Abstract
The invention relates to an auxiliary convection heat-accumulating type heater. The heater comprises a shell and at least one heat-accumulating device capable of storing and releasing heat energy, wherein the upper part of the shell is provided with a gas outlet, the lower part is provided with a gas inlet, the heat-accumulating device is arranged in the shell, and an air gap between the inner surface of the shell and the heat-accumulating device and the gas outlet and gas inlet of the shell constitute a convection channel. The invention is characterized in that the inside of the shell is also provided with an auxiliary convection heating element which releases heat energy to achieve the aim of accelerating the air convection in the convection channel and the convection of room air. The heater can be energized to generate heat energy in a low valley of an electricity grid and release the heat energy in a high valley of the electricity grid for heating room air; when the heat output ofthe heat-accumulating device is insufficient, the auxiliary convection heating element provides complementary convection heat energy by using little power, thus the indoor heating temperature can be more balanced; and the convection gas generated by auxiliary heating performs heat exchange, thus the residual heat energy in the heat-accumulating device can be brought out faster.

Technical field
The present invention relates to storage heater, relate in particular to for indoor a kind of auxiliary convection heat-accumulating type heater.
Background technology
At present, storage heater has obtained application more and more widely.Chinese patent CN201302219Y discloses a kind of automatic convection type powder heat accumulation electric heater, comprise shell, electrothermal tube and accumulation of heat powder, be provided with diaphragm plate up and down in the described housing, described accumulation of heat powder is filled in the described space between the diaphragm plate up and down, the heating part of described electrothermal tube is positioned at and is inserted in described accumulation of heat powder, described case top is provided with shutter, the bottom is provided with down shutter, the described diaphragm plate of going up is with leaving the space that constitutes collection chamber between the described case top, described diaphragm plate down is connected with the some wireways that are communicated with described collection chamber and all press the chamber with leaving the space that formation is all pressed the chamber between the described shell body bottom shell on the described diaphragm plate up and down.This accumulated electric heater is simple in structure, and is easy to use, and heat storage capacity is strong, can electricity consumption and heating time be set flexibly according to actual conditions, can avoid peak of power consumption.But the heat storage of this electric heater is along with the reduction of self temperature, the speed of its release heat can slow down, and can cause the supply shortage of heat to cause indoor temperature to descend gradually like this, influences heating effect, simultaneously heat storage also can residual a large amount of heat in the heat release cycle, causes the waste of the energy.In order to guarantee indoor temperature, producer tends to increase the use amount of heat-storing material, but can make the weight of accumulated electric heater increase like this, increases production cost, and heat storage has more heat to discharge, and disagrees with the energy-conservation concept of present promotion; Moreover, heating this stage of end from heating to, it is bigger that indoor variations in temperature also differs, and lacks the design of hommization adjustment, and being difficult to provides a comfortable indoor environment to people.
Chinese patent CN2521527Y discloses a kind of fan control heat accumulating type Electric heater, by the hot air outlet shutter, and heat storage, electrical heating elements, heat-resistant insulation material, gas channel, shell, support, electric fan, horn ring and controller etc. partly constitute; It is characterized in that: heat storage is metal material, rectangular shape, length * wide * height is of a size of (30～2000mm) * (30～2000mm) * (30～2000mm), heat storage is capable of being combined to be installed and used, and the import of gas and outlet all are arranged on the bottom of Electric heater; Gas channel in the heat storage is the enclosed cross passage that is arranged on heat storage inside, and the equivalent diameter of passage is 5～500mm; Electrical heating elements is vertically mounted on heat storage inside; The import of gas and outlet all are arranged on the bottom of Electric heater.Though the use of the electric fan of this forced convertion accumulated electric heater can make the release heat energy capability improving of heat storage, but it is with new problem, and the formation of these problems uses electric fan to bring exactly: at first, the electric fan of electric heater is involved in indoor dust or foreign matter in the electric heater easily, make shorten the service life of electric heater, the even more serious short circuit that also may cause the electric heater internal circuit brings potential safety hazard to the user; The second, the use of electric fan directly causes the formation of electric heater noise, for indoor environment great influence is arranged; Moreover the setting of electric fan will cause the complicated of electric heater internal structure design.
Summary of the invention
The objective of the invention is to solve existing in prior technology convection current accumulated electric heater release heat ability not high, can not provide that stable heat is supplied with, the high technical problem of heat-storing material consumption, a kind of auxiliary convection heat-accumulating type heater is provided, the release heat ability improves greatly, stable heat can be provided, save the consumption of heat-storing material, alleviated the weight of machine.
Another object of the present invention is to solve existing in prior technology forced convertion accumulated electric heater and easily indoor dust or foreign matter is involved in electric heater inside, forms the technical problem of noise, complex structure etc. easily, a kind of auxiliary convection heat-accumulating type heater is provided, effectively avoided dust or foreign matter to be involved in the problem that electric heater is inner and produce noise, and that structure is simple relatively, quality is compared the forced convertion accumulated electric heater is less.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: it comprises that shell and at least one store and can discharge the regenerative apparatus of heat energy, described shell top is provided with the gas outlet, the shell below is provided with air inlet, described regenerative apparatus setting in the enclosure, the air gap between described inner surface of outer cover and the regenerative apparatus and the gas outlet of shell, air inlet form convection channel, it is characterized in that, also be provided with in the described shell by discharging heat energy and reach the auxiliary Convective Heating element that accelerates air and indoor air convection purpose in the convection channel.Convection channel between regenerative apparatus and housing arranges auxiliary electric heater unit, when indoor temperature is lower than certain value, auxiliary electric heater unit starts automatically, the temperature difference of the hot air temperature in the convection channel and indoor cold air temperature becomes big at this moment, make the convection current of cold and hot air strengthen, before comparing the auxiliary electric heater unit startup, the quantity of hot air that the intake of housing air inlet and housing air outlet are discharged also increases, be that the interior air velocity of convection channel accelerates, this change of air velocity in the convection channel causes the heat exchange on regenerative apparatus surface more violent, the ability of regenerative apparatus release heat is promoted greatly, indoor temperature is also improved accordingly, makes indoor heating temperature more balanced.
