In addition, as shown in Figure 3 and Figure 4, framework 21 has: frame upper surface (body side frame top part 21e, afterframe top part 21h), and it covers the ora terminalis on the surface of top board unit 1; Frame facet (body side frame side surface part 21d) and framework rear surface (the afterframe rear surface 21g of portion), they bend below approximate vertical in the end in the outside of frame upper surface, thereby cover the side and the rear surface of top board unit 1; And framework lower surface (body side frame bottom surface sections 21c, afterframe bottom surface sections 21f), it forms to underframe 13 lateral bucklings by the end below frame facet.As Fig. 5 and shown in Figure 9, have a plurality of lug bosses 23 at the framework lower surface.In addition, as shown in Figure 3, in frame upper surface and frame facet,, be formed with the protuberance 29 that is banded protrusion laterally in the mode of be out of shape by stairstepping extruding (section is given as security) from the end in the place ahead 21i preset distance part of about 1～2mm for example.As shown in Figure 3, the end 21i of body side frame 21b is inserted into the inboard of front baffle 22 (front baffle top part 22a and front baffle side surface part 22d), thus end 22h, the 22i at the rear of front baffle 22 (front baffle top part 22a and front baffle side surface part 22d) near protuberance 29 along protuberance 29 configurations.In addition, the details about this protuberance 29 will be explained hereinafter.

In addition; bearer bar 12 also can be roughly framework of コ word shape (not shown) and front baffle 22 formations by observing from the top; the described observation from the top is roughly the framework of コ word shape and afterframe 21a do not cut apart, but formed by the body side frame 21b and the afterframe 21a of both sides.When like this body side frame 21b and afterframe 21a being formed as one, can further improve aesthetics.In addition, bearer bar 12 also can be made of body side frame 21b and these four frameworks of afterframe 21a of front baffle 22, both sides.In addition, in the present embodiment, adopt the cross section to describe, be L word shape roughly but also can be that the cross section is local or whole for the framework 21 of コ word shape roughly.

Next, Fig. 6 represent from beneath to the stereogram of top board unit 1, Fig. 7 represents view of apparatus around the forward corner 19 on the left side in the front baffle 22 of Fig. 6.In addition, Fig. 8 represents that with the cutaway view of front baffle shown in Figure 6 22 along the incision of A-A line Fig. 9 represents the cutaway view along the incision of B-B line with body side frame 21b, and Figure 10 represents the cutaway view along the incision of C-C line with afterframe 21a.

As mentioned above, body side frame 21b has a plurality of lug bosses 23 at body side frame bottom surface sections 21c.Among former frame frame 22 and the body side frame 21b, as Fig. 8 and shown in Figure 9, former frame frame the place ahead bottom surface sections 22e and body side frame bottom surface sections 21c are provided with lug boss 23 by cutting out to erect respectively.The quilt of the lug boss 23 of She Zhiing cuts out the inner surface butt of the end face that erects and the fastening hole 13a (with reference to Fig. 4) of the ora terminalis that is arranged at underframe 13 like this, thus front baffle 22 and body side frame 21b in the mode that can not break away from from underframe 13 by fastening, thereby front baffle 22 and body side frame 21b are fixed in underframe 13.Thus, the mode with the ora terminalis of while double team top board 11 and underframe 13 covers this two ora terminalis between the front baffle 22 former frame top of support 22a of portion and the front baffle the place ahead bottom surface sections 22e.And body side frame 21b mode with the ora terminalis of while double team top board 11 and underframe 13 between body side frame top part 21e and body side frame bottom surface sections 21c covers this two ora terminalis.

As Fig. 4～shown in Figure 9, underframe 13 has peristome 13d, and is formed with: two banded mounting surface 13i, and it is arranged at the periphery upper surface of peristome 13d; And bonding plane 13j, it has a ladder with respect to mounting surface 13i between mounting surface 13 poor, and the height of this bonding plane 13j is lower.During in mounting surface 13i, utilizing crooked to vertical direction and the tray side 13b as keeper that form top board 11 mountings, the position of the side of this top board 11 is being limited with respect to mounting surface 13i.Top board 11 by mounting under the state of mounting surface 13i, bonding agent 31 is spreaded all over peristome 13d complete cycle coat bonding plane 13j.Thus, the lower surface bonds of underframe 13 and top board 11, thereby keep top board 11, and mounting be disposed at top board 11 the rear rear portion cover 14 and fix.

