Background

Currently, most of the civil air conditioners are designed with an automatic mode which can automatically adjust the cooling capacity of the air conditioner according to the indoor temperature. The principle of the automatic mode is as follows: and detecting the temperature of a temperature sensing bulb on an internal unit of the air conditioner, and automatically adjusting the refrigerating capacity of the air conditioner according to the difference value of the temperature sensing bulb and the set temperature. However, as shown in fig. 1, the outlet air and the return air are closer, so the temperature around the air conditioner indoor unit body generally decreases faster than the overall indoor temperature, which causes the actual temperature around the human body in the room to be higher than the ideal value of the automatic mode design, resulting in a difference in the comfort of human body feeling compared with the ideal situation.

For this reason, the prior art proposes two solutions:

But the production cost is high, the installation difficulty is high, the maintenance is difficult, and the air conditioner is not suitable for household use.

2. The infrared image recognition and analysis function is designed in the air conditioner internal unit, but the research and development difficulty is high, the material cost of the control system is greatly increased, the maintenance cost is also high, and the use result is also easily influenced by other objects in the environment, such as hot food, high-temperature pets and the like.

Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 2.

The embodiment provides an intelligent remote controller, which comprises a shell 10 with a hollow interior, wherein the shell 10 comprises a display area 11, a key area 12 and a holding area 13.

The display area 11 may be installed with a display screen for displaying the set temperature of the air conditioner, the cooling and heating modes, and the like. The key area 12 is provided with keys, and parameters of the air conditioner, such as setting of temperature, cooling and heating modes, humidity and the like, can be set by operating the keys. When the key is operated, the user can hold the holding area 13 with a hand.

Further, a through hole 14 is opened in the housing 10. A thermopile infrared sensor 15 and a control circuit 16 connected to the thermopile infrared sensor 15 are provided in the case 10. The position of the thermopile infrared sensor 15 corresponds to the through hole 14, and is used for performing infrared temperature measurement through the through hole 14, as shown in fig. 2.

The control circuit 16 is used for sending an infrared control signal to control the refrigerating capacity of the air conditioner according to the temperature difference value between the environment temperature measured by the thermopile infrared sensor 15 and the set temperature.

Compared with the traditional thermistor, mercury and other materials, the thermopile infrared sensor 15 has higher measuring speed and can quickly and accurately identify and confirm the temperature of the human body.

Further, the thermopile infrared sensor 15 uses the seebeck effect, and the human body always radiates infrared rays due to the existence of the body temperature, so that the thermopile infrared sensor 15 can collect the infrared rays and convert the infrared rays into electric signals to output. Generally, there are two types of such sensors, which have an analog output and a digital output. The analog quantity output is used after comparing the output formula and calibrating, and the measurement result is output on the output pin in a level mode. The digital output is that the calculation of the temperature value is completed in the sensor, and then the digital output is output in the mode of I2C or PWM, and the control circuit 16 containing the MCU can obtain the accurate value only by communication.

Specifically, the thermopile infrared sensor 15 may communicate temperature identification information in the manner of I2C, as shown in the schematic diagram of fig. 3.

In order to better detect the temperature of the human body heat source, the peripheral part of the through hole 14 is made of transparent material, for example, the holding area 13 is made of transparent material.

In the present embodiment, the housing 10 has a rectangular parallelepiped shape as a whole, and the through hole 14 may be a circular hole.

The working principle of the embodiment is as follows:

because the remote controller is generally placed at a place close to a human body in the using process, the ambient temperature around the remote controller can represent the actual human body sensed temperature, and when the ambient temperature measured by the thermopile infrared sensor 15 is higher than the set temperature, an infrared control signal can be sent to the air conditioner to improve the refrigerating capacity of the air conditioner. Specifically, the way of the air conditioner to increase the cooling capacity includes: the fixed-frequency type reduces the shutdown time, the frequency converter type improves the frequency of the compressor and improves the rotating speed of the fan. On the contrary, when the ambient temperature measured by the thermopile infrared sensor 15 is less than the set temperature, an infrared control signal can be sent to the air conditioner to reduce the refrigerating capacity of the air conditioner. Specifically, the way that the air conditioner reduces the cooling capacity includes: the fixed frequency type increases the shutdown time, and the frequency converter type reduces the frequency of the compressor and reduces the rotating speed of the fan.

According to the intelligent remote controller provided by the embodiment, manual operation is not needed, and the air conditioner can automatically control the refrigerating capacity according to the infrared control signal sent by the intelligent remote controller; the air conditioner does not need to be redesigned, and only the remote controller is upgraded, so that the cost is low; the system does not depend on complex wireless modules such as wifi or Bluetooth and the like, so that the upgrading cost is low; the technical scheme can be applied to almost all air conditioners using the remote controller.

Thus, the example term "below … …" can encompass both an orientation of facing upward and downward. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted.

The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
