Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automotive air conditioner, and more particularly to a vertical integrated air conditioner in which an evaporator (condenser, cooling heat exchanger) and a heater core (heating heat exchanger) are arranged in an integrated unit.
[0002]
[Prior art]
With the background of the improvement in the cooler mounting rate, particularly in passenger car air conditioners, it has been studied to store the evaporator and the heater core in one unit and eliminate the conventional cooler unit. In contrast to a conventional horizontal air conditioner in which an intake unit, a cooler unit, and a heater unit are arranged in a horizontal row in the left-right direction of the vehicle, this type of automobile air conditioner is often referred to as a vertical integrated air conditioner. .
[0003]
By combining the cooler unit and the heater unit into one unit, not only the foot space in the vehicle compartment is expanded, but also the material, manufacturing and assembly costs can be reduced by integrating the units.
[0004]
As a conventional vertical integrated air conditioner, an evaporator and a heater core are substantially upright and arranged in the front-rear direction of the vehicle (see, for example, Japanese Utility Model Publication No. 57-5,318), or an evaporator and a heater core are substantially horizontal. In this manner, a vehicle arranged in the vertical direction of the vehicle (see, for example, Japanese Patent Laid-Open No. 8-104,129) is known.
[0005]
As shown in FIG. 6, the former air conditioner is provided with an air conditioning unit casing 31 with an evaporator 32 and a heater core 33 in a substantially upright state, and the intake air from the intake unit is supplied to an inlet 40 located in front of the vehicle. Into the casing 31. A mix door 34a, a submix door 34b, and a bypass passage 35 are provided between the evaporator 32 and the heater core 33, and a vent outlet 37, a defrost outlet 38, and a foot outlet 39 are provided above the bypass passage 35. Is formed.
[0006]
In this type of air conditioner, the air introduced from the inlet 40 flows toward the rear of the vehicle in the order of the evaporator 32 and the heater core 33. “37D” is a vent door, “38D” is a differential door, and “39D” is a foot door.
[0007]
[Problems to be solved by the invention]
However, the conventional vertical integrated air conditioner shown in the figure has a structure in which the back space (warm air passage) 41 of the heater core 33 and the air mix chamber C are always in communication. Even if 34a is fully closed, the warm air heated by the back surface of the heater core 33 naturally rises, and this is mixed with cold air in the air mix chamber C, resulting in a problem that the cooling capacity is lowered.
[0008]
However, this problem can be solved by attaching a hot water valve to the hot water pipe of the heater core 33 and closing the hot water valve at the time of cooling. However, if this is done, the hot water valve will increase, parts costs, incidental parts costs or assembly man-hours, etc. Increase, which is not preferable in terms of cost.
[0009]
The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a vertical integrated air conditioner that can prevent a reduction in cooling performance due to warm air from a heater core at a low cost.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a mounted state of an automotive air conditioner of the present invention, and FIG. 2 is a longitudinal sectional view showing an embodiment of an automotive air conditioning unit of the present invention.
[0024]
As shown in FIG. 1, an automotive air conditioner 100 according to this embodiment includes an intake unit 10 and an air conditioning unit 30, and includes an intake unit casing 11 and an air conditioning unit casing 31, respectively, which are ducts (not shown). Connected with. These units 10 and 30 are mounted in the left-right direction along the dash panel DP in the instrument panel IP of the vehicle. Although not particularly limited, the intake unit 10 is attached to the back of the instrument panel IP located at the foot of the passenger seat, and the air conditioning unit 30 is attached to the back of the center console CC located in the center of the vehicle. The left-hand drive vehicle is mounted symmetrically with FIG.
[0025]
The intake unit casing 11 is formed with an outside air inlet 12 for taking in air outside the passenger compartment and an inside air inlet 13 for circulating indoor air. The inside air inlet 13 is directly formed in the intake unit case 11, but the outside air inlet 12 is communicated with an inlet formed in the cowl panel of the vehicle body via an air duct (both not shown). ing.
