Additionally, the contact layer 20 may be provided with a thin thickness to effectively apply the cold heat of the thermoelectric module 30 to the user's skin. For example, the contact layer 20 may be provided with a thickness of less than 1 cm.

Additionally, the contact layer 20 may be provided in a shape that corresponds to the user's face. Since the user's eye area and mouth area are vulnerable to low temperatures, the contact layer 20 may be provided in a form with holes around the eyes and mouth. The contact layer 20 may be provided in the form of a hole in the nose area for convenience, such as improving adhesion.

Additionally, the contact layer 20 may be provided with a viscous liquid to improve adhesion to the skin. For example, the contact layer 20 may be provided wet with a viscous emulsion.

Additionally, the contact layer 20 may contain various functional materials 21 to obtain additional skin improvement effects. For example, the contact layer 20 may be coated with a coating liquid containing the functional material 21 .

Additionally, the contact layer 20 may be provided in various forms. The contact layer 20 may be provided to be fixedly disposed on the skin whitening mask 10, but may also be provided to be temporarily disposed between the thermoelectric module 30 and the user's skin when the skin whitening mask 10 is worn. That is, the contact layer 20 is independently constructed in a structure that is attachable and detachable from the mask 10, and may be separable from the mask 10.

For example, the contact layer 20 may be provided as an independent sheet disposed between the thermoelectric module 30 and the user's skin when the skin whitening mask 10 is worn. For another example, the contact layer 20 may be provided in the form of an independent gel that is applied and placed between the thermoelectric module 30 and the user's skin when the skin whitening mask 10 is worn.

When the contact layer 20 of the mask 10 is arbitrarily replaced by the user and replaced with a contact layer 20 containing the functional material 21 that exhibits side effects at low temperatures, the user's skin is cooled by the mask 10. As a result, rashes and skin damage may occur on the user's skin.

Therefore, according to an embodiment of the present specification, an identification tag 22 may be placed on the contact layer 20 as a means for identification of the contact layer 20.

Figure 3 is a diagram showing a contact layer where an identification tag is placed according to an embodiment of the present specification.

Referring to FIG. 3, an identification tag 22 may be placed on the contact layer 20 as a means for identification of the contact layer 20.

The identification tag 22 may be placed at any position on the contact layer 20, and may be placed at a position corresponding to where the tag recognition module 74 that recognizes the identification tag 22 is installed.

The identification tag 22 may be provided as, for example, an EEPROM or RFID tag.

The identification tag 22 may have data regarding the contact layer 20 on which the identification tag 22 is placed.

The identification tag 22 may have identification data regarding the contact layer 20 on which the identification tag 22 is placed. For example, the controller 50 controls the thermoelectric module 30 so that power is applied to the thermoelectric module 30 only when the identification tag 22 is recognized by the tag recognition module 74 and the contact layer 20 can be identified. ) can be controlled. That is, the controller 50 may not apply power to the thermoelectric module 30 if the identification tag 22 is not recognized by the tag recognition module 74.

The identification tag 22 may have identification data of the functional material 21 accommodated in the contact layer 20 where the identification tag 22 is disposed. For example, when the identification tag 22 is recognized by the tag recognition module 74, the controller 50 recognizes the functional material 21 accommodated in the contact layer 20 through the identification data of the identification tag 22. can be identified.

The identification tag 22 is set to the cooling condition of the thermoelectric module 30 (cooling condition of the first main surface 31) corresponding to the identification data of the functional material 21 accommodated in the contact layer 20 where the identification tag 22 is disposed. ) can have data about. For example, when the identification tag 22 is recognized by the tag recognition module 74, the controller 50 sets the cooling conditions (first main surface) of the thermoelectric module 30 corresponding to the identification data of the identification tag 22. Data regarding the cooling conditions (31) can be obtained, and the thermoelectric module 30 can be controlled according to the obtained cooling conditions.

At least one thermoelectric module 30 may be configured to generate heat or absorb heat as power is applied. For example, as power is applied, at least one thermoelectric module 30 may apply cold heat to the user's skin through the contact layer 20.

A thermoelectric module uses thermoelectric effects such as the Seeback effect or Peltier effect to perform thermoelectric operations such as power generation using temperature differences or heating/cooling using electrical energy. It may refer to a module that performs execution. In general, thermoelectric modules are provided in the form of a thermoelectric element composed of an N-P semiconductor electrically connected to a flat substrate made of mostly ceramic materials, but the thermoelectric module 30 in this specification may include a flexible thermoelectric module. You can. The thermoelectric element may be a device that induces a thermoelectric effect such as the Seebeck effect or Peltier effect. Basically, thermoelectric elements may include heterogeneous materials that form a thermoelectric couple that induces a thermoelectric effect. A thermocouple can generate a temperature difference when electrical energy is applied, and conversely, it can produce electrical energy when a temperature difference is applied. An example of a thermoelectric element is a pair of bismuth and antimony. Also, mainly a pair of N-type semiconductor and P-type semiconductor can be used as a thermoelectric element.

At least one thermoelectric module 30 has two main surfaces including a first main surface 31 disposed in contact with the upper part of the contact layer 20 and a second main surface 32 located on the opposite side of the first main surface 31. You can have For example, at least one thermoelectric module 30 includes a first main surface 31 disposed in contact with the upper part of the contact layer 20 and a second main surface 32 located on the opposite side of the first main surface 31. It has two main surfaces 31 and 32, and as power is applied, the first main surface 31 is cooled and cold heat can be applied to the user's skin through the contact layer 20.

A pair of main surfaces 31 and 32 may include a first main surface 31 and a second main surface 32 that are spaced apart from each other to face each other. The first main surface 31 and the second main surface 32 can support thermoelectric elements or electrodes disposed between them. In addition, the first and second main surfaces 31 and 32 may perform the function of protecting the thermoelectric element or electrode therein from the outside.

Additionally, the pair of main surfaces 31 and 32 may be made of a material that facilitates heat conduction. For example, a pair of main surfaces 31 and 32 may be a substrate made of copper.

Additionally, at least one thermoelectric module 30 according to an embodiment of the present specification may be provided as a flexible thermoelectric module 30 having flexibility. The mask 10 can be manufactured in a complex shape (e.g., a shape corresponding to the face), such as curved, in order to adhere well to the user's face. If the flexible thermoelectric module 30 is used, manufacturing difficulties can be reduced. It is possible to provide a mask 10 in a shape that fits more closely to the face.

