Chair capable of adjusting temperature

Technical Field

The utility model relates to the field of seats, in particular to a seat capable of adjusting temperature.

Background

Chairs are sitting on, typically having two parts, a seat plate and a backrest, some chairs also having chair feet supporting the seat plate. In many cases, in order to make people feel comfortable, a cushion is generally placed on the seat board and the back board of the flat board, so that people feel comfortable when sitting for a long time, and some cushion with elasticity is directly fixed into the seat board and the back board, such as automobile seats, because people need to sit for a long time when sitting on the automobile, many automobile seats, especially seats of drivers in driving cabins, are soft seats, in which the seat board (seat cushion) and the back board (back board) are internally provided with elastic cushions, and the outer surfaces of the soft seats are covered with leather or other fabrics to form a surface cover for people to sit or lean on, so that people feel comfortable when sitting on the soft seats for a long time.

Since such a soft seat like a sofa forms a contact portion of the largest area according to the shape of the buttocks and the back of a person when sitting on such a seat, the person is particularly sensitive to the temperature of the seat itself when sitting on such a seat, for example, when the car is just started in winter, the temperature in the car is low, and at this time, the person sitting on the soft seat in the car feels very cold, so many car seats are provided with heating devices at present, and in a cold season, the person sits on the car just started, the car is heated, and at this time, heating wires are generally added in the filler in the seat cover, so that the person sits on the car like an electric blanket, and after a while the temperature in the car rises, the seat cover is added with a certain heat insulation property, and therefore, the heating can be stopped.

However, in the hot season, the automobile can shine to the seats in the automobile when the automobile is stopped under the sun, so that the temperature of the seat covers is particularly high, at the moment, people wear the automobile in a very thin way, if people sit on the automobile, the automobile can give a very poor experience, therefore, in many times, the automobile air conditioner needs to be started to cool the interior of the automobile, the covers on the seat surfaces are slowly cooled, the cooling time is long, and the poor experience is brought to people.

The utility model patent publication No. CN 210101408U discloses a heating and refrigerating pad, which comprises a supporting piece, a refrigerating and heating component, a conducting strip and a pad body; the pad body is positioned above the conducting sheet, and is contacted with the body of a user and used for supporting the user; the support member supports the conductive sheet and the pad body; the refrigerating and heating assembly is connected with the conducting piece, and the refrigerating and heating assembly heats or refrigerates the pad body through the conducting piece. The heating and refrigerating cushion is heated or cooled rapidly, and is arranged in a vehicle to be used as a seat cushion or a back cushion of the vehicle, so that passengers or drivers can not feel uncomfortable in winter or summer. However, when the cooling and heating assembly heats or refrigerates the pad body through the conductive sheet, at present, since the pad body is generally a non-good conductor of heat such as cotton cloth, it is difficult to satisfy that the cooling and heating assembly can cool the pad body rapidly through the conductive sheet, and the temperature of the pad body is reduced.
