Description

A ventilated mattress and a bed comprising a ventilated mattress

The present invention relates to a mattress with improved ventilation performance and a bed including the mattress.

A bed provides comfort and comfort when sleeping, and is generally composed of a bed frame and a mattress.

In a general mattress, the temperature is maintained according to the bedroom temperature when the user sleeps. In summer, the temperature of the bedroom will be high, so the temperature of the mattress will increase, and in winter, the temperature of the mattress will decrease.

That is, in summer, the temperature of the mattress increases, so that the user feels heat, and in winter, it feels cold. In order to solve this problem, a cool mat providing a feeling of cooling to the user in summer and a heating mat and an electric heating mat providing a feeling of warmth to the user in winter have been installed on the upper part of the mattress.

When a cool mat or a heating mat is installed and used on the upper part of the mattress, the user's body comes into contact with the cool mat or the heating mat rather than the mattress. Accordingly, there is a disadvantage in that the comfort and comfort provided by the mattress itself is reduced.

On the other hand, Japanese Patent Document No. 5960669 discloses that a blower is installed in a bed frame on which a mattress is placed, without installing a configuration such as a cool mat or a heating mat on the upper part of the mattress, and selectively heating or cooling the air transported by the blower. We present an air-conditioning bed equipped with a temperature control device for According to the above document, it is possible to provide a feeling of coolness or warmth to the user regardless of the temperature of the bedroom, while providing the comfort and comfort of the mattress itself. However, air leaked through the side of the mattress before the air transported by the blower passes through the mattress and is delivered to the user, so the amount of air actually delivered to the user is not large.

In order to solve the above disadvantages, Korean Patent Document No. 10-1913785 proposes a configuration in which a floor made of a non-breathable material is installed on the side of the mattress so that the air transferred from the blower is discharged only through the ventilation part. However, this also has a problem in that a sufficient amount of air is not transmitted enough to be recognized by the user.

Accordingly, while maintaining the comfort and comfort provided by the mattress, there is a growing need for a ventilation mattress and bed in which a sufficient amount of air can be discharged from the surface of the mattress to be felt by the user.

When the flow path switching member 351 is in contact with the left inner surface or the right inner surface of the first connecting portion 341a, corresponding to the position where the connecting portion 341 is in contact (the second discharge passage when in contact with the left inner surface, the right inner surface) When in contact with the first discharge passage), it communicates only with the discharge passage. And, as the flow path switching member 351 is configured with the above-described length, the outdoor air discharged from the outlet 312 may be discharged only through the discharge passage communicating with the connection part 341 without a problem of leaking to another discharge passage. there will be

The driving member 352 is connected to the flow path switching member 351 and is configured to provide a driving force for rotation of the flow path switching member 351 . For example, it may be a motor, and the flow path changing member 351 can rotate by using a portion connected to the driving member 352 as a rotation axis.

The heater 360 is installed at the rear end of the flow path switching unit 350 and is configured to heat the outside air passing through the heater 360 . The heater 360 includes a first heater 361 provided on the side of the first discharge passage 342 and a second heater provided on the side of the second discharge passage 343 and operable independently of the first heater 361 ( 362).

As the first heater 361 and the second heater 362 are independently operable, various modes may be implemented.

In the state in which the connection part 341 is connected to both the first discharge passage 342 and the second discharge passage 343, the heating operation of any one heater is stopped so that only the outside passing through any one discharge passage is heated, and , the heating operation of the other heater is activated, it is also possible to provide heated outdoor air only to any one of the left or right portion of the mattress 100. In addition, in a state in which the connection part 341 communicates with only one discharge passage, unheated outdoor air or heated outdoor air may be discharged to the outside of the mattress 100 through the heating operation on/off of the heater located in the corresponding discharge passage. have.

The input unit 370 is configured to input an operation command to selectively blow at least one of the blowing temperature of the outside air discharged from the blower 300, the left part and the right part of the mattress 100. The input unit 370 may be provided, for example, in the form of a touch panel, or may be provided in the form of a plurality of input buttons.

