Abstract

(57) [Summary] [Purpose] To make it possible to increase the leg space for the driver in air ducts for air conditioners of construction machinery where the driver's seat is located near the center of the driver's cab in the widthwise direction of the vehicle. . [Structure] The air duct 3 is made into Y-shaped air ducts 4 and 5 that branch near the center of the driver's cab, and the parts of the part where the wind rises onto the floor 6 are integrated with the floor mounting seats 8 and 9. It is said that

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was developed for air conditioners installed in construction machinery such as wheel loaders. This relates to air ducts (air ventilation pipes) for

0002

[Conventional technology]

Figure 4 shows a side view of the main parts of a conventional air conditioner device for wheel loaders. , the top view is also shown in FIG. In the figure, a compressor driven by engine a The compressed air from b passes through air pipe c and is turned into warm air or hot air by air conditioner unit d. It becomes cold air and is distributed to each part from air mixing box e, but some of it is A pipe formed of a hose passes through an under-floor duct g that is integrated with the floor f. Hot or cold air blows out from the outlet grill i through the lower upper duct h. ing.

[Problem that the idea aims to solve]

In the conventional air duct shown in FIGS. 4 and 5 above, there is an operator seat k in the center of the driver's cab j, and when installing the under-floor duct g, the floor mount mounting seats m ₁ , m ₂ , m ₃ , m _A duct g, which is integrated with the floor f or has a separate structure, is installed in a position away from the floor f, and is connected to the air outlet grille i through the floor duct h. (not shown), there was a major problem in that the driver could not secure sufficient leg space.

0004

[Means and actions for solving the problem]

This idea was devised in view of the above, and was designed to connect the floor mounting seat of the driver's cab and the air adapter. The air duct is constructed in one piece, and the air duct is arranged in a Y-shape branch near the center of the driver's cab. By installing this, the air duct and control devices such as the accelerator pedal are separated, making it easier for the driver to The aim is to provide construction vehicles with increased leg space and improved driving and livability.

【Example】

Embodiments of this invention will be described below based on the drawings. Figure 1 is based on this idea. Figure 2 is a side view of the main parts of the air conditioner device of a wheel loader, and Figure 2 is a top view. , FIG. 3 is a 30-30 sectional view in FIG. In the diagram, air conditioner unit 1 The hot air or cold air from the air flows through the air mixing box 2 as shown by arrows 21 and 22. Flows into air duct 3, and air duct 4 branches into a Y-shape near the center of the driver's cab. , 5 and flows as shown by arrows 23 and 24, and the air shown by arrow 24 flows in Figs. 1 and 3. It is guided onto the floor 36 as shown by the arrow 25 shown in FIG. (toward the driver's head), arrow 27 (toward the driver's feet), arrow 28 (toward the front window glass) It's like it's gushing out. (The air flow shown by arrow 23 is similar, so the explanation is (omitted).

[0006] And air duct 5 (the same is true for air duct 4, so it will be omitted below) ) is the floor mounting base 8 (air duct 4 is floor mounted) as shown in Figure 3. 9), and the wind flows through the flow as shown by arrow 25 as mentioned above. A6. 11 is the frame, 12 is the rubber cushion, and the floor mounting seat 8 is It is integrated with the floor 6 and is bolted together, and 10 is a cover that is integrated with the floor 6 or bolted. The air duct 5 is also formed integrally with the floor 6 or separately. 13, 14 is a sealing member for preventing air leakage. In this way, in this embodiment, the air The duct 3 is replaced with air ducts 4 and 5 that branch into a Y-shape near the center of the driver's cab. Since the ducts 4 and 5 and the floor mounting seats 8 and 9 are integrated, the structure is simple and the driver's This increases leg space and greatly improves driving and living comfort.

[0007]

[Effect of the idea]

This idea was developed as described in detail above, and the driver's seat is located inside the driver's cab in the vehicle width direction. In the air duct for the air conditioner of construction machinery near the center, the air conditioner The duct is branched into a Y-shape near the center of the driver's cab, and the part where the wind rises above the floor is The simple structure of integrating the material with the floor mounting seat increases the leg space for the driver. This has the great effect of significantly improving driving and livability. .
