Description

  The present invention relates to a vehicle defroster device that blows conditioned air for defrosting from a passenger compartment toward a side glass.

Conventionally, as shown in Patent Document 1 below, in a vehicle defroster device that blows conditioned air toward a side glass, an air-conditioning air outlet is opened on the upper surface of the instrument panel, and the conditioned air is supplied to the side glass through the outlet. The frost and cloudiness of the side glass have been removed by spraying.
Registered Utility Model No. 2598089

  However, in the vehicle defroster device disclosed in the above-mentioned Patent Document 1, since the air outlet of the conditioned air is provided on the upper surface of the instrument panel, the glass surface of the side glass installed substantially vertically is almost Air-conditioned air is blown from the upper surface of the instrument panel extending in the horizontal direction. For this reason, air-conditioned air cannot be efficiently blown toward the side glass, and there has been a problem that it is difficult to effectively remove frost and fog on the glass surface.

  The present invention has been made in view of the above-described problems, and can efficiently blow conditioned air onto the side glass, thereby more effectively removing frost and cloudiness on the glass surface. An object of the present invention is to provide a defroster apparatus for use.

  In order to solve the above-mentioned problems, the present invention provides a vehicle defroster device that blows conditioned air from a passenger compartment toward a side glass, which is a blowout port for the conditioned air and is directed toward the front portion of the side glass. A defroster port is provided at a position where conditioned air can be blown, and the defroster port is installed on the upper surface portion of the instrument panel or a vehicle body component around the instrument panel, and rises upward by a predetermined distance when viewed from the rear of the vehicle. It is provided in the rising part (Claim 1).

  According to the present invention, a rising portion that rises a predetermined distance from the upper surface portion of the instrument panel or its surrounding vehicle body component is provided, and a rising portion that is installed in a substantially vertical direction is provided by providing a defroster port at the rising portion. Since the defroster port is opened on the rising surface of the unit and the conditioned air can be blown through the defroster port in a substantially horizontal direction, the conditioned air is efficiently blown against the glass surface of the side glass installed in a substantially vertical direction. Can do. For this reason, unlike the defroster apparatus of the said patent document 1 which ventilates conditioned air upwards through the blower outlet opened on the upper surface of an instrument panel, the frost and cloudiness of a glass surface can be removed more effectively.

  It is preferable that the rising portion is installed on the front side of the vehicle rather than the vicinity of the front end portion of the side glass.

  If it does in this way, the situation where the above-mentioned standing part prevents the side view which passed the front end part of the side glass can be avoided effectively.

  Auxiliary side glass installed between the front glass door glass, the auxiliary pillar located in front of the door glass, and the front pillar to which the side edge of the windshield is attached in front of the side glass. In this case, conditioned air may be blown from the defroster port toward the auxiliary side glass.

  As described above, when conditioned air is blown to the auxiliary side glass (for example, a triangular window) installed between the front pillar and the auxiliary pillar, it is installed in order to secure a wider side view. There is an advantage that the side field of view can be favorably maintained by effectively removing frost and cloudiness of the auxiliary side glass.

  Panel side portions that are installed between the front pillars and the auxiliary pillars and are adjacent to the inner side surface of the auxiliary side glass are provided on the left and right sides of the upper surface portion of the instrument panel or the surrounding vehicle body components. When it exists, it is preferable that the upper surface of this panel side part is comprised by the inclined surface which inclines so that it may fall below, so that the said auxiliary | assistant side glass is approached (Claim 4).

  As described above, when the upper surface of the side portion of the panel adjacent to the inner side surface of the auxiliary side glass is configured with an inclined surface that is inclined to fall downward toward the auxiliary side glass, the lower end of the exposed portion of the auxiliary side glass is more Since it can set to a low position, the side field of view through this auxiliary side glass can be expanded further downward. In addition, it is conceivable to provide the auxiliary side glass defroster port on the upper surface of the side portion of the panel having the inclined surface as described above. When a drink is spilled, the drink may easily enter from the defroster port for the auxiliary side glass. That is, when the upper surface of the side portion of the panel is formed of the inclined surface as described above, a concave portion is formed in a region surrounded by the inclined surface and the front pillar, auxiliary pillar, and auxiliary side glass. The spilled drink easily accumulates in the recess, and the drink may easily enter from the auxiliary side glass defroster port provided on the upper surface of the side portion of the panel (corresponding to the bottom surface of the recess) as described above. In contrast, according to the present invention, since the auxiliary side glass defroster port is provided at the rising portion installed on the upper surface of the instrument panel, such a problem can be prevented.

