Abstract

PURPOSE:To minimize the size of a cooker by mounting an ordinary type of speaker facing downward on the surface of the bottom inside a cooker thereby protecting the speaker inspite of the adverse condition using heat and water. CONSTITUTION:A control part 3 comprising an indicator tube 4, a timer 5, a menu selector 6 is provided on the right side surface of a door 2 of a high frequency heating device. A vacant part that houses various controlling parts is provided at the right side of an oven. Numerous sound passing holes 11 are punched on the bottom 8 of the above mentioned vacant part. A speaker 10 is mounted facing downward on the surface with holes. With this construction, an ordinary type of speaker 10 can be used despite the adverse operating environment unfavorable for an electronic equipment.

Description

DETAILED DESCRIPTION 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.

Conventionally, in many cases of devices that emit sound, such as radios and televisions, the sound emission direction has been located in front of the main body of the device. On the other hand, in products aimed at downsizing the main body of the device, the sound emission direction is sometimes located on the top surface of the device or on the 1j surface due to limited mounting space. In addition to these devices with a general configuration, in recent years a system has been developed that uses audio to inform the user of how to operate or handle the machine itself. Equipment used 7! l; The trend of increasing power dramatically, not only in television and radio, is becoming evident. Equipment equipped with such a sound generator,
For example, cooking appliances such as microwave ovens are used in a completely car environment unlike conventional televisions and radios, so they are now required to have more durability and performance than conventionally required. ,.

For example, in a microwave oven, the speaker power; when used, the front of the appliance is mostly occupied by the cooking chamber and its door, and the other part is the power applied to the operating section; this operating section is the display tube that displays the time, the menu The current situation is that there is not enough space on the front of this device to mount a speaker, since there are switches to select the heat source, a timer to input the heat time, etc. Therefore, it has been considered to orient the sound emission direction to the front of the appliance, as seen in conventional configurations such as TVs and radios, but since cooking appliances often use water etc., the top of the appliance If water or the like spills on the device, it is highly likely that the speaker will get wet.

Furthermore, in general, in a heating cooker, the upper part of the appliance does not reach a high temperature, which creates harsh operating conditions for the speaker, and there has been a demand for the development of a speaker that can withstand these operating conditions. However, if the speaker is constructed to withstand the harsh operating conditions mentioned above, it will increase the manufacturing cost of the unit and complicate the mounting configuration.
This caused an increase in the installation space, resulting in an increase in the size of the heating cooker itself and an increase in cost.

The present invention aims to solve the above conventional problems, and provides a cooking appliance equipped with an excellent loudspeaker that makes effective use of limited space, is inexpensive, and maintains the performance of the speaker itself. , is a thing.

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

FIG. 1 shows a high-frequency heater with a sound generator.

A door 2 is provided in the front of the cooking cabinet 1 so that it can be opened and closed freely.
An operating section 3 is formed on the front right side of the screen. Said operation section 3
Display tube 4. A timer 6° menu selection switch 6, etc. are arranged as shown. An electric heater 7 is installed inside the cooking cabinet 1 by penetrating the wall of the cooking cabinet 1. Inside the appliance on the right side of the cooking cabinet 1, a space is provided in which various control parts are arranged. Legs 9 are attached to the bottom plate 8 of the appliance, and the legs 9 form an air supply space between the bottom plate 8 of the appliance and the floor surface, and necessary outside air is supplied from the air supply space. It also prevents equipment from getting dirty from moisture on the floor. As shown in FIG. 2, a speaker 1o is mounted on the bottom plate 8 of the device with its sound emission direction facing downward, and the bottom plate 8 of the device corresponds to the sound emission direction of the speaker 1o.
A large number of punching holes 11 are provided in the portion to facilitate the passage of sound. The speaker 1o is screwed to the bottom plate 8 by a locking tool 12.

With the above configuration, the following effects can be obtained.

(1) The part of the dead space in the space where the various control parts of the appliance are installed can be effectively used as a speaker installation space, so there is no need to increase the external dimensions of the appliance itself, and it does not require the use of a conventional sound generator. The dimensions can be the same as those without.

(2) Since the space is surrounded on all sides by the outer case, there is no risk of water entering. Furthermore, since the speaker 1o is attached to the bottom plate 8 facing downward, water flowing down through the outer case will not flow down to the speaker 10.

Furthermore, the bottom plate 8 is located at the lowest position of the device, and the speaker 1
The temperature around 0 is the lowest in the instrument.

(3) Even if a foreign object is inserted from the outside, for example, a rod-shaped object is inserted by mistake, the speaker 10 is installed in the space, on the bottom surface 8 of the desk, so it is in the place that is most difficult to reach from the outside. , the diaphragm of the speaker 10 is destroyed,
It can prevent damage caused by mischief.

4. Since the space in which the speaker 1o is installed functions as a speaker box that makes the sound of an audio device louder, the volume can be adjusted without requiring any special configuration.

Both sound quality and speaker performance can be maintained.

Another embodiment of the invention is shown in FIG.

In this embodiment, there are punched holes 1 on the lower surface of the bottom plate 8 of the instrument.
A reflecting plate 13 having a bent surface inclined at approximately 46° with respect to the reflecting plate 13 is provided. The reflecting plate 13 may be a press-molded metal plate or a molded resin plate. With such a configuration, the sound from the speaker 1o can be reflected to the front side of the device, giving strong directivity to the front side, so that the user can hear the sound clearly.

As described above, the present invention has a structure in which the loudspeaker is attached to the mounting surface provided on a part of the bottom plate of the device with its sound emission direction facing downward, so that a new sound emitting part is added to the front or side of the device. There is no need to provide a device, the limited space of the device can be effectively utilized, and the device dimensions can remain the same as conventional ones. The original performance of the loudspeaker is maintained without the need for a special loudspeaker, and the loudspeaker is highly durable and economical for appliances that are still used in harsh environments such as cookers due to heat, water, etc. It is possible to provide a cooker equipped with a container.
