Description

Technical Field

[0001] This application relates to the field of bathing wastewater utilization, and in particular to a device for recycling indoor bathing wastewater. Background Technology

[0002] Bathing wastewater refers to the wastewater generated during the bathing process. It contains a large amount of low-grade heat energy. The amount of bathing wastewater discharged by the bathroom every day is relatively stable. The low-grade heat energy in the bathing wastewater can be recovered and utilized through heat exchange and recovery devices.

[0003] In related technologies, such as the invention patent with announcement number CN111043879A, a preheating device for an integrated water heater is disclosed. In use, warm water with residual heat is sprayed onto the preheating plate, and the heat is conducted to the preheating plate. At the same time, cold water enters the preheating guide path through the cold water inlet pipe for heat exchange, preheating the cold water to obtain a higher temperature. The warm water flows towards the integrated water heater through the hot water outlet pipe, fully recovering the heat from the wastewater, improving the thermal efficiency of the integrated water heater, reducing energy consumption, and reducing operating costs.

[0004] However, in practical applications, the heat exchange efficiency between the preheating plate and the cold water is low, resulting in poor heat recovery, which requires improvement. Utility Model Content

[0005] In order to improve heat transfer efficiency and thus enhance heat recovery, this application provides a device for recycling indoor bathing wastewater.

[0006] The technical solution of the indoor bathing wastewater recycling device provided in this application is as follows:

[0007] A device for recycling indoor bathing wastewater includes a base, multiple guide plates, a cold water inlet pipe, a preheated water outlet pipe, and a heat transfer pipe. The base is hollow and has a wastewater inlet trough at its upper end. The multiple guide plates are spaced apart in the base to form a snake-shaped flow channel. The cold water inlet pipe and the preheated water outlet pipe are spaced apart on one side of the base. The two ends of the heat transfer pipe are respectively connected to the cold water inlet pipe and the preheated water outlet pipe, and the heat transfer pipe is arranged along the flow channel.

[0008] By adopting the above technical solution, in practical applications, when a user stands on the base, the bathing wastewater that flows over their body enters the base through the wastewater inlet tank. The cold water required for bathing enters the heat transfer pipe through the cold water inlet pipe. The heat transfer pipe exchanges heat with the hot water in the flow channel, and then flows out through the preheated hot water outlet pipe for use, thereby realizing the recycling of bathing wastewater. In particular, because the heat transfer pipe is set along the serpentine flow channel, the contact time between the heat transfer pipe and the hot water in the flow channel is increased, and the temperature difference of the heat exchange fluid is increased, thereby improving the heat transfer efficiency and thus improving the heat recovery effect.

[0009] Preferably, the upper end of the base is provided with a plurality of guide channels spaced apart along the length of the wastewater inlet channel, and one end of the plurality of guide channels is connected to the wastewater inlet channel.

[0010] By adopting the above technical solution and setting up multiple diversion channels, the bathing wastewater can be fully recycled and guided so that it can enter the base through the wastewater inlet channel.

[0011] Preferably, the end of the guide channel that is away from the wastewater inlet channel is higher than the other end.

[0012] By adopting the above technical solution, and by setting the end of the guide channel away from the wastewater inlet channel to be higher than the other end, it is easier for bath wastewater to enter the base through the wastewater inlet channel.

[0013] Preferably, an overflow groove is provided on one side of the base.

[0014] By adopting the above technical solution and setting an overflow trough, the water level of the bathing wastewater in the base can be guaranteed.

[0015] Preferably, the recycling device further includes a spiral heating tube, which is sleeved on the heat transfer tube.

[0016] By adopting the above technical solution and setting a spiral heating tube to heat the heat transfer tube, the water flowing out of the preheated hot water outlet pipe is at a higher temperature.

[0017] Preferably, a water recycling connection port is provided on one side of the base.

[0018] By adopting the above technical solution and setting up a recycled water connection port, which is connected to the recycled water receiving device, the recycling and reuse of bathing wastewater can be realized, thereby improving the usability of the recycling device.

[0019] Preferably, the recycling device further includes a filter, which is disposed on the base and located at one end of the recycled water connection port.

[0020] By adopting the above technical solution and setting up a filter, impurities in the bathing wastewater can be filtered out, making the recycled bathing wastewater cleaner.

[0021] Preferably, the upper end of the base has a mounting hole, and the filter overlaps the mounting hole.

[0022] By adopting the above technical solution and setting installation holes to install the filter, it is easy to remove the filter, thereby facilitating the cleaning of impurities in the filter.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Because the heat transfer tubes are arranged along a serpentine flow channel, the contact time between the heat transfer tubes and the hot water in the flow channel is increased, the temperature difference of the heat exchange fluid is increased, thereby improving the heat transfer efficiency and thus improving the heat recovery effect.

[0025] 2. By setting up a recycled water connection port, which is connected to the recycled water receiving device, the wastewater from bathing can be recycled and reused, thereby improving the usability of the recycling device;

[0026] 3. By installing filters, impurities in the bathing wastewater can be filtered out, making the recycled bathing wastewater cleaner. Attached Figure Description

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0034] This application discloses a device for recycling indoor bathing wastewater.

