Description

Technical Field

[0001] This application relates to the technical field of green, energy-saving and environmentally friendly buildings, and in particular to an energy-saving house. Background Technology

[0002] Solar energy is a renewable energy source. It refers to the sun's thermal radiation energy, mainly manifested as sunlight. It is generally used for power generation or to provide energy for water heaters, and is now widely used in energy-efficient homes.

[0003] Typically, energy-efficient homes have solar panels installed on the roof to utilize solar energy. The solar panels can convert solar energy into heat energy, which is then transferred to water to raise the water temperature. The hot water is then supplied to the taps and heating equipment inside the house for people to wash, do laundry, and keep warm. The solar panels can also convert solar energy into electricity to power the home appliances.

[0004] However, while solar panels absorb solar energy, they also raise the roof temperature of energy-efficient houses. In cold weather, the indoor temperature will become warmer due to the increased roof temperature; while in hot weather, the indoor temperature will also rise due to the increased roof temperature, thereby increasing the frequency and duration of use of cooling appliances (such as air conditioners and fans). In this case, solar panels not only fail to achieve the effect of energy saving, but also cause more energy to be consumed. Summary of the Invention

[0005] In order to improve the problem that energy-efficient houses are not effective in high-temperature weather, this application provides an energy-efficient house.

[0006] This application provides an energy-efficient house, which adopts the following technical solution:

[0007] An energy-saving house includes a roof structure and several solar panels. The roof structure has an internal cavity. The solar panels are located on the top of the roof structure and above it. A water storage tank is provided on the top of the roof structure, located inside the top of the roof structure, and the water storage tank stores water. Several ventilation holes and several connecting holes are also provided inside the top of the roof structure. One end of each ventilation hole communicates with the cavity, and the other end of each ventilation hole communicates with the outside through the top of the roof structure. One end of each connecting hole communicates with the ventilation hole, and the other end of each connecting hole communicates with the water storage tank.

[0008] By adopting the above technical solution, in hot weather, the water in the water storage tank can reduce the rise in roof temperature, thereby reducing the impact of the roof temperature rise on the cavity temperature. The high temperature causes the water in the water storage tank to evaporate, and the water vapor can move to the outside of the house through the connecting holes and vents. As the water vapor leaves the house, it can carry away some of the heat from the roof. At the same time, the movement of water vapor can also promote air circulation between the inside of the house and the outside, so that the temperature in the cavity can be maintained within a comfortable living range, reducing the frequency of use of cooling appliances. While utilizing solar energy to absorb and store energy, it can also reduce the consumption of additional energy, resulting in better energy saving effect and greater green environmental protection.

[0009] Optionally, two water collection troughs are also provided on the top of the roof. The two water collection troughs are located at opposite ends of the top of the roof. One end of each water collection trough passes through the top of the roof, and the other end of each water collection trough is connected to a water storage tank.

[0010] By adopting the above technical solution, the water accumulated on the roof can enter the water storage tank through the water collection trough, so that the water stored in the water storage tank does not require additional water resources and can be reused, which is more green and environmentally friendly.

[0011] Optionally, a enclosure is provided above the roof, which surrounds several solar panels, and the enclosure and the top of the roof together form a groove, with the end of the water collection tank away from the water storage tank communicating with the groove.

[0012] By adopting the above technical solution, the collection and utilization rate of water accumulated on the roof can be improved, making it easier for rainwater to stay on the roof after falling on it, so that the rainwater has sufficient conditions to flow into the water storage tank for storage.

[0013] Optionally, the top of the roof is also provided with an installation frame for installing several solar panels. The installation frame includes two mounting plates and a connector. The mounting plates have a first mounting groove. The ends of the two mounting plates are hinged together by the connector. The end of the mounting plate away from the connector is slidably connected to the roof. The rotation axis of the mounting plate and its sliding direction are both horizontal and perpendicular to each other. The installation frame also includes a driving member for driving the connector to move in the vertical direction. The movement of the connector drives the mounting plates to move.

[0014] By adopting the above technical solution, the mounting frame can facilitate the installation and replacement of solar panels. After the driving component moves the connecting component, the two mounting plates can form a pointed structure, which can reduce the probability of rainwater staying on the solar panels for a long time, thereby reducing the damage of rainwater to the solar panels.

