The solar water heater is popular with consumers because of the advantages of energy saving, environmental protection and convenient use. Before using hot water in a water storage tank of a solar water heater, residual cold water in a water pipe is generally required to be removed completely; the water storage tank of the existing solar water heater is generally far away from a user, namely a water pipe for the water storage tank needs to be arranged longer, so that the residual cold water in the water pipe is larger, and larger water resource waste is caused.

In view of this, the present invention provides an internal circulation water-saving solar water heater water pipe, and fig. 1 to 5 show an embodiment of the internal circulation water-saving solar water heater water pipe provided by the present invention.

Referring to fig. 1 to 3, the water pipe of the internal circulation water saving type solar water heater provided by the present invention includes a water pipe main body 1 and a pump body (not shown in the drawings), wherein the water pipe main body 1 includes an outer pipe 11 and an inner pipe 12 sleeved inside and outside, an inner wall of the outer pipe 11 is spaced from an outer wall of the inner pipe 12 to define a water supply channel 13 at the spaced position, wherein a water inlet end of the water supply channel 13 is used for communicating with a water storage tank 200 of the solar water heater, a water inlet end of the inner pipe 12 is communicated with the water supply channel 13, and a water outlet end of the inner pipe 12 is used for communicating with the water storage tank 200; the pump body acts on the inner pipe 12 so that the water in the water supply channel 13 is sucked to the water storage tank 200 through the inner pipe 12.

In the technical scheme provided by the invention, before the hot water in the water storage tank 200 is used, the pump body can be operated to make the cold water remained in the water supply channel 13 flow back into the water storage tank 200 through the inner pipe body 12, so that the returned cold water and the original water in the water storage tank 200 are heated by the solar water heater and then flow to a user from the water supply channel 13 for use, thereby being beneficial to reducing the waste of water resources and realizing energy conservation and environmental protection.

The outer tube 11 and the inner tube 12 may be integrally formed, in this case, the outer tube 11 and the inner tube 12 are made of the same material, and at least a connection structure is formed between the outer tube 11 and the inner tube 12, and the connection structure may be a connection arm, and the connection arm may be formed at any position of the water pipe main body 1. Of course, the outer tube 11 and the inner tube 12 may be provided separately, in which case, the outer tube 11 and the inner tube 12 may be made of different materials, for example, the outer tube 11 may be made of a material having a greater strength than the inner tube 12, or the outer tube 11 may be made of a material having a greater wall thickness than the inner tube 12; the inner tube 12 is inserted into the outer tube 11.

The inner tube 12 may be suspended within the outer tube 11 such that the water supply channel 13 formed is annularly arranged; of course, the inner tube 12 may also be disposed on one side wall of the outer tube 11 and spaced apart from another side wall of the outer tube 11 to define the water supply channel 13 at the spaced apart locations. The water inlet end of the outer pipe body 11 is used for communicating the water storage tank 200, and the water outlet end of the outer pipe body 11 is used for users to use; the water inlet end of the inner pipe 12 is communicated with the water supply channel 13, so that the water inlet end of the inner pipe 12 is formed in the outer pipe 11; the water outlet end of the inner tube 12 is used to communicate with the water storage tank 200, and the pump body is disposed in the inner tube 12, and may be disposed in the water storage tank 200.

In the present embodiment, the shape and specific size of the inner tube 12 and the outer tube 11 are not limited in the present design, and the shape and specific size of the water supply channel 13 formed are also not limited in the present design. The cross-sectional area of the water supply channel 13 is not smaller than the cross-sectional area of the inner tube 12, and the use frequency of the water supply channel 13 is much larger than the use frequency of the inner tube 12, so that the cross-sectional area of the inner tube 12 is smaller, which is beneficial to reducing the space occupied by the inner tube 12 in the outer tube 11 and increasing the water flow of the water supply channel 13.

The inner pipe 12 can suck water in the water supply channel 13 back into the water storage tank 200 through a water inlet hole at an end portion thereof, and besides, in the present embodiment, the inner pipe 12 is provided with a plurality of water delivery holes 121 communicating with the water supply channel 13; the plurality of water delivery holes 121 are dispersedly arranged along the outer circumferential side wall of the inner pipe body 12; the water inlet hole at the end of the inner pipe body 12 belongs to one of the water delivery holes 121. Specifically, the plurality of water delivery holes 121 are distributed along the circumferential direction and the axial direction of the inner pipe 12, so that water corresponding to the plurality of water delivery holes 121 in the water supply channel 13 can be quickly pumped into the water storage tank 200.

Further, in the present embodiment, the openings of the water delivery holes 121 are at least partially disposed differently. It will be appreciated that, under the driving of the pump body, the water near the water delivery hole 121 is preferentially sucked, and the area far from the water delivery hole 121 forms a dead zone in which the water is sucked late or even not sucked, which may cause the water in the water supply channel 13 not to be completely sucked and may reduce the efficiency of the water in the water supply channel 13 being sucked. The openings of the water delivery holes 121 are directed to be at least partially arranged differently, which helps to enlarge the action area of the water delivery holes 121, thereby eliminating the blind area.

