Description

The present invention relates to a gas stove and a method for manufacturing a gas stove.

A gas stove that has been widely provided conventionally has a configuration in which a top plate portion is mounted so as to close a housing portion whose upper end portion is open, and this top plate portion is an outer periphery of a plate-shaped member. Generally, a frame is attached to the part. For example, in the top plate for a cooking cooker disclosed in Patent Document 1, a frame is attached to the outer peripheral edge of the top plate. In this top plate for a cooking cooker, an elastic adhesive is interposed between a bent portion formed at the outer peripheral edge of the top plate and an inner wall portion of the frame body, and both members are adhered to each other.

Japanese Unexamined Patent Publication No. 2011-38675

However, in the top plate for a heating cooker disclosed in Patent Document 1, although an elastic adhesive is interposed between the outer peripheral edge portion of the top plate and the inner wall portion of the frame body, an elastic adhesive accommodating area is provided. Since it is not configured to close, the elastic adhesive has leaked downward. If the structure allows leakage of the adhesive in this way, a large amount of the solidified adhesive will be exposed in the vicinity of the peripheral edge on the back surface side of the top plate, which will lead to deterioration of the aesthetic appearance. Moreover, with such a configuration, when the top plate and the frame are bonded in the manufacturing process of the cooking device, they must be held in the correct positional relationship until the adhesive is surely solidified. Requires a large number of jigs. Further, at the time of manufacturing, a great deal of labor and time are required for attaching and detaching the jig.

The present invention has been made to solve the above-mentioned problems, and the top plate main body and the outer frame can be adhered to each other in a form that suppresses deterioration of the aesthetic appearance, and the top plate main body and the outer frame can be adhered to each other. The purpose of the present invention is to realize a gas stove or a method for manufacturing a gas stove, which can reduce labor and working time in the process of adhering to and.

The gas stove, which is an example of the present invention, is

The structure is such that no gap is generated between the portion and the outer frame, or the gap is kept small. Therefore, it is possible to prevent the adhesive contained between the lower extending portion and the overhanging portion from leaking from between the lower extending portion and the outer frame.
Further, since an elastic force is generated in the direction of separating the end portion of the lower extending portion and the outer edge portion of the top plate main body portion, the contact portion of the overhanging portion (the outer edge portion of the top plate main body portion) is generated. The portion that is arranged along the above and abuts on the upper surface of the top plate main body) is pressed more strongly by the upper surface of the top plate main body. Therefore, it is possible to reliably suppress the leakage of the adhesive (leakage from between the upper surface of the top plate main body and the abutting portion) due to the low adhesion between the upper surface of the top plate main body and the abutting portion. As described above, the leakage of the adhesive can be suppressed on both the upper surface side and the lower surface side of the top plate main body portion, and the deterioration of the aesthetic appearance due to the leakage can be suppressed. Further, since the above-mentioned actions and effects can be obtained by fixing the fixing portion on the lower surface side of the fixing member to the lower surface of the top plate main body portion, it is not necessary to hold the fixing member in a complicated manner by a large number of jigs when adhering. , It becomes easy to reduce the work time and labor.

Hereinafter, a desirable example of the present invention will be shown. However, the present invention is not limited to the following examples.

In the gas stove, the end portion of the lower extending portion and the outer edge portion of the top plate main body portion are adhered to the outer frame body by the first adhesive, and the lower surface side fixing portion and the lower surface of the top plate main body portion are bonded to the first adhesive. It may be adhered by a second adhesive having a faster drying rate than that.

This gas stove has a configuration in which the lower surface side fixing portion is quickly fixed to the lower surface of the top plate main body portion by the first adhesive having a relatively high drying speed, and the lower surface side fixing portion is fixed to the lower surface of the top plate main body portion. The configuration makes it easy to reduce the time and effort required to hold the product with a jig. Then, if the lower surface side fixing portion is quickly fixed to the lower surface of the top plate main body portion, the position of the fixing member with respect to the top plate main body portion can be fixed earlier, and the second adhesive is subsequently in a flowing state. Even if it is, the second adhesive is less likely to leak to both the upper surface side and the lower surface side of the top plate main body.

