The present invention relates to a cooking apparatus capable of cooking food using a heating element such as a heater.

In general, various cooking appliances include microwave ovens, ovens, and cooktops. The microwave oven heats the food by irradiating the microwave generated by the magnetron in the sealed cooking chamber to vibrate the water molecules of the food stored in the cooking chamber, and the oven is stored in the cooking chamber by heating the sealed cooking chamber using a heater. The cooked food. The cooktop generally heats the food contained in the bowl by heating the bowl placed on its upper surface using a burner.

Among the above cooking devices, the cooktop can cook various kinds of foods, and thus, the cooktop is generally built-in to a kitchen counter and used as a main cooking device. The microwave oven and the oven are installed in a cupboard or a kitchen counter. It is used as an auxiliary cooking device.

As a heat source of the cooktop, a burner using gas or electricity is generally used. In the case of a gas cooktop using gas as a heat source, since heat loss caused by a flame is large, thermal efficiency decreases. Therefore, the use of an electric cooktop that adopts a radiant heater operated by electricity provides a higher thermal efficiency than a gas cooktop. It is increasing.

The electric cooktop generally includes a glass plate on which a bowl is placed, a heater operated by electricity disposed below the glass plate, and a reflecting plate disposed to surround the heater to reflect the heat of the heater. do.

In the case of using a coil heater as the heater, its output and efficiency are relatively low. To improve this, a lamp heater such as a high output halogen heater may be used as the heater. Since a lamp heater such as the halogen heater has a high output, one can be arranged in a straight line or bent on the reflector to obtain a sufficient output for cooking.

When the heater generates heat, the lamp heater emits light together with heat, and the emitted light is transmitted out of the cooktop through the glass plate. Therefore, when the heater generates heat, the user can see the appearance of the heater, but the part where the heater is located is bright but the other part is dark, so that the user may be mistaken that the glass plate is not evenly heated. That is, even if the glass plate is sufficiently heated by the heat emitted from the heater, the user may feel that the output of the heater is insufficient due to the light emitted from the heater.

SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and an object thereof is to improve the structure of a burner mounted to a cooking appliance so that the glass plate appears to be heated evenly and sufficiently by the heater during operation of the cooking appliance. .

In one embodiment of the present invention for achieving the above object, a glass plate; A heater disposed below the glass plate; And disposed below the glass plate to surround the heater, provides a cooking device comprising a reflecting plate having a curved surface reflecting the light of the heater in various directions so that the image of the heater appears to the consumer several.

DETAILED DESCRIPTION Hereinafter, embodiments of the present invention in which the above object can be specifically realized are described with reference to the accompanying drawings. In describing the embodiments, the same names and symbols are used for the same components, and additional description thereof will be omitted below.

1 is a perspective view showing an embodiment of a cooking appliance according to the present invention. The cooking apparatus according to the present invention includes a cooktop C provided with a plurality of burners 100. In addition, the cooking appliance may further include an oven (O) opened and closed by a door (d) disposed below the cooktop (C). The oven (O) may be provided with a magnetron for irradiating microwaves into the cooking chamber of the oven (O) as well as a heater operated by electricity. The cooking appliance according to the present invention may be provided built-in to the kitchen counter for the convenience of the user. For reference, reference numeral P of FIG. 1 is a control panel including a control unit for controlling a cooking appliance.

The glass plate 110 is provided on the upper surface of the cooktop (C). The glass plate 110 may be made of ceramic, and may include an indication such as a leader line for informing a user to put food to be cooked at an accurate position, and to have transparency so that the user may see the bottom side. Can be formed.

A plurality of burners 100 are provided below the glass plate 110. The burner 100 may be formed to have different sizes to cook food using various sized bowls, as shown in FIG. May be Although the size and shape of the burner 100 may be provided differently, the structure is substantially the same.

2 and 3, the burner according to the present invention is shown well, hereinafter, the structure of the burner according to the present invention will be described in more detail with reference to these drawings. For reference, FIG. 2 is a perspective view showing an embodiment of a burner provided in the cooking apparatus of FIG. 1, and FIG. 3 is an exploded perspective view of the burner of FIG. 2.

