an evaporator for generating steam. These evaporators include those for 110V and those for 220V power, resulting in garment steamers being categorized as either 110V or 220V compatible. Connecting a garment steamer compatible with 110V to a 220V power supply could cause a fire, posing a significant danger to the user. Conversely, when a garment steamer compatible with 220V is connected to a 110V power supply, it cannot perform its ironing function. In summary, existing garment steamers have poor compatibility. Summary of the Invention

[0003] In view of the above-mentioned defects in the prior art, the present invention provides a garment steamer, which aims to solve the problem of poor adaptability of existing garment steamers.

[0004] To solve the above-mentioned technical problems, the present invention provides a garment steamer, comprising:

[0005] Water tanks are used for storing water;

[0006] An evaporation assembly, connected to the water tank and used to generate steam, includes a first heating element and a second heating element. The resistance of the first heating element is adapted to a 110V power supply, and the resistance of the second heating element is adapted to a 220V power supply.

[0007] The switching component automatically connects a 110V power supply to the first heating element or automatically connects a 220V power supply to the second heating element.

[0008] Furthermore, the switching component includes a relay, the relay comprising:

[0009] The first switch is connected to the first heating element by default.

[0010] When the garment steamer is connected to a 110V power supply, the first switch remains connected to the first heating element; and

[0011] When the garment steamer is connected to a 220V power supply, the relay generates a first magnetic force that can move the first switch, connecting the first switch to the second heating element.

[0012] Furthermore, the garment steamer also includes:

[0013] Microcontroller; and

[0014] The first water pump is electrically connected to the microcontroller, and the microcontroller controls the pumping speed of the first water pump to adjust the steam output of the garment steamer.

[0015] Furthermore, the garment steamer also includes:

[0016] The first water pump has a power of 1-10W; and

[0017] The step-down module reduces the input voltage to a level suitable for the operation of the first water pump when the garment steamer is connected to a 220V power supply.

[0018] Furthermore, the garment steamer also includes:

[0019] A first temperature controller is used to detect the first temperature of the evaporation component. When the first temperature exceeds the first preset temperature, the first temperature controller disconnects the evaporation component from the power supply.

[0020] Furthermore, the garment steamer also includes:

[0021] First water pump; and

[0022] The second temperature controller is used to detect the second temperature of the evaporation component. When the second temperature reaches the second preset temperature, the second temperature controller controls the first water pump to deliver water from the water tank to the evaporation component.

[0023] Furthermore, the switching component includes a detector and a silicon controlled rectifier electrically connected to the detector. The detector detects the voltage of the power supply, and the silicon controlled rectifier connects the 110V power supply to the first heating element or the 220V power supply to the second heating element according to the detection result.

[0024] Furthermore, the garment steamer also includes:

[0025] First water pump; and

[0026] The second water pump has a higher power than the first water pump. The switching component automatically connects a 110V power supply to the first heating element and the first pump, or automatically connects a 220V power supply to the second heating element and the second water pump.

[0027] Furthermore, the switching component includes a relay, the relay comprising:

[0028] The first switch is connected to the first heating element by default.

[0029] When the garment steamer is connected to a 110V power supply, the first switch remains connected to the first heating element and the first water pump; and

[0030] When the garment steamer is connected to a 220V power supply, the relay generates a first magnetic force that can move the first switch, connecting the first switch to the second heating element and the second water pump.

[0031] Furthermore, the switching component includes a detector and a silicon controlled rectifier electrically connected to the detector. The detector detects the voltage of the power supply, and the silicon controlled rectifier connects a 110V power supply to the first heating element and the first water pump, or connects a 220V power supply to the second heating element and the second water pump, based on the detection result.

[0032] In this invention, the garment steamer includes a water tank, an evaporation component connected to the water tank and generating steam, and a switching component. The power supply can be an AC voltage of 110-220V. The resistance of the first heating element of the evaporation component is adapted to a 110V power supply, and the resistance of the second heating element is adapted to a 220V power supply. The switching component automatically connects the 110V power supply to the first heating element or automatically connects the 220V power supply to the second heating element. Thus, regardless of whether the garment steamer is connected to a 110V or 220V power supply, it can operate stably without additional user intervention. Attached Figure Description

[0054] refer to Figure 1-13 The first embodiment of the present invention provides a garment steamer 100, which can be a handheld garment steamer.

