Abstract

The utility model provides a domestic heating stove. A circular flue is arranged at the outside of a hearth of the domestic heating stove. A moving heat insulating board is arranged in a smoke return cavity. A grate is divided into an upper and a lower layers, wherein, the upper layer is a water pipe communicated with the circulating water of the domestic heating stove. The domestic heating stove has full heat utilization, and is suitable for heating and cooking for families in 'Three North ' areas.

Description

Domestic heating stove

The utility model relates to a kind of coal heating equipment, a kind of specifically domestic heating stove.

China three northern areas of China cold in winter needs heating system in the man.Great majority are not carried out in the resident family of collective's heating, all need own to adorning native heating installation.But all there is the not high problem of heat energy utilization rate in most domestic heating stoves.

The purpose of this utility model is that the domestic heating stove that provides a kind of thermal efficiency high is provided.

The technical solution of the utility model is as follows: a side outlet flue and an annular flue that communicates with chimney are arranged in the burner hearth outside of furnace; In returning the cigarette thorax, a portable boiler face warming plate is arranged; When warming plate was covered in outlet flue, all flue gases just entered annular flue through the side outlet flue, and when removing warming plate, flue gas has two paths: 1, burner hearth → last outlet flue → chimney.2, burner hearth → side outlet flue → annular flue chimney.

This furnace has double-layer grate, and upper grate is the water pipe that links to each other with furnace recirculated water, and lower floor is the cylinder steel bar.

The utility model has been owing to increased annular flue, boiler face warming plate, and the water pipe furnace grate that links to each other with furnace recirculated water, thus more abundant to heat energy utilization, than existing household central heating furnace thermal efficiency height.

Below in conjunction with accompanying drawing the utility model is further explained:

Embodiment 1: as can be known, these family expenses furnace is made up of chimney [1], stone or metal plate for standing a stove on as a precaution against fire [3], burner hearth [10], time cigarette thorax [11], fire grate [5,6], grey thorax [12] from Fig. 1 and Fig. 2.Outside in burner hearth [10], the offside of chimney [1] has a side outlet flue [9] and a side coal filling hole [13], also have an annular flue [4] that communicates with chimney [1] and side outlet flue [9], in returning cigarette thorax [11], a portable warming plate [2] that is covered in outlet flue, coal filling hole [8] is arranged; Fire grate is double-deck, is dislocation arrangement, and upper grate is the water pipe that links to each other with furnace recirculated water, and lower floor is the cylinder steel bar.Have one deck that flue is divided into inside and outside two-layer dividing plate [16] in the middle of the annular flue [4], inner flue all communicates with side outlet flue [9], chimney with external flue.Warming plate [2] all has refractory insulating layer with side coal filling hole [13] lid.

Embodiment 2: from Fig. 3 and Fig. 4 as can be known, in burner hearth [10] one sides a side outlet flue [9] is arranged as different from Example 1 near chimney [1], annular flue [4] is divided into inside and outside two-layer by dividing plate [16], the internal layer flue communicates with side outlet flue [9], and outer flue communicates with chimney [1].The ectonexine flue is located to communicate at the side coal filling hole [13] of the offside of side outlet flue [9].

Embodiment 3: from Fig. 5,6 as can be known, with embodiment [1], different is, side outlet flue [9] is positioned at burner hearth [10] one sides near chimney [1], annular chimney [4] is divided into upper and lower two-layer by dividing plate [16], lower floor's flue communicates with side outlet flue [9], and the upper strata flue communicates with chimney [1], and upper and lower layer flue located to communicate in the side coal filling hole [13] of the offside of side outlet flue [9].

Embodiment 4: as can be seen from Figure 7, as different from Example 1, side outlet flue [9] is positioned at the side near the burner hearth [10] of chimney [1], and side outlet flue [9] has a dividing plate [16] that makes annular flue [4] can only have a mouth and chimney [1] to communicate with chimney [1] joint.
