Specifically, the controller may lower the target temperature value when the user sensed by the water level sensor is in a non-REM surface level state or a non-REM surface state in a second step.

Specifically, the control unit may maintain the target temperature value when the user's state detected by the water surface sensor is in a non-REM surface level state 3, a non-REM surface state 4, or a REM surface state.

Specifically, the user sensor unit may further include an analysis unit for converting the user's waking time into a database.

Specifically, the control unit may raise the target temperature value when the current time reaches a predetermined time before the user's wakeup time analyzed by the analysis unit.

The mat device according to the present invention analyzes a current sleep state and a pattern of a user's body temperature, ambient temperature, pulse rate, respiration rate, etc. during a sleeping through a sensor unit which can detect vibrations, Thus, a warm and cool feeling can be automatically controlled according to the sleep state and the pattern each time, thereby providing a comfortable sleeping environment.

The heat exchanger 120 may be arranged in order from one side to the other side of the cold panel 1211, the thermoelectric element portion 122, the hot panel 1212 and the fan 1213. In the thermoelectric element portion 122, The surface brought into close contact with the panel 1211 absorbs heat, and the surface brought into close contact with the hot panel 1212 can emit heat. Here, the cold panel 1211 and the hot panel 1212 may be made of a heat sink of a metal material.

For example, when the heat exchanger 120 cools the medium and the mat portion 130 is made of a cool mat, the medium is passed through the medium path 12110 described above to the cold panel 1211. At this time, the heat of the medium may be discharged to the hot panel 1212 through the thermoelectric element portion 122, and the medium may be cooled.

On the other hand, when the mat portion 130 is made of a warm mat, the medium acts in opposition to the heat exchanger 120 for forming a cool mat, and the medium is passed through a passage (not shown) provided in the hot panel 1212 At this time, a fan may be provided on the cold panel 1211 to process cold and cold of the cold panel 1211 so that the cold and hot can be discharged to the outside.

The mat unit 130 can form a sleeping mat that is temperature-controlled to provide a comfortable environment for inducing a comfortable sleep of the user. The mat unit 130 is a medium line through which the medium supplied from the heat exchanger 120 passes, and the channel unit 140 is provided therein to transmit a cool feeling or warmth to the user through the medium.

In other words, the mat unit 130 is provided with a heat medium or cold heat transmitted by a medium spreading in the channel unit 140 to provide comfort through cold feeling in summer, and to provide an environment for a user to sleep from cold through warmth in winter have.

Here, the mat portion 130 prevents the tactile feeling of the material of the channel portion 140 from being transmitted directly to the user, The body is prevented from being exhausted, and the convenience of the user can be improved.

The mat portion 130 may be formed in a sheet shape covering the upper and lower portions of the flow path portion 140. The mat portion 130 may be formed by stacking a plurality of layers such as a nonwoven fabric, The mat portion 130 and the flow path portion 140 may be integrally bonded to each other through a bonding method such as an adhesive.

Alternatively, the flow path unit 140 may be configured to surround the flow path unit 140 so as to surround the flow path unit 140, and the flow path unit 140 may be fixed to the mat unit 130 in a simple manner.

The flow path unit 140 may be provided inside the mat unit 130, and the heated or cooled medium may be introduced and discharged from one side of the mat unit 130 via the other side.

Here, the medium may be circulated through the flow path portion 140 and the medium supply portion 110, as the medium is heated or cooled in the medium supply portion 110, and then is returned to the medium supply portion 110 again.

The flow path portion 140 can be branched into a plurality of paths so that the medium passes easily from one side of the mat portion 130 to the other side via the other side. The branch road may be formed in the form of a net that forms a channel in the longitudinal direction and the transverse direction so that the medium can pass through.

Here, the branching path may be formed through a curved blocking space 141 so as to prevent the flow from stagnating due to a point where the length is branched. The blocking space 141 is formed by a plurality of circles or ellipses Lt; / RTI >

That is, in the case where the flow path is formed in a lattice shape, the curved surface can be formed so as to have no edge so that the medium can be prevented from stagnating at the corner where the flow path is branched.

For example, the blocking space 141 may be filled with a solid material of various materials such as resin between the paths so as to partition the path of the flow path portion 140. Alternatively, the blocking space 141 may be filled with air Modifications are possible.

In order to allow the medium to flow in and out, the channel portion 140 may be formed such that an inlet 142 into which the medium flows from one side of the mat portion 130 and an outlet 143 through which the medium is discharged are adjacent to each other.

The inlet 142 of the flow path portion 140 protrudes toward one side of the mat portion 130 so that the space through which the medium flows can be expanded. At this time, the outlet 143 of the flow path portion 140 is protruded in one direction of the mat portion 130 so as to be symmetrical with the inlet 142, so that the space through which the medium is discharged can be extended.

In other words, when the medium is introduced into the inlet 142 provided at the upper side of the one side, the inlet 142 forms a relatively narrow flow passage as compared with the branching path, The space between the inlet 142 and the branch road may be enlarged so that the medium can be smoothly distributed from the inlet 142 to the branch road.

This allows smooth entry of the medium into the area adjacent to the edge of the mat portion 130, which is apart from the entrance 142 in the horizontal direction, as well as the area opposed to the entrance.

The flow path unit 140 may include a first part 140A and a second part 140B. The area in which the medium flows in and the area to be discharged from the inside of the mat unit 130 are distinguished for the convenience of explanation and understanding . Here, the first part 140A and the second part 140B may be divided in the longitudinal direction of the mat unit 130 and may be provided on the left and right sides.

