Description
The utility model belongs to the ventilation plant of discharging and send into air by wall, relates to a kind of energy-conservation ventilation fan that indoor and outdoor air is changed that is applicable to, is the improvement of prior art.
The existing device that is used to improve air temperature generally all adopts air conditioner, because the room of the device that installs an air-conditioner must keep semi-closed state, thereby easily makes the indoor air muddiness, oxygen lacks, and influences health.Chinese patent ZL95243885.2 discloses a kind of " energy-conservation ventilation fan ", it is characterized in that: except that including a ventilating fan, also include a blowing fan and have two intake grills and two exhaust outlets, middlely separate and form the bellows in internal and external layer wind district with a dividing plate; Inside and outside floor wind district respectively has an intake grill and exhaust outlet, and ventilating fan and blowing fan are separately positioned on one deck wind district and intake grill and exhaust outlet; Place side by side mutually to be nested with and form the two air channels of spaced-apart spirality thin-walled thereby respectively be provided with one group in the internal and external layer wind district in bellows, and inside and outside two groups of two air channels interconnect at the spirality center; The fixed edge that intermediate clapboard stretches out in bellows shell is fixed in wall hole or the window frame, and it is outdoor that the crosswind case that fan is housed is exposed to, and the opposite side bellows are positioned at indoor.Though this model utility can be with indoor muddy air and outdoor fresh air displacement, and fresh air temperature and room temperature in the inlet chamber are close, but because (1) ventilating fan and blowing fan all are positioned at a side, the center of gravity secundly, adopt intermediate clapboard to be fixedly mounted in wall hole or the window frame, must open bigger hole on wall or window, inconvenience is installed, stability in use and Security are relatively poor; (2) be positioned at outdoor ventilating fan and pass through the spirality air channel to indoor air draught, it is more relatively to consume energy; (3) adopt thin intermediate clapboard that Nei Feng district and exogenous wind district is isolated, the Nei Feng district is influenced by outdoor environment, and the air heat exchange effect is not really desirable.
The utility model adopts house sidings that Nei Feng district and exogenous wind district is isolated, thereby provides a kind of effect better energy-conservation ventilation fan by changing the position of ventilating fan.
Content of the present utility model is: a kind of energy-conservation ventilation fan, comprise: ventilating fan, blowing fan, outer panels, wainscot, the two air channels of inside and outside two groups of spirality thin-walleds that an intake grill and exhaust outlet are respectively arranged, the two air channels of inside and outside two groups of spirality thin-walleds are connected at the spiral center, and its feature part is to comprise:
An inner bottom plate, the two air channels of described external spiral shape thin-walled are arranged between this inner bottom plate and the described outer panels, described blowing fan is installed on this inner bottom plate and is positioned at the intake grill place in the two air channels of described external spiral shape thin-walled, and one group of bolt by symmetrical distribution between this inner bottom plate and the described outer panels connects; Thereby constitute the exogenous wind district;
An inner bottom plate, the two air channels of described spiral thin-walled are arranged between this inner bottom plate and the described wainscot, described ventilating fan is installed on this inner bottom plate and is positioned at the exhaust outlet place in the two air channels of described spiral thin-walled, and one group of bolt by symmetrical distribution between this inner bottom plate and the described wainscot connects; Thereby constitute the Nei Feng district;
The two air channels of described inside and outside two groups of spirality thin-walleds are connected by suction tude and steam outlet pipe at the spiral center; The length of this suction tude and steam outlet pipe is slightly larger than the thickness of house sidings, passes wall during use and is supported in the wall hole;
Link by the bolt that passes suction tude and steam outlet pipe respectively between described outer panels and the wainscot.
Compared with prior art, the utlity model has following characteristics:
When (1) using, indoor muddy air can be discharged on the one hand, on the other hand again can be simultaneously to the indoor fresh air of sending into, and because muddy air and fresh air effectively carry out heat exchange by thin-walled in the two air channels of long spirality, make fresh air and room temperature in the inlet chamber close, both effectively improve indoor air, and can prolong working life, energy-conservation of air conditioner again;
(2) ventilating fan and blowing fan lay respectively at Nei Feng district and exogenous wind district, symmetrical configuration compactness, employing suction tude and steam outlet pipe are communicated with the two air channels of internal and external screw shape and are supported in the wall hole, and house sidings is isolated with interior exogenous wind district, the heat exchange effect of turnover air is better, energy-conservation more obvious;
(3) simple and practical, produce safety easy, easy to install.