[0015] Optionally, the driving component has limitations in the movement of the connecting component. When the connecting component moves to the position closest to the top of the roof, the two mounting plates are located in the same horizontal plane, the mounting plates are in close contact with the top end face of the roof, and the two mounting plates respectively cover the ends of the two water collection tanks away from the water storage tank. When the connecting component moves to the position farthest from the top of the roof, the two mounting plates are in an inclined state with different inclination directions, the two mounting plates are located between the ends of the two water collection tanks away from the water storage tank, and the water collection tank is located near the lower inclined end of the adjacent mounting plate.

[0016] By adopting the above technical solution, when the sunlight is strong and suitable for absorbing solar energy, the driving component drives the connecting component to move until both mounting plates are against the roof. At this time, the solar panel has the largest absorption range for solar energy, and the mounting plates can cover the water collection tank, preventing water vapor in the water storage tank from leaving through the water collection tank, while also reducing the entry of impurities from the water collection tank. When it rains, the driving component drives the connecting component to move until both mounting plates are tilted. At this time, rainwater can flow along the tilted surface of the mounting plates towards the water collection tank, further facilitating the flow of rainwater into the water collection tank, while also reducing the probability of prolonged contact between the solar panel and rainwater.

[0017] Optionally, a filter element is provided at the end of the water collection tank away from the water storage tank of the roof, and the filter element has a plurality of filter holes. A blockage clearing element is provided at the end of the mounting plate away from the connector. During the movement of the connector, the blockage clearing element remains in contact with the filter element.

[0018] By adopting the above technical solution, the filter element can further reduce the amount of impurities entering the water storage tank through the water collection tank. When the mounting plate moves, the anti-clogging component can clean the filter element, reducing the probability of the filter holes on the filter element being blocked.

[0019] Optionally, it also includes a water storage tank, which is located on one side of the roof. A water supply pipe is connected between the water storage tank and the roof. One end of the water supply pipe is connected to the interior of the water storage tank, and the other end of the water supply pipe passes through the periphery of the water storage tank and is connected to the water storage tank. The position where the water collection tank is connected to the water storage tank is located above the position where the water supply pipe is connected to the water storage tank.

[0020] By adopting the above technical solution, the storage tank has a limited capacity for storing rainwater. Excess rainwater can be stored in the storage tank through the water pipe. The rainwater stored in the storage tank can also be reused through other means, which is more energy-efficient and environmentally friendly.

[0021] Optionally, a heat-absorbing component is also provided inside the roof top, located between the solar panel and the water storage tank.

[0022] By adopting the above technical solution, the heat-absorbing component can concentrate the heat from the roof, making the heat concentrated in a location away from the cavity, and making the cooling effect of the water in the water storage tank more obvious.

[0023] Optionally, a valve is provided at the end of the roof where the vent is away from the cavity.

[0024] By adopting the above technical solution, the valve can control whether the vent is connected to the outside. When the weather is hot, the valve is opened to allow the water vapor generated in the water tank to leave, while providing conditions for promoting indoor and outdoor air circulation. When the weather is cold, the valve is closed to reduce the rate at which the heat absorbed by the heat-absorbing component dissipates, thereby improving the insulation effect of the building.

[0025] In summary, this application includes at least one of the following beneficial effects:

[0026] 1. In hot weather, it can reduce the impact of the rising roof temperature on the temperature inside the cavity, and promote indoor and outdoor air circulation, making the environment inside the cavity more livable, reducing the frequency and duration of use of cooling appliances, reducing additional energy consumption, and making it more energy-efficient and environmentally friendly;

[0027] 2. In cold weather, the heat generated by the solar panels can be retained on the roof for a longer period of time, thus keeping the temperature in the cavity warm or even raising it. This reduces the frequency and duration of use of heating appliances, reduces additional energy consumption, and is more energy-efficient and environmentally friendly. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses an energy-saving house.

[0035] Reference Figure 1 The energy-saving house includes a roof structure 1 and several solar panels 2. The solar panels 2 are installed on top of the roof structure 1. The solar panels 2 absorb solar energy and convert it into electrical energy to power the electrical appliances inside the roof structure 1, and can also provide heating for the roof structure 1. In this embodiment, the solar panels 2 are common existing technology, so they will not be described in detail.

