Description

  The present invention relates to a linked heating system for an air conditioner and an air conditioner, and more particularly to a technique that can control the floor heating apparatus and a general-purpose air conditioner having an infrared light receiving function in conjunction with each other.

  In general, there are warm air heating by an air conditioner and heating from the floor surface by floor heating in the heating of a living room, but there are advantages and disadvantages from the viewpoint of comfort and energy saving. In other words, warm air heating with an air conditioner alone is low in operating cost and energy saving, but the warm air is uncomfortable and the warm air accumulates in the upper part of the room, so it cannot be said that the feet are cold and comfortable. In addition, the floor heating device alone uses radiant heat and can evenly warm the room uniformly and with the feet efficiently, and the head cold foot heat is comfortable, but the operation cost is high and the energy saving is excellent. I can't say that. Furthermore, in the case of floor heating system independent operation, in order to obtain quick warming at the time of start-up, it is necessary to raise the floor temperature and the room temperature. Therefore, the floor heating is overloaded by increasing the set temperature of the floor heating. Power consumption is increased accordingly. Moreover, since Joule heat is used even in steady state operation, there is a problem that a large amount of heat is consumed, heat exchange efficiency is poor, and power consumption is increased.

  FIG. 9 is a graph showing the case where the air conditioner is operated alone, the case where the floor heating is operated alone, and the indoor comfortable temperature range (the area surrounded by hatching in FIG. 9). The relationship between temperature (degreeC), time (minutes), and power consumption (kWh) in the case of heating independent operation is shown by the graph. In the case of this floor heating independent operation, as shown in FIG. 10, the power consumption A ′ at the time of rising is, for example, 4.09 (kWh), and the power consumption B ′ at the time of operation in a steady state is, for example, 6.31 (kWh). In addition, there is a problem that it takes a long time until the room temperature and the bed temperature reach a comfortable temperature.

  Therefore, conventionally, a system has been invented in which a floor heater and an air conditioner are simultaneously operated by transmitting a control signal from one controller to the floor heater and the air conditioner (see, for example, Patent Document 1).

However, in the conventional example shown in Patent Document 1, the controller needs to be installed at a position lower than the air conditioner, that is, a height position where the user (including children) can operate, so the angle between the controller and the air conditioner, The distance increases and infrared rays with strong directivity compared to radio waves are difficult to reach the air conditioner. Or when there is an obstacle between an air conditioner and a controller, it becomes difficult for infrared rays to reach. For this reason, conventionally, there has been a problem that the positional relationship between the air conditioner and the controller is restricted.
JP 2001-235208 A

  The present invention was invented in view of the above-described conventional problems, and can provide a heating environment that is excellent in both economy and comfort, and has a conventional positional relationship between an air conditioner and a controller is limited. It is an object of the present invention to provide an interlocked operation system of a floor heating device and an air conditioner that can solve the problem.

In order to solve the above-mentioned problem, the present invention provides a controller 3 for controlling the floor heating device 1 in which a floor heating device 1 and an air conditioner 2 having a control device and having an infrared light receiving function are installed in one room. An infrared transmission unit 4 that is separate from the controller 3 is provided by wireless or wired connection so as to be at a height position close to the air conditioner 2, and control command information from the controller 3 is transmitted to the infrared transmission unit 4 by infrared rays. The floor heating device 1 and the air conditioner 2 can be linked to each other by converting the signals into signals and transmitting the infrared signals to the air conditioner 2. The infrared transmission unit 4 causes the plurality of LEDs 7 a to 7 d to run vertically. an infrared transmission unit 6 arranged in a row direction, and a parallel axis of rotation orientation of the tandem lined this LED7a~7d, LED7a~7 the plurality of The LEDs 7a and 7d located at one end of the row are arranged to be inclined obliquely toward the arrangement direction as compared with the other LEDs 7b to 7d and 7a to 7c, and the infrared transmitter 6 is rotated. It is characterized by being rotatable around the axis of the shaft.

