[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] First embodiment

[0028] See also Figure 1-Figure 7 The instant electric water heater with a heating function comprises an instant electric heating device 6 for heating water, an air heating device 4 for heating air flow, an air supply duct a for guiding the flow of air flow, and a fan assembly 8 for generating negative pressure to form an air flow; the air heating device 4, the instant electric heating device 6, the fan assembly 8 and the air supply duct a are respectively arranged on the water heater body, wherein the air heating device 4, the instant electric heating device 6 and the fan assembly 8 are respectively arranged in the air supply duct a; the air inlet end of the air supply duct a is connected to the air inlet 301 on the water heater body, and the air supply duct a is connected to the air inlet 301 on the water heater body. The air outlet end of a is connected to the air outlet 302 on the water heater body; the air inlet end of the fan assembly 8 is connected to the air inlet end of the air supply duct a, and the air outlet end of the fan assembly 8 is connected to the air outlet end of the air supply duct a. When the fan assembly 8 is operating, negative pressure is generated in the air supply duct a, and the outside air enters the air supply duct a through the air inlet 301, so that airflow is formed in the air supply duct a, and the heated airflow is finally discharged through the air outlet 302; the air heating device 4, the instant electric heating device 6 and the fan assembly 8 are respectively connected to the control system, and the instant electric heating device 6 and the air heating device 4 work independently without interfering with each other.

[0029] In actual applications, the water temperature and the warm air temperature set by the user may be inconsistent; when the required water temperature is lower than the required warm air temperature, the heat generated on the surface of the instant electric heating device 6 is not enough to heat the passing airflow to the required warm air temperature, the control system will start the air heating device 4 to compensate for the required heat, so that the output warm air can meet the user's higher requirements. At this time, the air heating device 4 and the instant electric heating device 6 jointly heat the airflow. At the same heating temperature, the energy consumption of the air heating device 4 is lower than that of the traditional structure (the air heating device 4 heats alone); when the heat generated on the surface of the instant electric heating device 6 is sufficient to heat the passing airflow to the required warm air temperature, the air heating device 4 is not started, and the energy consumption can be effectively reduced while ensuring the warm air performance; when the user does not need heating but only needs hot water, the control system can start the instant electric heating device 6; when the user does not need hot water but only needs heating, the control system can start the air heating device 4 and the fan assembly 8. It can be seen that by controlling the air heating device 4 and the instant electric heating device 6 to work together, the user's different needs for heating and hot water can be met, and the heating temperature range is wide and the energy consumption is low. The heating function and the hot water function can be performed separately, so that the instant electric water heater has separate heating and hot water functions.

[0030] Furthermore, the water heater body is provided with a damper 12 for opening or closing the air outlet of the fan assembly 8, and the damper 12 is manually, electrically or automatically moved; when the damper 12 moves to position 1 (such as Figure 5As shown in FIG. 1 ), the air outlet end of the fan assembly 8 is closed; when the damper 12 moves to position 2, the air outlet end of the fan assembly 8 is opened (as shown in FIG. Figure 7 The fan assembly 8 of this embodiment is arranged at a position close to the outlet end of the air supply duct a. By setting the damper 12, the outlet end of the fan assembly 8 is closed at least when the fan assembly 8 is not in operation. On the one hand, it effectively prevents the internal structure of the fan assembly 8 from being exposed and affecting the overall appearance of the instant electric water heater. On the other hand, it effectively prevents the water vapor generated by the user when bathing when the fan assembly 8 is not in operation from entering the fan assembly 8 and affecting some electrical components.

[0031] Furthermore, the damper 12 is preferably electrically movable: the damper 12 is arranged on the water heater body in other movable modes such as sliding and rotating, and the damper 12 is electrically driven to move by the door opening and closing control component; the damper 12 arranged to rotate is described below, and the door opening and closing control component includes a door opening and closing motor 9, which is fixed to the fan assembly 8, and the motor shaft of the door opening and closing motor 9 is connected to the damper 12 through a gear assembly. When the door opening and closing motor 9 is in operation, the damper 12 is driven to reciprocate through the gear assembly, so that the air outlet end of the fan assembly 8 is opened (such as Figure 7 as shown) or closed (as Figure 5 shown);

[0032] The damper 12 can also be manually movable: the damper 12 is arranged on the water heater body in other movable ways such as sliding, rotating, etc., and the user manually drives the damper 12 to slide or rotate so that the damper 12 opens or closes the air outlet of the fan assembly 8 to achieve the purpose of controlling the damper 12; when the damper 12 moves to the set position, it can be positioned to ensure the stability of the opening or closing of the air outlet of the fan assembly 8;

[0033] The damper 12 can also be automatically moved: the damper 12 is set on the water heater body in other movable ways such as sliding and rotating. The damper 12 automatically moves to the air outlet end of the closed fan assembly 8 under the action of gravity; when the fan assembly 8 is working, the air pressure causes the damper 12 to slide or rotate to open the air outlet end of the fan assembly 8.

