Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to an integrated bathtub water circulation filtration system. Background Technology

[0002] With the development of the bathroom industry, people have endowed bathtubs with more functions, such as automatic water supply and drainage, automatic heating, or automatic water level detection, which are now common features. At the same time, in order to meet the different needs of people soaking in cold or hot water, integrated bathtubs with cooling or heating functions have emerged. These bathtubs not only meet various needs but also save costs.

[0003] Currently, most integrated bathtubs on the market drain the bathwater directly into the sewage pipe after bathing, resulting in waste as the water cannot be reused. Furthermore, because the bathwater cools easily, prolonged bathing requires draining the cooled water and refilling with hot water, which is inconvenient. Additionally, after use, the bathwater contains hair, dander, bacteria, and other substances, reducing water cleanliness. This prolonged water circulation not only provides a poor user experience but also increases the risk of skin infections and harms the user's health. Utility Model Content

[0004] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide an integrated bathtub water circulation filtration system, which aims to solve the problems of water waste and poor cleanliness of recycled water in the prior art. By setting up a water circulation filtration system to filter and purify the wastewater after bathing and then recycle it, water waste can be reduced.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated bathtub water circulation and filtration system includes an inlet pipe connecting an external water supply system to the bathtub inlet, an outlet pipe connecting the bathtub outlet, and a return pipe connecting the inlet and outlet pipes. A heat exchange device is installed along the flow path of the inlet pipe to separately cool or heat the water in the inlet pipe. A wastewater collection device and a wastewater purification and filtration device are installed along the flow path of the outlet pipe to filter and purify the wastewater in the outlet pipe. A pressurization device is installed along the flow path of the return pipe to pump the water in the bathtub through the return pipe to the heat exchange device for cooling or heating, so that the filtered and purified cold or hot water can be separately circulated back into the bathtub.

[0007] Preferably, the heat exchange device includes a refrigeration module, a heating module, and a heat exchange module. The refrigeration module and the heating module are connected in series on the flow path of the inlet pipe, and the refrigeration module and the heat exchange module are connected in a loop. The heating module is connected on the flow path of the return pipe and is located between the outlet end of the heat exchange module and the return pipe.

[0008] Preferably, the wastewater collection device includes a wastewater tank, a filter plate disposed inside the wastewater tank, and an activated carbon layer located between the filter plate and the wastewater tank. The wastewater tank has an inlet on one side and an outlet on the other side. Multiple filter plates are disposed and are vertically and equidistantly inserted into the wastewater tank. The activated carbon layer is evenly distributed inside the wastewater tank.

[0009] Preferably, the wastewater purification and filtration device includes an air pipe, an ejector disposed on the flow path of the air pipe, and an ozone generator located on one side of the ejector. The air pipe is disposed in parallel on the water outlet pipe. The ejector is connected to both the air pipe and the ozone generator.

[0030] The following is in conjunction with the appendix Figure 1-2 The present invention provides a more detailed description of an embodiment of an integrated bathtub water circulation filtration system.

[0031] An integrated bathtub water circulation filtration system, such as Figure 1 , 2 As shown, the system includes an inlet pipe 1 for connecting the external water supply system to the bathtub inlet, an outlet pipe 2 for connecting the bathtub outlet, and a return pipe 3 for connecting the inlet pipe 1 and the outlet pipe 2. A heat exchange device 4 is installed in the flow path of the inlet pipe 1 to separately cool or heat the water in the inlet pipe 1. A sewage collection device 5 and a sewage purification and filtration device 6 are installed in the flow path of the outlet pipe 2 to filter and purify the sewage in the outlet pipe 2. A pressurization device 7 is installed in the flow path of the return pipe 3 to pump the water in the bathtub through the return pipe to the heat exchange device 4 for cooling or heating, so that the filtered and purified cold or hot water can be separately circulated back into the bathtub.

[0032] Specifically, the working principle of the water circulation filtration system is as follows: First, bath water is pre-injected into the inlet pipe 1 through the external water supply system. The water flow first passes through the heat exchange device 4 for cooling or heating, and then into the bathtub through the inlet pipe 1. During the water injection process, the filter purifier filters the external water source. After bathing, the wastewater in the bathtub begins to be discharged into the outlet pipe 2, and the wastewater collection device 5 filters and collects the debris, hair, and other impurities contained in the wastewater. The wastewater after preliminary treatment by the wastewater collection device 5 flows into the wastewater purification and filtration device 6 for further disinfection and purification. Finally, the purified water is returned to the heat exchange device 4 through the return pipe 3 for re-cooling or heating for reuse in the bathtub.

