Description

Technical Field

[0001] This utility model relates to the technical field of heat recovery devices, and in particular to a heat recovery device that is easy to disassemble and clean. Background Technology

[0002] In shampoo and flush systems used in barbershops and beauty salons, a heat recovery device is installed at the shampoo basin's inlet. This device recovers heat from the wastewater while supplying water, achieving energy savings. The heat recovery device typically consists of a drain housing and heat exchange coils fixed inside. Over time, hair and other debris can accumulate in shampoo and flush systems, and dirt can build up inside the heat exchange coils, affecting heat exchange efficiency. Therefore, when cleaning is needed, the heat exchange coils are difficult to disassemble and clean because they are fixed inside the drain housing, leading to increased maintenance costs and low efficiency.

[0003] To address the aforementioned problems, Chinese Patent CN214250638U discloses a replaceable inner core and a heat recovery device including the same. The replaceable inner core includes: an inner shell with an internal cavity for accommodating the heat exchange inner core; an outer shell with an external cavity for accommodating the inner shell; and a locking ring detachably connected to the outer shell and used to define the relative position of the inner shell and the outer shell. At least one locking block is provided on the outer surface of the locking ring, and a locking groove is provided on the inner surface of the outer shell to cooperate with the locking block. The locking block enters or exits the locking groove to lock or unlock the relative position of the locking ring and the outer shell. When the locking ring is screwed into the outer shell, the locking block can enter or exit the locking groove, thereby locking or unlocking the relative position of the locking ring and the outer shell. The locking block and locking groove work together to switch between locked and unlocked states. When replacing the heat exchanger core, it is switched to the unlocked state; during heat exchange operations, it is switched to the locked state to prevent cold water from entering the heat exchanger core and causing it to move. However, this replaceable core and its heat recovery device use a locking ring, which detachably connects to the outer shell to secure the inner shell. During installation, the locking ring must be screwed into the outer shell before the locking block can enter or exit the locking groove to lock or unlock the relative position of the locking ring and the outer shell. This operation is complex, requiring the locking ring and the outer shell to be aligned before screwing it in. The disassembly and assembly are not efficient and hinder the cleaning and maintenance of the heat exchanger core. Utility Model Content

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] like Figures 1 to 6 As shown, a heat recovery device that is easy to disassemble and clean is mainly used in the mounting port of the basin of a shampoo and rinse equipment in hair salons or beauty parlors. Of course, this easy-to-disassemble and clean heat recovery device can also be applied to other fields; the mounting port can be the mounting port of a washbasin in a shower room, the mounting port of a kitchen sink, or other areas where application is desired. In this embodiment, the application of this easy-to-disassemble and clean heat recovery device is mainly described in the context of its application in the mounting port of a shampoo and rinse equipment in hair salons or beauty parlors.

[0033] This easily disassembled and cleanable heat recovery device includes a lower water housing 1, a heat exchange core assembly 2, and an elastic support 3. The heat exchange core assembly 2 is fitted and embedded within the lower water housing 1 to exchange and recover heat from wastewater. The elastic support 3 is connected to the upper end of the heat exchange core assembly 2 for fastening and fixing, preventing the heat exchange core assembly 2 from loosening or slipping out, and ensuring the stability of the heat exchange core assembly 2 within the lower water housing 1. The inner wall of the lower water housing 1 is provided with a locking groove 11 that can be fitted and fastened to the elastic support 3; when the heat exchange core assembly 2 is fitted and embedded within the lower water housing 1, the elastic support 3 fastens into the locking groove 11 to secure the heat exchange core assembly 2 within the lower water housing 1.

[0034] This easily disassembled and cleaned heat recovery device combines a lower water housing 1, a heat exchange core assembly 2, and an elastic support 3. A locking groove 11 is provided on the inner wall of the lower water housing 1, which cooperates with the elastic support 3. When the heat exchange core assembly 2 is fitted into the lower water housing 1, the elastic support 3 snaps into the locking groove 11 to secure the heat exchange core assembly 2 within the lower water housing 1, preventing it from loosening and slipping out. This ensures the stability of the heat exchange core assembly 2 within the lower water housing 1 and contributes to stable heat recovery. When it is necessary to disassemble the heat exchange core assembly 2 from the lower water housing 1, the elastic support 3 is disengaged from the locking groove 11, allowing the entire heat exchange core assembly 2 to be removed for cleaning. This design allows for easy and quick disassembly and cleaning of the heat exchange core assembly 2, facilitating cleaning and maintenance, reducing maintenance costs. Furthermore, it is simple to operate, requiring no complex tools or procedures; users can complete disassembly and assembly with simple manual operation, improving ease of use.

