Figure 16 and Figure 17 illustrates a knee hook cushion that can be added to the present invention.

The present invention combines a heat transfer configuration and hot and cold air supply with a bed or bed mattress.

Mattresses (hereinafter referred to as beds) for beds and beds made of general cushions and covers only have no insulated or insulated functions per se, and therefore, efforts have been made to add insulated or insulated functions since ancient times.

For example, ordinary electric wire was laid on the bed and used in the cold winter, but in this case, the electric wire was deformed along the soft cushion of the bed, causing damage to the heating wire. Laying ondol beds have been developed.

However, the ondol bed has a merit that the heating wire is protected and has the same effect as the ondol room, but the floor is too hard to satisfy all users.

In addition, when adding a heating mat with a heating wire embedded in a bed cushion above a certain depth, the cushioning can be maintained in addition to the heating wire protection, but in order to heat up the surface of the bed cushion, there was a drawback of severe power consumption of the heating wire.

Therefore, among the recently developed beds, a method of supplying warm air into the bed cushion so that the warm air rises on the cushion surface on which the user is lying has appeared.

However, in the case of the warm air supply bed, there was a problem in that a separate powerful warm air supply was installed on the outside, and there was a method in which a small hot air supply was sometimes attached to the outside wall of the bed, but this also warmed the entire bed cushion inside. There was a difficult problem to heat only.

The present invention for solving the above problems is to minimize the electric energy required to generate warm air by using a structure for heating only the air circulating therein, not to heat the outside open air.

In addition, the main purpose of the invention is to arrange a plurality of heat transfer pieces that can effectively transfer heat to the bed surface to make the most of the heat energy of the cold and hot air.

First, the present invention starts from the following technical concept.

Looking at a typical hot air bed, the warm air by supplying the warm air inside the cushion of the bed has a number of advantages, such as dehumidification and comfortable effects due to ventilation, but energy efficiency compared to the electric heating method using a conventional heating wire In terms of differences, there is no big difference or rather a little behind.

Because not only does it take a lot of heat energy to heat the outside air with hot air in a short time, but the electric heating method only needs to warm the surface of the bed, but the warm air method only warms the entire inside of the bed cushion to warm the surface. to be.

Considering the additional blowing energy required here, the conventional bed heating method by the warm air is not very advantageous in terms of energy efficiency.

However, considering the unique structure of the bed, there are places where a heating device and a flow rate supply device can be disposed inside.

That's where the user's feet are.The bed cushions that support the head to hips of the person sleeping / resting in bed are the places where relatively heavy loads are applied, Not much load is applied.

Therefore, even if a device for inhibiting a cushioning feeling such as a heating / airflow supply device is inserted into this portion, the user's satisfaction is hardly degraded during the sleep / resting process.

When the heating / airflow supply device is inserted into the bed as described above and the inside of the bed is almost blocked from the outside, the amount of energy required to heat or circulate the limited air therein is dramatically reduced.

Here, there is a fear that a large number of heating air will escape between the upper fabric of the cushion of the bed.

Of course, the escape of the air inside the bed to the top of the bed is inherent in most hot air beds aimed at ventilation and dehumidification.However, if the internal heating air is easily exhausted, in order to keep the bed cushion surface at an appropriate temperature There is still a great deal of exothermic energy.

In order to solve the above conflicting problems, a method of arranging and fixing a plurality of heat transfer pieces inside the surface on the bed (upper side of the cushion) as in the present invention can be considered.

Such a heat transfer piece easily absorbs the heat energy of the heating air having a small amount of air and intensively transfers it to the surface of the bed, so it is combined with the heating and air supply device built in the foot of the bed mentioned above, and has a significant synergistic effect. Occurs.

