Description

Technical Field

[0001] The present invention relates to the technical field of ironing machines, and in particular to an ironing machine. Background Art

[0002] Most of the irons / garment steamers on the market only have the steam generating function, and the research and development direction of the ironing machine / garment steamer manufacturers is basically centered around how to improve the heating efficiency or ensure product safety. Therefore, the ironing machines / garment steamers on the market now require two hands to operate when ironing and are easily burned.

[0003] In order to operate the ironing machine / hanging ironing machine more conveniently, technicians in this field began to add an adsorption function to the ironing machine. For example, the Chinese patent with patent application number "CN202122860516.1" and name "A Steam Brush" discloses that "when the steam brush irons clothes, the blowing and suction device sucks air, and the outside air enters from the first air outlet, so that negative pressure is formed at the first air outlet and the clothes are adsorbed. The user does not need to flatten the clothes by hand when ironing, so as to keep the clothes as flat as possible. At the same time, the heating element component heats the water from the water tank component into steam and sprays it from the steam outlet, so as to realize the ironing function of the steam brush on clothes. The working mode combining adsorption and ironing enables the user to operate the handheld steam brush with one hand to iron clothes. The operation is simple and easy to use."

[0004] However, this solution using an axial flow fan requires an additional motherboard to drive the fan because the working voltage of the fan and the working voltage of the heating element assembly are not in the same voltage range, so the cost is relatively high. In view of this, how to reduce the production cost of the ironing machine while achieving the adsorption function has become a technical problem that needs to be solved urgently by those skilled in the art.

[0100] The first end of the fuse 47 is used to electrically connect to the positive electrode of the power supply, the second end of the fuse 47 is electrically connected to the first end of the main heat pipe 41 and the first end of the auxiliary heat pipe 42 respectively, the first end of the main heat pipe 41 is electrically connected to the first end of the first temperature control switch KSD1, and the second end of the first temperature control switch KSD1 is used to electrically connect to the negative electrode of the power supply;

[0101] The second end of the auxiliary heat pipe 42 is electrically connected to the first end of the second temperature control switch KSD2, and the second end of the second temperature control switch KSD2 is electrically connected to the voltage stabilizing chip U3.

[0102] The second end of the second temperature control switch KSD1 is also electrically connected to the positive input end of the voltage stabilizing chip U3, and the negative input end of the voltage stabilizing chip U3 is electrically connected to the positive electrode of the diode D1; the output end of the voltage stabilizing chip U3 is electrically connected to the power interface of the brushless motor driving chip CN3, and the three-phase output ends of the brushless motor driving chip CN3 are respectively electrically connected to the corresponding three-phase wiring terminals on the fan 50.

[0103] It is understandable that the voltage regulator chip U3 and the brushless motor driver chip CN3 are both conventional components in this field. There are many product types, and users can select materials according to different needs or product types, which will not be elaborated here.

[0104] To make it easier to understand, here is how the ironing machine works:

[0105] When the user needs to use the ironing machine for ironing, the user presses the trigger 12 on the front shell 10 of the ironing machine to trigger the micro switch 121, and the main heat pipe 41 and the auxiliary heat pipe 42 start heating immediately. Then, the fan switch 22 (composed of a gear switch 221 and a switch cover 222) on the rear shell 20 is triggered to control the operation of the fan 50 to start the adsorption function. Figure 2 As shown, the above-mentioned case switches can be arranged on the button bracket 14, and the specific structure is not described here in detail;

[0106] When the steam generated by the heating body 44 is evenly sprayed out from the air jet port 211, the ironing operation can be carried out on the clothes to be ironed or the ironing objects. During ironing, the interior of the dust box 11 is in a negative pressure state, and the objects to be ironed will be adsorbed through the adsorption holes 111. The user does not need to position them by hand, so the user can operate it with one hand, which is very convenient. After ironing is completed, the entire ironing machine can be powered off by the trigger 12.

[0107] In summary, the present invention effectively reduces the production cost of the ironing machine while achieving the adsorption function.
