By the way, in the beauty device as described above, there is a demand to add a function of warming the contact portion in order to provide comfort to the user. At that time, a device for reducing energy consumption was desired.

The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a beauty device capable of reducing energy consumption while having a function of warming the contact portion.

A beauty device of the present invention is a beauty device that is held and used, and includes a contact portion that is brought into contact with the skin, a detection portion that detects a state in which the beauty device is in contact with a user, and detection by the detection portion. Based on the results, the contact portion is set to the first target temperature when the beauty device is not in contact with the user, and the contact portion is set to the first target temperature when the beauty device is in contact with the user. a control unit for setting a second target temperature higher than the target temperature.

The state in which the beauty device is not in contact with the user and the state in which the beauty device is in contact with the user include the following patterns. That is, the state in which the beauty device is not in contact with the user is the state in which the beauty device is not gripped, and the state in which the beauty device is in contact with the user is the state in which the beauty device is gripped but the contact portion is not in contact with the user. Includes patterns that are not in contact with the skin. A state in which the beauty device is not in contact with the user is a state in which the beauty device is not gripped, and a state in which the beauty device is gripped but the contact portion is not in contact with the skin.

Next, an example of the operation of the beauty device 10 of this embodiment will be described.
First, an example of the operation of the beauty device 10 in the first mode will be described with reference to the flowchart of FIG.

When the user operates the switch unit 16 to turn on the power (S100), the control unit 15 starts measuring the elapsed time after the power of the beauty device 10 is turned on. Then, when the user selects the first mode (S101), the control unit 15 heats the first heating element 31 to raise the first contact portion 12 to the first target temperature (38 degrees in this embodiment). warm (S102). At this time, if the temperature of the first contact portion 12 before turning on the power is 15 degrees, the control portion 15 controls the temperature so that the first contact portion 12 reaches the first target temperature in about one minute. to rapidly heat the first heating element 31. Also, although not shown in the flowchart, the control unit 15 heats the second heating element 34 to raise the second contact portion 13 to a standby temperature (30 degrees in this embodiment) lower than the first target temperature. During this time, the control unit 15 slowly blinks the first light emitting unit 21 in white, turns on the second light emitting unit 22, and keeps the third light emitting unit 23 and the fourth light emitting unit 24 turned off.

When the first contact portion 12 reaches the first target temperature, the controller 15 maintains the first contact portion 12 at the first target temperature (S103), and the beauty device 10 enters a standby state. The control unit 15 stops heating when the first contact portion 12 reaches the first target temperature or higher, and heats the first contact portion 12 when the first target temperature or lower, and maintains the first contact portion 12 at the first target temperature. The control unit 15 continues to slowly blink the first light emitting unit 21 in white, turn on the second light emitting unit 22, and keep the third light emitting unit 23 and the fourth light emitting unit 24 turned off.

When the time elapsed since the power of the beauty device 10 was turned on exceeds a predetermined time (5 minutes in this embodiment) (S104: Yes), the control unit 15 automatically turns off the power (S108). The control unit 15 turns off all the light emitting units 21 , 22 , 23 , 24 and stops heating the first heating element 31 and the second heating element 34 . As a result, it is possible to prevent a situation in which the beauty device 10 is left on for a predetermined time or more, and wasteful consumption of energy can be prevented.

The user does not start using it, that is, the beauty device 10 in the standby state is left without being gripped, or the beauty device 10 in the standby state is gripped but the first contact part 12 is not brought into contact with the skin. If the skin is still not detected (S105: No), the controller 15 maintains the temperature of the first contact portion 12 at the first target temperature.

When the user holds the beauty device 10 in the standby state and applies the first contact portion 12 to the skin before a predetermined time has passed since the power of the beauty device 10 was turned on (S104: No), A current flows through the first contact portion 12 and the detection portion 14 detects it (S105: Yes), and the control portion 15 starts the operation in the first mode (S106). Here, when the user puts the first contact portion 12 against the skin, the first contact portion 12 is at the first target temperature. Since the first target temperature in this embodiment is 38 degrees, which is equivalent to the human body temperature, it is possible to eliminate coldness when the first contact portion 12 is brought into contact with the skin. Also, the control unit 15 resets the timer started when the power of the beauty device 10 is turned on, and instead starts measuring the elapsed time after the first contact portion 12 is brought into contact with the skin.

When the operation in the first mode is started, the control section 15 heats the first heating element 31 to raise the temperature of the first contact section 12 to the second target temperature (41 degrees in this embodiment). At this time, the controller 15 raises the temperature of the first contact portion 12 from the first target temperature to the second target temperature at a speed slower than the speed of raising the temperature of the first contact portion 12 to the first target temperature. This can reduce the stress on the user's skin. In addition, if the temperature is rapidly increased, there is a risk of causing a so-called overshoot in which the first heating element 31 is excessively increased, but such an excessive increase in temperature can be prevented. The controller 15 applies a first current to the first contact portion 12 to drive the first vibration motor 33 . A user senses that the first mode is operating from the vibration of the first vibration motor 33 . The control unit 15 keeps the second contact part 13 at the standby temperature, continuously blinks the first light emitting part 21 slowly in white, turns on the second light emitting part 22, and turns on the third light emitting part 23 and the fourth light emitting part. 24 remains unlit.

