Description

The present invention relates to a cooking device in which a grill plate on which an object to be cooked is placed is housed in a grill chamber and cooked.

Conventionally, a pair of left and right lower fire burners extending in the front-rear direction are provided below the inside of the left and right side walls of the grill, and combustion exhaust is ejected from the flame holes of these lower fire burners toward the left and right center of the grill. There is known a cooking device that cooks an object to be cooked such as meat and fish placed on a grill. In the above-mentioned cooker, secondary air rectifying plates are provided on the inner surfaces of the left and right side walls of the grill, and secondary air is guided from the outside of the grill to the vicinity of the flame holes of each lower fire burner, and the secondary air flow is used to guide the secondary air from the flame holes. The ejected combustion exhaust is blown to the space below the grill in the central left and right sides of the grill (for example, Patent Document 1).

By the way, in order to diversify the cooking menu and improve the cleanability of the inside of the grill, a cooking cooker using a grill plate instead of the grill has been proposed (for example, Patent Document 2). In this type of cooker, a grill plate is housed so as to cover a lower heat burner arranged in the grill chamber. Therefore, the lower surface of the object to be cooked placed on the grill plate is heated mainly by the heat transfer of the grill plate heated by the lower heat burner.

However, when the grill plate as described above is used, the space inside the grill is separated into upper and lower parts by the grill plate, so that the combustion exhaust gas ejected from the lower heat burner stays in the space below the grill plate and the grill plate. It becomes difficult for the combustion exhaust to reach the space above. As a result, even if the heating power of the lower heat burner is weakened, the temperature inside the grill plate and grill becomes high, and in the case of roast beef, grilled potatoes, and other items to be cooked that require long-term heating at low temperatures, the bottom surface of the item to be cooked Overcooking is likely to occur. In addition, if the heating power of the lower heat burner is weakened in order to prevent overcooking of the lower surface of the cooked object in low-temperature cooking, it becomes more difficult for the combustion exhaust to flow to the upper space inside the grill, so the upper surface of the cooked object is raised. Cannot be heated sufficiently. In addition, when a grill plate is used, the ventilation resistance inside the grill is greater than that of a grill made of wire and has a large gap, so sufficient secondary air is provided from the outside of the grill to the flame hole of the lower fire burner. There is a problem that the flame cannot be supplied to the grill, resulting in an oxygen deficiency flame, and the flame overflows to the outside of the grill and combustion failure is likely to occur.

Japanese Unexamined Patent Publication No. 2008-57842 JP 2015-164494

The present invention has been made in view of the above problems, and an object of the present invention is a cooking device capable of cooking the upper and lower sides of an object to be cooked placed on a grill plate in a well-balanced manner at a low temperature with a lower heat burner. Is to provide.

The present invention
A grill storage that houses the grill plate on which the food to be cooked is placed,
It is equipped with a pair of left and right lower fire burners located outside the left and right side walls of the grill.
The left and right lower fire burners burn from the outside of the left and right side walls of the grill to the left and right side ends of the grill plate housed in the grill through the inlets provided on the left and right side walls of the grill. It is a cooker that ejects exhaust.

According to the above-mentioned cooker, a pair of left and right lower heat burners are arranged on the outside of the left and right side walls of the grill, and the left and right lower heat burners are respectively passed through the introduction ports provided on the left and right side walls of the grill. Since the combustion exhaust is ejected from the outside of the left and right side walls toward the left and right side ends of the grill plate housed in the grill, the combustion exhaust that comes into contact with the left and right side ends of the grill plate is above and below the grill plate. Divided into. As a result, the lower surface of the grill plate is heated by the combustion exhaust gas that is divided into the space below the grill plate in the grill chamber. On the other hand, the combustion exhaust gas diverted above the grill plate wraps around in the upper space inside the grill and heats the upper surface of the grill plate and the upper surface of the object to be cooked from above. Therefore, it is possible to prevent the combustion exhaust from the lower heat burner from concentrating under the grill plate as in the conventional case and the temperature inside the grill plate and the grill chamber from rising excessively, which is suitable for low temperature cooking. The environment can be formed. Therefore, even if the heating power of the lower heat burner is weakened, both the upper and lower sides of the object to be cooked placed on the grill plate can be heated in a well-balanced manner. In addition, due to the diversion of the combustion exhaust to the top and bottom of the grill plate, it becomes difficult for the combustion exhaust of the lower heat burner to stay below the grill plate, and it becomes easier for it to escape above the grill plate, so that it is stable around the flame hole. The next air can be supplied. As a result, it is possible to prevent the flame from overflowing to the outside of the grill due to the oxygen deficiency flame of the lower heat burner and the combustion failure, and to stably heat the food to be cooked.

