Abstract

PROBLEM TO BE SOLVED: To provide a blower for a vehicle which can suppress a variation of an air volume from each blowout port, in the blower having two or more blowout ports which are arranged asymmetrically with respect to a rotating shaft of a motor, and an air conditioner for the vehicle.SOLUTION: A first face blowout port 21 is located at an upstream side of a rotating direction R of a centrifugal multi-blade fan 12a with respect to a second blowout port 22. Accordingly, the first face blowout port 21 becomes larger in an air amount which is blown out of the centrifugal multi-blade fan 12a than that of the second face blowout port 22. However, the first face blowout port 21 is located at a side at which a suction passage 11a is extended when viewing a blowing case 12c in a rotating axial direction. Therefore, air passing through the suction passage 11a easily flows into the second face blowout port 22 more than the first face blowout port 21.

Description

  The present invention relates to a vehicle blower and a vehicle air conditioner including two or more air outlets provided non-axisymmetrically with respect to a rotation shaft of a motor.

  The vehicular air conditioner described in Patent Document 1 employs a backward-facing fan in which the blades of the centrifugal fan face backward with respect to the rotation direction. As a result, the blowing pressure is increased as compared with a sirocco fan (forward-facing fan), for example, when blowing air from two outlets simultaneously.

  In the air conditioning unit described in Patent Document 2, a blower is provided on the downstream side of the heat exchanger for cooling and heating. This reduces the size of the air conditioning unit.

  In the vehicle air conditioner described in Patent Document 1, it is difficult to dispose the mounted upper outlet on the axis. For this reason, there is a problem that the air volume ratio varies when the air outlet is arranged on a non-axis target.

  In the air conditioning unit described in Patent Document 2, when air is blown from a plurality of air outlets, there is a problem that the air flow rate varies due to the influence of the fan rotation.

  Accordingly, the present invention has been made in view of the above-described problems, and in a blower having two or more air outlets provided non-axisymmetrically with respect to the rotation shaft of the motor, the air volume from each air outlet is reduced. It is an object of the present invention to provide a vehicle blower and a vehicle air conditioner that can suppress variations.

  The present invention employs the following technical means in order to achieve the aforementioned object.

  The present invention is a vehicle blower (12) for blowing air into a vehicle interior, which is rotationally driven by a motor (12b), sucks air in the direction of the rotation axis of the motor, blows out air in the radial direction, and blows it into the vehicle interior. A blower fan (12a) and a blower case (12c) in which the blower fan is housed, and the blower case includes at least two blowout ports (21, 22) through which air blown in a radial direction passes, A suction port (20) through which air sucked in the rotation axis direction passes is formed, and the air sucked into the blower case by the blower fan passes through the suction port (11a) extending in the radial direction and then passes through the suction port. The two outlets have a non-axisymmetric positional relationship with respect to the rotation axis when viewed in the direction of the rotation axis, and the first outlet (21) of the two outlets blows air more than the second outlet (22). fan Positioned upstream of the rotational direction, the first outlet watches blower case in the rotation axis direction, a vehicle blower, characterized in that located on the side suction path extends.

  According to such this invention, a 1st blower outlet is located in the upstream of the rotation direction of a ventilation fan rather than a 2nd blower outlet. Therefore, the amount of air blown from the blower fan is greater in the first air outlet than in the second air outlet. However, the 1st blower outlet is located in the side where a suction course extends, seeing a ventilation case in the direction of a rotation axis. Therefore, the air that has passed through the suction path flows more easily into the second air outlet than the first air outlet. This is because the first blower outlet is located on the side where the suction path extends, so that the air passing through the suction path and the suction port changes direction and reaches the first blower outlet, so that the passage resistance is large. In this way, the magnitude of the air flow rate due to being located on the upstream side in the rotational direction and the magnitude of the air flow rate due to being located on the suction path side cancel each other. Therefore, it is possible to suppress variations in the air volume from the first air outlet and the second air outlet that are provided non-axisymmetrically with respect to the rotation shaft of the motor.

  In addition, the code | symbol in the bracket | parenthesis of each above-mentioned means is an example which shows a corresponding relationship with the specific means as described in embodiment mentioned later.