[0026]
Although not shown, the intake unit case 11 is provided with an intake door so as to be rotatable, and a position where the outside air inlet 12 is fully closed (inside air circulation mode) and a position where the inside air inlet 13 is fully closed (outside air). (Intake mode) and, if necessary, stop at the intermediate position (inside / outside air intake mode). The rotation of the intake door is performed by an intake door actuator attached to the intake unit case 11 or a manual wire. The intake of the inside air and / or the outside air is performed by a fan that is rotated by a fan motor.
[0027]
As shown in FIG. 2, the air conditioning unit casing 31 is formed with an inlet 40 for air blown from the intake unit 10 through a duct, on the vehicle front side of the side surface of the casing 31. 2 is a longitudinal sectional view when the air conditioning unit 30 is viewed from the passenger seat side in FIG.
[0028]
In the vicinity of the inlet 40, an evaporator 32 for cooling the intake air is provided substantially upright and with the air passage surface 32a facing the vehicle front-rear direction. The evaporator 32 is an element of a cooling cycle that is configured by connecting a compressor, a condenser (evaporator), an expansion valve, a liquid tank, and the like with a refrigerant pipe. In addition, since main components such as a compressor, a condenser, and a liquid tank are provided in the engine room, these and the evaporator 32 are connected through the dash panel DP by refrigerant piping. The cooling cycle is operated and stopped by an air conditioner switch on a control panel provided on the instrument panel IP in the passenger compartment.
[0029]
On the vehicle rear side of the evaporator 32 in the air conditioning unit case 31, a heater core 33 is provided substantially upright so as to form a bypass path 35. The heater core 33 is also disposed with its air passage surface 33a facing in the vehicle front-rear direction. The engine cooling water of the vehicle circulates in the heater core 33, and the air is heated by heat exchange between the engine cooling water and the air.
[0030]
In particular, in the air conditioning unit 30 of the present embodiment, as described later, a measure against warming up at the time of a full cool is taken, so that a warm water valve provided in the engine cooling water pipe can be omitted.
[0031]
In the air conditioning unit 30 of the present embodiment, two mix doors 34 a and 34 b are provided between the evaporator 32 and the heater core 33. The first mix door 34 a located on the lower side of the vehicle exclusively controls the amount of air flowing down to the heater core 33, whereas the second mix door 34 b located on the upper side of the vehicle flows down to the heater core 33 and the bypass path 35. Control the amount of air
[0032]
These two mix doors 34a and 34b are rotated in conjunction with mechanical (for example, link mechanism) or electrical (for example, actuator motor and controller), and thereby the amount of air passing through the heater core 33 and the bypass path 35 are rotated. The ratio to the amount of air passing through is adjusted.
[0033]
In the air conditioning unit 30 of the present embodiment, the mix door provided between the evaporator 32 and the heater core 33 is divided into two parts, a first mix door 34a and a second mix door 34b, so one mix Compared with the case where the temperature is controlled by the door, the range required for the rotation is small. That is, the dimension in the vehicle longitudinal direction between the evaporator 32 and the heater core 33 can be set short, and as a result, the air conditioning unit 30 that is short in the vehicle longitudinal direction can be provided.
[0034]
In the air-conditioning unit 30 of the present invention, the mix doors 34a and 34b can be constituted by butterfly-shaped doors as shown in FIGS. In this case, when the cold air passage 43 is omitted as shown in FIG. 6, both the first and second mix doors 34 a and 34 b can be constituted by butterfly doors. In addition, when the cold air passage 43 is provided as shown in FIG. 7, it is desirable that only the second mix door 34b is a butterfly door. By making the mix door a butterfly-like door, the dimension in the vehicle front-rear direction is further shortened. In addition, when a butterfly door is used, even if a drag acts on one door piece due to wind, the wind acts as a tailwind on the other door piece, so the operating force required to rotate the door is small. There is also an advantage of becoming.
[0035]
The air conditioning unit 30 of the present embodiment cools the air blown from the intake unit 10 with the above-described evaporator 32 and then controls the temperature with the heater core 33 and distributes conditioned air from a desired outlet to the vehicle interior. Has a function to wind. For this purpose, an air mix chamber C is formed on the vehicle upper side of the heater core 33 of the air conditioning unit case 31, and the warm air for guiding the warm air that has passed through the heater core 33 to the air mix chamber C or the foot outlet 39. A passage 41 is formed on the back surface of the heater core 33.