[0035] In this embodiment, preferably, there are two elastic support members 3. This embodiment uses two elastic support members 3 as an example for explanation. The number of corresponding locking grooves 11 is also increased accordingly. The number of both elastic support members 3 and locking grooves 11 is designed to be two, which can be distributed on the left and right sides of the upper end of the heat exchange inner core assembly 2. This can better enhance the stability of the heat exchange inner core assembly 2 in the lower water housing 1 and prevent the heat exchange inner core assembly 2 from loosening due to water pressure impact. Of course, the number of elastic support members 3 and locking grooves 11 is not limited to this. They can also be one, three, or four, and the number can be reasonably designed according to the requirements.

[0036] In this embodiment, the elastic support 3 is swayably connected to the upper end of the heat exchange inner core assembly 2 and can swing relative to the heat exchange inner core assembly 2 in the vertical direction. When the heat exchange inner core assembly 2 is fitted into the drain housing 1, the elastic support 3 swings and snaps into the locking groove 11 to fix the heat exchange inner core assembly 2 in the drain housing 1. The elastic support 3, as a swinging structure, swings flexibly to fix the heat exchange inner core assembly 2. This design not only simplifies the installation and disassembly process but also greatly improves the user experience. The user only needs to gently swing the elastic support 3, which swings and snaps into the locking groove 11 to fix the heat exchange inner core assembly 2 in the drain housing 1, preventing the heat exchange inner core assembly 2 from loosening and slipping out, and ensuring the stability of the heat exchange inner core assembly 2 in the drain housing 1. When the elastic support 3 is swayed out of the locking groove 11, the heat exchange inner core assembly 2 can be quickly removed for cleaning by swinging the elastic support 3.

[0037] To further optimize the elastic top support 3, it is designed as a rod-shaped handle. The elastic top support 3 not only functions as a swinging structure to secure the heat exchanger core assembly 2, but also cleverly acts as a rod-shaped handle, allowing for easy lifting and swinging to facilitate the removal of the heat exchanger core assembly 2. This design simplifies the installation and disassembly process and significantly enhances the user experience. When the elastic top support 3 functions as a rod-shaped handle, the entire heat exchanger core assembly 2 can be quickly removed for cleaning. In other words, the elastic top support 3 enables rapid fixing and release of the heat exchanger core assembly 2 without the need for complex tools or cumbersome steps, facilitating quick assembly and disassembly, cleaning, and maintenance, and reducing maintenance costs. Moreover, the flexible swinging mechanism of the elastic top support 3 not only improves installation efficiency but also reduces the risk of damage due to improper operation, ensuring a smooth and safe installation process.

[0038] Specifically, the elastic top support 3 includes a rotating shaft portion 31, a bent connecting rod portion 32, and a top support rod portion 33; the top support rod portion 33 can be adapted to and fastened to the locking groove 11; both ends of the top support rod portion 33 are respectively connected to one end of the two bent connecting rod portions 32; the other end of each bent connecting rod portion 32 is connected to a rotating shaft portion 31; the upper end of the heat exchange inner core assembly 2 is provided with two connecting holes for rotatably installing the two rotating shaft portions 31. By combining the rotating shaft portion 31, the bent connecting rod portion 32, and the top support rod portion 33, the two rotating shaft portions 31 can be rotatably installed in the connecting holes, allowing the bent connecting rod portion 32 and the top support rod portion 33 to swing flexibly. This not only makes the elastic top support 3 a part of fixing the heat exchange inner core assembly 2, but also cleverly acts as a handle, providing a lifting function and allowing for flexible swinging, making it convenient to remove the heat exchange inner core assembly 2. Preferably, the top support rod 33 has an arc-shaped rod structure, which allows it to swing and snap into the locking groove 11 more effectively to secure the heat exchange inner core assembly 2 within the lower water housing 1. This reduces the contact area and makes it easier to disengage from the locking groove 11. For the shape of the bent connecting rod 32, a combination of ease of use and aesthetically pleasing curves is preferable. Of course, the shapes of the bent connecting rod 32 and the top support rod 33 can also be designed according to specific requirements.

[0039] Preferably, the top support rod 33, the two bent connecting rods 32, and the two rotating shafts 31 are integrally formed. This design of the elastic top support 3 provides structural stability and facilitates production. The elastic top support 3 can be a conventionally used metal or plastic part.

[0040] In this embodiment, the heat exchange inner core assembly 2 includes a perforated support cylinder 21 and a heat exchange coil 22; the heat exchange coil 22 is embedded in the perforated support cylinder 21; the perforated support cylinder 21 is adapted to be embedded in the drain housing 1; the elastic support members 3 are all located on the upper end of the perforated support cylinder 21. The perforated support cylinder 21 adopts a perforated hole design, that is, the outer wall of the perforated support cylinder 21 has perforations, which facilitates water flow down to the bottom of the drain housing 1 and avoids water accumulation. The heat exchange coil 22 can perform heat exchange, better realize energy transfer and conversion, and help recover the heat of hot wastewater. By designing the perforated support cylinder 21 and the heat exchange coil 22 to form the heat exchange inner core assembly 2, the heat exchange coil 22 is better positioned and installed in the perforated support cylinder 21, forming an integral structure, which is convenient to remove from the drain housing 1 and facilitates disassembly and cleaning.