  Hereinafter, a plurality of embodiments for carrying out the present invention will be described with reference to the drawings. In some embodiments, portions corresponding to the matters described in the preceding embodiments may be given the same reference numerals, or one letter may be added to the preceding reference numerals, and overlapping descriptions may be omitted. In addition, when a part of the configuration is described in each embodiment, the other parts of the configuration are the same as those of the embodiment described in advance. In addition to the combination of parts specifically described in each embodiment, the embodiments may be partially combined as long as the combination does not hinder the combination.

(First embodiment)
1st Embodiment of this invention is described using FIG. 1 and FIG. The vehicle air conditioner 10 is an apparatus that supplies air conditioned from the air outlet toward the vehicle interior. The vehicle air conditioner 10 includes an air-conditioning case 11 as an outer shell, and roughly includes a blower 12 and an air-conditioner 13. The air conditioning case 11 is disposed on the back side of an instrument panel (not shown) in front of the vehicle interior. The air conditioning case 11 has a function as a passage member that forms a suction path 11a through which air flows inward.

  The air conditioning case 11 includes an air suction path 11a inside, and an outside air introduction portion 14 and an inside air introduction portion 15 which are air introduction portions are formed on one side. Also, an inside / outside air switching door 16 is provided on one side of the air conditioning case 11. The inside air / outside air introduction unit 15 and the outside air introduction unit 14 are switched by the inside / outside air switching door 16 so that the opening and closing thereof can be switched or the degree of opening can be adjusted in accordance with the air intake mode. That is, the inside / outside air switching door 16 can be taken into the air conditioning case 11 from at least one of the outside air and the inside air by adjusting the angle of the door body with an actuator such as a servo motor. . The inside / outside air switching door 16 can be controlled to switch between the inside air circulation mode, the outside air introduction mode, and an intermediate mode (a mode having both inside air circulation and outside air introduction).

  The air blower 12 is disposed on the other side of the suction path 11a. As shown in FIG. 1, the suction path 11 a extends from the air introduction parts 14 and 15 to the blower part 12. The air conditioning case 11 includes a plurality of case members, and is a resin molded product such as polypropylene, for example. The plurality of case members are integrally coupled by fastening means such as metal springs and screws to form the air conditioning case 11.

  The blower unit 12 is a vehicle blower for blowing air inside or outside the vehicle compartment to the air conditioning unit 13. The blower outlet of the ventilation part 12 is connected with the channel | path which reaches a vehicle interior. The blower unit 12 includes a centrifugal multiblade fan 12a as a blower fan, for example, a sirocco fan and a motor 12b for driving the fan. The centrifugal multiblade fan 12a is surrounded by a blower case 12c. The centrifugal multiblade fan 12a is rotationally driven by a motor 12b, sucks air in the direction of the rotation axis of the motor 12b (vertical direction in FIG. 1), blows out air in the radial direction, and blows it into the vehicle interior.

  The blower case 12c accommodates the centrifugal multiblade fan 12a, and is formed with an air outlet that blows out from the centrifugal multiblade fan 12a. The blower case 12c is formed with two outlets 21 and 22 through which air blown in the radial direction passes and an inlet 20 through which air sucked in the rotation axis direction passes.

  The air-conditioning unit 13 includes an air-conditioning case that includes a filter 31 and an evaporator 32 provided across the entire suction path 11a, a heater core 33 that heats the air that has passed through the filter 31 and the evaporator 32, and an air mix door 34. 11 inside.

  The filter 31 is located upstream of the evaporator 32 and collects dust and the like in the passing air. The evaporator 32 and the heater core 33 are heat exchangers that are arranged upstream of the centrifugal multiblade fan 12a in the air conditioning case 11 and adjust the temperature of the passing air. The evaporator 32 is, for example, a cooling heat exchanger that is positioned on the vehicle front side of the air-conditioning case 11 and that evaporates the low-temperature and low-pressure refrigerant decompressed by the expansion valve in the refrigeration cycle by receiving air from the air blowing unit 12. . And the ventilation air which passes the circumference | surroundings of the tube through which a refrigerant | coolant flows is cooled, and cold wind is supplied to a downstream cold wind path.

  The heater core 33 is a heat exchanger for heating that is located in the lower part on the vehicle rear side of the evaporator 32, heat-exchanges with the blown air using high-temperature cooling water of the traveling engine as a heat source, and heats the air flowing around. The heater core 33 is disposed so as to partially block the passage on the downstream side in the air flow direction with respect to the evaporator 32.

