[Industrial applications]

 The present invention relates to a structure of a front portion of an engine hood in an industrial vehicle such as a forklift, particularly an industrial vehicle equipped with an air conditioner unit.

[0002]

[Prior art]

 In recent years, it has become necessary to install air conditioning equipment on industrial vehicles such as forklifts. In this type of air conditioner-type forklift, as shown in FIG. 5, an air conditioner unit 91 is arranged beside the driver's seat 94. The air conditioner unit 91 has a housing 910, and a cooler unit (not shown), a heater unit (not shown), an air cleaner 92, etc. are housed in the housing 910.

A cap 922 is detachably attached to the front portion of the air cleaner 92. The cap 922 is attached and detached when the element 920 in the air cleaner 92 is replaced. An opening 914 is provided on the front surface of the housing 910 at a position corresponding to the cap 922. The opening 914 is for attaching and detaching the cap 922. An air cleaner cover 913 is detachably attached to the opening 914 by a clip 916. The air cleaner cover 913 is for protecting the front part of the air cleaner 92 in the housing 910.

On the other hand, an engine hood 93 is arranged on the lower surface of the driver's seat 94. The engine hood 93 is for covering the engine room 930. The engine hood 93 is attached to the frame 90 of the forklift so as to be openable and closable by a hinge (not shown). The engine room 930 is located on the side of the air cleaner 92, and the inside of the housing 910 and the engine room 930 communicate with each other. That is, the housing 910 and the engine hood 93 have a structure in which the facing side surfaces are opened. As a result, the tightening band (see FIG. 4) of the air cleaner 92 in the housing 910 can be attached and detached from the engine room 930 side.

Further, as described above, since the engine hood 93 has a structure in which the side surface is opened, a reinforcing plate (not shown) for reinforcing the engine hood 93 is provided in the engine hood 93. In FIG. 5, reference numeral 911 is an operation switch of the air conditioner unit 91, reference numeral 912 is an outlet for conditioned air, reference numeral 931 is a hook for locking the engine hood 93 to a closed state, and reference numeral 95 is a head guard. Show pillars.

[Problems to be solved]

 However, with conventional industrial vehicles, the air cleaner element replacement work was troublesome. In addition, the cost of the air cleaner protection member such as the air cleaner cover was high. This point will be described in detail with reference to FIG. The conventional engine hood 93 is separate from the air cleaner cover 913. Therefore, the inspection work in the engine room 930 and the element replacement work of the air cleaner 92 are performed separately.

When replacing the element 920 of the air cleaner 92, it is necessary to first loosen the clip 916 and remove the air cleaner cover 913 from the front surface of the housing 910. Next, it is necessary to remove the cap 922 of the air cleaner 92. This allows the element 920 in the air cleaner 92 to be taken out. As described above, conventionally, the air cleaner cover 913 had to be attached and detached, and the element replacement work of the air cleaner was troublesome. Furthermore, when a band for tightening is used, the work of removing the band must be performed after opening the engine hood 93, which makes the element replacement work even more troublesome.

Further, conventionally, it was necessary to manufacture the air cleaner cover 913 separately from the engine hood 93. Further, in order to attach / detach the air cleaner cover 913, it was necessary to produce the clip 916. Further, the air cleaner cover 913 was required to be provided with a through hole 917 for inserting the clip 916, while the housing 910 was also required to be provided with an engaging hole 918 for fitting the clip 916. Therefore, in the conventional industrial vehicle, the cost of the air cleaner protection member such as the air cleaner cover 913 is high. In view of such conventional problems, the present invention aims to provide an engine hood for an industrial vehicle that can smoothly perform element replacement work and reduce the cost of an air cleaner protection member. ..

[Means for solving the problem]

 The present invention has an air conditioner unit, an air cleaner provided in the air conditioner unit, an element replacement cap provided in the front part of the air cleaner, an engine room arranged on the side of the air cleaner, and an openable / closable cover that covers the engine room. In an industrial vehicle having a different engine hood, the engine hood is configured to integrally cover the front of the cap of the air cleaner. What is most noticeable in the present invention is that the engine hood is configured to also serve as the air cleaner protection member. That is, the engine hood is integrally formed with a part corresponding to the air cleaner protection member (hereinafter referred to as "air cleaner protection part").

The air cleaner protection portion of the engine hood is formed so as to cover the front of the cap. Further, it is desirable that the air cleaner protection portion is formed so as to be flush with the other portion (engine room protection portion) of the engine hood (see FIG. 1). This makes it possible to obtain an engine hood with excellent appearance. In addition, it is desirable to provide a reinforcing part in the air cleaner protection part (see Fig. 1). This eliminates the need for a separate reinforcing plate inside the engine hood, which is required in the past, and enables cost reduction.

