Fig. 3 is, when opening described the first valve, and when closing described the second blower fan and described the second valve, air current flow direction (shown in the arrow) schematic diagram of ventilation equipment;
The specific embodiment
The structural representation of the ventilation equipment that Fig. 1 provides for the utility model embodiment.As shown in Figure 1, these ventilation equipment comprise: housing 11 is provided with the first wind chamber 111, the second wind chamber 112 and electric-controlled plate 14 in housing 11;
Be provided with in the first wind chamber 111 in the first blower fan 12, the second wind chambeies 112 and be provided with the second blower fan 13;
Be provided with the first valve 117 between the first wind chamber 111 and the second wind chamber 112;
The first wind chamber 111 is provided with exhaust outlet 113 and the second return air inlet 115;
The second wind chamber 112 is provided with outdoor air inlet 119, the first return air inlet 114 and mixes air port 116;
Sensor on electric-controlled plate 14 is for detection of indoor air quality; Wherein the first blower fan 12 keeps normally open when opening of device, and the detected value of receiving sensor when electric-controlled plate 14 is closed the second blower fan 13 and the second valve 118 during more than or equal to default safety value instruction, opens the first valve 117; And reach time of setting when the cumulative time that close the second blower fan 13 and the second valve 118, or during less than the safety value preset, close the first valve 117 when the detected value of indoor air quality, open the second blower fan 13 and the second valve 118.
Alternatively, as shown in Figures 2 and 3, in the ventilation equipment that the utility model embodiment provides, also be provided with air processor in the second wind chamber 112.
This air processor can comprise at least a in electrical auxiliary heater 21, dust screen pack 22, electrostatic precipitation net 23, active carbon net 24, photocatalyst net 25 and uv disinfection lamp 26.
Alternatively, in the ventilation equipment that the utility model embodiment provides, also can be provided with heat-exchange apparatus between the first wind chamber 111 and the second wind chamber 112, figure here.
Wherein, electric heater 21 was used for when winter, and is indoor with sending into after outdoor air heat, the step-down that makes indoor temperature not because the temperature of outdoor air is low.Dust screen pack 22, electrostatic precipitation net 23, active carbon net 24, photocatalyst net 25 and uv disinfection lamp 26 can effectively play catharsis to air, make indoor air more be conducive to people's health.
As shown in Figure 2, during less than default safety value, illustrate that room air is up to standard when the detected value of indoor air quality:
When detected value was up to standard, electric-controlled plate 14 was controlled the first valve 117 and is closed, and opens the second blower fan 13, opened the second valve 118 and opened according to a certain percentage; The indoor wind that the outdoor air of coming in from the second valve 118 and the first return air inlet 114 are come in is after the interior mixing of housing 11, heating and purification through electrical auxiliary heater 21, dust screen pack 22, electrostatic precipitation net 23, active carbon net 24, photocatalyst net 25 and uv disinfection lamp 26, rotated by the second blower fan 13 afterwards and forms air-flow and pass and mix outside the 116 outflow housings 11 of air port, send at last indoor.Like this, can the indoor air of circularly purifying, again can be with outdoor oxygen replenishment to indoor.Dirty room air is discharged to outdoor through the second return air inlet 115 by the first blower fan 12.Wherein, the second return air inlet 115 is arranged on the toilet, because the first blower fan 12 is often opened, has avoided the foul atmosphere of toilet to pour in down a chimney in other rooms.
As shown in Figure 3, during more than or equal to default safety value, illustrate that room air is not up to standard when the detected value of indoor air quality:
When detected value was not up to standard, electric-controlled plate 14 was controlled the first valve 117 and is opened, and closes the second blower fan 13 and the second valve 118; This moment, dirty room air entered the second wind chamber 112 through mixing air port 116 and the second blower fan 13, simultaneously dirty room air also enters the second wind chamber 112 through the first return air inlet 114, then through the first valve 117, discharge outdoor by the first blower fan 12 at last; So, mix air port 116 and just converted indoor return air inlet to this moment, add the first return air inlet 114 and the second return air inlet 115, just increased the gross area of return air inlet, so just increased accordingly from the indoor foul atmosphere that enters in housing 11 in the unit interval, so greatly shortened the time of discharging indoor foul atmosphere.
When detected value is not up to standard, in the second wind chamber 112 from mixing just in time opposite when up to standard with detected value through the airflow direction of air processor of the air-flow of coming in air port 116, above dust screen pack 22, electrostatic precipitation net 23, active carbon net 24 and photocatalyst net 25 are just in time one oppositely blow, so played again the effect of cleaning.
The ventilation equipment that the present embodiment provides, by utilizing sensor to detect indoor air quality, wherein said the first blower fan keeps normally open when opening of device, the detected value of receiving sensor when electric-controlled plate is during more than or equal to default safety value instruction, close described the second blower fan and described the second valve, open described the first valve, poor air is discharged rapidly to make indoor air quality; And the cumulative time that ought close described the second blower fan and described the second valve reaches the time of setting, or when the detected value of indoor air quality during less than default safety value, close described the first valve, open described the second blower fan and described the second valve, make outdoor fresh air add to rapidly indoor, can the indoor air of circularly purifying, again can be with outdoor oxygen replenishment to indoor, thus improved indoor air quality.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
