FIG. 5 is a diagram showing a longitudinal cross-section of a wearable air conditioning device 9 according to an exemplary embodiment. FIG. 6 is a cross-sectional view of a wearable air conditioning device 9 according to an exemplary embodiment.

Referring to Figures 5 and 6, a thermoelectric element 30, a front heat dissipation member 6, and a rear heat dissipation member 7 may be disposed on the upper part of the blowing fan 83. There may be a front heat dissipation member 6 and a rear heat dissipation member 7 in the radial direction of the blowing fan 83.

The blowing module 80 discharges the air inside the housing 1 toward the front heat radiating member 6 and the rear heat radiating member 7 so that the air moves along the first channel 60 and the second channel 70. You can.

Air discharged toward the front heat dissipation member 6 and the rear heat dissipation member 7 may move through the first channel 60 and the second channel 70. For example, the first airflow F1 passing through the first channel 60 may flow through the first channel 60 . The second airflow (F2) may flow through the second channel (70).

In the process of passing through the first channel 60, the first airflow F1 exchanges heat with the front heat dissipation member 6, and its temperature becomes lower than the surrounding temperature. For example, the temperature of the first airflow F1 passing through the first channel 60 may be 3°C or more lower than the ambient temperature. For example, the temperature of the first airflow F1 passing through the first channel 60 may be 5°C or more lower than the ambient temperature. For example, when the ambient temperature is 40°C, the temperature of the first airflow F1 may be 35°C or lower. The temperature of the first airflow (F1) that has completed heat exchange with the front heat dissipation member (6) may be lower than body temperature. However, the temperature of the first air flow (F1) is not limited to the above. The temperature of the first airflow F1 may vary depending on the amount of heat conducted to the contact surface 61 of the front heat dissipation member 6, the voltage of the battery 87, changes in ambient temperature, and the air volume of the blowing fan 83. In the process of passing through the second channel 70, the second airflow F2 exchanges heat with the rear heat dissipation member 7, and its temperature may become higher than the surrounding temperature. The temperature of the second airflow (F2) that has completed heat exchange with the rear heat dissipation member (7) may be 40°C or higher.

The first airflow (F1) that has completed heat exchange with the front heat dissipation member (6) may be discharged through the first outlet (40). The temperature of the discharged first air stream (F1) may be lower than the outside air. For example, the temperature of the discharged first air stream F1 may be 3°C or more lower than the outside air. For example, the temperature of the discharged first air stream F1 may be 5°C or more lower than the outside air. The discharged first airflow (F1) can transfer heat to the user in a convection manner. For example, by evaporating the user's sweat using the first airflow F1, a cooling sensation can be provided to the user. The user can obtain a cooling sensation from one surface 61 of the front heat dissipation member 6 and at the same time, a cooling sensation due to the first airflow F1 discharged from the first outlet 40. The user can transfer heat to the wearable air conditioning device (9) in two ways: conduction and convection.

The second airflow (F2) whose temperature has risen may be discharged through the second outlet (22). The temperature of the discharged second air stream (F2) may be higher than the outside air. The second outlet 22 may be disposed toward the rear. Through the second airflow F2, the heat dissipation efficiency of the rear heat dissipation member 7 can be increased. Thus, the rear 32 of the thermoelectric element 30 is prevented from overheating, and this prevents the temperature of the front 31 from increasing due to the temperature of the overheated rear 32.

The first partition 25 may block mixing of the first airflow F1 and the second airflow F2. When the first air stream (F1) and the second air stream (F2) do not mix, the temperature difference between the first air stream (F1) and the second air stream (F2) can be maintained. The first airflow (F1) and the second airflow (F2) may be discharged from the housing (1) in opposite directions. When the first airflow (F1) and the second airflow (F2) are discharged in opposite directions, only the intended type of airflow, for example, the first airflow (F1), can be delivered to the target, for example, the user.

Referring again to FIG. 2, the first outlet 40 may include a plurality of micro holes 43. The diameter of the microhole 43 may be 1 mm or less. The microhole 43 may be a hole through which numerous micrometer-sized holes emit a fine airflow. These fine holes 43 can be defined as windless holes. The wind speed of the airflow coming out of the microhole 43 may be 0.15 m/s or less. The first airflow (F1) discharged through the microhole 43 can prevent the skin from drying out or the hair from being blown away by the wind.

The surface level of the first outlet 40 may be located rearward than the surface level of the front housing 10. The front housing 10 surrounds the edge of the first outlet 40 and may include an edge area 13 that protrudes forward compared to the first outlet 40. The user may not directly contact the first outlet 40.

When the edge of the first outlet 40 is surrounded by the housing 1, the first airflow F1 may not flow smoothly. An air flow blocking prevention groove 130 through which the first air flow F1 passing through the first outlet 40 can move may be provided in the border area 13. The first airflow (F1) may be discharged to the outside through the airflow blocking prevention groove 130. The air flow blocking prevention groove 130 can facilitate the discharge of the first air flow (F1) to the outside. When the discharge of the first air stream (F1) to the outside becomes smooth, the flow of the first air stream (F1) may be smooth. A plurality of air flow prevention grooves 130 may be formed.

In the wearable air conditioner according to the above-described embodiment, the description focuses on the structure in which the first outlet 40 and the airflow blocking prevention groove 130 are provided in the housing 1. However, this is an exemplary structure and can be modified in various ways. You can.

The channel area 600 may protrude forward from the discharge area 610. The front housing 10a may protrude forward from the discharge area 610. The user may not directly contact the discharge area 610. Although not shown, the front housing 10a may include an airflow blocking prevention groove 130.

The air volume control unit 85 controls the air discharged from the blower fan 83 into a first airflow F1 discharged in a direction toward the front heat radiation member 6 and a second airflow F1 discharged in a direction toward the rear heat radiation member 7. It can be divided into airflow (F2). The wind volume control unit 85 can control the wind volume directed toward the front heat dissipation member (6). The air volume control unit 85 can adjust the air volume of the first airflow F1 discharged from the first outlet 40. For example, the air volume control unit 85 may rotate based on the axis A. Depending on the rotation angle of the air volume control unit 85, the air volume discharged from the first outlet 40 may vary.

The air volume control unit 85 may be connected to the air volume control unit 86. The air volume control unit 86 may be disposed in the rear housing 20. The user can move the air volume control unit 85 by manipulating the air volume control unit 86. The air volume control unit 86 may be in the form of a dial. However, the shape of the air volume control unit 86 is not limited to this and may vary. For example, although not shown, the air volume control unit 86 may be in the form of a lever. The air volume control unit 86 can be moved fully automatically through control of the control unit 88.

Referring to FIG. 9B, the air volume control unit 85 may guide the air discharged from the blower fan 83 toward the rear heat dissipation member 7. In this case, all of the air discharged from the blowing fan 83 becomes the second airflow F2 and moves toward the rear heat dissipation member 7, and the first airflow F1 may not be formed.
