JPH0464823A - Residual heat display device for cooker - Google Patents

Abstract

PURPOSE:To prevent light emitted from a light emitting part from being concentratedly collided with a heat resisting plate and to make a display mark sharp and easy to watch by a method wherein a translucent plate is located between the heat resisting plate and a plate on which a mark to attract attention is drawn. CONSTITUTION:An attention attracting mark is drawn on the upper surfaces of clear glass plates 9 and 9A. Two panes of translucent glass 11 and 11A are disposed right above the clear glass plates 9 and 9A. Since light emitted from light emitting parts 6 and 6A located right below the clear glass plates 9 and 9A is prevented from being concentratedly collided with the uneven surface of the under surface of a heat resisting glass 3, this constitution prevents production of a shape and enables execution of sharp and distinct display on display zones 8 and 8A.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a residual heat display device for a cooking appliance.

2. Description of the Related Art A conventional residual heat display device for this type of cooking appliance is shown in FIG. In FIG. 6, a heat-resistant glass 3 is attached to the upper opening 2 of the appliance body 1, and a plurality of stove parts 5 each having a heat source 4 such as a halogen lamp are provided inside the appliance body 1. Inside the appliance body 1, residual heat display sections 7 each having a light emitting section 6 such as an LED lamp are provided in accordance with the number of stove sections 5. In the above configuration, the residual heat display section 7 operates depending on whether or not there is residual heat in the heat-resistant glass 3 after the stove section 5 is used. If there is residual heat, the LE provided in the residual heat display section 7
A light emitting unit 6 such as a D lamp is blinked to clearly indicate the display zone 8 provided on the heat-resistant glass 3. Now, if the power is turned on to the stove part 5 and the stove part 5A and cooking is in progress, and the left stove part 5 is turned off in order to stop using it, the heat-resistant glass 3 will be exposed immediately after use. I have a residual fever for a while. Therefore, the display zone 8 flashes. Similarly, when the power is turned off to stop using the right stove section 5A, the left stove section 5
The display zone 8A blinks for the same reason as in the case of . Furthermore, the display zone 8B of the central stove section 5B (not shown) also blinks.

Problems to be Solved by the Invention However, in such a configuration, the residual heat display section 7 and the display zones 8, 8A, and 8B are located at a distance from the positions of the stove sections 55A and 5B, and the display zones 8, 8A are smaller. and 8B are only illuminated in red by the light emitting parts 6.6A and 6B, and there is a problem that it is difficult to distinguish them unless they are checked carefully. As a result, there was a risk of inadvertently touching the heat-resistant glass 3 and getting burned.

By the way, in order to make the display zone easy to check, it is possible to increase the size of the display zone so that a mark such as a picture or text is clearly displayed in the display zone. In this case, not just a red lamp is clearly displayed in the display zones 8, 8A, and 8B, but a mark with pictures, letters, etc. is displayed through the heat-resistant glass 3, so the display zone 8. The ease with which 8A and 8B can be confirmed is also related to the light transmittance of the heat-resistant glass 3.

The object of the present invention is to clearly display a mark calling for attention in an extremely easy-to-understand red color in the display zone only when there is residual heat.

Means for Solving the Problems In order to solve the above problems, the residual heat display device for a cooker of the present invention includes a plate with a mark drawn to call attention to the lower part of the heat-resistant plate on which the object to be heated is placed. , a light emitting part that projects light from the lower part of the plate, and a semi-transparent plate between the heat resistant plate and the plate.

According to the present invention, with the above-described configuration, when there is residual heat on the heat-resistant plate, a mark drawn on the plate to draw attention is projected by the light emitting unit. The projected mark then passes through the heat-resistant plate via the semi-transparent plate. This transmitted mark is visible to the human eye, allowing the user to recognize the status of the cooker.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5 of the drawings. Note that the same members as in FIG. 6 are given the same reference numerals.

A heat-resistant glass 3 is attached to the upper opening 2 of the instrument body 1, and a heat source 4, such as a halogen lamp, is installed inside the instrument body 1. A stove part 5 having a heat source 4A and a heat source 4B (not shown). The stove part 5A and the stove part 5B (not shown) are shown in FIG.
), there are three of them. Hereinafter, a case where there are two pieces connected to the stove section 5 and the stove section 5 will be described. The residual heat display section 7 and the residual heat display section 7A provided near the stove section 5 include, in order from the bottom, a light emitting section 6 such as a lamp, a light emitting section 6A,
Plate 9 and Plate 9A have a mark drawn to warn people not to touch the cooker with their hands while using it.
, and three lengths of heat-resistant glass are provided, which are attached to the lamp house 10 and the lamp house IOA, respectively. Three residual heat display sections are provided depending on the number of stove sections, and a mark consisting of a handprint and an "X" is drawn on the plate 9.9A as shown in FIG.

In other words, on the top of 9.9A (play), there is a handprint drawn in white on a black background, and overlaid on top of this is a pattern with a thick line marked with an x in white. A translucent glass body 11 and a translucent glass body 11A are provided directly above the plate 9.9A and directly below the heat-resistant glass 3. Moreover, the display zone 8 and the display zone 8A of the heat-resistant glass 3 are made large in size.

