Abstract

The utility model provides a firewood-saving and coal-saving stove core, including a stove core, the opening of which is faced to a stove door, and a grate which is arranged at the bottom part of the stove core, wherein, the stove core is composed of an outer core and an inner core which is arranged at the inside of the outer core and is provided with an oxygen supply hole; the utility model is characterized in that the lower end of the horseshoe-shaped outer core is fixed on a rectangular bottom board, the middle part of the bottom board is provided with a horseshoe-shaped through hole, a block is arranged at the hole edge of the through hole at certain interval, the lower end of the horseshoe-shaped inner core is arranged on the block, the upper end of the horseshoe-shaped inner core is provided with an annular-edge tray, the annular-edge tray is arranged at the upper end of the outer core, the upper surface of the annular-edge tray is an upward slope, and the horseshoe-shaped grate is arranged on the block which is arranged at the bottom part of the inner core. The utility model is not only characterized by the small space of a stove chamber of the horseshoe-shaped stove core, firewood-saving and coal-saving, but also can provide the combustion-supporting oxygen to the stove chamber, which can save more firewood and coal; at the same time, the utility model can enable the combustion heat energy not only to be concentrated at the pot bottom, but also to be concentrated at the pot body, so as to effectively improve the thermal utilization ratio; when in use, the utility model is more convenient to add firewood, coal and clean the ash, which is very applicable to the reconstruction of the current existing firewood-fired and coal-fired stoves, so as to save the resources.

Description

A kind of firewood-saving and coal-saving kitchen range core

Technical field

The utility model relates to a kind of kitchen range core of Civil energy-saving cooking stove, belongs to coal-fired, fires wood stove kitchen range structural design and manufacturing technology field.

Background technology

Present combustion bavin, the coal fired stove that uses in the rural area, its kitchen range core is the opening the fixed shape of a hoof towards the kitchen range door mostly, kitchen range core below is a fire bars, the fire bars below also is an oxygen supply port for ash hole simultaneously, the kitchen range in-core is combustion bavin, the coal-fired chamber of a kitchen range, and the kitchen range core forms the flue that is communicated with chimney with space between the stove, and the air of its combustion-supporting usefulness can only enter the chamber of a kitchen range below fire bars, not only take bavin, expense coal, and efficiency of combustion is low.Therefore, be necessary fully existing kitchen range core is improved.

Summary of the invention

For overcoming deficiencies such as the consumption bavin, consumption coal and the efficiency of combustion that have combustion bavin, the existence of coal fired stove kitchen range core now are low, the utility model provides a kind of firewood-saving and coal-saving kitchen range core.

The utility model is realized by following technical proposal: a kind of firewood-saving and coal-saving kitchen range core, comprise the kitchen range core of its opening towards the kitchen range door, be positioned at the fire bars of kitchen range core bottom, its medium mess core is by outer core and place the inner core which is provided with the oxygen supply hole of outer in-core side to combine, it is characterized in that horseshoe-shaped outer core lower end is fixed on the rectangular base plate, the middle part of base plate has shape of a hoof through hole, the limit, hole of through hole is interval with block, horseshoe-shaped inner core lower end places on the block, shape of a hoof inner core upper end is provided with the annular edge dish, the annular edge dish places outer core upper end, and the upper surface of annular edge dish is made as inclined plane upwards, and shape of a hoof fire bars places on the block of inner core bottom.

The outside by the kitchen range door on the described base plate is provided with the bar shaped boss, and fire bars places the inboard of this boss, and concordant with boss, so that can add bavin or logical ash smoothly in the chamber of a kitchen range.

Described outer core opening both sides are provided with vertical rib, and this rib docks with the straight flange of inner core opening both sides, thereby make the oxygen supply passage that forms sealing between outer core and the inner core, and the combustion-supporting oxygen of using is provided in the chamber of a kitchen range once more.

The utility model compared with prior art has following advantage and effect: adopt such scheme, the chamber of a kitchen range space that both can keep original shape of a hoof kitchen range core to have is little, the joint bavin, characteristics such as coal, outside can passing through again, interlayer oxygen supply passage between the inner core provides the combustion-supporting oxygen of using once more in the chamber of a kitchen range, make it more to economize coal, economize bavin, the efficiency of combustion height, inclined plane by the inner core upper surface is provided with again, makes combustion heat energy not only concentrate on the bottom of a pan, also concentrates on pot body, effectively improved heat utilization efficiency, when using simultaneously, be more convenient for adding bavin, stoking, logical ash, be very suitable for existing combustion bavin, coal fired stove is transformed, and economizes on resources.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

The outer core 2 of the shape of a hoof is fixed on the base plate 1, shape of a hoof inner core 3 places the inboard of outer core 2, the opening 6 of outer core and inner core is all towards the kitchen range mouth, as Fig. 1, base plate 1 is a rectangular slab, its middle part has shape of a hoof through hole 11, the limit, hole of through hole is interval with block 12, inner core 3 lower ends and shape of a hoof fire bars 4 place on the block 12, the outside by the kitchen range door on the base plate 1 is provided with bar shaped boss 13, this boss is concordant with fire bars 4, as Fig. 2, Fig. 3, Fig. 5, the opening both sides of inner core 3 are provided with straight flange 34, so that in the chamber of a kitchen range, add bavin, coal, inner core 3 tops are provided with 2 row's oxygen supply holes 31, inner core 3 upper ends are provided with annular edge dish 32, the upper surface of annular edge dish is inclined plane 33, be convenient to join with the pot body, and a pot body also is heated, annular edge dish 32 places the upper end of outer core 2, as Fig. 1, Fig. 4, the opening both sides of outer core 2 are provided with vertical inclined flange 21, this rib docks with the straight flange 34 of inner core 3 opening both sides, thereby makes between outer core and the inner core oxygen supply passage 5 that forms sealing, so as from the air of base plate through oxygen supply passage 5, oxygen supply hole 31 enters in the chamber of a kitchen range combustion-supporting.
