Hereinafter, the state of use of the energy-saving warming and shading device 1 of the greenhouse according to the present invention will be described in detail.

First, when the electric motor 40 is driven in a forward direction in a state in which the sunshade film 60 is wound around the first winding roll 50 inside the case 100, the pull wire 80 is driven in a forward direction, It is preferable that the pulling wire 60 moves forward in the longitudinal direction of the holding member 10 and in the transverse direction of the horizontal support member 20 . Accordingly, the sunshade film 60 connected to the pulling wire 80 may be unfolded.

It may be arranged to be moved in a simple cloud along the front and rear directions of the pull wire 80.

In addition, as the electric motor 40 rotates forward in a state in which the pull wire 80 is released, the sunshade film 60 is spread and tension is applied, and the winding length of the pull wire 80 is second wound When the detection means 82 for detecting the number of rotations of the roll 70 detects a load value of the number of rotations set in advance, forward driving of the electric motor 40 may be automatically stopped.

Therefore, unlike the prior art in which the driving of the motor that spreads the sunshade in contact with the limit switch disposed on the front frame is stopped, the length of the winding wire 80 is set to the rotation speed load value of the second winding roll 70. When the load generated by the electric motor 40 exceeds a predetermined number of revolutions, the forward driving of the electric motor 40 is provided with a non-contact structure in which control is stopped. Accordingly, since the user can adjust the unfolded length of the sunshade 60 by a preset value, convenience of use can be improved.

When the sunshade 60 is wound, it is stored in the case 100 to prevent damage caused by sunlight, so that the durability of the product can be improved. In addition, since the sunshade film 60 is located at the lower end of the holding member 10, it is possible to prevent the occurrence of shade by eliminating the occlusion phenomenon caused by sunlight.

Next, when the electric motor 30 is driven in the forward direction while the sunshade film 60 is unfolded by the pulling wire 80, the sunshade film 60 is wound around the first winding roll 50. At the same time, the electric motor 40 is driven interlocked in the reverse direction to release the pull wire 80 wound around the second winding roll 70 .

As described above, the energy-saving warming and shading device of the greenhouse according to the present invention is economical by simplifying the assembly structure by making the installation position of the case 100 for storing the shading film 60 on the floor, and facilitating assembly and disassembly, so that the shading film ( 60) can be conveniently replaced or cleaned, and parts can be replaced and repaired quickly when the device fails, so it is a useful invention that can increase the efficiency of use of the device.