  The air mix door 34 is located on the vehicle rear side with respect to the evaporator 32. The air mix door 34 adjusts the temperature of the conditioned air by adjusting the ratio of the amount of warm air passing through the heater core 33 and the amount of cool air not passing through the heater core 33 according to the opening position. When the air mix door 34 is at the position indicated by the solid line in FIG. 1, it is during maximum cooling, and the warm air passage is closed to completely block the flow of air to the heater core 33 and provide cooling air to the vehicle interior.

  Next, the blower case 12c will be further described. The two air outlets 21 and 22 formed in the blower case 12 c are a first face air outlet 21 and a second face air outlet 22. The first face outlet 21 is an opening through which air-conditioned air blown toward the upper body of the passenger seated in the driver's seat in the passenger compartment passes. The second face air outlet 22 is an opening through which conditioned air blown out toward the upper body of the passenger seated in the passenger seat in the passenger compartment.

  Further, a first face door 23 and a second face door 24 for opening and closing the first face air outlet 21 and the second face air outlet 22 are provided in the blower case 12c. The first face door 23 and the second face door 24 are one-side supported plate-like doors having a rotating shaft and a flat door plate.

  The operations of the blower 12, the air mix door 34, the first face door 23, and the second face door 24 are controlled by a control device (not shown). In such a vehicle air conditioner 10, when the centrifugal multiblade fan 12 a of the blower unit 12 is driven by the motor 12 b, air is introduced from the air introduction units 14 and 15 into the air conditioning case 11. The introduced air passes through the filter 31 and the evaporator 32, and then cool air and warm air are mixed by the opening degree of the air mix door 34. And the mixed air is guide | induced into the ventilation case 12c from the suction inlet 20 of the ventilation part 12, and is ventilated from the 1st face blower outlet 21 and the 2nd face blower outlet 22 to a passenger | crew.

  Next, the positional relationship between the first face air outlet 21 and the second face air outlet 22 will be described. As shown in FIG. 2, the two outlets 21 and 22 are in a non-axisymmetric positional relationship with respect to the rotation axis when viewed in the rotation axis direction of the motor 12 b. The first face outlet 21 is located upstream of the second face outlet 22 in the rotational direction R of the centrifugal multiblade fan 12a. Positioning upstream of the rotational direction R means upstream of the rotational direction R in the positional relationship between the air outlets adjacent to the rotational direction R on the side where the distance in the circumferential direction is small. As shown in FIG. 2, in the present embodiment, the air outlet located on the left side of FIG. The distance from the second face outlet 22 to the first face outlet 21 is smaller in the direction opposite to the rotational direction R than the distance in the rotational direction R of the centrifugal multiblade fan 12a. Therefore, the blower outlet located on the upstream side in the rotation direction R is the blower outlet located on the left side of FIG.

  The suction path 11a of the air conditioning case 11 is formed so as to extend in a direction substantially perpendicular to the rotation axis direction. As shown in FIG. 2, the 1st face blower outlet 21 is located in the side where the suction path 11a extends, seeing the ventilation case 12c in the rotating shaft direction. Therefore, the air that has passed through the suction path 11 a needs to bend the flow direction of the air more than the route that reaches the second face outlet 22 in order to reach the first face outlet 21. In other words, the air that has passed through the suction path 11 a easily flows into the second face outlet 22.

  As described above, in the vehicle air conditioner 10 of the present embodiment, the first face air outlet (first air outlet) 21 is more than the second face air outlet (second air outlet) 22 of the centrifugal multiblade fan 12a. Located upstream of the rotational direction R. Therefore, the amount of air blown from the centrifugal multiblade fan 12a is greater in the first face air outlet 21 than in the second face air outlet 22. However, the 1st face blower outlet 21 is located in the side where the suction path 11a extends, seeing the ventilation case 12c in the rotating shaft direction. Therefore, the air that has passed through the suction path 11 a flows more easily into the second face air outlet 22 than to the first face air outlet 21. Since the first face outlet 21 is located on the side where the suction path 11a extends, the air passing through the suction path 11a and the suction port 20 changes direction and reaches the first face outlet 21, so the passage resistance is large. is there. In this way, the magnitude of the blown air volume due to being located on the upstream side in the rotation direction R and the magnitude of the blown air quantity due to being located on the suction path 11a side are offset. Therefore, it is possible to suppress variation in the air volume from the first face air outlet 21 and the second face air outlet 22 provided non-axisymmetrically with respect to the rotation axis of the motor 12b. Therefore, even if the two air outlets 21 and 22 are not arranged symmetrically, variation in the amount of air blown from the air outlets 21 and 22 can be suppressed.

