And in the prior art, it is carried out by opening roof window or side window or can be allowed in greenhouse by the dehumidifying of exhaust fan forced ventilation Sharp temperature drop, it is serious plant to be allowed to freeze to death in a short time.

Chinese patent CN104012345A discloses a kind of Winter Solar Greenhouse dehumidification device, is returned using total heat recovery heat exchanger The heat in waste air has been received, the temperature of outdoor fresh air is effectively increased, while can be used electric heater when temperature is lower to room Outer fresh air is heated, and is avoided the drawbacks of room temperature is greatly reduced while dehumidifying in conventional method, is met crop and exist Requirement of the cold season to temperature and humidity, inhibits the generation of crop disease to a certain extent.But the patent dehumidification device is installed It is at high cost, and energy consumption is high for electric heater, rate of breakdown is high, increases planting cost.

Utility model content

The purpose of the utility model is to provide a kind of active Solar Greenhouse in Winter dehumidification devices, can not only be indoor by temperature High humidity gas excludes, and is able to maintain the temperature in greenhouse；And may not need electric heater, low energy consumption.

A kind of active Solar Greenhouse in Winter dehumidification device described in the utility model, including frame, on frame Connect at the top of film-coiling device and film, preceding wall and back wall, frame and preceding wall and back wall；Frame is at preceding wall top Equipped with air inlet, the air inlet moves towards setting hot air duct along heliogreenhouse, installs spray head on pipeline；The hot air duct It is connected with heat blower；Several ventilation shafts are buried in the back wall, the ventilation opening of ventilation shaft upper end is opened in rear wall Body inner upper end, ventilation shaft bottom end connect greenhouse room outside steering ventilation shaft, the steerings ventilation shaft be set to before Exhaust duct outside wall or outside back wall is connected, and the exhaust duct exhaust ports are equipped with blower, and exhaust duct Exhaust outlet vertical direction height be ventilation opening vertical direction height half below.

The film of the utility model can be any material for being used for greenhouse in the prior art, not only include common Plastic film, or sunshade net etc..

The air inlet of the utility model can roll the gap of film formation directly for film-coiling device, and the width in gap can root According to needing the degree of hydrofuge to be controlled.

The hot air duct of the utility model can be for for carrying the pipeline of hot wind, such as common PE is managed in the prior art Road.The number of hot air duct upper nozzle can be configured according to temperature conditions.

Further, vent check valve is equipped at ventilation opening described in the utility model, vent check valve can be with existing It commonly can satisfy the structure that can play air blow back of sun light green house needs, such as relatively simple blade in technology Structure.

Further, exhaust duct bottom is equipped with water storage tank, and water storage tank is equipped with discharge opening.The water storage tank of the utility model A part of containment structures of one section of formation can be extended for exhaust duct bottom pipe, or one water storage in ground is separately provided Slot, discharge opening can be simple valve or plug.

Further, the exhaust outlet vertical direction height of the exhaust duct of the utility model is ventilation opening vertical direction height One third between half.

Further, the blower is axial flow blower.

The number of the ventilation shaft of the utility model can be selected according to the humidity weather etc. of different regions, if more Humid region can be more, and comparatively dry area can be relatively fewer.

The advantage of the utility model compared with the existing technology:

(1) the utility model is connected by ventilation shaft pre-buried in rear wall, and with outdoor steering ventilation shaft is set to, Effectively maintain the rear wall of heliogreenhouse and the globality and heat storage capacity of side wall；

(2) negative pressure that the utility model utilizes blower to be formed allows indoor and outdoor to form ventilation circuit, solves heliogreenhouse Winter hydrofuge problem, effectively excludes indoor high humidity gas, reduces the humidity of heliogreenhouse, while passing through in greenhouse air inlet Longitudinally arranged nozzle sprays hot wind, forms one of hot wind curtain wall, outdoor air enters greenhouse by air inlet, in air inlet Place to realize that heat exchanges, is achieved the effect that wet down is kept the temperature, is built optimum environment for plant due to nozzle warm air curtain, Avoid plant injury, increasing both production and income；

(3) setting of exhaust outlet vertical direction height and ventilation opening vertical direction height relationships, further guarantees not When work, the heat storage capacity and heat insulation effect of heliogreenhouse, winter can in entire ventilation circuit self-assembling formation ventilation it is short Road avoids the generation of heat bridge and the leakage of heat.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of the hot air duct and spray head from preceding wall direction section view；

Wherein: 1 frame, 2 film-coiling devices, wall before 3,4 back walls, 5 air inlets, 6 ventilation shafts, 7 turn to ventilation shafts, and 8 Exhaust duct, 9 blowers, 10 vent check valves, 11 water storage tanks, 12 hot air ducts, 13 spray heads, 14 heat blowers, arrow indicate Wind direction.
