Description

[0001] Air purifier and photocatalytic-air conditioning module for bed [

The present invention relates to an air purifier, and more particularly, to a bed air purifier and a photocatalyst-air conditioning module that can provide purified air having a proper temperature to a person in a bed.

A bed is one of the longest inhabited places in the house. There are many kinds of bed, such as a general mattress bed, a latex mattress bed, a water bed, a stone bed, etc. In addition to simply giving a feeling of being fluffy or comfortable, it is common to have a temperature control function such as a mattress.

If you buy a new bed or buy a new bed mattress, people who are sensitive to volatile organic compounds (VOCs) will suffer from new product syndromes (new furniture syndrome, sick house syndrome, etc.) from new furniture or new products. There are many cases. In particular, as mentioned earlier, bed is a place to stay while sleeping in one place, so if a room with a bed is a VOC environment, the person sleeping in a bed is exposed to such environment continuously. If people are continuously exposed to such environment, the possibility of respiratory diseases such as skin diseases such as atopy and asthma is increased.

Meanwhile, as the hazards of new products such as VOCs, especially formaldehyde, are becoming known, more and more people are using air purifiers. However, since the air purifier sucks the air into the housing and discharges the purified air upward, the VOC concentration in the space is lowered, and the VOC in the air directly contacted by the person lying in the bed is removed Because it is not giving, its utility is limited. In addition, an air purifier composed of such a separate product occupies a large portion of the indoor space.

On the other hand, the method of removing VOC from the circulating air purifier mainly uses an adsorption method such as activated carbon or a plasma ionizer method. However, since the adsorption type filter such as activated carbon has a short replacement period and can not be regenerated, And Plasma Ionizer has VOC removal efficiency, but it is not effective enough to remove VOC from new house or new furniture to appropriate level.

Accordingly, there is a need to provide fresh air from which VOC is removed to a person in bed, and to provide an air purifier that does not require replacement of the filter and has high VOC removal efficiency.

Also, when providing fresh air directly to a person, it is necessary to provide air having a temperature at which a person can breathe most comfortably when sleeping.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to inform.

Fig. 1 is a perspective view of a bed provided with an air purifier according to the present invention, Fig. 2 is a side view of the bed of Fig. 1, Fig. 3 is a bottom view of the bed of Fig. 5 is a perspective view showing another embodiment of the pillars of the bed of FIG.

The bed to which the air purifier of the present invention is applied includes a body frame 10 on which a bedding such as a mattress is placed and a pillar 12 which is a bridge for separating the body frame from the floor by a predetermined distance. In the embodiment of the present invention, there is exemplified a baby bed in which a railing is formed to prevent an infant from being turned over and falling down under the bed. However, the present invention is not necessarily applied to a baby bed, and various modifications may be made depending on the shape of the bed.

The hollow portion 12 is formed at least in a part of the hollow space with an empty space. The hollow space communicates with the discharge port 16 formed above the body frame. The outlet 16 is located at a height corresponding to the height of the person lying on the bed. The discharge port 16 is viewed sideways, and the air that has been flowed by a fan to be described later is discharged laterally through the discharge port.

The portion of the column portion where the discharge port 16 is formed is rotatably provided with respect to the other portion of the column portion so that the user can adjust the discharge direction of the purified air by rotating the column portion formed with the discharge port 16. For example, as shown by an arrow in FIG. 1, if the direction in which the air is discharged is adjusted in the direction of wrapping the bed, the air is discharged to function as an air curtain which isolates the space inside the bed from the space outside the bed.

As shown in FIG. 4, it is also possible to apply a method of adjusting the direction of air by providing a blade 16 rotatably installed on the discharge port 16, and by closing the blades to close the discharge port, It is also possible to prevent the air from being discharged from the discharge port 12. It also allows the blade to automatically rotate so that the direction in which the exhausted air is discharged changes continuously.

As shown in Fig. 5, the portion of the column 12 where the discharge port 16 is formed may be composed of a plurality of divided columns 14. Each of the dividing pillars 14 is formed with a respective discharge port 16, and these dividing pillars 14 can rotate independently of each other with respect to the pillars 12, so that the direction of the discharge port can be adjusted. When the divided pillars 14 are formed in the pillars, the air discharged from the discharge port 16 of some divided pillars functions as an air curtain. The air discharged from the discharge port of the other pillars is directly supplied to the person in the bed .