As shown in FIGS. 2 and 3, the burner 100 is provided with a heater 120 that generates heat by electricity. The heater 120 may include, for example, a carbon heater of a lamp type. In more detail, the carbon heater has a structure in which a resistance heating element made of carbon is positioned at the center of the hermetically sealed quartz tube, and both ends of the carbon heater are electrically connected to the external electrode by a connection part such as a metal piece. The inside of the quartz tube is vacuum or filled with an inert gas to prevent the oxidation of the resistance heating element made of carbon at high temperature. The heat generating part of the heater 120 configured as described above, that is, the quartz tube part for sealing the resistance heating element is bent in a circular or horseshoe shape (Ω) and disposed below the glass plate 110.

A reflector 200 is disposed below the heater 120 to reflect light and heat generated from the heater 120 toward the glass plate 110. The reflector 200 may be formed of, for example, aluminum and may be specially processed to provide high heat resistance and heat reflection performance.

The heater supporter 150 is provided between the heater 120 and the reflector 200. The heater supporter 150 prevents the heating portion of the heater 120 from sagging and maintains the position of the heater 120 by supporting the heating portion of the heater 120.

A base plate 140 may be provided below the reflector 200 to surround the bottom and side surfaces of the reflector 200 as shown in FIGS. 2 and 3. The base plate 140 also serves to prevent heat from being transferred from the reflector 200 along with the case of the burner 100 to other parts of the cooking apparatus.

Both ends of the heater 120 may be exposed to the outside after passing through the reflector 200 and the base plate 140 as shown in FIGS. 2 and 3 so as to be connected to an external electrical terminal. . In addition, a thermostat 160 for preventing overheating of the heater 120 may be attached to a side of the base plate 140. The operation bar 161 of the thermostat 160 may be installed to penetrate the reflecting plate 200 and then positioned inside the reflecting plate 200 as shown in FIG. 2. Therefore, when the heater 120 is overheated, the operation bar 161 operates the thermostat 160, whereby the supply of electricity to the heater 120 is stopped, thereby preventing the heater 120 from being damaged due to overheating. Can be effectively prevented.

When electricity is supplied to the heater 120, light and heat emitted from the heater 120 are reflected by the reflector 200 and transferred to the glass plate 110. As a result, the glass plate 110 is heated, and the dish and food placed on the glass plate 110 are heated and cooked.

In this case, since the glass plate 110 has a degree of transparency, the user can see the light reflected by the reflector 200 after being emitted from the heater 120. Since the glass plate 110 is not heated enough to be noticed by the user even though the glass plate 110 is sufficiently heated by the heater 120, the user views the image of the heater 120 viewed through the glass plate 110 and the heater. It is possible to gauge whether the 120 is working and how much the glass plate 110 is being heated.

Therefore, if the images of the heaters are shown to the user through the glass plate 110, and the images of the heaters shown occupy a large area of the glass plate 110, the user may use several heaters to heat the heater 120. The output of is sufficient and the glass plate 110 also feels heated evenly. In order to obtain such an effect, the reflector 200 according to the present invention has an improved structure such that even though one heater 120 is mounted on the burner 100, the image of the heater 120 appears to be different to the consumer. . Hereinafter, a unique structure of the reflector 200 according to the present invention will be described in more detail.

The inventors use the reflector as shown in FIGS. 4 to 7 to obtain the shape of the reflector 200 configured to show several images on the glass plate 110 of the burner 100 equipped with one heater 120. Experiments were made with various shapes, and as a result, a shape as shown in FIG. 7 was obtained. Hereinafter, with reference to these drawings will be described in more detail.

For reference, Figure 4 is a cross-sectional view and a plan view showing the appearance of the heater is reflected on the glass plate of the burner when the reflecting plate is flat; 5 is a cross-sectional view and a plan view showing a state in which the heater is reflected on the glass plate of the burner when the dome is provided in the center of the reflector; 6 is a cross-sectional view and a plan view showing a state in which the heater is illuminated on the glass plate of the burner when the dome is provided at the center of the reflector and the bump is formed below the heater; 7 is a sectional view taken along line II ′ of the burner of FIG. 2 in accordance with the present invention; And Figure 8 is a plan view showing the appearance of the heater is reflected on the glass plate of the burner when the reflector according to the invention is provided.

First, as in the burner 100a illustrated in FIG. 4, when the reflecting plate 200a has sidewalls perpendicular to the flat bottom surface, the glass plate 110 is attached to the glass plate 110 by the heater 120. One phase, ie, the first phase 111a, formed by diverging directly toward the top appears. Thus, the user can substantially see only one image.