In addition, by dividing the heat transfer piece into a plurality of pieces to be wrapped in a fixing cloth and secured by sewn, etc., the ventilation effect between the heat transfer pieces is maintained almost the same, rather, the ventilation effect is increased and the user is still when the user turns over the body. When you are lying down or leaving the bed, you also have a great effect of minimizing the release of unnecessary heat.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings in order to represent the technical features of the present invention in more detail. However, specific embodiments of the present invention or specific examples included in the drawings are included in the present invention. It does not limit the technical idea inferred.

1 to 2 show a conventional warm air mattress.

In the figure, a hot air supply pipe 3 is connected to one corner of the mattress 1, and a hot air supply device 2 is connected to a distal end of the hot air supply pipe.

The warm air generated by the warm air connecting device is introduced into the mattress 1 along the supply pipe 3 and discharged to the vent 11.

In this process, the surface of the mattress 1 may be a non-ventilated material such as vinyl, but since it is usually made of a ventilated material such as cloth, the warm air is not necessarily discharged only to the vent 11, but to the entire surface of the mattress. The warm air will escape.

The vent may, of course, be of a special through construction, or it may be a natural knot produced by sewing a cushion on the mattress.

2 shows an internal duct configuration (parts indicated by dashed lines) for sending warm air to the ventilation holes 11, in which case the warm air is not evenly discharged to the entire mattress and is discharged along a specific duct.

3 is a view showing the hot air supply device 2 of FIGS. 1 and 2 in more detail.

In the drawing, the warm air supply device connected to the external power source has a blower fan 22 and a heating coil 21 formed therein, and the air supplied from the blower fan is heated while passing through the heating coil.

Figure 4 is an internal perspective view showing an embodiment of a warm air bed of the present invention.

The bed 1 shown in the drawing comprises a mattress, a rim cushion surrounding the mattress, and a base supporting the mattress, wherein the rim cushion is divided into at least two parts in the longitudinal direction of the mattress. Can lose.

And the rim cushion portion located on the foot side of the user of the movable knee hook cushion 16 and the knee hook cushion movable portion of the movable boom (Boom) form consisting of a cylinder and a piston inserted into the knee hook cushion 16 ) Is further configured.

The mattress includes a main body having a spring cushion 15 and surrounded by a ventilated outer shell 12, an internal air suction port 31 disposed on a bedside of the bed inside the main body, and a lower neck of the bed within the main body. A plurality of heat transfer pieces arranged at an upper portion of the main body and a duct connecting the air flow rate supply device 30, the internal air suction port 31, and the air flow rate supply device 30 disposed in a portion; It is configured to include.

Above the duct may consist of a flexible hose (similar to the suction hose of a vacuum cleaner) placed between the spring cushions.

On the other hand, the heat transfer piece 13 attached to the bottom of the shell 12 is formed in a flat plate shape of a metal or non-metal material, and is fixed by a cloth-covered cloth and disposed inside the upper surface of the main body.

At this time, the size of the heat transfer piece is 1 to 6cm in width, 2 to 12cm in width, the thickness is determined in the range of 1 to 15mm, in particular may be composed of aluminum or aluminum alloy material.

Preferably it may be made of an aluminum piece of 2.5 to 3 cm in length and 3.5 to 5 cm in thickness of about 3 to 5 mm.

On the other hand, the body of the mattress is further formed with a cover portion 18 for mounting or removing the air flow rate supply device or the duct or the air suction port on the side of the side where the air flow rate supply device is located, the cover portion from the outside inside the main body External air inlet for introducing air into the furnace may be further provided.

The bed of Figure 4 configured as described above, the outer air inlet cover 17 of the cover portion 18 is in a closed state and a small volume of air in a narrow space inside the mattress is introduced through the internal air inlet 31, The duct 33 is supplied to the heating device and the air flow rate supply device 30.

The air discharged through the left and right air flow rate supply device is hot air heated through the heating coil 39 of the heating device 34 and moves back to the bedside (air intake side) of the bed.

In other words, the head of a person lying in bed is relatively cold, and the foot is relatively warm, and air is slowly circulated inside.

