CONSTITUTION:A speaker 8 is provided within a main body 1 of the rear part of an operating panel 3. A waveguide 11 is provided between the speaker 8 and the operating panel 3. Electric parts such as a microcomputer, resistance and a condenser are provided on a control circuit board 12 controlling a heating period and a heating mode of a heating cooker. The control circuit board 12 is provided within the main body 1 of the rear part of the operating panel 3. Then, a voice emitting opening 8 is provided on the operating panel 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking appliance equipped with a loudspeaker, such as a high-frequency heating device equipped with a sound generating device.

Conventional configuration and its problems In recent years, systems have been developed that inform the user how to operate or handle the device itself by voice. Since cooking appliances equipped with sound generating devices, such as microwave ovens, are used in a completely different environment from conventional televisions and radios, this has traditionally been a small requirement. More than durability and performance are now required.

FIG. 1 is a diagram showing the appearance of a conventional microwave oven. 1st
In the figure, 1 is the main body, and 2 is a door that can be opened and closed.

3 is an operation panel provided on the front of the main body 1, and a display section 4
．． Timer 5. A keyboard 6 is arranged as shown in the figure. As described above, it is currently difficult to secure space for mounting a speaker on the operation panel 3. Therefore, as shown in FIG. 2, a speaker 8 was mounted on the bottom surface 7 of the main body. This conventional configuration has the disadvantage that it is difficult to hear the sound because the sound is emitted in a downward direction.

On the other hand, if a speaker is attached directly to the operation panel 3, it is necessary to use an expensive speaker that is thin and does not take up much installation space, and has been treated to be moisture-resistant so that it can withstand even if it gets wet. It had become a bad thing.

OBJECTS OF THE INVENTION The present invention aims to solve the above-mentioned conventional problems, and provides a heating cooker equipped with an excellent loudspeaker that is inexpensive and capable of maintaining the performance of the speaker itself.

Structure of the Invention In order to achieve the above object, the present invention provides an operation panel provided on the front of the main body with a sound emission port for radiating the sound of a loudspeaker, and a waveguide is provided between the loudspeaker and the sound emission port. It is something that

Description of examples An embodiment of the present invention will be described below based on the drawings.

FIG. 3 is an external perspective view showing a state in which a speaker is attached to the main body via the waveguide of the present invention.

In FIG. 3, reference numeral 9 denotes a heating chamber, and a speaker 8 is disposed within the rear main body 1 of the operation panel 3. speaker 8
The waveguide 11 of the present invention is disposed between the control panel 30 and the control panel 30 . 12 is a control board that controls the heating time and heating mode of the cooking device. A microcomputer is disposed on the control board 12, and the control board 12 is disposed within the rear main body of the operation panel 3.

FIG. 4 is a partial sectional view showing how the speaker 8 is attached.

In FIG. 4, 8 is a speaker, 11 is a waveguide, and 13 is a sound emission port provided on the operation panel 3.

The speaker 8 and the waveguide 11 are fixed by a screw 14 with a fastener 14.

FIG. 5 is an external perspective view of the waveguide 11.

The material of the waveguide may be resin or metal, and the material may be selected as appropriate depending on the shape.

According to the above embodiment, the following effects can be expected.

1. The direction of sound radiation is from the front of the main body through the waveguide 11, so there is no need to worry about the sound opening and jerking due to downward radiation as in the conventional example. 2. Raise the air in the heating chamber 9. In a cooking device that heats food, the atmosphere behind the operation panel 3 becomes high, and when directly attached to the operation panel 3, it is necessary to use an expensive speaker with a high heat resistance grade. However, by devising the shape of the waveguide 11 of the present invention, the speaker 8 can be installed at a location with a low temperature, so an inexpensive speaker 8 with a low heat resistance grade can be used, making it more economical. Since the heating cooker is installed in the kitchen, if it is operated with wet hands, the speaker will naturally get wet through the sound emission port of the operation panel 3, so an expensive speaker 8 with high moisture resistance was used. Since the waveguide 11 is interposed between the operation panel 3 and the speaker 8, the speaker 8 does not get wet as described above. Therefore, a general speaker 8 can be used, making it more economical.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the original performance of a loudspeaker can be maintained using a waveguide with a simple configuration, and it is also economically efficient in the harsh operating environment of a heating cooker due to heat, water, etc. A heating cooker equipped with a loudspeaker can be provided.
