Seat-air conditioner

FIELD: transport.

SUBSTANCE: invention deals with devices that improve comfort of passengers and drivers. Seat-air conditioner includes seat, hollow stole with perforated surface, air blower located under the seat. Under the seat there is vortex tube connected with air blower and control device that consists of an element made of material with shape memory effect. In winter time control device supplies warm air into hollow stole and cold air - outside, in summer time it supplies warm air outside and cold air - into hollow stole. In hollow stole there can be located flexible foamed material providing uniform air passing. Pipes supplying air into hollow stole are equipped with return valves.

The invention relates to vehicles, and more particularly, to means of increasing the comfort of the vehicle.

Known seat in the cab, including the chair, to which is attached a hollow cloak with a perforated outer surface communicating with a blower installed in the space under the seat, which improves the comfort of the vehicle [1].

A disadvantage of the known seat is that it is controlled manually.

The technical result, which directed the claimed invention is the provision of an automatic control device.

To achieve the technical result in the vehicle seat including a seat, a hollow cloak with a perforated surface, a blower placed in the space under the seat according to the invention in the space under the seat is mounted vortex tube connected to the blower, and a control device with an element from a material with shape memory effect, which in the cold directs warm air into the hollow cloak, and cold outside, and in the warm season warm air out and cold - cavity Cape.

In addition, the hollow cloak placed elastic porous material provides a uniform passage of air.

In addition, pipes and, the air enters the hollow Cape, have a check valve.

The invention is illustrated by drawings, which presents the seat air-conditioning system during operation: figure 1 - in the cold season, and in figure 2 - in warmer.

We offer seat-air conditioning includes a seat 1, a fixed hollow cloak 2, filled with an elastic porous material, a vortex tube 3, and a control device including the element 4 made of a material with shape memory effect, and the rods 5 and 6, mounted on the element 4 and pivotally connected to the movable tubes 7 and 8. Transition point temperature of the material of element 4 corresponds to the optimal temperature, for example 20°C. In cold temperature control device has a maximum length, when warm - minimal.

The blower 9 through the filter 10 communicates with the outer atmosphere, and through the pipe 11 from the vortex tube 3. Mobile tube 7 communicates with the pipe 12 cold air from the vortex tube 3. She is the managing device may be connected either with the discharge tube 13, or with a pipe 14 communicating with the internal cavity of the cushion 2. Mobile tube 8 communicates with the pipe 15 hot air, and the control device may be connected with the discharge pipe 17 or tube 18 communicating with the internal cavity of NAC is DKI 2. When this tube 14 and 18 are provided with check valves that let the air just inside the capes 2.

The device operates as follows. It turns on by applying voltage to the blower 9. The blower 9 through the air filter 10 sucks outside air through the pipe 11 supplies it to a vortex tube 3, where the air is divided into two streams: cold through the pipe 12 and the hot - pipe 15.

During hot weather, the element 4 is deployed, the control device receives the minimum length, moving the end of the movable tube 7 for connection with a pipe 14 through which cold air enters the inside of the cushion 2, and the end of the movable tube 8 for connection with a pipe 17, through which the hot air goes out. From capes 2 through the perforated surface of the cold air is evenly distributed in the cabin (or beauty), creating a pleasant coolness (figure 1).

During the cold weather element 4 decreases, the control device receives the maximum length of the moving end of the movable tube 8 for connection with a pipe 18, through which the hot air enters the inside of the cushion 2, and the end of the movable tube 7 - connection pipe 13, through which the cold air goes out. From capes 2 through its perforated surface of the hot air is evenly distributed in the cabin is whether in the salon), creating warmth and comfort (figure 2).

In the case of a change of temperature of the air inside the vehicle control device automatically changes the direction of flow of cold and hot air, providing in the cockpit (or beauty) optimum temperature.
