Description
Technical field
The utility model relates to small-sized young silkworm for educating the automatic control apparatus equipment of temperature humidity that occasion is used.
Background technology
Young silkworm is for to educate be to raise the immature silkworm that has just hatched, to the requirement of temperature, humidity than higher, careless slightly will cause young silkworm sick, dead, yield poorly.And the warm and humid automatic control equipment on the market is applicable to big-and-middle-sized professional greenhouse mostly, the general three-phase alternating-current supply that adopts, power is bigger, cost an arm and a leg, can regulate temperature, humidity in the larger context, but be not suitable for plastic film canopy that the small individual raiser uses, educate simple greenhouse such as account, simple building.Above-mentioned factors makes the temperature in compact simplified greenhouse, humidity not reach requirement, causes easily that to raise kind sick, dead, directly causes output to descend, and brings economic loss to the raiser.Chinese patent ZL200420091468.8 discloses a kind of temperature and humidity automatic controller, can be temperature automatically controlled to compact simplified greenhouse, control is wet, but having defective is to adopt the poor effect of ultrasonic ultrasonic delay line memory humidification, reason is that the water smoke that ultrasonic ultrasonic delay line memory produces is the water smoke of the water generates under the room temperature, water smoke sinks while spreading indoor, range of scatter is little, and speed is unhappy, causes indoor humidity inhomogeneous easily.
The utility model content
The purpose of this utility model is that a kind of temperature and humidity automatic controller will be provided, simple greenhouse such as it is not only applicable to the plastic film canopy, educate account, simple building, and the temperature and humidity control performance is good, humidification speed is fast, and the humidification scope is wide, and the indoor humidity consistance is better, in addition, power is little, and volume is small and exquisite, uses single-phase alternating current just can use.
The purpose of this utility model is achieved in that a kind of temperature and humidity automatic controller, the lead, temp control switch, the humidity gauge tap that comprise shell frame, connection power supply, described temp control switch is electrically connected with an electric heater unit at least, and be installed on the described shell frame, the humidity gauge tap is electrically connected with a hot-water heating system at least, and is installed on the described shell frame.
Owing to adopt such scheme, the temperature and humidity control function combinations together, because of hot-water heating system is heated into hot water or boiling water with water, the vapours rate of propagation that produces is fast, and range of scatter is wide, and is better than the diffusion of normal temperature water smoke, improved the homogeneity of indoor humidity, on the other hand, can not reduce indoor temperature in the vapours diffusion process, this has more Practical Performance in cold season.And whole equipment volume is small and exquisite, adopts single phase poaer supply power supply again, and power is little, can be at the plastic film canopy, educate in the simple greenhouse such as account and use, so do not need special-purpose greenhouse just can raise young silkworm, greatly reduce individual raiser's input in advance.Particularly adopt two or more shell framves that separate, on one of them shell frame temp control switch and circuit are housed, on another shell frame humidity gauge tap and circuit are housed, perhaps temp control switch, humidity gauge tap and circuit are installed on the shell frame, remaining each shell frame is equipped with electric heater unit and hot-water heating system, also can electric heater unit be housed part shell frame, another part shell frame is equipped with hot-water heating system, and is electrically connected with temp control switch, humidity gauge tap correspondence.Be placed on the greenhouse as required everywhere, a plurality of electric heater units and hot-water heating system are worked together, and centralized control then can be applicable to the big slightly greenhouse of area, has bigger practical value, can be numerous raisers and saves great amount of investment.