As shown in Figure 2, will cover the screw thread that 14 sides run through from the rear portion via hole 14e and be fixed to three fixing hole 13g that are arranged at underframe 13, thus, rear portion cover 14 is fixed in underframe 13.With top board unit 1 mounting that constitutes like this in the 2Cb of horizontal flanges portion (with reference to Figure 10) that is formed on body shell 2C upper end, to and be arranged at the screw thread that runs through three hole 13h (with reference to Fig. 2 and Fig. 6) of underframe 13 from three hole 14d being arranged at rear portion cover 14 and be fixed to the fixing hole (not shown) that is arranged at described flange part, thus, the rear part of top board unit 1 is installed in body shell 2C.

In addition, as shown in Figure 6, on underframe 13, the part in the place ahead of the periphery that is positioned at formed peristome 13d is provided with an engagement device 13e, and is provided with engagement device 13f in the both sides of engagement device 13e.By engagement device 13e and engagement device 13f screw thread are fixed to body shell 2C, top board unit 1 is fixed in body shell 2C.

In addition, be provided with the fastening hole 13a of a plurality of rectangles at underframe 13, the lug boss 25 that is arranged at framework 21 and front baffle 22 described later is inserted among the fastening hole 13a of these a plurality of rectangles.In addition, be provided with a plurality of screwed hole 13c that are used for fixing front baffle 22 at underframe 13.

Herein, Figure 11 represent from beneath to the stereogram of front baffle 22.As Fig. 3, Fig. 7 and shown in Figure 8, former frame frame 22 is formed with: the front baffle front surface 22c of portion, and its 22g place, end by the place ahead of the former frame top of support 22a of portion bends and forms; Front baffle side surface part 22d, its place, end, side by the former frame top of support 22a of portion bends and forms; Front baffle the place ahead bottom surface sections 22e, it is the part that the lower end of the former frame frame front surface 22c of portion forms to underframe 13 lateral bucklings; And front baffle side bottom surface sections 22f, it is the part that the lower end of former frame frame side surface part 22d forms to underframe 13 lateral bucklings, front baffle 22 forms roughly bag shape on the whole.In addition, former frame frame the place ahead bottom surface sections 22e is formed with a plurality of installing holes 24 and lug boss 25.In addition, as Fig. 4 and shown in Figure 6, front baffle the place ahead bottom surface sections 22e has the covering portion 26 of the roughly trapezoidal shape that protrudes to the inboard of top board unit 1 near the end of side.

Front baffle side bottom surface sections 22f and front baffle the place ahead bottom surface sections 22e that the place, end of the below of former frame frame side surface part 22d forms to top board 11 lateral bucklings form roughly same plane, and adjacent near the bight 19 of bearer bar 12.In addition, the end of former frame frame the place ahead bottom surface sections 22e is formed with the covering portion 26 of protruding to the inboard of top board 11.In the present embodiment, covering portion 26 is formed near the both ends of front baffle the place ahead bottom surface sections 22e, and is formed near the end of front baffle side bottom surface sections 22f.That is, also can make the width of the width of front baffle side bottom surface sections 22f greater than front baffle the place ahead bottom surface sections 22e.In addition; the shape of covering portion 26 is not limited to shape shown in Figure 11; so long as protrude to the inside and can make front baffle the place ahead bottom surface sections 22e and the front baffle side bottom surface sections 22f adjacent part shape bigger mutually, then can be arbitrary shape than the situation that covering portion 26 is not set near the mode at the back side the forward corner 19 of covering protection frame 12.

