Abstract

PURPOSE:To provide possibility of using a wind shield wiper even when snow lies on it by blasting warm wind from an airconditioner into a wiper cover, and allowing wind to blow against the wind shield panel from a hole provided at the edge part. CONSTITUTION:When the external air temp. is lower than a specified temp. value, a warm wind is introduced into a passage 24e in a wiper cover 24 from an airconditioner via a conduit pipe 25, and wind is delivered to the wind shield panel (glass) 12 from a hole 24f furnished at the edge so as to melt the snow deposited on the wind shield panel 12, and thus the wiper cover 24 is secured with free motion of opening and closing. When out of service, the wiper 16 is accommodated in a recess 17, and the opening 17a is enclosed with the wiper cover 24. When the wiper is in service, an opening/closing means moves the wiper cover 24 upward to open the opening 17a of the recess 17, and the wiper 16 is actuated. Thus the wind shield wiper can be in service certainly even in the event of deposited snow.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a front window wiper storage device,
In particular, this relates to front window wiper storage devices that are designed to protect against freezing and snow accumulation. [Prior Art] As a conventional device of this type, there is, for example, the one shown in FIG. 6 (see Japanese Utility Model Application Publication No. 158555/1983). The code 1 in the figure is the engine hood. Code 2 is the front window glass, code 3 is the cowl knob panel,
This cowl lug panel 3 is formed with a recess 3a extending in the vehicle width direction, and a front window wiper 8 is housed within this recess 3a. A pillar 4 is protruded from the recess 3a, and a wiper cover 5 and a link 6, which are integral with each other, are rotatably disposed on the pillar 4. A tension spring 7 is disposed between the wiper cover 5 and the recess 3a, and the tension spring 7 causes the wiper cover 5 and the link 6 to move counterclockwise as shown by the two-dot chain line in the figure. It is strongly encouraged. When the front window wiper 8 is not in use, the tip 6a of the link 6 is pressed by the wiper blade 9, and the wiper cover 5 is kept in a substantially horizontal state against the biasing force of the tension spring 7. 8 is stored covered with wiper cover 5. On the other hand, in order to use the front window wiper 8,
When the wiper switch is turned on, the wiper blade 9 is rotated and separated from the tip 6a of the link 6, so the wiper cover 5 is rotated twice as shown by the two-dot chain line in the figure due to the biasing force of the tension spring 7. The front window glass 2 is then opened and closed, and the front window glass 2 is wiped. Also, if you turn off the wiper switch while in use, 1
The tip 6a of the link 6 is pressed by the wiper blade 9 and moved clockwise against the biasing force of the tension spring 7, and is closed by the wiper cover 5. [Problem M to be solved by the invention] However, in such a conventional device, if there is snow or the like on the wiper cover 5, the wiper cover 5 cannot be opened or closed unless the snow is removed. There are cases. In particular, if you notice this while the vehicle is running, you must stop the vehicle and remove the lightning from the wiper cover 5, which is troublesome. [Means for Solving the Problems] The present invention has been made by focusing on the above-mentioned conventional problems, and includes a storage recess for storing a front window wiper on the lower edge side of the front window panel. A wiper cover is provided at the opening of the storage recess so as to be openable and closable via an opening/closing means, and when the front window wiper is not in use, the opening is closed by the wiper cover. In the automobile front window wiper storage device that is closed and opened when in use, the wiper cover is formed in a hollow shape, and an expandable communication pipe extended from the empty iJR device is connected to the wiper cover. A flow path for circulating hot air from the air conditioner is formed in the wiper power par, and an air outlet for blowing the warm air from the flow path to the front window panel is connected to the front of the wiper power par. It is characterized by an automobile front window wiper storage device formed on the edge of the window panel. [Function] According to such a means, when the outside temperature is lower than a predetermined temperature, hot air is introduced into the wiper cover from the air conditioner through the communication pipe, and the air is blown through the flow path inside the wiper cover. Warm air is blown from the mouth to the front window panel. This warm air melts snow on the front window panel, ensuring the opening and closing of the wiper cover. When the wiper is not in use, the front window wiper is stored in the storage recess, and the opening of this storage recess is closed with the wiper cover. When using the wiper, the wiper cover is moved by the opening/closing means to open the opening of the storage recess. When the wiper cover is opened or closed, the communication pipe expands and contracts in accordance with the movement of the wiper cover. [Examples] The present invention will be explained below based on examples. 1 to 5 are diagrams showing one embodiment of the present invention. First, to explain the configuration, reference numeral 11 in the figure is an engine hood. The reference numeral 12 is a front window glass, and the reference numeral l3 is a cowl box. The cowl box 13 is formed into an oval shape by a cowl top panel 14 and a dash upper panel l5. This cowl top panel 14

7 is formed along the vehicle width direction. Note that the reference numeral lea in FIG. 1 is a wiper blade of the front window wiper 16. A wiper cover 24 that opens and closes the opening 17a of the storage recess 17 is moved by an opening/closing device 18. This opening/closing device 18 is shown in FIGS.
It is configured as shown in the figure. That is, first, the fourth
As shown in the figure, the motor 19 is attached to the cowl lug panel 14.