The first part 140A is separated from the mat part 130 in the longitudinal direction by the entrance part 142 and the exit part 143 is provided on the right side. And the second part 140B may be provided on the right side of the first part 140A on the right side of the mat unit 130. [

That is, the first part 140A may include an entrance 142 at one side of the mat unit 130 and may extend in the longitudinal direction to the other side of the mat unit 130, and the second part 140B may include a first An area from the other side of the mat unit 130 to the outlet 143 which is one side of the mat unit 130 can be formed on the side with respect to the longitudinal direction of the part 140A.

Here, the first part 140A and the second part 140B are separated in the longitudinal direction so as to separate the moving path of the medium from one side of the mat unit 130, and can communicate with each other at the other side of the mat unit 130 .

Alternatively, the first part 140A may be provided across the center along the length of the mat part 130, and the second part 140B may be provided on both the left and right sides of the first part 140A. It is possible.

The sensor unit 150 may sense a peripheral state of the mat unit 130 and a state of the user and may transmit a signal to the controller 160. For example, the sensor unit 150 may include a peripheral sensor unit 151 and a user sensor unit 152.

The peripheral sensor unit 151 may include a temperature sensor 1511 to sense the peripheral condition of the mat unit 130. The temperature sensor 1511 may be provided on the surface of the mat unit 130, It is possible to sense the surface temperature of the mating part 130 which abuts.

The control unit 160 detects the temperature difference between the flow path unit 140 and the mat unit 130 by the temperature sensor 1511 on the flow path unit 140, The temperature of the medium passing through the flow path portion 140 may be controlled in accordance with the surface temperature of the mat portion 130 according to the environmental condition in which the flow path portion 140 is installed.

For example, in the operation of cooling the medium, since a difference in time during which the surface temperature of the mat portion 130 is maintained due to the ambient temperature may occur, such as when the ambient environment is 30 degrees and when the ambient temperature is 25 degrees, 160 may adjust the temperature of the medium passing through the flow path portion 140 so that the surface temperature of the mat portion 130 is maintained in comparison with the surface temperature of the mat portion 130.

The user sensor unit 152 may sense the state of the user. Here, the user sensor unit 152 may include an analysis unit 1522 and a surface sensor 1521, and the analysis unit 1522 may convert the user's weather time into a database.

The sleep sensor 1521 can sense the sleep state of the user, and can distinguish the sleep state of the user into the non-REM surface state and the REM sleep state by using at least one of the body temperature, pulse, respiration, and movement of the user.

Here, the user sensor unit 152 may receive a value such as a user's pulse through a known smart device or the like mounted on the user's wrist.

As is well known, the non-REM level and the REM level state can be classified into one to four levels. The first stage of non-REM sleep is a stage of falling from a wakeful state to a real sleep state, crossing the boundary between sleep and consciousness, and the second stage of non-REM sleep is a real sleep or light sleep, Sleep. Non-REM Level 3 to 4 stages can be defined as Slow wave sleep, in which slow and large amplitude EEGs are recorded. And the level of REM sleep can be defined as sleep when the brain waves are awake, but the skeletal muscle is less relaxed.

The control unit 160 can receive the input by the user or can correct the target temperature value of the predetermined medium according to the user's state or the surrounding state of the mat unit 130. The control unit 160 controls the temperature sensor 1511 The target temperature value can be corrected when the detected temperature is less than the reference value.

When the temperature sensed by the temperature sensor 1511 is less than the reference value, it may mean winter, and the controller 160 may raise the target temperature by about 1 to 2 degrees to allow the user to warm up or to sleep .

In addition, the controller 160 may lower the target temperature value when the user sensed by the sleep sensor 1521 is in the non-REM surface level state 1 or in the non-REM surface state 2 state. The control unit 160 may maintain the target temperature value when the user sensed by the surface sensor 1521 is in the non-REM surface state 3, the non-REM surface state 4, or the REM surface state.

In addition, when the current time reaches a predetermined time (for example, two hours before the rising time) based on the rising time of the user analyzed by the analyzing unit 1522, the control unit 160 sets the target temperature value 1 < / RTI > to 2 degrees. Here, the temperature and time may vary depending on the season and the user's selection. That is, the target temperature value can be corrected in consideration of the temperature sensed by the temperature sensor 1511 and / or the state of the user sensed by the surface sensor 1521.

For example, immediately before the user enters the water surface during the winter, the first ambient temperature is sensed through the sensor unit 150 to automatically set the target temperature. In the first and second stages of the non-REM water level, So that it is possible to provide a pleasant environment required for sleeping.

Then, by maintaining the temperature at the non-REM level 3, 4 and REM level, the user can keep the sleeping at the optimum temperature required for the sleeping without having to reset the temperature.

It is also possible to set the average time of the off time from the time the user drives the mat device 100 to the wake up time or to set the average of the user as a timer is provided in the control unit 160, By automatically setting the rising time and raising the temperature in the range of 1 degree to 2 degrees before 1 to 2 hours of the rising time, it is possible to induce the user who senses the increased temperature to break the sleep

Thus, the user can be automatically adjusted to a suitable temperature according to the sleeping phase without having to wake up during sleep, thereby providing an environment for sleeping and weathering.

Thus, in the present embodiment, the body temperature, the ambient temperature, the pulse rate, and the temperature of the sleeping user can be detected through the sensor unit 150 that can detect vibration, sound, pressure, It is possible to analyze the present sleep state and pattern such as the number of breaths and to provide a comfortable sleeping environment by automatically controlling warmth and cold feeling according to each sleep state and pattern.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification and the modification are possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