A gap may be formed by the outer edge of the top plate main body and the inner wall of the frame main body. The first adhesive accommodating portion may be formed by the inner wall portion of the overhanging portion and a part of the upper surface side of the top plate main body portion. The second adhesive accommodating portion may be formed by the lower extending portion and a part of the lower surface side of the top plate main body portion. The first adhesive accommodating portion and the second adhesive accommodating portion may communicate with each other through the gap portion, and may be configured as a region where the first adhesive is accumulated.

In this gas stove, the inner wall portion of the overhanging portion is adhered to the upper surface side of the top plate main body portion by the adhesive contained in the first adhesive accommodating portion, and the adhesive contained in the second adhesive accommodating portion adheres to the gas stove. Since the lower extending portion is adhered to the lower surface side of the top plate main body portion, the overhanging portion and the lower extending portion can be more reliably adhered to the top plate main body portion. Further, since the first adhesive accommodating portion and the second adhesive accommodating portion communicate with each other through the gap portion, even if the adhesive overflows from one of the accommodating portions, the gap Since it flows to the other side through the portion, it is difficult for the adhesive to leak to the outside other than both accommodating portions and the gap portion.

At least a part of the lower surface side fixing portion may be arranged along any one of the front-rear direction and the left-right direction. Then, in either the front-rear direction or the left-right direction, one side is connected to the lower extending portion and the upper surface is in contact with the lower surface of the top plate main body and is close to or without contact. A connecting portion configured as a proximity surface may be formed. Then, on the other side in the other direction, a fixing target portion may be formed in which the second adhesive is applied to the upper surface and the upper surface is fixed to the lower surface of the top plate main body portion. Further, in the other direction, the upper surface of the connecting portion and the fixing target portion is arranged at a position lower than the proximity surface of the connecting portion, and a gap is formed between the connecting portion and the lower surface of the top plate main body portion. The portions may be formed.

In this way, of the lower surface side fixed portion, one side of the region arranged along any one of the front-rear direction and the left-right direction (one in the front-rear direction or the left-right direction or the other direction). If a connecting portion having a proximity surface is arranged on the side), a fixing target portion is arranged on the other side (the other side in the other direction), and a retractable part is arranged between the connecting portion and the fixing target portion. , It becomes difficult to mix the second adhesive for adhering the fixing target portion and the first adhesive for adhering the lower extending portion. That is, even if the second adhesive tries to flow into the outer edge side of the top plate main body portion, it is absorbed into the evacuation allowance portion, so that the situation where the second adhesive enters the downward extending portion is less likely to occur. Similarly, even if the first adhesive tries to flow into the center side of the top plate main body portion, it is absorbed into the evacuation allowance portion, so that the situation where the first adhesive enters the fixing target portion side is less likely to occur.

The housing portion includes a pair of side wall portions and a rear wall portion arranged around the accommodation space for accommodating the gas burner, and corresponds to the upper end portion of at least one of the pair of side wall portions and the rear wall portion to be fixed. A slit portion extending in the direction in which the wall portion to be fixed extends may be formed. At least one of the fixing members may include a protruding plate that bends from the downward extending portion and projects downward. In a closed state in which the top plate portion closes the housing portion, the projecting plate and the fixing target wall portion are connected by a connecting member in a state where the protruding plate is inserted into the slit portion and arranged on the inner wall surface side of the fixing target wall portion. It may be fixed.

In the gas stove configured in this way, the protruding plate of the top plate portion is inserted into the slit portion formed at the upper end portion (upper end portion of the fixing target wall portion) of the housing portion, and the inner wall surface side of the fixing target wall portion is inserted. Since the top plate portion and the housing portion are assembled in the form arranged in, the connecting portion of the top plate portion (the portion for connecting with the housing portion) can be hidden inside the housing portion, and the connecting portion can be hidden. It is possible to suppress the deterioration of aesthetics caused by being visually recognized from the outside. Further, since the top plate portion can be formed in a form in which the protruding plate is extended from a part of the fixing member (lower extending portion) bonded to the lower surface portion of the top plate main body portion, the top plate portion can be formed. It is not necessary to configure the entire peripheral edge portion as a frame to surround the upper end portion of the housing portion from the outside, and it becomes easier to configure the peripheral edge portion of the top plate portion to be thinner. Therefore, it is possible to adopt a design in which the peripheral portion is thinly configured, and such a design can enhance the aesthetic appearance. Further, since the protrusion plate provided on the top plate portion is assembled so as to be inserted into the slit portion formed at the upper end portion of the housing portion, the top plate portion is lowered from directly above the housing portion and assembled. It is not necessary to adopt a mounting method in which the top plate portion is greatly rotated. Therefore, it is difficult for the opening and the gas burner to interfere with each other in the process of placing the top plate on the housing, and it is unlikely that the user will be forced to take time and effort due to the interference in the mounting process. ..