Referring to FIGS. 2 and 3, a fan 40 is installed at the center of the bottom of the body frame 10. The fan 40 sucks outside air through the inflow part 43 formed in the fan housing 41 and discharges the air to the discharge part 46. The hollow space of the discharge portion 46 and the above-mentioned column portion 12 is communicated with each other through the duct 50. Therefore, the air pressurized and discharged by the fan 40 in the discharge portion 46 is discharged to the discharge port 16 through the hollow space of the column portion 12 along the air flow path formed by the duct 50 . That is, the air flows in turn through the inlet 43, the inner space of the fan housing 41, the outlet 46, the duct 50, the post 12, and the outlet 16.

A pre-filter 44 is provided in the inlet 43 to filter the dust mixed in the air sucked into the fan housing 41 by the fan 40. The prefilter is detachably installed to facilitate cleaning and maintenance of the prefilter. Of course, other filters for filtering dust, such as HEPA filters, may also be used.

The rotary type fan 40 discharges pressurized and accelerated air to a plurality of (four in the present embodiment) discharge portions 46 formed along the periphery of the fan housing 41.

The air purifier and the air conditioner of the present invention, or modules thereof, are installed in the air flow path. That is, the module can be installed in the inner space of the fan housing 41, the inner space of the duct 50, the hollow space of the column 12, and the like.

6 is a cross-sectional view showing an embodiment of a photocatalyst-air purification module of a bed air purifier according to the present invention. The photocatalyst-air purifying module 3 shown in FIG. 6 may be integrated with the fan 40 shown in FIGS. 2 and 3.

An air inlet 43 is formed at the bottom of the fan housing 41. The air inlet 43 is covered with a pre-filter 44. The fan 40 is rotated in the inner space of the fan housing 41. [ A thermoelectric element 80 for supplying heat or supplying cool air for air conditioning is installed on the upper part of the inner space of the fan housing 41 and a pin 81 for heat radiation or heat absorption is provided on the bottom surface of the heat generation and heat absorption part, Respectively. The thermoelectric element 80 may be, for example, a Peltier element capable of adjusting heat absorption and heat radiation according to the direction of current. A temperature sensor may be provided at a predetermined position of the bed, and the control unit determines whether the Peltier device should absorb heat or generate heat according to the room temperature sensed by the temperature sensor, and supplies a proper current and a positive current to the Peltier device .

On the other hand, the surface of the fan 40, more specifically, the surface of the wing of the fan facing the bottom, is coated with the photocatalyst material 63. The LED 70 for irradiating light for activating the photocatalyst material 63 may be mounted on the substrate 71 and installed on a rib 42 (see FIG. 3) formed on the inflow portion 43 side of the fan have.

The photocatalyst material 63 is TiO ₂ , and the LED 70 irradiates ultraviolet rays upward to activate the photocatalytic reaction of the photocatalyst material. The ultraviolet rays emitted from LEDs are configured to have a peak wavelength at 340 to 380 nm.

It is known that the ultraviolet absorption rate of TiO ₂ photocatalyst material according to ultraviolet wavelength absorbs the wavelength near 270 nm and linearly decreases toward 400 nm. However, when the actual UV LED was used, it was confirmed that the UV LED having the peak wavelength activated at the highest photocatalytic efficiency was 365 nm. This is because of the luminous efficiency of the UV LED. Since the light emission amount of the UV LED with a small peak wavelength is sharply decreased, the UV LED having a low peak wavelength is used to adjust the required ultraviolet intensity at the surface of the photocatalytic filter. However, there is a limit to increase the size of the substrate for the air flow, and the cost itself increases sharply. As a result, it was confirmed that the deodorization efficiency by the photocatalytic filter was drastically decreased when UV LED having a peak wavelength of 340 nm or less was used.

In addition, when the UV LED having a peak wavelength of 380 nm or more is used, the ultraviolet ray absorption rate of the photocatalyst itself is small and there is no difference from using the conventional ultraviolet light source lamp.

Experimental results show that UV LED with peak wavelength of 360nm or more and 370nm or less can maximize deodorization performance by the photocatalytic filter.

