Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a method for improving functionality without changing the entire indoor unit even if the functionality of specific functional parts that make up the indoor unit improves. This invention relates to an indoor unit of an air conditioner that can improve the performance of air conditioners.

(Prior Art) In general, an indoor unit of an air conditioner is known as a wall-mounted indoor unit a that is installed on an indoor wall as shown in FIG. , a control section, a suction port, an air outlet, and other functional parts are integrally assembled.

(Problem to be solved by the invention W1) By the way, the functions of all the functional parts that make up the indoor unit are being improved in order to improve the comfort of the living space, and the functions are improving year by year. ing. but,
It is rare for the functions of all parts to improve at the same time, and the degree of improvement is different, so even if the function of one functional part, such as a blower, is improved, the functional parts are not integrated into the indoor unit. Therefore, the only option is to change the entire indoor unit.For this reason, it would be disadvantageous in terms of cost, etc. if the entire indoor unit was changed every time the function of a part was improved to improve the function of the indoor unit. There are many.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is an indoor unit of an air conditioner that can improve the functionality of a specific component without changing the entire indoor unit. provide: aim to provide.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides an air conditioner indoors, such as a pump, a heat exchanger, a control section, a suction port, an air outlet, etc. This is an air conditioner σ indoor unit that is constructed by connecting at least one of the functional parts constituting the unit to form a single unit, and these units are connected to each other.

Further, the above-mentioned single unit is composed of a first unit consisting of a suction port and a control section a, a first unit consisting of an air blower, and a third unit consisting of a heat exchanger and an air outlet.

(Operation) According to the above configuration, 11! Since an indoor unit is constructed by connecting individual units each made up of at least one functional component, if the functionality of one of the functional components, such as a blower, improves, only the unit in which the blower is incorporated is changed. This allows the functionality of the indoor unit to be improved without changing the entire indoor unit.

Further, when the single unit is composed of a first unit including a suction port and a control section, a second unit including a blower, and a third unit including a heat exchanger and an air outlet, the control section, Since the blower and heat exchanger are built into separate units, even if you change only the unit that improves the function of the part, there is almost no effect on other parts, so it is more certain that costs will be reduced. The functionality of the indoor unit can be improved without any problems.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, ■ indicates an indoor unit of an air conditioner, and in the illustrated example, this indoor unit 1 includes a suction control unit U19, a heat exchange unit U2, a fan unit U3, and a blowout unit U5. It is composed of.

The suction control unit U19 is configured as an independent unit U, with the suction port 2 disposed on the side surface and the control section 3 disposed on the side opposite to the internal connection surface. Suction control unit U
19, the heat exchange unit U2 has a heat exchanger 4 inside.
However, the fan unit U3 has an air blower 41 (fan) 5 inside.
However, the blow-off unit U5 has a blow-off port 6 disposed on its side surface, and is configured as an independent unit U.

These units U19. U2. U3. U5 is each formed in the shape of a rectangular parallelepiped and can be freely connected in the long plane direction,
The suction control unit U19, the heat exchange unit U2, the fan unit U3, and the blowout unit U5 are connected in sequence.

Each unit U19. U2. U3. The connection surface of U5 is formed into a substantially same shape, and is provided with a ventilation hole 7 and a drain pipe passage 8, respectively, so that the ventilation hole 7 and the drain pipe passage 8 fit into each other when the units are connected. It has become. Also, each unit U19. U2,03. LJ5 is electrically connected. Note that the arrow in the figure indicates the direction of air flow.

Next, the operation of this embodiment will be explained.

The indoor unit 1 is constructed by sequentially connecting the suction control unit U19, the heat exchange unit U2, the fan unit U3, and the blowing unit U5 in a line in the horizontal or vertical direction, as shown in FIG. This indoor unit 1 is installed on a wall or the like, and when the blower IN (fan) 5 in the fan unit U3 is driven, the air near the suction port 2 is
and is sucked into the suction control unit U19. At this time, since the control section 3 is provided in the suction control unit U19, the control section 3 is cooled by the suction air, so that heat generation in the control section 3 can be prevented.

The sucked air flows into the heat exchange unit U2,
After exchanging heat with the heat exchanger 4, the fan unit U3
The air passes through the blow-off unit U5 and is blown out from the blow-off port 6.

Therefore, at least one of the functional parts (fan 5, heat exchanger 4, control #3, suction port 2, air outlet 6) constituting the indoor unit 1 can be used as an independent unit U (@include control unit U19, heat exchanger unit U2, fan unit U3, blow-off unit U5), and these units U19. U
2. The indoor unit 1 is constructed by connecting U3 and U5. Therefore, even if the functions of the functional parts that make up the indoor unit 1 are not improved, if the functions of the improved functional parts, such as the fan 5, are improved, the entire indoor unit 1 can be changed by simply changing the fan unit U3. The functionality of the indoor unit 1 can be improved without any problems.

In addition, since separate units U are configured for each function,
Manufacturing of each unit U becomes easy, and its shape can be freely set. Therefore, if the unit U is formed into a triangular prism shape and placed at the joint between the ceiling and the wall (part of the corner) or the joint between the walls, the configured indoor unit 1 can be , as shown in Figure 3,
It can be placed at joints, like a ceiling overhang, giving it a cleaner look and improving its aesthetics.

