The present invention relates to an air conditioner configured to operate as a mechanical device to supply air conditioned to a room, as well as to discharge unnecessary air, and in particular, the present invention relates to a self contuined air conditioner having the above capability. It relates to a device for moving the discharge gate in the device.

Air conditioning units, which are usually used for residential and similar applications, are generally contained in a single case. The case is usually divided into two parts, the evaporator and the condenser, each of which is fitted with a blower to turn the air inside. At this time, the evaporator is in contact with the indoor air to harmonize, the condensation is in contact with the outside air. The coolant flows by taking heat away from the indoor air and discharging it to the outside through an independent circuit.

In addition to the ability of an air conditioner to supply air controlled at an appropriate temperature to the room, it is desirable to have a device for discharging unnecessary air from the room to the outside.

This method is accomplished by placing an outlet in a partition that divides the evaporator and the condenser. Part of the air in the room enters the evaporator and enters the condenser that is in contact with the outside air through the outlet by the blower of the evaporator and the condenser.

Due to the optional operation in which the outlet is opened when the machine is operated in a form in which some unwanted indoor air is discharged, and the outlet must be closed when operating in a manner that harmonizes the indoor air, the inner door covers the outlet and is A control mechanism is provided to keep the at a proper position.

Conventional door control mechanisms, such as in U.S. Patent Nos. 3, 932, 157, 3, 921, 416, 3, 823, 514, 3, 149, 028, etc., all assigned to the assignee, are relatively complicated, It also required considerable skill and effort in assembling them. Moreover, the power tool was quite awkward to operate the door and also needed considerable force to change position. Also, in the previous form, it was quite difficult to approach inside to trim machinery.

It is an object of the present invention to provide an improved apparatus for discharging unnecessary air from the room in an air conditioning apparatus.

Another object of the present invention is to provide a device made to selectively open and close the outlet of the independent air conditioner in order to discharge the air from the closed space cooled by the air conditioner.

It is still another object of the present invention to provide a device which is economically manufactured, repaired, simple in structure, easy to operate, and which can reduce the number and size of parts.

Other objects will be described in detail from the appended claims. These objects are achieved by installing a door in a preferred embodiment of the present invention, ie, a pivotally mounted outlet covering and configured to be closed by a spring. The sliding feeder, which is operated using a pushbutton positioned adjacent to a tab extending from the door, shifts its position against the spring action and actuates a tab that opens the door. The pin, which is mounted on an elastic arm fixed to the conveying device and is in contact with an inclined surface having a plurality of surfaces angled from the direction of movement of the conveying device, passes through the surfaces as the conveying device moves.

When the push button is first pressed and released, the position of the conveying device is changed, and the pin passes through any inclined surface, but stays in at least one fixed position by the surface to keep the door open. When the pushbutton is pressed and released a second time, the pin passes through the other inclined surface and returns to its original position to close the door. It is to be understood that the embodiments of the present invention described below are adapted for use in a standalone air conditioner of a so-called indoor air conditioner having a partition separating the evaporator and the condenser, but may also be adapted to other air conditioners. Incidentally, in the following preferred embodiment, although there is a single outlet, often a plurality of outlets may be used, and in this embodiment, the door apparatus may be a plurality of doors.

In FIG. 1 a schematic view of an air conditioner is shown. The apparatus comprises a casing 4 with a bottom plate (not shown) on which several parts are mounted. The partition wall 5 is divided into an evaporator 6 including an evaporator 7 and an evaporator blower 10 and a condenser 8 including a condenser 9 and a condensation blower 12. The device is composed of an evaporator in contact with the indoor air and a condenser in contact with the outside air to be installed indoors. Although not shown in the figure, the condenser and evaporator are part of a conventional refrigeration circuit having a compressor and an expander. The evaporator absorbs heat from the room and the condenser releases heat to the outside. The outlet port 14 covered by the door 16 is installed in the partition wall 5 which divides the condensation part and the evaporation part so that they communicate with each other. The evaporative blower 10 forms a front of the air car sufficient to exhaust the air from the room, which is drawn from the room and enters the evaporator through the outlet 14 (when the door 16 is open) into the condenser. By the mixing operation of the condensation blower and the evaporation blower, the air is discharged out of the condenser through the outlet 14.

