Description

Family hot-air warm stove

The utility model belongs to the heating of a kind of room and uses stove, is that the heat of a kind of nationality body of heater and chimney produces the stove of hot blast for the locellus heating.

The common domestic heating stove of holding concurrently and can on stove, heat up water, cook, the heat of body of heater and chimney is mainly supplied with its set kitchen in the mode of radiation, and can not be made full use of; For improving heating efficient, adopt the way of lengthening smoke evacuation chimney usually, but this can strengthen flue resistance, makes smoke evacuation not smooth, so be difficult to the locellus heating.What make improvements in this respect has a coiled indigenous heating stove, two kinds of its branch water heating type and steam heating types, adopt stove fire to burn the hot coil pipe that is located in the burner hearth and come heat(ing) coil interior water or air, carry for the locellus heating with pipeline again, its shortcoming is: after adding coil pipe in the burner hearth, the consumption coal increases, and will set up the longer pipe road, installs time-consuming; Water heating type also to set up radiator, expense is more, installation requirement is also higher; Steam heating type is to introduce outdoor cold air with pipeline to send between calefactory through pipeline after the coil pipe heating again, though structure is slightly simpler than the former, because of the burner hearth of general warming stove is little, coil pipe is difficult to the pipe that uses cross-sectional area bigger, the little flow resistance of caliber is big, and the hot blast output quantity is just few; For accelerating the inner air tube convection velocity, introduce outdoor cold air and heat, empty again gain of heat consumption." Beijing science and technology newspaper " 439 phases propose additional one section heat-exchange tube in the chimney of common domestic heating stove, its two ends are passed the chimney tube wall and are led to indoor, can utilize the useless fume afterheat of the smoke evacuation interlayer of flowing through between heat-exchange tube and chimney, air in the heating heat-exchange tube, make with indoor air convection and improve room temperature, its shortcoming is: only utilize useless fume afterheat, heat is little, is not enough to for the locellus heating; For add heat-exchange tube in chimney, chimney needs special, and is difficult to remove the cigarette ash that gathers in its interlayer; Chimney tube wall and heat-exchange tube are corroded by useless flue gas simultaneously, as long as one of them is etched out aperture, scrap with regard to whole, thereby use inconvenience, and the life-span is short.

The purpose of this utility model is to provide the above-mentioned various warming stoves of a kind of elimination in heating mode and structural shortcoming, keeping common domestic heating stove installs, use easy advantage, still adopt common chimney, and long pipeline need be set, the waste heat that makes full use of body of heater and chimney directly adds hot-air to other chamber heat air delivery, and it is dual-purpose to have a stove, the hot blast domestic heating stove of locellus heating performance.

For achieving the above object, the utility model is achieved in that and mainly contains by shaft, inner furnace body that uptake tube, furnace bottom, fire grate are formed and add upper furnace base and other associate members constitute hot blast domestic heating stove jointly in outside sheathed this two major part of a hot air apparatus of shaft, uptake tube and chimney.The structure of its hot air apparatus is: the fan housing that communicates with the wind trunnion that is provided with a sealing in the shaft outside, at the outside of uptake tube and chimney correspondence be nested with and pegging graft successively wind trunnion and air duct and air-out trunnion, thereby form interlayer between the inside and outside with certain space; Rear side and side at fan housing have air inlet and shutter, are plugged with diffusion barrel on the air-out trunnion, both and indoor communicating.Room air is incorporated into above-mentioned mezzanine space from air inlet and shutter, by shaft and chimney conduction and radiation heating, air after the heating forms hot blast by convection action, carries to the need heating room by air-out trunnion and diffusion barrel, and so constantly circulation reaches the locellus heating.

A lateral partitions can be established in middle part in fan housing, and the air that enters mezzanine space between shaft and fan housing is risen along the shaft revolution, adds thermal effect with raising.

When needs improve the temperature rise speed of heating room room temperature, the household small-size air blast can be inserted air inlet, and close shutter, force air-supply; Also can adopt that the grafting section of a pipe leads to heating room on air inlet, make the air that enters hot air apparatus form closed cycle and improve room temperature.

For making the hot blast warming stove more convenient in the use, can establish fire door to be opened/closed at stove seat header board, back plate at the stove seat is established blast orifice, below the stove seat, establish grey slag bucket, when the needs very hot oven, can close fire door the household small-size air blast is inserted blast orifice to the burner hearth air blast, then worn-out at ordinary times blow-on door natural air inlet, and can utilize fire door to regulate combustion position.The ash slag bucket both can play the effect of closed furnace seat end opening to the burner hearth air blast time, also be convenient to the deashing slag at ordinary times, and unlikely ashes fly upward.

The utility model makes full use of the waste heat of body of heater and chimney, does not increase coal consumption and also can send air heating to other rooms slowly without other power, not only energy savings but also keep the succinct health in room.It does not need to add pipeline and radiator, thereby expense is few, installs easily.General chimney is used in smoke evacuation, and cleaning cigarette ash and change chimney and all easily go has kept that the domestic heating furnace structure is simple now, holds concurrently when cooking a meal kitchen range advantage easy to use, thereby is convenient to promote.

Inner furnace body sizableness of the present utility model in, during small size general domestic heating stove, the air heating room area of its output can reach 20 to 40 square metres and the general residential level of China and adapt.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