The control unit 380 is installed on the body 310 and is configured to control the operation of the blower 300 (operation of the blower, operation of the heater, operation of the driving member, etc.) according to the operation command input to the input unit 370 . do.

An operation of the driving member 352 by the controller 380 will be described in detail with reference to FIGS. 8 to 10 .

A first position recognizing unit 353 is installed in the flow path switching member 351 , and a distance between both outer surfaces of the first connecting unit 341a and the first position recognizing unit 353 on the upper or lower surface is a predetermined distance. If it is less than, the second position recognition unit 344 that is activated to generate an electric signal is installed.

It is assumed that a command is input to the input unit 370 to blow air only through the first discharge passage 342 . The controller 380 controls the blower 320 to operate, and controls the driving member 352 so that the flow path switching member 351 is in contact with the left inner surface of the first connection part 341a. At this time, the control unit 380 rotates the flow path switching member 351 until an electric signal is generated from the second position recognition unit 344 installed on the left inner surface of the first connection unit 341a. The generation of an electric signal from the second position recognition unit 344 installed on the left inner surface of the first connection unit 341a means that the first position recognition unit 353 and the second position recognition unit 351 of the flow path switching member 351 ( 344) refers to a state in which the distance is less than a preset distance (more specifically, a state in which the first position recognition unit and the second position recognition unit are in contact with each other). Through this, it is possible to rotate the flow path switching member 351 to a position corresponding thereto according to a command input to the input unit 370 .

validation experiment

An experiment was conducted to verify the superiority of the ventilation performance of the bed according to the present invention.

i) the mattress 100 according to the present invention in which the blower 300 is installed, and ii) in the conventional mattress, while varying the rotational speed of the blower for supplying outdoor air to the mattress, the mattress 100 according to the present invention is toppered (a) the upper part of the topper 200 in a state combined with (a), and (b) the upper part of the mattress 100 in a state in which the mattress 100 is separated from the topper 200 using a measuring instrument for measuring the wind speed An experiment was performed to measure the speed of external air delivered to an actual user.

As shown in FIG. 11 , the wind speed was measured at 20 locations (4x5) in the upper part of the mattress 100 or the upper part of the topper 200, respectively, and the same results as in FIG. 12 were obtained.

As a result of the experiment, in the conventional mattress, the air transferred from the blower device leaked through the side of the mattress before being delivered to the upper surface of the mattress or due to air resistance, valid data was not measured by a meter located on the upper part of the mattress.

That is, in the conventional mattress structure, even if the outdoor air is provided through a blower in the lower part of the mattress, the outdoor air is not discharged enough to be recognized by the user on the upper part of the mattress.

On the other hand, in the bed according to the present invention, even if the blower 320 rotates at a speed of 280 RPM, it has an average speed of 1.57 m/s at 20 locations and it was possible to obtain the result that the outside air is discharged, and the topper on the top of the mattress 100 (200), it was possible to obtain the result that the outside air was discharged with an average speed of 0.06 m/s.

Meanwhile, the American Society for Air Conditioning and Air Conditioning (ASHRAE) defines wind with a speed of 0.15 m/s or less as still air.

According to the present invention, even when the blower 320 is rotated at a low speed, it was confirmed that the outside air is discharged with a speed exceeding 0.15 m/s on the upper part of the mattress 100, and the topper 200 on the upper part of the mattress 100 ), when the blower 320 is rotated at a high speed (eg, 590 RPM), it has a speed exceeding 0.15 m/s, and it was confirmed that outdoor air is discharged.

As a result of the experiment, in the conventional mattress structure, it was confirmed that the air transferred from the blower leaked to the outside even before it was transferred to the upper part of the mattress, or the air transferred to the user lying on the top of the mattress could not be transferred due to air resistance.

In addition, in the mattress 100 structure according to the present invention, it was confirmed that the air transferred from the blower is delivered with a speed that is fast enough to be recognized by the user lying on the mattress 100, and furthermore, the topper ( 200), it was confirmed that the topper 200 had a high speed enough to be recognized by the user lying on the upper part and the air was delivered.