[0041] Preferably, the outer wall of the perforated support cylinder 21 is provided with a strip-shaped locking groove 211 extending upwards from its bottom end; the inner wall of the drain housing 1 is provided with a locking part 12 that matches the strip-shaped locking groove 211. By providing the mutually engaging and locking strip-shaped locking groove 211 and locking part 12, on the one hand, it is convenient to align and install the heat exchange inner core assembly 2 as a whole into the drain housing 1, improving installation efficiency; on the other hand, it can stably install the heat exchange inner core assembly 2 into the drain housing 1.

[0042] In this embodiment, to further enhance the stable installation of the heat exchange core assembly 2 inside the lower water housing 1 and prevent the heat exchange core assembly 2 from loosening under water pressure during water inlet and outlet, the bottom end of the lower water housing 1 has a drain connector 13, a water inlet connector 14, and a water outlet connector 15 connected to its inner cavity; the bottom end of the vented support cylinder 21 is provided with an inner drain pipe section 212 adapted to be embedded in the drain connector 13, and a water inlet mounting port 213 and a water outlet mounting port 214 corresponding to the positions of the water inlet connector 14 and the water outlet connector 15, respectively; the lower end of the heat exchange coil 22 has a water inlet pipe section 221 that passes through the water inlet mounting port 213 and is embedded in the water inlet connector 14, and a water outlet pipe section 222 that passes through the water outlet mounting port 214 and is embedded in the water outlet connector 15. By setting a drain connector 13, a water inlet connector 14, and a water outlet connector 15 on the lower water housing 1, and setting an inner drain pipe 212, a water inlet installation port 213, and a water outlet installation port 214 on the bottom end of the vented support cylinder 21, the heat exchange inner core assembly 2 and the lower water housing can be quickly positioned and installed, further enhancing the stability of the heat exchange inner core assembly 2 in the lower water housing 1 and preventing the heat exchange inner core assembly 2 from loosening under water pressure when water enters or exits.

[0043] Preferably, both the inlet pipe section 221 and the outlet pipe section 222 are fixed to the bottom end face of the drain support cylinder 21 by a locking clamp assembly 4. The locking clamp assembly 4 includes a first clamp 41, a second clamp 42, and screws. The first clamp 41 and the second clamp 42 are adapted to clamp the inlet pipe section 221 or the outlet pipe section 222 and are both fixed to the bottom end face of the drain support cylinder 21 by screws. By first clamping the inlet pipe section 221 or the outlet pipe section 222 with the first clamp 41 and the second clamp 42, the inlet pipe section 221 or the outlet pipe section 222 is tightened and fixed. Then, the connection between the first clamp 41, the second clamp 42 and the drain support cylinder 21 is achieved by screws. This can better achieve rapid positioning and installation between the heat exchange core assembly 2 and the lower water housing 1, further enhance the stability of the heat exchange core assembly 2 in the lower water housing 1, and prevent the heat exchange core assembly 2 from loosening under the action of water pressure when water enters or exits.

[0044] Preferably, the bottom end face of the lower water housing 1 is provided with a positioning groove 16 for installing the locking assembly 4. After the locking assembly 4 locks the water inlet pipe 221 or the water outlet pipe 222, the locking assembly 4 protrudes out of the bottom end face of the lower water housing 1, and then the locking assembly 4 is positioned and installed in the positioning groove 16, which reduces the space occupied by the locking assembly 4. At the same time, it is beneficial to realize the stable installation of the heat exchange inner core assembly 2 in the lower water housing 1.

[0045] In summary, this utility model embodiment provides a heat recovery device that is easy to disassemble and clean. The device includes a lower water housing 1, a heat exchange core assembly 2, and an elastic support 3. The heat exchange core assembly 2 is fitted and embedded within the lower water housing 1 to exchange and recover heat from wastewater. The elastic support 3 is connected to the upper end of the heat exchange core assembly 2 for fastening and fixing, preventing the heat exchange core assembly 2 from loosening and slipping out, and ensuring the stability of the heat exchange core assembly 2 within the lower water housing 1. The inner wall of the lower water housing 1 is provided with a locking groove 11 that can be fitted and fastened to the elastic support 3. When the heat exchange core assembly 2 is fitted and embedded within the lower water housing 1, the elastic support 3 fastens into the locking groove 11 to fix the heat exchange core assembly 2 within the lower water housing 1.