[0033] In this embodiment, as Figure 2 As shown, the heat exchange device 4 includes a refrigeration module 41, a heating module 42, and a heat exchange module 43. The refrigeration module 41 and the heating module 42 are connected in series in the flow path of the water inlet pipe 1, and the refrigeration module 41 and the heat exchange module 43 are connected in a loop. The heating module 42 is connected in the flow path of the return pipe 3 and is located between the heat exchange module 43 and the water outlet of the return pipe 3.

[0034] Specifically, since everyone's needs are different, some people like to take cold or ice water baths, while others prefer hot baths. Therefore, this utility model adds a heat exchange device 4 to the bathtub, and uses the cooling module 41 and heating module 42 in the heat exchange device 4 to produce cold and hot water. When water is injected into the bathtub, in order to provide cold or hot water according to the user's needs, when cold water is needed, the water inlet pipe 1 starts to inject water into the cooling mode, and the cooling work is quickly completed under the action of the cooling module 41. Then, after being purified by the filter, the water flows into the bathtub. Then, the wastewater after use is discharged out through the water outlet pipe 2, and after being filtered and purified, it flows back to the heat exchange device 4 through the return pipe 3 for reuse.

[0035] In this embodiment, the sewage collection device 5 includes a sewage tank 51, a filter plate 52 disposed in the sewage tank 51, and an activated carbon layer 53 located between the filter plate 52 and the sewage tank 51. The sewage tank 51 has an inlet on one side and an outlet on the other side. Multiple filter plates 52 are disposed and vertically and equidistantly inserted into the sewage tank 51. The activated carbon layer 53 is evenly distributed inside the sewage tank 51.

[0036] Specifically, after the bathtub is used, the wastewater needs to be discharged. The wastewater collection device 5 is used to collect the wastewater and perform simple preliminary filtration to remove hair, debris and other impurities. During the preliminary filtration process, the wastewater is collected by the wastewater tank 51 and the activated carbon layer 53 inside the tank quickly adsorbs floating matter and impurities in the wastewater. Then, it is filtered by the multi-layer filter plate 52, so that the preliminarily filtered and purified wastewater flows into the wastewater purification filter device 6 through the filter outlet pipe 22 for further filtration and purification.

[0037] In this embodiment, the wastewater purification and filtration device 6 includes an air pipe 61, an ejector 62 disposed on the flow path of the air pipe 61, and an ozone generator 63 located on one side of the ejector 62. The air pipe 61 is disposed in parallel on the water outlet pipe 2. The ejector 62 is connected to the air pipe 61 and the ozone generator 63 respectively.

[0038] Specifically, the air duct 61 can introduce airflow into the pre-filtered wastewater, and the jet nozzle 62 sprays the wastewater into the ozone generator 63 for sterilization and disinfection. The ozone generator 63 releases ozone factors, which combine with and disinfect bacteria in the wastewater, thereby improving the purity of the purified wastewater. The filtered and purified water is then recycled through the return water pipe to save water resources.

[0039] To control the direction of water flow, both the inlet pipe 1 and the return pipe 3 are equipped with diversion valves 8 to control the water flow direction. These valves allow cold and hot water to circulate separately, saving energy and improving the efficiency of the heat exchanger 4. Simultaneously, to control the water flow, the outlet pipe 2 is equipped with a solenoid valve 9 to stop the flow. This valve automatically controls the water flow direction based on the inlet and outlet water flow and automatically selects whether to use a water circulation filtration system in different application scenarios, thus expanding its applicability.

[0040] In this embodiment, the water inlet pipe 1 includes a front water inlet pipe 11 and a rear water inlet pipe 12. One end of the front water inlet pipe 11 is connected to an external water supply system, and the other end is connected to the refrigeration module 41. A water purifier 13 is installed on the front water inlet pipe 11. One end of the rear water inlet pipe 12 is connected to the water inlet of the bathtub, and the other end is connected to the refrigeration module 41 and the heating module 42 separately through a two-way three-way pipe.

