Background technology

As everyone knows, a kind of like this gas furnace was arranged in the past, it has the gas burner that constitutes in the following manner, promptly, this gas burner has: make its downstream end towards the burner that sets out in the panel upper shed with the mixing tube of opening and to be exposed to the burner body on the panel with the diameter of opening greater than burner, make the inflow of the outstanding following central portion that is arranged on burner body be embedded in the downstream end of mixing tube, so that gaseous mixture is supplied in burner body from mixing tube with tube portion.

In addition, dispose the occasion that this gas furnace constitutes built-in stove in the mode in the table top that drops into kitchen system under, air can't be supplied in the stove body around stove body fully.Thus, as everyone knows, gas furnace in the past is formed with ventilating part again on panel, import in the stove body (it is shown in Figure 10 that reference example such as spy open the 2003-148735 communique) with lower surface and gap panel between of primary air via burner body in order to burning.In this gas furnace, relative with the lower surface of burner body to the part of panel on form open-work, constitute ventilating part by open-work.In addition, so that burning forms ventilating part with the mode that primary air imports in the stove body via the lower surface of burner body and the gap between the panel, be to drop in the stove body by ventilating part in order to prevent to boil the soup juice that overflows.

In addition, the said burner main body is by mixing tube and through flowing into tube portion and supported.Yet, flow into the downstream end that closely is embedded in mixing tube with tube portion in order to make burner body dismounting easily, can not to make, will cause burner body to tilt easily like this.This occasion can consider to be connected in the lower surface setting of burner body the projection of panel, in order to stop the inclination of burner body.But, like this, as with the inflow of the chimeric chimeric surface of mixing tube outer peripheral face with tube portion, its machining will be subjected to the obstruction of projection and the trouble that becomes, and when the casting burner body, projection is if still be in the words of the unchanged state of its cast(ing) surface, then can not get the precision on the height of projection, therefore, be necessary to carry out the machining of projection, thereby cause production efficiency to reduce.

Summary of the invention

The present invention in view of the above-mentioned problems, burning can be supplied with in the stove body via the lower surface of burner body and the gap between the panel with primary air to provide a kind of, and the while does not impair production efficiency and can prevent that again the gas furnace of inclination of burner body is as its problem.

For solving above-mentioned purpose, the present invention is the gas furnace with gas burner, this gas burner constitutes in the following manner, promptly, it has: make downstream end towards the burner that sets out in the panel upper shed that covers the stove body upper surface with the mixing tube of opening and to be exposed to the burner body on the panel with the diameter of opening greater than burner, make the inflow of the outstanding following central portion that is arranged on burner body be embedded in the downstream end of mixing tube, so that gaseous mixture is supplied in burner body from mixing tube with tube portion; On panel, be formed with ventilating part, in order to will burn with primary air via the lower surface of burner body and the gap between the panel and import in the stove body; It is characterized in that,, be provided with a plurality of juts, and this jut is connected to the lower surface of burner body, to stop the inclination of burner body towards the top there to be spaced mode in a circumferential direction in the burner of panel opening edge portion with opening; Constitute described ventilating part by the interval between these juts.

According to the present invention, the burner by being arranged on panel limits the inclination of burner body with the jut of the opening edge portion of opening.Thus, there is no need in the outstanding projection that tilts to prevent usefulness that is provided with of the lower surface of burner body, can not be subjected to the obstruction of projection like this and easily carry out the machining of the inflow of burner body with the outer peripheral face of tube portion, in addition, the machining of the projection in the time of also needn't carrying out below burner body, being provided with the occasion of projection after the necessary casting, thus production efficiency improved.And, owing to be burn with in the primary air importing stove body from the lower surface of burner body and the gap between the panel and via the ventilating part that constitutes by the interval between the jut, therefore, even in the time of under occasions such as flush type gas furnace, air can't being supplied to situation in the stove body around the stove body fully, can not produce because of the bad problem of the not enough caused burning of primary air yet.

In addition, in that its diameter that opening sets out constitutes panel greater than the panel body of the peristome of burner body and the juice tray that is installed on this peristome by having the configuration portion that is matched with burner body, and when the upper shed of juice tray sets out the occasion of burner usefulness opening, drop in the stove body with opening from burner in order to prevent to boil the soup juice that overflows, preferably, form the plunging portion that bends to the top in the opening edge portion of burner with opening.And, extend out each jut that stretches to the top integratedly if be, the problem that then can help avoiding the cost that formation brought because of jut to improve from the upper end of this plunging portion.

In addition, generally speaking, can consider to form each jut in the mode of the lower surface that is connected to burner body always.But, like this, because the position of related features on the above-below direction between the downstream end of mixing tube and each jut, before inflow is embedded in the downstream end of mixing tube fully with tube portion, jut has been connected to the lower surface of burner body, so then might can't make to flow into the downstream end that further is embedded in mixing tube with tube portion again.In order to address this problem, preferably make under the state that flows into the downstream end that is embedded in mixing tube with tube portion, the mode of vacating predetermined gap between the upper end with the lower surface of burner body and each jut forms each jut.In addition, this gap is that the mode that the upper end of jut can abut to its lower surface when being a little at burner body and tilting is set.
