Description

Technical Field

[0001] The utility model belongs to the field of temperature control of handheld garment steamers, in particular to a temperature control system of a handheld garment steamer with a thyristor as a temperature control element. Background Art

[0002] A handheld garment steamer is a portable household appliance used to remove wrinkles and iron clothes. When in use, the handheld garment steamer needs to heat water to generate steam through a heating element to perform ironing operations. Existing handheld garment steamers have two heating methods: a ceramic temperature switch plus a series circuit and a PCB circuit board plus a relay plus an NTC temperature control probe.

[0003] When using the heating method of ceramic temperature switch plus series circuit, since the ceramic temperature switch has a fixed selection temperature, when the temperature switch senses that the temperature has been reached, the temperature switch will be disconnected, and the heater will stop heating at this time. When the temperature drops to the set value, the ceramic temperature switch will restart, and the heater will be powered on again to start heating. As a result, the steam is intermittent during the period when the ceramic temperature switch is disconnected. Although the heating method of series circuit and PCB circuit board plus relay plus NTC temperature control probe is more accurate than the ceramic temperature switch in temperature control, and multiple temperature gears can be set, it still controls a temperature range, and there is still the problem of intermittent steam.

[0026] like Figure 1-7 As shown, after the PCB circuit board 201 is powered on, the thyristor element 202 is started. When the temperature control probe 203 reaches the set temperature, the water pump 302 starts to work. The water pump 302 guides the water in the inner cavity of the water tank 301 to the inner cavity of the heat sink 303 through the water inlet 304, the water inlet pipe 306 and the water outlet pipe 307. The inner cavity of the heat sink 303 is provided with a water channel. After the water enters the inner cavity of the heat sink 303, it flows along the water channel to take away the heat generated by the thyristor element 202, thereby cooling the thyristor element 202. The water in the inner cavity of the heat sink 303 is provided with a water channel. The water enters the ironing component 1 through the water outlet 305, and is heated by the cast aluminum heater 205 to become steam.

After the PCB circuit board 201 is powered on, the thyristor element 202 is started. The thyristor element 202 controls the wattage of the cast aluminum heater 205 by adjusting the output current. When the temperature is about to reach the set temperature, the input current is reduced, and the wattage of the cast aluminum heater 205 is automatically adjusted, so that the temperature of the cast aluminum heater 205 will slowly reach the set temperature, thereby preventing the steam from being intermittent. Water enters the inner cavity of the first guide groove 108 through the water inlet 107, flows along the inner cavity of the first guide groove 108, and then enters the inner cavity of the second guide groove 109 through the guide hole 110, and flows along the inner cavity of the second guide groove 109.

The water in the inner cavity of the heat sink 303 is diverted to the water inlet hole 107 through the water outlet 305 and enters the inner cavity of the first guide groove 108. The water can be heated by the temperature control component 2 to generate steam. When the water passes through the heat sink 303, it is equivalent to preheating the water.

The water pump 302 guides the water in the inner cavity of the water tank 301 through the water inlet 304, the water inlet pipe 306 and the water outlet pipe 307 to the inner cavity of the heat sink 303. The inner cavity of the heat sink 303 is provided with a water channel. After the water enters the inner cavity of the heat sink 303, it flows along the water channel to take away the heat generated by the thyristor element 202, thereby The thyristor element 202 can be cooled down. The water in the inner cavity of the heat sink 303 is guided to the water inlet 107 through the water outlet 305, enters the inner cavity of the first guide groove 108, flows along the inner cavity of the first guide groove 108, and then enters the inner cavity of the second guide groove 109 through the guide hole 110, flows along the inner cavity of the second guide groove 109. The cast aluminum heater 205 can heat the water in the inner cavities of the first guide groove 108 and the second guide groove 109 to generate steam and spray it to the outside through the spray hole 104, so that ironing operation can be performed.