[0036] Reference Figure 1 and Figure 2 The roof 1 is a rectangular parallelepiped structure, and preferably a single-layer structure. The interior of the roof 1 has a cavity 11, and the perimeter of the roof 1 has doors and windows. The roof 1 has a top enclosure 12, which is located above the roof 1 and is distributed along the edge of the top end face of the roof 1, forming a groove 13 together with the top end face of the roof 1.

[0037] The roof 1 is equipped with a mounting frame 3 for easy loading and unloading of several solar panels 2. The mounting frame 3 is located in the groove 13. The mounting frame 3 includes two mounting plates 31 for mounting several solar panels 2. The mounting plates 31 are rectangular plate structures. The mounting plates 31 have first mounting slots 311 for mounting several solar panels 2 side by side. The same number of solar panels 2 can be installed on both mounting plates 31.

[0038] Reference Figure 2 and Figure 3The mounting frame 3 also includes a connector 32 for hinged connection of the two mounting plates 31. The connector 32 is cylindrical in shape, and one long side of each mounting plate 31 is rotatably connected to the connector 32. The axis of rotation of the mounting plate 31 coincides with the axis of the connector 32. Pulleys 312 are mounted on both sides of the mounting plate 31 away from the connector 32. A first sliding groove 121 for sliding the pulleys 312 is provided on the enclosure 12. The first sliding groove 121 communicates with the groove 13, and its length direction is horizontal and perpendicular to the axis of the connector 32. A second sliding groove 122 for the end of the connector 32 to be engaged is also provided on the enclosure 12. The second sliding groove 122 also communicates with the groove 13, and its length direction is vertical and perpendicular to the sliding direction of the first sliding groove 121. The two first sliding grooves 121 are symmetrically distributed along the length direction of the second sliding groove 122.

[0039] The mounting frame 3 also includes a driving component 33 for driving the connector 32 to slide. The top of the roof 1 is also provided with a second mounting groove 14 for mounting the driving component 33. The second mounting groove 14 communicates with the second sliding groove 122, and the driving component 33 is fixedly connected to the end of the connector 32. In this embodiment, the driving component 33 is preferably a cylinder.

[0040] Reference Figure 3 and Figure 4 The roof 1 also has a rainwater storage tank 15 and two collection tanks 16 for rainwater to flow into the rainwater storage tank 15. The rainwater storage tank 15 is located inside the roof 1, and the two collection tanks 16 are located at opposite ends of the roof 1. The collection tanks 16 are located above the rainwater storage tank 15, and the rainwater storage tank 15 is connected to the groove 13 through the collection tanks 16. A filter element 4 for filtering rainwater is installed at the end of the roof 1 away from the rainwater storage tank 15. The filter element 4 has several filter holes 41. After the filter element 4 is installed, the end face of the filter element 4 away from the rainwater collection tank 16 is flush with the end face of the roof 1.

[0041] When the driving member 33 drives the connecting member 32 to slide to the highest position, both mounting plates 31 are in an inclined state, with the end of the mounting plate 31 away from the connecting member 32 being the inclined lower end, and the two mounting plates 31 are symmetrical along the axis of the connecting member 32. At this time, the pulley 312 abuts against the groove wall of the first sliding groove 121 near the other first sliding groove 121, and the filter element 4 is located on the side of the adjacent mounting plate 31 away from the other mounting plate 31, and the filter element 4 is located on the side of the inclined lower end of the adjacent mounting plate 31.

[0042] When the driving component 33 drives the connecting component 32 to slide to the lowest position, both mounting plates 31 are in a horizontal state, the mounting plates 31 abut against the top of the roof 1, the ends of the two mounting plates 31 away from the connecting component 32 are respectively located above the two filter components 4, and the two mounting plates 31 simultaneously cover a number of filter holes 41.

[0043] Reference Figure 3 and Figure 4 A cleaning component 313 is installed at the end of the mounting plate 31 away from the connector 32. When the driving component 33 drives the connector 32 to slide, thereby moving the mounting plate 31, the cleaning component 313 remains in contact with the filter element 4. Furthermore, the cleaning component 313 can scrape away impurities from the surface of the filter element 4 during the movement of the mounting plate 31, reducing the probability of the filter holes 41 being clogged by impurities. In this embodiment, the cleaning component 313 is preferably made of rubber.