By adopting such a configuration, it is possible to eliminate the discomfort of warm air during heating as in the case of the air conditioner 2 independent operation by the interlock operation of the floor heating device 1 and the air conditioner 2 and in the case of the floor heating independent operation. Such a problem of high operating costs can be solved at the same time, and a more comfortable and more economical heating environment can be provided. Even if there is an obstacle between the controller 3 and the air conditioner 2 or the controller 3 is installed at a position lower than the air conditioner 2, the infrared transmission unit 4 is connected to the controller 3 from the controller 3. The infrared rays can be reliably transmitted by disposing them at a position where the infrared signals S can be reliably transmitted to the air conditioner 2. Moreover, by configuring the infrared transmission unit 4 separately from the controller 3, the conventional problem that the positional relationship between the air conditioner 2 and the controller 3 is restricted can be solved.
Moreover, it is preferable that the mounting angle of the infrared transmission unit 6 is variable to an angle different by 90 ° in front view so that the rotation axis changes from the vertical direction to the horizontal direction.

  Moreover, it is preferable that a plurality of infrared transmission units 4 can be added to one controller 3 of the floor heating device 1 in accordance with the number of air conditioners 2 to be installed. It is possible to easily cope with the expansion of the air conditioner 2 simply by adding the infrared transmission unit 4 without increasing the number.

  Further, when the infrared transmission unit 4 is added, the infrared signal S is transmitted one by one so that the single air conditioner 2 does not receive the infrared signals S from the plurality of infrared transmission units 4 at the same time. In this case, since the infrared signal S from one infrared transmission unit 4 and the infrared signal S from the other infrared transmission unit 4 are not transmitted at the same time, but shifted one by one, The interference of the infrared signal S can be prevented, and the malfunction of the air conditioner 2 can be surely prevented.

  The present invention provides a system that can easily control general-purpose air conditioners in conjunction with floor heating operation control by relaying an air conditioner control command from a controller to an air conditioner having an infrared light receiving function via an infrared transmission unit. It can be built and can provide a more comfortable and more economical heating environment. In addition, by transmitting an infrared signal to the air conditioner from an infrared transmission unit that is separate from the controller, the conventional problem of limiting the positional relationship between the air conditioner and the controller is solved, and the degree of freedom of the installation position of the infrared transmission unit is reduced. Can be given.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 is an explanatory diagram of a system of the present invention in which a floor heating device 1 and an air conditioner 2 installed in one room are operated in conjunction. The air conditioner 2 is a general-purpose air conditioner having an infrared receiving function, and an infrared signal S from an infrared transmission unit 4 described later is transmitted to the air conditioner 2 (infrared receiving unit of the indoor unit) attached to the wall surface. The control device performs various controls such as temperature setting, air volume setting, operation on / off, and the like.

  The floor heating apparatus 1 is configured by an electric heating floor heating panel in which an electric heating mat is laid on the lower surface of a floor board and the controller 3 electrically controls the electric heating mat, for example. Of course, it is not limited to the electric heating type, and it may be a hot water type floor heating panel or the like in which a heating pipe is provided on the lower surface of the floor board and the controller 3 controls the amount of hot water flowing into the heating pipe.

  The controller 3 that controls the floor heating device 1 is attached to a height position at which a user (including children) can operate, for example, a wall surface having a height of about 1 m from the floor surface (or a floor surface is also acceptable). In the controller 3, for example, a floor heating operation unit for operating only the floor heating device 1 alone, an air conditioner operation unit for operating only the air conditioner 2 alone, and the floor heating and the air conditioner 2 are operated in conjunction with each other. For this purpose, a floor heating-air conditioner-operated operation unit is provided.

  Information on the control command of the air conditioner 2 by the operation of either the air conditioner operation section of the controller 3 or the floor heating-air conditioner linked operation operation section is once sent to the infrared transmission unit 4 through the electric wire 11 as an electric signal. The infrared signal is converted into an infrared signal S by the infrared transmission unit 4. The infrared transmission unit 4 is configured separately from the controller 3 and is attached at a position separated from the controller 3. That is, the controller 3 is mounted at a height position that is easy for the user to operate, but the infrared transmission unit 4 that does not need to be operated by the user is mounted at a height position close to the air conditioner 2, for example. Here, the air conditioner 2 is installed at a height position substantially opposite the front position.