  When the front pillar to which the side end portion of the windshield is attached is provided on the front side of the side glass, the defroster port is provided at a rising portion installed on the inner side in the vehicle width direction than the front pillar. (Claim 5).

  In this way, unlike the case where the rising portion is constituted by a part of the front pillar, for example, the strength can be ensured without increasing the diameter of the front pillar, so the side glass positioned behind the front pillar. There is an advantage that the side field of view through the front part can be effectively improved.

  As described above, according to the vehicle defroster device of the present invention, conditioned air can be blown to the side glass more efficiently, so that frost and cloudiness on the glass surface can be effectively removed.

The panel main body 14 and the center cluster portion 16 are installed in a state of being lowered a predetermined distance below the panel front end portion 12 located in front thereof. Therefore, a rising portion 20 that rises upward by a predetermined distance from the upper surface of the panel main body 14 is formed at the boundary between the panel front end portion 12 and the panel main body 14 (and the center cluster portion 16). The rising portion 20 extends from the vicinity of the front end portion of the auxiliary side glass 48 substantially in parallel to the vehicle width direction, and is set so that the rising surface faces the rear side of the vehicle. However, the left and right side portions of the rising portion 20 are provided with side inclined portions 20a that extend so as to be positioned in front of the vehicle toward the outside, and the rising surfaces of the side inclined portions 20a are: It is installed so as to face the diagonally rear side on the outer side in the vehicle width direction.

  The panel body 14 has an upper surface portion 14a extending rearward from the lower end portion of the rising portion 20, and a rear surface portion 14b extending downward from the rear end portion of the upper surface portion 14a. The upper surface portion 14a is constituted by a rearwardly inclined surface whose height decreases toward the rear side of the vehicle.

  On the outer side in the vehicle width direction of the panel main body 14, a raised portion is formed so as to protrude from the upper surface portion 14 a and the rear surface portion 14 b of the panel main body 14 and to be divided into two columns along the diagonal line. 18 is installed. As shown in FIGS. 1 and 4, the raised portion 18 is raised from the upper surface portion 14 a of the panel main body 14 so as to form an arc shape in a sectional view, and the rear surface of the vehicle in which the height of the upper surface portion 14 a is lowered. It is formed so that the height of the ridge becomes higher toward the side.

  Between the front pillar 40 and the auxiliary pillar 42, there is provided a panel side portion 22 installed on the side of the panel body 14 so as to form a surface continuous with the upper surface portion 14a of the panel body 14.

  Next, air conditioning equipment provided in the passenger compartment will be described. A rear surface portion of the raised portion 18 formed in the panel body 14 of the instrument panel 10 is an air-conditioning air outlet that blows air toward an occupant (vehicle interior) for temperature adjustment in the vehicle interior. A side vent port 32 is provided that opens in a circular shape with an outer diameter slightly smaller than the rear surface portion of the raised portion 18. In addition, a center vent port 30 that is a blowout port of conditioned air for adjusting the temperature in the passenger compartment and that opens in a circular shape similar to the side vent port 32 is also provided on the rear surface of the center cluster portion 16 of the instrument panel 10. Provided (in the illustrated example, two center vent ports 30 are provided). Inside these center vent port 30 and side vent port 32, wind direction plates 31, 33 are respectively attached. By changing the installation angle of these wind direction plates 31, 33, the wind direction of the conditioned air can be adjusted. ing.

  Further, the raised portion 18 of the panel body 14 is an air outlet for air-conditioned air blown toward the front portion of the door glass 46 (mainly the portion where the side mirror 54 is visually recognized). There is provided a door glass defroster port 34 formed by cutting out the outer surface in the vehicle width direction over a predetermined range. Further, the side inclined portion 20a of the rising portion 20 formed in the instrument panel 10 is for the auxiliary side glass that is a blowout port of conditioned air blown toward the auxiliary side glass 48 and opens in a substantially rectangular shape. A defroster port 36 is provided. The conditioned air blown from the door glass defroster port 34 and the auxiliary side glass defroster port 36 plays a role of removing frost and cloudiness adhering to the glass surface by being blown onto the door glass 46 and the auxiliary side glass 48. Further, inside the door glass defroster port 34 and the auxiliary side glass defroster port 36, wind direction plates 35 and 37 for directing the wind direction of the conditioned air in a target direction are respectively attached.