To this end, the pair of main surfaces 31 and 32 of the thermoelectric module 30 and their interior may be made of a flexible material. For example, a pair of main surfaces 31 and 32 may be a thin polyimide (PI: polyimide) film. Polyimide film not only has excellent flexibility, but although it does not have high thermal conductivity, it can be manufactured in a thin thickness, so it can be advantageous for heat conduction.

Since the skin characteristics of the multiple areas that make up a person's body part are different, cooling needs to be done differently for each area of the body part. For example, conditions in which skin damage or pigmentation is suppressed may be different for each of the plurality of areas forming the facial area. Therefore, according to an embodiment of the present specification, the plurality of thermoelectric modules 30 can be classified into a plurality of thermoelectric module groups 33, and the plurality of thermoelectric module groups 33 are independent from other thermoelectric module groups 33. It can be controlled by the controller 50. The thermoelectric module group 33 may be comprised of at least one thermoelectric module 30. Here, each of the plurality of thermoelectric module groups 33 may be divided by region of the user's face.

FIG. 4 is a diagram illustrating thermoelectric modules disposed inside a mask according to an embodiment of the present specification.

Referring to FIG. 4, the plurality of thermoelectric modules 30 may be classified into a plurality of thermoelectric module groups 33a, 33b, 33c, and 33d for each region of the user's face.

Each thermoelectric module group (33a, 33b, 33c, 33d) can be divided according to the area of the user's face where it is placed. For example, each thermoelectric module group 33a, 33b, 33c, and 33d may be divided into areas with similar temperatures among areas forming the user's face.

Unlike the internal temperature of a person, the temperature of human skin is distributed at about 32-34°C rather than 36-37°C, and the temperature distribution of each area that makes up the human face varies from person to person, but in general, the temperature distribution of the facial area is The temperature distribution is symmetrical in the shape of blood vessels, and can be divided into several areas with similar temperatures depending on the temperature. The forehead area has a lot of blood vessels and the hair prevents heat from escaping, so the temperature is high, while the chin area has a high temperature because there are many blood vessels distributed around it. The area on both sides of the nose also has relatively many blood vessels, so the temperature is high, while the area on both cheeks does not have many blood vessels, so the temperature is relatively low. The temperature of the nose area is lower than that of other areas of the face due to breathing outside air. That is, in general, the skin temperature of a person's face is measured to be high in the following order: forehead area, chin area, area on both sides of the nose, both cheeks, and nose area. Depending on the temperature, the forehead area, chin area, area on both sides of the nose, It can be divided into both cheek areas and nose area.

Therefore, according to an embodiment of the present specification, the plurality of thermoelectric modules 30 include a first thermoelectric module group 33a disposed in the forehead region and chin region, and a second thermoelectric module group 33b disposed in regions on both sides of the nose. It can be divided into a third thermoelectric module group 33c disposed in the cheek area and a fourth thermoelectric module group 33d disposed in the nose area.

A plurality of thermoelectric module groups (33a, 33b, 33c, 33d) can be controlled by the controller 50 independently from other thermoelectric module groups (33a, 33b, 33c, 33d). For example, the controller 50 independently controls on/off, cooling time, cooling temperature, operation mode, etc. of a plurality of thermoelectric modules 30 for each thermoelectric module group 33a, 33b, 33c, and 33d. can do.

The plurality of thermoelectric module groups 33a, 33b, 33c, and 33d may be cooled to a lower temperature as the thermoelectric module group 33 is disposed in a region where the temperature of the facial area is high. That is, the controller 50 includes a plurality of thermoelectric module groups 33a, 33b, 33c, and 33d so that the first main surface 31 is cooled to a lower temperature as the thermoelectric module group 33 is disposed in an area where the temperature of the facial area is higher. can be controlled.

For example, the first thermoelectric module group 33a disposed in the forehead and chin areas where the temperature is high may have its first main surface 31 cooled to -15°C, and the first thermoelectric module group 33a disposed in the nose area where the temperature is low can be cooled to -15°C. The first main surface 31 of the 4 thermoelectric module group 33d can be cooled to 0°C.

In addition, the cooling time for the plurality of thermoelectric module groups 33a, 33b, 33c, and 33d may be longer as the thermoelectric module group 33 is disposed in an area where the temperature of the facial area is high. That is, the controller 50 configures a plurality of thermoelectric module groups 33a, 33b, 33c, and 33d so that the first main surface 31 is cooled for a longer time as the thermoelectric module group 33 is disposed in an area where the temperature of the facial area is higher. You can control it.

For example, the first thermoelectric module group 33a disposed in the forehead and chin areas where the temperature is high may be cooled so that the cooling duration is 120 seconds, and the fourth thermoelectric module group disposed in the nose area where the temperature is low. (33d) can be cooled so that the cooling duration is 60 seconds.

However, the thermoelectric module group 33 described above is not limited to this, and the thermoelectric module group 33 may be more or less thermoelectric module groups 33 than the plurality of thermoelectric module groups 33 described above, and each thermoelectric module Group 33 is not limited to the above description.

Additionally, according to an embodiment of the present specification, when at least one thermoelectric module 30 is disposed inside the mask 10, the separation distance may be adjusted.

Figure 5 shows how cold heat from a mask according to an embodiment of the present specification is transmitted to the skin.

The cold heat of the first main surface 31 of the thermoelectric module 30 is applied to the user's skin through the contact layer 20. When cold heat applied to the skin is transmitted through the skin, it is transmitted in a spherical shape within the skin.

Referring to FIG. 5, it can be seen that a cold heat transfer hemisphere is formed on the skin centered on the thermoelectric module 30. That is, the temperature of the skin at the point where the thermoelectric module 30 is placed is different from the temperature of the skin at the point where the thermoelectric module 30 is not placed.

When a plurality of thermoelectric modules (30-1, 30-2, 30-3) are disposed on the mask 10, if the separation distance between each thermoelectric module (30-1, 30-2, 30-3) is too long, each thermoelectric module Cold heat may not be properly transmitted to a portion of the modules (30-1, 30-2, and 30-3) and partial whitening may occur, resulting in uneven skin tone. In order to prevent partial whitening, when a plurality of thermoelectric modules (30-1, 30-2, 30-3) are arranged, the separation distance between each thermoelectric module (30-1, 30-2, 30-3) can be adjusted. You can.