In addition, as shown in Figure 3 and Figure 4, at the lateral surface of body side frame 21b, be as described above banded ground laterally the protuberance 29 that protrudes of direction be arranged near the 21i of side end nearby of body side frame 21b lateral surface in mode along end 22h, the 22i at the rear of front baffle 22.Protuberance 29 forms along lateral surface respectively near the end 21i in the place ahead of left and right sides framework 21b.Protuberance 29 is by making cross sectional shape and be deformed into a roughly oval part or the shapes such as a part of essentially rectangular forming, and the protrusion amount of protuberance 29 (height of heaving) is preferably more than the thickness that constitutes the front baffle 22 that is cooperated.In addition, the protrusion amount of protuberance 29 also can determine according to the thickness of slab and the aeration level of front baffle 22, and described aeration level is meant and is used to gap that front baffle 22 is cooperated with framework 21.

In addition, as shown in Figure 7 and Figure 8, the cross section of front baffle 22 forms roughly コ word shape, and front baffle 22 is installed along the ora terminalis in the place ahead of top board 11.At this moment, the end 21i of body side frame 21b is inserted into the inboard of front baffle side surface part 22d and front baffle top part 22a, and protuberance 29 butts of the end 22h at the rear of front baffle side surface part 22d and front baffle top part 22a and body side frame 21b or adjacent (with reference to Fig. 3 and Fig. 4).Its result is that front baffle 22 covers the end 21i (edge) of body side frame 21b.

On the other hand, end (edge) 22i, the 22h at the rear of front baffle side surface part 22d and front baffle top part 22a and protuberance 29 butts that form along the lateral surface of framework 21 or adjacent.Thus, because protuberance 29 forms with the state that does not have the sharp keen edge as the section projectedly from the surface of body side frame top part 21e and body side frame side surface part 21d as described above, therefore can prevent that cooking person is hindered by end 22i, the 22h (edge) at the rear of the end 21i in the place ahead of body side frame 21b and front baffle side surface part 22d and front baffle top part 22a.The height of the projection of protuberance 29 for example can suitably be set the height of the degree that finger can not hindered by the edge of the end of front baffle 22 for.

In addition, around protuberance 29, because protuberance 29 adopts the material identical with body side frame 21 to form, so protuberance 29 can be very unshowy, has the aesthetic property of excellence.In addition, owing to be that body side frame 21b is inserted into structure in the front baffle 22 of linearity,, has the aesthetic property of excellence so as Fig. 1 or shown in Figure 2, in the part that top board 11 exposes, two bights of cooking person's side constitute approximate right angle.

In addition, as mentioned above, former frame frame the place ahead bottom surface sections 22e is formed with a plurality of installing holes 24 and lug boss 25.Thus, the same with the lug boss 23 that is formed at said frame 21, the lug boss 25 that is formed at front baffle 22 is by being embedded in the hole that is formed at underframe 13, and with front baffle 22 fastenings in underframe.In addition, for example be fixed to underframe 13 by Screw being passed installing hole 24 screw threads, front baffle 22 is fixed.Its result is, can prevent that the bearer bar 12 that is made of framework 21 and front baffle 22 from coming off from underframe 13 because of distortion or distortion etc. make fastening based on lug boss 23 get loose.

In addition, as shown in figure 10, when the peristome of the essentially rectangular of body shell 2C being put into cabinet (cabinet) 1E is assembled, be installed on the back side and the cabinet upper surface 1Eb butt of bearer bar 12 of the flange part 2Cb of body shell 2C.For the liquid that prevents to be sprinkled upon cabinet upper surface 1Eb invades the inboard of bearer bar 12, in the complete cycle scope at the back side of bearer bar 12, further be fixed with for example such elastomeric seal 32 of rubber-like Foamex.Under the situation at the back side of seal 32 being fixed in front baffle the place ahead bottom surface sections 22e; as mentioned above; because the end of the side of former frame frame the place ahead bottom surface sections 22e has the covering portion 26 of protruding to the inside partly; therefore; particularly in bight 19 rear side in the place ahead of bearer bar 12; because seal 32 is arranged between bearer bar 12 and the cabinet; the seal 32 that is arranged at front baffle the place ahead bottom surface sections and front baffle side bottom surface sections is pressed against cabinet by top board unit 1 under non-deflecting state, thereby can play consistently the sealing effectiveness that seal 32 is produced.