(Center side) extends along the direction of the side edge 46.

A groove portion 173 is formed as a horizontal groove along the horizontal direction on the inner wall portion of the frame main body portion 170 on the top plate main body portion 30A side. The groove portion 173 extends along the outer edge portion (side edge portion 46 in the example of FIG. 22) of the top plate main body portion 30A at a position lower than the lower surface of the top plate main body portion 30A. In the right end side frame portion 91 shown in FIG. 22, the groove portion 173 is configured as a groove recessed on one side (right side) in the left-right direction and as a groove extending in the front-rear direction.

The bent member 30C (fixing member) is connected to the lower surface side fixing portion 111C fixed to the lower surface of the top plate main body 30A (specifically, the lower surface of the plate-shaped member 40) and the lower surface side fixing portion 111C. It includes a lower extending portion 111D that extends downward from the lower surface side fixing portion 111C and is arranged so that the end portion fits into the groove portion 173 of the outer frame body 30B. Then, an elastic force is generated in the direction of separating the end portion of the lower extension portion 111D and the side edge portion 46 of the top plate main body portion 30A, and the end portion and the ceiling of the lower extension portion 111D. The side edge portion 46 of the plate body portion 30A is adhered to the outer frame body 30B by an adhesive (second adhesive 182) accommodated between the downward extending portion 111D and the overhanging portion 171. In this state, an elastic force in the direction of separating the end portion of the lower extending portion 111D and the side edge portion 46 of the top plate main body portion 30A is continuously generated, so that the lower side is shown as shown by the arrow F1 in FIG. A force for pressing the outer frame body 30B downward is continuously generated near the end of the extending portion 111D.

As shown in FIG. 22, the first adhesive accommodating portion 191 is formed by the inner wall portion 171B of the overhanging portion 171 and a part of the upper surface side of the top plate main body portion 30A, and the downward extending portion 111D and the top plate main body. The second adhesive accommodating portion 192 is formed by a part of the lower surface side of the portion 30A, and the gap portion 190 is formed by the side edge portion 46 of the top plate main body portion 30A and the inner wall portion of the frame main body portion 170. .. Then, the first adhesive accommodating portion 191 arranged on the upper side and the second adhesive accommodating portion 192 arranged on the lower side communicate with each other vertically through the gap 190, and the first adhesive 181 is accumulated. It is configured as an area. With such a configuration, the end portion of the lower extending portion 111D and the side edge portion 46 of the top plate main body portion 30A are adhered to the outer frame body 30B by the first adhesive 181.

On the other hand, the lower surface side fixing portion 111C and the lower surface of the top plate main body portion 30A are bonded by the second adhesive 182, which has a faster drying speed than the first adhesive 181. FIG. 22 shows the lower surface side fixing portion 111C which is a part of the lower surface side fixing portion (lower surface side fixing portion 111C, 111E) of the bent member 30C (fixing member). The lower surface side fixing portion 111C forming a part of the region is arranged along one of the front-rear direction and the left-right direction (specifically, the front-rear direction), and is arranged in the other direction (specifically, the front-rear direction). In the left-right direction), one side (the side connected to the lower extension portion 111D) is connected to the lower extension portion 111D and the upper surface is in contact with or in contact with the lower surface of the top plate main body portion 30A. A connecting portion 121 configured as a proximity surface 121A that is close to each other is formed. Then, on the other side (the side opposite to the outer frame body 30B) in the other direction (left-right direction), the second adhesive 182 is applied to the upper surface and the upper surface is fixed to the lower surface of the top plate main body 30A. The fixing target portion 122 is formed. Further, in the other direction (left-right direction), the upper surface is arranged below the proximity surface 121A of the connecting portion 121 and with the lower surface of the top plate main body portion 30A between the connecting portion 121 and the fixing target portion 122. An evacuation allowance portion 123 is formed in which a gap is formed between the two.