Such an air circulation mechanism is very exquisite ergonomically, even in the cold winter, a person feels frustrated during sleep when the head is too hot. In the embodiment of the present invention, the foot is warmer and relatively relatively. The head is cool, so even if the circulation is strong and continuously, the person lying in bed can sleep warmly in a comfortable state.

Since the air inlet 31 is a relatively small component, it does not affect the entire cushion of the bed. The duct 33 is flexible and easily inserted between the springs, so that the mattress can be easily folded in half.

On the other hand, the heating device and the airflow supply device which occupy a relatively large volume can make the user feel the foreign body of the cushion inside the bed, but this inconvenience is minimized because the load is hardly applied even when the body is located on the foot.

In the drawing, the flow of air 100 flows from the foot to the head as a whole, and the heating material may leak slightly because the mattress material is not a complete sealing material, but it corresponds to a small amount of leakage compared to the total heating amount. This small leakage air causes a ventilation effect on the seat surface of the mattress is a major factor to make the user feel comfortable.

In addition, since the heating device and the air volume supply device only need to circulate the internal circulating air, only a small amount of power is required, which is incomparable with the warm air supply device as shown in FIGS. 1 to 3.

Since it can be equipped with a low noise fan and a low heat generation heating wire, it plays a decisive role in getting a good night's sleep with extremely low power consumption and extremely quiet operation.

5 is a state in which the external air inlet 16 is open in the configuration of FIG.

In the drawing, the heating device is in a stopped state and shows a state in which the fresh air supply device sucks the fresh air outside and discharges it toward the internal air suction port 31.

This state of use occurs mainly in the summer, where the seat surface of the mattress is hot and sticky.

At this time, if the inlet of the outside air as described above, unlike the state in which a constant amount of air is not circulated only in the interior, and the outside air is continuously flowing into the mattress, the inlet-discharge must be discharged to the upper surface of the mattress to achieve an equilibrium do.

Reference numeral 100 indicates the discharge air flow to the upper surface of the mattress as described above.

In this case, the heat transfer piece 13 located on the mat upper surface serves as an excellent cooling fin that receives the hot heat from the upper surface of the mat and delivers the heat toward the outside air.

6 and 7 is an external perspective view showing an embodiment of a heating apparatus and a flow rate supply apparatus that can be applied to the present invention.

In FIG. 6, the air flow rate supply device 30 has an axial fan mounted therein, one side of which is connected to the heating coil 31, and the other of which is connected to the duct 33.

The air volume supply device has a temperature detecting unit 37 for detecting the air temperature before entering the heating coil and a removable fragrance 36 for adding flavors to the external air flowing from the duct 38 connected to the external air inlet. It may be further provided.

In other words, the temperature sensing unit 37 is a device utilized in the heating mode of the internal circulation air, and the removable fragrance 36 is a device utilized in the blowing mode of the external inlet air.

On the other hand, the air discharge duct 32 in the air volume supply device may be provided with an external air inlet duct 38 and the air discharge duct cover 35, if the air discharge duct when used in the internal circulation heating air method in winter The cover 35 is opened and used, and the external air inlet duct 38 must be kept closed.

On the contrary, when the air inlet duct is used in the summer, the air discharge duct cover 38 is closed and the external air inlet duct 38 must be used in an open state.

FIG. 7 illustrates another embodiment of the present invention in which the air is blown directly from the bottom of the mattress without using the inner duct 33 in the external inflow blowing method of FIG. 6.

In FIG. 7, the airflow rate supply device 42 sucks air from the outside and directly discharges the air 100 into the mattress by the centrifugal fan 43 provided on the left and right sides.

In this case, as shown in FIG. 6, neither the heating device nor the axial fan mounting air flow rate supply device is used.

All of the above series of devices can be mounted or removed by the cover 18 provided on the mattress side.

8 is a view illustrating an embodiment of the present invention described in FIG. 4 in stages of air flow. The internal air is introduced into the internal air intake port (S1) and is introduced into the heating device from the airflow supply device through the duct (S2). ), And is heated in the heating apparatus (S3) and discharged through the air discharge duct 32 (S4).

