Description

  The present invention relates to a heating cooker.

  A conventional heating cooker is known that includes an operation switch and an electrostatic operation switch that displays an operation state by emitting light only during use (see, for example, Patent Document 1).

  FIG. 7 shows a conventional cooking device described in Patent Document 1. As shown in FIG. The main body 1, the left heating unit 2 </ b> A, the right heating unit 2 </ b> B, and the post-heating unit 2 </ b> C for heating the object to be heated are arranged in the main unit 1, and the operation switch 3 and the current operation status display 4 are displayed to the user of the top plate 5. A partition frame that divides the light emitter and the minimum display section is provided below the top plate 5 and is provided at the near end 6 so that light is emitted and light is displayed on the top plate.

  With the above configuration, since the operation switch 3 and the current operation status display 4 are located at the end 6 close to the user, it is not necessary to look into the upper body without bending it, and the light is displayed only during use. It is easy to operate because it gives the user visibility.

  Also, in recent years, the top plate used in the cooking device is clean and has a top plate with a design that can make the top plate a single color and make it appear large and clear, because it is preferred to have a spacious and uniform appearance. A cooker is desired.

  In order to display the operation switch and the operation status with light emission and make the desired top plate with the above configuration, it is difficult to transmit visible light from the outside, and only light emission of a specific wavelength from the inside is visually recognized. This is possible with dark colors such as black.

  In other words, although it seems that there is nothing at first glance, it is possible to make a letter or the like emit light only when it is used. On the other hand, it is difficult to transmit only specific light in white and metallic tones.

  For this reason, a device has been devised to make it appear that nothing is displayed on the top plate while performing letter-like printing on the top plate (see, for example, Patent Document 2 and Patent Document 3).

  FIG. 8 is a cross-sectional view of a conventional cooking device described in Patent Document 2. As shown in FIG. A light-transmitting thin film 9 having a characteristic of transmitting a specific wavelength of emitted light more than other visible light is formed on the back surface of the top plate 5, a transmission opening 10 is provided, and the translucent film 11 is provided in the transmission opening 10. Is deposited.

  With the above configuration, the translucent film 11 shows the entire top plate 5 in substantially the same color tone and prevents the light-transmitting thin film 9 from being seen through from above the top plate 5. There is known a method of making it appear as if there is no light emission display only at the time of use.

  FIG. 9 is a cross-sectional view of the top plate of the heating cooker described in Patent Document 3. On the back surface of the top plate 5, the pearl tone layer 12 that expresses the pearl color tone, the coating layer 13 that stabilizes the color expression of the pearl tone layer 12, and the light shielding portion that expresses the light emission display 14, a transmissive opening 10 not covered by the light-shielding part 14, and a transparent resin layer 15 covering the transmissive opening 10 are formed by printing, and a light emitting body 7 is arranged below the top plate 5 to emit light. It is said.

  With the above configuration, the transparent resin layer 15 can be seen to have nothing at first glance, and a character or a pattern can be displayed by light emission only when in use.

  However, in the above-described conventional configuration, the top plate is directly cut out, and if the partition that surrounds each light emitter is not in direct contact with or in close proximity to the top plate, the light from the adjacent light emitter There is a problem in that light leaks and light is displayed in a non-light portion display that does not emit light.

  At this time, when the partition portion is brought into contact with or close to the top plate, a stress absorbing portion must be provided somewhere in view of the cracking of the top plate glass when the product is dropped.

  It has springiness from the main body side, and the light emitter and partitioning part may be biased to the top plate to absorb the stress by the springy part, but when incorporating the top plate into the main body, There is a high possibility that the printed display and the partition frame will not be aligned with the original position.

  In addition, by fixing the light emitter and the partition to the top plate side, the above-mentioned deviation can be improved. However, when the top plate and the main body are removed during service maintenance, the light emitter contacts the top plate side. As a result, the entire heating cooker could not be seen at a glance, which was troublesome twice, and had the problem of poor serviceability and repairability.

  The present invention solves the above-mentioned conventional problems, and in order to make the cooking surface visually clear and large and have a sense of unity, a single color, particularly light tones that are difficult to visually recognize the luminescent display, are provided.

With the above configuration, because the upper partition frame is in contact with or in close proximity to the top plate, light leaks from the gap between the top plate and the upper partition frame, and the adjacent unlit display portion that displays the light emission It is possible to prevent light emission from entering. Moreover, the location which absorbs the stress which propagates when a top plate is assembled | attached and a product falls can be provided by the fitting part of an upper partition frame and a lower partition frame. Furthermore, when the top plate and the main body are removed during service maintenance, etc., only the upper partition frame is attached to the top plate side, and other parts necessary for other cooking devices are fixed to the main body side. Can be configured.

