Flexible water hose and water heater unit

Abstract

This invention discloses a flexible water pipe and a hot water unit. The flexible water pipe includes an outer pipe and a deformation pipe disposed inside the outer pipe, forming a flow channel between the deformation pipe and the outer pipe. The deformation pipe can deform in response to pressure changes within the flow channel. The flexible water pipe and hot water unit of this invention utilize the deformation of the deformation pipe to buffer and eliminate water hammer phenomena within the flow channel, overcoming the problem of severe water hammer damage to the water system in existing technologies. This effectively ensures the reliability of the hot water unit, increases the heat exchange capacity of the water tank, and achieves comfortable operation of the entire unit. Simultaneously, the deformation pipe accumulates pressure during deformation; when the pressure within the flow channel is insufficient, the deformation pipe can return to its original shape and release the pressure, thereby replenishing the pressure within the flow channel and preventing insufficient water flow inside the unit from affecting the entire water system. This can directly replace the expansion tank in existing technologies, improving the energy efficiency of the hot water unit.

Description

Technical Field

[0001] This invention relates to the field of air handling equipment technology, and more specifically, to a flexible water pipe and a hot water unit. Background Technology

[0002] Large-capacity multi-functional hot water units emerged to meet market demand. The difference between them and small-capacity multi-functional hot water units lies in their cooling capacity. Small-capacity units, due to their smaller cooling capacity, can be flexibly configured for various European homes and villas, essentially operating on a single-use basis with a relatively independent water system and flexible configuration options. Large-capacity units, on the other hand, must be designed for multi-user use, making the water system more complex, especially when used by multiple users. The water tank capacity of these units is typically 500L or 1000L, and the actual water flow rate is very high, requiring a correspondingly high pump head. During mode switching, water hammer can occur, severely impacting the water system and causing poor reliability of the hot water unit. Summary of the Invention

[0003] This invention discloses a flexible water pipe and a hot water unit, which solves the problem of poor reliability of hot water units caused by water hammer in the prior art.

[0004] This invention discloses a flexible water pipe, comprising:

[0005] outer tube;

[0006] A deformation tube is disposed inside the outer tube, and a flow channel is formed between the deformation tube and the outer tube;

[0007] The deformation tube can deform in response to pressure changes within the flow channel.

[0008] The flexible water pipe also includes:

[0009] An inner tube is disposed inside the deformable tube, and there is a gap between the inner tube and the deformable tube;

[0010] A support structure is provided within the spacing, and the support structure is capable of deforming with the deformation of the deformation tube.

[0011] The support structure includes an airbag, a portion of the sidewall of which abuts against the inner wall of the deformation tube, and a portion of the sidewall of which abuts against the outer wall of the inner tube.

[0012] The support structure includes a plurality of support rings arranged sequentially along the axis of the inner tube, and each support ring includes at least two airbags.

[0013] The flexible water pipe also includes a connecting branch pipe, one end of which is connected to the flow channel and the other end of which is connected to the interior of the inner pipe.

[0014] The connecting branch pipe is equipped with an on / off mechanism.

[0015] The inner tube is equipped with a descaling agent and / or a disinfectant.

[0016] The deformation tube is equipped with a water quality testing mechanism, which is electrically connected to the on / off mechanism.

[0017] The outer pipe is equipped with a water quality testing mechanism, which is electrically connected to the on / off mechanism.

[0018] Another aspect of the present invention provides a hot water unit including the aforementioned flexible water pipe.

[0019] The flexible water pipe and hot water unit of this invention utilize the deformation of the deformation pipe to buffer and eliminate water hammer in the flow channel, overcoming the problem of water hammer severely damaging the water system in the prior art. This effectively ensures the reliability of the hot water unit, increases the heat exchange capacity of the water tank, and achieves comfortable operation of the entire unit. At the same time, when the deformation pipe deforms, it accumulates a certain amount of pressure. When the pressure in the flow channel is insufficient, the deformation pipe can return to its original shape and release the pressure, thereby replenishing the pressure in the flow channel and preventing insufficient water flow inside the unit from affecting the entire water system. It can directly replace the expansion tank in the prior art, simplify the internal space of the hot water unit, optimize the internal flow field of the hot water unit, and improve the energy efficiency of the hot water unit.

[0022] The present invention will be further described below with reference to embodiments, but is not limited to the contents of the specification.