At this time, the hot air 100 flows slowly from the user's foot toward the head.

FIG. 9 is a diagram showing that the apparatus shown in FIG. 8 may be arranged in plural numbers. If the apparatus is arranged in plural numbers, the inlet-duct-heating and discharging apparatuses may be further miniaturized, thereby enabling extremely quiet operation.

FIG. 10 shows another embodiment of the present invention modified from FIG. 8.

Referring to the drawings, the airflow rate supply device for introducing air from the outside of the mattress immediately discharges the air flowing from the external air inlet, which may be provided with a centrifugal fan on the left and right. In this case, the blowing efficiency is improved, and the duct and the heating device and the axial fan type air flow rate supply device (shown in the dotted line in the drawing) which are not used in summer can be removed and stored hygienically.

11 and 12 are views showing the configuration and operation of the storage cloth 14 which is one of the core configuration of the present invention.

In FIG. 11, the air 100 flowing inside the mattress is usually discharged only slightly through the storage cloth 14 and the sheet surface 12 between the heat transfer pieces 13.

The storage fabric 14 is separated from the drawing, but sometimes it may be constructed by laying a heat transfer piece on one large cloth and sewing it with a thread such as a quilt.

Referring to FIG. 12, when the user is lying down, the space between the accommodating cloths 14 may be widened to allow the air 100 to be discharged more easily. If the user flips over in this state, the air will come out easily.

This is a technically important meaning, as the user sweats on his back and feels uncomfortable, the number of times he or she turns over becomes more frequent.In this case, the amount of discharged air is increased to improve the air permeability of the seat surface, and in other cases (for example, when the user quietly In the case of sleeping while lying down, the amount of discharged air is reduced and only a smaller amount of power is required to keep the internal air warm, and the fan of the air volume supply device may run weaker (quietly).

13 to 15 are side views of the mattress showing the action of the heat transfer piece 13 which is one of the core configuration of the present invention.

In the case of intake-heating-discharging the internal air as shown in FIG. 13, the heat transfer piece 13 absorbs the heat of the internal air 100 and transmits heat to the sheet surface in the form of heat conduction (surface contact transfer) (102). do.

At this time, if the user flips over the body, some warm air is selectively discharged.

In the case of internal air intake, non-heating, and discharge, as shown in FIG. 14, the heat transfer piece 13 transmits the cool and dry energy of the interior to the seat surface 103. This includes the effect of dehumidification.

In addition, in the case of FIG. 14, the fragrance component may be added to the discharged air from the perfume 36.

In the case of intake-discharge of external air as shown in FIG. 15, the overall similarity to that of FIG. 14 is used, but in this case, other devices inside other than the inlet and outlet of the external air are not used. The amount of air discharged is greatly increased.

At this time, as in FIG. 14, the heat transfer piece 13 transmits the cool and dry energy inside to the seat surface 103. This includes the effect of dehumidification.

16 and 17 show the knee cushion 16 that can be added to the embodiment of the present invention including all of the above configuration, the knee cushion is a border cushion portion 60 disposed on the left and right of the bed It can be made by dividing a part and ascended / rotated by the movable boom 61 as shown in FIG. 16 and placed on the bed sheet surface 12.

In other words, the rim cushion portion is divided into two or three in the longitudinal direction of the bed, of which the movable cushion boom 61 is built in the rim cushion portion located on the user's foot side and the knee hook cushion rotatably coupled will be.

With the above configuration, users can easily rest their legs when they are lying down.

While the embodiments of the present invention have been described in detail with reference to the drawings, the technical idea of the present invention is not limited to the above embodiments, and those skilled in the art to which the present invention pertains, It will be possible to implement embodiments that have been modified or expanded by utilizing the technical spirit contained in the drawings, but this is also clearly included in the scope of the technical spirit uniquely possessed by the present invention.