On the other hand, the photocatalyst material may be coated on the surface of the fin (81). When the fan 40 rotates, the light irradiated from the LED is irradiated on the blade of the fan and is repeatedly irradiated onto the pins of the thermoelectric element. Therefore, in the present invention, in order to increase the efficiency of the photocatalytic reaction, the photocatalyst material is coated on the surface of the fin which has a large surface area in contact with the air for heat transfer efficiency as well as the blade portion of the fan, It is a technical feature that the reaction efficiency is remarkably increased.

6 illustrates an example in which the LED is installed below and the thermoelectric element is installed on the upper side. Conversely, the thermoelectric element may be located at the lower side, the LED may be located at the upper side, and the thermoelectric element or LED may be located at the outlet side. That is, the configuration related to the photocatalytic filter or the configuration related to air conditioning may be changed as needed.

FIG. 7 is an exploded perspective view showing another embodiment of the photocatalytic-air cleaning module of the air purifier for bed according to the present invention, FIG. 8 is a perspective view of the module shown in FIG. 7, and FIG. 9 is a sectional view of the module of FIG.

The photocatalyst-air purification module 3 may be installed in a space having the shape of the duct 50 as shown in the figure. A thermoelectric element 80 is provided in the duct 50 and a pin 81 is provided on the thermoelectric element 80 for heat absorption or heat dissipation. The pins 81 shown in Figs. 7 to 9 are shared by the thermoelectric elements 80 attached to the upper and lower portions, respectively.

The fin (81) has a honeycomb shape in which a plurality of air holes (62) formed along the flow direction of air are arranged side by side and is made of a material having high thermal conductivity. In the embodiment of the present invention, one of the features of this pin 81 is that the function of the photocatalytic filter is together. In other words, the honeycomb-shaped pins 81 function as the base body 61 of the photocatalytic filter, and TiO _{2, which} is the photocatalyst material 63, is coated on the base body 61.

Since the photocatalytic filter 60 has a cross-sectional shape corresponding to the cross-sectional shape of the air flow path formed in the duct 50 together with the thermoelectric element 80, when they are installed in the duct, And flows through the vent hole 62 of the photocatalytic filter.

A substrate 71 on which the LED 70 is mounted is provided on the upstream side of the air flow path of the photocatalytic filter 60 as well as the pin 81. The substrate 71 is fitted in the fixing portion 92 formed at one end of the bracket 90 and is fixed perpendicularly to the air flow direction.

The fitting portion 91 formed at the other end of the bracket 90 is inserted into the groove 411 formed in the housing of the fan 40 and fixed to the inner wall of the duct 50 to thereby be fixed inside the duct 50. That is, since the cross-section of the housing of the fan coincides with the cross-sectional shape of the flow path formed by the inner surface of the duct, when the fan is inserted into the duct, the fan and the LED are fixed together in the duct. According to this structure, the LEDs can be installed together while the fan 40 is installed, thereby facilitating assembly of the module.

Referring to FIG. 9, when the fan flows air in the right direction in the drawing, air passes through the photocatalytic filter and the fin, and the VOC is decomposed and the air is adjusted to an appropriate temperature. At this time, the light irradiation direction of the LED and the flow direction of the air coincide with each other. This structure makes the photocatalytic reaction from the front surface of the photocatalytic filter occur before the pressure drop of the air passes through the photocatalytic filter, thereby further enhancing the decomposition efficiency of the harmful gas of the photocatalytic filter.

The photocatalyst-air conditioning module 3 may be installed in the duct 50. In addition, although the fan 40 is installed in the module shown in FIGS. 7 to 9, when the air purifier is installed with one common fan as shown in FIGS. 2 to 3, the module is installed in the duct of the module The fan is optional.

FIG. 10 is a perspective view showing another embodiment of the photocatalytic-air cleaning module of the air purifier for bed according to the present invention, and FIG. 11 is a sectional view of FIG.

In the embodiment shown in Figs. 10 and 11, the LED 70 and the substrate 71 are provided on the inner wall surface of the duct, the thermoelectric element 80 and the pin 81 are provided on the opposing inner wall surface, A photocatalyst material is coated on the surface of the substrate 81. A pin 81 having a large surface cross-sectional area faces the LED 70. Therefore, the light emitted from the LED 70 is irradiated to the photocatalyst material 63 coated on the surface of the fin 81 to activate the photocatalytic reaction.

