Abstract

PURPOSE:To provide a heating cooking device which has high waterproofness and high moisture resistance by providing a filter which passes waterdroplets but does not pass a voice between a voice radiation port of an operation panel and a loudspeaker. CONSTITUTION:A filter 10 which has fine pores of approx. several microns is interposed between a voice radiation port 7 of an operation panel 3 and a speaker 8. Since the size of the water droplet is approx. 100- several 1,000 microns, the filter 10 does not pass the droplets, with the result that the speaker 8 is not moistened. Accordingly, the normal speaker 8 which has low moisture resistance and a low cost can be used to provide high economy.

Description

DETAILED DESCRIPTION OF THE INVENTION The industrial field of invention relates to a cooking appliance equipped with a loudspeaker, such as a gastric frequency heating device equipped with a sound generating device.

Conventional configurations and their problems In recent years, it has become easier to use voice commands to control the equipment itself or use 11V.
! With the development of a system for informing the user of how to use the device, a heating control device using a loudspeaker (hereinafter referred to as a speaker) has been produced. Cooking appliances equipped with sound generating devices, such as microwave ovens, are used in environments that are completely different from those of conventional chimps and radios, so they exceed the durability and performance that have traditionally been required. is now required.

FIG. 1 is a diagram showing the outer assembly of a conventional microwave oven. 1st
In the figure, 1 is a closed door, and 2 is a door that can be opened and closed. 3
is an operation control panel provided on the front of the main unit, and a display section 4, a timer 5, a keyboard 6I, and a voice control panel 4 are arranged as shown in the figure. FIG. 2 is a sectional view showing a conventional speaker mounting structure.

In FIG. 2, a speaker 8 is fixed to the operation panel 3 with a metal fitting and can be removed. Because of this 4H configuration, water easily enters the entire audio radiation hole 7. Therefore, the conventional speaker 8 needs to be an expensive speaker 8 that has been subjected to moisture-proof treatment so that it can withstand even if it gets wet with water, resulting in poor economic efficiency. Further, in the case 1 in which several speakers are placed on the bottom surface as shown in FIG. 3, there is a drawback that it is difficult to hear the sound because the direction of sound emission is downward.

OBJECTS OF THE INVENTION The present invention (d, g) aims to solve the problems of the prior art, and provides a thermal cooker equipped with an excellent loudspeaker that is cheaper and can maintain the performance of the speaker itself. .

Structure of the Invention In order to achieve the above object, the present invention (d) provides a filter between the sound emitting port of the operation pile provided on the 11th side of the main body and the loudspeaker, which does not allow water bottles to pass through but allows sound to pass through.

Explanation of 11 Iq examples An embodiment of the invention will be described below with reference to the drawings.

FIG. 4 is a partial sectional view showing a state in which a speaker is attached through a filter having an inventive small opening 1.

In FIG. 4, like the conventional example, 3 is an operation panel, and 7 is a sound emission port provided on the operation panel. Reference numeral 8 denotes a speaker provided inside the body, and is fixed with a metal fitting 9.

Reference numeral 10 denotes a filter with an uninvented minute aperture, which is disposed between the sound emission lower and the speaker 8.

The size of the apertures of the filter 10 is approximately several ε microns, and the smaller the apertures, the smaller the interval between the apertures. Therefore, although it is thought that the sound volume is reduced by interposing the filter 10, there is no problem in actual use.

According to the second example, the following effects can be expected.

(1) Heating control! l! 5 is installed in the kitchen and is wet with water. Naturally, the speaker 8 is required to be output through the sound emitting port γ of the operation panel 3, so it is necessary to have a high performance level. Although a high-quality speaker 8 was used, a filter 10 with an aperture as small as several microns was interposed between the sound emission lower part of the water droplet 3 and the speaker 8, and on the other hand, the thickness of the water droplet was Since the water droplet is on the order of 100 to several thousand ε chromons, it is no longer possible to use the Itoyoshika speaker 8 in which the filter 10 does not collect any water droplets. Therefore, 1lli, I general safety 1 with low humidity performance.
It is highly economical to use a loud speaker 8.

(2) Since the sound is emitted from the front of the main unit, it is no longer difficult to hear the sound due to downward radiation as in the conventional example shown in Fig. 3.
There will be no more mistakes such as poor results.

(3) Conventionally, if you mistakenly insert an object such as chopsticks or a metal scale into the tip of the sound emitting lower, the speaker 8
However, since the filter 1o is provided in the present invention, the speaker 8 will not be damaged even if it is inserted once.

(4) If the speaker 8 is visible from the front, the appearance will look bad and the product value per song will decrease, but as a result of providing the filter 10 with a small opening, the speaker 8 cannot be seen.
A product with a good appearance due to its structure.

Effects of the Invention According to the second invention, the performance of the loudspeaker main body can be maintained by the filter having minute openings.
l'! l! B: It is possible to provide a heating cooker that can be used in a harsh environment using water.

Claims (1)

[Claims] A filter that is equipped with a loudspeaker on an operation panel provided on the front side of the main body, is provided with a sound emission port for emitting the sound of the loudspeaker, and has a minute opening of 100 microns or less between the loudspeaker and the sound emission port. A heating cooker configured to intervene.