[0011]

[Action and effect]

 In the present invention, the engine hood is configured to integrally cover the front of the cap of the air cleaner. In other words, the engine hood is integrally formed with the air cleaner protection part. Therefore, the cost is significantly lower than when the air cleaner protection member is manufactured separately from the engine hood as in the past. When the engine hood is closed, the engine hood integrally covers the front of the cap of the air cleaner and the engine room. Therefore, the front part of the air cleaner can be protected by the engine hood.

When the engine hood is opened, the air cleaner cap is exposed. Therefore, it is possible to replace the air cleaner element by removing the cap. Therefore, according to the present invention, it is possible to provide an engine hood for an industrial vehicle in which the element replacement work can be performed smoothly and the cost of the air cleaner protection member can be reduced.

【Example】

 An engine hood for an industrial vehicle according to an embodiment of the present invention will be described with reference to FIGS. This example is applied to the engine hood of a forklift as an industrial vehicle. As shown in FIGS. 1 and 2, the forklift of this example includes an air conditioner unit 91, an air cleaner 2 provided in the air conditioner unit 91, an element replacement cap 22 provided on the front surface of the air cleaner 2, and an air cleaner 2 side. It has an engine room 930 disposed on one side and an openable / closable engine hood 1 covering the engine room 930. The engine hood 1 is configured to integrally cover the front of the cap 22 of the air cleaner 2.

As shown in FIG. 1, the engine hood 1 includes an engine room protection part 11 for covering the engine room 930 and an air cleaner protection part 12 for covering the front of the cap 22 of the air cleaner 2. The engine room protection portion 11 and the air cleaner protection portion 12 are formed integrally and flush with each other. Further, a reinforcing portion 120 is provided on the side and the upper surface of the air cleaner protection portion 12. As shown in FIGS. 3 and 4, the air cleaner 2 is detachably attached to a main body case 21 formed in a cylindrical shape, an element 23 housed in the main body case 21, and an open end of the main body case 21. It comprises the cap 22 and a band 26 for tightening.

The body case 21 has an outlet 25. The air cleaner 2 and a duct (not shown) in the air conditioner unit 91 are connected via the outlet 25. Others are the same as in the conventional example. In FIG. 2, reference numeral 932 indicates a lock fitting that engages with the hook 931 described above, and reference numeral 96 indicates an engine, which are the same as conventional ones. 3 and 4, reference numeral 24 indicates a set screw for attaching and detaching the element, and reference numeral 27 indicates a set screw for attaching and detaching the band.

Since the engine hood of this example is configured as described above, it exhibits the following operational effects. That is, as shown in FIG. 1, the engine hood 1 is integrally formed with an air cleaner protection portion 12 for covering the front of the cap 22 of the air cleaner 2. Therefore, compared to the conventional case where the air cleaner protection member is manufactured separately from the engine hood, the man-hours are reduced and the cost can be significantly reduced.

Then, as shown in the figure, when the engine hood 1 is closed, the engine hood 1 integrally covers the front of the cap 22 of the air cleaner 2 and the engine room 930. Therefore, the engine hood 1 can simultaneously protect the engine room 930 and the front part of the air cleaner 2. The front part of the engine hood 1 is flush. Therefore, even if the air cleaner protection portion 12 is provided as described above, the appearance of the entire engine hood is not damaged.

Further, when the engine hood 1 is closed, the reinforcing portion 120 of the air cleaner protection portion 12 supports the front right end portion of the engine hood 1. Therefore, unlike the conventional case, it is not necessary to separately provide a reinforcing plate in the engine hood 1, and the cost can be reduced. On the other hand, as shown in FIG. 2, when the engagement state between the hook 931 and the lock fitting 932 is released and the engine hood 1 is opened, the engine 96 in the engine room 930 and the housing 910 of the air conditioner unit 91 are opened. Air cleaner 2 is exposed. Therefore, repair and inspection in the engine room 930 and replacement of the element 23 of the air cleaner 2 can be simultaneously performed by simply opening the engine hood 1.

When replacing the element 23 of the air cleaner 2, first, the set screw 27 is loosened and the tightening band 26 (FIG. 4) is removed from the engine room 930 side. Next, the cap 22 of the air cleaner 2 is removed forward from the opening 914 of the housing 910. After that, the set screw 24 (Fig. 4) is loosened and the element 23 is replaced. As described above, according to this example, the element replacement work can be smoothly performed. Further, the cost of the air cleaner protection member etc. can be reduced. The engine hood of this example also has excellent appearance.
