[0026] The following combination Figures 1 to 3 , describing the embodiments of the present utility model.

[0027] According to the embodiment of the present utility model, Figure 1 and Figure 2 As shown, a hot water device is provided, which mainly includes a water heater 1, a semiconductor refrigeration plate 2 and an air supply device 3.

[0028] The water heating device described in the embodiment of the present utility model can effectively reduce steam and recover steam heat.

[0029] The water heater 1 includes but is not limited to conventional water heaters such as electric water heaters and gas water heaters. Taking an electric water heater as an example, Figure 1 As shown, the water heater 1 includes a water tank 103, and a water inlet pipe 101 and a water outlet pipe 102 connected to the water tank 103. An electric heating pipe 104 is also provided in the water tank 103. The water inlet pipe 101 inputs cold water into the water tank 103, and the water is heated by the electric heating pipe 104 and then output from the water outlet pipe 102 to provide hot water for users.

[0030] Further, if Figure 2 As shown, the semiconductor refrigeration chip 2 is a heat exchanger with a hot end and a cold end. The hot end is capable of generating heat. The hot end is used to exchange heat with the water inlet pipe 101 of the water heater 1. The air supply device 3 is used to recover indoor steam, and the air outlet of the air supply device 3 is oriented toward the cold end. The cold end can cool the steam, and when cooled, the steam liquefies into water droplets and is discharged, thereby reducing the amount of steam. At the same time, the heat of the steam is transferred from the cold end to the hot end, preheating the cold water in the water inlet pipe 101, recovering the steam heat and assisting the heating of the water heater 1.

[0031] It can be seen that the hot water device provided by the embodiment of the present invention can start the air supply device 3 and the semiconductor refrigeration plate 2 when bathing in winter. The air supply device 3 is used to transport steam to the cold end of the semiconductor refrigeration plate 2. The cold end absorbs the heat of the steam to condense the steam, thereby effectively reducing indoor steam, achieving indoor dehumidification, improving the user experience and safety, and the semiconductor refrigeration plate 2 occupies a small space. In addition, the cold end of the semiconductor refrigeration plate 2 can absorb the heat of the steam, while increasing the heat of the hot end of the semiconductor refrigeration plate 2. The hot end preheats the cold water in the water inlet pipe 101, assisting the water heater 1 in heating, thereby improving energy utilization.

[0032] It should be noted that the embodiment of the present invention does not limit the structure of the air supply device 3, and any existing structure can be selected as needed. For example, the air supply device 3 is a fan.

[0033] In one embodiment, Figure 2 As shown, the hot water device further includes a condenser 4, which is attached to the cold end, and the air outlet of the air supply device 3 faces the condenser 4. The condenser 4 is used for dehumidification. The air supply device 3 first transports steam to the condenser 4, where the steam is cooled and liquefied into water droplets.

[0034] Furthermore, in one embodiment, Figure 2As shown, the air supply device 3 is provided on the top of the condenser 4, and a drainage trough is provided at the bottom of the condenser 4. Specifically, an air inlet channel is provided on the top of the condenser 4, and the air supply device 3 is fixedly installed at the inlet of the air inlet channel to draw steam into the condenser 4.

[0035] The air supply device 3 extracts the steam in the room into the condenser 4. The steam is cooled and liquefied into water droplets at the condenser 4, and is discharged from the drainage groove at the bottom of the condenser 4 to reduce the steam in the room and improve the user experience and safety.

[0036] It should be noted that the embodiments of the present invention do not restrict the connection between the air supply device 3 and the condenser 4. The air supply device 3 and the condenser 4 can be connected using a snap-fit connection structure for quick installation, or a fastener-type connection structure to ensure connection stability. For example, the air supply device 3 is secured to the air inlet of the condenser 4 using fasteners. These fasteners can be conventional fasteners such as screws and bolts.

[0037] In one embodiment, Figure 1 As shown, the water heater further includes a controller 5, an ambient temperature sensor 6 and a flow sensor 7 electrically connected to the controller 5. The flow sensor 7 is provided on the water inlet pipe 101, and the semiconductor cooling plate 2 and the air supply device 3 are also electrically connected to the controller 5 respectively.

[0038] The flow sensor 7 is used to detect whether there is a water flow signal in the water inlet pipe 101 to determine whether the user is using the water heater 1. The ambient temperature sensor 6 is used to detect the indoor temperature and can be installed on the outside of the water tank 103.