[0055] The garment steamer 100 includes a housing 10, a water tank 14, an evaporation assembly 20 connected to the water tank 14 and generating steam, and a relay 30 connecting the evaporation assembly 20 to a power supply. The power supply can be an AC voltage of 110-220V. The evaporation assembly 20 includes a first heating element 21 and a second heating element 22. The resistance of the first heating element 21 is adapted to a 110V power supply, and the resistance of the second heating element 22 is adapted to a 220V power supply. The relay 30 automatically connects the 110V power supply to the first heating element 21 or automatically connects the 220V power supply to the second heating element 22. Thus, regardless of whether the garment steamer 100 is connected to a 110V or 220V power supply, the garment steamer can operate stably without additional user intervention.

[0056] The relay 30 includes a first switch 31, which can be a normally closed switch and is connected to the first heating element 21 by default. When the garment steamer 100 is connected to a 110V power supply, the first switch 31 remains connected to the first heating element 21; when the garment steamer 100 is connected to a 220V power supply, the relay 30 generates a first magnetic force that can move the first switch 31, connecting the first switch 31 to the second heating element 22. In one embodiment, relay 30 is an AC 220V relay. When the garment steamer 100 is connected to a power source with a voltage less than 176V, the magnetic force generated by relay 30 is too small to move it to connect with the second heating element 22, and the first switch 31 remains connected to the first heating element 21. When the garment steamer 100 is connected to a power source with a voltage not lower than 176V, the magnetic force generated by relay 30 can move the first switch 31 within approximately 20ms, so that the first switch 31 connects to the second heating element 22. The first switch 31 moves and disconnects from the first heating element 21 in such a short time, so that the power source with a voltage not lower than 176V will not damage the first heating element 21.

[0057] Both the first heating element 21 and the second heating element 22 are made of metal, such as aluminum, aluminum alloy, copper, copper alloy, or magnesium oxide. The first heating element 21 and the second heating element 22 are two independent components, and both can be die-cast into the evaporation chamber 24. The first heating element 21 can be a heating coil, and the second heating element 22 can also be a heating coil. The first heating element 21 can be arranged around the second heating element 22. Alternatively, the first heating element 21 can be spaced apart from the second heating element 22.

[0058] The evaporation assembly 20 also includes an evaporation chamber 24 communicating with the water tank 14, a first cover 23 covering a first side of the evaporation chamber 24, a first receiving member 241 disposed in the evaporation chamber 24 and housing a first heating element 21, a second receiving member 242 disposed in the evaporation chamber 24 and housing a second heating element 22, a second cover 25 covering a second side of the evaporation chamber 24, and a rear cover 27 connected to the evaporation chamber 24. The first heating element 21 and the second heating element 22 can be die-cast into the evaporation chamber 24 and sealed in the first receiving member 241 and the second receiving member 242, respectively.

[0059] The first heating element 21 and the second heating element 22 are housed in the evaporation chamber 24 to heat the water inside the evaporation chamber 24. The evaporation chamber 24, the first receiving member 241, the second receiving member 242, and the first cover 23 together form a first sub-evaporation chamber 2401. The evaporation chamber 24, the first receiving member 241, the second receiving member 242, and the second cover 25 together form a second sub-evaporation chamber 2402 that communicates with the first sub-evaporation chamber 2401.

[0060] The first cover 23 includes an inlet 231 communicating with the water tank 14 and a first through hole 232, which connects the inlet 231 and the first sub-evaporation chamber 2401. The second cover 25 is provided with multiple second through holes 251 and multiple third through holes 252 communicating with the second sub-evaporation chamber 2402. Steam generated in the evaporation chamber 24 flows out through the third through holes 252. The multiple third through holes 252 are arranged in a straight line, and the second through holes 251 are arranged around the third through holes 252 or on both sides of the third through holes 252.

[0061] The evaporation chamber 24 includes a side wall 2403 and a middle wall 2404. The middle wall 2403 has at least one third through hole 2405, which connects the first sub-evaporation chamber 2401 and the second sub-evaporation chamber 2402. The third through hole 2405 may be located in the middle portion of the middle wall 2404. The side wall 2403, the middle wall 2404, the first receiving member 241, the second receiving member 242, and the first cover 23 together form the first sub-evaporation chamber 2401. The side wall 2403, the middle wall 2404, the first receiving member 241, the second receiving member 242, and the second cover 25 together form the second sub-evaporation chamber 2402. In one embodiment, the first receiving member 241 and the second receiving member 242 protrude from both sides of the middle wall 2404, respectively.

