Description

A kind of layer of furnace door structure

Technical field

The utility model relates to baking device field more particularly to a kind of layer of furnace door structures.

Background technique

Layer furnace is a kind of food baking equipment mainly heated in the way of heat radiation.In the heating process to food In, furnace heat has part that can be lost to the external world.For fire door, it is excessively high that this has resulted in fire door surface temperature, is easy scald Operator；And partial heat is lost, and power consumption is caused to increase.

In response to this problem, current prioritization scheme are as follows:

(1) heat-preservation cotton is filled up between inside and outside two plate of fire door.Its starting point is the heat transfer heat for reducing fire door, to reach To the purpose for reducing fire door hull-skin temperature.

(2) glass in fire door center is changed to weaken in furnace using double glazing to the fire door external world by original single layer Heat radiation.

But above two scheme has the following problems: due in furnace based on radiant heat transfer, the temperature of fire door inner surface Degree is usually higher, if only reducing hull-skin temperature by filling heat insulating wall, required insulation layer thickness wants thick, otherwise outside fire door The reduction of plate surface temperature is not obvious；In addition, fire door generally requires setting peep hole cannot be used due to visual inspection Filled thermal insulation materials, so that glass surface temperature is very high.

Utility model content

The applicant is directed to above-mentioned existing issue, has carried out Improvement, provides a kind of layer of furnace door structure, which solve The excessively high problem of surface temperature, allows fire door to maintain lower temperature for a long time in fire door use process.

Technical solution used by the utility model is as follows:

A kind of layer of furnace door structure, including spaced outside plate and inner panel are arranged between Yu Suoshu outside plate and inner panel Heat-preservation cotton is arranged between the first air layer of Yu Suoshu and the second air layer, in the heat-preservation cotton in one air layer and the second air layer Periphery wrap up masking foil, muti-piece is also set up at the center of Yu Suoshu outside plate and inner panel in spaced apart glass, each block of glass The outside plate, inner panel, heat-preservation cotton, masking foil, the first air layer and the second air layer are separated to form left and right two parts, in each phase The third air layer for inhibiting fire door thermally conductive is also set up between adjacent glass.

Its further technical solution is:

The outside plate and inner panel are stainless steel plate；

The glass uses high temperature resistant tempered glass；

Gap setting between the heat-preservation cotton and outside plate, inner panel, the heat-preservation cotton and outside plate, inner panel are parallel each other.

The beneficial effects of the utility model are as follows:

The utility model structure is simple, easy to use, good heat-insulation effect, 33 DEG C, layer furnace in-furnace temperature of room temperature setting 200 DEG C when, fire door glass outer surface temperature is about 45 DEG C in 30min, temperature rise about 12 DEG C of (about the 1/8 of single-glass, double glazings 1/3), the fire door surface long period can be maintained reasonable temperature by the utility model, greatly reduce the occurrence of hot.

Thermal insulation property in furnace is also slightly improved, oven heating duration can be shortened by a small margin and extend in furnace to reach setting Soaking time after determining temperature, in addition the utility model can save a little electricity, have certain economic benefit.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Wherein: 1, outside plate；2, inner panel；3, glass；4, heat-preservation cotton；5, masking foil；6, the first air layer；7, the second air Layer；8, third air layer.

Specific embodiment

Illustrate specific embodiment of the present utility model below.

A kind of layer of furnace door structure described in the utility model includes spaced outside plate 1 and inner panel 2, outside plate 1 and interior Plate 2 is stainless steel plate.First air layer 6 and the second air layer 7 are set between outside plate 1 and inner panel 2, in the first air layer 6 And second heat-preservation cotton 4 is arranged between air layer 7, masking foil 5 is wrapped up in the periphery of heat-preservation cotton 4, in the center of outside plate 1 and inner panel 2 Place also sets up muti-piece in spaced apart glass 3, and glass 3 uses high temperature resistant tempered glass.Its spoke for being used to increase fire door glass Thermal resistance is penetrated, outside plate 1, inner panel 2, heat-preservation cotton 4, masking foil 5, the first air layer 6 and the second air layer 7 are separated shape by each block of glass 3 At left and right two parts, the third air layer 8 for inhibiting fire door thermally conductive is also set up between each adjacent glass 3.Heat-preservation cotton 4 and outer Gap setting between plate 1, inner panel 2, heat-preservation cotton 4 and outside plate 1, inner panel 2 are parallel each other, avoid contacting with outside plate 1 and inner panel 2, protect Card increases the radiation thermal resistance of fire door under the premise of certain thermal conduction resistance.

Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape The modification of formula.
