I: Prior Art 3 Background Art In the past, generally, a top plate for a stove was formed of a pressed steel plate. In order to ensure the rigidity, the outer peripheral edge portion of the steel plate top plate or the opening edge portion of the opening for the burner is formed in a shape that is raised than other portions (for example, refer to Patent Document 1). As a result, the top plate cannot be flat, and a heavy feeling cannot be obtained, which gives the user a cheap feeling. Therefore, the applicant of the present invention first proposed a ceiling plate for a stove formed by a thick metal (for example, aluminum) flat plate through Japanese Patent Laid-Open Publication No. 2003-40523. Since the flat plate constituting the top plate itself is highly rigid, it is not necessary to form a raised portion for strengthening the rigidity on the top plate. Therefore, the top plate can be flat, and it has a visually heavy feeling and high-grade feeling. [Patent Document 1] Japanese Patent Laid-Open Publication No. 2002_257358 No. 20 [No. Minami] Disclosure of the Invention Problems to be Solved by the Invention However, in the above-mentioned flat plate top plate of the above-mentioned case, a text and a figure are added to the top plate. When the logo is composed of patterns, patterns, etc., the logo will only be recessed by embossing 1235809 'from the top, and the concave view. In addition, it is also possible to reduce the thickness of the thin printed logo, which makes it difficult to peel off during cleaning. To print the logo. However, in this way, it is easy to accumulate dirt and damage the outer film to stick to the top plate. However, if the situation of the film occurs and the damage is 5 10, it will be used for the burner installed on the stove body. Openings or universal openings with far surnames such as ,,,, and "shafts," so the know of the material is used as soup, and ten r η mouths-in ... _ Zhi, Luo to the top plate overflows all the openings into the furnace The body is made of a flat plate made of the above-mentioned case, and a ring-shaped gasket is installed at the edge portion of the opening σ, and a portion of the lining from the top plate = the raised lining constitutes an embankment portion that can surround the opening. It prevents the soup that overflows from the luo to the top plate from flowing into the stove body through the opening. However, this will increase the number of parts and increase the cost. Also, it is used for the burner for taking the burner into the stove body. The air is exhausted from the grill in a stove with a grill. Therefore, a vent connected to the body of the 15 stoves is provided at the rear of the top plate. In the flat top plate made of the foregoing case, ventilation is performed. It is formed in the back of the top plate with an opening, but at this time, it must be It is necessary to provide a shield member for preventing foreign matter from falling from the air vent on the top plate, so that the number of parts will increase and the cost will increase. In view of the above problems, the first problem of the present invention is to provide The mark raised upwards is affixed to the top plate by the engraved 20 mark method, and it is possible to prevent dirt from accumulating on the top plate of a flat-plate stove for marking. In addition, the second object of the present invention is to provide other components that can In the case of a component, a top plate for a flat-plate stove that prevents overflowing soup from flowing in from the opening, and a third object of the present invention is to provide a vent in the rear of the top plate and prevent foreign matter without using other components 1235809 The top plate for a flat-plate stove dropped from the ventilation σ. Means for solving the problem 5 10 According to the first feature of the present invention, in order to solve the above-mentioned problem, the top plate is made of metal that covers the stove body from above. The creator of the flat panel ^ can add a logo composed of text, graphics, patterns, etc. in a predetermined area on the top panel, and in the aforementioned shape of the top panel, under the aforementioned top panel_ The thickness is thinned by cutting ', and by pressing the pre-money field, the logo is embossed on the top plate. According to the second feature of the present invention, in order to solve the second problem, The stove top plate is formed by a metal flat plate covering the stove body from above, and has an opening. At the edge portion of the opening of the top plate, the thickness under the top plate is reduced by cutting, and The edge portion is pressed and the edge of the opening forms a cylindrical protrusion standing upright from the top plate surface. Furthermore, according to the third feature of the present invention, in order to solve the third problem, the top plate for a stove is made from above The metal flat plate covering the main body of the stove is formed. Further, at the middle portion other than the left and right ends of the rear side of the top plate, the thickness under the top plate is cut to be thinner, and the middle portion is pressed to protrude to the foregoing portion. The upper surface of the top plate is provided with an air vent which is covered by the middle portion of the 20 from above and communicates with the body of the stove. According to the present invention, the main portion of the top plate formed of the flat metal plate is thinned in any of the features, whereby the same pressing process as the sheet metal can be applied to the portion. In addition, since the thickness under the top plate is cut to make it thinner, the recesses caused by the thinning will only exist under the top plate and will not appear from the outside 1235809, so the appearance of the top plate can be maintained well. In addition, as in the above-mentioned first feature of the present invention, if the area to which the logo is attached is made thinner, press processing from the following molding or the like can be applied to the area, whereby the logo can be clearly engraved in a raised state. On the top plate. 