Preferably, in the above cooking device,
The left and right lower heat burners are configured so that the combustion exhaust gas ejected toward the left and right side ends of the grill plate is divided into the upper and lower parts of the grill plate.

According to the above-mentioned cooking cooker, the combustion exhaust ejected from the left and right lower heat burners toward the left and right side ends of the grill plate is smoothly divided into the upper and lower parts of the grill plate, so that the thermal power of the lower heat burner is weakened. However, both the upper and lower sides of the object to be cooked placed on the grill plate can be heated in a well-balanced manner.

Preferably, in the above cooking device,
The left and right lower fire burners each have a plurality of slit-shaped flame holes arranged so as to be vertically offset.

According to the above-mentioned cooking cooker, since the left and right lower heat burners each have a plurality of flame holes arranged so as to be vertically offset, the combustion exhaust can be more smoothly divided into the upper and lower parts of the grill plate. Further, since the left and right lower flame burners each have slit-shaped flame holes, the combustion flame formed in each flame hole can be shortened, and the flame retention property can be improved. As a result, even if the thermal power of the lower heat burner is weakened, stable combustion can be performed with a small combustion flame. In addition, since the shortened combustion flame is stably formed in the flame hole, the combustion flame is less likely to fluctuate due to the lack of secondary air even when the grill door is opened, and the combustion exhaust to the outside of the grill storage. Overflow can be reduced.

Preferably, in the above cooking device,
The left and right lower fire burners each have a plurality of slit-shaped diagonally upward flame holes that open diagonally upward and inward, and a plurality of slit-shaped diagonally downward flame holes that open diagonally downward and inward.

According to the above-mentioned cooker, the left and right lower heat burners each have a plurality of slit-shaped diagonally upward flame holes that open diagonally upward and inward, and a plurality of slit-shaped diagonally downward and inwardly open flame holes. Since it has a diagonally downward flame hole, the combustion exhaust can be more smoothly divided into the upper and lower parts of the grill plate.

Preferably, in the above cooking device,
The left and right lower fire burners each have a plurality of slit-shaped flame holes that open from the inner end surface of the lower fire burner to the upper surface, and a plurality of slits that open from the inner end surface of the lower fire burner to the lower surface. It has a shaped flame hole.

According to the above-mentioned cooking cooker, the left and right lower heat burners each have a plurality of slit-shaped flame holes that open from the inner side end surface of the lower heat burner to the upper surface, and the lower side from the inner side end surface of the lower heat burner. Since it has a plurality of slit-shaped flame holes that open over the grill plate, the combustion exhaust can be more smoothly divided into the upper and lower parts of the grill plate.

Preferably, in the above cooking device,
The grill plate has a diversion portion at each of the left and right side ends, which diverts the combustion exhaust gas ejected from the left and right lower heat burners to the upper and lower sides of the grill plate.

According to the above-mentioned heating cooker, the combustion exhaust gas ejected from the left and right lower heat burners comes into contact with the diversion portion, so that the combustion exhaust gas can be more smoothly divided into the upper and lower parts of the grill plate.

As described above, according to the present invention, the combustion exhaust gas ejected from the pair of left and right lower heat burners arranged on the outside of the left and right side walls of the grill storage is divided into the upper and lower parts of the grill plate housed in the grill storage. , Both the upper and lower sides of the object to be cooked placed on the grill plate can be cooked at a low temperature in a well-balanced manner.

Hereinafter, the cooking cooker according to the embodiment of the present invention will be specifically described with reference to the accompanying drawings.
FIG. 1 is a schematic perspective view showing a gas stove which is an example of a cooking cooker according to the present embodiment. As shown in FIG. 1, the cooking cooker includes a plurality of stove burners 1 provided on the upper surface of the top plate 9, and a grill 2 for cooking using the grill plate 80.