A guide plate 20 extending in the vertical direction is also placed. As shown in FIG. 3, this guide plate 20 is formed with a vertical slit 20a extending in the vertical direction and an oblique slit 2ob extending diagonally downward in front from the upper end of the vertical slit 20a. ．． A pulley 21 is movably disposed in the slits 20a and 20b, and a shaft 22 is inserted through the pulley 21, as shown in FIG. on the other hand,
For the rotation of the motor 19 @ 1 9 a, a lever 23
The base end 23a of the lever 23 is fixed, and one end #22a of the @22 is loosely inserted into a long hole 23b formed in the lever 23. A wiper cover 24 is supported by this shaft 22. Specifically, this wiper power par 24 has a box shape, and a cover guide 24c is provided to protrude downward from a bottom surface portion 24b.
It is fixed at b. Now this wiper cover 24
is the solid line in Figure 3. One-dot chain line. It is movable as shown by the two-dot chain line. Further, inside the wiper cover 24, as shown in FIG. 2, a plurality of partitions 24a extending in the vehicle width direction are formed at appropriate intervals. A flow path 24e is now formed within the wiper force par 24,
An air outlet 24f for blowing warm air to the front window glass l2 is formed at the rear end of the vehicle (the end edge on the front window glass 12 side) of the wiper cover 24 over the entire length in the vehicle width direction. As shown in FIG. 1, the bottom surface 24b of the wiper cover 24 has a cylindrical portion 2 projecting downward at a position in front of the partition portion 24a.
4d is formed, and one end 25a of a communication pipe 25 extending from an empty TX device III 26 (details will be described later) disposed inside the instrument is connected to this cylindrical portion 24d. The communication pipe 25 has a bellows shape and is expandable and retractable, and is inserted through the opening 14a of the cowl knob panel 14 and the opening 15a of the dash upper panel 15. The other end (not shown) of this communication pipe 25 is connected to an air conditioner 26 as shown in No. 4rIIJ. This air conditioner 26 has an outside air introduction port 27a for introducing outside air and an inside air introduction port 27b for introducing inside air at one end of the air conditioning passage 27. In this air conditioning passage 27, blower 7s are arranged sequentially from the upstream side.
28. An evaporator 29 and a heater unit 30 are provided, and a foot opening 27 is provided at the other end of the air conditioning passage 27.
C. Ventilator opening 27d, defroster opening 27
e is formed, and a connecting cylindrical portion 27f to which the other end of the communication pipe 25 is connected is also formed. A heater unit 32 is disposed within the connecting tube portion 27f, and a door 31 for opening and closing the connecting tube portion 27f is also provided. This door 731 is set to open when the outside temperature falls below a predetermined temperature. Next, the operation of the automobile front window wiper storage device constructed as described above will be explained. When the wiper is not in use, the front window wiper 16 is stored in the storage recess 17, and the opening 17a of the storage recess 17 is closed with a wiper cover 24. On the other hand, when using the front window wiper 16, when the wiper switch (not shown) is turned on, the motor 19 is activated and the lever 23 is rotated as shown in the solid line, one-dot chain line, and two-dot chain line in the figure w43. Due to this rotation, the pulley 2l rises along the vertical slit 20a of the guide plate 20, the wiper cover 24 rises as shown by the dashed line in the figure, and then the pulley 21 moves forward through the diagonal slit 20b. The wiper cover 24 moves diagonally downward to the position indicated by the two-dot chain line in the figure, and then stops. Then, by driving a wiper motor (not shown), the wiper blade lea moves along the front window glass 12.
Two aspects will be wiped out. When the outside temperature is lower than a predetermined temperature in such a state where the front window wiper 16 is used or not, the door 3l is closed and the air introduced by the drive of the blower 728 passes through the heater unit 30.32. This causes warm air to flow. This hot air is then introduced into the wiper cover 24 via the communication pipe 25. Then, as shown in FIG.
4a, the air circulates throughout the vehicle width direction, flows rearward from between the partitions 24a, and is blown to the entire front window glass 12 from the entire air outlet 24f. This will melt the snow on the front window glass 12. As a result, the wiper cover 24 does not become unable to move, and the front window wiper 16 can be operated reliably. Further, unlike the conventional case, this front window wiper storage device does not use the wiper blade lea to open and close the wiper cover 24, so no external force is applied to the wiper blade lea, and the wiper blade 16a It does not cause deterioration etc. Furthermore, when the front window wiper 16 is in use, the wiper cover 24 is stopped in a substantially horizontal state as shown by the two-dot chain line in FIG. Compared to the conventional model, the air resistance during driving is reduced. [Effects of the Invention] As explained above, according to the present invention, the wiper cover is formed into a hollow shape, and the extensible communication pipe extended from the air conditioner is connected to the wiper cover. A flow path for circulating hot air from the air conditioner is formed in the wiper cover, and an air outlet for blowing the warm air from the flow path to the front window panel is located at the end of the wiper cover on the front window panel side. By forming it on the edge, warm air can be blown from the windshield of the wiper cover to the windshield.
Since it can melt accumulated snow, etc., it is possible to ensure the movable state of the wiper cover, which has the practical effect of maintaining the use of the front window wiper.
