Description

Technical Field

[0001] The invention relates to the field of sun exposure of the outer wall of a room in a residential unit building in life, and in particular to a room indoor cooling device. Background Art

[0002] In residential unit buildings, when the east and west exterior walls are exposed to the sun, the air temperature in the residential room rises. When the owner opens the door, a section of hot air dissipates from the room. When the owner enters the room, it is like entering a sauna. The hot air is very uncomfortable in the room for a while. The reason for the high air temperature in the room is that the air in the room does not produce convection with the outside air, and a lot of heat accumulates in the room and cannot be dissipated. Summary of the invention

[0003] The purpose of the present invention is to provide a room indoor cooling device, which has the advantage of effectively preventing the air temperature in the room from rising. It uses solar energy to generate electricity and cool down, which solves the problem that the owner can enter the room naturally without worrying about the hot air in the room, and the owner can enter the room to rest naturally.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a room indoor cooling device, comprising a solar panel, an exhaust fan, a solar controller, a solar battery, a wire, a switch, a variable cross-section pipe fitting, an exhaust hose, a check valve, and a PVC pipe; characterized in that: the solar panel is installed on the aluminum alloy window glass in the room or on the outer wall of the balcony, generates electricity under the irradiation of sunlight, and the solar panel is connected with a wire to store electricity into the solar battery; the exhaust fan, the solar battery, and the switch are connected with a wire to form a closed circuit, and the exhaust fan is driven by automatic start-up and manual start-up by a thermostat; the exhaust fan is installed on the inner wall of the room, the solar panel is installed on the aluminum alloy window glass in the room or on the outer wall of the balcony where the sun is shining, the solar controller and the solar battery are installed on the support plate, the support plate is installed on the inner wall of the room, and the solar panel and One end of the wire is connected, and the other end of the wire is connected to the solar controller. The solar controller and the solar battery are connected with a wire. The positive pole of the solar panel, the solar controller and the solar battery are connected to the positive pole, and the negative pole of the solar panel, the solar controller and the solar battery are connected to the negative pole. The exhaust fan, the solar battery and the switch are connected with a wire; the exhaust outlet pipe of the exhaust fan is connected to one end of the cross-section pipe fitting, and the other end of the variable cross-section pipe fitting is connected to the exhaust hose, the other end of the exhaust hose is connected to the check valve, and the other end of the check valve is connected to the PVC pipe. The PVC pipe is passed through the hole in the outer wall to exhaust outside. The outer wall of the PVC pipe and the wall are sealed with glue to prevent rainwater from seeping along the pipe wall. The PVC pipe has a slope greater than 1.5% tilted downward toward the outer wall. The switch is turned on, the exhaust fan starts, and the check valve is affected by the air pressure and opens upward. When there is no exhaust, it falls down and closes.

[0005] Furthermore, solar panels are installed on aluminum alloy window glass, generate electricity when exposed to sunlight, and store electricity in solar batteries. Solar panels include fixed panels, vertically folding solar panels, and horizontally folding solar panels. Solar panels are installed on the sunlit exterior wall of the balcony, which does not affect the lighting of the room through the window. The area of ​​the solar panels can be increased, and solar batteries with large storage capacity are used. The power of the exhaust fan is increased, the room is cooled faster, and the indoor hot air is pumped outdoors. The solar panel generates direct current, and the exhaust fan model is alternating current. Then, an inverter is connected between the solar battery and the exhaust fan with alternating current by wires. Direct current is converted into alternating current, which then drives the exhaust fan to rotate. The switch includes ordinary switch A, ordinary switch B and thermostat element. Ordinary switch A is connected to the remote control, which can start ordinary switch A on or off at a scheduled time. Ordinary switch B is connected in series with the thermostat element, and ordinary switch A is connected in parallel with ordinary switch B and the thermostat element. When the air temperature in the room reaches the set temperature, the thermostat element is connected to the wire and the exhaust fan starts. When the air temperature in the room is lower than the set temperature, the wire is not connected and the exhaust fan stops. For example, if the thermostat element is connected at 35 degrees, the exhaust fan starts when the air temperature in the room is 35 degrees, otherwise the exhaust fan stops.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The present invention discloses a room indoor cooling device. When a residential unit building is exposed to the sun and the east and west exterior walls are irradiated by sunlight, the indoor temperature of the room is very high. After the cooling device is installed, when the owner opens the door, the blades of the exhaust fan rotate to draw the air in the room to the outside, reducing the amount of hot air in the room. The owner can enter the room to rest and feel very comfortable. BRIEF DESCRIPTION OF THE DRAWINGS