[0044] Reference Figure 1 , Figure 2 and Figure 3 A rain sensor 5 is also installed on the top of the roof 1. The rain sensor 5 can control the drive component 33 according to the weather conditions. When it is raining, the rain sensor 5 will control the drive component 33 to drive the connector 32 to the highest position, so that the rainwater on the top of the roof 1 can flow into the water storage tank 15 through the water collection trough 16. When it is not raining, the rain sensor 5 will control the drive component 33 to drive the connector 32 to the lowest position, and the mounting plate 31 will isolate the water collection trough 16 from the outside. In this embodiment, since the sensor that can sense rainwater is existing technology, it will not be described in detail here.

[0045] Reference Figure 2 and Figure 3 A heat absorber 6 is also installed inside the top of the roof 1. The heat absorber 6 is located on the side of the water storage tank 15 near the mounting frame 3, and is situated between the two water collection tanks 16. While the solar panel 2 absorbs solar energy and converts it into energy, it generates heat. During non-rainy weather, the heat is transferred to the top of the roof 1 through the mounting plate 31. Sunlight also causes the overall temperature of the roof 1 to rise. The heat absorber 6 can absorb and concentrate the heat from the top of the roof 1, reducing the impact of the increased temperature at the top of the roof 1 on the temperature inside the cavity 11. In this embodiment, the heat absorber 6 is preferably a vacuum insulation panel.

[0046] Reference Figure 3 and Figure 4 The roof 1 has several ventilation holes 17 located around the water storage tank 15. One end of each ventilation hole 17 extends through the perimeter of the roof 1 and communicates with the outside, while the other end communicates with the cavity 11. A connecting hole 18 is also provided between the ventilation holes 17 and the water storage tank 15 at the top of the roof 1, through which the ventilation holes 17 communicate with the water storage tank 15. A valve 7 is also installed at the end of the ventilation hole 17 furthest from the cavity 11 at the top of the roof 1. The opening and closing of the valve 7 controls whether the ventilation hole 17 communicates with the outside.

[0047] During hot, non-rainy weather, the heat-absorbing component 6 absorbs more heat. The high temperature at the top of the roof 1 will accelerate the evaporation of rainwater in the water storage tank 15. After the rainwater evaporates, it will take away some of the heat from the top of the roof 1, thus cooling the top of the roof 1. The water vapor generated by the evaporation of rainwater will enter the vent 17 through the connecting hole 18. At this time, the valve 7 is open. Then, the water vapor moves to the outside through the vent 17 due to its upward trend. The movement of water vapor can promote the air flow between the outside and the cavity 11, thereby making the temperature in the cavity 11 more suitable for living.

[0048] When the temperature is low and it is not rainy, the heat-absorbing component 6 absorbs less heat. At this time, the valve 7 is closed, reducing the air flow between the outside and the cavity 11, thereby giving the roof 1 a better heat preservation effect and reducing the loss of temperature in the cavity 11.

[0049] Reference Figure 2 and Figure 3 A temperature sensor 8 is also installed on the exterior of the roof 1. The temperature sensor 8 can sense the ambient temperature. When the temperature sensor 8 senses that the outside temperature is below a certain value, it controls the valve 7 to close; when the temperature sensor 8 senses that the outside temperature is above a certain value, it controls the valve 7 to open. In this embodiment, since the temperature sensor is existing technology, it will not be described in detail here.

[0050] Reference Figure 1 and Figure 3 A water storage tank 9 for collecting rainwater is also installed on one side of the roof 1. A water supply pipe 91 is connected between the water storage tank 9 and the roof 1. One end of the water supply pipe 91 is fixedly connected to the water storage tank 9 and communicates with the inside of the water storage tank 9. The other end of the water supply pipe 91 is fixedly connected to the roof 1 and passes through the top of the roof 1 and communicates with the water storage tank 15. The position where the water supply pipe 91 communicates with the water storage tank 15 is higher than the bottom of the water storage tank 15 and lower than the position where the connecting hole 18 communicates with the water storage tank 15.

