Hereinafter, a control panel assembly of a range hood system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 to 5, the control panel assembly 10 proposed by the present invention is applied to the range hood system 1 to thereby control the range hood and the like.

Such a range hood system has a conventional structure, for example, a gas cook 3 serving as a heat source; A range hood 5 for discharging the odor or smoke generated from the gas cooker 3 to the outside; And a gas valve 7 for supplying / blocking gas to / from the gas cooker 3.

In such a range hood system, the control panel assembly 10 is mounted on a range hood or the like.

More specifically, the control panel assembly 10 includes a cover 16 disposed on the front surface thereof as conductive acrylic, a switch film 17 formed on the rear surface of the cover 16, and a conductive layer formed on the PCB When the user touches the cover 16 by arranging the gasket 19, an electric signal is transmitted to the PCB, so that the menu is operated.

That is, the control panel assembly 10 includes a case 12; A PCB 14 disposed inside the case 12; A light-transmitting cover (16) mounted on a front surface of the case (12) to seal the front space and having conductivity; A switch film (17) integrally formed on a rear surface of the light-transmissive cover (16); A gasket (19) disposed on a front surface of the PCB (14) and on which a conductive layer is formed; And male and female engaging portions 18 for male and female engaging the case 12 and the light-transmissive cover 16.

In the control panel assembly 10 having such a structure, the case 12 forms an outer appearance, and a plurality of support protrusions 28 protrude from the inside. The PCB 14 can be seated on the support protrusion 28 by being fixed by a fastening member such as a screw.

Various circuits for operating the cooking hood are disposed on the PCB 14, and a conductive gasket 19 is mounted on the circuit. In this case, the conductive gasket 19 serves as a switch for electrically turning on / off each circuit, so that when the light-transmitting cover 16 is touched, each circuit on the PCB 14 is turned on when an electric signal is transmitted, (Off).

At this time, the conductive material constituting the gasket 19 may be composed of various components, for example, by coating or mixing the conductive polymer.

Alternatively, a coating layer may be formed on the surface of the gasket 19 by a conductive transparent electrode such as ITO (Indium Tin Oxide), which is a conductive compound of indium and tin oxide.

Therefore, when the user touches the conductive light-transmitting cover 16, an electric signal is transmitted to the conductive gasket 19 so that the corresponding circuit of the PCB can be operated.

In the above description, a coating layer of a conductive material is formed on the gasket to transmit an electric signal. However, the present invention is not limited to this, and an electric signal can be transmitted also by a piezoelectric method.

That is, when the light-permeable cover 16 is pressed by arranging the piezoelectric element in the gasket 19, an electric signal is generated by the piezoelectric element.

The case 12 can be detachably coupled by male-and female coupling by the light-transmitting cover 16 and the female-male engaging portion 18.

That is, the male and female engaging portions 18 include a plurality of locking projections 22, 24 protruding forward from the rim of the case 12; The light-transmissive cover 16 is recessed along the rim 27 protruding from the rear surface of the light-transmissive cover 16 so that the light-transmissive cover 16 is detachably engaged with the case 12 by engaging the plurality of locking projections 22, And a storage chin 20.

In the male and female coupling portions 18 having such a structure, the plurality of locking projections 22 and 24 protrude from the rim of the case 12 and have a suitable elastic force in the vertical direction. That is, the latching protrusions 22 and 24 include a support 22 projecting forward from the rim; And a latching jaw 24 protruding from the distal end of the support table 22 and hooked to the receiving jaw 20.

The receiving jaw 20 may be formed by recessing the groove 29 in the outer surface of the rim 27 protruding inward from the rear surface of the light-transmissive cover 16. The plurality of locking protrusions 22 and 24 of the case 12 are caught by the receiving jaws 20 so that the light transmitting cover 16 Can be integrally coupled to the case 12.

At this time, the storage jaw 20 is not formed at a specific position but is formed along the rim 27 of the light-transmissive cover 16, so that the plurality of locking projections 22 and 24 are arranged at any positions of the rim 20 ). Therefore, the light-transmissive cover 16 can be easily coupled to the case 12 without considering the engagement position.

The length and width of the light-transmissive cover 16 are greater than the length and width of the case 18 so that the entire surface of the case 18 can be completely blocked, It is possible to prevent penetration into a clearance between the first and second electrodes.

Meanwhile, the light-transmissible cover 16 is formed of a transparent or semi-transparent material and includes acrylic having a conductive material.

Such a conductive acrylic has a certain level of conductivity by adding a substance having conductivity in the production of acrylic. For example, by adding a conductive polymer component to acrylic at a certain ratio.

Alternatively, a conductive transparent electrode such as indium tin oxide (ITO), which is a conductive compound of indium and tin oxide, may be coated on acryl.

Therefore, the conductive light-transmitting cover 16 is in a state in which electric charges are flowing, and as the body contacts, charges on the surface of the finger are collected opposite to the charge of the cover, so that the charge of the cover is slightly canceled and measured on the cover surface The electric field is weakened. This electrical change is transferred to the conductive gasket 19 so that the PCB can be driven.

The switch film 17 is integrally formed on the rear surface of the light-transmissive cover 16. At this time, the switch film 17 may be formed on the rear surface of the light-transmissive cover 16 by various methods, for example, by a printing method or by a film method. This can be selected appropriately according to the design of the control panel assembly. The switch film 17 also has a conductive material. Therefore, an electric signal generated when the light-transmitting cover is touched can be transmitted to the gasket 19 of the PCB 14 through the switch film 17. [

The switch film 17 is composed of various menu switches. For example, the switch film 17 may include various switches such as a hood air volume control switch, a hood light switch, a hood stop switch, and a timer.

At this time, since the light-transmissive cover 16 is made of a transparent material, the switch film 17 disposed on the inner side of the front surface of the light-transmissible cover 16 can be visually recognized.

Therefore, when the user wants to operate a specific switch on the switch film 17 on the front surface of the control panel, the capacitance of the region corresponding to the specific switch is changed by touching the light-transmissive cover 16, The function is activated by being transmitted to the gasket 19 of the PCB 14.