The plurality of thermoelectric modules (30-1, 30-2, 30-3) have a separation distance that allows cold heat to be applied to the midpoint between each thermoelectric module (30-1, 30-2, 30-3) when cooling. It can be placed as . For example, the plurality of thermoelectric modules (30-1, 30-2, 30-3) have a separation distance in the range of 1 mm to 50 mm between each thermoelectric module (30-1, 30-2, 30-3). can be placed.

When cooling, the plurality of thermoelectric modules (30-1, 30-2, 30-3) measure the skin temperature at the midpoint between each thermoelectric module (30-1, 30-2, 30-3) and the thermoelectric module (30-1). , 30-2, 30-3) may be arranged based on the skin temperature at the placed point.

When the plurality of thermoelectric modules (30-1, 30-2, 30-3) are cooled, the difference between the skin temperature at the midpoint between each thermoelectric module (30) and the skin temperature at the point where the thermoelectric module (30) is placed is measured. They can be placed at a separation distance that ensures that the temperature is below a set temperature. For example, the first thermoelectric module (30-1) measures the skin temperature at the midpoint of the second thermoelectric module (30-2) and the temperature at any one of the points where each thermoelectric module (30-1, 30-2) is placed. They can be placed at a separation distance that ensures that the difference in skin temperature is less than 10°C.

As is well known, when heat is absorbed on one side of a thermoelectric element, heat is generated on the other side, and vice versa. For example, when heat absorption occurs on the first main surface 31 of the thermoelectric module 30 to cool the user's skin, heat is generated on the second main surface 32 of the thermoelectric module 30. ) If the heat generated on the side is not properly dissipated, not only the amount of power applied to the mask 10 increases, but also the cooling efficiency at the first main surface 31 may be reduced. Accordingly, the mask 10 may include a heat dissipation layer 40 to receive and dissipate heat generated when the first main surface 31 is cooled.

The heat dissipation layer 40 is disposed on the upper part of the thermoelectric module 30 so as to contact the second main surface 32 of the thermoelectric module 30, and absorbs the heat generated when the first main surface 31 is cooled through the second main surface 32. Heat can be transferred and dissipated. For example, the heat dissipation layer 40 may be made of a material with high specific heat or thermal conductivity, or may be installed with a fluid circulator or fan that exchanges heat through a circulating fluid, or may be constructed or installed by combining various heat dissipation means. .

In addition, the heat dissipation layer 40 may be provided in a protruding shape with a concave-convex structure in which the surfaces in contact with the outside of the heat dissipation layer 40 are alternately protruded and indented to increase the area in contact with the outside to improve heat dissipation.

Additionally, the heat dissipation layer 40 may be independently configured and formed into a structure that can be replaced or detached.

Generally, the temperature difference between the heat absorbing surface and the heating surface of the thermoelectric module has the characteristic of being saturated between approximately 30°C and 55°C as power is applied. That is, when power is continuously applied to the thermoelectric module, the temperature difference between the heat-absorbing surface and the heating surface of the thermoelectric module is maintained between approximately 30°C and 55°C. Therefore, if the temperature of the heating surface of the thermoelectric module becomes too high, the temperature of the heat absorbing surface of the thermoelectric module also increases, and a problem may occur in which the mask 10 cannot cool the user's skin to the targeted cooling temperature. The mask 10 has a first main surface 31 and a second main surface ( 32) may include a heat dissipation layer 40 that maintains the temperature difference between the temperature below a preset temperature (for example, 30°C to 55°C).

Therefore, according to an embodiment of the present specification, the heat dissipation layer 40 is disposed on the upper part of the thermoelectric module 30 so as to contact the second main surface 32 of the thermoelectric module 30, and the temperature of the first main surface 31 and In order to maintain the temperature difference of the second main surface 32 below the preset temperature, the heat generated during cooling of the first main surface 31 is transmitted and absorbed through the second main surface 32 and the latent heat at the melting point is absorbed. It can be provided as a phase change material heat dissipation layer 40a including a phase change material (PCM) that maintains the temperature of the second main surface 32 constant.

Phase change materials are materials that have large latent heat and can store and release a large amount of energy when changing phase. It is a substance that accumulates or releases heat through the process of changing from one state to another, such as from a solid to a liquid state, or from a liquid to a solid state. When the external temperature falls below the melting point of the phase change material, the phase change material changes phase. As it changes, it releases a large amount of latent heat, and when the external temperature rises above the inherent melting point of the phase change material, the phase changes and a large amount of latent heat is absorbed. Therefore, because phase change materials absorb or release a lot of heat as the state of the material changes, they can maintain the temperature corresponding to the melting point constant for a longer period of time than other materials. Using this phase change material, the phase change material heat dissipation layer 40a maintains the temperature of the second main surface 32 at a constant temperature to reduce the difference between the temperature of the first main surface 31 and the second main surface 32. It can be maintained below a preset temperature. Here, the preset temperature may be selected as an appropriate value in the range of 30°C to 55°C.

The phase change material heat dissipation layer 40a may include a phase change material having a melting point within a specific range in order to maintain the difference between the temperature of the first main surface 31 and the second main surface 32 below a preset temperature. You can. For example, the phase change material heat dissipation layer 40a may include a phase change material having a melting point of -15°C to 40°C, such as C ₁₂ H ₂₆ , C ₁₆ H ₃₄ , and C ₂₀ H ₄₂ . .

In addition, the phase change material heat dissipation layer 40a has a phase change of mass determined based on the input power of the thermoelectric module 30, usage time, heat absorption of the first main surface 31, and latent heat at the melting point of the phase change material. May contain substances.

For example, the mass (G) of the phase change material included in the phase change material heat dissipation layer 40a may be determined by Equation 1 below.

-Here, Q _C is the heat absorption of the first main surface 31, P is the input power of the thermoelectric module 30, t is the usage time of the thermoelectric module 30, and ΔH is the latent heat at the melting point of the phase change material. -

The heat absorption amount Q _C of the first main surface 31 may be defined as the amount of heat absorbed per hour by the first main surface 31 of the thermoelectric module 30.

For example, the heat absorption Qc of the first main surface 31 is 3000 J/Sec, the input power P of the thermoelectric module 30 is 2.3 W, the usage time t of the thermoelectric module 30 is 40 seconds, and the melting point of the phase change material When the latent heat ΔH in is 230 J/g, the mass (G) of the phase change material included in the phase change material heat dissipation layer 40a of the mask 10 is G = (3000 + 2.3) according to Equation 1 described above. ) × 40 / 230 = 522.14 g.

