Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to a space energy water heater. Background Art

[0002] Space energy water heater is a new type of water heater that uses solar energy and air energy to convert into heat energy, saving energy. Existing space energy water heaters include solar collectors and heat pumps that absorb solar heat energy. The key component of the solar collector, the heat collecting tube, is only exposed to sunlight from the front during use, and the heat collection efficiency of the heat collecting tube still has room for improvement.

[0003] For example, the Chinese patent with publication number CN205037589U discloses an intelligent space energy water heater, which includes a bracket, a heat collecting tube, an insulated water tank fixed on the bracket, and an air source heat pump. One end of the heat collecting tube is connected to the insulated water tank, and the other end is connected to the lower end of the bracket. A reflector is provided at the backlight of the heat collecting tube to enhance the solar radiation of the heat collecting tube. The reflector is a stainless steel sheet and is fixed to the bracket. A thin-walled stainless steel sealed blind pipe with an outward opening at the bottom of the inner tank of the insulated water tank is provided. The air source heat pump is connected to the insulated water tank through a heat exchanger. A temperature sensor is provided in the insulated water tank, and an intelligent controller is also provided, which is respectively connected to the temperature sensor and the air source heat pump. The intelligent controller of the utility model starts the air source heat pump for heating when the temperature sensor detects that the water temperature is lower than the set temperature value, and shuts down the air source heat pump when the temperature sensor detects that the water temperature reaches the set temperature value, which is energy-saving and environmentally friendly.

[0004] The existing technology has the following problems:

[0005] The water heater uses sunlight to heat the water, but due to the rotation of the earth, the direction of the light directed to the water heater will rotate with the rotation of the earth, so that the sunlight will only directly hit the heating position of the water heater part of the time. At other times, the sunlight will shine on it obliquely, causing the heating power to decrease, and the sunlight may even shine on the back of the water heater, making it unable to operate.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figure 1-Figure 6 As shown, a space energy water heater comprises a water tank 1, a rotating device 2 is sleeved in the middle of the upper surface of the water tank 1, a water circulation device 3 is fixedly connected to the top of the rotating device 2, a heating device 4 is fixedly connected to the top of the water circulation device 3, a shielding device 5 is fixedly connected to the top of the heating device 4, and solar panels 6 are respectively embedded in the upper surface of the water tank 1 near the left and right sides;

[0032] It should be noted that the water tank 1 contains water to be heated, and the solar panel 6 supplies power to the electrical components inside the water heater;

[0033] The rotating device 2 includes a bottom shell 21, which is sleeved on the middle of the upper surface of the water tank 1, and a base 22 is fixedly connected to the upper surface of the bottom shell 21;

[0034] It should be noted that the bottom shell 21 is used to support the water circulation device 3, the heating device 4 and the shielding device 5 above to prevent them from pressing the water tank 1 and causing the water tank 1 to sink inward, and the base 22 is used to separate the water circulation device 3 and the heating device 4 so that the lower half of the water circulation device 3 does not rotate synchronously with the heating device 4;

[0035] The water circulation device 3 includes a water tank a31 and a water tank b32. The water tank a31 is fixedly connected to the inner lower surface of the base 22 near the edge, and the water tank b32 is fixedly connected to the axis of the inner lower surface of the base 22. The axis of the upper surface of the water tank b32 is rotatably connected to a rotating tank 33.

[0036] It should be noted that the water tank a31 is used to receive the water that has passed through the heating plate 43, and the water tank b32 is used for the water that has yet to pass through the heating plate 43. The lower part of the rotating tank 33 is closely attached to the water tank b32 to prevent air leakage from the water tank b32.

[0037] The heating device 4 includes a column shell 41, the inner side of the column shell 41 near the bottom is fixedly connected to the side of the rotating groove 33, and the inner side of the column shell 41 near the top is fixedly connected to a heating plate 43;

[0038] It should be noted that there are a large number of unidirectional and evenly distributed water channels on the upper part of the heating plate 43, and the water channel at the position of the same diameter passing through the lower surface of the heating plate 43 is the longest, and the two ends of the water channel are connected to each other. According to the normal distribution, the most water flows through the middle water channel, so a longer water channel is needed for heating. The amount of water passing through the water channels on both sides is small, so the heating time is short, and the heating plate 43 heats up after being exposed to sunlight.

[0039] like Figure 1 As shown, the shielding device 5 is fixedly connected at the middle of the bottom to the front and rear sides of the outer side of the column shell 41 near the top.

[0040] It should be noted that the shielding device 5 includes a movable frame and a sunshade cloth so that when the water heater is not in use, the shielding device 5 can be used to cover the heating device 4 to prevent the heating device 4 from being exposed to sunlight.

[0041] like Figure 3 As shown, a motor 23 is fixedly connected to the middle of the inner lower surface of the bottom shell 21 , a rotating shaft 24 is fixedly connected to the axis center of the upper surface of the motor 23 , and the axis center of the upper surface of the rotating shaft 24 is fixedly connected to the axis center of the lower surface of the rotating groove 33 .

[0042] It should be noted that the motor 23 drives the rotating shaft 24 to rotate, and the rotation speed of the motor 23 is very slow, at a speed of 1 revolution / 24 hours. When the rotating shaft 24 rotates, the rotating groove 33 is driven to rotate.