Since the reflector 200a of the burner 100a of FIG. 4 does not substantially have an inflection surface capable of reflecting light emitted from the heater 120 in various directions, the heater 120 actually emits light. ) Was judged to be visible to the user. Accordingly, the inventors have changed the structure of the reflector so that the reflector has an inflection surface that reflects light of the heater 120 in various directions.

The inventors placed a convex dome 210b at the center of the bottom 205 of the reflector 200b of the burner 100b, and the dome 210b at the bottom of the dome 210b, as shown above in FIG. The first strip 212b protrudingly protruded along the circumference thereof, and the side wall 220b of the reflecting plate 200b is formed to be inclined to approach inwardly downward, and then the side wall 220b and the bottom ( The point where 205 meets is rounded. In addition, the inventors arranged the heater 120 to surround the dome 210b, and the first strip 212b is disposed to be located inside the heater 120.

After changing the structure of the reflector 200b as described above and observing the image of the heater reflected on the glass plate 110 after turning on the heater 120, as shown in the lower part of FIG. Four were found.

Among the phases of the four heaters 120 shown in FIG. 5, the brightest first phase 111b appears to be a phase formed by light emitted directly from the heater 120, and is formed inside the first phase 111b. The second image 112b is seen as an image formed by the light reflected by the first band 212b. In addition, the fourth phase 114b formed inside the second phase 112b is viewed as a phase formed by the side surface of the dome 210b. Since the upper end of the dome 210b rises higher than the upper end of the heater 120 in the inner center of the heater 120, the fourth phase 114b appears intact. Finally, the sixth image 116b formed at the outer side of the first image 111b is viewed as the image formed by the side surface 220b of the reflector plate 200b.

As described above, a plurality of inflection surfaces, for example, a dome 210b, a first strip 212b, and a side surface 220b are formed on the reflecting plate 200b, so that the light reflected by each inflection surface is different. Since three images are formed, the user can view several images. In order to obtain more heater phases, the inventors modified the structure of the reflector 200c mounted to the burner 100c as shown in FIG.

As shown above in FIG. 6, the inventors placed a convexly raised dome 210c in the center of the bottom of the reflector plate 200c, and formed a first strip 212c along the lower circumference of the dome 210c, and the side surface thereof. 220c was formed to be inclined. Here, the dome 210c of FIG. 6 has an upper end more rounded than the upper end of the dome 210b of FIG. 5, and is disposed at substantially the same height as the upper end of the heater 120. Unlike that of FIG. 5 which was substantially flat, it was formed convex to have an arc shape. The first strip 212c was also formed convexly to have an arc cross section.

In addition, the inventors further placed the raised portions 230 protruding from the bottom of the heater 120. The ridge 230 protrudes toward the heater 120 from the bottom of the reflector 200c positioned between the dome 210c and the side surface 220c. When the ridge 230 does not have a heater 120, when viewed from above, the ridge 230 surrounds the dome 210c and is hidden by the heater 120 when the heater 120 is installed. Both sides of the raised portion 230 formed as described above is formed concave as shown in FIG.

When the structure of the reflector 200c was changed and the heater 120 was turned on as described above, five heaters were observed as shown in the lower part of FIG. 6. The first phase 111c, the second phase 112c, the fourth phase 114c, and the sixth phase 116c appear to be formed by the same principle as described with reference to FIG. 5. In addition to these heaters, as a result of using the reflecting plate 200c of FIG. 6, the fifth phase 115c located inside the fourth phase 114c was further observed. The fifth phase 115c may be further formed by smoothly rounding the upper end of the dome 210c and placing the height at substantially the same height as the upper end of the heater 120.

As shown in the lower part of FIG. 6, an image of the heater 120 is not further formed by the ridge 230. This is because the ridge 230 is disposed below the heater 120 vertically. Instead of forming the additional heater image, the ridge 230 reflects the light emitted vertically downward from the heater 120 in another direction, thereby preventing the reflected light from heating the lower surface of the heater 120 again. prevent. As a result, overheating of the heater 120 is prevented and the efficiency of the burner is increased. In addition, an effect of making the boundary between the second phase 112c and the sixth phase 116c disposed adjacent to the first phase 111c more prominent can be obtained.