  As shown in FIGS. 2 and 3, an air conditioning duct 60 serving as a passage for conditioned air (arrow A in FIG. 2) for adjusting the passenger compartment temperature blown into the passenger compartment is provided inside the instrument panel 10. A defroster duct 62 serving as a passage for defroster conditioned air blown toward the side glass 50 (arrow B in FIG. 2) is provided. The air conditioning duct 60 and the defroster duct 62 are installed below the center cluster portion 16 of the instrument panel 10 and extend from an air conditioner unit (not shown) including an evaporator, a heater core, and the like. The port 30, the side vent port 32, the door glass defroster port 34, and the auxiliary side glass defroster port 36 communicate with each other. 2 and 3, the center vent port 30 is omitted, but the center vent port 30 is connected to a duct extending from the central portion of the air conditioning duct 60 in the vehicle width direction. ing.

  The air-conditioning duct 60 has a left and right piping part 60a extending from the inner side to the outer side in the vehicle width direction, and a front and rear piping part 60b bent from the left and right piping part 60a and extending to the rear side of the vehicle. The conditioned air A for room temperature adjustment is blown toward the occupant through the side vent port 32 that opens at the most downstream of 60b.

  The defroster duct 62 includes left and right piping portions 62a extending from the inner side to the outer side in the vehicle width direction, and front and rear piping portions bent from the left and right piping portions 62a and extending to the rear side of the vehicle and leading to the door glass defroster port 34. 62b, and a branch piping portion 62c that branches from the upstream side of the upper surface portion of the front and rear piping portion 62b and extends obliquely rearward on the outer side in the vehicle width direction and communicates with the defroster port 36 for the auxiliary side glass. .

  The front and rear piping portions 62b of the defroster duct 62 are connected to the front and rear piping portions 60b of the air conditioning duct 60 in the same direction on the downstream side. However, as shown in FIG. 3 and FIG. 4, the inside of this connecting portion is partitioned by a partition wall 64, and the presence of this partition wall 64 causes conditioned air A for adjusting the cabin temperature and conditioned air for the defroster. The mixed flow with B is prevented. The front / rear piping section 62b of the defroster duct 62 is partitioned above the partition wall 64, and the defroster conditioned air B guided downstream of the front / rear piping section 62b is located above the raised section 18. The air is blown toward the door glass 46 through the door glass defroster port 34 that opens to the door.

  As described above, according to the above configuration, the instrument panel 10 is provided with the rising portion 20 that rises a predetermined distance above the upper surface portion 14a of the panel body 14, and the auxiliary side glass defroster port 36 is provided on the rising portion 20. By providing, since the auxiliary side glass defroster port 36 is opened on the rising surface of the rising part 20 installed in a substantially vertical direction, the conditioned air can be blown horizontally through the auxiliary side glass defroster port 36. Air-conditioned air can be efficiently blown against the glass surface of the auxiliary side glass 48 installed substantially vertically. For this reason, unlike the defroster apparatus of the said patent document 1 which ventilates conditioned air upwards through the blower outlet opened on the upper surface of the instrument panel 10, the frost and cloudiness of a glass surface can be removed more effectively.

  In particular, in the present embodiment, the left and right side portions of the rising portion 20 extend so as to be positioned in front of the vehicle toward the outside (the rising surface faces obliquely rearward on the outer side in the vehicle width direction). It is configured by a side inclined portion 20a, and the auxiliary side glass defroster port 36 is provided in the side inclined portion 20a, so that conditioned air is blown at a near vertical angle to the glass surface of the auxiliary side glass 48. Since it did in this way, there exists an advantage that the frost and cloudiness of a glass surface can be removed more effectively.

  Further, in the present embodiment, the rising portion 20 that rises upward from the upper surface portion 14 a of the panel main body 14 is installed in a state where the left and right side portions (side inclined portions 20 a) are positioned in the vicinity of the front end portion of the auxiliary side glass 48. Therefore, for example, unlike the case where the left and right side portions of the rising portion 20 are installed on the rear side of the vehicle rather than the vicinity of the front end portion of the auxiliary side glass 48, the rising portion 20 obstructs the side view through the auxiliary side glass 48. There is an advantage that the situation can be effectively avoided.

  Further, when the conditioned air is blown to the auxiliary side glass 48 installed between the front pillar 40 and the auxiliary pillar 42 through the auxiliary side glass defroster port 36 as in the present embodiment, There is an advantage that the side field of view can be favorably maintained by effectively removing the frost and cloudiness of the auxiliary side glass 48 installed in order to secure a wider field of view.

