JP 2007-127365 A (Claim 6, paragraph 0032)

  In the above-mentioned conventional one, since the touch sensor is installed on the lower surface of the glass top plate, the upper surface of the top plate is completely flat. Although it is excellent from the viewpoint of design, if spillage occurs from a cooking utensil such as a pan placed on the heating part, and the liquid material flows out on the top plate, the liquid is in the range where the touch sensor is provided. Things can flow. In the above-mentioned conventional device, since the touch sensor is an electrostatic type, even if the liquid material spreads on the top plate and the liquid material covers the top plate, the touch sensor is touched in a dry state. There is a possibility that it may change differently from the change in capacitance in the state, and it is considered that malfunction may occur at the time of adjusting the heating power, or the heating power cannot be adjusted at all. Further, if the liquid material is not transparent, the display on the top plate cannot be seen by covering the top plate, and there is a problem that the position to be touched is not known.

  Then, this invention makes it a subject to provide the stove apparatus which can operate an operation button reliably, even if a liquid substance flows out on a top plate in view of said problem.

  In order to solve the above problems, a stove device according to the present invention has a horizontal top plate made of glass on an upper surface, and a touch unit for touch-operating a touch sensor type operation switch is provided on a part of the top plate. The stove apparatus is characterized in that the touch portion is raised from the other flat portion of the top plate so that the upper surface of the touch portion is higher than the upper surface of the top plate.

  The touch unit may be formed integrally with the top plate, but the top plate may be formed of a flat plate, and a touch piece may be attached to a position to be the touch unit to form the touch unit.

  In addition, the touch piece is made of a transparent member, and if the characters and symbols displayed on the touch portion can be identified through the touch piece in a state where the touch piece is attached to the touch portion, there is no touch piece. It is easy to apply to things.

  In addition, if the center of the upper surface of the touch part is the highest and gradually decreases as it moves away from the center, even if the liquid drops on the touch piece, it does not stay on the touch piece and always exposes the operation switch. be able to.

  Furthermore, if the upper surface of the touch part is formed in a convex lens shape, characters and symbols displayed on the touch part can be shown larger.

  By the way, when the touch part is provided in a plurality of places and the touch part is formed by a touch piece, the plurality of touch pieces to be attached to the top plate may be color-coded according to the operation content of the touch part. This makes it easy to distinguish.

  As is clear from the above description, the present invention provides an operation button that protrudes upward from the top plate, so that even if the liquid material drops on the operation button, the liquid material does not stop on the operation button and is always operated. Can be exposed. Further, even when the liquid material flows out on the top plate due to spilling and the liquid material spreads to the range where the operation buttons are provided, the operation buttons can continue to be exposed without being submerged in the liquid material. Therefore, the position of the operation button can be recognized and operated even when the liquid material is opaque.

  Referring to FIG. 1, reference numeral 1 is an example of a stove device according to the present invention. In the present embodiment, the stove device 1 is of the IH type and is fitted from above into a rectangular window hole (not shown) formed in the countertop CT. The top plate 2 is exposed at the upper part of the counter top CT, and the main body 11 of the stove device 1 is suspended below the counter top CT.

  The top plate 2 is formed of a glass plate, and heating units 21 are set on the top plate 2 at three locations. A heating coil (not shown) for generating a heating magnetic field is disposed below each heating unit 21. When a cooking utensil such as a pan is placed on the heating unit 21, the heating plate 21 is placed inside the bottom plate of the cooking utensil. An induced current is generated to heat the bottom plate itself.

  An operation button for switching the on / off state corresponding to each of the heating units 21 and an operation button group 3 for increasing / decreasing the heating power are provided on the top surface of the top plate 2.

  2 and 3, the button group 3 is provided with an operation button 31 for switching an on / off state and an operation button 32 for adjusting the thermal power. The operation button 31 is described as an example. A transparent touch piece 31a formed separately from the top board 2 is attached to the upper surface of the flat top board 2, and the upper surface of the touch piece 31a is the top board. It protruded above 2. A touch sensor terminal 31b on the substrate 12 is disposed below the touch piece 31a via the top plate 2. When the touch piece 31a is touched with a finger, the touch sensor terminal 31b senses the touch and heats it up. Energization to the heating stove provided in the unit 21 is started, and the energization is stopped when the touch piece 31a is touched again.

  Since the above configuration is adopted, for example, even when a water drop D is dropped on the operation button 31, the water drop D does not stay on the upper surface of the operation button 31, but flows down along the upper surface of the touch piece 31a and falls. Move to the top of 2. Further, even if a large amount of liquid material spills from the cooking utensil and spreads on the top surface of the top plate 2, the most part of the operation buttons 31 will be located above the draft WL and will not be submerged in the draft WL. .

  Further, although the operation button 31 has been described as an example, since the same configuration is adopted for the operation button 32, the same effect can be obtained for the operation button 32.

  As shown in FIG. 2, when the touch piece 31a is viewed from above, a display of “ON” can be visually recognized. This display is printed on the top surface of the top plate 2. When a transparent touch piece 31a is attached so as to cover the printed display, the display can be seen through the touch piece 31a. In addition, since the touch piece 31a acts as a convex lens, even if the display size printed on the top surface of the top plate 2 is relatively small, the touch piece 31a can be enlarged and visually recognized by the touch piece 31a.

  If the display is printed on the top surface of the top plate 2 in this way, the stove device of the present invention can be obtained by adding the touch piece 31a using a conventional existing top plate. However, the present invention is not limited to the form in which the display is printed on the upper surface of 2.

  For example, as shown in FIG. 4, the display may be printed on the upper surface 31aT or the lower surface 31aB of the touch piece 31a. When the touch piece 31a is shaped with resin, the printed matter 31aM may be cast into the touch piece 31a.

  Regardless of the position of the display, the touch piece 31a itself may be colored so that it can be distinguished from other touch pieces. Alternatively, the display may be formed of a fluorescent material, and the display itself may emit light by applying ultraviolet rays from below the top plate 2.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
