Description

  The present invention relates to a controller used in an air conditioning system.

  Conventionally, a controller used in an air conditioning system includes a temperature sensor that detects a room temperature. When the controller determines that the detected temperature is abnormal, the controller displays an alarm on the display unit of the controller, assuming that the temperature sensor is abnormal. In the air conditioning system, an alarm is displayed on the controller, and the air conditioning control is switched to the air conditioning control based on the temperature detection by the temperature sensor of the air conditioner body. Such a technique is disclosed in Patent Document 1 below.

JP 2001-355893 A

  However, according to the above conventional technique, the controller may erroneously determine that the temperature sensor is abnormal when the temperature cannot be accurately detected due to the influence of a heat source such as solar radiation. In this case, in the air conditioning system, an alarm is displayed on the controller and air conditioning control is performed based on temperature detection by the temperature sensor of the air conditioner body. For this reason, there is a problem that information on the temperature sensor of the controller that can detect the room temperature around the user with high accuracy cannot be used for air conditioning control.

  This invention is made in view of the above, Comprising: When the temperature sensor of an own machine cannot detect indoor temperature correctly by the influence of a heat source, the controller which can eliminate the state which cannot detect indoor temperature correctly is obtained. For the purpose.

  In order to solve the above-described problems and achieve the object, the present invention is a controller that constitutes an air conditioning system together with an air conditioner, and includes temperature detection means for detecting a room temperature, and air conditioning performed by the air conditioner. An air conditioning setting unit that receives a desired set temperature from the user for operation, and a temperature determination that determines whether the temperature detection unit can normally detect the room temperature based on the room temperature and the set temperature And a display means for displaying an air conditioning control state by the air conditioner for a user, and when the temperature determination means determines that the temperature detection means has not normally detected the indoor temperature, Content for prompting the user to deal with is displayed on the display means.

  According to the present invention, when the temperature sensor of the own device cannot accurately detect the room temperature due to the influence of the heat source, it is possible to eliminate the state in which the room temperature cannot be accurately detected, and the user's periphery is air-conditioned according to the set temperature. There is an effect that it is possible.

  Embodiments of a controller according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
The air conditioning system according to the present embodiment includes an air conditioner and a controller. The controller may be a wired type fixed to a wall or a wireless type that can freely move. The wireless type includes high-functional terminals such as smartphones and tablets. In a duct-type air conditioning system such as a hotel, there is often no temperature sensor on the air conditioner side and a temperature sensor is mounted on the controller. Hereinafter, in the air conditioning system, a case where a temperature sensor is mounted on the controller will be described.

  FIG. 1 is a diagram illustrating a configuration example of a controller according to the present embodiment. The controller 10 includes a temperature detection unit 1, an air conditioning setting unit 2, a temperature determination unit 3, and a display unit 4. FIG. 2 is a diagram illustrating an appearance of the controller according to the present embodiment. On the external appearance of the controller 10, the display part of the display unit 4 is arranged so that it can be seen by the user.

  The temperature detection unit 1 is a temperature sensor that detects a room temperature mounted on the controller 10 and generally uses a thermistor. The thermistor (temperature detection unit 1) may be mounted on the electronic substrate of the controller 10, or is disposed outside the substrate in the controller 10 so that the measurement part of the thermistor (temperature detection unit 1) does not contact the substrate. It may be.

  The board mounted type thermistor (temperature detection unit 1) is lower in unit price than the lead type thermistor (temperature detection unit 1), and the mounting cost can be reduced. (Temperature detector 1) There is a characteristic that a change in the detected temperature is delayed. That is, at the start of the air conditioning operation, the room temperature changes greatly, and the room temperature may not be detected accurately. However, since the controller 10 is generally located in the vicinity of the user, the thermistor (temperature detection unit 1) can accurately detect the room temperature in the vicinity of the user except when the operation is started. Therefore, in an air conditioning system, it can control to the temperature which the user set by performing air-conditioning control based on the detected temperature which the temperature detection part 1 of the controller 10 detected.

  In the controller 10, the air conditioning setting unit 2 receives desired air conditioning settings from the user, such as the operation mode of the air conditioning system, the set temperature, the air volume, and the wind direction. The air-conditioning setting unit 2 may be a button or a touch panel, and the air-conditioning setting unit 2 may be one in which one button can change setting contents according to the state as well as one function operation. For example, in FIG. 2, a triangular up / down button below the display unit 4 is a temperature setting button in the cooling operation, but functions as an air volume setting button in the blowing operation.

  The temperature determination unit 3 estimates the indoor temperature based on the information on the detected temperature detected by the temperature detection unit 1 and the information on the set temperature set by the air conditioning setting unit 2, and the temperature detection unit 1 normally Determine whether the temperature is detected. When the temperature detection unit 1 determines that the room temperature has not been detected normally, the temperature determination unit 3 causes the display unit 4 to display content that prompts the user to move the controller 10.