2 to 6 show a device for controlling the opening and closing of the outlet 14. The outlet 14 in the partition 5 is covered with a door 16. The tab 22 is integrally attached to the door 16 and protrudes through the slot 18 in the partition 5 perpendicular to the door. The door 16 and tab 22 are firmly mounted for the pivoting of the slot 18. The bracket 20, which is a component of the partition 5, is located on the partition opposite to the outlet 14 from the tab 22. One end of the compression spring 24 is attached to the bracket 20, and the other end is attached to the tab 22, so that the tab 20 is pressed away in the direction away from the bracket 20, and thus the outlet of the compression spring 24 is closed ( Support the door 16 covering 14).

A set of guides 26 is mounted opposite the tab 22 from the outlet 14, which consists of four vertical thin walls with respect to the partition arranged in parallelogram. The conveying apparatus 28 which consists of a rectangular frame is mounted so that it can move back and forth electrically by a guide. The upper part of the lower wall 66 of the parallelogram guide and the lower part of the upper wall 68 of the parallelogram are sliding surfaces on which the outer edges of the conveying device 28 move.

Guide openings 70 are formed in the two vertical walls from the partition walls, which are wide enough to allow loose coupling with the conveying device 28 and extend over the entire height of the parallelogram. The conveying device 28 has one end directly in contact with the tab 22 and the other end is attached to the actuator with the push button 30. When a force is applied to the push button 30, the transfer device is repositioned to meet the tab 22 past the guide 26. When the tab 22 is moved against the action of the spring 24, the door 16 is opened, and the door 16 is closed by the return force of the spring 24 and the conveying device 28 is returned to its original position.

As shown in FIGS. 2 and 3, the elastic arm in the plane adjacent the tab 22 is integrally attached to the end of the conveying device 28 and parallel to the plane of the partition wall 5 inside the frame of the conveying device. There is 34. The elastic arm 34 is flexible in all directions, but has a resting position so as not to be stressed or displaced in the plane of the conveying device.

The lamp 32, which is mounted on the partition 5 and is integrally formed, consists of a relief which provides a plurality of discontinuous sliding surfaces by the relief surface. At the end of the elastic arm 34, a pin 36 is mounted perpendicular to the partition wall 5 together with the pin shaft portion, which is in contact with the sliding surface of the lamp 32. As shown in FIG. The lamp 32 is located on the partition wall 5 so that the pin 28 can come into contact with the sliding surface of the lamp as the conveying device 28 moves together with the elastic arm 34 and the pin 36. The direction of movement 56 of the conveying device 28 is shown in FIG. 6, which shows an enlarged front view of the lamp 32. As shown in FIG. A line showing the rest position of the elastic arm 54 at various positions as the transfer device 28 moves is indicated parallel to the direction of motion 56.

Position 58 shows the position of the pin 36 along the ramp 32 at which the opening and closing cycle of the door begins. As a force is pushed by the push button and the conveying device 28 moves from right to left in FIG. 6, the pin is cam surface on the ramp along the resting position 54 of the passageway of the elastic arm from position 58. Move until you reach 38. As the feeder continues to move to the left, the pin moves the cam surface 38 until it reaches the connecting surface 52, while at the same time the elastic arm moves in the rest position as the pin moves the cam surface 38. You will continue to move. The connecting surface 52 is semicircular to connect the first holding surface 40 and the cam surface 38. As the feeder continues to move to the left, the pin passes through the connecting surface 52 and the pin moves closer to the resting position as a result of the elastic arm being suppressed toward the resting position by the displacement of the elastic arm. The first holding surface 40, the second holding surface 42, the inclined cam surface 44 and the first stop surface 48 form a brass to support the pin when the pin leaves the connecting surface 52. Movement to the left of the conveying device 28 is stopped by the limiting surface 62 of the push button 30 which comes into contact with the guide 26.