[0062] The first sub-evaporation chamber 2401 is provided with a plurality of first guide parts 243, which together form at least one first water flow channel. The second sub-evaporation chamber 2402 is provided with a plurality of second guide parts 246, which together form at least one second water flow channel. In one embodiment, the first water flow channels are arranged symmetrically, and the second water flow channels can also be arranged symmetrically.

[0063] The sidewall 2403 has a protruding first connecting plate 244 and a second connecting plate 245, which extend towards each other. The first connecting plate 244 has two first connecting portions 2441, and the second connecting plate 245 has two second connecting portions 2451. The first heating element 21 includes two connecting ends 211 that can be electrically connected to switching components such as the relay 30. The second heating element 22 includes two connecting ends 221 that can be electrically connected to switching components such as the relay 30. The connecting ends 211 are accommodated in the first connecting portions 2441 and electrically connected to the relay 30, and the connecting ends 221 are accommodated in the second connecting portions 2451 and electrically connected to the relay 30.

[0064] In one embodiment, the length of the first heating element 21 is greater than the length of the second heating element 22. Therefore, the first heating element 21, which has low resistance, can also have high heating efficiency. It is understood that the length of the second heating element 22 can also be set to be greater than the length of the first heating element 21.

[0065] The first heating element 21 is generally annular, elliptical, square, hexagonal, triangular, or irregular in shape. The two connecting ends 211 of the first heating element 21 are separate from each other and extend toward the first connecting portion 2441. The second heating element 22 is also generally annular, elliptical, square, hexagonal, triangular, or irregular in shape. The two connecting ends 221 of the second heating element 22 are also separate from each other and extend toward the second connecting portion 2451. The first heating element 21 is arranged around the second heating element 22, and the two connecting ends 221 are located on the side of the first heating element 21 away from the connecting ends 211 to prevent short circuits caused by incorrect contact of the wires and to increase the operating space for connecting the wires to the ends.

[0066] The sidewall 2403 includes a first step 2406 and a second step 2407, both of which are arranged along the inner surface of the sidewall 2403. A first cover 23 is disposed on the first step 2406, and a second cover 25 is disposed on the second step 2407. The first cover 23 has notches 233 and 234, and a first connecting plate 244 and a second connecting plate 245 are respectively accommodated in notches 233 and 234.

[0067] The evaporation assembly 20 also includes a plurality of positioning portions 247, which may be positioning rods or positioning posts. The plurality of positioning portions 247 are disposed on the second guide portion 246, the intermediate wall 2404, the first receiving member 241, and the second receiving member 242. In one embodiment, the positioning portion 247 is accommodated in the second through hole 251 of the second cover 25, and at least one positioning portion 247 does not completely fill the corresponding second through hole 251; that is, there is a gap between the outer wall of at least one positioning portion 247 and the inner wall of the corresponding second through hole 251, allowing steam generated in the first sub-evaporation chamber 2401 and the second sub-evaporation chamber 2402 to flow through the gap. In another embodiment, the positioning portion 247 is accommodated in the second through hole 251 of the second cover 25, and the positioning portion 247 completely fills the second through hole 251, preventing steam generated in the first sub-evaporation chamber 2401 and the second sub-evaporation chamber 2402 from flowing out through the second through hole 251. In another embodiment, some positioning parts 247 are accommodated in the second through hole 251, and some positioning parts 247 are accommodated in the third through hole 252. The second through hole 251 is either completely filled or not completely filled by the positioning parts 247, and the third through hole 252 is not completely filled by the positioning parts 247. The steam generated in the first sub-evaporation chamber and the second sub-evaporation chamber can flow through the third through hole 252.

