WO 2008/117938 PCT/IKR2008/001037 Description A SLEEPING DEVICE WITH A HEATING OR COOLING APPARATUS Technical Field [1] The present invention relates to a sleeping device for cooling and heating, and more specifically, to a movable sleeping device for cooling and heating which may save cooling and heating costs by locally cooling and heating a room. [2] Background Art [3] Physical fatigue may be relieved during sleep and quality of sleep may be dependent on sleeping environments and conditions. A comfortable sleeping environment helps people to recover from fatigue. Especially temperature and moisture considerably affect the degree of fatigue recovery during sleep. Conventionally, auxiliary cooling and heating units have been used to adjust the temperature of room during sleep, such as cool air blowers, cooling fans, electric blankets, electric heaters, humidifiers, besides coolers and heaters operating in the room to provide a benign environment. And, a bed has been known, where warm air is drawn to the inside of the bed to allow for a local temperature adjustment and temperature may be differently adjusted with respect to each part of a human body. However, such a bed has a complicated con figuration and radiates harmful electromagnetic wave, and therefore, deteriorates the quality of sleep. [4] In addition, cooling or heating units employing a way to circulate cold water or heated water for cooling or heating continue to circulate water along pipes installed in the mattress or inside the bed, and therefore, wastes may be accumulated in the pipes, which may cause malodor. [5] A Korean Utility Model Registration No. 20-32206 discloses a heat-retaining bed which includes a heat-retaining bed comprising a heat-retaining cover having an air discharging hole and a central curtain 17, a receiving space for the heat-retaining cover between a body 2 and an inner body 3 that are arranged near one end of the heat retaining bed, a guiding member arranged in an inner wall of a groove, a roller located at an end of a supporting member of the heat-retaining cover, a rotational supporting member located at one end of a left supporting member, and an extendable member located at each supporting member and shaped as the letter "X". However, the heat retaining bed has a disadvantage in that the body is integrally formed with the bed, so that the body alone may not be separated from the bed, and the bed occupies broad space, and this may be out of harmony with the room.
WO 2008/117938 PCT/KR2008/001037 [6] Disclosure of Invention Technical Problem [7] The present invention has been designed to overcome the above problems, and an object of the present invention is to provide a sleeping device which may save costs for cooling and heating by locally cooling and heating a room. [8] The sleeping device may be also used even when a user sleeps on the floor as well as on the bed thanks to easy adjustment in height and convenient movement. [9] The sleeping device may be put aside in other places, with the heat-retaining cover folded, when not used. [10] Technical Solution [11] To achieve the above objects, the present invention provides a sleeping device for cooling and heating including: a body having a first compartment and a second compartment separated from the first compartment by a central partition, the body being opened at its front surface and its rear surface; a cooling unit mounted in the first compartment of the body; a heating unit mounted in the second compartment of the body; a leg supporting the body; a heat-retaining cover attached to an edge of a front surface of the body to reduce inflow and outflow of air; a supporter attached to the heat-retaining cover to support the heat-retaining cover; and a wheel attached to a lower end of the supporter and the leg to help the sleeping device to move.

[28] The body 100 includes a first compartment 120 and a second compartment 130 separated from each other by a central partition 110. A cooling unit 121 is mounted in the first compartment and a heating unit 131 is mounted in the second compartment. A heat-retaining cover 160 covers the front surface of the body 100 to reduce inflow and outflow of air. [29] A plurality of supporters 180 are attached to the heat-retaining cover 160 to maintain the shape of the heat-retaining cover. The supporter 180 is shaped as the letter n . The supporter 180 includes a hollow supporting part 181 and a supporter height adjusting part 182. The supporter height adjusting part 182 has plural pores for height adjustment WO 2008/117938 PCT/KR2008/001037 near a lower end thereof. The supporting part 181 has plural pores for height adjustment near an upper end thereof. The supporter height adjusting part 182 is inserted into the hollow supporting part 181. The supporter 180 may further include a supporter fixation member 183 that is inserted into a hole of the supporter supporting part 181 and a hole of the supporter height adjusting part 182 overlapping each other to fix the supporter supporting part 181 and the supporter height adjusting part 182. In addition, the supporter wheel 192 is attached to an end of the supporter supporting part 181, which enables the heat-retaining cover 160 to be folded and unfolded as shown in FIG. 1. FIG. 2 depicts an exemplary embodiment of the present invention, where the heat-retaining cover 160 has been unfolded for sleep. Referring to FIG. 2, the heat retaining cover 160 is attached to an edge of the front surface of the body 100, which enables cold air or warm air generated by the cooling unit or heating unit to stay in the heat-retaining cover 160 for a long time, so that an optimum temperature for sleep may be maintained with reduced power consumption. In addition, the heat-retaining cover 160, located opposite to the body 100, may have an open portion as shown in FIG. 2, through which a user may put his head outside the heat-retaining cover 160 during sleep. Air circulation occurring in the heat-retaining cover 160 may prevent a sudden difference in temperature between the room and the inside of the heat-retaining cover 160, and this may provide a better sleeping environment. [30] The body 100 further includes a leg 170 for supporting the body 100. The leg 170 is composed of a hollow leg supporting part 171, a hollow leg height adjusting part 172, and a leg fixation member 173 similarly to the supporter 180 shown in FIG. 5. The hollow leg supporting part 171 have an upper part and a lower part. The upper part has several pores. A wheel body 191 is attached to the lower part. The hollow leg height adjusting part 172 has several pores at its lower part. The leg fixation member 173 is inserted into a pore of the leg supporter 171 and a pore of the leg height adjusting part 172 overlapping each other to fix the leg supporter 171 and the leg height adjusting part 172. By doing so, the height of the leg 170 may be adjusted. The wheel 190 attached to the supporter 180 and the leg 170 permits the body 100 to be moved. Therefore, the sleeping device may be put aside in other places when not used. Furthermore, since the height of the leg 170 and the supporter 180 may be adjusted, the sleeping device may be used even when the user sleeps not on the bed but on the floor. [31] Referring to FIG. 3, the body 100 may further include filters 140 at its front and rear surfaces to purify air. The filter 140 includes a front filter 141 and a rear filter 142. The front filter 141 is located at the front surface of the body 100 to purify cooled or heated air flowing in the heat-retaining cover 160. The rear filter 142 is located at the rear surface of the body 100 to purify air flowing in the cooling unit 121 and the heating unit 131. Therefore, the rear filter 142 may enhance the durability of the cooling unit WO 2008/117938 PCT/KR2008/001037 121 and the heating unit 131 as well as purify air in the room. [32] An air adjustment plate 150 is placed before the front surface of the body 100. The air adjustment plate 150 has several pores 151 as shown in FIG. 4. The air coming out of the cooling unit 121 and the heating unit 131 circulates while passing through the pores 151, and therefore, there occurs a constant time interval between a point of time when the air comes out of the cooling unit 121 and the heating unit 131 and a point of time when the air reaches a user's skin. This plays a role in preventing the user's skin from being easily dried, and maintaining the temperature in the heat-retaining cover 160 constant. [33] The air adjusting plate 150 may further include an auxiliary plate 152 that adjusts the size of the pore 151. If it is desired to swiftly adjust the temperature in the heat retaining cover 160, the auxiliary plate 152 may be kept open to increase the amount of flowing air. [34] The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. The description of the foregoing embodiments is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art. [35] [36] Sequence Listing [37] sleeping device, body, cooling unit, heating unit
