FIG. 2 is an explanatory view showing an example of the configuration of the forced draft tube type thermometer. FIG. 3 is an explanatory diagram showing an example of the operation of the forced ventilated tubular thermometer.

  The forced draft cylinder type thermometer 1 according to the present invention is for measuring the temperature, and in particular, it is intended to accurately measure the temperature in a place where it is difficult to measure the temperature, such as in an agricultural vinyl house. It is what. The forced draft cylinder thermometer 1 includes a draft module 10, an external heat insulating part 20, an electric module 32 and the like.

  The ventilation module 10 includes a cylindrical ventilation tube 12 made of a paper tube, a temperature sensor 18 provided in the ventilation tube 12, and a fan 16 provided in the upper end opening 12 c of the ventilation tube 12. The temperature sensor 18 is connected to an electric module 32 described later, and transmits the temperature of the inside 12 b of the ventilation pipe 12 to the electric module 32. In addition, in this application, the temperature sensor 18 shall call the temperature sensor 18 widely what can measure humidity other than what only measures temperature. The fan 16 is an electric type and rotates upon receiving power from the electric module 32. The fan 16 operates to suck up the air in the interior 12 b of the ventilation pipe 12 and eject the air from the upper end opening 12 c of the ventilation pipe 12.

  The external heat insulating portion 20 is made of a heat insulating material 22 that covers the outer periphery of the ventilation pipe 12 with a predetermined interval. That is, the external heat insulating part 20 is a cylindrical heat insulating material 22 having a predetermined thickness, and can accommodate the ventilation pipe 12 in the internal 20b. There is a gap S between the external heat insulating part 20 and the ventilation pipe 12, but the external heat insulating part 20 below the external heat insulating part 20 so that the ventilation pipe 12 does not move unnecessarily in the inside 20 b of the external heat insulating part 20. A spacer 26 is provided between the inside 20 b of the air pipe and the outer periphery of the ventilation pipe 12.

  The heat insulating material 22 of the external heat insulating section 20 may be made of a material that can block heat that affects the measurement of the air temperature that is originally desired to be measured, such as solar heat at the place where the forced ventilation tube thermometer 1 is installed. Although it can be used, a foamed urethane resin is particularly desirable. Specifically, the heat insulating material 22 of the external heat insulating portion 20 is preferably a foamed urethane pipe because it is easy to use. Furthermore, in order to reduce the influence of solar radiation that affects the measurement of the air temperature that is originally desired to be measured, such as solar heat at the place where the forced draft tube thermometer 1 is installed, the outer periphery of the external heat insulating portion 20 is made of a highly reflective material 24. It is effective to cover. As this highly reflective material 24, an aluminum stay is particularly preferable.

  The electric module 32 includes an electric circuit for driving the fan 16 and collecting information of the temperature sensor 18, and power is supplied from, for example, an AC power adapter 36. The electrical module 32 accumulates information on the temperature and humidity measured by the temperature sensor 18 and retrieves the information as needed, or connects to an external electronic device by wire or wirelessly and retrieves the information as appropriate or as needed. There is a method of providing transmission means. As a wireless transmission means, for example, there is an IEEE 802.11 method, etc., and by making it wireless, the degree of freedom increases in the connection between the forced draft tube thermometer 1 and an external device, and the temperature measurement place is It becomes easy to decide arbitrarily.

  The electric module 32 is accommodated in the upper cover 30 that covers the upper end opening 20 c of the external heat insulating portion 20 and the upper end 22 a of the heat insulating material 22. The upper cover 30 is provided with a hook 34 for installing the forced ventilated tubular thermometer 1 at the upper part, and a blower outlet 30a for letting the air that has passed through the ventilating pipe 12 out on the side surface. It has been drilled.

  The ventilation module 10 is detachable from the entire forced ventilation cylinder thermometer 1. When the paper tube ventilation pipe 12 of the ventilation module 10 is damaged, the ventilation module 10 is replaced. It has a structure that can be done. The material of the ventilation pipe 12 is preferably a paper pipe from the viewpoint of cost, ease of processing, etc., but is not limited to the paper pipe, and an inexpensive PVC pipe or the like can also be used.