  In other words, in the case of sucking air from the suction path 11a substantially perpendicular to the rotation axis of the motor 12b, air flows to the first face outlet 21 provided on the upstream side in the rotation direction R as compared to the case of sucking from the rotation axis direction. Many are supplied. However, in contrast to the case where the suction path 11a is formed in parallel with the rotation axis of the motor 12b, when the air is sucked in from the suction path 11a side, more air is supplied to the second face outlet 22 provided on the downstream side in the rotation direction R. A lot of wind is supplied. Therefore, there is an effect of correcting the unbalance of the air volumes of the first face air outlet 21 and the second face air outlet 22.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. This embodiment is characterized in that the positions of the air outlets are different.

  As shown in FIG. 3, the outer shape of the blower case 12c is square when viewed in the direction of the rotation axis. The two outlets are formed on different surfaces. The first face outlet 21 is formed on the surface 40 closest to the suction path 11a. The most suction path 11a side means the most air introduction parts 14 and 15 side of the suction path 11a. The 2nd face blower outlet 22 is formed in the surface 41 adjacent to the surface 40 in which the 1st face blower outlet 21 is formed in the rotation direction R downstream.

  As a result, since the first face outlet 21 is upstream in the rotational direction R, there is a large amount of air from the centrifugal multiblade fan 12a, but the air that has passed through the suction path 11a is less likely to flow. On the other hand, since the second face outlet 22 is on the downstream side in the rotational direction R, the amount of air from the centrifugal multiblade fan 12a is small, but the air that has passed through the suction path 11a is likely to flow. As a result, similar to the first embodiment described above, there is an effect of correcting the unbalance of the air volumes of the first face air outlet 21 and the second face air outlet 22.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG. This embodiment is characterized in that the positions of the air outlets are different.

  As shown in FIG. 4, the outer shape of the blower case 12c is square when viewed in the direction of the rotation axis. The two outlets are formed on different surfaces. The 2nd face blower outlet 22 is formed in the surface 42 farthest from the suction path 11a. The farthest from the suction path 11a side means the farthest from the air introduction portions 14 and 15 of the suction path 11a. The 1st face blower outlet 21 is formed in the surface 41 adjacent to the surface 42 in which the 2nd face blower outlet 22 is formed in the rotation direction R upstream.

  As a result, since the first face outlet 21 is upstream in the rotational direction R, there is a large amount of air from the centrifugal multiblade fan 12a, but the air that has passed through the suction path 11a is less likely to flow. On the other hand, since the second face outlet 22 is on the downstream side in the rotational direction R, the amount of air from the centrifugal multiblade fan 12a is small, but the air that has passed through the suction path 11a is likely to flow. As a result, similar to the first embodiment described above, there is an effect of correcting the unbalance of the air volumes of the first face air outlet 21 and the second face air outlet 22.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG. This embodiment is characterized in that the positions of the air outlets are different.

  As shown in FIG. 5, the outer shape of the blower case 12c is square when viewed in the direction of the rotation axis. The two outlets are formed on different surfaces. The 1st face blower outlet 21 is formed in the surface 40 nearest to the suction path 11a. The 2nd face blower outlet 22 is formed in the surface 42 farthest from the suction path 11a. Therefore, each blower outlet is each formed in the surface which opposes.

  As a result, since the first face outlet 21 is upstream in the rotational direction R, there is a large amount of air from the centrifugal multiblade fan 12a, but the air that has passed through the suction path 11a is less likely to flow. On the other hand, since the second face outlet 22 is on the downstream side in the rotational direction R, the amount of air from the centrifugal multiblade fan 12a is small, but the air that has passed through the suction path 11a is likely to flow. As a result, similar to the first embodiment described above, there is an effect of correcting the unbalance of the air volumes of the first face air outlet 21 and the second face air outlet 22.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described with reference to FIGS. This embodiment is characterized in that the position of each outlet and the number of outlets are different.