It should be noted that the method of determining the mass of the phase change material included in the phase change material heat dissipation device 40a is not limited to the above-described method and can be performed in various ways.

Additionally, the phase change material heat dissipation layer 40a may be independently configured and formed into a structure that can be replaced or detached. For example, the phase change material heat dissipation layer 40a may be configured in a block shape and may be connected to or separated from the mask 10.

In addition, the phase change material heat dissipation layer 40a is disposed on the top of at least one thermoelectric module 30 and is placed in a housing (not shown) provided to position the phase change material heat dissipation layer 40a. ) may be arranged to enable detachment or replacement. Through this, the phase change material heat dissipation layer 40a may be separated from the mask 10, cooled separately, and then reinstalled on the mask 10.

The heat transfer member 41 is made of a material with high thermal conductivity and, for example, may be made of a metal material such as aluminum or copper.

Additionally, the heat transfer member 41 may be provided in various forms. For example, the heat transfer member 41 may be provided in the form of a bead (41a), a rod shape (41b) penetrating the heat dissipation layer 40, or a coil shape (41c).

Figure 7 shows a cross-sectional view of a mask including a metal heat dissipation layer according to an embodiment of the present specification.

Referring to FIG. 7, in order to improve the heat dissipation ability of the heat dissipation layer 40, the metal heat dissipation layer 40b is phased so that one side is in contact with the thermoelectric module 30 and the other side is in contact with the phase change material heat dissipation layer 40a. It may be disposed between the change material heat dissipation layer 40a and the thermoelectric module 30.

The metal heat dissipation layer 40b may be made of a metal material with high thermal conductivity. For example, the metal heat dissipation layer 40b may be made of a metal material such as aluminum or copper.

Additionally, the metal heat dissipation layer 40b may have a convex-convex structure on the surface in contact with the phase change material heat dissipation layer 40a. For example, the metal heat dissipation layer 40b is protruded in a concave-convex structure with alternating protrusions and indentations on the surface in contact with the phase change material heat dissipation layer 40a, and the protruding metal heat dissipation layer 40b has various shapes. can be provided.

The handle may be made of a material with low thermal conductivity to prevent the user from feeling discomfort due to heat when the outer cover 42 becomes hot due to heat generated from the second main surface 32. For example, the handle may be made of a material with low thermal conductivity, such as rubber. Additionally, the handle may be provided to be placed on another component of the mask 10, such as the heat dissipation layer 40, rather than on the outer cover 42.

Additionally, the vibration generating module 72 may output vibration to relieve the user's pain while the user's skin is cooled. For example, the vibration generation module 72 may output vibration (eg, vibration massage) while cold heat is applied to the user's skin through the thermoelectric module 30 and apply vibration to the user's skin.

The vibration generation module 72 determines that the stronger the intensity of cold heat applied to the user's skin through the thermoelectric module 30 (that is, the lower the cooling temperature of the first main surface 31 or the lower the cooling time of the first main surface 31). (the longer it is), the stronger vibration can be output.

Additionally, the vibration generation module 72 may output vibrations to provide notifications and vibrations to relieve the user's pain differently.

For example, the contact detection module 73 may be disposed on the contact layer 20.

The contact detection module 73 may generate a skin detection signal when it detects the user's skin. Alternatively, the contact detection module 73 may generate a non-detected skin signal when the user's skin is not detected.

The contact detection module 73 may be used as a means to determine when cooling of the first main surface 31 begins. For example, when the contact detection module 73 detects the user's skin, it generates a skin detection signal and sends the corresponding signal to the controller 50, and when the controller 50 receives the skin detection signal, the first main surface 31 ) can be controlled to start cooling of the thermoelectric module 30.

For example, the contact detection module 73 may be composed of at least one contact detection sensor that detects contact through electrical characteristics generated when the user touches the skin, or a heat detection sensor that detects a person's heat.

Additionally, the skin whitening mask 10 may further include a tag recognition module 74 that recognizes the identification tag 22.

The tag recognition module 74 may be placed in a place where the identification tag 22 can be recognized, such as the thermoelectric module 30, heat dissipation layer 40, external cover 42, and controller 50. For example, the tag recognition module 74 may be installed in the inner space of the mask 10 corresponding to where the identification tag 22 is located on the contact layer 20.

The tag recognition module 74 can recognize the identification tag 22. For example, the tag recognition module 74 may read data of the identification tag 22 placed on the contact layer 20 and identify the identification tag 22.

The tag recognition module 74 can read or write data of the identification tag 22 placed on the contact layer 20. For example, the tag recognition module 74 recognizes the identification tag 22 and reads the identification data contained in the identification tag 22, and the controller 50 recognizes the functional material contained in the contact layer 20 through the identification data. (21) can be identified. For another example, the tag recognition module 74 recognizes the identification tag 22 and determines the cooling conditions (cooling conditions of the first main surface 31) of the thermoelectric module 3 corresponding to the identification data of the identification tag 22. ), the controller 50 can control the thermoelectric module 30 according to the cooling condition data.

The tag recognition module 74 may be provided as, for example, an RFID reader, RFID reader writer, EEPROM, etc.

However, it is not limited to the above-described configuration, and the controller 50 may have more or less configurations than the above-mentioned configuration, and each configuration is not limited to the above-described description.

Below, a first embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described.

<First Example>

Figure 10 is a graph showing the temperature change over time on the first main surface of the thermoelectric module according to the first embodiment of the present specification.

If the user's skin is cooled too excessively, skin damage may occur due to skin freezing, and if the user's skin is cooled too weakly, pigmentation due to cooling of melanocytes may not be suppressed.

Therefore, the controller 50 according to an embodiment of the present specification operates the thermoelectric module 30 in a whitening mode in which the first main surface 31 is cooled under cooling conditions to suppress pigmentation by melanocytes and prevent skin damage. You can control it. Referring to FIG. 10, it can be seen that the thermoelectric module 30 is controlled by the controller 50 to perform a whitening mode in which the first main surface 31 is cooled to a cooling temperature of 5°C for 120 seconds.

Hereinafter, the time during which the first main surface 31 is cooled in the whitening mode is referred to as the whitening time, the temperature of the first main surface 31 while the whitening mode is performed is referred to as the whitening temperature, and the temperature of the first main surface 31 while the whitening mode is performed is the whitening temperature. The temperature range is referred to as the whitening temperature range.

The controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled within a specific temperature range in order to suppress pigmentation of the user's skin by melanocytes and prevent skin damage due to cooling. For example, the controller 50 sets the first main surface 31 within the -15°C to 15°C temperature range, which is the whitening temperature range, in order for the user's skin to reach a target temperature at which pigmentation by melanocytes is suppressed. The thermoelectric module 30 can be controlled to cool to a temperature lower than the target temperature. This means that if the temperature of the first main surface 31 is too low, skin damage may occur due to freezing of skin tissue, and if the temperature of the first main surface 31 is too high, the effect of suppressing pigmentation by melanocytes may be low. Because there is.

Here, the target temperature may be a temperature of 4°C to 27°C. Since the skin whitening effect due to skin cooling increases as the skin temperature is maintained lower, the target temperature may be a temperature of 27°C or lower for the skin whitening effect due to skin cooling to substantially occur. In addition, actual freezing of human skin tissue does not occur before the skin temperature reaches -4°C to -10°C, but when the skin temperature falls below 4°C, tissue damage occurs due to ischemia and thrombosis in small blood vessels. Because this can occur, the target temperature may be above 4°C to prevent skin damage due to cooling of the skin.

However, the cooling temperature of the first main surface 31 controlled by the controller 50 does not need to be limited to the above description, and the cooling temperature of the first main surface 31 is in the -30°C to 35°C temperature range. It may vary depending on the situation, such as whether it can be maintained at . Additionally, the target temperature does not need to be limited to the above-mentioned description, and the target temperature may vary depending on the situation, such as a temperature of -10°C to 35°C.

In addition, the controller 50 prevents skin damage due to cooling, and in order to suppress pigmentation by melanocytes, the whitening time, which is the time for which cooling of the first main surface 31 lasts, is set to the first time necessary to suppress pigmentation. The thermoelectric module 30 can be controlled to be maintained longer than the second time and shorter than the second time during which skin damage occurs. For example, the controller 50 suppresses pigmentation caused by melanocytes, but in order to prevent skin damage, the cooling time of the first main surface 31 is 5 seconds required to suppress pigmentation or damage to the skin occurs. The thermoelectric module 30 can be controlled to maintain the temperature within 300 seconds. For another example, the thermoelectric module 30 may be controlled so that the cooling time of the first main surface 31 is maintained between 5 seconds, which is necessary to suppress pigmentation, and 900 seconds, which is likely to cause microscopic damage to the skin.

Here, the first time may mean the minimum time required to suppress pigmentation due to cooling of melanocytes, and if the skin is cooled for a time shorter than the first time, sufficient cooling of the melanocytes is not achieved and pigmentation is suppressed. It can't be. For example, the first time may be at least 5 seconds for the skin whitening effect due to cooling of the skin to substantially occur. However, the first time may vary depending on the situation, such as at least 0.5 seconds in order to minimize the skin whitening effect due to cooling of the skin.

Additionally, the second time may mean the time when skin damage begins to occur due to cooling of the skin, and if the skin is cooled for a longer time than the second time, skin damage may occur. For example, the second time may be up to 300 seconds to prevent tissue damage due to local anemia and blood clots in small blood vessels caused by cooling the skin for a long period of time. However, the second time may vary depending on the situation, such as up to 900 seconds, which is the time when direct damage to the skin occurs as well as the possibility of microscopic damage to the skin by cooling the skin for a long period of time.

The cooling duration of the first main surface 31 controlled by the controller 50 need not be limited to the above-described description and may be determined in various ways.

Additionally, the controller 50 may control the thermoelectric module 30 so that the higher the temperature at which the first main surface 31 is cooled, the longer the cooling time for the first main surface 31 is. For example, the controller 50 controls the thermoelectric module 30 so that the cooling time for the first main surface 31 is longer when the temperature at which the first main surface 31 is cooled is 5°C than when the temperature at which the first main surface 31 is cooled is -15°C. ) can be controlled.

*In addition, the controller 50 according to an embodiment of the present specification may control the thermoelectric module 30 based on the skin temperature measured from the skin temperature sensor. To this end, the controller 50 may store the result of the input in the storage unit 54 in the form of a function or a look-up table and use it for calculation. For example, the storage unit 54 may store a current/voltage table regarding current and/or voltage for each skin temperature intensity. The controller 50 may determine the amount of current/voltage to be applied by referring to the current/voltage table based on the measured skin temperature.

The controller 50 uses a thermoelectric module to vary the cooling conditions of the first main surface 31 based on the skin temperature measured from the skin temperature sensor in order to prevent skin damage due to cooling and suppress pigmentation by melanocytes. 30) can be controlled.

The controller 50 may control the thermoelectric module 30 so that the temperature at which the first main surface 31 is cooled varies based on the skin temperature measured by the skin temperature sensor. For example, the controller 50 lowers the temperature at which the first main surface 31 is cooled when the measured skin temperature is higher than the target temperature, and cools the first main surface 31 when the measured skin temperature is lower than the target temperature. The thermoelectric module 30 can be controlled to increase the temperature. For another example, the controller 50 controls the thermoelectric module 30 to cool the first main surface 31 to a temperature where the measured skin temperature is maintained at the target temperature when the measured skin temperature reaches the target temperature. You can.

The controller 50 may control the thermoelectric module 30 so that the cooling time of the first main surface 31 varies based on the skin temperature measured from the skin temperature sensor. For example, when the measured skin temperature is higher than the target temperature, the controller 50 increases the cooling time for the first main surface 31, and when the measured skin temperature is lower than the target temperature, the controller 50 increases the cooling time for the first main surface 31. The thermoelectric module 30 can be controlled to reduce the time required.

Additionally, the controller 50 may control the thermoelectric module 30 so that the time for which the measured skin temperature is maintained at the target temperature is longer than the time required to suppress pigmentation and shorter than the time for skin damage to occur. For example, the controller 50 may control the thermoelectric module 30 so that the measured skin temperature maintains the target temperature (4°C to 27°C) for 4 to 120 seconds.

However, the first embodiment does not necessarily need to be implemented in the method described above, and may be implemented in various ways, such as being implemented in combination with other embodiments depending on the situation.

<Second Embodiment>

Below, a second embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described. Hereinafter, descriptions that overlap with the previous embodiment will be omitted. That is, technical ideas that can be used in the previous embodiment are not redundantly explained in the second embodiment.

