Description

[Detailed description of the invention] This invention attempts to supply comfortable cool and warm air to the room at any time, by blowing warm air from below the aircraft when heating the room, and blowing cold air from above the aircraft when cooling the room. The present invention relates to an air conditioner equipped with a cooling/heating air switching device in an air conditioner/heater.

When heating and cooling a room, instead of blowing cold and hot air throughout the room, warm air is applied to the lower part of the human body, that is, the feet, in winter, and cool air is applied to the overhead part during heating and cooling, depending on the season. It is an undisputed fact that molding is extremely effective for quick effects.

For this reason, methods commonly used in dual-purpose air conditioners include replacing the top plate with hot and cold air outlets each time, or moving and reversing the entire blower. It was complicated and difficult to handle, and its functionality was inevitably degraded.

The main purpose of the present invention is to fundamentally solve these drawbacks, and in a dual-purpose air-conditioning/heating machine in which the blower 8 is installed at the lower part of the machine body, the suction port is installed at the upper part of the back of the machine body. 2, a cold air outlet 3 at the top of the fuselage, and a warm air outlet 4 at the lower front of the aircraft, and cold and hot air passages 10 and 1 which communicate the cold air outlet 3 and the warm air outlet 4.
It is an object of the present invention to provide an air-conditioning/heating machine characterized in that a cooling/heating air switching plate 11 is disposed within the air conditioner 0' so as to be movable in changing passages.

Hereinafter, the structure of a specific example of the present invention will be explained in detail with reference to illustrative drawings.
In addition, a cold air outlet 3 and a warm air outlet 4 are provided at the upper and lower front, respectively, and the inlet 2 and the cold air outlet 3 are communicated through a U-shaped air passage 5, and the upper part of the passage is A heat exchange coil 6 and a drain pan 7 are disposed at the top, and a blower 8 is arranged below. A substantially triangular air passage portion is formed in front of the air outlet of the air passage 6, and a partition plate 9 is provided above the air passage portion. The interior of the aircraft is divided into two with cold and hot air passages 10 and 1 on the front side.
0', and communicates with the cold air outlet 3 and the warm air outlet 4, respectively.

Reference numeral 11 denotes a cold/warm air switching plate which is mounted between the air blowing passage 5 and the cold/hot air passages 10, 10' so as to be movable up and down by means of a support shaft 12, thereby blocking either of the cold/hot air passages.

Reference numeral 13 indicates an operating lever for moving the switching plate up and down.

Note that in the illustrated diagram, a manual operation lever is shown, but this is just an example.
It goes without saying that other mechanical or electrical mechanisms can be used to move the .

In addition, as the cooling/heating air switching mechanism, the switching plate 14 is connected to the cooling/heating air passage 1 from the front of the body as shown in FIG.
It is also possible to insert the passage between 0 and 10' so that the passage can be changed freely.

The present invention is constructed as described above, and by moving the switching plate 11 up and down using the operating rod 13, the air blowing passage on either side of the cooling/warming air passages 10, 10' is shut off. In this case, cold air can be separately blown from the upper cold air outlet 3, and warm air can be separately blown from the warm air outlet 4 during heating.

In addition, if the switching plate 11 is placed in an intermediate position, cold or warm air can be blown simultaneously from the upper and lower air outlets 3 and 4 on the upper and lower sides of the vessel. It may also be possible to adjust it arbitrarily.

As described above, the cold/hot air switching device according to the present invention operates the cold/hot air switching plate 11 to direct warm air through the warm air passage 10' from the warm air outlet 4 at the bottom of the container during heating, and to direct cold air through the cold air passage during cooling. 10 and is intended to be blown out from the cold air outlet 3 in the upper part of the vessel body, and the purpose is to separate the cold and warm air into upper and lower parts using one device and supply the desired cold and warm air into the room. In this invention, the air outlet 8
Since a substantially triangular airway portion C is formed in the front of the airway, the air flows naturally and smoothly without any resistance, and the airway also functions as a sound deadening chamber. Because of this, there is no noise or noise, and indoor heating and cooling is very fast and effective.Also, the heating and cooling switching operation is extremely easy and reliable, and the structure is simple, and there is no risk of failure. It can be said that it is an extremely effective and appropriate idea, as there is no hair on the hair.

Moreover, by installing the blower 8 at the lower part of the fuselage, the overall stability of the fuselage is excellent, there is no concern about noise generation, and since the suction port is open at the back, the filter will not be exposed to the outside. It also has the effect of being completely new in terms of design.

In particular, in the present invention, since the front and rear ventilation passages are formed by the U-shaped ventilation passage 5, the ventilation distance is long, and this exhibits a natural silencing effect during ventilation, resulting in very low noise. There is sufficient space for arranging necessary mechanisms such as a drain pan, and the machine has various advantages such as the ability to make the overall shape of the machine extremely compact.