  As shown in FIG. 6, the outer shape of the blower case 12c is square when viewed in the rotation axis direction. The three outlets are formed on different surfaces. The 1st face blower outlet 21 is formed in the surface 40 nearest to the suction path 11a. The 3rd face blower outlet 25 is formed in the surface 42 farthest from the suction path 11a. The 2nd face blower outlet 22 is formed in the surface 41 adjacent to the surface 40 in which the 1st face blower outlet 21 is formed in the rotation direction R downstream.

  As a result, since the first face outlet 21 is upstream in the rotational direction R, the amount of air from the centrifugal multiblade fan 12a is the largest, but the air that has passed through the suction path 11a is the least likely to flow. On the other hand, since the second face air outlet 22 is on the downstream side in the rotation direction R, the air volume from the centrifugal multiblade fan 12a is smaller than that of the first face air outlet 21, but larger than that of the third face air outlet 25. In addition, the air that has passed through the suction path 11 a is easier to flow than the first face air outlet 21, but is less likely to flow than the third face air outlet 25. Moreover, since the 3rd face blower outlet 25 is the downstream of the rotation direction R, the air volume from the centrifugal multiblade fan 12a is the least, but the air which passed the suction path 11a side flows in most easily. As a result, similar to the first embodiment described above, there is an effect of correcting the unbalance of the air volumes of the first face outlet 21, the second face outlet 22, and the third face outlet 25.

  Moreover, as shown in FIG. 7, you may form four blower outlets in a respectively different surface. Even if it is the structure which has such a 4th 4th face blower outlet 26, the effect | action and effect similar to the structure of three blower outlets can be achieved.

(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described with reference to FIG. The present embodiment is characterized in that the shape of the blower case 12c and the configuration of each face door are different.

  As shown in FIG. 8, the outer shape of the blower case 12c is circular when viewed in the rotation axis direction. Each face door is realized by a rotary door that moves in an arc along the inner wall of the blower case 12c. Even with such a configuration, as in the first embodiment described above, there is an effect of correcting the unbalance of the air volumes of the first face air outlet 21 and the second face air outlet 22.

(Seventh embodiment)
Next, a seventh embodiment of the present invention will be described with reference to FIGS. FIG. 9 shows the position of each door when the blowing mode is the face mode. FIG. 10 shows the case of the foot mode, and FIG. 11 is characterized in that the shape of the blower case 12c and the configuration of each face door are different in this embodiment showing the case of the differential mode.

  As shown in FIG. 9, the outer shape of the blower case 12c is circular when viewed in the rotation axis direction. And five outlets are provided. A first foot outlet 51, a second foot outlet 52, and a differential outlet 53 are formed further than the blower 128 shown in FIG. A rotary door is provided to open and close the respective outlets. The rotary doors are a first foot door 61, a second foot door 62, and a differential door 63. The first face air outlet 21 and the second face air outlet 22 extend in the vertical direction of FIG. 9 and are in a positional relationship with respect to the axis that passes through the rotation center. Moreover, the 1st foot blower outlet 51 and the 2nd foot blower outlet 52 have the positional relationship of an axial object with respect to the axis | shaft extended in the up-down direction of FIG. 9, and passing a rotation center.

  In the face mode shown in FIG. 9, the first face outlet 21 and the second face outlet 22 are opened by the first face door 23 and the second face door 24, and the other outlets are closed. To be controlled. Since the positional relationship between the first face air outlet 21 and the second face air outlet 22 is the same as that in the above-described eighth embodiment, the effect of correcting the imbalance in the air volume between the first face air outlet 21 and the second face air outlet 22 is achieved. There is.

  In the foot mode shown in FIG. 10, the first foot outlet 51 and the second foot outlet 52 are opened by the first foot door 61 and the second foot door 62, and the other outlets are closed. To be controlled. The positional relationship between the first foot outlet 51 and the second foot outlet 52 is similar to the positional relationship between the first face outlet 21 and the second face outlet 22 of the eighth embodiment described above, although the adjacent distance is far. There is an effect of correcting the unbalance of the air volumes of the first foot outlet 51 and the second foot outlet 52.

  In the differential mode shown in FIG. 11, the differential outlet 53 is opened by the differential door 63, and the other outlets are controlled to be closed. Since only one differential outlet 53 is open, the set air volume can be supplied from the differential outlet 53.

  Thus, even when the blowing mode is switched by opening and closing each door, the two air outlets having the same positional relationship as in the first embodiment described above are opened, so that variation in air volume can be reduced.