The photocatalyst-air conditioning module 3 may be installed in the duct 50. In the modules shown in Figs. 10 and 11, the fan 40 is installed. However, when the air purifier is implemented with one common fan installed as shown in Figs. 2 to 3, Can be omitted.

12 is a cross-sectional view showing another embodiment of the photocatalyst-air purification module of the air purifier for bed according to the present invention.

The photocatalytic-air purifying module 3 shown in FIG. 12 is provided inside the duct 50, and has a configuration for leading a photocatalytic reaction and a module for leading air conditioning. A photocatalytic filter 60 in which TiO ₂ as a photocatalyst material 63 is coated on a honeycomb substrate 61 in which a plurality of ventilation holes 62 are formed in parallel with the direction of air flow, And an LED 70 for irradiating the filter 60 with ultraviolet rays.

More specifically, the photocatalytic filter 60 has a honeycomb structure in which a plurality of square ventilation holes 62 are arranged side by side. The shape of the ventilation holes is not limited to a square shape but may be formed in various shapes such as a regular hexagon . This can be manufactured by immersing the above-mentioned honeycomb base in a dispersion of TiO _{2 as} a photocatalyst material, coating, drying and sintering.

The honeycomb shaped body can be made of a porous ceramic. The TiO ₂ dispersion is well entangled in the porous interior and is fixed to the ceramic surface. In this state, when the sintering is performed at a temperature of 300 to 500 ° C. for 1 to 3 hours, the TiO ₂ is completely fixed to the surface of the gas. If the sintering temperature is less than 300 ° C or less than 1 hour, the sintering does not proceed properly. If the sintering temperature exceeds 500 ° C, the TiO ₂ is denatured and the function as a photocatalyst material is largely lost. Therefore, when the sintering is performed at a temperature of 300 to 500 ° C for about 3 hours, the photocatalyst material is completely fixed to the surface of the substrate.

The photocatalytic filter of the present invention in which the photocatalyst material is firmly adhered can maintain the state that TiO ₂ is not dissolved in water but is fixed to the photocatalytic filter even if it is put into boiling water. Experimental results show that the photocatalytic reaction is recovered by 90% or more of the new product when the photocatalytic filter, which has been contaminated by dust and the like, has lost much of its photocatalytic activity and is regenerated in boiling water.

The photocatalyst-air purifying module 3 may be configured to lead air purification by using the thermoelectric element 80 described in the other embodiments and the pin 81 attached thereto.

In the photocatalyst-air cleaning module shown in FIG. 12, the fan is omitted. The fan may be implemented in a form in which one common fan is installed as shown in FIGS. This fan may also be installed in the hollow space of the post close to the outlet 16 of each post 12 to enhance the air curtain function.

Hereinafter, the operation of the bed air purifier of the present invention will be described.

The user goes to bed and operates the photocatalyst-air conditioning module 3. Then, the control unit of the air purifier calculates the amount of heat or heat absorbed by the thermoelectric element 80 based on the temperature measured by the temperature sensor, and supplies power to the thermoelectric element 80. In addition, the fan rotates to form an air flow, and the LED is turned on to activate the photocatalytic reaction.

Then, the harmful gas such as VOC is decomposed and purified by the photocatalytic reaction, and the air in contact with the fin is heat-exchanged with the pin and adjusted to a proper temperature. The air is discharged through the outlet in this state. At this time, the user can adjust the direction of the blade of the discharge port, or rotate the column or the divided column to adjust the discharge direction of the air to a desired direction or automatically change the wind direction. The user who has finished sleeping while the air cleaner is operating can turn off the air cleaner.

From a maintenance standpoint, the user can remove and clean the prefilter 44 at regular intervals. Also, the photocatalytic filter can be regenerated and re-installed by removing it once every 1 to 2 years.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments. It is obvious that a transformation can be made. Although the embodiments of the present invention have been described in detail above, the effects of the present invention are not explicitly described and described, but it is needless to say that the effects that can be predicted by the configurations should also be recognized.