[0023] like Figure 1As shown, this invention discloses a flexible water pipe, comprising: an outer pipe 1; and a deformable pipe 2, wherein the deformable pipe 2 is disposed inside the outer pipe 1, and a flow channel is formed between the deformable pipe 2 and the outer pipe 1; the deformable pipe 2 can deform with the pressure change in the flow channel. The deformation of the deformable pipe 2 buffers and eliminates water hammer in the flow channel, overcoming the problem of water hammer severely impacting the water system in existing technologies, effectively ensuring the reliability of the hot water unit, increasing the heat exchange capacity of the water tank, and achieving comfortable operation of the entire unit. Simultaneously, when the deformable pipe 2 deforms, it accumulates a certain pressure. When the pressure in the flow channel is insufficient, the deformable pipe 2 can return to its original shape and release the pressure, thereby replenishing the pressure in the flow channel and preventing insufficient water flow inside the unit from affecting the entire water system. It can directly replace the expansion tank in existing technologies, simplifying the internal space of the hot water unit, optimizing the internal flow field of the hot water unit, and improving the energy efficiency of the hot water unit.

[0024] Specifically, the flexible water pipe further includes: an inner pipe 3, which is disposed within the deformable pipe 2, and a gap exists between the inner pipe 3 and the deformable pipe 2; and a support structure, which is disposed within the gap and can deform with the deformation of the deformable pipe 2. The inner pipe 3 and the support structure support the deformable pipe 2, ensuring that the deformable pipe 2 can be reliably disposed within the outer pipe 1. Simultaneously, the support structure can deform with the deformation of the deformable pipe 2, further increasing the deformation capacity of the deformable pipe 2 and the pressure it can accumulate, thereby improving the pressure buffering and pressure compensation effect of the deformable pipe 2.

[0025] The support structure includes an airbag 4, with a portion of the sidewall of the airbag 4 abutting against the inner wall of the deformation tube 2 and another portion of the sidewall of the airbag 4 abutting against the outer wall of the inner tube 3. The airbag 4 can be compressed and deformed when the deformation tube 2 deforms, and when the deformation tube 2 begins to return to its original shape, the airbag 4 also returns to its original shape.

[0026] The support structure includes multiple support rings arranged sequentially along the axis of the inner tube 3, and each support ring includes at least two air bladders 4. Utilizing the ring-shaped air bladders 4, the deformable tube 2 can be supported by the air bladders 4 regardless of the direction in which it is compressed, thus restoring its original shape under the action of the air bladders 4 and the air bladders themselves, ensuring the reliability of the deformable tube 2.

[0027] To improve the connectivity of the flexible water pipe, the flexible water pipe also includes a connecting branch pipe 5, one end of which is connected to the flow channel and the other end of which is connected to the interior of the inner pipe 3. The flow channel and the inner pipe 3 can be interconnected, allowing some of the fluid in the flow channel to flow into the inner pipe 3, thereby increasing the flow area of ​​the flexible water pipe.

[0028] The connecting branch pipe 5 is equipped with an on / off mechanism. The on / off mechanism can control the opening and closing of the connecting branch pipe 5, thereby controlling the connection state between the flow channel and the inner pipe 3.

[0029] The inner tube 3 is equipped with a descaling agent and / or disinfectant. When the inner tube 3 is connected to the flow channel, the descaling agent and / or disinfectant in the inner tube 3 can enter the flow channel to descale or disinfect the fluid in the flow channel, thereby ensuring the quality of the fluid in the flow channel.

[0030] The deformation tube is equipped with a water quality testing mechanism, which is electrically connected to the on / off mechanism.

[0031] Alternatively, a water quality testing mechanism may be provided on the outer pipe 1, and the water quality testing mechanism may be electrically connected to the on / off mechanism.

[0032] Taking the determination of the fouling index in the flow channel as an example:

[0033] The real-time fouling index of the fluid in the flow channel is obtained by a water quality testing agency. When the real-time fouling index is higher than the preset fouling index, it indicates that descaling is required in the flow channel. At this time, the on / off mechanism is opened, and the descaling agent in the inner tube 3 enters the flow channel to perform descaling.

[0034] The inner pipe 3 can be equipped with a detection mechanism for detecting the descaling agent inside the inner pipe 3. When the detection mechanism determines that the amount of descaling agent in the inner pipe 3 is low, the hot water unit can alert the user.

[0035] Another aspect of the present invention provides a hot water unit including the aforementioned flexible water pipe.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all embodiments here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