As shown in Figure 8, about ora terminalis 30 as the rear of the front baffle top part 22a of the part of the upper surface that constitutes front baffle 22, except the part that the ora terminalis for framework 21 inserts, remainder bends in the mode that further tilts towards top board 11 sides with descending, and the surface of the end of this ora terminalis 30 and top board 11 (face of mounting cooking-vessel) butt.Thus, can stop up the gap that is formed between top board 11 and the front baffle top part 22a.Its result is to prevent that dust etc. from invading in the formed gap.

Like this, bearer bar 12 has omitted the joint component that is formed by other parts at the connecting portion of body side frame 21b and front baffle 22, has reduced the components number that constitutes bearer bar 12, is easy to assembling.In addition, end 22i, the 22h at the rear of front baffle 22 is provided near the protuberance 29 of the upper surface that is formed at body side frame 21b and side, the end 21i in the place ahead of body side frame 21b is covered by front baffle 22, can prevent thus that cooking person from touching the end 21i of the end of front baffle 22 or body side frame 21b and injured.In addition, because the linearity end of the front baffle 22 that constitutes bearer bar 12 and the inboard of body side frame 21b is vertically formed the bight, so the bight that the top board 11 with bearer bar 12 fringings is exposed is approximate right angle.Thus, can improve the aesthetic property of top board 11.

Next, with reference to Fig. 1, Fig. 2, Figure 12, Figure 13 and Figure 14, over cap 15a and the 15b in top board 11 describes to mounting.In the present embodiment, two over cap 15a, 15b about the rear of top board 11 (side opposite of top board 11) with upper surface operating portion 1D side by side mounting on rear portion cover 14.Over cap 15a is positioned in the mode of the top of covering grill exhaust outlet 14a and exhaust outlet 14b, and over cap 15b is positioned in the mode on the top of covering air inlet 14c.

Figure 12 represents the stereogram of mounting in over cap 15b top board unit 1, the right side shown in Figure 1, and Figure 13 represents the cutaway view along the incision of D-D line with the over cap 15b among Figure 12.As shown in Figure 1, the over cap 15b on the over cap 15a in left side and right side is with center line separated equably about the upper surface of top board unit 1 to serve as the plan view shape that axle forms roughly symmetry.

Over cap 15b is for example formed by aluminium diecasting, and as shown in figure 12, over cap 15b has: a plurality of air admission hole 15ba; The 15bb of grid portion as the clathrate part that is formed with a plurality of air inlet 15ba; And as general planar par 15bc partly.In addition, the 15bb of grid portion covers the top of the air inlet 14c be formed at rear portion cover 14, and over cap 15b covers the rear portion cover 14 of air inlet 14c side and the top of the bearer bar 12 that is provided with along the periphery of this part rear portion cover 14 on the whole.

On the other hand; in over cap 15a; similarly; the 15ab of grid portion covers the top of the grill exhaust outlet 14a that is formed at rear portion cover 14 and the top of exhaust outlet 14b, and over cap 15a covers the rear portion cover 14 of grill exhaust outlet 14a and exhaust outlet 14b side and the top of the bearer bar 12 that is provided with along the periphery of this part rear portion cover 14 on the whole.That is, the leading edge of over cap 15a covers the leading edge of rear portion cover 14, and the back edge of over cap 15a covers the back edge of top board unit 1.

Over cap 15a, the 15b of Xing Chenging prevents that foreign matter etc. from falling grill exhaust outlet 14a, exhaust outlet 14b or air inlet 14c like this; and can not damage attractive in appearancely by covering these peristomes, simultaneously the cigarette that produces in the grill (not shown) of the inboard of grill door 3 or smell etc. are expelled to the outside.In addition, par 15ac, the 15bc of over cap 15a, 15b prevented to be attached to the rear portion cover 14 that forms concaveconvex shape as shown in Figure 2 from the unrestrained soup juice of cooking-vessel etc., makes the decontamination operation become easy.