When the conveying device is completely moved to the left, the pin 36 passes through the connecting surface 32 and comes into contact with the most stationary surface. When the force applied to the left is removed, the spring 24 moves by the motion of the spring 24 until the pin stops at the portion 60 in contact with the first holding surface 40, the second holding surface 42, or the inclined cam surface 44. The device 28 and the pin return to the right. When the pin is moved to this position by the return force by the spring, the conveying device 28 is moved and the door is kept in the open position.

When the conveying device 28 moves from right to left again by applying the second linear motion force, the pressing force of the elastic arm 34 causes the pin to move partially on the inclined cam surface 44. The inclined cam surface 44 forms an acute angle with the partition wall and the base of the cam surface is within the partition wall 5 surface, wherein the surface 44 is inclined upward from the partition surface toward the elastic arm in the resting position. (All other lamp sliding surfaces are perpendicular to the partition 5).

As the pin continues to move left along the inclined cam surface 44, the pin is in contact with the second stop surface and the second stop surface 50 is angled with respect to the direction of motion of applying the force to the pin. If the pin continues to move left, the pin will slide along the second stop surface and the inclined cam surface until it completely passes the inclined cam surface 44.

At that position the elastic arm returns the pin to position 64 where the elastic arm resting position 54 is on the line. The pin also returns to the position of the original distance from the partition 5 by the reverse pressure formed on the elastic arm by passing over the inclined cam surface 44. Movement to the left of the conveying device 28 is stopped by the limiting surface 62 of the push button 30 in contact with the guide 26.

When the force applied to the push button 30 is removed, the feed device and the pin are moved from the left side to the right side of FIG. 6 by the operation of the spring 24. The pin 36 moves along the line of the elastic arm resting position 54 until it is adhesive with the return surface 46 at position 64. As the feeder moves to the right of the base, the pin continues to move along the feedback surface 46 until it reaches the intersection of the feedback surface 46 and the cam surface 38. As the conveying device moves further to the right, the pin passes over the intersection and quickly retracts from position 58 to elastic arm resting position 54 as a result of the suppression formed by the displacement. This position is the starting point of the entire cycle and is the closed position of the door 16.

The conveying device is stopped by the limitation of the spring force as the pin 36 is in contact with the guide 26 and the movement to the right is also brought into the closed position of the door 16. It is obvious that another stop surface can be added in the ramp to limit the movement of the feeder. And it is clear that additional lamp surfaces can be applied to the instrument to provide an additional brass to keep the door in an intermediate position.

In order to easily construct the structure, the above-mentioned door control mechanism is made of four parts. The partition walls 5, the brackets 20, the guides 26 and the lamps 32 having all surfaces are cast by a single plastic mold. The conveying device 28, the push button 30, the elastic arm 34 and the pin 36 are cast by another single plastic mold. The third part, the door 16 and the tab 22, is also cast by a single plastic mold. The fourth part is a spring 24.

The mold of the door and tab is assembled by inserting the tab through the groove 18 in the partition. The compression spring is assembled by inserting each spring end, that is, one end into a hole suitable for the bracket 20 and the other end into the tab 22. The conveying device piece is inserted through the opening 70 in the guide 26, at which time the elastic arm 34 is displaced to allow the head of the pin 36 to pass through the insertion hole 72 in the guide 26. If it passes through the insertion hole of the elastic arm, the displacement is released.

The decomposition of the invention simply reverses the above process.

The control device can be used to control other parts of the air conditioning device, such as switches or other physical actuation devices. And a filler such as filler 19 in FIG. 3 can be inserted into a hole 18 that firmly supports for pivoting the door and tab.

In the preferred embodiment of the present invention described above, it is apparent that it is possible to provide an internal door control device of an air conditioner which is economical, easy to assemble and requires relatively little maintenance.