  As shown in FIG. 3, the infrared transmission unit 4 includes a fixed frame 5 fixed to a wall surface and an infrared transmission unit 6 attached to the fixed frame 5. The infrared transmission unit 6 converts information on the control command of the air conditioner 2 from the controller 3 into an infrared signal S (remote control signal). In this example, four LEDs 7a to 7 in a hemispherical transparent casing 6a. 7d is arranged in a vertical row. In addition, it is desirable that only the uppermost LED 7a is disposed to be inclined obliquely forward and upward C, and the remaining three LEDs 7b to 7c are disposed toward the front front surface E. In this example, the inclination angle θ1 (FIG. 3D) of one LED 7a located at the top is set to several tens of degrees, for example. Further, the infrared transmission unit 6 in which the LEDs 7a to 7d are arranged in a vertical row is rotatably supported so as to be able to swing in the left-right direction D with respect to the fixed frame 5 fixed to the wall surface. The direction of ˜7d can be changed to the left and right. As a mechanism for rotating the infrared transmission unit 6 in the left-right direction D, upper and lower shaft portions 8 are protruded from both upper and lower ends of the infrared transmission unit 6, and the upper and lower shaft portions 8 are rotatable at both upper and lower positions of the fixed frame 5. Is pivotally supported.

  Then, when the floor heating-air conditioner linked operation unit of the controller 3 is operated, a floor heating control command is transmitted to the control device of the floor heating device 1 via the power cord 10 (FIG. 1), A control command for the air conditioner 2 is transmitted as an infrared signal S to the control device of the air conditioner 2 via the infrared transmission unit 4. By using a signal that can be received by the general-purpose air conditioner 2 as the infrared signal S, the general-purpose (existing) air-conditioner 2 can be used as it is. A linked operation system of the air conditioner 2 can be constructed. Further, since the controller 3 and the infrared transmission unit 4 are configured separately, there is an obstacle between the controller 3 and the air conditioner 2, or a position lower than (or far from) the air conditioner 2. ), The infrared transmission unit 4 can be separated from the controller 3 and installed at a position where the infrared signal S can be reliably transmitted to the air conditioner 2. In addition, by configuring the infrared transmission unit 4 separately from the controller 3, the degree of freedom of the installation position of the infrared transmission unit 4 is solved while solving the conventional problem that the positional relationship between the air conditioner 2 and the controller 3 is limited. Can be held. That is, the infrared signal S from the infrared transmission unit 4 can be smoothly transmitted to the air conditioner 2 without being restricted by the position, angle, distance, and the like with the air conditioner 2.

  Here, when the floor heating / air-conditioner linked operation part of the controller 3 is operated, simultaneous operation control in which the floor heating device 1 and the air conditioner 2 start operation simultaneously is possible. In consideration of the above, a time difference operation control method is adopted in which the air conditioner 2 is first operated alone and the operation of the floor heating device 1 is started after the room temperature rises above a certain level. That is, the room temperature is raised in advance by single operation of the air conditioner 2, and the operation of the floor heating device 1 is started when the room temperature reaches a certain temperature or higher. At this stage, since the room temperature and the floor temperature are warmed by the air conditioner 2, a large amount of heat is not required to raise the floor temperature to a certain temperature by the floor heating device 1, and as a result, the power consumption at startup is kept low. Will be able to. Furthermore, at the time of floor heating and air-conditioner linked operation, since the room temperature is automatically controlled by the air conditioner 2, the floor temperature does not fall below a certain temperature.

  The experimental results of the present invention are shown in FIG. FIG. 2 shows the relationship between the temperature (° C.), the time (minutes), and the power consumption (kWh) when the floor heating-air conditioner linked operation is performed, and A ′, Compared with B ′, the power consumption A at the time of start-up is 1.355 (kWh), for example, and the power consumption B during operation in a steady state is 4.868 (kWh). It is clear that there is an advantage that the temperature becomes a comfortable temperature in a short time.

