The utility model content
The utility model is at the insensitive situation of existing product non-automatic-reset thermal trip response speed, and the electric auxiliary heating device of fast, the safe and reliable air-conditioner of a kind of response speed is provided, to overcome weak point of the prior art.
Press the electric auxiliary heating device of a kind of air-conditioner of this purpose design, comprise the heating appliances that is arranged between outlet frame and the evaporimeter and reset certainly thermal trip and non-automatic-reset thermal trip, its architectural feature right and wrong are positioned at the upper end of heating appliances from the thermal trip that resets.
Described upper end, sidepiece or the middle part that is positioned at heating appliances from the thermal trip that resets.
The distance of described non-automatic-reset thermal trip and heating appliances upper end is 3～40mm.From the sidepiece of reset thermal trip and heating appliances or the distance at middle part is 3-40mm.
Described heating appliances is electric heating tube or PTC semiconductor.
Good effect of the present utility model:
The non-automatic-reset thermal trip is installed in the upper end of heating appliances, this structural design, when air-conditioner normally uses, blower fan work, what the non-automatic-reset thermal trip was experienced is the heat of heat pump and the radiation of heating appliances top, but because the heat that heating appliances produces can be discharged from the air channel rapidly under the air-flow effect, at this moment, the heating appliances top is a low-temperature condition, the place ahead temperature than heating appliances is low, so the non-automatic-reset thermal trip almost can't experience the heat that heating appliances produces, so non-automatic-reset thermal trip setting rated function temperature is lower, can shorten the out-of-work response time of electric auxiliary heating device, alleviate the structural member distortion.When automatically controlled inefficacy occurring, when indoor fan was not transferred the electric auxiliary heating device unlatching, the non-automatic-reset thermal trip moved, and whole electric auxiliary heating device is permanent to quit work (having only the non-automatic-reset thermal trip that more renews just can rework); Avoid responding to insensitive because of the non-automatic-reset thermal trip, have only when resetting the thermal trip action, after temperature lowers, thermal trip resets from resetting, whole heating appliances works on again, so frequent movement, the service life of having reduced the thermal trip that resets certainly on the one hand, air-conditioning outlet frame heat accumulation simultaneously causes the distortion of outlet frame working of plastics to come off and causes fire easilier.
Also can be installed in the upper end of heating appliances from the thermal trip that resets, improve induction sensitivity.