[0036]
In addition to this, in the air conditioning unit of the present embodiment, the cold air passage 43 is formed below the heater core 33. When the first mix door 34a does not fully open the heater core 33, the cold air from the evaporator 32 is generated. It passes through the cold air passage 43 and is guided to the hot air passage 41. The cold air passage 43 is for suppressing an increase in temperature difference between the cold air from the vent outlet 37 and the hot air from the foot outlet 39 in the bi-level mode, and is omitted in the present invention. It is also possible.
[0037]
In the air mix chamber C, a vent outlet 37 and a defrost outlet 38 are formed.
The vent outlet 37 communicates with the vent grill provided on the front surface of the instrument panel IP in the passenger compartment through the air duct or directly, and blows conditioned air mainly toward the upper body of the occupant.
[0038]
The defrost outlet 38 communicates with the defrost grill provided on the upper surface of the instrument panel IP through an air duct or blows low-humidity air or hot air toward the inner surface of the windshield to clear the cloudiness.
[0039]
On the other hand, the foot outlet 39 is formed on the vehicle lower side of the warm air passage 41 and opens at the feet of the passengers in the passenger compartment, and mainly blows warm air toward the feet of the passengers.
[0040]
A vent door 37D, a differential door 38D, and a foot door 39D are provided in the vent outlet 37, the defrost outlet 38, and the foot outlet 39, respectively, and open and close the respective outlets.
[0041]
These doors 37D, 38D, and 39D are operated by a mode door actuator or a manual wire through a link mechanism or the like. That is, these doors operate according to the combination of opening and closing of the three doors 37D, 38D, and 39D by selecting various blowing modes such as a vent mode, a defrost mode, a bi-level mode, and a foot mode.
[0042]
For example, in the bi-level mode, the vent air outlet 37 and the foot air outlet 39 are respectively opened half way, cold air is blown out from the vent air outlet 37, and warm air is blown out from the foot air outlet 39, so-called head cold foot heat type temperature control is performed.
[0043]
In particular, in the air conditioning unit 30 of the present embodiment, the vent door 37D not only opens and closes the vent outlet 37, but also has a structure that can close the upper end of the hot air passage 41. Specifically, as shown in the figure, a rib 42 is formed at the upper end of the heater core 33 so that the tip of the vent door 37D can contact. On the vent door 37D side, in addition to the conventional vent blow outlet fully closed position, half open position, and also fully closed position, a hot air passage full closed stop position is added by a link mechanism or actuator. ing.
[0044]
Next, the operation will be described.
3 shows the full cool mode, FIG. 4 shows the temperature control / vent mode, and FIG. 5 shows the air flow in the temperature control / bi-level mode.
[0045]
First, in the full cool mode, as shown in FIG. 3, the defrost outlet 38 and the foot outlet 39 are fully closed, the vent outlet 37 is fully opened, and the hot air passage 41 is fully closed. That is, the vent door 37D is set to the maximum rotation position. The first mix door 34a fully closes the heater core 33, the second mix door 34b fully closes the heater core 33, and fully opens the bypass path 35. The cooling cycle is normally ON.
[0046]
In this way, the intake air introduced from the intake unit 10 to the inlet 40 flows toward the rear side of the vehicle while passing through the air passage surface 32a of the evaporator 32, and mainly reaches the bypass passage 35 and directly reaches the vent outlet. It flows into 37. Here, some of the cool air flowing down from the evaporator 32 passes through the cool air passage 43 and reaches the warm air passage. The hot air passage 41 is closed at the upper end by the vent door 37D and at the lower end by the foot door 39D. Therefore, when the internal pressure of the hot air passage rises, no more air flows in.
[0047]
Thus, in the full cool mode, the air is warmed on the back surface of the heater core 33 (that is, on the warm air passage 41 side), but the upper end of the warm air passage 41 is blocked by the vent door 37D, so As a result, only the cool air from the evaporator 32 flows, and as a result, the cooling capacity is secured only by modifying the vent door 37D.