  That is, although the floor heating consumes high power, the operation setting at a low temperature of the floor heating can be performed by operating the floor heating and the air conditioner 2 after the air conditioner 2 precedes. In addition, the air conditioner 2 continues to operate even after the operation of the floor heating device 1 is started. However, the air conditioner 2 automatically stops when the room temperature exceeds a certain level, and the air conditioner 2 automatically operates only when the room temperature decreases. The power consumption of the air conditioner 2 can be kept low. Moreover, by interlocking operation of the floor heating and the air conditioner 2, the room temperature and the floor temperature are set so that they are within the comfortable temperature range of the floor temperature and the comfortable temperature range of the room temperature shown in FIG. 2 (corresponding to the comfortable temperature range surrounded by hatching in FIG. 9). It becomes easy to control, and the problem of warm air during heating as in the case of single operation of the air conditioner 2 can be eliminated, and the problem of high operating costs as in the case of single operation of the floor heating can be solved at the same time. As a result, a more comfortable and more economical heating environment can be provided.

  Further, in this example, a plurality of infrared transmission units 4 can be added to one controller 3 that controls the floor heating device 1 according to the number of air conditioners 2 to be installed. In the example of FIG. 1, two infrared transmission units 4 are connected to one controller 3 by two electric wires 11, and the two air conditioners 2 operate independently. It is possible to easily cope with the expansion of the air conditioner 2 without increasing the number of units. In FIG. 1, 12 is a leakage breaker, 13 is a relay unit that connects the controller 3 and the floor heating device 1, and 14 is an additional relay unit that connects the added floor heating device 1 and the controller 3. Here, the number of the infrared transmission units 4 can be appropriately changed according to the number of the air conditioners 2 and may be one or three or more. The connection between the controller 3 and the infrared transmission unit 4 may be wireless instead of wired.

  In addition, when a plurality of air conditioners 2 are installed in one room as described above and an infrared transmission unit 4 is added for each air conditioner 2, one infrared signal S transmitted from the two infrared transmission units 4 is transmitted. If the air conditioner 2 receives the signals simultaneously, a malfunction may occur. That is, the infrared signal S interferes and the control device of the air conditioner 2 cannot receive correct data.

  Therefore, the infrared signal S is shifted and transmitted one by one so that one air conditioner 2 does not simultaneously receive the infrared signals S from the plurality of infrared transmission units 4. As a result, the infrared signal S from one infrared transmission unit 4 and the infrared signal S from the other infrared transmission unit 4 are not transmitted at the same time, but are transmitted at time intervals. Interference can be prevented, and malfunction of the air conditioner 2 can be reliably prevented.

  By the way, when installing the infrared transmission unit 4, there is a limit in restricting each installation position from the difference in the construction timing of the floor heating apparatus 1 and the air conditioner 2, for example. Even if the infrared transmission unit 4 is installed within the infrared light receiving range of the air conditioner 2, the positional relationship with the air conditioner 2 changes depending on the position of the wall surface on which the infrared transmission unit 4 is installed. In order to transmit an infrared signal over a wide range, it is necessary to be able to cover the installation direction of the infrared transmission unit 6 in all directions, and there is a problem that the number of LEDs 7 increases in order to increase the distance that the infrared signal can reach. is there. As shown in FIGS. 8A and 8B, even when the orientation of the plurality of LEDs 7 arranged in a vertical row is arranged radially in the vertical direction, the intensity of each LED 7 is dispersed. The transmission distance is shortened, the infrared light receiving range is limited to the shaded portion in FIG. 7, and it is difficult for the infrared signal to reach the portion other than the shaded portion. For this reason, when a long distance is required particularly in a large room, it is necessary to increase the number of LEDs 7 in each direction, and there is a problem that the cost and size of the infrared transmission unit 4 are increased.