[0039] Compared with the traditional method of using a humidity sensor to determine whether the user is using the water heater 1, the embodiment of the utility model uses a flow sensor 7 to detect the water flow signal of the water inlet pipe 101 to determine whether the user is using the water heater 1. The judgment is more accurate and the response is timely, which can avoid the semiconductor refrigeration plate 2 and the air supply device 3 from being accidentally started.

[0040] Specifically, after the flow sensor 7 detects a water flow signal for a certain period of time, the controller 5 obtains the indoor temperature detected by the ambient temperature sensor 6, which can reduce the possibility of false starts. When the indoor temperature meets the preset conditions, the controller 5 controls the semiconductor cooling plate 2 and the air supply device 3 to start.

[0041] Furthermore, a preset indoor temperature is first set. When the indoor temperature is less than or equal to the preset indoor temperature, the controller 5 controls the semiconductor cooling plate 2 and the air supply device 3 to start. For example, the preset indoor temperature is 15°C. When the indoor temperature is less than or equal to 15°C, the controller 5 controls the semiconductor cooling plate 2 and the air supply device 3 to start.

[0042] Furthermore, in one embodiment, Figure 1 As shown, the water heater further includes a first relay 13 and a second relay 14. The first relay 13 is electrically connected to the controller 5 for controlling the power on and off of the semiconductor cooling plate 2. The second relay 14 is electrically connected to the controller 5 for controlling the power on and off of the air supply device 3. The controller 5 can start and stop the semiconductor cooling plate 2 via the first relay 13 and start and stop the air supply device 3 via the second relay 14.

[0043] Furthermore, in one embodiment, Figure 2 As shown, the water heating device further includes a first temperature sensor 8 , which is disposed on the condenser 4 and electrically connected to the controller 5 .

[0044] The first temperature sensor 8 is used to detect the temperature of the condenser 4, that is, to obtain the condensation temperature. Figure 3 As shown, when the condensing temperature is lower than the first preset condensing temperature, the controller 5 controls the first relay 13 to disconnect, and the semiconductor refrigeration plate 2 stops working. When the condensing temperature rises back to the second preset condensing temperature, the controller 5 controls the first relay 13 to close, and the semiconductor refrigeration plate 2 continues to work to ensure that the temperature of the condenser 4 is maintained within the first range, thereby avoiding overcooling and frosting of the condenser 4.

[0045] In addition, the first temperature sensor 8 can also be set at the cold end of the semiconductor refrigeration chip 2 to detect the condensation temperature of the cold end of the semiconductor refrigeration chip 2 to prevent the cold end of the semiconductor refrigeration chip 2 from being overcooled and frosted.

[0046] When the flow sensor 7 does not detect a water usage signal, that is, when no water flow signal from the water inlet pipe 101 is detected within a certain period of time, it can be determined that the user has stopped using the water heater 1, and the controller 5 controls the semiconductor refrigeration plate 2 and the air supply device 3 to be turned off through the first relay 13 and the second relay 14 respectively.

[0047] Furthermore, in one embodiment, Figure 1 As shown, the water heater further includes a second temperature sensor 9, which is disposed on the water outlet pipe 102 of the water heater 1 and is electrically connected to the controller 5. The second temperature sensor 9 is used to detect the outlet water temperature of the water outlet pipe 102.

[0048] The preset indoor temperature condition can also be set based on the temperature difference between the indoor temperature and the outlet water temperature of the outlet pipe 102. For example, a preset temperature difference between the indoor temperature and the outlet water temperature of the outlet pipe 102 is first set. When the temperature difference between the indoor temperature and the outlet water temperature of the outlet pipe 102 is greater than or equal to the preset temperature difference, the controller 5 controls the semiconductor cooling plate 2 and the air supply device 3 to activate. For example, if the preset temperature difference is 23°C, and the indoor temperature is 16°C and the outlet water temperature is 40°C, the temperature difference between the indoor temperature and the outlet water temperature is 24°C. If it is greater than 23°C, the controller 5 controls the semiconductor cooling plate 2 and the air supply device 3 to activate.

[0049] It should be noted that the controller 5 can be any existing controller as needed. For example, the controller 5 can be an existing controller such as a microcontroller unit (MCU), a central processing unit (CPU), or an electronic control unit (ECU). Of course, other conventional controllers can also be selected as needed. This is not limited in the present embodiment.

