Description

  The present invention relates to a stove apparatus including a top plate that transmits light, such as an IH stove that performs induction heating.

  In a stove apparatus using a gas burner, it is possible to easily identify that the gas burner is in operation because the flame can be visually observed in a state where it is added to the gas burner. On the other hand, in a stove device such as an IH stove, a cooking utensil is placed on a top plate that does not have an opening, and the cooking utensil is heated through the top plate. Therefore, there is a problem that it is difficult to identify whether the cooking utensil placed on the top plate is being heated.

  For this reason, in a stove device having a plurality of stove parts, an illuminating means is provided in the operating part of the operating stove part so that the operating part is illuminated so that it can be identified that the stove part is in operation Those are known (for example, see Patent Document 1).

In addition, there is also known an apparatus in which an annular light emitting portion is provided so as to surround the stove portion, and that the light emitting portion emits light while the stove portion is in operation to notify that it is in operation.
JP 2005-158329 A (Claim 7)

  In the above conventional apparatus, it is possible to easily identify whether or not the stove unit is operating when standing on the front of the stove apparatus. In such a state, the stove device is viewed obliquely laterally or at an angle close to horizontal, and even if a part of the top plate emits light or the operation unit is illuminated, there is a problem that it cannot be easily identified. .

  Then, this invention makes it a subject to provide the stove apparatus which can identify easily that a cooking utensil is heating, even if it does not stand in front of a stove apparatus in view of said problem.

  In order to solve the above-described problems, a stove device according to the present invention includes a top plate that transmits light, and in the stove device that heats a cooking utensil placed on the top plate, from below the top plate, Illuminating means for illuminating at least the side surface of the cooking utensil is provided.

  In the said structure, since the side surface of cooking utensils, such as a pan, is illuminated, it can identify easily that the cooking utensil is illuminated, even if it is not standing in front of a stove apparatus.

  If the surroundings are bright, it may be difficult to instantly recognize that the cooking utensil is illuminated. In such a case, the state of illumination by the illumination means may be changed with the passage of time during heating.

  In addition, you may change the state of the illumination by the said illumination means according to the thermal power in heating.

  As is clear from the above description, the present invention is that the cooking utensil is being heated even from a position away from the stove device as compared with the conventional one in which a part of the top plate emits light or the operation unit is illuminated. Can be identified, and the problem of forgetting that it is being cooked can be solved.

  Referring to FIG. 1, reference numeral 1 denotes a built-in type IH stove to which the present invention is applied. The IH stove 1 includes a glass top plate 11. This glass top plate 11 is transparent and can transmit light. On the top plate 11, two left and right IH heating units 2 for heating cooking utensils such as a pan by electromagnetic induction, and an infrared heating unit 3 for heating the cooking utensils with infrared rays emitted from a radiant heater are provided. .

  Referring to FIG. 2, induction coil 12 is disposed below IH heating unit 2. In addition, 13 is a magnetic-shielding material which prevents the leak of speed. In the present embodiment, the four light emitting diodes 4 are arranged below the balance 11 so as to surround the induction coil 12. The light emitted from the light emitting diodes 4 is set so as to pass through the top plate 11 and illuminate the side surface of the cooking utensil C placed on the top plate 11.

  When the cooking utensil C is placed on the left or right IH heating unit 2 and the heating switch is operated, the control unit (not shown) detects whether the cooking utensil C is actually placed on the IH cooking unit 2 The energization of the induction coil 12 on which the cooking utensil C is placed is started. Then, the light emitting diode 4 disposed around the induction coil 12 on the energized side is caused to emit light. Thereby, the side surface of the cooking utensil C being heated is illuminated with the light from the light emitting diode 4.

  When the heating time is longer than the predetermined time as in the case of stewed cooking, the lighting state is changed after the predetermined time is exceeded. Specifically, the illuminance of the light emitting diode 4 may be increased or decreased, or the plurality of light emitting diodes 4 may be blinked at different timings.

  Moreover, you may make it change the state of illumination suitably according to the output of the induction coil 12, ie, the magnitude of a heating amount. For example, the illumination color may be changed or the illuminance may be increased or decreased by using light emitting diodes of three primary colors.

  According to the above configuration, since it is possible to instantly recognize that the cooking utensil C is being heated even at a location away from the IH stove 1 during cooking, without forgetting that it is being heated, Moreover, if the state of illumination is changed according to a thermal power, a thermal power can also be recognized from the distant position.

  In the above description, the light emitting diode 4 is disposed in the IH heating unit 2, but the light emitting diode 4 may be disposed in the infrared heating unit 3 in the same manner. In addition, although a radial heater is used for the infrared heating unit 3, a halogen lamp or the like may be used. Furthermore, although the built-in type IH stove has been described in the above embodiment, the present invention can also be applied to a stationary type IH stove.

  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.