Figure 11 is a graph showing the temperature change over time of the first main surface of the thermoelectric module according to the second embodiment of the present specification.

If the mask 10 cools the user's skin in only one whitening mode, it is difficult to achieve efficient skin whitening. This means that if the mask 10 cools the user's skin only in a whitening mode with a temperature that is too low, damage to the user's skin is likely to occur, and if the mask 10 cools the user's skin only in a whitening mode with a temperature that is too high, pigmentation by melanocytes is suppressed. This is because the effectiveness may decrease.

Specifically, first, the mask 10 cools the user's skin at a low first whitening temperature lower than the second whitening temperature, thereby rapidly lowering the user's skin temperature and increasing the skin whitening effect. However, here, if the mask 10 cools the user's skin to a low first whitening temperature for a long time, skin damage may occur due to the low temperature, so the first whitening time for maintaining the first whitening temperature may be kept relatively short. there is.

Next, the mask 10 cools the user's skin to a second whitening temperature that is higher than the first whitening temperature to reduce skin damage due to low temperature, but can increase the skin whitening effect by cooling the user's skin for a longer period of time. That is, the second whitening time during which the mask 10 maintains the second whitening mode may be longer than the first whitening time during which the mask 10 maintains the first whitening mode.

Therefore, the controller 50 according to an embodiment of the present specification may control the thermoelectric module 30 so that the first whitening mode and the second whitening mode under different cooling conditions are sequentially performed for efficient skin whitening. Referring to FIG. 11, the thermoelectric module 30 is controlled by the controller 50 to cool the first main surface 31 to a cooling temperature of T1 for t1, in which the first main surface 31 is higher than T1. It can be seen that the second whitening mode, which is cooled at the cooling temperature T2 for t2 longer than t1, is sequentially performed.

The controller 50 may control the thermoelectric module 30 so that the first whitening mode and the second whitening mode under different cooling conditions are sequentially performed for efficient skin whitening.

For example, first, the controller 50 sets the thermoelectric module 30 to perform a first whitening mode having a first whitening temperature lower than the second whitening temperature and a first whitening time shorter than the second whitening time. You can control it.

Next, the controller 50 may control the thermoelectric module 30 to perform a second whitening mode having a second whitening temperature higher than the first whitening temperature and a second whitening time longer than the first whitening time. there is.

In addition, the controller 50 can control the thermoelectric module 30 in a plurality of whitening modes rather than two whitening modes, and the thermoelectric module 30 in various combinations of whitening modes, such as each whitening mode being repeated sequentially. can be controlled.

However, the second embodiment does not necessarily need to be implemented in the method described above, and may be implemented in various ways, such as being implemented in combination with other embodiments depending on the situation.

<Third Embodiment>

Hereinafter, a third embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described. Hereinafter, descriptions that overlap with the previous embodiment will be omitted. That is, technical ideas that can be used in the previous embodiment are not redundantly explained in the third embodiment.

Figure 12 is a graph showing the temperature change over time of the first main surface of the thermoelectric module according to the third embodiment of the present specification.

In general, when the user's skin is cooled, in addition to the skin whitening effect, secondary effects such as skin swelling reduction effect and skin fat decomposition effect may occur on the user's skin. However, the optimal temperature at which the skin whitening effect occurs and the optimal temperature at which secondary effects such as skin swelling reduction effect and skin fat decomposition effect occur are slightly different.

Generally, the cooling temperature for the effects of swelling reduction and fat decomposition to occur is higher than the cooling temperature for the whitening effect to occur, and the cooling time for the puffiness reduction and fat decomposition effects to occur is the cooling time for the whitening effect to occur. longer than Here, if the user's skin is cooled with repeated increases and decreases in temperature, the fat decomposition effect may increase.

Therefore, the controller 50 according to an embodiment of the present specification can control the thermoelectric module 30 so that the first main surface 31 is cooled even under conditions in which other secondary effects occur. For example, the controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled to a condition where effects such as swelling reduction or fat decomposition occur.

Referring to FIG. 12, after the thermoelectric module 30 is controlled by the controller 50 and the whitening mode is performed, the swelling reduction mode in which the first main surface 31 is cooled under cooling conditions that produce the swelling reduction effect and the fat decomposition effect. It can be seen that the fat decomposition mode in which the first main surface 31 is cooled is sequentially performed under cooling conditions that generate.

The controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled to a cooling condition for reducing swelling of the user's skin.

The controller 50 may control the thermoelectric module 30 in a swelling reduction mode in which the first main surface 31 is cooled to a temperature range higher than the whitening temperature range of the whitening mode. For example, the controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled to a temperature range of 10°C to 20°C, which is higher than the whitening temperature range of the whitening mode.

The controller 50 may control the thermoelectric module 30 in a swelling reduction mode in which the first main surface 31 is cooled for a longer time than the whitening time of the whitening mode. For example, the controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled for a time ranging from 4 seconds to 20 minutes, which is longer than the whitening time of the whitening mode.

The controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled to cooling conditions for decomposing fat on the user's skin.

The controller 50 may control the thermoelectric module 30 in a fat decomposition mode in which the first main surface 31 is cooled to a temperature range higher than the whitening temperature range of the whitening mode. For example, the controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled to a temperature range of 10°C to 20°C, which is higher than the whitening temperature range of the whitening mode. Additionally, the controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled by repeatedly increasing or decreasing the temperature in a temperature range of 10°C to 20°C.

Additionally, the controller 50 may control the thermoelectric module 30 in a fat decomposition mode in which the first main surface 31 is cooled for a longer time than the whitening time in the whitening mode. For example, the controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled for a time ranging from 4 seconds to 2 hours, which is longer than the whitening time of the whitening mode.

Additionally, the controller 50 may control the thermoelectric module 30 in at least one operation mode among whitening mode, swelling reduction mode, and fat decomposition mode. For example, the controller 50 may control the thermoelectric module 30 so that the whitening mode is performed and the swelling reduction mode and fat decomposition mode are sequentially performed.

Additionally, the controller 50 may control the thermoelectric module 30 so that at least one of the swelling reduction mode and the fat decomposition mode overlaps for at least a portion of the whitening time during which the whitening mode is performed. That is, the controller 50 may control the thermoelectric module 30 so that the whitening temperature section and the temperature section of the swelling reduction mode and/or the lipolysis mode overlap for at least a portion of the whitening time during which the whitening mode is performed.

