JPS5915734A - Ventilating device of monobloc type air conditioner - Google Patents

Abstract

PURPOSE:To prevent foreign matters from entering through the opening of a partition plate by a constitution wherein the openings for mounting a dust proof net are respectively provided on an indoor and an outdoor partition plates of a unit and furthermore the dust proof net and an opening closing damper are mounted on each opening in the ventilating device of the monobloc type window air conditioner. CONSTITUTION:The opening 7 is provided on the partition plate 5. A net part 15 is mounted so as to oppose to the opening 7 when the catch part 14 arranged at the left end of the dust proof net 16 is hanged to the opening 7. The projections 17 of a door 18 are mounted by piercing the holes 21 of the dust proof net 16 and the holes 22 of the partition plate 5. The door 18 is fixed to the partition plate 5 by the elastic expansion of the projections 17 after their piercing of the holes 22. The door 18 is open and closed about an axis 9, however foreign matters are prevented from entering from outside by means of the dust proof net 15.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a ventilation system for an integrated air conditioner installed in a window or the like.

Conventional Structure and Problems Conventionally, this type of ventilation structure has been structured as shown in FIGS. 1 to 3. That is, in the same figure, looper 1
An inside/outside partition plate 5 (hereinafter referred to as a partition plate) that separates the interior of the outer box 2 into an indoor side 3 and an outdoor side 4 is provided with an opening on 2 sides so that indoor air 6 can be ventilated. A door 10 made of synthetic resin is provided in the opening 7 so that the opening 7 can be sealed during normal freezing cycle operation. This door 10 is attached to the partition plate 6 by fitting the protrusion 11 into the hole 13 of the partition plate 5 through a hinge part 9 made of synthetic resin so that the door 10 can be opened and closed manually by a wire 8. There is. Said hole 13
is formed so that its diameter is slightly smaller than the maximum diameter portion 12 of the projection 11, and by inserting the projection 11 using the elasticity of the resin, the door 1o is fixed in a position where the opening 7 can be opened and closed. be done.

However, in this type of conventional ventilation structure, when the door 10 is in an open state, f'L and fv are provided in the outer box 2.

Foreign objects such as insects may pass through the looper 1 and cause the partition plate 5 to open [
” He was annoyed at the fault of members of club 7 invading the room.

Purpose of the Invention Therefore, the present invention aims to prevent foreign matter from entering through the opening 7 of the partition plate 5.

Structure 3 of the Invention In order to achieve this object, the present invention provides a dustproof screen at the opening of the partition plate.

Description of examples An embodiment of the present invention will be described below with reference to FIG. 4 of the accompanying drawings.

This will be explained with reference to FIG. Components that are the same as those in the conventional example will be described using the same numbers. Further, since the structure of the integrated air conditioner is the same as the conventional one except for the opening 7, illustration and description thereof will be omitted.

In the figure, the dustproof screen 16 is made of synthetic resin, and has a hook at one end that engages with the edge of the opening 7 so that it can be fitted and fixed into the opening 7 of the partition plate 5 by utilizing the elasticity of the resin. 1
Furthermore, a hole 21 slightly larger than the maximum diameter part 20 of the protrusion 17 is formed at the same position as the protrusion 17 of the door 18 on the opposite side of the hook part 14 across the rope part 15. has been done. Reference numeral 22 denotes a hole formed in the partition plate 5, and its diameter relationship with the projection 17 is the same as in the conventional case. Then, the protrusion 17 of the door 18 passes through the hole 21, and furthermore, the partition plate 6
The maximum diameter portion 20 of the protrusion 17 is expanded and fixed by the elasticity of the resin, passing through the hole 22 provided in the protrusion 17 . In this state, the door 18 and the dustproof screen 16 are fixed to the partition plate 5 as one body, and the dustproof screen 16 is further sandwiched between the partition plate 5 and the door 18.

Therefore, the dustproof net 16. The door 18 is installed by newly attaching the dustproof screen 16 to the opening 7 of the conventional partition plate 6 by hooking the resin hook part 14 to the edge 19 of the opening 7 of the partition plate 5. The process is finished by fixing the door 18. This dustproof net 16 can prevent foreign matter such as insects from entering from outside the room. Further, since the dustproof net 16 is provided with the hook portion 14 as shown in FIG. 4, it can be fixed to the opening 7 of the partition plate 5 easily and more reliably.

Effects of the Invention As is clear from the above embodiments, the present invention provides a dustproof net over the ventilation opening formed in the partition plate, and this dustproof net prevents insects or dust from entering, thereby providing a comfortable environment. It has the effect of providing ventilation.
