[0001] The utility model relates to the technical field of domestic hot water reuse, in particular to a domestic hot water collection device based on waste heat recovery. Background Technique

[0002] In daily life, in order to make the cleaning more comfortable, hot water is often used for cleaning, such as kitchen water and washing water.

[0003] The used hot water still has residual temperature. If it is directly discharged, the heat will gradually dissipate over time and transmission distance. And this water with residual temperature contains heat energy, and the environmental friendliness can be effectively improved through recycling.

[0004] When taking a shower, the water consumption is relatively large, and the water temperature is generally set between 60 - 40 degrees. After the high-temperature water flow contacts the human body, it will quickly drain through the sewer. At this time, the water, due to the short contact time with air, often remains at a temperature of about 40 - 20 degrees and can be effectively utilized.

[0005] Therefore, a domestic hot water collection device based on waste heat recovery is proposed to collect and reuse the hot water generated during the shower process. Content of the Utility Model

[0006] The purpose of the utility model is to provide a domestic hot water collection device based on waste heat recovery to solve the problems raised in the above background technique.

[0011] An electromagnetic valve is installed inside the water storage cavity, and the electromagnetic valve covers above the water storage cavity water outlet.

[0012] Preferably, the corners of the diversion groove are arc-shaped corners, and anti-slip patterns are provided on the top of the recovery container.

[0013] Preferably, a filter is inserted into the water inlet of the water storage chamber, and the side of the filter facing the guide groove is flush with the bottom of the guide groove.

[0014] Preferably, the height of the water storage chamber does not exceed 10 cm, and the bottom of the water storage chamber is fixedly connected with supporting ribs, which are distributed throughout the interior of the water storage chamber to support the top of the water storage chamber.

[0015] Preferably, it also includes an auxiliary control mechanism, which includes a temperature and pressure detector and an operation panel. The temperature and pressure detector is installed inside the water storage chamber, and the operation panel is electrically connected to the temperature and pressure detector and the solenoid valve.

[0016] Preferably, the operation panel is installed on the inner wall of the dry-wet separation shower room, and the outer surface of the operation panel is provided with a waterproof cover with waterproof property, and the waterproof cover can be opened by folding.

[0029] The following specifically introduces the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0030] Please refer to Figure 1-7 , a domestic hot water collection device based on waste heat recovery, including a hot water recovery and reuse mechanism 1 and a wet and dry separation shower room 3. The wet and dry separation shower room 3 is a prior art, and its basic structure is a three-sided enclosed space with a door on the front and ventilation and auxiliary heating devices installed on the top. Therefore, it will not be elaborated here. The hot water recovery and reuse mechanism 1 is installed at the bottom of the wet and dry separation shower room 3 to collect the hot water during the shower process;

[0031] The hot water recovery and reuse mechanism 1 includes a recovery container 101, and a water storage cavity 102 is arranged inside the recovery container 101;

[0032] A flow guide groove 103 is opened at the top of the recovery container 101, a water inlet 104 of the water storage cavity is opened at the end of the flow guide groove 103, and the water inlet 104 of the water storage cavity is communicated with the water storage cavity 102;

[0033] A water outlet 106 of the water storage cavity is opened at the bottom of the recovery container 101, and the water outlet 106 of the water storage cavity is connected to the sewer pipeline;

[0034] An electromagnetic valve 107 is installed inside the water storage cavity 102, and the electromagnetic valve 107 covers above the water outlet 106 of the water storage cavity.

[0035] Through the above technical solution, a recycling container 101 is arranged below the bathroom shower head, and a water storage cavity 102 is arranged inside the recycling container 101, so that the water during the shower enters the water storage cavity 102 through the water storage cavity water inlet 104 for temporary storage. The warm water stored in the water storage cavity 102 conducts its temperature back to the inside of the dry-wet separation shower room 3 through the surface of the recycling container 101, thereby assisting in keeping the bather warm and achieving the effect of recycling waste heat;

[0036] In order to improve the heat conduction effect of the recycling container 101, the top of the recycling container 101 is made of heat-conducting metal, such as materials with good heat conduction performance and not easy to corrode like copper and stainless steel, while the periphery of the recycling container 101 is covered with heat-insulating materials, so as to reduce heat loss and make the temperature transmit directionally, and the water temperature in the water storage cavity 102 can be above 20 degrees. In winter, a temperature above 20 degrees will make people feel warm;

[0037] For example, during the shower, when applying soap or body wash, the water source is generally turned off to avoid the water sprayed by the shower head washing away the bathing substances on the body. At this time, the temperature of the whole environment will drop. Generally, the installation height of the bathroom heater is relatively high, and the light and heat radiation can basically only act on the upper body of the human body, and the lower body will still feel cold. Therefore, this device transfers heat from the bottom upwards to assist devices such as bathroom heaters in keeping the human body warm and improving the comfort during bathing;

[0038] During the installation process, this device does not need to damage the original bathroom tiles, can be directly placed on the bathroom tiles, and can be connected to the sewer pipe through a hose at the water storage cavity water outlet 106.

[0039] Specifically, the corners of the diversion groove 103 are rounded corners, and the top of the recycling container 101 is provided with anti-slip patterns.