  The display unit 4 normally displays the detected temperature (room temperature) detected by the temperature detection unit 1 and the set temperature set by the air conditioning setting unit 2, but in the temperature determination unit 3, the temperature detection unit 1 is normally in the room. When it is determined that the temperature has not been detected, the content of prompting the user to move the controller 10 is displayed under the control of the temperature determination unit 3. For example, as shown in FIG. 2, the display unit 4 displays a message “Please move the controller to a place where there is no influence of the heat source. The temperature cannot be measured accurately due to the influence of the airflow from the air conditioner.” .

  The display method in the display unit 4 may be either color or monochrome, or may be a liquid crystal that can be freely displayed or a segment that can only be fixedly displayed, and displays characters and illustrations.

  In addition, when using high function terminals, such as a smart phone and a tablet, as a controller, or when using a high function terminal as a display part of a controller, the high function terminal does not need to be equipped with the temperature detection part 1, and a temperature detection part The detected indoor temperature information may be communicated between the other configuration including 1 and the high-function terminal. As a system configuration, for example, a room temperature is detected in a configuration equipped with a temperature detection unit 1 having a wireless communication function, temperature information or display information detected from the configuration is transmitted to a high function terminal, and the temperature is detected in the high function terminal. There is a method for displaying information and the like, but the system configuration is not limited to this.

  Here, when the controller 10 is affected by time-varying solar radiation or a heat source such as a heating element such as a home appliance, the temperature detector 1 may not be able to detect the room temperature normally. In such a case, a description will be given of a method in which the controller 10 displays content that prompts the user to move the device.

  FIG. 3 is a diagram showing the temperature transition in the room by the air conditioning control of the air conditioning system. The horizontal axis represents time, and the vertical axis represents temperature. As an example, the detected temperature (room temperature), the set temperature, and the estimated temperature in the heating operation are represented.

  In the controller 10, based on the information on the air-conditioning mode and the set temperature set by the air-conditioning setting unit 2, the temperature determination unit 3 causes the current detected temperature (room temperature) to be the set temperature as a target in the heating operation as shown in FIG. It is estimated that the temperature rises with a simple curve (estimated temperature). Normally, in the air conditioning system, air-conditioning control is performed so that the detected temperature (room temperature) detected by the temperature detection unit 1 of the controller 10 reaches the set temperature, so the detected temperature (room temperature) is temporarily set. Even if the temperature is exceeded, the set temperature is not constantly exceeded.

  Therefore, the temperature determination unit 3 has a different slope from the inclination based on the estimated temperature, such as an inclination where the indoor temperature detected by the temperature detection unit 1 is steeper than the estimated temperature estimated by the operation control of the air conditioner based on the set temperature. When the temperature has changed, or when the detected temperature (room temperature) constantly exceeds the set temperature, the temperature detection unit 1 in the controller 10 may determine that the room temperature has not been normally detected due to the influence of the heat source. it can. When the temperature determination unit 3 determines that the temperature detection unit 1 cannot normally detect the room temperature due to the influence of the heat source, the controller 10 moves the controller 10 to a position where the influence of the heat source does not occur as shown in FIG. Display on the display unit 4 as shown.

  The display content shown in FIG. 2 is an example, and it is not essential to display the reason why the movement is necessary. However, by displaying the reason why the movement is necessary, the user should move the controller 10 for any reason. Can understand easily. In the controller 10, the content displayed by the temperature determination unit 3 on the display unit 4 is not limited to the content of countermeasures that prompt the movement of the controller 10. For example, the temperature determination unit 3 may display action advice that is not affected by a heat source such as closing a curtain on the display unit 4 as a countermeasure to the controller 10.

  Moreover, although the method of displaying the state of the controller 10 on the display unit 4 of the controller 10 has been described, the present invention is not limited to this, and the user is notified by the lighting pattern of the LED mounted on the air conditioner. It may be. In addition, by combining both the method of displaying on the display unit 4 of the controller 10 and the method of notifying with the lighting pattern of the LED mounted on the air conditioner, the user can more easily find out. Further, a sound may be generated so that the user can easily find it from a buzzer of the air conditioner body or a speaker (not shown) of the controller 10.

  Further, in the controller 10, the temperature determination unit 3 indicates that the user has implemented (behaves) the information displayed on the display unit 4 (for example, advice for urging movement of the controller 10 illustrated in FIG. 2). You may make it confirm by operation of a button, for example, a "Yes" button. The temperature determination unit 3 can reliably notify the user by maintaining the display of the display unit 4 until the action by the user is confirmed.

  Further, in the air conditioning system, if the user's action cannot be confirmed even after a long time has passed since the display on the display unit 4 of the controller 10, that is, if the state of the controller 10 is not improved, the air conditioning operation is forcibly stopped. May be. Furthermore, by continuing the display on the display unit 4 of the controller 10, it is possible to prompt the user to act.