[0041] Specifically, the front water inlet pipe 11 is used to connect with the external water source to facilitate timely replenishment of water and avoid slow flow or insufficient circulating and purified water, which would affect the use of the bathtub. The rear water inlet pipe 12 can supply water to the bathtub independently with either the cooling module 41 or the heating module 42, without affecting each other and improving water inlet efficiency.

[0042] In this embodiment, the water outlet pipe 2 includes a sewage outlet pipe 21 and a filtered water outlet pipe 22. One end of the sewage outlet pipe 21 is connected to the drain outlet of the bathtub, and the other end is connected to the inlet of the sewage tank 51. The filtered water outlet pipe 22 is connected between the sewage tank 51 and the air pipe 61, and a hair collector 23 is provided on the filtered water outlet pipe 22.

[0043] Specifically, the front end of the sewage outlet pipe 21 is connected to the drain outlet at the height of the bathtub, which is used to quickly collect and purify the sewage after use in the bathtub. Then, it is discharged through the filter outlet pipe 22 to the sewage purification filter device 6 for secondary disinfection and purification. Finally, the hair collector 23 is used to collect the impurities contained in the sewage after the initial filtration and secondary filtration, so as to facilitate subsequent cleaning and replacement.

[0044] In this embodiment, the return pipe 3 includes a cold water return pipe 31 and a hot water return pipe 32. One end of the cold water return pipe 31 is connected to the refrigeration module 41, and the other end is connected to the ozone generator 63. One end of the hot water return pipe 32 is connected to the heating module 42, and the other end is connected to the ozone generator 63. A temperature sensor 33 for detecting water temperature is provided at the connection between the hot water return pipe 32 and the cold water return pipe 31.

[0045] Specifically, after the cold or hot water wastewater in the bathtub is filtered and purified, the diversion valve 8 automatically opens to control the direction of water flow, detected by the temperature sensor 33. The filtered cold water is recirculated back to the cooling module 41 through the cold water return pipe 31 for use in the bathtub, while the filtered hot water is recirculated back to the heating module 42 through the hot water return pipe 32, reducing heat exchange time and improving heating efficiency. The separately designed return pipe 3 better utilizes the energy of both cold and hot water, thereby reducing energy waste.

[0046] The working principle of this utility model:

[0047] First, bathing water is pre-filled into the front-end inlet pipe 11 through the external water supply system. The water flows through the heat exchanger 4 for cooling or heating, and then into the bathtub through the rear-end inlet pipe 12. During the water filling process, the filter purifier filters the external water source. After bathing, the wastewater in the bathtub begins to be discharged into the outlet pipe 2. At this time, the solenoid valve 9 on the wastewater outlet pipe 21 opens, and the wastewater enters the wastewater tank 51. Under the action of the filter plate 52 and the activated carbon layer, the debris, hair, and other impurities contained in the wastewater are filtered and collected. Among them, the hair will be intercepted by the hair collector 23 and then discharged through the wastewater collection device 5. After treatment, the wastewater flows into the wastewater circulation and purification device through the filter outlet pipe 22. Finally, it is sterilized and disinfected by the air pipe 61, the jet injector and the ozone generator 63. The purified water is then returned to the heat exchange device 4 through the return pipe 3 for recycling. Since the wastewater is either cold or hot water, the temperature of the purified water is detected by the temperature sensor 33. Under the action of the pressurization device 7, the cold water is returned to the refrigeration module 41 through the cold water return pipe 31 for re-cooling; the hot water is returned to the heating module 42 through the hot water return pipe 32 for re-heating. Then, the cold or hot water that has reached the required temperature is returned to the bathtub for recycling through the downstream inlet pipe.

[0048] In summary, the integrated bathtub water circulation filtration system of this utility model can filter and purify the wastewater after rinsing and then recycle it to reduce water waste. By optimizing the water circulation pipeline and setting up a wastewater collection device 5 and a wastewater purification and filtration device 6 to filter and clean the used cold or hot water, the system avoids the problem of reduced water cleanliness due to the presence of hair, dander, bacteria, and other substances during water circulation, thereby reducing the possibility of users contracting skin diseases and ensuring the health of users.