Additionally, the controller 50 can control the thermoelectric module 30 in various combinations of operation modes, such as sequentially repeating whitening mode, swelling reduction mode, and fat decomposition mode.

In addition, the controller 50 is not limited to whitening mode, swelling reduction mode, and fat decomposition mode, and can control the thermoelectric module 30 in various operation modes for skin improvement, such as skin regeneration mode and skin elasticity mode.

However, the third embodiment does not necessarily need to be implemented in the method described above, and may be implemented in various ways, such as in combination with other embodiments, depending on the situation.

<Example 4>

Below, a fourth embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described.

Referring to Figure 13, the activity of functional materials may vary depending on temperature. The temperature range at which functional substances become active may be different for each substance, and the temperature at which activity is maximum may also be different. In other words, each functional material has a different activation temperature range, which is the temperature range at which the activity is above a certain level (for example, activity above 9/10 of the maximum activity), and a maximum activity temperature, which is the temperature at which the activity is maximum. You can. For example, in the graph of Figure 13, functional material A has an activity temperature range from T1 to T4, with maximum activity at T2, and functional material B has an activity temperature range from T3 to T6, with maximum activity at T5. You can see that it has activity.

However, Figure 13 is a graph briefly illustrated for explanation purposes and is not limited thereto, and the activity of the actual functional material according to temperature may appear different from this.

Figure 14 is a graph showing the temperature change over time of the first main surface of the thermoelectric module according to the fourth embodiment of the present specification.

*Because the activity of the functional material 21 accommodated in the contact layer 20 varies depending on temperature, the temperature of the first main surface 31 is the temperature of the functional material 21 accommodated in the contact layer 20 of the user's skin. When cooled to the active temperature range, the skin improvement effect by the functional material (21) may increase.

Therefore, the controller 50 according to an embodiment of the present specification operates the thermoelectric module 30 in a functional material activation mode in which the first main surface 31 is cooled to the activation temperature range of the functional material 21 accommodated in the contact layer 20. ) can be controlled.

The controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled to the active temperature range of the functional material 21 accommodated in the contact layer 20. For example, when the active temperature range of the functional material 21 accommodated in the contact layer 20 is 0°C to 10°C, the controller 50 controls the first main surface 31 to operate at 0°C to 10°C. The thermoelectric module 30 can be controlled to cool to the C range.

In addition, the controller 50 can control the thermoelectric module 30 so that the first main surface 31 is cooled to a temperature at which the activity is maximized during the active temperature range of the functional material 21 accommodated in the contact layer 20. there is. For example, when the temperature at which the activity is maximum among the active temperature ranges of the functional material 21 accommodated in the contact layer 20 is 5°C, the controller 50 controls the first main surface 31 at 5°C. The thermoelectric module 30 can be controlled to be cooled.

Additionally, the controller 50 may control the thermoelectric module 30 to cool the first main surface 31 in the functional material activation mode to a temperature higher than the whitening temperature in the whitening mode. This is to maximize the user's skin whitening effect and prevent damage to the user's skin.

Additionally, the controller 50 may control the thermoelectric module 30 to cool the first main surface 31 in the functional material activation mode for a longer time than the whitening time in the whitening mode. This is to maximize the user's skin whitening effect and prevent damage to the user's skin.

Additionally, the controller 50 may control the thermoelectric module 30 in at least one of the whitening mode and the functional material activation mode. For example, the controller 50 may control the thermoelectric module 30 so that the whitening mode is performed and the functional material activation mode is sequentially performed.

Additionally, the controller 50 may control the thermoelectric module 30 so that the functional material activation mode overlaps for at least a portion of the whitening time during which the whitening mode is performed. That is, the controller 50 may control the thermoelectric module 30 so that the whitening temperature section and the activation temperature section of the functional material 21 overlap for at least a portion of the whitening time during which the whitening mode is performed.

Additionally, the controller 50 can control the thermoelectric module 30 in various combinations of operation modes, such as sequentially repeating the whitening mode and the functional material activation mode.

However, the fourth embodiment does not necessarily need to be implemented in the method described above, and may be implemented in various ways, such as being implemented in combination with other embodiments depending on the situation.

<Embodiment 5>

Below, a fifth embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described. Hereinafter, descriptions that overlap with the previous embodiment will be omitted. That is, technical ideas that can be used in the previous embodiment are not redundantly explained in the fifth embodiment.

Figure 15 is a graph showing the temperature change over time of the first main surface of the thermoelectric module according to the fifth embodiment of the present specification.

In order to obtain a comprehensive skin improvement effect, a plurality of functional materials 21 can be accommodated in the contact layer 20. Therefore, when a plurality of functional materials 21 are accommodated in the contact layer 20, any one functional material (21) can be accommodated in the contact layer 20. If the functional material activation mode is performed in the activation temperature range for activating 21), other functional materials may not be activated.

Therefore, in the controller 50 according to an embodiment of the present specification, when a plurality of functional materials 21 are accommodated in the contact layer 20, the first main surface 31 of the thermoelectric module 30 is connected to the contact layer 20. The first functional material activation mode is cooled to the first activation temperature range of the first functional material 21-1 and the second functional material 21-2 in which the first main surface 31 is accommodated in the contact layer 20. The thermoelectric module 30 can be controlled in a second functional material activation mode that is cooled to a second activation temperature range of ).

Referring to FIG. 15, the controller 50 cools the first main surface 31 of the thermoelectric module 30 to the first active temperature section of the first functional material 21-1 accommodated in the contact layer 20. 1 The thermoelectric module 30 is activated in a functional material activation mode and a second functional material activation mode in which the first main surface 31 is cooled to the second activation temperature range of the second functional material 21-2 accommodated in the contact layer 20. ) can be controlled.

Additionally, the controller 50 may control the thermoelectric module 30 in at least one operation mode among a whitening mode, a first functional material activation mode, and a second functional material activation mode. For example, the controller 50 may control the thermoelectric module 30 so that the whitening mode is performed and the first functional material activation mode and the second functional material activation mode are sequentially performed.

Additionally, the controller 50 may control the thermoelectric module 30 so that at least one of the first functional material activation mode and the second functional material activation mode overlaps for at least a portion of the whitening time during which the whitening mode is performed. That is, the controller 50 operates the whitening temperature section, the first active temperature section of the first functional material 21-1, and the first active temperature section of the second functional material 21-2 during at least a portion of the whitening time during which the whitening mode is performed. The thermoelectric module 30 can be controlled so that at least one of the two active temperatures overlaps.