In the above configuration, the residual heat display parts 7, 7 according to the usage state
The operation of the display contents of A will be explained.

(1) State where there is no residual heat The temperature of the stove section 5 is low, the light emitting section 6 of the residual heat display section 7 is in the off state, and a warning drawn on the plate 9 is displayed in the display zone 8 of the heat-resistant glass 3. The mark to be used is not clearly indicated. That is, as shown in FIG. 4(a).

(2) State where there is residual heat The heat source 4, such as a halogen lamp, installed inside the container opening 5,
When a predetermined applied voltage is applied, the temperature becomes high. The heat emitted by the heat source 4 is transmitted through the heat-resistant glass 3 to an object to be heated (such as a pot) placed on the heat-resistant glass 3 (not shown), thereby heating the object. While the object to be heated is being heated, the light emitting section 6 of the residual heat display section 7 is in an off state. This is heating zone 1
Since the object to be heated is placed on top of 2, the high temperature heating zone 1
This is because there is no fear of touching 2. After that, when cooking is finished and the power to the heat source 4 of the stove section 5 is turned off, the light emitting section 6 of the residual heat display section 7 is activated for a while (for a while) as the stove section 5 is in a high temperature state. As a result, a state in which the mark on the plate 9 is blinking in red is clearly shown in the display zone 8, as shown in FIG. 4(b).

In either case, the above operation is controlled by a temperature sensor (not shown) provided in the condenser mouth part 5, and the residual heat display part 7 blinks when the temperature exceeds a predetermined temperature. The light is turned off when the temperature is below.

The operation is as described above, but the handprint and the X mark to call attention are commonly introduced in printed materials. However, if this mark is to be displayed on the heat-resistant glass surface of the cooker, it is necessary to devise ways to overcome the following problems.

(1) One surface of the heat-resistant glass 3 is flat, but the other surface has irregularities with small diameters (Fig. 5 (b)
), shown in (C)). This is to clearly show the front and back sides of the glass and to diffuse light emitted from a halogen lamp or the like provided at the bottom. In the case of this type of heat-resistant glass 3, if light is applied intensively, the light will hit the uneven portions and create shadows. Therefore, the mark becomes difficult to see.

(2) Stove section 5°5A located at the bottom of heat-resistant glass 3
The halogen lamp used as the 4.4A heat source has a color temperature of up to 3000'K and a wavelength of just under 1 μm. For this reason, the heat-resistant glass 3 is made so that the wavelength peaks at a little less than 1 μm in order to improve transmission.

Therefore, when the temperature is low, it becomes difficult to penetrate. In addition, halogen lamps are dazzling when viewed directly with the human eye, and heat-resistant glass 3.
is colored to reduce the degree of negative impact on the eyes.

In view of the above, when marking a mark in red using a halogen lamp or the like, it is necessary to devise means for displaying the mark in order to make it easier to understand and to draw more attention to the mark. Below, the mark display means are shown in Figures 3 (a) and (b).
) and (c).

(]) In the case of Fig. 3(a), the transparent glass plate 9
゜A caution mark is drawn on the top surface of 9A.As shown in Figure 2, the entire top surface of plates 9 and 9A is black, and the handprint is drawn in white with a line inside.
The X mark is also outlined with a line.

Then, a translucent glass (ground glass type) 11. IIA has been set up. With this configuration, a transparent glass plate 9.9A
Since the light emitted from the light emitting parts 6, 6A located directly under the heat-resistant glass 3 does not intensively hit the uneven part of the lower surface of the heat-resistant glass 3, it can be clearly displayed in the display zone 8.8A without creating a shadow. .

(2) In the case of FIG. 3 [present], the mark calling for attention is a plate 9 punched out with a press or the like.

Directly above this plate 9.9 is a translucent glass (ground glass type) 11. IIA has been set up. As a result, the same effect as in case (]) above can be obtained.

(3) In the case of Figure 3 (C), one side of the glass is made transparent, a warning mark is drawn on this transparent part, and the other side is made semi-transparent.) 9, 9A is formed. There is.

And just above this plate 9 is a translucent glass (ground glass type) 11. IIA has been set up. As a result, the same effect as in the case (1) above can be obtained.

As described above, according to the residual heat display device for a cooker according to an embodiment of the present invention, - the above-mentioned mark is not only displayed on the glass body, etc. Since the display means (]), (2), and (3) are clearly displayed, it is possible to call even more attention to the danger of burns, etc.

Effect of the invention As described above, according to the present invention, the following effects can be obtained.

(1) By providing a semi-transparent plate between the heat-resistant plate and the plate with a mark drawn to call attention to it, the light emitted from the light emitting part does not intensively hit the heat-resistant plate. Therefore, the displayed mark does not have uneven brightness or shadows, and the mark is clear and easy to see.

(2) When the temperature of the heat-resistant plate is high, a large flashing mark will be displayed on the heat-resistant plate to warn you not to touch it. Therefore, it is now possible to tell at a glance who is using the cooker and who is not, and it also prevents accidents such as accidentally touching the heat-resistant glass that previously occurred due to the difficult to understand display. By this,
It has improved safety against burns.
