Embodiment 1

[0045] Such as figure 1 As shown, this embodiment provides an outdoor temperature detection device for a heating furnace, including a smoke pipe 1, and the smoke pipe 1 includes an air intake pipe 11, and the inner wall of the air intake pipe 11 is equipped with a device for collecting the air in the air intake pipe 11 before and after the operation of the fan. The temperature sensor 2 is electrically connected to the heating furnace controller 3 .

[0046] Specifically, the smoke pipe 1 is a balanced smoke pipe, the outer pipe of the balanced smoke pipe is the intake pipe 11, the inner pipe is the exhaust pipe 12, the intake pipe 11 is set on the outside of the exhaust pipe 12 to form a coaxial pipe, and the balanced smoke pipe One end of one end is connected with the fan, and the temperature sensor 2 is installed on the inner wall of the air intake pipe 11 of the outer layer, and placed at the junction of the balance smoke pipe and the fan.

[0047] In this embodiment, the ...

Embodiment 2

[0073] This embodiment provides an outdoor temperature detection device for a heating furnace, which includes a smoke pipe 1, the smoke pipe 1 includes an air intake pipe 11, and a temperature sensor 2 is installed on the inner wall of the air intake pipe 11, and the temperature sensor 2 is electrically connected to the heating furnace controller 3. connect.

[0074] Specifically, such as Figure 5 As shown, the smoke pipe 1 is a separate smoke pipe. The separate smoke pipe includes an air intake pipe 11 and an exhaust pipe 12 arranged separately. The temperature sensor 2 is installed at the connection between the air intake pipe 11 and the heating furnace body. The temperature value of the gas in the intake pipe 11 detected by the temperature sensor 2 is not affected by the temperature of the gas in the exhaust pipe 12 . In this manner, the temperature sensor 2 has high accuracy in detecting the outdoor temperature, and no temperature compensation is required.

Abstract

The invention relates to the technical field of heating furnaces, and discloses an outdoor temperature detection device for a heating furnace, an automatic temperature control method and a heating furnace. According to the outdoor temperature detection device for the heating furnace, a temperature sensor detecting the outdoor temperature is installed on the pipe wall of the inner side of an air inlet pipe, the problem of additional drilling is solved, the installation cost is lowered, the problem that the reliability of temperature collection of the temperature sensor is affected by outdoor factors is further effectively solved, and the collection accuracy of the temperature sensor is improved. The automatic temperature control method is applied to the outdoor temperature detection device,and the temperature compensation accuracy is high. The heating furnace can adjust the water supply temperature according to an outdoor temperature value in real time, and energy consumption of the heating furnace is reduced to achieve the purposes of energy conservation and environmental protection. The heating furnace adopts the automatic temperature control method, use is convenient, the energyconsumption is reduced, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of heating furnaces, in particular to an outdoor temperature detection device of a heating furnace, an automatic temperature control method and a heating furnace. Background technique [0002] The heating furnace is a high energy-consuming product, and users are very concerned about the energy consumption of the heating furnace. In the prior art, the heating furnaces on the market generally use temperature compensation technology to reduce the energy consumption of the heating furnace. The heating furnace with temperature compensation function installs a temperature sensor outdoors, and the temperature sensor collects the outdoor temperature to achieve temperature compensation. Adjust the water supply temperature of the heating furnace in real time. Installing a temperature sensor outdoors generally requires drilling holes on the wall or on the smoke pipe. The drilling needs to be done by the customer, whic...