When the time elapsed since the first contact portion 12 was brought into contact with the skin exceeds a predetermined time (5 minutes in this embodiment) (S107: Yes), the control unit 15 automatically turns off the power (S108 ). The control unit 15 turns off all the light emitting units 21 , 22 , 23 , 24 and stops heating the first heating element 31 and the second heating element 34 . The control unit 15 maintains the operation in the first mode until a predetermined time elapses after the first contact unit 12 is brought into contact with the skin (S107: No).

Next, an example of the operation of the beauty device 10 in the second mode will be described with reference to the flowchart of FIG.
When the user operates the switch unit 16 to turn on the power (S200), the control unit 15 starts measuring the elapsed time after the power of the beauty device 10 is turned on. Then, when the user selects the second mode (S201), the control unit 15 heats the second heating element 34 to raise the second contact portion 13 to a predetermined treatment temperature (30 degrees in this embodiment). warm (S202). The treatment temperature in the second mode (the mode in which the second current is passed through the second contact portion 13) is the treatment temperature (41 degrees) suitable for the first mode (the mode in which the first current is passed through the first contact portion 12). slightly lower temperature. Although not shown in the flowchart, the control unit 15 heats the first heating element 31 to raise the first contact portion 12 to the standby temperature (30 degrees). The standby temperature of the first contact portion 12 is the same temperature as the standby temperature of the second contact portion 13 in the first mode. During this time, the control unit 15 slowly blinks the first light emitting unit 21 in blue, turns on the third light emitting unit 23, and turns off the second light emitting unit 22 and the fourth light emitting unit 24.

When the temperature of the second contact portion 13 rises to the predetermined treatment temperature, the control portion 15 maintains the second contact portion 13 at the predetermined treatment temperature (S203), and the beauty device 10 enters a standby state. The control unit 15 stops heating when the second contact portion 13 reaches a predetermined treatment temperature or higher, and heats when the second contact portion 13 falls below the predetermined treatment temperature to keep the second contact portion 13 at the treatment temperature. The control unit 15 continues to slowly blink the first light emitting unit 21 in blue, turn on the third light emitting unit 23, and keep the second light emitting unit 22 and the fourth light emitting unit 24 turned off. Further, when the time elapsed since the power of the beauty device 10 was turned on exceeds a predetermined time (5 minutes in this embodiment) (S204: Yes), the control unit 15 automatically turns off the power (S208). . The control unit 15 turns off all the light emitting units 21 , 22 , 23 , 24 and stops heating the first heating element 31 and the second heating element 34 . Thus, as in the first mode, it is possible to prevent the cosmetic device 10 from being left on for a predetermined time or more, and wasteful energy consumption can be prevented.

The user does not start using, that is, the beauty device 10 in the standby state is left without being gripped, or the beauty device 10 in the standby state is gripped but the second contact part 13 is not brought into contact with the skin. If the skin is still not detected (S205: No), the control unit 15 maintains the second contact unit 13 at the treatment temperature.

When the user holds the beauty device 10 in the standby state and applies the second contact portion 13 to the skin before a predetermined time has elapsed since the power of the beauty device 10 was turned on (S204: No), A current flows through the second contact portion 13 and the detection portion 14 detects it (S205: Yes), and the control portion 15 starts the operation in the second mode (S206). In addition, the control unit 15 resets the timer started when the power of the beauty device 10 is turned on, and instead starts measuring the elapsed time after the second contact portion 13 is brought into contact with the skin. The control unit 15 applies the second current to the second contact portion 13 while maintaining the temperature of the second contact portion 13 at a predetermined treatment temperature, and drives the second vibration motor 36 . A user senses that the second mode is operating by the vibration of the second vibration motor 36 . During this time, the control unit 15 keeps the temperature of the first contact part 12 at the standby temperature, lights the first light emitting part 21 in blue, lights the third light emitting part 23, lights the second light emitting part 22 and the fourth light emitting part. The part 24 is kept in the extinguished state.

When the elapsed time after the second contact portion 13 is brought into contact with the skin exceeds a predetermined time (5 minutes in this embodiment) (S207: Yes), the control portion 15 automatically turns off the power. Turn off (S208). Also, the control unit 15 turns off all the light emitting units 21 , 22 , 23 , 24 and stops heating the first heating element 31 and the second heating element 34 . The control unit 15 maintains the operation in the second mode until a predetermined time has elapsed since the second contact portion 13 was brought into contact with the skin (S207: No).

Next, an example of operation of the beauty device 10 in the third mode will be described with reference to the flowchart of FIG.
When the user operates the switch unit 16 to turn on the power (S300), the control unit 15 starts measuring the elapsed time after the power of the beauty device 10 is turned on.
