Abstract

PURPOSE:To easily attach and detach an evaporator without detaching a lower case by placing the front end of an evaporator on a weir provided on the front end of a lower case to be inclined, and then drawing out the evaporator in a horizontal state through an opening provided on an upper case. CONSTITUTION:An evaporator 1 is placed on a lower case 2, and stored in an upper case 3. In this case, a weir 2a projected forward and bent upward is provided on the front end of the lower case 2. On the other hand, an opening 4 is provided on the front end of the upper case 3, and the opening 4 is closed by a cover 5. The cover 5 is removably provided on the upper case 3, and a flange 5a formed by bending the lower end portion of the cover forward is placed on the weir 2a. Accordingly, after the front portion of the lower surface 1a is placed on the weir 2a to incline the evaporator 1, the evaporator 1 is drawn forward in the horizontal state, so that as there are enough clearances A, B above and below the opening 4, it is not necessary to detach the lower case 2 in order to take out the evaporator 1 from the upper case 3.

Description

Detailed Description of the Invention [Industrial Field of Application] This invention is an automotive air conditioner with a vertical layout in which a blower, a heater, and an evaporator are integrated. is concerned with improving one's sexuality).

[Prior Art] As shown in FIG. 4, if the evaporator 11 is pulled out straight from its housing case 12 in the direction of the arrow, it is disadvantageous against water leakage. Therefore, it is not a good idea to provide parting lines in areas of the housing case where water will adhere. When a conventional evaporator is a separate horizontally mounted evaporator, the evaporator is placed separately from the blower, cooler unit, heater, etc., so a storage case 22 is installed in the vertical center of the evaporator as shown in Figure 5. If the evaporator can be divided by the running line 23, replacing the evaporator and retrofitting the cooler will not be particularly difficult.

However, if the evaporator is installed vertically and is an integrated unit that includes a blower center and blower offset, and the parting line is provided at the top of the housing case, the lower case must also be removed in order to install and remove the evaporator. For this reason, currently the unit is removed from the vehicle and the evaporator is removed and installed, but retrofitting the cooler is nearly impossible. In other words, the serviceability of the evaporator is very poor.

[Problems to be Solved by the Invention] An object of the present invention is to provide an air conditioner for an automobile having an excellent serviceability in a vertically installed integrated unit type evaporator.

[i! [Technical Means for Solving the Problems] In order to solve the above problems, the present invention provides an integrated automobile air conditioner in a vertical layout, which includes a lower case that supports the lower surface of the evaporator constituting the Air II device. A weir is provided at the front end of the evaporator, and an opening is provided at the front end of the upper case that accommodates the evaporator to enable the evaporator to climb over the weir and be installed and removed into the upper and lower cases, and the upper case further opens and closes this opening. It has a structure with a removable cover.

[Function] The weir is provided at the front end of the lower case, which is advantageous in preventing water inside the unit from leaking into the passenger compartment.

In addition, the opening provided in the upper case & S is set to a shape and size that does not hinder the evaporator from climbing over the weir and being able to be installed in and removed from the upper and lower cases, making it easy to install and remove the evaporator. Make it.

[Example] The present invention will be described below based on FIGS. 1 to 3 showing examples. The evaporator 1 is placed on a lower case 2 and housed in an upper case 3. The parting lines of the upper and lower cases 3.2 are located at the bottom of the entire case.

A weir 2a is provided at the front end of the lower case 2, projecting forward from the front end of the evaporator 1 and bent upward.

An opening 4 is provided at the front end of the upper case 3.
is closed by a cover 5, and the cover 5 can be attached to and detached from the upper case 3 using screws (not shown).

The lower end of the cover 5 is bent forward to form seven flange 5a, which is placed on the dam 2a of the lower case 2.

To take out the evaporator 1 from the upper case 3, lift the front part of the evaporator 1 as shown in Fig.
Place the front part of the evaporator 1 on the weir 2a to tilt the evaporator 1, then horizontally set the evaporator 1 to the front (
Pull it out in the direction of arrow C). Above and below the opening 4 at the front end of the upper case 3, insert the evaporator 1 into the upper case 3 using the above operation.
Sufficient rear balance A, B to pull out from
have. Therefore, when taking out the evaporator from the upper case 3, there is no need to remove the lower case.

When installing the evaporator 1 in the upper and lower cases 3.2, attach the evaporator 1 to the lower case 2 as shown in Figure 3.
With the evaporator 1 placed on the weir 2a, the evaporator 1 is pushed into the upper and lower cases 3.2 through the opening 4, and placed on the lower case 2. After that, the cover 5 is attached to the upper case 3. At this time, the flange 5a of the cover 5 is placed on the weir 2a of the lower case 2. 6 is 7 lunge 5a1 weir 2a1
This is a sealing material filled between the lower ends of the evaporator 1.

In the above embodiment, the shape and size of the opening 4, and the heights of clearances A, B, and 12a between the evaporator 1 and the upper and lower portions of the opening 4 when the evaporator 1 is removed are determined by each component of the air conditioner in the actual vehicle. The higher the height of the weir 2a is, the more effective it is against water leakage, so it is better to make it as large as possible from the shape and size of the opening 4 and the relationship with the clearances A and B.

Furthermore, in the above embodiment, the floor surface of the lower case 2, that is, the surface on which the evaporator 1 is placed, is made flat, but if a plurality of parallel ribs are provided at intervals in the front and rear direction on the floor surface, slipping occurs when the evaporator is attached or detached. The attachment and detachment work can be done with little force.

[Effects] Since the present invention has the above configuration, it has the following excellent effects.

(b) First, the front end of the evaporator was placed on the buried soil provided at the front end of the lower case to tilt it, and then an opening was made in the upper case so that the evaporator could be pulled out horizontally, so the evaporator could be opened without removing the lower case. Easy to attach and detach, improving serviceability.

(b) Since a weir is provided at the front end of the lower case, the raised parting line is advantageous against water leakage.
