Abstract
The invention discloses an electric auxiliary heating device of an air conditioner, which comprises a heating appliance arranged inside an air-out frame and a self-resetting thermal trip and a non-self-resetting thermal trip, and is characterized in that the non-self-resetting thermal trip is located in the upper end of the heating appliance. The self-resetting thermal trip is located in the upper end, the lateral part or the middle part of the heating appliance. The heating appliance is an electric heating tube or a PTC semiconductor. When in normal use of the air conditioner, the non-self-resetting thermal trip feels the heat radiated by a heat pump and the top of the heating appliance of the electric auxiliary heating device, the temperature is low, the non-self-resetting thermal trip sets a low stated action temperature, thereby the response time of stopping work of the electric auxiliary heating device is shortened, and the deformation of the structure members is reduced. The electric auxiliary heating device of an air conditioner has dedicated design, good performance, security and practicability. The response speed of the non-self-resetting thermal trip is accelerated by changing the position thereof, and the misfire phenomenon caused by the independent starting of the electric auxiliary heating device is fundamentally avoided.
Description
Technical field
The present invention relates to a kind of electric auxiliary heating device that is used for air-conditioner.The manufacturing technology field that belongs to air-conditioner.
Background technology
The electric auxiliary heating device that is applied to field of air conditioning at present is mainly the resistance-type heating, and its principal mode is that bareing alloy heater strip formula and composite tube heat two kinds, also has a kind of PTC semiconductor-type that is.The electric auxiliary heating device of cabinet-type air conditioner employing at present generally is contained in air outlet evaporimeter the place ahead by support 1, heat pump is heated carry out certain replenishing, and can effectively solve heat pump and heat not enough problem.According to GB 4706.32-2004 " specific (special) requirements of safe heat pump, air-conditioner and the dehumidifier of family expenses and similar applications electrical equipment "; utensil with the auxiliary electro-heat device that adds hot-air should have two thermal trips at least; one is the thermal trip 3 that resets certainly; another is a non-automatic-reset thermal trip 4, and non-automatic-reset thermal trip 4 protection temperature are wanted high tens degree from the thermal trip protection temperature that resets relatively.Cabinet-type air conditioner uses two thermal trips of electric auxiliary heating device all between the top and the bottom of heating appliances 2 vertical direction, simultaneously between heating appliances 2 and outlet frame wind guide strip, as shown in Figure 1 at present.When the automatically controlled inefficacy of appearance, indoor fan were not transferred the electric auxiliary heating device unlatching, this structure may react insensitive because of thermal trip, caused the distortion of outlet frame working of plastics to come off and caused fire easily, brought very big influence for broad masses' security of the lives and property.
Summary of the invention
The present invention is directed to 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 invention:
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.

Fig. 3 is the embodiment of the invention two structural representations.
Fig. 4 is the embodiment of the invention three structural representations.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Embodiment one: referring to Fig. 2, the heating appliances 2 in the electric auxiliary heating device is installed between outlet frame and the evaporimeter by support 1, and non-automatic-reset thermal trip 4 is positioned at the upper end of heating appliances 2, and the thermal trip 3 that resets certainly is positioned at heating appliances 2 middle parts.The distance of non-automatic-reset thermal trip 4 and heating appliances 2 upper ends is generally in 3～40mm scope, after heating appliances 2 independent unlatchings, non-automatic-reset thermal trip 4 can the most effective heat of experiencing heating appliances 2, be positioned at the sidepiece of heating appliances 2 from the thermal trip 3 that resets, with heating appliances 2 distance in the 3-40mm scope, experience the heat of heating appliances 2 middle part radiation.When non-automatic-reset thermal trip 4 apart from heating appliances 2 same distance; be installed in the place ahead and be installed in the top relatively; it is higher to be installed in the top sensitivity, and distance is far away more, and effect is outstanding more; because heat energy moves upward; and during the air-conditioning operate as normal, blower fan work can in time be discharged heat; non-automatic-reset thermal trip 4 is installed in heating appliances 2 tops ratio, and to be installed in heating appliances 2 the place ahead temperature lower, effectively protects 4 life-spans of non-automatic-reset thermal trip.Present embodiment heating appliances 2 is an electric heating tube.
Embodiment two: as shown in Figure 3, the non-automatic-reset thermal trip 4 and the thermal trip 3 that resets certainly all are positioned at the upper end of heating appliances 2 in the electric auxiliary heating device, help protection equally from thermal trip 3 and the raising sensitivity of resetting.Heating appliances 2 is an electric heating tube, does not state structure division with embodiment one.
Embodiment three: as shown in Figure 4, non-automatic-reset thermal trip 4 and the thermal trip 3 that resets certainly all are positioned at the upper end of heating appliances 2 in the electric auxiliary heating device, and heating appliances 2 is the PTC semiconductor, does not state structure division with embodiment one.