As shown in FIGS. 1 and 2, the grill 2 is mounted inside the stove body 10 and closes the rectangular box-shaped grill 20 that opens forward and the front opening 100 of the grill 20 from the front. A grill door 5 is provided. A connecting plate 210 extends toward the inside of the grill storage 20 below the rear surface of the grill door 5, and a support frame 220 that supports the grill plate 80 from below is connected to the connecting plate 210. As a result, by pulling the grill door 5 toward you, the grill plate 80 is pulled out in front of the grill storage 20 together with the support frame 220, and by pushing the grill door 5 backward, the grill plate 80 is pulled out together with the support frame 220 in the grill storage. It is configured to be housed within 20. In this specification, the side on which the grill door 5 is provided is the front surface, and the direction in which the grill door 5 and the back side of the grill storage 20 face each other when viewed from the grill door 5 side is the front-rear direction, and the grill storage. The width direction of the 20 is called the left-right direction, and the height direction of the grill 20 is called the up-down direction.

The operation unit formed on the left side of the grill door 5 is provided with a grill switch 41 having a point / fire extinguishing function and a thermal power adjustment function of upper and lower burners 56 and 55, which will be described later, and a kangaroo type operation unit 40 below the switch 41. Has been done. The operation unit 40 is configured to be tilted toward the front so that the user can operate the operation unit 40 by pushing and operating the front panel 401 below the operation unit. Further, when the user closes the front panel 401, the operation unit 40 is stored in the stove body 10.

As shown in FIGS. 2 and 3, the upper wall 24 of the grill 20 is provided with a top heat burner 56 for heating the food to be cooked from above. The upper fire burner 56 is, for example, a surface combustion type ceramic burner whose lower surface is made of a ceramic plate, and a flame hole 560 is provided on the lower surface of the plate. Therefore, when the fuel gas and the primary air are supplied from the mixing pipe (not shown) and the top burner 56 is ignited, a combustion flame of the fuel gas is formed on the lower surface of the plate body, and its radiant heat and combustion exhaust are formed. Is radiated downward in the grill 20. Although not shown, the flame hole 560 of the top burner 56 faces an electrode portion of an ignition electrode for igniting a fuel gas and a thermocouple for detecting a combustion flame.

In the lower regions of the left and right side walls 21 and 22 of the grill chamber 20, introduction ports 201 and 202 long in the front-rear direction are opened. The left and right side walls of the introduction ports 201 and 202 are arranged so that the center in the front-rear direction is located in front of the center in the front-rear direction of the grill plate 80 when the grill plate 80 is housed in the grill storage 20. It is formed at a position closer to the front of 21 and 22.

On the outside of the left and right side walls 21 and 22 of the grill chamber 20, a pair of left and right lower fire burners 55 extending in the front-rear direction along the left and right side walls 21 and 22 are arranged. Each lower fire burner 55 has, for example, a plurality of openings forming a slit-shaped flame hole 550 by punching a predetermined portion, and a single metal plate formed is bent in the vicinity of the openings and becomes substantially straight tubular. It is formed by molding and joining the ends of a metal plate. Since the left and right lower fire burners 55 have the same configuration except that they are symmetrical, the configuration of the lower fire burner 55 and its surroundings will be described by taking the left lower fire burner 55 as an example.

As shown in FIGS. 2 to 4, the lower fire burner 55 includes a burner main body 500 formed in an elongated flat plate shape and a flame hole 550 formed in the inner edge portion 570 on the inner side in the left-right direction of the burner main body 500. It has an inflow portion 551 into which a gas nozzle (not shown) formed at the rear end portion is inserted, and a horizontally extending flange portion 552 to which a metal plate is joined to the outer side in the left-right direction of the burner main body 500. The lower fire burner 55 is supported and fixed to the stove body 10 in a posture in which the inner edge portion 570 of the burner body 500 faces the introduction port 201 and the burner body 500 is substantially horizontal.