[0043] like Figure 4 As shown, corresponding notches are opened on the lower surface of the rotating groove 33 at positions corresponding to the water groove a31 and the water groove b32, and a water pump 34 is fixedly connected to a position near the right side of the upper surface of the rotating groove 33.

[0044] It should be noted that the water pump 34 is used to pump water from the water tank b32 to the upper right side of the heating plate 43, and the flow rate of the water pumped to the upper side of the heating plate 43 by the water pump 34 is relatively low.

[0045] like Figure 1 , Figure 4 and Figure 5 As shown, a water pipe a35 is fixedly connected between the water tank a31 and the upper surface of the water tank 1 near the left side, between the water tank b32 and the upper surface of the water tank 1 near the right side, between the position on the left side of the upper surface of the rotating trough 33 corresponding to the water tank a31 and the upper surface of the heating plate 43 near the left side, and the inner cavities of the water tank a31, the water tank 1 and the water tank b32 and the upper side of the heating plate 43 are connected through the water pipe a35.

[0046] It should be noted that the water pipe a35 on the water tank b32 will penetrate the water tank a31 and connect with the water tank b32. Water enters the water tank b32 from the inside of the water tank 1 along the water pipe a35 on the right. The water pipe a35 on the heating plate 43 enters the water tank a31 and then flows back to the water tank 1 through the water pipe a35 on the left.

[0047] like Figure 2 and Figure 4 As shown, a water pipe b36 is fixedly connected between the rear side of the water pump 34 and the upper surface of the rotating trough 33 near the position corresponding to the water tank b32 on the right side, and between the front of the water pump 34 and the lower surface of the heating plate 43 near the right side, and the inner side of the water tank b32, the inside of the water pump 34 and the top of the heating plate 43 are connected through the water pipe b36.

[0048] It should be noted that water flows from the water tank b32 along the water pipe b36 into the water pump 34 , and then flows from the water pump 34 along the water pipe b36 on the front side of the water pump 34 into the top of the heating plate 43 .

[0049] like Figure 6 As shown, the angle between the upper surface of the column shell 41 and the horizontal plane is 27-37 degrees, and the lower surface of the heating plate 43 and the upper surface of the column shell 41 are parallel to each other.

[0050] It should be noted that, on the vernal equinox: the sun is directly above the equator at 0°, and the solar altitude angle at noon in Beijing on that day is 50°; on the summer solstice: the sun is directly above the equator at 23°26′, and the solar altitude angle at noon in Beijing on that day is 73°26′; on the autumnal equinox: the sun is directly above the equator at 0°, and the solar altitude angle at noon in Beijing on that day is 50. In order to make the sunlight as perpendicular to the heating plate 43 as possible to achieve the highest heating efficiency, it is necessary to consider the solar altitude angle with the ground on the vernal equinox, summer solstice and autumnal equinox, which ranges from 25 to 40 degrees, with an average of 32.5 degrees. Taking the error into consideration, the range is increased to 27-37 degrees. When the angle between the upper surface of the column shell 41 and the ground is 27-37 degrees, the water heater can keep the heating plate 43 facing the sun for as long as possible.

[0051] like Figure 6 As shown, a lens 44 is sleeved on the inner side of the column shell 41 near the top, and a support beam 42 is fixedly connected to the front and rear sides of the inner side of the column shell 41, and the middle part of the lower surface of the support beam 42 is fixedly connected to the axis of the upper surface of the rotating groove 33;

[0052] It should be noted that the lens 44 gathers light to increase the heating efficiency, and the focus of the lens 44 is below the heating plate 43 to avoid damage to the heating plate 43 due to excessive temperature at the focus of the lens 44.

[0053] The working principle of the utility model is as follows: first, the motor 23 drives the rotating shaft 24 to rotate, thereby causing the rotating groove 33 to rotate, and then driving the column shell 41 to rotate, so that the upper surface of the lens 44 is always facing the side where the sunlight is directly exposed, so that the working efficiency of the water heater is always at a high position, accelerating the heating rate, and solving the problem that the water heater cannot maintain a high working efficiency for a long time. Finally, water is pumped from the water tank 1 by the water pump 34, and the water enters the interior of the water tank b32 from the water tank 1, and is then sent to the right side of the upper surface of the heating plate 43. By gravity, it flows to the left side and enters the interior of the water tank a31, and then returns to the interior of the water tank 1. The whole water is diverted into small streams of water. Through small amounts of multiple heating, the heating efficiency of the water heater is increased, so that the water can contact the heating plate 43 as much as possible, avoiding Heating the water at one time means that it takes a long time to heat the inside from the outside, which reduces the heating efficiency. Finally, the light is polymerized through the lens 44 to increase the heat of the light. When the water enters the water channel on the heating plate 43, due to the principle of normal distribution, most of the water enters the middle water channel and a small part enters the water channels on both sides. The heating plate 43 can absorb the internal energy generated by the sunlight to heat the water passing through it. The water channel contained in the upper part of the heating plate 43 further disperses the water, thereby improving the utilization of sunlight. Compared with traditional solar collectors, water is attached to the surface of the heating plate 43 in a planar form, and the amount of water in direct contact with the heating plate 43 is greater. At the same time, the heating plate 43 is a whole, and the number of solar collectors needs to be increased to increase the heating efficiency, resulting in an increase in volume.

[0054] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