[0051] During rainy weather, rainwater enters the storage tank 15 through the collection trough 16. When the amount of rainwater stored in the storage tank 15 is too much, the excess rainwater will flow into the storage tank 9 through the water pipe 91 for storage.

[0052] Reference Figure 3 and Figure 4The roof structure 1 is equipped with a monitoring device 10 in the water storage tank 15 to monitor the amount of rainwater stored in the water storage tank 15. A water supply pipe 92 is connected between the water storage tank 9 and the roof structure 1. The water supply pipe 92 is similar to the water transmission pipe 91, with both ends connected to the interior of the water storage tank 9 and the water storage tank 15, respectively. A first water pump 93 is also installed on the water supply pipe 92 to drive rainwater from the water storage tank 9 to the water storage tank 15. The first water pump 93 is located in the water supply pipe 92 and at the end of the water supply pipe 92 closest to the water storage tank 15. When the monitoring device 10 detects that the amount of rainwater stored in the water storage tank 15 is less than a certain amount, the monitoring device 10 will control the first water pump 93 to drive rainwater through the water supply pipe 92 from the water storage tank 9 into the water storage tank 15.

[0053] A drain pipe 94 is connected between the water storage tank 9 and the roof 1. Both ends of the drain pipe 94 are connected to the interior of the water storage tank 9 and the water storage trough 15, respectively. The connection point between the drain pipe 94 and the water storage trough 15 is lower than the connection point between the water supply pipe 91 and the water storage trough 15. A second water pump 95 is also installed on the drain pipe 94 to drive rainwater from the water storage trough 15 to the water storage tank 9. The second water pump 95 is located within the drain pipe 94 and at the end of the drain pipe 94 closest to the water storage trough 15. When the temperature sensor 8 senses that the outside temperature of the roof 1 is lower than a certain value, the temperature sensor 8 will control the second water pump 95 to drive rainwater through the drain pipe 94 from the water storage tank 15 into the water storage tank 9, so that all the rainwater stored in the water storage tank 15 is transferred to the water storage tank 9 for storage. At this time, the heat absorption element 6 absorbs heat and can heat the air in the water storage tank 15. The air in the water storage tank 15 can also exchange heat with the air in the cavity 11 through the connecting hole 18 and the vent hole, thereby achieving a heating effect and improving the insulation effect of the roof 1.

[0054] The implementation principle of an energy-saving house according to an embodiment of this application is as follows:

[0055] During hot weather, valve 7 is opened, and solar panel 2 can absorb solar energy and convert it into other energy sources for use. When solar panel 2 is working, it generates heat, which is transferred to the top of roof 1. Heat absorber 6 can concentrate the heat at the top of roof 1. The rainwater stored in water tank 15 can slow down the temperature rise at the top of roof 1. At the same time, high temperature will accelerate the evaporation of rainwater. Water vapor can carry away some heat as it moves to the outside through connecting hole 18 and vent hole 17. It can also promote air circulation inside and outside roof 1, making the temperature in cavity 11 more suitable and reducing the frequency and duration of use of cooling appliances. During this process, the first water pump 93 will drive the rainwater in water tank 9 to continuously replenish water tank 15 through water supply pipe 92.

[0056] In cold weather, valve 7 is closed, and solar panel 2 continues to absorb solar energy and convert it into other energy sources for use. When solar panel 2 is working, it generates heat, which is transferred to the top of roof 1. Heat absorber 6 can concentrate the heat at the top of roof 1. Meanwhile, rainwater in water storage tank 15 is driven by second water pump 95 to flow into water storage tank 9 through drain pipe 94 for storage. At this time, the heat will heat the air in water storage tank 15, thereby raising the temperature in cavity 11 and providing a better heat preservation effect.

[0057] During rainy weather, the rain sensor 5 will drive the connector 32 to slide, thereby causing the two mounting plates 31 to move and change their state, so that rainwater can be filtered by the filter element 4 and enter the water storage tank 15 through the water collection tank 16 for storage. Excess rainwater will be stored in the water storage tank 9 through the water supply pipe 91. During the movement of the mounting plate 31, the unblocking component 313 can also unblock the filter element 4, reducing the probability of the filter hole 41 being blocked.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