An exhaust overflow prevention cover 600 having a substantially L-shaped cross section is connected to the outer surface of the left side wall 21 of the grill storage 20 so as to cover the lower fire burner 55 from above and from the left outside, and the upper edge of the opening of the introduction port 201. A straightening vane 601 extending diagonally upward and outward toward the upper side of the lower fire burner 55 is connected to the lower heat burner 55. A certain size of gap is formed between the lower end of the exhaust overflow prevention cover 600 and the upper surface of the lower fire burner 55, and between the inner surface of the exhaust overflow prevention cover 600 and the outer end of the straightening vane 601. ing. Therefore, when the lower heat burner 55 is ignited, the secondary air flowing in from the gap between the exhaust overflow prevention cover 600 and the lower heat burner 55 is supplied from above the lower heat burner 55 to the vicinity of the flame hole 550 by the rectifying plate 601. Then, the combustion exhaust is blown to a distant place in the grill chamber 20 by the secondary air. As a result, the left and right central portions on the lower surface of the grill plate 80 can be efficiently heated.

An exhaust opening 11 communicating with the exhaust passage 300 is provided in the upper rear portion of the grill chamber 20. An exhaust duct 30 is continuously provided on the rear wall 25 of the grill chamber 20, and the exhaust duct 30 constitutes an exhaust passage 300.

As shown in FIGS. 4 and 5, the inner edge portion 570 of the burner main body 500 is formed in a substantially U-shaped vertical cross section, and the upper corner portion 555 and the lower corner portion 556 are each elongated in the vertical direction. A plurality of slit-shaped flame holes 550 are formed.

The plurality of flame holes 550 are divided into an upper corner portion 555 and a lower corner portion 556 and alternately opened along the inner edge portion 570 of the lower fire burner 55 by a predetermined number (here, 6 holes). .. That is, the plurality of flame holes 550 are arranged so as to be offset vertically from the inner edge portion 570. Further, the flame hole 550 of the upper corner portion 555 is formed in a substantially L-shaped notch from the upper surface 505 of the inner edge portion 570 to the side surface 507, and the flame hole 550 of the lower corner portion 556 is the lower surface of the inner edge portion 570. A notch is formed in a substantially L shape from 506 to the side surface 507. Further, the lower end of the flame hole 550 of the upper corner portion 555 and the upper end of the flame hole 550 of the lower corner portion 556 are cut out to substantially the same height at the upper and lower centers of the side surface 507. That is, each flame hole 550 is opened from the upper and lower center of the side surface 507, which is the inner end surface of the lower fire burner 55, to any one of the upper and lower surfaces 505 and 506 following the side surface 507.

Therefore, as shown in FIG. 5, the fuel gas supplied to the burner main body 500 together with the primary air is ejected from the flame hole 550 of the upper corner portion 555 slightly upward from the horizontal, and is ejected from the flame hole 550 of the lower corner portion 556. It is ejected downward rather than horizontally. As a result, when the lower fire burner 55 is ignited by a spark discharge from an ignition electrode (not shown), the combustion exhaust from the lower fire burner 55 is discharged from the grill through the introduction port 201 opened in the left wall 21 of the grill 20. It is ejected so as to diffuse vertically inward in the left-right direction of 20.

As shown in FIG. 4, a predetermined flame hole non-forming portion 558 is provided between the flame hole 550 group of the upper corner portion 555 and the flame hole 550 group of the lower corner portion 556. Further, the flame hole 550 group of the upper corner portion 555 is divided into front and rear by a predetermined number (here, 3 holes each), and the flame hole non-forming portion 558 is also arranged between the flame hole 550 groups before and after these. It is provided. Similarly, the flame hole 550 group of the lower corner portion 556 is also divided into front and rear by a predetermined number, and a predetermined flame hole non-forming portion 558 is provided between the front and rear flame hole 550 groups. ..

Returning to FIGS. 1 to 3, the grill plate 80 is made of an aluminum molded body or a cast body having excellent heat transfer properties, and the upper surface thereof is surface-treated with fluororesin or the like. The grill plate 80 has a substantially rectangular shape in a plan view. On the upper surface of the grill plate 80, a food material placing portion 85 is provided in which a plurality of upwardly convex ridges 82 extending in the left-right direction are formed at predetermined intervals in the front-rear direction. The left and right ends of the grill plate 80 are provided with side ends 83 having an ascending slope from the left and right outer ends of the food placing portion 85 in the diagonally upward and outward directions. The left and right side end portions 83 are connected by the front and rear end portions of the grill plate 80. Further, on the outer surface 830 of the left and right side end portions 83, a diversion projection (current diversion portion) 831 having a substantially triangular cross section in the front view is formed so as to project outward in the left-right direction of the grill plate 80. The diversion protrusion 831 extends substantially in the front-rear direction of the left and right side end portions 83 (see FIG. 1).