[0040] Through the above technical solution, the edge of the diversion groove 103 is set as a rounded corner to avoid the sharp edge of the diversion groove 103 from cutting the sole of the foot when walking barefoot;

[0041] And anti-slip patterns are provided on the top of the recycling container 101 to improve the anti-slip performance during the shower, and the safety can be improved whether walking barefoot or wearing slippers.

[0042] Specifically, a filter element 105 is inserted inside the water storage cavity water inlet 104, and the side of the filter element 105 facing the diversion groove 103 is flush with the bottom of the diversion groove 103.

[0043] Through the above technical solution, the filter 105 is used to filter the hair dropped during showering to prevent the hair from entering the water storage chamber 102 and clogging the space, and the height of the side of the filter 105 is set to allow the water flow to smoothly pass through the filter 105 and enter the water storage chamber 102, and the detachable filter 105 can facilitate the cleaning of the hair accumulated in the filter 105.

[0044] Specifically, the height of the water storage chamber 102 does not exceed 10 cm, and the bottom of the water storage chamber 102 is fixedly connected with supporting ribs 108 , which are distributed throughout the interior of the water storage chamber 102 to support the top of the water storage chamber 102 .

[0045] Through the above technical solution, the amount of water used in the shower process will not be very large. Therefore, the volume of the water storage chamber 102 is set to avoid the distance between the water surface in the water storage chamber 102 and the top of the recovery container 101 being too large. When the distance between the water surface in the water storage chamber 102 and the top of the recovery container 101 is too large, the heat conduction efficiency of the warm water will be much worse.

[0046] The purpose of providing the supporting ribs 108 is to improve the safety and stability of the device. A large number of supporting ribs 108 are arranged to distribute the pressure on the top of the recovery container 101 to prevent the top of the recovery container 101 from being dented, collapsed or deformed after being subjected to force because the recovery container 101 contains a water storage chamber 102.

[0047] Specifically, the domestic hot water collection device also includes an auxiliary control mechanism 2, which includes a temperature and pressure detector 201 and an operation panel 202. The operation panel 202 has a backlight display screen. The temperature and pressure detector 201 is installed inside the water storage chamber 102. The operation panel 202 is electrically connected to the temperature and pressure detector 201 and the solenoid valve 107.

[0048] Through the above technical solution, the temperature and pressure detector 201 is set to monitor the water temperature and water volume in the water storage chamber 102, and transmit the water temperature and water volume information to the operation panel 202 for display, so that the user can intuitively understand the situation in the water storage chamber 102, and the operation panel 202 can control the solenoid valve 107 by setting the data threshold:

[0049] For example, when the water temperature is lower than 15 degrees, the solenoid valve 107 is controlled to drain water to prevent the temperature from further decreasing; or when the water in the water storage chamber 102 is almost full, the solenoid valve 107 is controlled to drain water partially, so that new warm water can be added to the inside of the water storage chamber 102 to maintain the temperature inside the water storage chamber 102 and avoid flooding;

[0050] After the bathing is completed, directly control the solenoid valve 107 through the operation panel 202 to drain the water completely, avoiding the long-term accumulation of sewage inside the water storage cavity 102.

[0051] Specifically, the operation panel 202 is installed on the inner wall of the wet-dry separation shower room 3. The outer surface of the operation panel 202 is provided with a waterproof cover 203 with waterproof properties, and the waterproof cover 203 can be opened by folding.

[0052] Through the above technical solution, the operation panel 202 is installed on the inner wall of the wet-dry separation shower room 3 for easy observation and operation during bathing, and is equipped with a waterproof cover 203 for waterproofing to protect the operation panel 202.

[0053] The material of the waterproof cover 203 is preferably transparent. When viewing the values displayed on the operation panel 202, there is no need to open the waterproof cover 203, further improving the convenience and safety of use.

[0054] Specifically, the auxiliary control mechanism 2 further includes a wiring trough 204. The wiring trough 204 is installed on the outer surface of the wet-dry separation shower room 3. The lines of the solenoid valve 107, the temperature and pressure detector 201, and the operation panel 202 are all arranged inside the wiring trough 204.

[0055] Through the above technical solution, the provided wiring trough 204 is used to protect the lines and improve the aesthetics of wiring, while the wiring trough 204 is arranged on the outside of the wet-dry separation shower room 3 to further improve safety.

[0056] During use, by setting a recycling container 101 under the bathroom shower head and arranging a water storage cavity 102 inside the recycling container 101, the water during the shower process enters the water storage cavity 102 through the water storage cavity water inlet 104 for temporary storage. The warm water stored in the water storage cavity 102 conducts its temperature back to the inside of the wet-dry separation shower room 3 through the surface of the recycling container 101, thereby assisting in keeping the bather warm and achieving the effect of recycling and reusing waste heat.

[0057] By arranging a solenoid valve 107 and a temperature and pressure detector 201 inside the water storage cavity 102 and controlling them through the operation panel 202, during the bathing process, the temperature and pressure detector 201 monitors the water temperature and water level height in the water storage cavity 102. When the water temperature is too low or after the bathing is completed, the solenoid valve 107 is controlled through the operation panel 202 to drain the water, achieving the effect of convenient use.