[0034] Furthermore, the fan assembly 8 includes a driving motor 801, a wind wheel 802 and a fan cover 803; the driving motor 801 is fixed to the side of the fan cover 803; the wind wheel 802 is rotatably arranged in the inner cavity of the fan cover 803, and the motor shaft of the driving motor 801 is connected to the wind wheel 802 to drive the wind wheel 802 to rotate; the fan cover 803 is fixed to the water heater body, the opening at the top of the fan cover 803 forms the air inlet end of the fan assembly 8, and the opening at the bottom of the fan cover 803 forms the air outlet end of the fan assembly 8, and the damper 12 is rotatably arranged at the bottom opening of the fan cover 803.

[0035] Furthermore, the water heater body is provided with an ultraviolet generating device corresponding to the outlet end of the air supply duct a, and the ultraviolet generating device is located below the fan assembly 8; the ultraviolet generating device includes a reflective cover 10, an ultraviolet light source 11 (a lamp body that can emit ultraviolet rays) and a light-transmitting component 13, and the reflective cover 10 and the light-transmitting component 13 together form a chamber for accommodating the ultraviolet light source 11, and the light-transmitting component 13 faces the outlet end of the air supply duct a, and the ultraviolet light source 11 is connected to the control system. The setting of the ultraviolet generating device enables the instant electric water heater to have a sterilization function. When the instant electric water heater confirms that there is no one around, the control system starts the ultraviolet light source 11 according to the setting to sterilize the room.

[0036] Furthermore, the air inlet end of the air supply duct a is opened on the left and right sides of the water heater body, and the air outlet end of the air supply duct a is opened at the bottom of the water heater body. It is well known that hot air will rise. The air inlet end of the air supply duct a is higher than the air outlet end. This structure can accelerate the increase of room temperature and ensure uniform room temperature.

[0037] Furthermore, the water heater body includes a translucent shell 1, and a human body sensing module 2, a display module 14 and a control panel 15 are arranged on the rear side of the translucent shell 1. The control panel 15, the display module 14 and the human body sensing module 2 are connected to the control system. The human body sensing module 2 can effectively sense whether there are people around the instant electric water heater. Through the sensing of the human body, the control system controls the ultraviolet generating device and other functional components according to the sensing results; for example, when it is in the ultraviolet sterilization mode and senses that someone is approaching, the control system turns off the ultraviolet generating device, and the ultraviolet generating device restarts after the person leaves; when it senses that someone is approaching in a dark environment, the control system starts the relevant light-emitting components to play a warning role, prevent the approaching person from colliding with the instant electric water heater protruding from the wall, or provide lighting for the approaching person. The display module 14 allows the user to view the real-time status of the instant electric water heater. The control panel 15 allows the user to control the instant electric water heater, and the control mode of the control panel 15 can be mechanical key control or touch key control.

[0038] Furthermore, the water heater body also includes an intermediate shell 3 and a supporting shell 7, the translucent surface shell 1 is arranged on the front side of the intermediate shell 3, the intermediate shell 3 is arranged on the front side of the supporting shell 7, the human body sensing module 2, the display module 14 and the control panel 15 are arranged between the translucent surface shell 1 and the intermediate shell 3; the intermediate shell 3 and the supporting shell 7 are assembled together to form an air supply duct a; a water inlet 16 and a water outlet 17 are exposed at the bottom of the water heater body, the water inlet 16 is connected to the water inlet end of the instant electric heating device 6 through a corresponding pipe body, and the water outlet 17 is connected to the water outlet end of the instant electric heating device 6 through a corresponding pipe body.

[0039] Furthermore, a heat dissipation component 5 is provided on the instant electric heating device 6. The heat dissipation component 5 effectively absorbs and centrally stores the heat on the surface of the instant electric heating device 6. When the airflow passes through the heat dissipation component 5, it exchanges heat with it, thereby achieving the purpose of heating the airflow, and the heating effect is significant.

[0040] Second embodiment