Figure 14 is the summary partial top view that the position of the guide portion 15be of expression over cap 15b and 15bf and over cap mounting portion 16 concerns.As shown in figure 14, be provided with at the back side of over cap 15b (face of 14 sides is covered at the rear portion) that end parts parallel ground with the place ahead of over cap 15b and rear extends, be convex and linearly a plurality of guide portion 15be, 15bf.In addition, in the present embodiment, guide portion 15be and 15bf are formed with two respectively, add up to be formed with four, and described guide portion 15be and the mutual almost parallel of 15bf.

On the other hand, around grill exhaust outlet 14a, the exhaust outlet 14b of rear portion cover 14 and air inlet 14c, as shown in Figure 2, for example be formed with a plurality of (being 4 in the present embodiment) over cap mounting portion 16 by elastomeric materials such as rubber.

Over cap 15b mounting during in top board unit 1, is being formed at the guide portion 15be of over cap 15b and the inboard that 15bf is embedded into over cap mounting portion 16 herein.Thus, over cap 15b is limited to the mobile of direction all around of top board unit 1.Promptly; because the contacts side surfaces of two guide portion 15be of the inboard of over cap 15b also embeds the inboard that is arranged at the over cap mounting portion 16 of fore-and-aft direction with respect to guide portion 15be; so limited the position of the fore-and-aft direction of over cap 15b; because contact of the end of two guide portion 15bf in the outside of over cap 15b and embedding are arranged at the inboard of the over cap mounting portion 16 of left and right directions with respect to guide portion 15bf, so limited the position of the left and right directions of over cap 15b.Like this, in order to limit the position to the direction all around of over cap 15b, as long as guide portion 15be has at least two and guide portion 15bf to have one at least.In addition, also be the same for over cap 15a.

In addition, the end at the rear of over cap 15b and the end of side that is positioned at the outside are to observe from the top and side and the rear surface formation of the roughly consistent mode of the side of the framework 21b of top board unit 1 and rear surface (body side frame side surface part 21b and the afterframe rear surface 21g of portion) along the framework 21b of this top board unit 1.In addition, as shown in Figure 2, the right back bight 15bd of over cap 15b forms with the arc radius littler than the arc radius in right back bight 17 of the top board unit 1 that is positioned at its below.Thus; the right back bight 15bd of over cap 15b constitutes than the right back bight 17 of the top board unit 1 of its below and protrudes; therefore cooking person's lower surface that finger can be withstood the bight 15bd of over cap 15b lifts from the below, thereby easily over cap 15b is unloaded from top board 11.In addition, over cap 15b also can form from the framework 21 of top board unit 1 and lean out to horizontal part or integral body.In addition, also be the same for over cap 15a.

In addition, as shown in Figure 2, the structure of over cap 15a is identical with over cap 15b.As long as constituting than the left back bight 18 of the top board unit 1 of its below, the left back bight 15ad of over cap 15a protrudes.In addition, over cap 15a and 15b bight 15ad and 15bd separately also can form approximate right angle respectively.Thus, over cap 15a and 15b bight 15ad and 15bd separately can constitute than the bight 17 of top board unit 1 and 18 and protrude.

Like this; since over cap 15a and 15b constitute will be arranged at grill exhaust outlet 14a, exhaust outlet 14b, the air inlet 14c of top board unit 1 and comprise the top board bight around cover, can prevent that therefore pollutant or unrestrained soup juice etc. are attached to around the exhaust outlet.In addition, can be easily the pollution that oil smoke caused on the top of grill exhaust outlet 14a be cleaned.

In addition, because over cap 15a and 15b bight 15ad and 15bd separately form with the little arc radius of arc radius than the bight of top board unit 1, so the bight of over cap 15a, 15b forms from the bight of top board unit 1 and protrudes.Thus, cooking person can pick up over cap 15a and 15b in the part of this protrusion, can dismantle over cap simply.Its result is, very simply just can only clean over cap 15a and 15b.
