Description

Stand type air purification system

The present invention relates to a stand type air purifying system installed on a window frame to directly purify outdoor air and introduce it into a room, thereby simultaneously performing ventilation and air purification.

Generally, the ventilator is a device that keeps the indoor air in a pleasant state by letting outdoor air into the indoor and discharging indoor air to the outdoor.

In recent years, air pollution due to environmental pollution has become serious, and dust and fine dusts have increased, and indoor air can not be kept clean by simple ventilation that circulates outdoor air and indoor air.

Accordingly, an air purifier installed in a room to purify indoor air has been increasing. However, since the air purifier installed in the room purifies the contaminated room air, there is a problem that it is difficult to keep the indoor environment always pleasant.

To solve this problem, a window type air purification system has been developed in which outdoor air is directly purified and then supplied to the room to simultaneously perform ventilation and air purification.

The frame mounting portion includes an upper rail groove 122 formed in the upper surface of the housing 10 and inserted into the upper frame, a lower rail groove 124 formed in the lower surface of the housing 10 and inserted into the lower frame of the window frame 150, .

The air purification system of the present invention is provided with a filter unit replacement timing notification unit that indicates the replacement timing of the filter unit.

As shown in FIG. 8, the filter unit replacement timing notifying unit includes a display unit 130 for indicating a filter replacement timing to a user or an air purification system installation company, a filter for detecting the state of the filter unit 20, A state measuring unit 140 and a controller 130 for displaying a filter replacement state on the display unit 130 when a signal value applied from the filter state measuring unit 140 is equal to or greater than a predetermined value in accordance with a signal applied from the filter state measuring unit 140, (Not shown).

The display unit 130 can be displayed on the smartphone 134 of the user, the operation unit 136 installed on the wall surface of the room for operating the air purification system, and the management unit 132 of the construction company for confirmation by the air purification system construction company.

That is, the display unit 130 informs the user who uses the air purification system and the construction company that installed the air purification system of the filter unit replacement timing.

The filter state measuring unit 140 may be a pressure sensor installed at the rear of the filter unit 20 and measuring the pressure of the air passing through the filter unit 20, An air flow sensor that senses the flow rate of the air that has passed through the unit 20 may be used and a load measurement sensor that measures the load of the drive motor of the air blowing unit may be used.

When the pressure sensor is used, the pressure of the air passing through the filter unit 20 is measured to determine whether the filter unit 20 is replaced. In the case of the air flow sensor, the flow rate of the air passing through the filter unit 20 is measured In the case of the load measuring sensor, the load amount of the driving motor of the air blowing unit is measured to determine whether the filter unit is replaced or not.

9, the filter unit 20 includes a filter member 24 having a plurality of pores and a filter member 24 mounted on an edge of the filter member 24 to support the filter member 24 and to be connected to the air inlet 42 And a supporting member 22 attached thereto.

A filter mounting portion 26 is formed at regular intervals along the longitudinal direction and a filter member 24 Are attached to each other to firmly support the filter member 24.

10 is a plan view of a filter unit according to another embodiment of the present invention. The filter member (52) of the filter unit (34) is formed in a corrugated shape so as to widen the contact area with air.

The filter member 52 is formed of a porous nano-web 53 as shown in Fig. 11, and the porous nano-web 53 is prepared by mixing an electrospun polymer material and a solvent at a predetermined ratio to form a spinning solution, The spinning solution is spinned by the electrospinning method to produce the nanofibers 54 and the nanofibers 54 are accumulated so as to have micropores 56. [

The polymeric material used in the present invention may be electrospun. For example, synthetic and natural polymers may be used. One or more of these polymers may be used in combination.

Among the polymer materials, particularly preferred as the filter material of the present invention are polyacrylonitrile (PAN), polyvinylidene fluoride (PVdF), polyester sulfone (PES), polystyrene (PS), polyvinyl chloride Polyvinylchloride), polycarbonate (PC), polyurethane (PU), polyurethane (PU), polyvinylidene fluoride (PVdF) and polyacrylonitrile PES, PVdF and thermoplastic polyurethane (TPU), PVC, PC, etc. can be mixed and used.

As the spinning method applied to the present invention, there can be used a nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type nozzle type Can be used.

Since the porous nano-web 53 is manufactured by the electrospinning method, the thickness is determined according to the amount of radiation of the polymer material. Therefore, there is an advantage in that it is easy to make the thickness of the porous nano-web 53 to a desired thickness.

Accordingly, since the average size of the pores and the pores are determined according to the thickness of the porous nano-web 53, it is possible to produce a pore average size suitable for filtering nano-sized fine dusts of the air purification system.

The diameter of the nanofibers 54 is in the range of 0.5 to 3 mu m, and the average pore size is preferably 0.2 to 10 mu m or less.

Since the filter unit 34 according to the present embodiment is installed in a state exposed to the outside, the porous nano web 53 basically has a pore size that can not allow rainwater to pass through. A water repellent coating layer is formed on the surface of the porous nano web 53 to prevent rain water from penetrating into the porous nano web.

12, since the porous nano web 53 is exposed to the outside as shown in Fig. 12, the strength reinforcing portion 58 may be formed to prevent scratches or the like from being generated on the surface of the porous nano web 53 .

The strength reinforcing portion 58 is mixed with a pigment, a binder, and a solvent at a certain ratio and applied to the surface of the porous nano-web 53. The pigment used in the strength reinforcing portion 58 is a black or color pigment, and various colors and tones can be realized depending on the amount and type of pigment used.

The strength reinforcing portion 58 may be applied by gravure printing, coating or the like, and it may be formed by electrospinning as well as the method of forming the porous nano web 53.

The strength reinforcing portion 58 includes a binder for reinforcing the strength of the porous nano-web 53, thereby enhancing the surface strength of the porous nano-web 53 and providing scratch resistance.

That is, since the porous nano-web 53 is manufactured by the electrospinning method and the nanofibers 54 are accumulated, pores 56 are formed between the nanofibers, and the strength reinforcing portion 58 is formed between the nanofibers 54, The strength of the porous nano web 53 is enhanced. Therefore, it is possible to minimize the deformation of the porous nano-web 53 against the external impact or sound pressure.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein. Various changes and modifications may be made by those skilled in the art.

It can be applied to a stand type air purification system which can simultaneously perform ventilation and air purification since outdoor air can be directly purified and introduced into a room.