When the grill plate 80 is housed in the grill storage 20, the grill plate 80 is supported from below by the support frame 220 so that the left and right side end portions 83 face the introduction ports 201 and 202. Therefore, as described above, the combustion exhaust gas ejected from the lower heat burner 55 through the introduction ports 201 and 202 into the grill chamber 20 contacts the side end portion 83 of the grill plate 80 and is inclined diagonally upward and outward. It is divided into the upper and lower parts of the grill plate 80 by the side end portion 83. In particular, since the side end portion 83 is formed with a diversion projection 831 projecting outward in the left-right direction, the diversion of the grill plate 80 up and down along the diversion projection 831 is promoted.

The combustion exhaust gas diverted downward of the side end portion 83 as described above flows through the space S2 below the grill plate 80 toward the left and right central portions along the lower surface of the grill plate 80, and causes the grill plate 80 to flow. Heat from below. On the other hand, the combustion exhaust gas diverted toward the upper side of the side end portion 83 passes through the gap between the grill plate 80 and the left and right side walls 21 and 22 of the grill storage 20 and wraps around the space S1 above the grill plate 80. , The upper surface of the grill plate 80 and the upper surface of the object to be cooked are heated from above.

According to the heating cooker of the present embodiment, the pair of left and right lower heat burners 55 arranged on the outside of the left and right side walls 21 and 22 of the grill storage 20 are directed toward the inside of the grill storage 20 via the introduction ports 201 and 202. Since the ejected combustion exhaust comes into contact with the side end 83 of the grill plate 80, the combustion exhaust can be diverted above and below the grill plate 80 at both left and right ends in the grill storage 20. In particular, the diversion projection 831 provided on the side end 83 of the grill plate 80 can promote the vertical diversion of the combustion exhaust gas to the grill plate 80. Therefore, the combustion exhaust can be sufficiently distributed on both the upper and lower sides of the grill plate 80. As a result, the grill plate 80 can be heated from below by the combustion exhaust gas divided below the grill plate 80, and the upper surface of the grill plate 80 and the food to be cooked by the combustion exhaust gas divided above the grill plate 80. The upper surface can be heated. Therefore, it is possible to prevent the combustion exhaust gas from the lower heat burner 55 from concentrating under the grill plate 80 and the temperature inside the grill plate 80 and the grill chamber 20 from rising excessively, which is suitable for low temperature cooking. A temperature environment can be formed. Therefore, for example, when it is desired to cook an object to be cooked at a low temperature for a long time such as roast beef, the amount of fuel gas supplied to the lower heat burner 55 is reduced with the upper heat burner 56 extinguished, and the lower heat is reduced. Even if the thermal power of the burner 55 is weakened, both the upper and lower surfaces of the object to be cooked can be heated in a well-balanced manner by the combustion exhaust ejected from the lower heat burner 55.

Further, according to the heating cooker of the present embodiment, since the combustion exhaust from the lower flame burner 55 is divided into the upper and lower parts of the grill plate 80, the grill plate 80 housed in the grill plate 20 divides the combustion exhaust into the grill plate 80. Even if the ventilation resistance of the grill is increased, the secondary air can be stably supplied to the periphery of the flame hole 550, the lower flame burner 55 can be stably burned, and combustion defects can be prevented.

Further, according to the heating cooker of the present embodiment, the left and right lower heat burners 55 have a plurality of flame holes 550 that open from the upper and lower centers of the side surface 507 to the upper surface 505, respectively, and the lower surface from the upper and lower centers of the side surface 507. It has a plurality of flame holes 550 that open over 506, and since these flame holes 550 are arranged so as to be vertically displaced, it is possible to more smoothly divide the combustion exhaust into the upper and lower parts of the grill plate 80. it can. Therefore, even if the heating power of the lower heat burner 55 is weakened, both the upper and lower sides of the object to be cooked placed on the grill plate 80 can be heated in a well-balanced manner. Further, since the left and right lower fire burners 55 each have a slit-shaped flame hole 550, the combustion flame formed in each flame hole 550 can be shortened, and the flame retention property can be improved. Can be done. Therefore, even if the thermal power of the lower heat burner 55 is weakened, stable combustion can be performed with a small combustion flame. Further, since the shortened combustion flame is stably formed in the flame hole 550, fluctuation of the combustion flame due to the lack of secondary air is unlikely to occur even when the grill door 5 is opened, and the combustion flame is moved to the outside of the grill storage 20. Overflow of combustion exhaust can be reduced.

