Abstract

The utility model discloses a pressure exhaust-type household fresh air system which comprises an external wall air port, a fresh air port, a partition wall ventilation slot, an air exhaust port and a pressure exhaust fan box; in household, each external wall of the room which can be directly communicated with the exterior is provided with an external wall air port, and the partition walls of the other rooms which cannot be directly communicate with the exterior are provided with partition wall ventilation slots; the pressure exhaust fan box and the air exhaust port can be mounted at the corners of the washing room; and the mud air entering the washing room from each room is connected with the pressure exhaust fan box through an air exhaust port pipeline so as to be finally pressed out of the door so as to form negative pressure. The fresh air system enables the fresh air to pass through each room in the house so as to ventilate each corner, so that the air cleanness in the house is high, and the health of the human body is facilitated; a negative pressure exhaust device used for an air supply system is small in size, and is not limited by the space and a small number of pipelines are arranged; therefore, the pressure exhaust-type household fresh air system is very suitable for the household.

Description

A kind of have press air-exhaust type household VMC

Technical field

The utility model relates to new wind field, relates in particular to a kind of household VMC of pressing air-exhaust type that has.

Background technology

The existing mode of improving the home air quality has: photocatalyst, charcoal absorption and ventilation etc.Though purifying, photocatalyst can continue to purify air, it is passive mode that but photocatalyst purifies air, volatilization problem that can not the contaminated solution source, that is to say the pollutant volatilization a bit, photocatalyst absorption is decomposed a bit, and human body and photocatalyst can not reach the effect of elimination simultaneously at the absorption pollutant.Will stop absorption after charcoal absorption is saturated, need periodic replacement or be exposed to the sun the disposal cost costliness.Gravity-flow ventilation can be diluted and be got rid of indoor air pollutants, though can keep air unimpeded to a certain extent, follows noise, sand and dust, mosquito, problem such as heat insulation.Conventional fresh air conditioner has requirement to the building floor height, and the building floor height is generally on the low side at present, generally below 2.8 meters, if consider factor such as furred ceiling, all 2.5 meters of less thaies of free height is installed between fresh air conditioner equipment back room, can bring sense of depression to the people.

Simultaneously, standard GB/T18883-2002 pair of resh air requirement regulation per capita: resh air requirement should be less than 30m ³/ h everyone.Thereby, need a kind of pipeline be installed by the high-quality household VMC that is subjected to the restriction of building floor height less and not at present.

Summary of the invention

Weak point at existing household VMC, the purpose of this utility model is will be with the limited space degree of minimum pipe arrangement, minimum, provide a kind of indoor-outdoor air that can replace (promptly to discharge indoor foul atmosphere with negative pressure, introduce the new wind that filters), thus with fresh air, clean household VMC in the holding chamber.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of have press air-exhaust type household VMC, comprise exterior wall air port, fresh wind port, partition wall ventilative groove, exhaust outlet and the pressure air box is arranged, in the household each with the outdoor room exterior wall that can directly be communicated with on all have an exterior wall air port, other can not have the partition wall ventilation slot with the room that outdoor air directly is communicated with on partition wall; There are pressure air box and exhaust outlet to be installed in the toilet; The turbid wind that each room enters the toilet is connected with outside the final delivery chamber of pressure air box by the exhaust outlet pipeline.

Described exterior wall air port is that exterior wall hides the rain air port, and it is indoor to prevent effectively that the rainy day rainwater is splashed into, and keeps room air too not moist.

Described exhaust outlet and have the pressure air box to be installed in the corner of toilet.Described have the pressure air box to adopt the high-static pressure fan case, not only realized reducing noise, but also reached the purpose of ventilation.

The utility model has following some beneficial effect with respect to prior art:

1. this household VMC changes the wind better effects if with ventilation and negative pressure ventilation formula VMC: new wind is through each room in the family, and the effect of ventilation is all played in the every nook and cranny, and the air purity height helps health in the room.

2. have the pressure air box to be installed in the toilet, simple in structure, energy consumption is low, noise is little, disassembly, cleaning are all very convenient.

3. air supply system is little with ventilation and negative pressure ventilation plant area area, and pipe arrangement is few, is not subjected to spatial constraints, is well suited for household and uses.

Description of drawings

Fig. 1 is that household VMC of the present utility model is applied in the layout in the building.

Fig. 2 is the vertical view of high-static pressure fan case among the utility model embodiment.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further details.

With reference to Fig. 1 is that present embodiment has the architectural plane schematic diagram of pressing air-exhaust type household VMC.1 for there being the pressure air box, and 2 is exhaust outlet, and 3 is fresh wind port, and 4 is the exterior wall air port, and 5 is new wind, and 6 are the ventilative groove of partition wall, and 7 is guest bedroom, and 8 is pipeline, and 9 is the toilet, and 10 is the kitchen, and 11 is the dining room, and 12 is the parlor, and 13 is master bedroom, and 14 is balcony.Indoor foul atmosphere is discharged through pressure air box 1 is arranged by exhaust outlet 2 earlier, forms negative pressure, and each zone is oozed wind by the ventilative groove 6 of partition wall to toilet 9.Simultaneously, outdoor fresh air is by the exterior wall air port 4 on the wall, again in fresh wind port 3 inlet chambers, finally realizes the effect that purifies air with less line arrangement.Each can with the outdoor room exterior wall that directly is communicated with on all have an exterior wall air port 4, and can not just on partition wall, stamp partition wall ventilation slot 6 with the room that outdoor air directly is communicated with, so just can keep the wind of the freshest cleaning to enter the effect that reaches ventilation by rooms such as bedroom 7 and 13, kitchen 10, parlors 12 from the open air.There are pressure air box 1 and exhaust outlet 2 all to be installed in toilet 9.The turbid wind that can earlier each room be entered toilet 9 is by exhaust outlet 2, because an exhaust outlet is furnished with one the pressure air box is arranged, can be by exhaust outlet 2 through pressure air box 1 being arranged with foul smell outside the final delivery chamber, form negative pressure, the wind in bedroom 7 and 13, parlor 12, kitchen 10 and dining room 11 all imports toilet 9 by the partition wall ventilation slot again so like this.Fresh air is by in the natural air inlet mouth inlet chamber on the wall simultaneously.So form new wind circulation, reach the purpose of pure air.At area is 130m ²About the household house type defended of two Rooms two, three Room in, the installation nominal air delivery is 150m ³/ h high-static pressure fan case, its installed power are 16W, because this VMC is start in 24 hours, so one day power consumption 384W, power consumption is low.

This new wind cyclic process connects the pure and fresh cleaning that reaches the toilet air to greatest extent with minimum pipeline, has saved cost, has saved the pipeline floor space of VMC, make this VMC can be to greatest extent be not subjected to spatial constraints.