Through the process of changing the structure such that the reflector has an inflection surface as described above, the inventors can obtain the shape of the reflector 200 as shown in FIG. Hereinafter, the structure of the reflector 200 shown in FIG. 7 will be described in more detail.

The dome 210 is disposed at the center of the bottom 205 of the reflector 200. The dome 210 is located in the middle portion of the heater 120 that is bent roundly when viewed from above. A plurality of bands protrude convexly along the circumference of the dome 210 on the side of the dome 210. The bands have an arc-shaped cross section, for example, and a plurality of bands are disposed from the bottom to the top of the dome 210.

In more detail, the first strip 212 is disposed along the lower circumference of the dome 210, the second strip 213 is disposed above the first strip 212, and the third strip 214. ) Is disposed between the second strip 213 and the top 215 of the dome 210. The upper end 215 of the dome 210 is smooth and rounded, and is disposed between the upper end and the lower end of the heater 120. The upper end 215 of the dome 210 may be disposed higher than the installation height H2 of the heater 120, for example. An inflection line forming a boundary is formed between the bands and between the third band 214 and the upper end 215 of the dome 210.

Here, the heater 120 and the reflector 200, the diameter (D2) of the heater 120 / the diameter (D1) of the reflector 200 corresponds to approximately 0.5 ~ 0.8, the inside of the reflector 200 The installation height H2 of the heater 120 / the height H1 of the reflecting plate 200 is installed to correspond to approximately 0.4 ~ 0.8. In this case, the height of the dome 210 may be formed such that the height H3 of the dome 210 / the height of the reflecting plate H1 correspond to approximately 0.5 to 0.9. In addition, the size of the dome 210, the diameter (D3) of the dome 210 / diameter (D2) of the heater 120 may be formed to correspond to approximately 0.5 ~ 0.9. Here, the diameter D3 of the dome 210 may be measured as a value excluding the first band 212.

On the other hand, the side surface 220 of the reflecting plate 200 surrounding the heater 120 is formed to be inclined inward toward the bottom. In addition, a convex surface is formed on the side surface 220 of the reflecting plate 200, which has an arc-shaped cross section and protrudes convexly toward the heater side. Although the ridge 230 is not shown in FIG. 7, the ridge 230 may be provided on the bottom 205 of the reflector 200 as shown in FIG. 6.

As a result of forming the structure of the reflector 200 and turning on the heater 120 as shown in FIG. 7, six heaters were observed as shown in the lower part of FIG. 8. The first phase 111 appears to be formed by light emitted directly from the heater 120, and the second phase 112 positioned inside the first phase 111 is formed by the first band 212. As shown, the third phase 113 located inside the second phase 112 may be formed by the second band 213. In addition, the fourth phase 114 located inside the third phase 113 may be formed by the third strip 214, and the fifth phase 115 located inside the fourth phase 114 may be formed in the fourth phase 114. It appears to be formed by the top 215 of the dome 210, and the sixth phase 116 located outside the first phase 111 appears to be formed by the side surface 220.

As described above, a plurality of inflection surfaces provided on the reflector 200, that is, a dome 210 disposed at the center of the reflector 200 and a plurality of bands 212, 213, and 214 arranged around the dome 210. ), And the upper surface 215 of the dome 210 and the side surface 220 of the inclined and convex reflective plate 200, the glass plate 110 has a plurality of heater images 111, 112, 113, 114, 115, 116) will appear.

Thus, the user may feel that a plurality of heaters are mounted even though one heater 120 is mounted on the burner 100. In addition, the user may feel that the output of the burner 100 is high so that the glass plate 110 is sufficiently and evenly heated.

Although several embodiments have been described above, it will be apparent to those skilled in the art that the present invention may be embodied in many other forms without departing from the spirit and scope thereof. Accordingly, the described embodiments are to be considered as illustrative and not restrictive, and all embodiments within the scope of the appended claims and their equivalents are included within the scope of the present invention.

According to the invention, even if one heater is mounted on the burner, the user can see several heater phases when the burner is operated. Thus, the user may feel as if the heaters are mounted so that the output of the burner is sufficient, and the glass plate is sufficiently and evenly heated. Thereby, there is an effect that can increase customer satisfaction.

In addition, according to the present invention, since a beautiful concentric heater image is seen to the user during the operation of the burner, the aesthetics of the product is further improved.