Further, according to the cooking device of the present embodiment, since the lower heat burner 55 is provided on the outside of the left and right side walls 21 and 22 of the grill storage 20, oil and roasted juice can be removed from the cooked object during cooking. Even if they are scattered, they are unlikely to adhere and remain on the lower heat burner 55. As a result, not only the cleanability inside the grill chamber 20 can be remarkably improved, but also ignition failure and combustion failure of the lower fire burner 55 due to the blockage of the flame hole 550 can be prevented. Moreover, since the lower fire burner 55 is provided on the outside of the left and right side walls 21 and 22 of the grill storage 20, and there are few protrusions in the grill storage 20, it is also excellent in cleanability.

Further, according to the cooking device of the present embodiment, by weakening the heating power of the lower heat burner 55, a temperature environment suitable for low temperature cooking can be formed, and the temperature inside the grill plate 80 and the grill storage 20 can be adjusted. Since it is not necessary to repeatedly extinguish the fire of the lower heat burner 55 in order to reduce the temperature, a simple low-cost circuit configuration can be adopted.

(Other embodiments)
(1) In the above embodiment, the lower fire burner 55 is divided into an upper corner portion 555 and a lower corner portion 556 along the inner edge portion 570 of the burner main body 500, and a plurality of slit-shaped flame holes 550 are alternately formed. Have a group. However, as shown in FIGS. 6 and 7, the lower fire burner 55 has the upper corner portion 555 to the lower corner portion between the flame hole 550 group of the upper corner portion 555 and the flame hole 550 group of the lower corner portion 556. It may have a slit-shaped flame holding hole 440 that is long in the vertical direction over 556. According to this, since the combustion flame is also formed in the flame holding holes 440, the fire transfer to each flame holding hole 550 is improved, and the flame holding property is further improved.

(2) In the above embodiment, the lower fire burner 55 has flame holes 550 in the upper corner portion 555 and the lower corner portion 556 of the inner edge portion 570 formed in a substantially U-shaped vertical cross section, respectively. However, as shown in FIG. 8, the inner edge portion 570 is formed in a substantially V-shaped front view cross section so as to taper inward in the left-right direction, and an upwardly inclined surface that inclines diagonally upward and outward. A lower inclined surface 572 that inclines toward 571 and diagonally downward and outward may be provided, and flame holes 550 may be formed in each of these vertically inclined surfaces 571 and 572. According to this, the flame hole 550 formed on the upper inclined surface 571 opens diagonally upward and inward, and the flame hole 550 formed on the downward inclined surface 572 opens diagonally downward and inward. .. Therefore, since the combustion exhaust gas is ejected from the lower heat burner 55 so as to diffuse up and down, the combustion exhaust gas can be smoothly diverted above and below the grill plate 80.

(3) In the above embodiment, the lower fire burner 55 is supported and fixed in a substantially horizontal posture. However, as shown in FIG. 9, the lower heat burner 55 is diagonally upward and inward so that the diversion protrusion 831 provided at the side end 83 of the grill plate 80 is located on the approximate line of the opening of the flame hole 550. It may be tilted toward.

(4) In the above embodiment, a straightening vane 601 extending diagonally upward and outward toward the upper side of the lower fire burner 55 is provided on the upper edge of the openings of the introduction ports 201 and 202. However, as shown in FIG. 9, a straightening vane 602 extending diagonally downward and outward toward the lower side of the lower fire burner 55 may be provided at the lower edge of the openings of the introduction ports 201 and 202.

(5) In the above embodiment, the left and right side end portions 83 of the grill plate 80 are provided with a diversion projection 831 for vertically dividing the combustion exhaust gas. However, a grill plate 80 without a diversion portion may be used. Further, the shape of the flow dividing portion is not particularly limited as long as the combustion exhaust can be divided. For example, the flow dividing portion may be formed in a substantially semicircular shape in a front-view cross section, or may be formed in a plate shape protruding outward from the outer surface 830 of the side end portion 83.

(6) In the above embodiment, the grill plate 80 is formed in a substantially flat plate shape.