Further, in this embodiment, the pump body is configured to be disposed in the water storage tank 200; the diameters of the water delivery holes 121 are gradually reduced in a direction approaching the water storage tank 200. It can be understood that the larger the aperture of the water inlet hole 121, the larger the water flow rate passing through, but the more difficult it is to form negative pressure in the inner pipe body 12; conversely, the smaller the diameter of the water inlet hole 121 is, the easier the negative pressure is to be formed in the inner pipe 12, but the water flow rate is smaller; in addition, a section of the inner tube 12 close to the pump body is easier to form negative pressure than a section of the inner tube away from the pump body, so that the tapered arrangement of the embodiment enables one end of the inner tube 12 close to the pump body to form a negative pressure condition for one end of the inner tube 12 away from the pump body, thereby effectively guaranteeing the pumping efficiency.

Referring to fig. 4 and 5, in the present embodiment, the water pipe body 1 further includes a plurality of adjusting members, and the plurality of adjusting members are disposed corresponding to the plurality of water delivery holes 121; wherein each of the adjusting members is deformable by an external force to communicate the inner tube 12 with the water supply passage 13, and is reset to block the inner tube 12 from the water supply passage 13 when the external force is removed. The regulating member is capable of opening the water delivery hole 121 when the inner pipe body 12 is operated, thereby ensuring that water is rapidly sucked; on the contrary, when the inner tube 12 does not work, the adjusting member can close the water delivery hole 121, so as to reduce the influence on the normal operation of the water supply channel 13. In practical applications, the external force can be provided by the negative pressure formed by the pump body in the inner tube 12, which can effectively open and close the water inlet hole 121, and can avoid the complexity of the structure and simplify the operation.

Of course, there are various technical solutions for the adjusting member to achieve the above functions, for example, the adjusting member is a door body, the installation end of the door body is rotatably installed on the water delivery hole 121 through a torsion spring, and the movable end of the door body can rotate around the installation end of the door body under the pushing of an external force, so as to open the water delivery hole 121; on the contrary, when the external force is removed, the movable end of the door body can be restored to cover the water delivery hole 121 under the action of the torsion spring. In this embodiment, the adjusting member is an elastic wall 14, the elastic wall 14 is provided with at least one slit 141, and the slit 141 can be elastically expanded to be exposed under the action of an external force and can be restored to be closed when the external force is removed. The elastic wall 14 may be fixed to the periphery of the water inlet hole 121 by adhesion or adsorption. The slit 141 may be provided in one or more. When the pump body works, negative pressure is formed in the inner tube 12, and the pressure outside the inner tube 12 is greater than the pressure inside the inner tube 12, at this time, pressure is applied to the elastic wall 14 from outside the inner tube 12, and the pressure causes the elastic wall 14 to bend and deform, so that the slit 141 is expanded to form a through hole; on the contrary, when the pump body is closed, the internal and external pressures of the inner tube 12 are equal, and at this time, the elastic wall 14 is not stressed and therefore is not deformed, and the slit 141 is closed.

Next, referring to fig. 3, in the present embodiment, the water pipe main body 1 further includes at least one mounting bracket 15, and the mounting bracket 15 includes an outer ring 151, an inner ring 152, and a reinforcing rib 153 connecting the inner ring 152 and the outer ring 151; the outer ring 151 is configured to be fixed on the inner wall of the outer tube 11, and the inner ring 152 is configured to be fixed on the outer wall of the inner tube 12. The mounting bracket 15 may be used to suspend the inner pipe 12 such that the water supply passage 13 is annularly disposed around the outer circumference of the inner pipe 12. The mounting bracket 15 can be arranged in one or more than one in the water pipe main body 1; the mounting bracket 15 can be integrally formed with the inner wall of the outer tube 11 or the outer wall of the inner tube 12; of course, the mounting bracket 15 may be separately disposed from the inner wall of the outer tube 11 or the outer wall of the inner tube 12, and then be limited between the inner tube 12 and the outer tube 11 by fastening or bonding. The reinforcing rib 153 can enhance the connection strength between the inner ring 152 and the outer ring 151 and can provide enough space for water to pass through.

Further, in the present embodiment, the inner ring 152 and the outer ring 151 are disposed in a concentric circle. By the arrangement, the formed water supply channel 13 is in a regular ring shape, so that water circulating through the water supply channel 13 is approximately balanced and uniform in all places, and the normal use of the water pipe body 1 is not influenced.

In addition, in this embodiment, the internal circulation water-saving solar water heater water pipe further includes a switch circuit (not shown in the drawings), and the switch circuit is configured to electrically connect the pump body and the solar water heater, so as to control the pump body to operate when a water supply period of the solar water heater exceeds a preset period. Specifically, when the time interval between two adjacent hot water supplies exceeds the preset time interval, it can be understood that the temperature of the water remaining in the water pipe main body 1 is low and needs to be removed completely before the next hot water supply, and at this time, the pump body can be controlled to work through the switch circuit, so as to achieve the above effect of the internal circulation water-saving solar water heater water pipe; on the contrary, when the time interval between two adjacent hot water supplies does not exceed the preset time interval, it can be understood that the temperature of the water remaining in the water pipe main body 1 is still high, the water does not need to be drained completely before the next hot water supply, the solar water heater can be directly used continuously, and at the moment, the pump body can be controlled to be closed through the switch circuit, so that the energy conservation and the consumption reduction are facilitated.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
