Abstract

A gas-fired stove mainly relates to a gas-fired stove used for restaurants and hotels. The utility model comprises a stove body; a stove core and a combustion area are arranged inside the stove body; a baffle plate is arranged at the exit of the combustion area; support points are arranged on the baffle plate. The stove has the advantages that the stove avoids heat loss when the flame contacts the external cold air in the combustion and heating process; besides, the stove greatly reduces heat loss when the heat is transferred to the external through the high-temperature internal wall, improves the temperature inside the stove and increases the heat transfer efficiency when the gas-fired stove transfers heat to the pot during work. The stove further improves the work efficiency of gas-fired stoves and achieves the energy-saving purpose, big fire power and compact structure.

Description

A kind of gas-cooker

Technical field

The utility model relates to a kind of gas-cooker, relates to the gas-cooker of a kind of restaurant, hotel's use more specifically.

Background technology

Kitchen range is fried in the combustion gas that use in present various restaurant, and great majority exist the problem that heat waste is big, firepower is little for flame in the burning heating process has the non-isolated stir-fry kitchen range that contacts with extraneous; Though and the flame of some large-scale desk-top kitchen range when having used refractory materials such as refractory brick to work is isolated from the outside, but, because refractory materials such as refractory brick still have very big heat conductivity, be difficult to reduce the thermal loss of this part equally, and because of having used refractory materials such as refractory brick, make that stove is heavy, structure is bigger than normal, cause many inconvenience.

The utility model content

Technical problem to be solved in the utility model is, a kind of gas-cooker is provided, and the heat-energy losses in the time of can realizing burning is less, reaches than the higher efficiency of heating surface.

The utility model solve the technical problem the technical scheme that is adopted, and comprises stove, is provided with combustion chamber and combustion zone in the described stove, and exit, described combustion zone is provided with baffle plate, and described baffle plate is provided with the strong point.

The shape of described baffle plate adapts with pot, promptly can be round table-like, perhaps has camber line on round table-like basis, or the like.

Described stove comprises inner and outer wall, and cavity is arranged between the inner and outer wall.

Further, described cavity is formed by baffle plate, inwall, outer wall and base.Described combustion zone exit width W is provided with spacer block less than 3/4ths of round platform exit width W1 in the described combustion chamber, and described spacer block top is the combustion zone, and the inwall of described combustion chamber and the space between the spacer block form blast tube.

The height H of described combustion zone is 7cm～30cm, and the exit width W of combustion zone is 8cm～30cm, and entrance width W2 is 5cm～30cm, and the height W3 of the described strong point is less than 5cm.

Further, be vacuum in the described cavity.Described inner wall surface be smooth surface and surface for blackness less than 0.7 material.

Further, the gas outlet on the combustion chamber is for being oppositely arranged.

The beneficial effects of the utility model are, gas-cooker of the present utility model, avoided flame in the burning heating process with this part thermal loss that contacts of cool ambient air; In addition, because the utility model reasonable in design, between inwall and outer wall, be provided with cavity, and choose rational size, significantly reduced the thermal loss that heat conducts heat to the external world by the high temperature inwall, improved temperature in the stove simultaneously, the efficient that gas-cooker transmits to frying pan heat when having increased work.Add and use above-mentioned premixed combustion chamber, make the fuel can quicker, sufficient burning, thereby further improved the operating efficiency of gas-cooker, reached the purpose of energy-conservation, big firepower, compact conformation.

The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.

Fig. 3 is the utility model embodiment 3 structural representations.

The specific embodiment

As shown in Figure 1, the utility model gas-cooker, mainly comprise stove 1, in stove 1, be provided with combustion chamber 4 and combustion zone 2, the air inlet 42 of described combustion chamber 4 directly is connected with intake stack with the admission line of outside, and described combustion chamber 4 inside are provided with spacer block 44, and the below of spacer block 44 is provided with downward tapered protrusion thing 43, space between the inwall of combustion chamber and the spacer block 44 forms the blast tube 45 that mist leads to combustion zone 2 by the premixer, and the center line of this blast tube 45 is slick and sly curve.The top of described spacer block 44 is combustion zone 2, described combustion zone 2 is cylindric, for combustion gas can be fully burned in combustion zone 2, the scope of the height H of its cylinder is traditionally arranged to be 7cm～30cm, preferred heights is 10cm, and in order to improve the efficiency of heating surface better, the outlet of described combustion zone 2 is connected with baffle plate 11, described baffle plate is round table-like, and the exit width W of combustion zone 2 is less than 3/4ths of the exit width W1 of round platform.Also be provided with the strong point 6 on the described baffle plate 11, be used for placing pot body itself, its purpose is, when the pot body is positioned on the strong point 6, just formed a heat transfer path 3 between its bottom of a pan and the curved surface round platform to scattering all around, among the utility model embodiment, the described strong point is a boss, evenly is provided with 4 boss respectively on baffle plate, brings into play its effect better in order to make heat transfer path 3, the height W3 of described boss 6 (being the width of heat transfer path 3) is generally less than 5cm, preferable width is 1cm, and the width W scope of combustion zone 2 is traditionally arranged to be 8cm～30cm, and embodiment 1, its preferable width is 10cm, as shown in Figure 1; Described combustion zone also can be set to round platform, and as embodiment 2, as shown in Figure 2, the scope of its exit width W is set to 8cm～30cm, and preferable width is 15cm.The scope of entrance width W2 is 5cm～30cm, and preferable width is 10cm.

In order further to reduce the loss of energy, improve the temperature of burning, described baffle plate 11, inwall 13, outer wall 12 and base form cavity.As shown in Figure 2, perhaps, as embodiment 3, as shown in Figure 3, directly by forming between inwall 13, outer wall 12 and the base, described baffle plate is arranged on the outlet edge of combustion zone separately to cavity, and its cavity inside is a vacuum, and the cavity inner surface is set to smooth surface, and the surface is the blackness materials with smaller, is preferably blackness less than 0.7, for example aluminium, copper or the stainless steel etc. through polishing, reduce the energy loss of combustion gas in combustion process with this, improve ignition temperature to greatest extent.Like this, not only make combustion gas in whole combustion process, avoid having improved efficiency of combustion, saved the energy with contacting of cool ambient air.

Gas outlet on the combustion chamber 4 of the present utility model is for being oppositely arranged, that is, the airflow direction that enters the combustion zone from the gas outlet is relative, and with the effect that realizes that air-flow slows down, air-flow can be to come out from the different piece of gas outlet, also can be to come out from different gas outlets.