Furthermore, since there is a degree of freedom in the ventilation path between the inlet 2 and the outlet 6, air purification and ventilation functions can be added freely, allowing for optional units such as air purification units and ventilation units. If it is oval shaped so that it can be connected with almost the same shape as the above-mentioned single unit U, it will be easy to create an optional unit.
It is possible to configure an indoor unit 1 that incorporates y.

Furthermore, since the indoor unit 1 is constructed by connecting individual units U, the refrigerating capacity etc. can be adjusted arbitrarily by changing the unit U of the same type, for example, the heat exchange unit U2 that performs the function of the heat exchanger 4. Can be set to . In addition, the position of the suction port 2 can be arbitrarily placed from the center to the edge of one wall! This allows for optimal air conditioning.

Furthermore, as shown in FIG. 4, the above-mentioned independent unit U includes a suction M control unit U19 as a first unit consisting of a suction port and a control section, and a second unit U19 consisting of a blower (fan).
A fan unit U3 as a unit and a heat exchange blowing unit U21 as a third unit consisting of a heat exchanger and a blowing outlet form an ellipse, and these units U19. U3. U2
1 in sequence as described above, indoor unit 1
is configured.

With this configuration, when the functions of the parts are improved, the functions of the indoor unit 1 can be improved more reliably without being disadvantageous in terms of cost or the like. That is, since the suction inlet and the outlet are provided on the side of the unit U, even if their functions are improved, it will not affect the parts arranged inside the unit U, but the control section inside the unit U, As the functionality of the fan and heat exchanger improves, the structure within the unit U may change, which may affect other parts within the unit. For this reason, as mentioned above, since the control section, fan, and heat exchanger are built into separate units U, changing only the unit U whose parts have improved functions will not affect other parts. Since there are hardly any, the functions of the indoor unit 1 can be improved more reliably without being disadvantageous in terms of cost.

Furthermore, since the control section, fan, and heat exchanger are incorporated into separate units U, maintenance of these functional parts can be easily performed.

In addition, examples of the independent unit U include those shown in Table 1 below.

Table 1 Examples of indoor units constructed using arbitrary units U shown in this table are shown in FIGS. 5 to 8.

Figure 5 shows the length of the indoor unit (combined length) L, which is adjusted to suit a Japanese house, from 1 ken (approximately 1800 m) to 0.5 ken (approximately 920 m).

As shown in b) and (c), a common suction heat exchanger unit U6 may be arranged in the center, and this unit U6 may be provided with a partition plate 10 that partitions the air flow to the left and right.

In this way, by arranging the left and right sides symmetrically, it is possible to control the flow rate to the two heat exchangers with one flow control unit.
There is yt.

FIG. 7 is a configuration diagram showing a unit configuration incorporating an air cleaning function and a ventilation function.

FIG. 8 is a configuration diagram showing an indoor unit arranged vertically and horizontally, and is an example in which an inlet is arranged near the floor and an outlet is arranged near the ceiling. If you do this,
The air near the floor is sucked in from the suction port, and the air is drawn into five units Ul, U7°IJ20. U18. After passing through U8, the air is blown out from the air outlet near the ceiling, so the air flows from top to bottom, allowing efficient air conditioning.

In addition, if there is a tree protruding at the joint between the wall and ceiling where the individual unit U that makes up the indoor unit is placed,
The unit, for example, the heat exchange unit U2, is provided with a recess 11 at a position corresponding to the protrusion of the tree, as shown in FIG.

Even in this case, since the shape of the unit U can be freely set, the configuration of the indoor unit will not be affected to the same extent.

Furthermore, if air exchanges heat with the heat exchanger 4, how should the heat exchanger 4 be arranged within the unit U such as the heat exchange unit configuration? For example, the inside of the unit U may be arranged vertically so as to be partitioned in the horizontal direction, or it may be arranged diagonally so that the air passes through the heat exchanger 4, as shown in FIGS. 2 and 10. The heat exchanger 4 may be of any type as long as it exchanges heat with air, such as a finned tube type heat exchanger or a corrugated fin type as shown in FIG. A heat exchanger may also be used.

Furthermore, the air outlet 6 provided in the air outlet unit configuration, etc.
As shown in Figure 12, it is divided into two stages in the vertical direction,
Air may be blown out horizontally in the upper tier and vertically in the lower tier. In this case, the air outlet 6
By tilting as shown in FIG. 12(b),
It is possible to effectively create speech bubbles in both the horizontal and vertical directions.

The dimension j1 on the air inlet side in the height direction of the air outlet 6 and the dimension 1□ on the opposite side are 1. The air outlet 6 is formed to have an angle of <1□. By doing so, the air volume and wind speed can be made uniform throughout the air outlet 6, and the air emitted from the connection surface side of the air outlet 6 can be prevented from being biased. Further, as shown in FIG. 13, the blowing unit U5 is
The blow-off ports 6 may be formed to blow out air in the longitudinal direction and in a direction perpendicular or perpendicular to the longitudinal direction.

Further, the fan 5 sucks air from the suction port 2 of the configured indoor unit 1, passes it through the heat exchanger 4, and then passes it through the air outlet 6.
Any type of fan may be used as long as the air is blown from the air, for example, a counter-rotating fan as shown in Fig. 2 or a spiral fan as shown in Fig. 14.