[0050] Furthermore, the embodiments of the present invention do not limit the flow sensor 7 and the temperature sensors. For example, the flow sensor 7 may be a conventional structure such as a positive displacement flow meter or a turbine flow meter. Taking a turbine flow meter as an example, when a user uses the water heater 1, the water flow in the water inlet pipe 101 triggers the turbine flow meter's impeller to rotate, and the turbine flow meter's Hall element generates a square wave signal. Upon receiving the square wave signal, the controller 5 determines that there is a water flow signal. The temperature sensor may be a conventional structure such as a thermistor sensor or a thermocouple sensor.

[0051] In one embodiment, Figure 1 and Figure 2 As shown, the water heater 1 also includes a heat exchanger 10. Heat exchanger 10 is attached to the hot end. A water inlet pipe 101 passes through heat exchanger 10. Heat exchanger 10 transfers heat from the hot end to water inlet pipe 101, preheating the cold water in water inlet pipe 101. The preheated cold water is then fed into water tank 103 of water heater 1 to assist heating.

[0052] Furthermore, in one embodiment, Figure 1 As shown, the water inlet pipe 101 includes a heat exchange line 1011 and a main line 1012. The heat exchange line 1011 is arranged in a serpentine manner within the heat exchanger 10. The main line 1012 extends out of the heat exchanger 10, and the extended end of the main line 1012 is connected to the water tank 103 of the water heater 1. The heat exchange line 1011 is used to receive heat from the heat exchanger 10 to preheat the cold water in the heat exchange line 1011. The preheated cold water is then fed into the water tank 103 through the main line 1012. The serpentine arrangement of the heat exchange line 1011 within the heat exchanger 10 increases the heat transfer area, facilitates heat transfer, and further improves energy efficiency.

[0053] Furthermore, in one embodiment, Figure 1 As shown, the main line 1012 is also connected to the water outlet pipe 102 of the water heater 1 through the bypass pipe 11, and the bypass pipe 11 is provided with a mixing valve 12.

[0054] Specifically, heat exchanger 10 is used to transfer heat from the hot end to heat exchange pipe 1011. After the cold water in heat exchange pipe 1011 absorbs the heat transferred by heat exchanger 10, a portion of the preheated cold water enters the water tank 103 of water heater 1 through the extended end of main pipe 1012, while the remaining heated cold water flows directly to outlet pipe 102 through bypass pipe 11 and mixing valve 12 for user use.

[0055] The working principle of the embodiment of the utility model is as follows:

[0056] like Figure 3 As shown, when a user uses water heater 1, flow sensor 7 detects a water flow signal from water inlet pipe 101, indicating that water heater 1 is using water, and transmits this signal to controller 5. After the water flow signal persists for a predetermined period of time, controller 5 obtains the indoor temperature from ambient temperature sensor 6. If the indoor temperature meets a preset condition—that is, if the indoor temperature is less than or equal to a predetermined indoor temperature or if the temperature difference between the indoor temperature and the outlet water temperature of outlet pipe 102 is greater than or equal to a predetermined temperature difference—controller 5 controls semiconductor cooling plate 2 and air supply device 3 to turn on.

[0057] The air supply device 3 draws steam into the condenser 4, where it cools and liquefies into water droplets, which are then drained from the bottom drain of the condenser 4. Simultaneously, the condenser 4 absorbs the steam's heat and transfers it to the cold end of the semiconductor cooling chip 2. This raises the temperature of the cold end, which in turn increases the heat of the hot end of the semiconductor cooling chip 2. The heat of the steam is then transferred to the heat exchange line 1011 of the water inlet pipe 101 via the heat exchanger 10. The cold water in the heat exchange line 1011 removes the heat and is preheated. A portion of this preheated cold water flows through the main line 1012 to the water heater 1, while the remaining portion flows directly through the bypass pipe 11 and mixing valve 12 to the water outlet pipe 102 for consumption. Because the heat from the hot end is removed by the water in the water inlet pipe 101, the temperatures of both the hot and cold ends further decrease, ensuring that the condenser 4 maintains a relatively low temperature.

[0058] The condensation temperature is obtained. When the condensation temperature is lower than the first preset condensation temperature, the controller 5 controls the first relay 13 to open, and the semiconductor refrigeration plate 2 stops working. When the condensation temperature rises to the second preset condensation temperature, the first relay 13 is controlled to close, and the semiconductor refrigeration plate 2 continues to work.

[0059] After the user stops using the water heater 1 , the water flow signal detected by the flow sensor 7 disappears, that is, no water use signal of the water heater 1 is detected, and the controller 5 controls the semiconductor cooling plate 2 and the air supply device 3 to be turned off.

[0060] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The specific contents of the above-mentioned specific embodiments only express several embodiments of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
