Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a wall-mounted digital thermohygrometer, and particularly to a wall-mounted digital thermohygrometer suitable for use in a temperature/humidity adjustment device.

"Conventional technology" Conventionally, for example, in the case of heating control using a boiler, only the temperature sensor and humidity sensor were installed on the wall of the room to be controlled, and the temperature sensor and humidity sensor were installed on the wall of the room to be controlled. The detection signal from the humidity sensor is guided by cable to a temperature/humidity adjustment device in a monitoring room (boiler) installed in a separate location, and the temperature/humidity adjustment device controls the boiler using the detection signals from the temperature sensor and humidity sensor. .

However, since the room only has a temperature sensor and a humidity sensor, in order to recognize the actual room temperature and humidity values, it is necessary to go to the boiler room each time and check the detection from the temperature sensor and humidity sensor. The content displayed on the display device had to be viewed according to the signal, which was extremely cumbersome. In order to know the temperature and humidity in a room, it is necessary to install a separate thermometer and hygrometer, and the measured values from the separately installed thermometer and hygrometer and the measured values from the above temperature sensor and humidity sensor. In addition to the occurrence of errors due to this, there were also problems with the increase in the number of parts.

``Problems to be solved by the invention'' In view of the above circumstances, the present invention not only makes it possible to know the temperature and humidity in a room, but also adjusts the temperature and humidity adjustment device of the boiler based on the measured values of temperature and humidity. Furthermore, not only the sensors that detect temperature and humidity, but also the electronic circuits such as the power supply circuit and output circuit, and the display section are all integrated, making it easy to install and handle. It is an object of the present invention to provide a wall-mounted digital thermohygrometer that can simplify the configuration by being able to share a ventilation fan for cooling the electronic circuit and a cooling fan for cooling the electronic circuit.

"Means to be Solved by the Invention" In order to achieve the above object, the present invention has an opening on the circumference of the case, partitions the inside of the case with partition walls, and installs a temperature sensor and a humidity sensor in one partition. The sensor is stored in the other partition, and electronic circuits such as power supply circuits, detection circuits, output circuits for other devices, and temperature and humidity display devices are stored in the other partition, and the case straddles both partitions. It features a wall-mounted digital thermohygrometer equipped with a ventilation fan.

“Example” An example of the wall-mounted digital thermohygrometer according to the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a case. The case 1 consists of a base case 1a and a lid case 1b, each having a peripheral wall. The lid case 1b has tongue pieces 2 and 3 extending from the upper and lower portions of both side walls, and screw holes are provided at corresponding positions of the tongue pieces 2 and 3 and both side walls of the base case 1a. By screwing screws 4 and 5, the lid case 1b is attached to the base case 1a. Lid case 1b to base case 1a
In the attached state, openings 6 are formed on both the upper and lower surfaces and on both the left and right sides. The interior of the base case 1a is divided into left and right partitions 8 and 9 by a partition wall 7, as shown in FIGS. 1 and 2. As shown in FIGS. A temperature sensor 11 and a humidity sensor 12 are attached to one of the partitions 8 with a heat insulating material 10 interposed therebetween. The other partition 9 contains a power supply circuit, a detection circuit,
and various electronic circuits 13 such as output circuits to other devices
will be housed. The power supply circuit receives commercial power and supplies power to the detection circuit and output circuit. The detection circuit includes the temperature sensor 11 and the humidity sensor 1.
Upon receiving the detection signal from 2, the detection signal is processed so that it can be provided to an output circuit and the temperature and humidity can be displayed on a display device 14, which will be described later. The output circuit is for receiving a detection signal from the detection circuit and outputting it as a controlled signal to the boiler temperature and humidity adjustment device via a connector 15, which will be described later. On the other hand, a heat insulating material 10 is laid at a position corresponding to the partition chamber 8 on the inner surface of the lid case 1b. Further, a display device 14 is attached at a position corresponding to the partition chamber 9 on the inner surface of the lid case 1b. The display device 14 includes a temperature display section 14a that displays the temperature in the room by providing a signal from the electronic circuit 13, and a humidity display section 14b that displays the humidity in the room. The temperature display section 14a and the humidity display section 14b are
Measured values are now displayed digitally using light emitting diodes and Nixie tubes. In addition to the connector 15, the lid case 1b also includes a main switch 16 for turning on and off the power supply circuit, and a switch 1 for turning on and off a ventilation fan 17, which will be described later.
8 is attached. Additionally, a small printer 19 is attached to the lid case 1b to print out temperature and humidity information at regular intervals. The printer 19 does not necessarily have to be attached, but can be attached as desired, and it can also be detachably attached to one side of the case 1, as shown by the two-dot chain line in FIG. It is possible. The ventilation fan 17 is fitted and fixed between the upper wall of the base case 1a and the upper end of the partition wall 7. Further, the ventilation fan 17 is arranged so as to draw in air from both the partitions 8 and 9 and exhaust it upward.

That is, the ventilation fan 17 is used to constantly draw air from the room into one of the partitions 8 through the opening 6 and measure the temperature and humidity inside the room using the temperature sensor 11 and the humidity sensor 12. This prevents air from accumulating in the chamber 8 and causing erroneous measurements or measurements with large errors due to the accumulated air. Further, the ventilation fan is designed to take air from the room into the partition 9 through the opening 6 to cool the electronic circuit 13. The air in each of the partitions 8 and 9 is discharged upward from the top opening 6 of the case 1 by a ventilation fan 17. The heat insulating material 10 blocks the amount of heat generated by the electronic circuit 13, particularly the power supply circuit, from being transmitted to the temperature sensor 11 and the humidity sensor 12 via the base case 1a and further through the lid case 1b. The partition wall 7 also prevents the amount of heat in one partition 9 from being directly transmitted to the other partition 8.

"Effect of the invention" As described above, according to the wall-mounted digital thermohygrometer according to the invention, the temperature sensor, the humidity sensor, and the display device are integrated, so it is possible to visually check the temperature and humidity in the room. Not only can it be used, but it is extremely easy to install, maintain, and manage, and the ventilation fan for measuring temperature and humidity and the cooling fan for cooling the electronic circuit can be shared.
It is possible to reduce the number of parts and simplify the configuration. Furthermore, the temperature and humidity adjusting device of the boiler can be controlled by the detection signals from the temperature sensor and the humidity sensor, making it extremely convenient to use because one device can perform several functions.