[0068] The evaporation assembly 20 also includes an outer cover 26, which has multiple first outlets 261 and second outlets 262. In one embodiment, the diameter of the first outlets 261 is approximately 10-20 mm, and the diameter of the second outlets 262 is approximately 40-80 mm. Several third through holes 252 in the middle portion of the second cover 25 correspond to the second outlets 262, and the remaining third through holes 252 correspond to their respective first outlets 261. Specifically, three third through holes 252 in the middle portion of the second cover 25 correspond to the second outlets 262, and the remaining third through holes 252 correspond to their respective first outlets 261. In one embodiment, the third through hole 252 has the same diameter as the second through hole 251. The positioning part 247 includes a plurality of first positioning parts and a plurality of second positioning parts. The first positioning parts are accommodated in the corresponding second through holes 251, connecting the cover 25 to the evaporation chamber 24. The size of the first positioning part is equal to or slightly smaller than the size of the second through hole 251. The second through hole 251 is filled by the corresponding first positioning part, or there is a small first gap between the inner walls of the first positioning part and the second through hole 251, through which the steam generated by the first sub-evaporation chamber and the second sub-evaporator can flow out. The size of the first positioning part may also be slightly larger than the size of the second through hole 251, and the first positioning part is interference-fitted with the second through hole 251. The size of the second positioning part is smaller than the size of the third through hole 252. The second positioning part is accommodated in the corresponding third through hole 252, and a second gap is formed between the second positioning part and the inner wall of the third through hole 252, through which the steam generated by the first sub-evaporation chamber and the second sub-evaporator can flow out.

[0069] The garment steamer 100 also includes a microcontroller 50 and a water pump 60 electrically connected to the microcontroller 50. The water pump 60 delivers water from the water tank 14 to the evaporation chamber 24. The water pump 60 is equipped with a motor, and the microcontroller 50 can control the pumping speed of the water pump 60 to regulate the steam output. The water pump 60 has relatively low power, approximately 1-10W. The low-power water pump 60 is small in size, suitable for a handheld garment steamer 100. The garment steamer 100 also includes a step-down module 70 electrically connected to the microcontroller 50, which reduces the 220V input voltage to a suitable operating voltage for the low-power water pump 60. The step-down module 70 can be an AC-DC step-down transformer. In one embodiment, the step-down module 70 can be integrated into a PCB board 40. In another embodiment, the step-down module 70 and the PCB board 40 are two separate components, with the step-down module 60 disposed on and electrically connected to the PCB board 40.

[0070] High-power water pumps are typically larger, occupying more internal space in the garment steamer 100, and require a 220V power supply to operate properly. Low-power water pump 60, on the other hand, is smaller and operates well with a 110V power supply. When the garment steamer 100 is connected to a 220V power supply, the step-down module 70 reduces the input voltage (220V) to a level suitable for the operating voltage of the water pump 60. In this way, the water pump 60 can operate well regardless of whether the garment steamer 100 is connected to a 110V or 220V power supply without increasing the size of the garment steamer 100.

[0071] The garment steamer 100 also includes a first connecting pipe 143 connecting the water tank 14 to the water pump 60 and a second connecting pipe 144 connecting the water pump 60 to the evaporation assembly 20. The water tank 14 includes a first part 141 and a second part 142, which are closedly connected to form a water storage space. The first connecting pipe 143 extends into the water storage space. The water pump 60 is located above the water tank 14, and the first connecting pipe 143 and the second connecting pipe 144 are respectively connected to both sides of the water pump 60.

[0072] The garment steamer 100 also includes a first thermostat 81 and a second thermostat 82. The first thermostat 81 detects a first temperature of the evaporation assembly 20. When the first temperature exceeds a first preset temperature, the first thermostat 81 disconnects the evaporation assembly 20 from the power supply. The second thermostat 82 detects a second temperature of the evaporation assembly 20. When the second temperature reaches a second preset temperature, the second thermostat 82 controls the water pump 60 to deliver water from the water tank 14 to the evaporation assembly 20. The rear cover 27 includes a mounting portion 271 for mounting the first thermostat 81 and the second thermostat 82. A second connecting pipe 144 passes through the mounting portion 271 to communicate with the evaporation chamber 24. In one embodiment, the first thermostat 81 has a normally closed switch, while the second thermostat 82 has a normally open switch.

[0073] The garment steamer 100 also includes a housing 10, a switch 124 disposed on the housing 10, a display panel 126 disposed on the housing 10, at least one button 127 disposed on the display panel 126, a PCB board 40, a fuse 83, and a plug 123 electrically connected to the PCB board 40. The water tank 14 may be partially exposed from the housing 10.