  Further, as in the present embodiment, when the upper surface of the panel side portion 22 adjacent to the vehicle interior side surface of the auxiliary side glass 48 is configured by an inclined surface that is inclined to fall downward as it approaches the auxiliary side glass 48, Since the lower end of the exposed portion of the side glass 48 can be set at a lower position, the side field of view through the auxiliary side glass 48 can be expanded further downward. In this case, in this embodiment, the height of the upper end portion of the auxiliary side glass defroster port 36 provided in the rising portion 20 is the highest portion of the upper surface of the panel side portion 22 (the upper surface of the panel side portion 22 Since the conditioned air is blown obliquely downward from the auxiliary side glass defroster port 36, the lower side of the auxiliary side glass 48 is difficult to reach the conditioned air. Air-conditioned air can be reliably blown.

  It is also possible to provide a defroster port for auxiliary side glass on the upper surface of the panel side portion 22. However, in the case where the auxiliary side glass defroster port is provided on the upper surface of the panel side portion 22 having the inclined surface as described above, for example, a drink held by a drink holder attached to an installation portion or the like of the side vent port 32 When a drink spills from the vehicle to the front side of the vehicle, the drink accumulates on the outer side of the upper surface of the panel side portion 22 and the drink easily enters the defroster port for the auxiliary side glass provided on the upper surface. There is a fear. That is, when the upper surface of the panel side portion 22 is formed of the inclined surface as described above, a concave portion is formed in a region surrounded by the inclined surface and the front pillar 40, the auxiliary pillar 42, and the auxiliary side glass 48. Therefore, the spilled drink easily accumulates in the recess, and the drink easily enters from the defroster port for the auxiliary side glass provided on the upper surface of the panel side portion 22 (corresponding to the bottom surface of the recess) as described above. There is a risk. In contrast, in the present embodiment, since the auxiliary side glass defroster port 36 is provided at the rising portion 20 formed in the instrument panel 10, the drink spilled from the drinks in this way from the auxiliary side glass defroster port 36. Intrusion into the defroster duct 62 can be prevented in advance.

  In the present embodiment, the auxiliary side glass defroster port 36 is provided in the rising portion 20 formed in the instrument panel 10. However, for example, the front pillar 40 has a predetermined distance upward from the upper surface of the panel side portion 22. It is also possible to provide a defroster port 36 for the auxiliary side glass at the rising portion 24 to be installed. However, in this case, the front pillar 40 needs to be thickened to ensure strength, and the range of the side view through the auxiliary side glass 48 is narrowed. The auxiliary side glass defroster port 36 is preferably provided in the rising portion 20 installed on the inner side in the vehicle width direction than the front pillar 40.

  Further, in the present embodiment, in a vehicle in which an auxiliary side glass 48 is provided in addition to the door glass 46, the door glass defroster port 34 as an outlet for air-conditioned air blown toward the front portion of the door glass 46 is instrumented. Although the auxiliary side glass defroster port 36 as an outlet of the conditioned air blown toward the auxiliary side glass 48 is provided on the raised portion 20 of the instrument panel 20 in the raised portion 18 of the panel 10, for example, together with the auxiliary pillar 42 In a vehicle in which the auxiliary side glass 48 is omitted, the conditioned air is blown toward the front portion of the door glass 46 (side glass 50) through the auxiliary side glass defroster port 36, and the door glass defroster provided on the raised portion 18 is provided. The mouth 34 may be omitted. Conversely, in a vehicle including both the door glass 46 and the auxiliary side glass 48, both the door glass defroster port 34 and the auxiliary side glass defroster port 36 may be provided in the rising portion 20.

  In the present embodiment, the panel side portion 22, which is a separate member from the instrument panel 10, is provided on the side of the panel main body 14 of the instrument panel 10 (between the front pillar 40 and the auxiliary pillar 42). The panel side portion 22 may be constituted by a member integrated with the instrument panel 10. Further, in the present embodiment, in order to expand the side field of view through the auxiliary side glass 48, the upper surface of the panel side portion 22 is configured by an inclined surface that is inclined so as to fall downward as it approaches the auxiliary side glass 48. If this is not necessary, the upper surface of the panel side portion 22 may be a flat surface.

It is a perspective view which shows the condition of the vehicle interior of the vehicle by which the vehicle defroster apparatus concerning one Embodiment of this invention is mounted. It is a figure which shows the arrangement structure of the air-conditioning duct used for the said vehicle defroster apparatus. It is a top view which similarly shows the arrangement | positioning structure of an air conditioning duct. It is sectional drawing which shows the II cross section in FIG.