  The heating cooker according to the present invention has an adjacent non-lighting display portion in which the upper partition frame is in contact with or in close proximity to the top plate and the light leaks and emits light with respect to the one having a display on the top plate side. In order to prevent light from being incident on the top plate, even if the top plate has a uniform color at first glance, it should be displayed only during use so that it is easy to use and inform the user. Can do. In addition, by providing a stress absorption location by the fitting part of the upper partition frame and the lower partition frame, there is no need to worry about breaking the glass of the top plate when the top plate is assembled into the main body or when the product falls. When the plate is assembled, there is no worry that the display on the top plate side and the light emitter will be misaligned. Furthermore, because only the upper partition frame is fixed to the top plate, the others are mounted on the main body side, so when removing the top plate and the main body during service maintenance etc., the main body of the heating cooker at a glance The inside can be confirmed, and a configuration with high maintenance efficiency can be obtained.

(Embodiment 1)
FIG. 1 is an overall configuration diagram of a heating cooker according to the first embodiment of the present invention.

  The main body 1 bends metal into a box shape, has an upper opening, a top plate 5 having a plurality of printing layers arranged to cover the upper opening of the main body 1, and a top plate 5 for installing the top plate 5 on the main body 1 It is composed of a metal frame 21 for supporting and connecting the top plate 5.

  In the main body 1, a left heating unit 2A, a right heating unit 2B, and a post heating unit 2C for heating an object to be heated are respectively incorporated. FIG. 2 is a cross-sectional view of the light emitting display portion of the heating cooker according to the first embodiment of the present invention.

  In FIG. 2, a light emitter 7 disposed on the lower side of the top plate 5 for displaying the operation switch 3 (FIG. 1) and the operation status display 4 (FIG. 1) fixed to the main body 1 on the top plate 5 is displayed. A plurality of light emitting substrates 22 (FIG. 2) are provided.

  A lower partition frame 24 having a lower partition portion 23 for partitioning light emitted from the light emitter 7 is fixed to the light emitting substrate 22.

  On the other hand, on the top plate 5, as described above, at least one layer of the frame 21 that supports the top plate 5 and the printed layer printed on the back surface of the top plate is removed to form a light-emitting display character or design. A light-shielding portion 14 is provided, and has an upper partition portion 25 that partitions light from the light emitter 7 so as to abut against or be close to the back surface of the top plate 5 and allows light from each light emitter to enter from below. An upper partition frame 26 provided with holes 27 is fixed to the frame 21.

  At this time, fixing may be performed by making a hole in the frame and using a screw or the like. The upper partition frame 26 is under the light shielding portion 14 printed on the top plate 5, and the through hole 27 provided in the upper partition frame 26 does not cover the characters or symbols A, B, and C formed by the light shielding portion 14. Formed and fixed.

  Further, the top plate 5 is configured to be pressed and connected to the main body 1 from above to be incorporated. For example, when there is no upper partition frame 26 and the lower partition frame 24 is in contact with the top plate 5 to prevent light leakage, the top partition 5 is pressed downward from above when the top plate 5 is assembled. There is a possibility that stress is applied between the top plate 5 and the top plate 5, and the top plate 5 is broken or the lower partition frame 24 is damaged.

  There is a similar risk when the product falls. Although the lower partition frame 24 is spring-like and urged from below to the top plate 5 to provide a stress absorbing portion at the spring-like portion, cracking of the top plate 5 and damage to the lower partition frame 24 can be avoided. When the top plate 5 is assembled into the main body 1, it is difficult to reliably arrange the lower partition 23 under the light shielding portion 14 forming the display on the top plate 5 side, and the light emission display is shifted. There is a high possibility that it will end.

  On the other hand, by adopting the above configuration, the stress propagated when the top plate 5 is connected and incorporated into the main body 1 and when the product is dropped is absorbed by the fitting portion between the upper partition frame 26 and the lower partition frame 24 and absorbed. By providing the location, there is no fear of damaging the top plate 5 or the lower partition frame 24. When the top plate 5 is assembled, the upper partition frame 26 already surrounds the display on the top plate side and partitions the light emission. No worries about shifting.

  Furthermore, if the light emitting substrate 22 is configured on the top plate 5 side, the top plate 5 must be removed, and the light emitting substrate 22 attached to the top plate 5 side must be disassembled and removed. Although it cannot be confirmed, with the above configuration, when the top plate 5 is removed from the main body 1 during service maintenance or the like, only the upper partition frame 26 and the frame 21 are located on the top plate 5 side. 5 is a light-emitting body 7 that is attached to the side 5 and emits and displays the other necessary components for the cooking device, such as the left heating unit 2A, the right heating unit 2B, the post-heating unit 2C, the operation switch 3, and the operation status display 4. And the light emission board | substrate 22 is mounted in the main body 1 side, and can confirm the whole inside of a heating-cooker main body at a glance. Therefore, it can be set as the structure where the efficiency of service maintenance is good.

  Furthermore, the lower partition frame 24 is provided with an inclination that widens the lower partition portion 23 upward, and the upper partition frame 26 and the lower partition frame 24 are fitted to each other, whereby incorporation can be smoothly guided. Therefore, the top plate can be easily incorporated into the main body.

  Further, when the upper partition frame 26 and the lower partition frame 24 are formed of a material and color that easily reflect light, the light from the light emitter 7 irradiated from below can be given directivity, and one light emitter It is possible to make it possible to emit a wide display.