[0074] The housing 10 includes a first sub-housing 11, a second sub-housing 12 connected to the first sub-housing 12, and a third sub-housing 13. The third sub-housing 13 houses a portion of the structure of the relay 30, the PCB board 40, the microcontroller 50, and the evaporation assembly 20.

[0075] The first sub-casing 11 includes a support portion 111 for supporting the water tank 14, a receiving portion 112 for accommodating part of the water tank 14, and a first mounting portion 113. The second sub-casing 12 has a fourth through hole 1201 for exposing the switch 124 and a fifth through hole 1203 through which the power supply wire 122 passes, and a plug 123 is connected to the wire 122. The garment steamer 100 is connected to a power source via the wire 122 and the plug 123. The second sub-casing 12 also includes a second mounting portion 1204, on which the water pump 60 is mounted.

[0076] The third sub-shell 13 includes a first accommodating cavity 130, a sixth through hole 131, a second accommodating cavity 132 communicating with the first accommodating cavity 130 through the sixth through hole 131, a seventh through hole 133, and a channel 134 communicating with the second accommodating cavity 132 through the seventh through hole 133. The first accommodating cavity 130 accommodates part of the structure of the evaporation assembly 20. The second accommodating cavity 132 accommodates a relay 30, a PCB board 40, and a microcontroller 50. A second connecting pipe 144 passes through the channel 134, the second accommodating cavity 132, and the first accommodating cavity 130 and communicates with the evaporation chamber 24.

[0077] Reference Figure 14 The second embodiment of the present invention provides a garment steamer 100'. The garment steamer 100' has a similar structure to the garment steamer 100, but the differences include at least the following: the garment steamer 100' further includes a high-power water pump 62', which can operate normally under a 220V power supply; the power of the high-power water pump 62' is approximately 11-24W; both the high-power water pump 62' and the low-power water pump 60' are electrically connected to a relay 30' and connected to the evaporation assembly 20'; one microcontroller 50' controls the pumping speed of the low-power water pump 60', and another microcontroller 50' controls the pumping speed of the high-power water pump 62' to adjust the steam output.

[0078] The first switch 31' of relay 30' is connected by default to the first heating element 21' and the low-power water pump 60'. When the garment steamer 100' is connected to a power source with a voltage lower than 176V, the magnetic force generated by relay 30' is too weak to move the first switch 31' to connect it to the second heating element 22' and the high-power water pump 62', and the first switch 31' remains connected to the first heating element 21' and the low-power water pump 60'. When the garment steamer 100' is connected to a power source with a voltage not lower than 176V, the magnetic force generated by relay 30' can move the first switch 31' within approximately 20ms, connecting it to the second heating element 22' and the high-power water pump 62'. Thus, regardless of whether connected to a 110V or 220V power source, the garment steamer 100' can operate safely while generating a constant output without user intervention.

[0079] The first temperature controller 81' is used to detect the first temperature of the evaporator assembly 20', and when the first temperature exceeds the first preset temperature, the first temperature controller 81' disconnects the evaporator assembly 20' from the power supply. The second temperature controller 82' is used to detect the second temperature of the evaporator assembly 20', and when the second temperature reaches the second preset temperature, there are two second temperature controllers 82', which respectively control the high-power water pump 62' and the low-power water pump 60' to deliver water to the evaporator assembly 20'.

[0080] refer to Figure 15 The third embodiment of the present invention provides a garment steamer 100". The garment steamer 100" has a similar structure to the garment steamer 100, but the differences include at least the following: the switching component of the garment steamer 100" includes a detector 91" and a silicon controlled rectifier (SCR) 92" which is electrically connected to the detector 91". The detector 91" detects the voltage of the power supply, and the SCR 92" can automatically connect the first heating element 21" and the low-power water pump 60" to a 110V power supply, or automatically connect the second heating element 22" and the high-power water pump 62" to a 220V power supply, based on the detection result. In this way, regardless of whether the garment steamer 100" is connected to a 110V or 220V power supply, the garment steamer 100" can operate safely while generating a constant output without requiring additional user intervention.

[0081] refer to Figure 16 The fourth embodiment of the present invention provides a garment steamer 100”'.