Next, a manufacturing method for manufacturing the gas stove 1 described above will be described.
In addition, in FIGS. 23 and 24, the step of adhering the outer frame body 30B, the top plate main body portion 30A, and the first side edge reinforcing portion 71A of the bent member 30C will be described. The portion 71B can also be bonded by the same structure and the same method, and the other fixing members (bent member 30D, long plate-shaped member 30E) are also bonded by the same structure and the same method as the bonding of the bent member 30C. be able to.

First, as shown in FIG. 23, an outer frame body 30B, a top plate main body 30A, and a bent member 30C are prepared. These parts can be manufactured by various known manufacturing methods, and the specific manufacturing method does not matter. In the following description, of the plate-shaped members 40 constituting the top plate main body 30A, the surface that becomes the upper surface 40A (FIG. 22) when it is a finished product is the second surface, and when it is a finished product. The surface that becomes the lower surface 40B (FIG. 22) is the first surface.

After forming each component as shown in FIG. 23, among these components, the lower extending portion 111D (one-side extending portion) of the bent member 30C and the outer edge portion of the top plate main body portion 30A (plate-shaped member in FIG. 23). The first adhesive 181 is applied to at least one of the side edge portion 46) of the 40 and the portion on the inner wall portion side of the outer frame body 30B (for example, near the inner wall portion 171B of the overhanging portion 171). In the example of FIG. 23, the bent member 30C, the top plate main body 30A, and the outer frame 30B are turned upside down, and the first adhesive 181 is applied to the vicinity of the inner wall 171B of the overhanging portion 171 in the outer frame 30B. There is.

Further, at least one of the lower surface side fixing portion 111C (first surface side fixing portion) of the bent member 30C and the fixing target portion of the top plate main body portion 30A (the portion to be fixed of the lower surface side fixing portion 111C) is the first. A second adhesive 182, which has a faster drying rate than the first adhesive 181, is applied. The second adhesive 182 may be an adhesive having a faster drying speed than the first adhesive 181. For example, a quick-drying adhesive such as an ultraviolet curable adhesive can be used as the second adhesive 182. .. In the example of FIG. 23, the second adhesive 182 is applied to one surface of the fixing target portion 122 of the bent member 30C (the surface to be adhered to the first surface (the surface to be the lower surface 40B) of the plate-shaped member 40). ..

Then, as shown in FIG. 24, the end portion of the lower extending portion 111D (one-side extending portion) is fitted into the groove portion 173, and the contact portion 171A of the overhanging portion 171 is placed on the second surface of the top plate main body portion 30A. The first adhesive 181 was housed in a space surrounded by the lower extending portion 111D, the top plate main body portion 30A, and the overhanging portion 171 in contact with (the surface of the plate-shaped member 40 which is the upper surface 40A). In this state, the second adhesive 182 is interposed between the lower surface side fixing portion 111C and the fixing target portion in the top plate main body 30A, and the end of the lower extending portion 111D and the side of the top plate main body 30A. Positioning is performed in a state where an elastic force is generated in a direction that separates the edge portion 46 from the edge portion 46, and the bending member 30C (fixing member) is held while being restricted from relative movement with respect to the top plate main body portion 30A. Then, the first adhesive 181 and the second adhesive 182 are dried while being held in this way. Since the second adhesive 182 has a faster drying rate than the first adhesive 181, the second adhesive 182 dries and solidifies early in the drying step, and then the second adhesive 182 solidifies. Become.

