Description

Technical Field

[0001] The utility model relates to the technical field of hand dryers, and particularly relates to an intelligent hand dryer. Background Art

[0002] A hand dryer is an essential household appliance in hotels and families, and its purpose is to quickly dry the hands after washing. In cold seasons, wet hands can bring a cold and uncomfortable feeling to people. If the warm hot air emitted by the hand dryer is used to dry the hands, it can not only relieve the cold feeling, but also improve the comfort of users at the same time.

[0003] Existing hand dryers can only be used for drying hands, and it is not very convenient to use them for drying other items. For example, when a user uses a hand dryer to dry wet clothes or shoes, the user needs to hold the clothes and shoes and keep them at the air outlet of the hand dryer. This will not only cause hand fatigue to the user, but also there is a risk of being scalded as the hands are exposed to hot air for a long time. Summary of the Invention

[0004] The technical problem to be solved by the utility model is the inconvenient situation when a hand dryer is used to dry other items.

[0005] To solve the above technical problem, the hand dryer is designed as a structure in which the hot air outlet component and the fixing rack are separable. When the use scenario is drying hands, the hot air outlet component is placed on the fixing rack, and at this time, the hot air outlet component and the fixing rack together form a hand dryer. When the use scenario is drying items, the user can remove the hot air outlet component from the fixing rack and press the button on the hot air outlet component to use it. And when the user puts the hot air component back on the fixing rack, there is no need for the user to manually switch the mode, and the hot air component intelligently switches to the hand drying mode.

[0006] The utility model provides an intelligent hand dryer, which includes a fixing rack and a hot air blower. The hot air blower includes a handle and an air outlet cylinder. The fixing rack includes an air outlet hole, a placement groove and a connection part. The hot air blower further includes a heater, a motor, a button, a human body induction sensor, an induction switch and a control module.

[0007] Further, the human body induction sensor and the induction switch are arranged on the air outlet cylinder.

[0008] Preferably, the human body induction sensor is an infrared sensor.

[0009] Further, the human body induction sensor includes a transmitter and a receiver.

[0010] Further, a bracket is arranged in the air outlet hole. The bracket includes a groove. A magnetic material is arranged in the groove.

[0011] Further, the connection part includes a slot.

[0012] Preferably, the induction switch is a Hall switch.

[0013] Further, the placement groove extends in a direction perpendicular to the center line of the air outlet hole.

[0014] Further, a circular groove is provided at the bottom of the fixing bracket. A metal ring is provided in the circular groove.

[0015] Further, an air duct member is provided in the air outlet hole. The air duct member includes a bottom surface. A first through hole is provided on the bottom surface. A first side wall extending upward is provided around the first through hole. Description of the Drawings

[0023] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0024] In the present utility model, unless otherwise clearly specified and defined, the terms "mounted", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0026] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element.

[0027] Referring to Figures 1 to 4 As shown, an embodiment of an intelligent hand dryer of the present utility model includes a fixing frame 1 and a hot air blower 2. The hot air blower 2 includes a handle 21 and an air outlet cylinder 22. The fixing frame 1 includes an air outlet hole 11, a placement groove 12 and a connecting portion 13. The hot air blower 2 further includes a heater 23, a motor 24, a button 25, a human body induction sensor 26, an induction switch 27 and a control module 28.

[0028] The human body induction sensor 26 and the induction switch 25 are disposed on the air outlet cylinder 22.

[0029] The human body induction sensor 24 is an infrared sensor and includes a transmitter 261 and a receiver 262.

[0030] A bracket 111 is disposed in the air outlet hole 11. The bracket 111 includes a groove 112. A magnetic material 113 is disposed in the groove 112.

[0031] The connecting portion 13 includes a slot 131.

[0032] The induction switch 25 is a Hall switch.

[0033] The placement groove 12 extends along the vertical direction of the center line of the air outlet hole 11.

[0034] An annular groove 29 is provided at the bottom of the fixing frame 1. A metal ring 291 is disposed in the annular groove 29.

[0035] A duct member 14 is disposed in the air outlet hole 11. The duct member 14 includes a bottom surface 141. A first through hole 142 is provided on the bottom surface 141. A first side wall 143 extending upward is provided around the first through hole 142.

[0036] The principle of the intelligent hand dryer to achieve intelligent switching between hand drying and object drying modes is as follows: When the hot air blower 2 is placed on the fixing rack 1, the control module 28 receives the signal sent by the induction switch 25. At this time, the control module 28 intelligently switches the mode to the hand drying mode. If the user places both hands under the air outlet 11, the control module 28 will receive the signal sent by the human body induction sensor 24. At this time, the control module 28 activates the hot air function. When the user removes both hands from under the air outlet 11, the human body induction sensor 24 will stop sending the signal. At this time, the control module 28 turns off the hot air function.

[0037] When the user removes the hot air blower 2 from the fixing rack 1, the induction switch 25 will stop sending the signal. At this time, the control module 28 intelligently switches the mode to the object drying mode. If the user presses the button 25, the control module 28 will operate according to the preset motor speed and heating power.

[0038] The above-described embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