5 This is different from the case where the logo is recessed to be engraved by being embossed from above. The logo does not accumulate dirt and is easy to clean. At the same time, it does not cause poor appearance due to film peeling when the film is pasted. Situation, and can improve commerciality. In addition, as in the second feature of the present invention, if the opening edge portion 10 of the top plate is made thin, a pressing process such as flange forming can be applied to the opening edge portion, whereby the edge of the opening can be easily formed from above the top plate. Tubular protrusions standing upright. Thereby, the cylindrical protrusion has a function of a bank portion surrounding the opening, and can prevent the overflowing soup from flowing into the opening without using other members such as a gasket, and can reduce the number of parts and the cost. 15 In addition, if the middle part of the rear part of the top plate is made thinner as described in the third feature of the present invention, press processing such as stretching processing may be applied to the middle part, thereby allowing the middle part to protrude to the top plate surface. A vent is secured below it, and the vent is covered from above by the middle section. Thereby, foreign matter can be prevented from falling out of the vent without using other components, and the number of parts can be reduced, and the cost can be reduced. I: Embodiment 3 Best Mode for Carrying Out the Invention An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a perspective view showing a stove having a top plate according to an embodiment of the present invention, Fig. 2 is a sectional view of a stove cut along line II-II of Fig. 1235809 j, and Fig. 3 is a top plate of an embodiment FIG. 4 is an enlarged cross-sectional view of the middle portion cut off along the line 1-IV in FIG. 3. Fig. 1 shows the 崁 5-in stove of the conditioning table 1 (refer to Fig. 2) placed in the system kitchen. This hob is a hob body 2 having a box transformer with an upper surface as an open surface as shown in FIG. An outer-curved flange 3 is formed on the upper edge of the stove main body 2. When the stove-main body 2 is placed in the stove opening la provided on the conditioning table 1, the outer-curved flange 3 is hung on the stove opening la An opening edge portion is provided, and the stove body 2 can be hung and held on the conditioning table 1. Furthermore, the cooker body 2 is covered from above by the top plate 4 over the outer curved flange 3. A gasket 3a is attached to an edge portion of the outer curved flange 3, and the outer curved flange 3 is attached to the console 1 through the gasket 3a. Three burners 5 as heat sources are arranged in the stove body 3 on the left and right and behind the middle portion. The left and right burners 5 are composed of a mother and child burner including a mother burner & and a burner 5b on the inside thereof. As shown in FIG. 15, three burner openings 6 opposed to the burners 5 are provided on the top plate 4. Further, a fire stand 7 is placed on the top plate 4 so as to surround each burner opening 6, and at the same time, a furnace lining pan 8 overflowing with soup is placed in each burner opening 6. In addition, on the top plate 4, three actuators 9 corresponding to the three combustion engines 5 are arranged at the front center portion. As shown in Fig. 2, each operation device 9 is connected to an operation vehicle extending from a valve unit _ above each burner 5 provided in the stove body 2. In addition, three operation openings 1] L are provided corresponding to the three operators 9 which can be turned on and off. The top plate 4 is formed of a relatively thick (for example, 6 mm thick) flat plate made of metal such as aluminum. The bottom edge of the top plate 4 is provided in addition to the vent port 9 1235809 P described later; || The pad is attached to the stove opening ㈣ of the cooking table]. The outer side of the edge 3 passes through the lining, such as the top plate 4 is mounted on the conditioning table 1. On the top plate 4, a mark 12 5 as a mark is attached at the right corner of the front portion, and a dot-shaped or arc-shaped operation '^ 13 is provided as a mark around each operation opening u. In addition, the dotted portion of the operation indicator 13 indicates the flame position. The area of the top plate 4 with these marks 12, 13 ~, the area 14 in the right corner of the front part of the top plate 4 and the area 15 in the center of the front part of the top plate 4 containing 3 openings for operation are shown in Figure 4 The thickness under the cut is thinned, and 10 plus the same pressing process as the sheet metal is applied. Therefore, the logos 12 and 13 can be engraved on the top plate 4 in a raised state by performing press processing from the lower sides of the areas 14 and 15. However, it is also possible to stick the film printed with the logo on the top plate 4 as a method of attaching the logo, but in this case, the film will be peeled off due to cleaning and the like and the appearance will be damaged. In addition, the logo can be engraved by embossing from the top plate 4, but in this case, the logo will sink and easily accumulate dirt. On the other hand, in this embodiment, since the marks Η and η are engraved on the top plate 4 in a raised state, the above-mentioned problems can be solved. In addition, in this embodiment, 'the 14, 1 ^ —,, and 13 seasons are thinner because of the signs 12 and 13. Therefore, even if stamped from below, the signs 12 and 13 can be clearly marked. In addition, since the thickness of the lower surface is cut to make it thinner, the recesses formed by the four thicknesses will not appear on the top plate 4, and the appearance can be maintained well. In addition, the logo is not limited to the above-mentioned sign '12 or operation instructions, or other characters or graphics or patterns. 1235809 Furthermore, in this embodiment, in the area 15 in the center of the front portion of the thinned top plate 4, the edge portion of each operation portion opening 11 is press-processed (flange forming processing), and each operation opening 11 is pressed. The edge of the upper part forms a cylindrical protrusion 11a which is upright and upward from the upper surface of the top plate 4. Further, as shown in FIG. 2, the edge portion 16 of each of the 5 burner openings 6 is also cut to reduce the thickness thereof. Therefore, the edge portion 16 may be flange-formed so that The edge of the burner opening 6 is formed with a cylindrical protrusion 6 a standing upright from the upper surface of the top plate 4. These cylindrical protrusions 6a, 11a have the function of a bank portion surrounding each of the openings 6, 11 and prevent the overflowing soup 10 flowing onto the top plate 4 from flowing into the stove body 2 through the openings 6, 11. Further, as shown in Fig. 2, the middle portion 17 other than the left and right end portions of the rear side portion of the top plate 4 is also cut to make it thinner. In addition, the intermediate portion 17 is press-processed (stretched) so that the intermediate portion I? Protrudes on the upper surface of the top plate 4, and a ventilation which can communicate with the interior of the main body 2 of the stove 15 is ensured below the intermediate portion 17. The port 18 is adapted to take in combustion air from the burner 5 through the vent port 18. At this time, since the middle portion 17 of the rear portion of the top plate 4 has a function of covering the vent hole 18 from above, foreign matter such as overflowing soup can be prevented from falling from the vent hole 18 into the stove body 2. In addition, the vent port 18 of this embodiment is used to take in combustion air. 20 However, in a stove with a grill, the vent port 18 may be used to exhaust the exhaust gas from the grill.