  As described above, in the present embodiment, in the controller 10, when the temperature determination unit 3 determines that the temperature detection unit 1 cannot normally detect the room temperature due to the influence of the heat source, the controller 10 The display unit 4 displays the position so as to move. As a result, when the user moves the controller 10 to a position where the heat source does not influence, the state in which the room temperature cannot be accurately detected is eliminated, and the controller 10 can normally detect the room temperature around the user in the temperature detection unit 1. Then, based on the detected temperature detected by the temperature detection unit 1 of the controller 10, the user's surroundings can be air-conditioned according to the set temperature.

Embodiment 2. FIG.
In the present embodiment, when the temperature detection unit 1 determines that the room temperature cannot be normally detected due to the influence of the heat source, the air direction of the air conditioner is changed. A different part from Embodiment 1 is demonstrated.

  FIG. 4 is a diagram illustrating a configuration example of the controller according to the present embodiment. The controller 10 a includes a temperature detection unit 1, an air conditioning setting unit 2, a temperature determination unit 3 a, a display unit 4, and a wind direction control unit 5.

  When the temperature determination unit 3a determines that the room temperature cannot be normally detected due to the influence of the heat source in the temperature detection unit 1, the temperature determination unit 3a displays on the display unit 4 content prompting the user to move the controller 10, and the wind direction The control unit 5 is instructed to change the air direction of the air conditioner.

  The wind direction control part 5 changes the wind direction of an air conditioner based on the instruction | indication from the temperature determination part 3a.

  For example, when the air conditioning system is in the heating operation, the temperature determination unit 3a determines that the temperature detected by the temperature detection unit 1 changes with a steep slope from the estimated temperature, or the detected temperature is constantly set to the set temperature. Is exceeded, the temperature detection unit 1 in the controller 10a determines that the room temperature cannot be normally detected due to the influence of the heat source, but it is also predicted that the heating airflow of the air conditioner hits the controller 10a as the cause. . For this reason, the temperature determination unit 3a displays on the display unit 4 a display prompting the user to move the controller 10, and also prevents the heating airflow from hitting the controller 10a. Instruct to change the wind direction of the machine.

  FIG. 5 is a diagram illustrating the wind direction of the air conditioner. For example, when the air direction of the air conditioner is on the right side and the controller 10a is exposed to the heating airflow, the controller 10a changes the air direction of the air conditioner to the left side under the control of the temperature determination unit 3a and the wind direction control unit 5. Can be made. In the controller 10a, when the cause of the influence of the heat source is the heating airflow from the air conditioner, the influence of the heat source can be avoided.

  In addition, although the controller 10a demonstrated the case where the display part 4 displays simultaneously and the wind direction control part 5 performs the wind direction change of the air conditioner, it is not limited to this. For example, when the temperature determination unit 3a determines that the temperature detection unit 1 cannot normally detect the room temperature due to the influence of the heat source, the temperature determination unit 3a first instructs the wind direction control unit 5 to change the wind direction of the air conditioner. To do. And if the temperature determination part 3a is not improved even if the predetermined time passes after changing the wind direction in the air conditioner, that is, the temperature detection part 1 cannot detect the room temperature normally due to the influence of the heat source. When the state continues, a display that prompts the user to move the controller 10 may be displayed on the display unit 4.

  In the controller 10a, when the temperature determination unit 3a determines that the temperature detection unit 1 cannot normally detect the room temperature due to the influence of the heat source, the controller 10a controls the operation of the wind direction control unit 5 and the display unit 4. As described above, a configuration without the display unit 4 is also possible. For example, when the temperature determination unit 3a determines that the temperature detection unit 1 cannot normally detect the room temperature due to the influence of the heat source, the temperature determination unit 3a first instructs the wind direction control unit 5 to change the wind direction of the air conditioner. To do. And if the temperature determination part 3a is not improved even if the predetermined time passes after changing the wind direction in the air conditioner, that is, the temperature detection part 1 cannot detect the room temperature normally due to the influence of the heat source. When the state continues, a display prompting the user to move the controller 10 may be notified by a lighting pattern of the LED mounted on the air conditioner. Even in this case, the controller 10a can eliminate the state in which the room temperature cannot be accurately detected.

  As described above, in the present embodiment, in the controller 10a, when the temperature determination unit 3a determines that the temperature detection unit 1 cannot normally detect the room temperature due to the influence of the heat source, the controller 10a instructs the wind direction control unit 5. The air direction of the air conditioner was changed. Thereby, in addition to the effect of Embodiment 1, in the controller 10a, when the cause of the influence of a heat source is the heating airflow from an air conditioner, the influence of a heat source can be avoided by own control.

  As described above, the controller according to the present invention is useful for an air conditioning system, and is particularly suitable for an air conditioning system that detects an indoor temperature and performs air conditioning control.
