Abstract

PURPOSE: A cooling and heating device is provided to ventilate air via an evaporator into a vehicle by passing through a heater or without passing through the heater by forming door members to be opened and closed crosswise. CONSTITUTION: A door member(21) comprises many rotating doors(23) and link rods(24). The rotating doors(23) have rotating shafts(22) and door shafts(25) to alternatively open and close each door by forming between an evaporator and a heater. The link rods are fixed in the door shafts to separately fix the rotating doors at regular intervals. A rotating support is fixed in one rotating shaft among the rotating doors in each door member. Each rotating support is fixed by a door opening/closing lever. Thereby, the size and the weight of a heater-vent-air conditioning module are reduced. Moreover, the reserve space between the evaporator and the heater is formed and the operating required force of the door members is reduced.

Description

Car air conditioning unit {THE AIR CONDITIONING DEVICE FOR CAR}

The present invention relates to a vehicle heating and cooling device, and more particularly, in order to allow the air passing through the evaporator to be discharged into the vehicle after passing through the heater, or to be discharged directly into the vehicle without passing through the heater, between the evaporator and the heater. It is provided in the upper and lower sides, by installing the door member to be opened and closed alternately, relates to a vehicle air conditioning device, characterized in that to reduce the volume of the air conditioning device and maximize the space utilization.

The heating and cooling device of an automobile is used to provide a comfortable environment to the occupant by appropriately maintaining an air environment such as temperature and humidity in accordance with the change of the ambient temperature.

FIG. 1A is a state sectional view of a vehicle air conditioner that delivers a conventional low temperature air, and FIG. 1B is a state sectional view of a vehicle air conditioner that delivers a high temperature conventional air.

As shown, the blower fan 11, the evaporator 12 and the heater 13 are disposed inside the HVAC module 10, the blower fan 11 is located in front of the air flow direction, It serves to push external or internal air toward the evaporator 12 and the heater 13.

An evaporator 12 is arranged behind the blower fan 11, and the evaporator 12 cools the air by absorbing heat contained in the air by using a refrigerant condensed in the condenser and expanded in the expansion valve. do.

In addition, the heater 13 is located behind the evaporator 12. The heater 13 cools the cylinder block of the engine and heats the air by conducting heat to the air using heated hot coolant.

At this time, a blowing temperature control door 14 is provided between the evaporator 12 and the heater 16, and the blowing temperature control door 14 opens or closes the heater chamber 17 to be discharged to the blower 18. The temperature of the air being controlled.

That is, if the low temperature air is to be discharged to the blower 18, the blower temperature control door 14 closes the heater chamber 17 to prevent the air passing through the evaporator 12 from passing through the heater 13. In addition, the high temperature discharge door 15 is also closed, and the air passing through the evaporator 12 is discharged to the blower opening 18 in which the blower door 16 is opened.

And, if the hot air is to be discharged to the blower 18, the blowing temperature control door 14 opens the heater chamber 17 so that the air passing through the evaporator 12 passes through the heater 13, The high temperature discharge door 15 is also opened, and the air passing through the evaporator 12 passes through the heater 13 and then is discharged to the blower opening 18 in which the blower door 16 is opened.

However, when opening and closing the blower temperature control door 14 for temperature control, the length of the blower temperature control door 14 is long, so that the use of space due to the moving trajectory is excessive, so that the overall size and volume of the vehicle air conditioner are increased. It becomes large and there is a problem that the operation required force of the blowing temperature control door 14 also becomes large.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to open and close alternately while the air passing through the evaporator is formed up and down so as to be discharged into the vehicle without passing through the heater or through the heater. It relates to a vehicle heating and cooling device characterized in that the door member is provided.