  As a more specific structure, a plate-like saddle member 14 protruding in the outer peripheral direction is provided around the upper end opening 12c of the ventilation pipe 12, and the ventilation module 10 is inserted into the inside 20b of the external heat insulating portion 20, The ventilation module 10 is arranged in the above-described predetermined positional relationship with the external heat insulating part 20 in a state in which the brazing material 14 is in contact with the upper end 22a of the heat insulating material 22 of the external heat insulating part 20. Then, the wiring of the fan 16 and the temperature sensor 18 of the ventilation module 10 may be connected to the electric module 32 so that the upper cover 30 is placed over the external heat insulating portion 20. On the contrary, when the ventilation module 10 is removed from the forced ventilation cylinder thermometer 1, the upper cover 30 is removed from the external heat insulating portion 20, and wiring is removed between the electric module 32 and the fan 16 and the temperature sensor 18. Thereafter, the ventilation module 10 may be extracted from the external heat insulating portion 20.

  The operation of the forced draft cylinder thermometer 1 having the above-described structure is as follows. The forced draft cylinder thermometer 1 is disposed in a place where it is desired to measure the temperature in an agricultural vinyl house or the like. Turn on the power. Then, when the fan 16 rotates, air is sucked from the lower end opening 12a of the ventilation pipe 12 of the ventilation module 10, and the air sucked into the ventilation pipe 12 passes through the inside 12b of the ventilation pipe 12 where the temperature sensor 18 is located. Then, it exits from the upper end opening 12 c of the ventilation pipe 12 and exits from the outlet 30 a of the upper cover 30 to the outside of the forced ventilation tubular thermometer 1. Meanwhile, the temperature sensor 18 measures the temperature and humidity of the air passing through the inside 12 b of the ventilation pipe 12, sends the information to the electric module 32, and the electric module 32 sends the information to the outside of the forced draft cylinder thermometer 1. It will be.

  According to the forced ventilation cylinder thermometer 1 having the above structure and operation, a paper tube is used for the ventilation pipe 12 of the ventilation module 10 or a foamed urethane resin is used as the heat insulating material 22 while simplifying the structure. Thus, the cost can be suppressed. Further, by using a paper tube for the ventilation tube 12 or using a urethane foam resin as the heat insulating material 22, the weight can be reduced as compared with that made of metal, and no special construction for installation is required. Further, a urethane foam resin is used for the heat insulating material 22 of the external heat insulating portion 20, a highly reflective material 24 is disposed on the outer periphery of the external heat insulating portion 20, or a gap S is provided between the external heat insulating portion 20 and the ventilation pipe 12. Therefore, it is possible to cut off the heat that affects the measurement of the air temperature that you want to measure, such as solar heat, where the forced ventilated thermometer 1 is installed, enabling more accurate temperature and humidity measurements. Yes.

  Further, the cost can be reduced by using a paper tube, an inexpensive PVC tube or the like for the ventilation tube 12 of the ventilation module 10. On the other hand, the ventilation module 10 itself is likely to deteriorate if it is made of paper tube, but it deteriorates by making the ventilation module 10 detachable from the forced ventilation cylinder thermometer 1 and allowing the ventilation module 10 to be replaced with a new one. It solves easy problems.

  Furthermore, as shown in FIG. 3, the ridge material 14 of the ventilation module 10 is between the upper end opening 12 c of the ventilation tube 12 and the upper end opening 20 c of the external heat insulating part 20 and passes through the ventilation tube 12 of the ventilation module 10. By functioning as a partition wall that prevents air from flowing between the external heat insulating portion 20 and the ventilation pipe 12, more accurate measurement of temperature and humidity becomes possible.

  The electric module 32 is housed in the upper cover 30 that covers the upper end opening 20c of the external heat insulating portion 20 and the upper end 22a of the heat insulating material 22. The electric module 32 is positioned at the fan 16 of the ventilation module 10. In this position, since the wind of the fan 16 directly hits the electric module 32 and there is a concern about condensation, the lower part of the electric module 32 is covered and protected by a protective cover 30b.

  As described above, according to the present invention, it is possible to provide a forced draft cylinder thermometer capable of suppressing the cost while simplifying the structure and capable of accurately measuring the temperature.