Next, the main effects of this configuration will be illustrated.
As shown in FIG. 22, in the gas stove 1 described above, a groove portion 173 is provided on the inner wall portion of the outer frame body 30B at a position below the lower surface 40B of the top plate main body 30A along the outer edge of the top plate main body 30A. It is provided. On the other hand, the bent member 30C (fixing member) has a lower surface side fixing portion 111C fixed to the lower surface of the top plate main body 30A and a groove portion extending downward from the lower surface side fixing portion 111C and having an end portion of the outer frame body 30B. It is provided with a downward extending portion 111D arranged so as to fit inside. Then, the end portion of the lower extending portion 111D and the outer edge portion of the top plate main body portion 30A are outered by the adhesive (first adhesive 181) accommodated between the lower extending portion 111D and the overhanging portion 171. It is adhered to the frame body 30B. In this way, the lower extending portion 111d is arranged below the top plate main body 30A, and the end of the lower extending portion 111D is arranged so as to fit into the groove 173 of the outer frame 30B. The structure is such that no gap is generated between the lower extending portion 111D and the outer frame body 30B, or the gap is kept small. Therefore, it is possible to prevent the first adhesive 181 housed between the lower extending portion 111D and the overhanging portion 171 from leaking from between the lower extending portion 111D and the outer frame body 30B. Such an effect also occurs in other fixing members.

Further, since an elastic force is generated in the direction of separating the end portion of the lower extending portion 111D and the outer edge portion of the top plate main body 30A, the contact portion 171A (top plate main body) of the overhanging portion 171 is generated. A portion that is arranged along the outer edge portion of the portion 30A and abuts on the upper surface 40A of the top plate main body 30A) is strongly pressed against the upper surface 40A of the top plate main body 30A. Therefore, the leakage of the adhesive (leakage from between the upper surface of the top plate main body 30A and the abutting portion) due to the low adhesion between the upper surface 40A of the top plate main body 30A and the abutting portion 171A is ensured. As described above, the leakage of the adhesive can be suppressed on both the upper surface side and the lower surface side of the top plate main body 30A, and the deterioration of the aesthetic appearance due to the leakage can be suppressed. Further, by fixing the lower surface side fixing portion 111C of the bent member 30C (fixing member) to the lower surface 40B of the top plate main body portion 30A, the above-mentioned actions and effects can be produced. This eliminates the need to hold the jig in a complicated manner, which makes it easier to reduce work time and labor. Such an effect also occurs in other fixing members.

As shown in FIG. 22, the end portion of the lower extending portion 111D and the outer edge portion of the top plate main body portion 30A are adhered to the outer frame body 30B by the first adhesive 181 and the lower surface side fixing portion 111C and the top plate main body portion 30A are adhered to each other. The lower surface 40B of the above surface is adhered to the lower surface 40B by a second adhesive 182 having a drying speed faster than that of the first adhesive 181. The gas stove 1 has a configuration in which the lower surface side fixing portion 111C is quickly fixed to the lower surface 40B of the top plate main body 30A by the first adhesive 181 having a relatively high drying speed, and the lower surface side fixing portion 111C is quickly fixed to the top plate main body. The configuration is such that it is easy to reduce the time and effort required to hold the portion 30A by a jig until it is fixed to the lower surface 40B of the portion 30A. Then, if the lower surface side fixing portion 111C is quickly fixed to the lower surface 40B of the top plate main body 30A, the position of the bent member 30C (fixing member) with respect to the top plate main body 30A can be fixed earlier. Even if the second adhesive 182 is subsequently in a fluid state, the second adhesive 182 is less likely to leak to both the upper surface side and the lower surface side of the top plate main body 30A. Such an effect also occurs in other fixing members.