[0048]
Further, since the air flow path from the inlet 40 to the vent outlet 37 is formed in a substantially straight line, the ventilation resistance is extremely small, and a large amount of cold air can be supplied to the room. Here, as shown in FIG. 6, if the second mix door 34b is configured as a butterfly-like door, the cold air passing through the second mix door 34b can be deflected to the vent outlet 37, so that the reduction of ventilation resistance is further promoted. The
[0049]
In the temperature control mode for supplying air at an intermediate temperature and in the bi-level mode (temperature control / vent mode), the defrost outlet 38 and the foot outlet 39 are fully closed as shown in FIG. 37 is fully open. At this time, the vent door 37D does not fully close the warm air passage 41. The first mix door 34a and the second mix door 34b are semi-closed.
[0050]
In this way, the intake air introduced from the intake unit 10 to the inlet 40 flows toward the rear side of the vehicle while passing through the air passage surface 32a of the evaporator 32, and the air flowing to the bypass path 35 and the heater core 33. And the air flowing into the cool air passage 43 are branched. Among these, the air (warm air) passing through the air passage surface 33a of the heater core 33 and the air passing through the cool air passage 43 rise while mixing in the hot air passage 41, and from the gap of the vent door 37D, the air mix chamber. Flows into C. And in this air mix chamber C, it mixes with the pure cold air from the bypass path 35, and after adjusting temperature to appropriate temperature, it flows into a vent blower outlet.
[0051]
As described above, in the temperature control / vent mode, the warm air passage 41 is not blocked by the vent door 37D, so that the warm air from the warm air passage 41 can be guided to the air mix chamber C. realizable. Further, as shown in the figure, the vent door 37D slightly opens the hot air passage 41, so that the internal pressure in the hot air passage 41 becomes relatively high. The hot air flow velocity is increased. In this way, by blowing out the warm air from the warm air passage 41 farther, the mixing with the cold air is improved, and uniform temperature-controlled air can be supplied into the room.
[0052]
On the other hand, in the bi-level mode (temperature control / bi-level mode) in which air at an intermediate temperature is supplied, as shown in FIG. 5, the defrost outlet 38 is fully closed, and the vent outlet 37 and The foot outlet 39 is half open. Further, the first and second mix doors 34a and 34b are each at a substantially intermediate position.
[0053]
In this way, the intake air introduced from the intake unit 10 to the inlet 40 flows toward the rear side of the vehicle while passing through the air passage surface 32a of the evaporator 32. The second mixed door 34 b branches into the air guided to the bypass path 35, the air guided to the heater core 33, and the air guided to the cool air passage 43.
[0054]
The cold air branched to the bypass path 35 collides with the warm air that has passed through the heater core 33 and has risen in the warm air passage 41 in the air mix chamber C. As a result, after mixing and reaching an appropriate temperature, the air flows into the vent outlet 37 and air having an appropriate temperature is supplied to the upper body of the passenger. Moreover, the warm air that has passed through the heater core 33 and the cold air that has passed through the cool air passage 43 are mixed in the hot air passage 41 and flow into the foot blowing duct 42 in a state in which the temperature is slightly lowered, which is higher than that of the vent blowing duct. Air is supplied from the foot outlet 39 to the passenger's feet. However, since the cold air passage 43 is provided, an extreme temperature difference is avoided.
[0055]
Thus, in the temperature control / bi-level mode, the cold air that has passed through the bypass passage 35 and the warm air that has risen through the heater core 33 collide in a substantially perpendicular direction, so that the mixing property is improved and uniform. Temperature-controlled air with a suitable temperature is supplied into the room. In addition, the presence of the cold air passage 43 can adjust the magnitude of the bi-level difference temperature, and can realize the head cold foot thermal temperature adjustment according to the environment.
[0056]
The embodiment described above is described for facilitating the understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
[0057]
【The invention's effect】
As described above, according to the present invention, mixing of warm air by the heater core can be prevented with a simple structure by the vent door, so that a reduction in cooling capacity can be prevented at low cost.