Additionally, the controller 50 may control the thermoelectric module 30 in various combinations of operation modes, such as sequentially repeating the whitening mode, the first functional material activation mode, and the second functional material activation mode.

However, the fifth embodiment does not necessarily need to be implemented in the manner described above, and may be implemented in various ways, such as being implemented in combination with other embodiments, depending on the situation.

<Example 6>

Below, a sixth embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described. Hereinafter, descriptions that overlap with the previous embodiment will be omitted. That is, technical ideas that can be used in the previous embodiment are not redundantly explained in the sixth embodiment.

Figure 16 is a graph showing the temperature change over time of the first main surface of the thermoelectric module according to the sixth embodiment of the present specification.

After cooling of the first main surface 31 is completed due to the application of power to the thermoelectric module 30 of the controller 50, if the power to the thermoelectric module 30 is cut off through the controller 50, the second main surface 32 Due to the heat generated from the thermoelectric module 30, the temperature rises and quickly approaches the high temperature of the second main surface 32. At this time, if heat is suddenly applied to the user's skin, which has been cooled to a low temperature through the thermoelectric module 30 whose temperature has risen, the user may feel relatively great discomfort due to the heat, and skin damage may occur due to the high temperature.

Therefore, the controller 50 according to an embodiment of the present specification is configured to operate the first main surface 31 after the cooling of the first main surface 31 is completed (for example, after the whitening mode, functional material activation mode, etc. are completed) until the user removes the mask. The thermoelectric module 30 can be controlled so that the temperature of 31 does not rise rapidly. Referring to FIG. 16, after the whitening mode in which the first main surface 31 is cooled to a cooling temperature of 5°C for 100 seconds is completed, the thermoelectric module 30 is controlled by the controller 50 to gradually cool the first main surface 31. It can be seen that a desorption mode in which the temperature rises is performed. Hereinafter, the detachment mode refers to the controller 50 controlling the temperature of the first main surface 31 after cooling of the first main surface 31 is completed (after the end of the operation mode).

The controller 50 operates the thermoelectric module ( 30) can be controlled. For example, the controller 50 may control the thermoelectric module 30 so that the temperature of the first main surface 31 increases by 0.3°C per second after cooling of the first main surface 31 is completed.

Additionally, the controller 50 may control the thermoelectric module 30 in a desorption mode that maintains the temperature of the first main surface 31 at a constant temperature after cooling of the first main surface 31 is completed. For example, the controller 50 may control the thermoelectric module 30 to gradually increase the temperature of the first main surface 31 to reach a temperature of 5°C to 30°C. Alternatively, the controller 50 may control the thermoelectric module 30 to maintain the temperature of the first main surface 31 after cooling of the first main surface 31 is completed.

Additionally, the controller 50 may control the thermoelectric module 30 to maintain the detachment mode for a certain period of time to provide sufficient time for the user to remove the mask 10 while the detachment mode is being performed. For example, the controller 50 may control the thermoelectric module 30 to perform the desorption mode in the range of 10 seconds to 5 minutes.

Additionally, the controller 50 may control the thermoelectric module 30 so that the desorption mode ends when a signal for detaching the mask 10 from the user is obtained. For example, the controller 50 may control the thermoelectric module 30 to terminate the detachment mode when a power-off signal is input from the user or a signal of the user's skin not being detected is obtained through the touch sensor.

Additionally, the controller 50 can control the output unit to output a notification when the detachment mode starts or ends. For example, the controller 50 may control the output unit so that when the removal mode starts, the output unit outputs a vibration or a voice message notifying the mask removal. Alternatively, the controller 50 may control the vibration generator to output vibration through the vibration generator when the attachment/detachment mode starts or ends.

However, the sixth embodiment does not necessarily need to be implemented in the method described above, and may be implemented in various ways, such as in combination with other embodiments, depending on the situation.

<Additional Example>

Hereinafter, various additional embodiments in which the controller 50 controls the mask 10 will be described. Hereinafter, descriptions that overlap with the previous embodiment will be omitted. That is, technical ideas that can be used in the previous embodiments will not be redundantly explained in the additional embodiments below.

Since the cooling conditions under which the optimal whitening effect is achieved are different for each individual, the mask 10 may cool the user's skin under cooling conditions that are different for each individual to achieve the optimal whitening effect.

Therefore, the controller 50 according to an embodiment of the present specification may control the thermoelectric module 30 to perform an operation mode set by the user other than the preset operation mode. Alternatively, the controller 50 may control the thermoelectric module 30 to perform an operation mode in which a preset operation mode is arbitrarily modified.

The controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled under the cooling conditions input from the input unit 52. For example, the controller 50 determines the cooling conditions of the first main surface 31 (cooling time of the first main surface 31, cooling temperature of the first main surface 31, cooling sequence, cooling condition) received from the input unit 52. The control module 30 can be controlled so that the first main surface 31 is cooled according to data about the area (part, etc.).

Additionally, the controller 50 may control the thermoelectric module 30 to cool the first main surface 31 according to cooling conditions obtained from an external device through the communication unit 51. For example, the controller 50 obtains the cooling conditions of the first main surface 31 from an external device through the communication unit 51 (cooling time of the first main surface 31, cooling temperature of the first main surface 31, The control module 30 can be controlled so that the first main surface 31 is cooled according to data regarding (cooling order, cooling area, etc.).

However, although the above-described embodiments have been described with limited examples and drawings, those skilled in the art can make various modifications and variations from the above description. For example, appropriate results may be achieved even if the described techniques are performed in a different order than the described method or under different conditions.

Heat generated from the main surface 31 can be dissipated. For example, when the mask 10 is mounted on the holder 60, the mask 10 is cooled to below the melting point of the phase change material containing the heat dissipation layer 40 through the second main surface 32 and the holder ( 60) can radiate heat generated from the first main surface 31 through a separate fan or thermoelectric module.

According to another embodiment, the holder 60 is provided so that the heat dissipation layer 40 is in contact with one surface of the holder 60, and when the mask 10 is mounted on the holder 60, a separate heat dissipation means is used. The heat dissipation layer 40 can be cooled through this. For example, when the mask 10 is mounted on the holder 60, the holder 60 is lower than the melting point of the phase change material contained in the heat dissipation layer 40 through a thermoelectric module disposed on one side of the holder 60. The heat dissipation layer 40 can be cooled.