  Therefore, in this example, in order to cover all directions, as shown in FIG. 3, the LEDs 7 a to 7 d in which the infrared transmission unit 6 is arranged in a vertical line with respect to the fixed frame 5 fixed to the wall surface of the room are arranged in the horizontal direction. It is supported by D so that it can rotate 180 °. Thereby, while being able to achieve size reduction of the infrared transmission part 6, since the infrared signal S can be spread and transmitted in all directions by rotation, it becomes more certain that all the LEDs 7a to 7d are directed to the air conditioner 2, The installation position of the air conditioner 2 is not restricted. Further, as shown in FIG. 3 (d), one LED 7a is disposed obliquely forward and upward C, so that the infrared transmission unit 4 is positioned lower than the air conditioner 2 (for example, the height difference H) as shown in FIG. = 0.5 m), when the distance from the air conditioner 2 is long (eg, d1 = 11 m, tilt angle α1 = 3 ° or more) or when the distance is short (eg, d2 = 1 m, tilt angle α2 = 25 ° or more) In any case, the LED 7a tilted diagonally forward and upward C can be directed to the air conditioner 2, and the infrared signal S can surely reach the air conditioner 2. Therefore, without increasing the number of LEDs 7a to 7d, the infrared light receiving range is expanded only by changing the direction of any one of the LEDs 7a to 7d.

  In the example of FIG. 3D, the LEDs 7a to 7d are arranged vertically in a line, and the three LEDs 7b to 7d other than the uppermost part are respectively arranged on the front front surface E. One LED 7d may be arranged obliquely forward and downward, thereby making it possible to make the lower range where the infrared signal S reaches a wider angle. For example, the infrared transmission unit 4 is more than the air conditioner 2. This is effective when installed at a high position. In addition, the arrangement direction of the LEDs 7a to 7d is not limited to one vertical row, and may be one horizontal row. In this case, at least one of the LEDs 7a to 7d may be arranged toward the diagonally upper front C.

  Further, in the example of FIG. 3, the outer shape 6 b of the infrared transmission unit 6 is formed in a circular or square shape in front view, and the shape of the attachment portion 5 a of the infrared transmission unit 6 in the fixed frame 5 is the infrared transmission unit with respect to the fixed frame 5. 6 is configured to be variable at an angle different by 90 ° in a front view. Accordingly, by selecting the attachment angle of the infrared transmission unit 6 with respect to the fixed frame 5, that is, by selecting the rotation axis of the infrared transmission unit 6 in either the vertical direction or the horizontal direction, the horizontal direction around the vertical axis It is possible to freely change between the rotation of D (FIG. 3A) and the vertical rotation around the horizontal axis (FIG. 3E), for example, an infrared transmission unit at a lower position (or higher position) than the air conditioner 2. 4 is installed, it is possible to direct all LEDs 7a to 7d to the upper (or lower) air conditioner 2 by changing the LEDs 7a to 7d from the rotation in the horizontal direction D to the vertical rotation. Become.

  As yet another example of the infrared transmission unit 6, as shown in FIG. 5, the infrared transmission unit 6 can be rotated by 90 ° in the left-right direction D at an angle θ3 of 180 °, and a predetermined angle within this rotatable range. It is desirable to have an elastic locking function of rotating so that locking is possible in increments of θ2, for example, 10 °. The structure of the elastic locking function is not particularly limited. Accordingly, portions other than the infrared light receiving range (shaded portions in FIG. 6) to which the infrared signals S from the respective LEDs 7a to 7d reach also become infrared light receivable ranges in which the infrared signals S reach. It is possible to direct all the LEDs 7a to 7d of the infrared transmitter 6 to the air conditioner 2 from any position even at any position (on the wall surface or floor). Moreover, since the LED 7a-7d can be rotated so that the angle of the LEDs 7a to 7d can be locked in increments of 10 ° by the elastic locking function, the direction of the infrared signal S can be adjusted in small increments, and the omnidirectional cover can be more reliably Can be. Of course, the rotation range of the infrared transmission unit 6 is not limited to 180 °, and can be rotated by 180 ° in the left-right direction D at an angle of 360 °. Further, it is possible to rotate so as to be able to be locked at an angle smaller than or larger than 10 °.
