Abstract

A stove energy-saving cover adopting a far infrared ceramic material is made into a truncated cone-shaped cover. The stove energy-saving cover is characterized in that the cover has an uneven surface.

Description

A kind of stove and accessory energy-saving cover

Technical field

The utility model relates to a kind of annex of gas furnace, refers to that specifically a kind of ring puts the energy-saving cover at stove and accessory intermediate combustion position.

Background technology

The heating principle of tradition stove and accessory is come at the bottom of the heating kettle by the direct combustion gas of atmosphere.Such mode of heating, though also can reach the purpose of food in the heating kettle, owing to be subjected to the restriction of the bottom of a pan area, partial flame is because of being not fully utilized, and the part heat is overflowed by the space between the bottom of a pan and stove and accessory, thereby caused the waste of energy.For this reason, people have designed a kind of infrared ceramic ring, as Chinese patent Granted publication number for " the gas furnace energy-saving ring " of CN2453274Y just disclosed so a kind of device, this energy-saving ring is designed to cylindrical or truncated cone-shaped, it adopts far-infrared ceramic material to make, perhaps select heat-stable ceramic for use, surperficial within it more upward coating far infrared forms.During use, its ring is placed the intermediate combustion position of stove and accessory, so both can be used for keeping out the wind, can stop heat energy to external diffusion again, also can utilize the radiation of far infrared simultaneously, increase the efficiency of combustion of combustion gas, therefore can reach the purpose of Synergistic and energy-saving to a certain extent.But in use find: because the surface design of this energy-saving ring becomes smooth type, so the heat radiation area will be subjected to the restriction of energy-saving ring size, and can't under equal conditions remake further raising, thereby still influence the energy-saving effect of stove and accessory.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of surface area big and make the better stove and accessory energy-saving cover of energy-saving effect.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this stove and accessory energy-saving cover adopts far-infrared ceramic material to make the truncated cone-shaped cover body, and it is characterized in that: described cover body inner surface is designed to the roughness structure.

As further improvement of the utility model, can also be densely covered with a plurality of blind holes successively on the described cover body inner surface, perhaps blind hole is made through-hole form, it is convenient to make processing get up.

The diameter of described through hole or blind hole can be chosen in 0.7mm～2.5mm, and area is big like this, and can guarantee the intensity of energy-saving cover again.

As another kind of improvement the of the present utility model, described truncated cone-shaped cover body can be spliced by the polylith far infrared ceramic plate, is convenient to process the truncated cone-shaped cover body like this, and reduces its cost of manufacture.

In above-mentioned each scheme, described roughness structure can also constitute for the bumping square that is distributed in according to certain rules on the described cover body inner surface, and this bumping square can be diamond shaped or oblong-shaped, can certainly adopt cylindric other structure that waits.

Simultaneously, the angle between the lateral surface of described truncated cone-shaped cover body and its bottom surface is to be designed to 25 °～40 ° for good, and the heat energy that helps like this on the energy-saving cover inner surface is radiated on the bottom of a pan.

Compared with prior art, owing to be designed to the roughness structure dexterously on the cover body inner surface of the present utility model, therefore under equal conditions, can increase the internal surface area of cover body widely, the heated surface area and the radiation surface area of this cover body have just been increased, this makes the inner surface of cover body can absorb the flame waste heat exponentially, mode with radiation passes to the bottom of a pan with interest to heat energy again, thereby both realized the dual-heated mode in the bottom of a pan, can improve the thermal efficiency widely again, make maximum energy-conservation can be up to 50%.Also can utilize densely covered through hole or blind hole simultaneously, further improve the heating surface area and the swept area of cover body, improve thermal efficiency of stoves again and make it energy-conservation more obvious, so the utility model value is simple and reasonable for structure, practicality and good energy-conserving effect, and be worth on existing stove and accessory, applying.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment 1: as depicted in figs. 1 and 2, the truncated cone-shaped cover body 1 that this stove and accessory energy-saving cover adopts far-infrared ceramic material to make, the inner surface of this truncated cone-shaped cover body 1 is designed to the roughness structure, here, the roughness structure constitutes for the rhombus projection 11 that is distributed in according to certain rules on the cover body inner surface, simultaneously also be densely covered with a plurality of through holes 12 successively on this cover body inner surface, the diameter of this through hole 12 is 1.5mm, can certainly make 0.7mm or 2.5mm as required.

In the present embodiment, the angle α between the lateral surface of this truncated cone-shaped cover body 1 and its bottom surface is 30 °, also can make 25 ° or 40 °, is convenient to heat like this and is radiated on the bottom of a pan better.

Embodiment 2: as shown in Figure 3, itself and the above-mentioned first embodiment difference are: truncated cone-shaped cover body 1 is spliced by polylith far infrared ceramic plate 2, the surface design of each far infrared ceramic plate 2 becomes the roughness structure, also be densely covered with simultaneously a lot of through holes, help the processing and fabricating of truncated cone-shaped cover body like this.

During use, as shown in Figure 4, above-mentioned energy-saving cover 1 is placed on 4 places, intermediate combustion position of stove and accessory 3, and between energy-saving cover 1 and stove and accessory face, is filled with clay particle 5, utilize each clay particle 5 to block the external port of energy-saving cover through hole 12, prevent that heat from distributing from through hole 12.Like this, the waste heat that is absorbed by the bottom of a pan 6 improves energy-saving cover 1 internal surface temperature rapidly, gives the bottom of a pan 6 thermal energy transfer with radiation mode then, realizes the dual-heated mode in the bottom of a pan with this, and improves energy-saving effect widely.
