SEAT TEMPERATURE REGULATOR
A seat temperature regulator includes a control device capable of controlling a temperature of a seat for heating and cooling. The control device continuously repeats the heating and cooling within a temperature width range of 10° C. or less.
1 . A seat temperature regulator comprising:
a control device capable of controlling a temperature of a seat for heating and cooling,
the control device continuously repeating the heating and cooling within a temperature width range of 10° C. or less.
2 . The seat temperature regulator of claim 1 , wherein the control device continuously repeats the heating and cooling within a temperature width range of 4° C. or less.
3 . The seat temperature regulator of claim 1 , wherein, after cooling the seat, the control device continuously repeats the heating and cooling at a temperature equal to or less than a temperature before cooling.
4 . The seat temperature regulator of claim 1 , wherein the control device sets a lower limit temperature to 20° C., while setting an upper limit temperature to 30° C., and continuously repeats the heating and cooling at a change rate of 1° C./minute or more between the upper limit temperature and the lower limit temperature.
5 . The seat temperature regulator of claim 1 , wherein the control device sets a lower limit temperature to 22° C., while setting an upper limit temperature to 26° C., and continuously repeats the heating and cooling at a change rate of 3° C./minute or more between the upper limit temperature and the lower limit temperature.
6 . The seat temperature regulator of claim 1 , further comprising:
a Peltier element connected to the control device, wherein
the heating and cooling of the seat is performed by the Peltier element.
7 . The seat temperature regulator of claim 1 , further comprising:
at least one sensor that detects sleepiness of a user; and
a determination device that determines a sleepiness level of the user based on information from the at least one sensor, wherein
the control device performs control based on information from the determination device.
8 . The seat temperature regulator of claim 6 , further comprising:
a first heat conducting sheet that is in contact with the Peltier element; and
a second heat conducting sheet that is in contact with the Peltier element, wherein
the Peltier element has a first surface and a second surface that face each other in a predetermined direction,
the first heat conducting sheet has:
a first portion that is in contact with the first surface of the Peltier element; and
a second portion that is located to be farther from the Peltier element than the first surface in the predetermined direction,
the second heat conducting sheet has:
a third portion that is in contact with the second surface of the Peltier element; and
a fourth portion that is located to be opposite of the second surface from the Peltier element in the predetermined direction.
9 . The seat temperature regulator of claim 8 , wherein the fourth portion of the second heat conducting sheet is in line with the second portion of the first heat conducting sheet in a plan view from the predetermined direction.
10 . The seat temperature regulator of claim 1 , further comprising:
a discomfort sensor that detects discomfort of a user; and
a discomfort determination device that detects a discomfort level of the user based on information from the discomfort sensor, wherein
the control device performs control based on information from the discomfort determination device.
11 . The seat temperature regulator of claim 10 , wherein examples of the discomfort sensor include a pressure sheet sensor capable of acquiring a contact pressure between the user and the seat.
12 . The seat temperature regulator of claim 10 , wherein examples of the discomfort sensor include a user attitude monitor that detects an attitude of the user.
13 . The seat temperature regulator of claim 10 , wherein when the discomfort level is equal to or more than a threshold, the control device reduces a temperature width between an upper limit temperature and a lower limit temperature of temperature regulation that continuously repeats the heating and cooling to be less than a temperature width before the discomfort determination device determines the discomfort level.
14 . The seat temperature regulator of claim 6 , further comprising:
a heat conducting sheet that is in contact with the Peltier element; and
a fan that radiates heat from the heat conducting sheet.
15 . The seat temperature regulator of claim 14 , further comprising a heat dissipation fin that is arranged between the heat conducting sheet and the fan.
16 . The seat temperature regulator of claim 1 , wherein the control device continuously repeats the heating and cooling such that a length of a heating period is different from a length of a cooling period.
17 . The seat temperature regulator of claim 1 , wherein the control device continuously repeats the heating and cooling such that a length of a heating period is identical to a length of a cooling period.
18 . The seat temperature regulator of claim 1 , wherein the control device continuously repeats the heating and cooling such that a change rate of heating is different from a change rate of cooling.
19 . The seat temperature regulator of claim 1 , wherein the control device continuously repeats the heating and cooling such that a change rate of heating is identical to a change rate of cooling.
20 . The seat temperature regulator of claim 1 , wherein the control device further includes a notification device that gives a notification of a start of temperature regulation that continuously repeats the heating and cooling in advance.
