The specific embodiment
Embodiment one;
A kind of multi fan warmer overtemperature safety guard embodiment one; as shown in Figure 1; the heat that warmer 10 among the figure adopts two blower fans that are connected in parallel 11 that heating is sent out blows out, and described heating is a PTC ceramic heating assembly 12, comprises PTC ceramic heating plate 121 and heat sink 122.Described overtemperature safety guard comprises temperature controller and the electric-controlled parts 13 that is installed in described warmer 10 housings.As shown in Figure 3, in the present embodiment, described temperature controller is a bimetal chip thermostat 20, comprises bimetal leaf 21 and contact, and joins insulation crust 22, and described bimetal leaf 21 and contact cover are located in it.Described bimetal leaf 21 is connected in the power supply circuits of heating by lead 23.
Referring to Fig. 1 to Fig. 3, form place's areola 14 on described warmer 10 inner walls, this areola 14 is provided with near the heat sink 122 of PTC ceramic heating assemblies 12 and equates (areola 14 is arranged on A place as shown in Figure 1 to Figure 3) with distance between adjacent two blower fans 11, and described bimetal chip thermostat 20 is installed in the described areola 14.
Because described A place is that bimetal chip thermostat 20 installation sites and two blower fans 11 are equidistant, so its temperature is the mean temperature on corresponding two blower fans, 11 wire lengths basically.If one of them blower fan 11 hinders shutdown for some reason; PTC ceramic heating assembly 12 front face megadyne temperature degree rise; near curie point; the then also corresponding rising of the temperature at A place; surpass its secure setting, this variations in temperature is passed to bimetal chip thermostat 20 by air, and its bimetal leaf moves 21 break contacts; the power supply of cutting off PTC ceramic heating assembly 12 makes it to quit work, and realizes the overtemperature safeguard protection.After fixing a breakdown, PTC ceramic heating assembly 12 blows out at blower fan 11 under the cooling of cold wind and is in normal working temperature, and the contact of bimetal leaf 21 is closed again.
In some Application Example, described bimetal chip thermostat 20 needn't be provided with insulation shell 22, and bimetal leaf 21 directly is fixed in the cavity 14 on main frame 10 enclosure walls.
Equally, in some Application Example, described heating also can adopt traditional heating wire that is fixed on the heat-resistant insulating board (as micarex).
Embodiment two:
A kind of multi fan warmer overtemperature safety guard embodiment two, as shown in Figure 4, present embodiment two is basic identical with structure and the principle of embodiment one, and difference is:
1. in the present embodiment two, the heat that warmer 10 adopts three blower fans that are connected in parallel 11 that heating is sent out blows out, and described heating adopts finned metal electric heating pipe 12 ', comprises electrothermal tube 123 and radiating fin 124.
2. because blower fan 11 has three, correspondingly, bimetal chip thermostat 20 is provided with two (configurable or do not dispose insulation crust 22), and they are connected in series in the power supply circuits of metal electric heating pipe 12 '.Form two place's areolas 14 on described warmer 10 inner walls, this two places areola 14 is arranged on (two B places in the diagram) near the radiating fin 124 of described metal electric heating pipe 12 ', and described each B place equates with the centre distance of adjacent separately per two blower fans 11 in the position; Described two bimetal chip thermostats 20 are fixed on respectively in described two place's areolas 14.
During warmer 10 work; as long as any blower fan 11 break down shut down cause heating in its vicinity the position temperature surpass secure setting; the bimetal leaf of that bimetal chip thermostat 20 of corresponding position moves 21 break contacts; the power supply of cutting off metal electric heating pipe 12 ' makes it to quit work, and realizes the overtemperature safeguard protection.
Embodiment three:
A kind of multi fan warmer overtemperature safety guard embodiment two; as shown in Figure 5 and Figure 6; in the present embodiment; temperature controller adopts electronic temperature controller 20 '; comprise the signal transmssion line 27 and the executive component 25 of temperature-sensing element 26, control element 24, connection temperature-sensing element 26 and control element 24, control element 24 and executive component 25 are included in the main electric-controlled parts 13 of warmer.Described temperature-sensing element 26 is thermocouple (or thermistors), and be provided with insulating coating 2261, be fixed in the lump in the areola 14 on main frame 10 enclosure walls, this areola 14 is near the heat sink 122 of PTC ceramic heating assembly 12, and equate (areola 14 is arranged on the A place in the diagram) with distance between two blower fan 11, as shown in Figure 6; Control element 24 is the temperature control units in warmer 10 master boards, after handling, the signal of telecommunication that it sends temperature-sensing element 26 here is converted to the instruction of control PTC ceramic heating assembly 12 work, this instruction is carried out by executive component 25, executive component 25 is relay normally, also high-power silicon controlled rectifier, triode belong to the element in the electric-controlled parts 13 of warmer 10.The concrete control principle of electronic temperature controller 20 ' all belongs to conventional art, repeats no more herein.
Need to prove, in other application example, when the blower fan of warmer has three or four, correspondingly the temperature-sensing element 26 of electronic temperature controller 20 ' (for example thermocouple) is provided with two or three and is electrically connected to control element again, is installed in the position that equates with the centre distance of adjacent separately per two blower fans 11 respectively; And, a cover control element 24 and the executive component 25 that all temperature-sensing elements 26 (for example thermocouple) can be shared.During warmer 10 work; as long as any blower fan 11 break down shut down cause heating in its vicinity the position temperature surpass secure setting; the temperature-sensing element 26 of that electronic temperature controller 20 ' of corresponding position promptly sends signal; be transferred to control element 24; and then make it to quit work by the power supply that executive component cuts off heating, realize the overtemperature safeguard protection.