[0035] Reference Figure 1 The recycling device includes a base 1, multiple guide plates 2, a cold water inlet pipe 3, a preheated water outlet pipe 4, and a heat transfer pipe 5. The base 1 is rectangular and hollow. A wastewater inlet trough 11 is provided at the upper end of the base 1. The wastewater inlet trough 11 is arranged along the length of the base 1 and is connected to the interior of the base 1.

[0036] Reference Figure 2 and Figure 3 The guide plate 2 is arranged in a rectangular plate shape. In this embodiment, there are four guide plates 2. The four guide plates 2 are arranged at intervals along the width direction of the base 1, and the ends of two adjacent guide plates 2 that are far apart from each other are fixedly connected to the two sides of the base 1, so that a snake-shaped flow channel 6 is formed between the four guide plates 2 and the base 1.

[0037] The cold water inlet pipe 3 and the preheated hot water outlet pipe 4 are fixedly connected to one side of the base 1 and are spaced apart along the width direction of the base 1. One end of the heat transfer pipe 5 is connected to the cold water inlet pipe 3 and the other end is connected to the preheated hot water outlet pipe 4. The heat transfer pipe 5 is located in the base 1 and is arranged along the flow channel 6.

[0038] In practical applications, users stand on base 1. After the wastewater from bathing flows over their bodies, it enters base 1 through wastewater inlet 11. Cold water for bathing enters heat transfer pipe 5 through cold water inlet pipe 3. Heat transfer pipe 5 exchanges heat with hot water in flow channel 6, and then flows out through preheated hot water outlet pipe 4 for use, thus achieving heat recovery from the wastewater. The heat transfer pipe 5 is arranged along the serpentine flow channel 6 to increase the contact time between the heat transfer pipe 5 and the hot water in flow channel 6, thereby increasing the temperature difference of the heat exchange fluid and improving heat transfer efficiency, ultimately enhancing the heat recovery effect.

[0039] Reference Figure 1 In some embodiments, the upper end of the base 1 is provided with a plurality of rectangular guide channels 12. The plurality of guide channels 12 are spaced apart along the length direction of the wastewater inlet channel 11 and one end is connected to the wastewater inlet channel 11. The bath wastewater after flowing through the body falls into each guide channel 12 to achieve full recycling of the bath wastewater and guide the bath wastewater so that the bath wastewater can enter the base 1 through the wastewater inlet channel 11.

[0040] In some embodiments, the end of the guide channel 12 away from the wastewater inlet channel 11 is higher than the end near the wastewater inlet channel 11, so that the bathing wastewater flows to the wastewater inlet channel 11 under the action of gravity, which further facilitates the bathing wastewater to enter the base 1 through the wastewater inlet channel 11.

[0041] Reference Figure 3 In some embodiments, an overflow trough 13 is provided on one side of the base 1 to ensure the water level of the bathing wastewater in the base 1. That is, when the bathing wastewater stops flowing into the base 1 from the wastewater inlet trough 11, the bathing wastewater in the base 1 is discharged through the overflow trough 13.

[0042] Reference Figure 2 In some embodiments, the recycling device further includes a spiral heating tube 7, which is sleeved on the heat transfer tube 5. The spiral heating tube 7 heats the heat transfer tube 5, so that the water flowing out of the preheated hot water outlet pipe 4 has a higher temperature.

[0043] In some embodiments, a recycled water connection port 14 is provided on the side of the base 1 away from the cold water inlet pipe 3. The recycled water connection port 14 is connected to the recycled water receiving device, which enables the recycling and reuse of bathing wastewater, thereby improving the usability of the recycling device.

[0044] In some embodiments, the recycling device further includes a filter 8, which is installed in the base 1 and located at one end of the recycled water connection port 14 to filter impurities in the bath wastewater, making the recycled bath wastewater cleaner and easier to reuse.

[0045] Reference Figure 1 and Figure 2 In some embodiments, the upper end of the base 1 is provided with a mounting hole 15, and the filter 8 is attached to the mounting hole 15 to realize the installation of the filter 8, which makes it easy to remove the filter 8 and thus facilitates the cleaning of impurities in the filter 8.

[0046] The implementation principle of this embodiment is as follows: In practical application, the user stands on the base 1. After the bathing wastewater flows over the body, it enters the base 1 through the wastewater inlet 11. The cold water required for bathing enters the heat transfer pipe 5 from the cold water inlet pipe 3. The heat transfer pipe 5 exchanges heat with the hot water in the flow channel 6, and then flows out through the preheated hot water outlet pipe 4 for use, thereby realizing the recovery and utilization of heat from the bathing wastewater. Specifically, because the heat transfer pipe 5 is arranged along the serpentine flow channel 6, the contact time between the heat transfer pipe 5 and the hot water in the flow channel 6 is increased, enhancing the temperature difference of the heat exchange fluid, thereby improving the heat transfer efficiency and thus the heat recovery effect.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
