Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum tube solar water heaters, in particular to an intelligent sunshade device for vacuum tube solar water heaters. Background Art

[0002] Vacuum tube solar water heaters need to be installed on the roof. When purchasing a solar water heater, users tend to buy as many vacuum tubes as possible and a larger water tank to ensure hot water supply in winter or during consecutive rainy days. This means that during spring, summer, and autumn, when there are many consecutive sunny days, especially in summer, when water consumption is low, the water in the tank will boil in just two or three days. If the water is not used for a long time, such as when traveling or on business, the water tank will be exposed to high temperatures for a long time, which will accelerate the aging of the silicone seal and the corrosion of the stainless steel in the water tank. The insulation material will also age, shortening the lifespan of the water heater. Although many patents have been applied for for automatic solar shading, due to the complex structure and high cost, it has not been widely used. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an intelligent sunshade device for vacuum tube solar water heaters with reasonable design and convenient use, in view of the deficiencies in the prior art.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] An intelligent sunshade device for an evacuated tube solar water heater comprises a bracket and a water heater body provided with an evacuated tube, the water heater body being mounted on the bracket. The device is characterized in that a sunshade mechanism for shading the water heater body and a control mechanism for controlling the sunshade area are mounted on the bracket.

[0006] The sunshade mechanism includes a sunshade curtain extending from the bottom to the top of the water heater body to cover the vacuum tube and a guide groove provided on both sides of the water heater body. The length of the guide groove is greater than or equal to the length of the vacuum tube on the water heater body. A drive cylinder for pulling open the sunshade curtain is installed in the guide groove. The two corners of the bottom edge of the sunshade curtain are respectively fixed to the bottom ends of both sides of the water heater body.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] Reference Figure 1-4 An intelligent sunshade device for a vacuum tube solar water heater, comprising a bracket 1 and a water heater body mounted on the bracket 2, a sunshade mechanism 3 for shading the water heater body and a control mechanism for controlling the sunshade area being mounted on the bracket;

[0021] The sunshade mechanism 3 includes a sunshade curtain 5 extending from the bottom to the top of the water heater body to cover the vacuum tube 4, and a guide groove 6 provided on both sides of the water heater body. The length of the guide groove 6 is greater than or equal to the length of the vacuum tube 3 on the water heater body. A drive cylinder for opening the sunshade curtain is installed in the guide groove 6. The two corners of the bottom edge of the sunshade curtain are respectively fixed to the bottom ends of both sides of the water heater body. The two corners of the top edge of the sunshade curtain 5 are respectively connected to the piston rods of the drive cylinders on both sides of the water heater body. The top of the piston rod of the drive cylinder is also provided with a slider that cooperates with the guide groove.

[0022] The control mechanism includes a controller and a temperature sensor for detecting the temperature of the water heater body. The temperature sensor and drive cylinder are both controllably connected to the controller. A voice announcer and a flashing light with reminder functions are mounted on the bracket and are both connected to the controller. Because the sunshade is a black mesh structure, when the piston rod of the drive cylinder is retracted to its innermost end, the sunshade accumulates at the bottom of the vacuum tube, without affecting the operation of the water heater body or the use of the subsequent sunshade mechanism.

[0023] A plurality of position sensors for detecting the extension length of the piston rod of the driving cylinder are installed on the inner wall of the guide groove. The position sensors are arranged side by side along the axis of the guide groove, and the sunshade area is controlled by the position sensors.

[0024] A mounting hole for mounting a sunshade is provided at the top end of the piston rod of the driving cylinder, and a hook for hanging the sunshade is connected to the mounting hole through a flexible elastic rope or a thin nylon rope.

[0025] When the vacuum tube 3 solar water heater is installed, place the sunshade on the vacuum tube, and then connect the installation holes of the sunshade with a flexible elastic rope or a thin nylon rope. Hooks can be installed at both ends of the elastic rope for easy connection.

[0026] The optimal water tank temperature for a solar water heater is between 65°C and 85°C. This higher water temperature is less conducive to the growth of bacteria and microorganisms, making it easier to adjust the temperature between hot and cold water. For example, a solar water heater with 20 vacuum tubes has a sunshade and cord costing only 8-10 yuan. Installation takes only 3-5 minutes, and adjustment takes only 1 minute.

[0027] In summer, when fully shaded, the water temperature in the water heater tank can be maintained at 40-45°C for extended periods, making this mode ideal for users who are away for extended periods. For normal summer use, the 70% shade mode can be selected, maintaining a constant water temperature of 65-75°C. In early spring and late autumn, the 30% shade mode can be selected, maintaining a constant water temperature of 75-85°C. In winter, due to higher water consumption, a non-shading mode is used. Alternatively, the system can be switched from non-shading to semi-shading in spring and from semi-shading to non-shading in late autumn, with adjustments made twice a year. These varying shade modes are determined by the shade's coverage area, which can be adjusted via the controller and the extension length of the drive cylinder.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