In the example of FIG. 22, the gap portion 190 is formed by the outer edge portion of the top plate main body portion 30A and the inner wall portion of the frame main body portion 170. The first adhesive accommodating portion 191 is formed by the inner wall portion 171B of the overhanging portion 171 and a part of the upper surface side of the top plate main body portion 30A. Further, the lower extending portion 111D and a part of the lower surface side of the top plate main body portion 30A constitute a second adhesive accommodating portion 192. Then, the first adhesive accommodating portion 191 and the second adhesive accommodating portion 192 communicate with each other via the gap portion 190, and are configured as a region where the first adhesive 181 is accumulated. In this gas stove 1, the inner wall portion 171B of the overhanging portion 171 is adhered to the upper surface side of the top plate main body portion 30A by the first adhesive 181 accommodated in the first adhesive accommodating portion 191 to accommodate the second adhesive. Since the lower extending portion 111D is adhered to the lower surface side of the top plate main body 30A by the adhesive contained in the portion 192, the overhanging portion 171 and the lower extending portion 111D are more reliably attached to the top plate main body 30A. Can be glued to. Further, since the first adhesive accommodating portion 191 and the second adhesive accommodating portion 192 communicate with each other through the gap portion 190, it is assumed that the adhesive overflows from one of the accommodating portions. However, since the adhesive flows to the other side through the gap 190, it is difficult for the adhesive to leak to the outside other than both the accommodating portions and the gap.

At least a part of the lower surface side fixing portion that forms a part of the fixing member is arranged along one of the front-rear direction and the left-right direction, and is downward on one side in any other direction. A connecting portion 121 is formed which is connected to the side extending portion and whose upper surface is in contact with the lower surface of the top plate main body 30A and is configured as a proximity surface which is close to or without contact with the lower surface, and is formed on the other side in the other direction. Is formed by applying a second adhesive 182 to the upper surface and forming a fixing target portion 122 whose upper surface is fixed to the lower surface of the top plate main body 30A, and between the connecting portion 121 and the fixing target portion 122 in the other direction. Is formed with an evacuation allowance portion 123 in which the upper surface is arranged below the proximity surface 121A of the connecting portion 121 and a gap is formed between the upper surface and the lower surface of the top plate main body portion 30A. In this way, the connecting portion 121 having the proximity surface 121A on one side (one side in either the front-rear direction or the left-right direction) is arranged, and the fixing target is on the other side (the other side in the other direction). If the portion 122 is arranged and the retractable portion 123 is arranged between the connecting portion 121 and the fixing target portion 122, the second adhesive 182 for adhering the fixing target portion 122 and the downward extending portion are adhered to each other. It becomes difficult to mix with the first adhesive 181 to be mixed. That is, even if the second adhesive 182 tries to flow into the outer edge side of the top plate main body 30A, it is absorbed into the evacuation allowance portion 123, so that the situation where the second adhesive 182 enters the downward extending portion is unlikely to occur. Become. Similarly, even if the first adhesive 181 tries to flow into the center side of the top plate main body 30A, it is absorbed into the evacuation allowance portion 123, so that the first adhesive 181 may enter the fixing target portion 122 side. It becomes difficult.

Further, in the gas stove 1, the protruding plate of the top plate portion 30 is inserted into the slit portion formed at the upper end portion (upper end portion of the fixing target wall portion) of the housing portion 2 and is placed on the inner wall surface side of the fixing target wall portion. Since the top plate portion 30 and the housing portion 2 are assembled in the arranged form, the connecting portion (the portion for connecting to the housing portion 2) of the top plate portion 30 can be hidden inside the housing portion 2. It is possible to suppress the deterioration of the aesthetic appearance due to the connected portion being visually recognized from the outside. Further, since the top plate portion can be formed in a form in which the protruding plate is extended from a part of the fixing member (lower extending portion) bonded to the lower surface portion of the top plate main body portion 30A, the top plate portion can be formed. It is not necessary to configure the entire peripheral edge portion of the top plate portion 30 as a frame body so as to surround the upper end portion of the housing portion from the outside, and it becomes easier to configure the peripheral edge portion of the top plate portion 30 to be thinner. Therefore, it is possible to adopt a design in which the peripheral portion is thinly configured, and such a design can enhance the aesthetic appearance. Further, since the protruding plate provided on the top plate portion 30 is assembled so as to be inserted into the slit portion formed at the upper end portion of the housing portion 2, the top plate portion 30 is assembled from directly above the housing portion 2. It is possible to mount the top plate portion 30 by lowering it, and it is not necessary to adopt a mounting method such as rotating the top plate portion 30 greatly. Therefore, in the process of placing the top plate portion 30 on the housing portion 2, the opening and the gas burner are less likely to interfere with each other, and the user may be forced to take time and effort due to the interference in the mounting process. It is unlikely to occur.
