Description

Warmer

Technical field

The present invention relates to a kind of warmer.

Background technology

It is in the majority that common warmer dispels the heat in heat radiation mode, as the patent No. Chinese utility model patent < < energy-saving electric warmer > > (Granted publication number: CN201059678Y) that is ZL200720052171.4, open < < multifunctional electric warmer > > (publication number: CN101509679A) of Chinese invention patent application that and for example application number is 200910119205.0, on this class warmer structure, generally all comprise housing, heater and expelling plate etc., hear rate is larger, and warmer self-temperature is higher, easily scald, also be easy to cause other combustibles burnings around, so be prone to accidents in not attention situation, there is certain potential safety hazard.If need to increase convection effects, blower fan generally need to be set and be blowed, this will certainly increase energy consumption, and blower fan blows the heating that can only reach subregion, poor effect simultaneously.

As improvement, in prior art, there is a kind of warmer, see shown in Fig. 5 and Fig. 6, this warmer comprises radiator 1a and is located at the heater in radiator 1a, radiator 1a has accommodating cavity 11a and a plurality of heat radiation chamber 2a for air convection current from bottom to top and longitudinal setting of a plurality of horizontally sets, heater is horizontally set in accommodating cavity 11a and runs through heat radiation chamber 2a, this kind of warmer utilizes stack effect, greatly improved convection effects, but this warmer exists following not enough: only at top, offer hot air outlet, so top is boiling hotter, careless slightly being easy to scalded; Secondly, because hot air outlet setting is higher, after whole room temperature rises, human body is just experienced heat, so heating is slower, and energy consumption is large.

Summary of the invention

Technical problem to be solved by this invention is that a kind of warmer of scalding human body simple in structure, difficult is provided for the above-mentioned state of the art.

Another technical problem to be solved by this invention is to provide that a kind of energy consumption is low, convection current heats up warmer rapidly.

The present invention solves the problems of the technologies described above adopted technical scheme: a kind of warmer, comprise radiator and be located at the heater in radiator, described radiator has accommodating cavity and a plurality of heat radiation chamber for air convection current from bottom to top and longitudinal setting of at least one horizontally set, described heater is horizontally set in aforesaid accommodating cavity and runs through aforesaid heat radiation chamber, it is characterized in that described heat radiation chamber at least has the first heat radiation chamber and the second heat radiation chamber from bottom to top, accordingly, described heater at least comprises through first heater in the first heat radiation chamber and through second heater in the second heat radiation chamber, aforesaid the first heat radiation chamber has the first air inlet and the first air outlet, aforesaid the second heat radiation chamber has the second air inlet and the second air outlet.

Further, between described the first heat radiation chamber and the second heat radiation chamber, be formed with uncovered heat dissipation region, this heat dissipation region bottom is the first described air outlet, and top is the second described air inlet.The setting of heat dissipation region is beneficial to and produces venturi benefit, accelerates convection current.

Described heat radiation chamber is substantially S-shaped, can be also straight tube shape, again or other bents, but take S shape for preferred.

Consider easily manufactured property, described radiator is formed by a plurality of metal forming material laminatings, and described the first heat radiation chamber and the second heat radiation chamber form on each metal forming material from bottom to top, each heat dissipation region is formed by the gap between adjacent metal forming material.

The first described air inlet, the first air outlet, the second air inlet and the second air outlet one of are at least provided with mesh plate, and this mesh plate cavity length direction of relatively dispelling the heat is skewed setting, design like this, and convection effects is good, rapid heat dissipation.

As preferably, described heater comprises heat-generating pipe and a plurality of heat-dissipating fin, and this heat-dissipating fin is radial arrangement in heat-generating pipe circumferentially and be connected and fixed with a fixed head in a side.

Compared with prior art, the invention has the advantages that: adopt a plurality of heat radiation air outlets from bottom to top, heat radiation is highly reduced, when user uses, from pin, start heating, finally arrive whole health, again owing to adopting the design of segmentation air-out, make final not high from heat radiation air outlet temperature out, be difficult for scalding human body, in addition, whole multistage heat radiation, energy consumption is relatively low, overall structure is simple, easy to assembly quick, easily produces.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.

Embodiment, as shown in Figures 1 to 4, warmer in the present embodiment comprises radiator 1, be located at the heater 5 in radiator 1 and be located at the control panel 10 of radiator 1 front end face, the accommodating cavity 11 of upper and lower two horizontally sets of radiator 1 and a plurality of 2, two, heat radiation chamber heater 5 that supplies air convection current from bottom to top and longitudinally arrange are horizontally set in accommodating cavity 11 and run through heat radiation chamber 2.

As shown in Figure 2 and Figure 4, heat radiation chamber 2 in the present embodiment is substantially S-shaped, heat radiation chamber 2 has the first heat radiation chamber 23 and the second heat radiation chamber 22 from bottom to top, heater 5 respectively through the first heat radiation chamber 23 and second heat radiation chamber 22, the first heat radiation chamber 23 has the first air inlet 231 and the first air outlet 232, the second heat radiation chambeies 22 have the second air inlet 221 and the second air outlet 222.

Further, between the first heat radiation chamber 23 and the second heat radiation chamber 22, be formed with uncovered heat dissipation region 21, these heat dissipation region 21 bottoms are the first air outlet 232, and top is the second air inlet 221.

Consider easily manufactured property, radiator 1 is formed by a plurality of metal forming material 4 laminatings, and the first heat radiation chamber 23 and the second heat radiation chamber 22 form on each metal forming material 4 from bottom to top, each heat dissipation region 21 is formed by the gap between adjacent metal forming material 4.Particularly, metal forming material 4 is successively according to positive and negative, positive and negative layout.
