Air-conditioning ventilation seat module for vehicles

Abstract

An air-conditioning ventilation seat module for vehicles, may include a blower unit having a housing, a thermoelectric module having a casing mounted in the housing, wherein a thermoelectric device may be mounted in the casing, and wherein an internal space of the casing may be divided into a cold air path and a hot air path, a separator connected to one side of the thermoelectric module between the cold air path and the hot air path and having a curved section in order to maximize an amount of absorbing a condensate that may be created by a temperature difference between the cold air path and the hot air path when the seat module operates in cooling mode.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to Korean Patent Application No. 10-2010-0125670 filed on Dec. 9, 2010, the entire contents of which is incorporated herein for purposes by this reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates, in general, to an air-conditioning ventilation seat for vehicles and, more particularly, to an air-conditioning ventilation seat for vehicles, in which in an air-conditioning mode, an amount of absorbing condensate is maximized.[0004]2. Description of Related Art[0005]Generally, vehicles are provided with an air conditioner, which includes a cooler and a heater, in order to regulate the temperature of the interior of a vehicle. However, such an air conditioner does not have the function of regulating the temperature of vehicle seats, so that for instance in the summer, although the temperature of vehicle interior is lowered by the operation of the air co...

AI Technical Summary

Benefits of technology

[0013]In an aspect of the present invention, the air-conditioning ventilation seat module for vehicles, may include a blower unit having a housing, a thermoelectric module having a casing mounted in the housing, wherein a thermoelectric device may be mounted in the casing, and wherein an internal space of the casing may be divided into a cold air path and a hot air path, a separator connected to one side of the thermoelectric module between the cold air path and the hot air path and having a curved section in order to maximize an amount of absorbing a condensate that may be created by a temperature difference between the cold air path and the hot air path when the seat module operates in cooling mode.

[0022]As set forth before, according to the construction of the invention, condensate that is created from the thermoelectric module in cooling mode can be removed, thereby preventing operational error of the thermoelectric module due to the condensate, and improving the air conditioning efficiency irrespective of factors associated with the creation of condensate.

Problems solved by technology

However, such an air conditioner does not have the function of regulating the temperature of vehicle seats, so that for instance in the summer, although the temperature of vehicle interior is lowered by the operation of the air conditioner, the vehicle seat is not sufficiently cooled and if a passenger is sitting thereon, because of the passenger's heat, the sweat of the passenger may make his hips and backs moist, and cause him to suffer from heat rash.

Also in winter, although operating the heater drives up the temperature of the interior of a vehicle, the vehicle seat does not sufficiently heat up, but stays cold, so that the hips and back of a passenger who is sitting thereon feels cold.

However, such a conventional air conditioner for a vehicle seat has drawbacks in that upon cooling, the temperature of the thermoelectric semiconductor modules 19 and 20, which serve as a heater, is lower than that of the air in the vehicle interior, causing the air to condense into moisture, which when introduced into the modules 19 and 20, reduces the cooling efficiency so that for instance a passenger sitting on the vehicle seat does not feel sufficiently cold, and leads to operational errors.

Further, while a conventional air conditioner of a vehicle generally has a drain structure through which moisture is discharged out of a vehicle, in the above air conditioner for a vehicle seat, a ventilation module is mounted in the vehicle, making it difficult to discharge moisture out of the vehicle due to restrictions in the installation of the drain structure.
