  However, this type of cooking device has a small hole in the wall so that the radio waves in the heating chamber do not leak outside, so the amount of incident light is small and the heating chamber often feels dark. However, recently, a device has been devised to increase the amount of light collected by arranging light sources at multiple points according to the pitch of the light-emitting holes from the light emitters of LEDs, but the light source is too strong, so the eyes of equipment users There was a problem of direct light entering and feeling dazzling.

  The present invention solves the above-described conventional problems, and an opaque sheet is attached to the small hole so that the light from the light source does not reach the eyes directly from the user. At this time, since the brightness in the warehouse is lowered, only the area where the lighting holes, light source positions, and door screens are arranged in a straight line, the past object is pasted, and the object to be heated is the light to be irradiated in the warehouse. The purpose is to provide a device that remains bright and does not give glare to device users.

In order to achieve the above object, the present invention has a heating chamber for heating an object to be heated, and a small hole portion formed on the wall surface of the heating chamber and provided with a plurality of small holes. In the heating and cooking device that performs, the plurality of light sources arranged outside the small hole portion are provided, and the shadow of the predetermined range in the heating chamber is eliminated regardless of the size and pitch of the small holes in the small hole portion. The light source is disposed and the sheet to be pasted in the small hole portion is continuously changed from transparent to opaque from the back of the heating chamber toward the front, and the light source is disposed in a direction in which the sheet is changed from transparent to opaque. On the other hand, it is arranged in a row at right angles, and the area is made clear by eliminating the shadow of a specific place, making it uniform brightness, and suppressing the glare of the user.

As a result, the opaque area that reduces glare on the user's light source can be reduced, and as a result, the transparent area of the sheet that illuminates the heating chamber is expanded, so that the brightness in the heating chamber can be maintained .

  In the present invention, even if the user looks into the heating chamber while using the device, the opaque sheet is attached so that the light from the light source of the device is not directly seen. Can be seen.

1st invention has the heating chamber which heats a to-be-heated material, and the small hole part which was formed in the said heating chamber wall surface, and provided with several small holes, The cooking which performs interior lighting from the said heating chamber through this small hole part from the said heating chamber The apparatus has a plurality of light sources arranged outside the small hole portion, and the light source is disposed so as to eliminate a shadow in a predetermined range in the heating chamber regardless of the size and pitch of the small holes in the small hole portion. In addition, the sheet attached to the small hole portion continuously changes from transparent to opaque from the back of the heating chamber toward the front, and the arrangement of the light source is perpendicular to the direction in which the sheet changes from transparent to opaque. Arranged in a row, the shadow of a specific place is eliminated, the brightness is uniform, and the area for suppressing the glare of the user is clarified .

As a result, the opaque area that reduces glare on the user's light source can be reduced, and as a result, the transparent area of the sheet 9 that illuminates the heating chamber 2 is expanded, so that the brightness in the heating chamber 2 can be maintained .

  Embodiments of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
In FIG. 1, reference numeral 1 denotes a heating apparatus main body, which is provided with a heating chamber 2 for heating an object to be heated by a heater or heating means (not shown) such as high frequency or steam. Reference numeral 3 denotes a door which is provided at the front opening of the heating chamber 2 so as to be freely opened and closed. A handle 4 is provided at the center upper portion of the door 3 so that it can be used when the user opens and closes it. Reference numeral 4 denotes an electrical equipment section that houses the heating means, and is provided at an appropriate position of the heating apparatus body 1. Reference numeral 5 denotes an operation unit provided above the door 3 of the heating apparatus main body 1, and operates the heating means and the like with the electrical unit 4. The wall surface of the heating chamber 2 is provided with a small hole portion 6 in which a plurality of small holes are formed as a lighting portion for illuminating an object to be heated on the bottom surface of the heating chamber 2. A unit 7 (not shown) is provided.

  FIG. 2 is a plan view of the heating chamber 2, showing the relationship between the small hole portion 6 for lighting on the wall surface, the light source unit 7, and the hole 8 on the door screen, from the user side (that is, from the heating chamber 2 in the operating state). By sticking an opaque sheet 9 to a specific area of the small hole so that light does not leak to the outer surface side through the door 3, the portion where the sheet 9 is not pasted can be bright and the pasted portion can be made dazzling. .

  In the case of the positional relationship of FIG. 2, the light from the light source directly leaks outside in the area A, but in the area B, the light depends on the relationship between the material thickness of the door screen, the light angle, and the hole diameter. Is not leaked, just by sticking the opaque sheet 9 to the lighting holes 6 for three rows from the front side of the heating chamber 2, the light is weakened and the light from the light source does not enter the user directly. Most are brightly illuminated through a transparent sheet.

  Furthermore, the sheet pasted in the small hole portion 6 is a sheet that continuously changes from transparent to opaque from the back of the heating chamber 2 toward the front, so that the conventional dark area at the back of the heating chamber 2 has the transparency of the sheet. Even if the amount of light from the light source is reduced due to the low transparency of the sheet on the front side, it is compensated by outside light from the outside of the door 3, so that the brightness of the bottom surface of the heating chamber 2 is uniform. There is an effect.

  In addition, a plurality of light sources on the light source unit 7 are arranged in a row at right angles to the direction in which the sheet becomes transparent to opaque (in the above, from the back to the front of the heating chamber 2). An opaque area that reduces glare on the light source of the person can be reduced, and as a result, the transparent area of the sheet 9 that illuminates the heating chamber 2 is widened, so that the brightness in the heating chamber 2 can be maintained.

  As is apparent from the above configuration, in this cooking device, even if the user looks into the heating chamber during heating, there is a sheet that prevents glare and can be operated without user discomfort.

  In these embodiments, it goes without saying that synergistic effects can be obtained by combining the functions.

  The cooking device of the present invention does not irradiate the light source as it is outside the heating chamber while illuminating the heating chamber, so that the door is closed during use and the cabin such as the heating chamber is illuminated, a microwave oven or an electric oven Can be used for applications such as reach-in showcases.
