Abstract

The present invention provides a drain pipe anti-freezing heater which improves the conventional drain pipe heater and has the same electric power and an internal temperature of at least twice, thereby improving the anti-freezing ability. A drain tube freeze prevention heater according to the present invention includes an annular space-like heater storage portion surrounded by a PVC short cylinder 1, a stainless cover 2, and a stainless outer cylinder 3. A heat shield 4 is mounted along the inside of the stainless outer cylinder 3 so that heat does not escape to the outside, and a self-temperature-controlling heater 5 for heating is placed inside the heat shield 4. It is provided along. Further, an annular notch is formed inside the heater housing portion of the PVC short cylinder 2 and is closed by the PVC inner cylinder 6, and a far-infrared sheet 7 is placed inside the heater housing portion of the PVC inner cylinder 6.

  An object of the present invention is to improve the drain pipe heater, and to provide a drain pipe anti-freezing heater that has the same electric power and an internal temperature that is more than doubled to improve the anti-freezing ability.

  The drain pipe anti-freezing heater of the present invention includes a cylindrical PVC short cylinder that serves as a drain pipe for discharging rainwater, and a short cone that extends conically from the upper and lower ends of the PVC short cylinder to the outside of the PVC short cylinder. A stainless steel cover having a conical cylinder, a cylindrical stainless outer cylinder connecting upper and lower short conical cylinders of the stainless steel cover, and an annular space heater surrounded by the polyvinyl chloride short cylinder, the stainless cover and the stainless outer cylinder A heat shielding material is mounted along the inner side of the stainless steel outer cylinder so that heat does not escape to the outside of the stainless steel outer cylinder side, and the inner side of the heat shielding material. A self-temperature-control heater for heating is provided along the heat shield, and an annular notch is formed on the inner side of the heater storage portion of the PVC short cylinder to form a PVC inner circle. Closing in, in the heater housing portion inner salt bi inner cylinder is to adhere the far infrared sheet.

The drain pipe anti-freezing heater of the present invention includes a cylindrical PVC short cylinder that serves as a drain pipe for discharging rainwater, and a short cone that extends conically from the upper and lower ends of the PVC short cylinder to the outside of the PVC short cylinder. A stainless steel cover having a conical cylinder, a cylindrical stainless outer cylinder connecting upper and lower short conical cylinders of the stainless steel cover, and an annular space heater surrounded by the polyvinyl chloride short cylinder, the stainless cover and the stainless outer cylinder A heat shielding material is mounted along the inner side of the stainless steel outer cylinder so that heat does not escape to the outside of the stainless steel outer cylinder side, and the inner side of the heat shielding material. In addition, since the heating self-temperature control type heater is provided along the heat shielding material, there is an effect that the internal temperature can be doubled or more with the same electric power.
The drain pipe freeze prevention heater according to the present invention further includes an annular cutout formed inside the heater housing portion of the PVC short cylinder, which is closed by the PVC inner cylinder, and inside the heater housing portion of the PVC inner cylinder. Since a far-infrared sheet is pasted on, the effect of freezing prevention can be improved by the far-infrared effect.
The drain freeze prevention heater of the present invention has an effect of increasing the strength because the outside is changed to stainless steel instead of the conventional PVC type.

It is a longitudinal cross-sectional view of the drain pipe freezing prevention heater of this invention. It is a top view of the drain pipe freezing prevention heater of this invention.

One embodiment of the drain pipe freeze prevention heater of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the drain pipe freezing prevention heater of the present invention includes a cylindrical PVC short cylinder 1 serving as a drain pipe for discharging rainwater, and the PVC short pipe 1 from the upper and lower ends of the PVC short cylinder 1. A stainless steel cover 2 having a short conical cylinder extending outside the cylinder 1 in a conical shape, a cylindrical stainless outer cylinder 3 connecting the upper and lower short conical cylinders of the stainless steel cover 2, and the PVC short cylinder 1 and the stainless steel cover 2 and a stainless steel outer cylinder 3 surrounded by an annular space heater housing.
The heater housing is provided with a heat shield 4 along the inside of the stainless steel outer cylinder 3 so that heat does not escape to the outside of the stainless steel outer cylinder 3 side. The self-temperature control type heater 5 is provided along the heat shield 4.
Further, an annular notch is formed inside the heater housing portion of the PVC short cylinder 1 and is closed by the PVC inner cylinder 6, and a far infrared sheet 7 is placed inside the heater housing portion of the PVC inner cylinder 6. Adhere.
Number 8 is Negros.

Next, the operation of the drain pipe freeze prevention heater according to the present invention will be described below with reference to the drawings.
The drain pipe freezing prevention heater of the present invention is connected to the drain outlet of the drain pipe that discharges rainwater from the roof or roof of a high-rise building such as a building, and the electrical cord is plugged into an outlet (not shown) The temperature-controlled heater 5 is energized.
When the outside air temperature falls, the temperature of the self-temperature control type heater 5 shown in FIG. 1 rises, and since the heat shield 4 is applied to the outside air side of the heater housing, the space in the heater housing is efficiently heated. In order to warm the far-infrared sheet 7 inside the heater housing, the far-infrared sheet 7 emits far-infrared rays and efficiently warms the PVC short cylinder 1, so that the warm air rises in the drain pipe.
The outside air that has entered from the drain outlet is warmed and raised by the drain pipe anti-freezing heater, and the warm air is exhausted from the roof and the roof outlet while preventing freezing of the vertical drain pipe. Prevents freezing.
Moreover, the snowmelt water flowing down the vertical drain pipe flows down without freezing because the entire drain pipe is warmed by the drain pipe freezing prevention heater.
