Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a built-in heating, cooling, and air-conditioning device that is installed in a general house and performs air conditioning.

Conventional technology Conventionally, this type of heating and cooling air conditioner was
As shown in Japanese Patent No. 122022, the indoor air passes through a heat exchanger in the ventilation path, passes through a ventilation path provided in the storage furniture, and is blown into the room from the outlet.

Problems that the invention aims to solve However, with this type of structure, the airflow blown out from the wall is from the same outlet for both cooling and heating, so it cannot fulfill its original function as an air conditioner. do not have.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to switch the blowing direction of cold air and warm air in the air outlet passage of the air conditioner, and to You can air condition any room.

Function: With this configuration of the present invention, cold air is blown out from the air outlet provided above the duct of the storage furniture. The air conditioning of the adjacent room using storage furniture as a partition can be performed by blowing out from the outlet on the back of the storage furniture.

In addition to providing air conditioning effects with good temperature distribution during both cooling and heating operations, the air conditioning system in opposing rooms is operated by separate air conditioners, and has the same functionality as a multi-air conditioner that can switch between one outdoor unit and two indoor units. It can be made to last.

Embodiment Hereinafter, an embodiment of switching between cooling and heating in the air conditioner of the present invention and switching between air-conditioned airflows between adjacent rooms will be described with reference to the drawings.

Figure 1 shows an embodiment in which the air conditioner of the present invention is installed in a house, and is composed of an air outlet duct 2 connected to the air conditioner main body 1, an intake duct 3, and a duct 4 built into a storage furniture 5. ing. The built-in duct 4 is composed of an opening 7 and an opening 8 on the storage furniture door 6 side, and an opening 10 and an opening 11 on the back side 9 of the storage furniture 5, as shown in FIG.

Air blown by a blower 12 in a wind circuit within the air conditioner main body 1 is cooled by a heat exchanger 13, and then passes through a blow-off duct 2 to a built-in duct 4. The lower opening 14 and the opening 15 of the built-in duct 4 are connected to the airflow switching section 16 of the blow-off side duct 2, and are defined as an opening 17 for the lower opening 14 and an opening 18 for the lower opening 15. Note that there is a rotating partition plate which has a partition wall 19 that vertically separates the duct between the opening 8 and the opening 11 of the built-in duct 4, and can close either the upper part of the lower opening 14 or the upper part of the lower opening 15. 20 rotates 180 degrees around axis 21.

Now, when the rotary partition plate 20 is tilted toward the opening 8 side, the ventilation passage from the lower opening 14 leads only to the opening 8, and from the lower opening 15, the ventilation passage opens to the opening 7, the opening 10, and the opening 8. Leads to 11. When the openings 10 and 11 are closed, the ventilation path of the opening 15 becomes only the opening 7.

The air cooled by the cooler 13 passes through the blow-off duct 2, is switched by the airflow switching section 16, and reaches the ventilation passage 22 via the opening 18 and the lower opening 15.

If you want to air condition the room on the door side, use the rotating partition plate 2.
0 is tilted toward the opening 8 side, and the ventilation passage 22 communicates with the upper ventilation passage 23. If the openings 10 and 11 are closed in the manner described below, the cold air blown from the opening 7 will cool the room and then flow through the opening 8 and pass through the lower opening 14 and opening 17 through the ventilation path 24. After that, it returns to the suction side duct 3.

In the case of heating operation, the air flow is reversed, and the warm air blows out from the outlet duct 2, the switching part 16, the opening 17, the lower opening 14, the ventilation path 24, and the opening 8 of the built-in duct 4 into the room. Speech out. An opening 7, a ventilation passage 23, a ventilation passage 22, for the return airflow after heating.
It returns to the suction duct 3 via the lower opening 15, the opening 18, and the airflow switching section 16.

The above describes the heating and cooling of the room on the door 6 side of the storage furniture 5, but next we will discuss the heating and cooling of the room on the back 9 side of the storage furniture 5.

When cooling the adjacent room on the back 9 side, the rotating partition plate 20 of the built-in duct 4 is tilted toward the opening 11 side, and the ventilation path 2
4 and the ventilation passage 23 to allow ventilation, and it is necessary that the door-side opening 7 and opening 8 be closed by the method described below.

First, in the cooling operation, the airflow switching unit 16 is switched so that the cold air comes out from the opening 17 in the opposite manner to the door side described above, and the cold air is sent to the lower opening 14 of the built-in duct 4.
The air is blown out from the opening 10 through the ventilation path 24 and the ventilation path 23. During heating, warm air is blown out from the opening 18, passes through the lower opening 15, the ventilation path 22, and then is blown out from the opening 11. The return airflow after heating enters through the opening 10 and reaches the main body opening 17.

In addition, each opening has a wind direction changing grill 2.
5, 26, and 27, and a wind direction changing grill 28 is attached to the opening 11. FIG. 2 shows a lower section of the built-in duct 4, and FIG. 5 shows an upper section of the built-in duct.

As shown in Fig. 6, the wind direction changing grill is composed of a grill frame 29 and a wind direction changing plate 30, and the wind direction changing plate 30 rotates around a shaft 31 provided at its center to change the blown airflow to the left or right. and adjust the temperature distribution and airflow distribution in the room. When the wind direction changing plate 30 is rotated more widely, its ends 26 and 27 come into contact with the protrusions 32 and 33 provided inside the grill frame 29, thereby closing the opening of the grill frame and stopping the airflow.

As mentioned above, when heating or cooling the room on the side of the storage furniture door, close the wind direction changing grills at openings 10 and 11, and when heating or cooling the adjacent room on the back side of the storage furniture, close the wind direction changing grills at openings 7 and 8. close.
This storage furniture must be installed alongside other furniture and constructed so that there is no ventilation with adjacent rooms, especially on the ceiling side.

Effects of the invention This invention has a structure in which an air conditioner is housed in storage furniture used for partitioning a house, and in order to obtain a comfortable heating and cooling effect, the air conditioner is blown out from the top of the room.
During heating, air is blown from the bottom, especially near the feet, and a single air conditioner can air-condition an adjoining room with partition storage furniture by closing and opening the wind direction change grill installed in the built-in duct. Furthermore, a variety of effects can be produced with a relatively simple switching operation.
