The existing bathroom generally dehumidifies by a moisture absorption part or a condensation dehumidification part, the moisture absorption part removes water vapor in air flow in an adsorption mode, and the dehumidification efficiency is low; the cost of the condensing and dehumidifying part is high. The electric water heater 100 of the present invention includes a hot water unit 1, an air external circulation component for discharging indoor air to the outside or introducing outdoor air into the room, and an air internal circulation component for raising or lowering the temperature of the room, so that the electric water heater 100 can adjust the temperature of a bathroom through the air internal circulation component, provide a comfortable constant temperature bathing environment for a user, or the electric water heater 100 can discharge dirty air in the room or introduce fresh air through the air external circulation component, in addition to the basic function of supplying hot water. In addition, this electric water heater 100 can also combine air inner loop subassembly and air extrinsic cycle subassembly to carry out high-efficient dehumidification and deodorization simultaneously, can heat up the ponding in coming the bathroom and the condensate water rapid evaporation into vapor on the wall through the air inner loop subassembly to the bathroom, and through the air extrinsic cycle subassembly with the bathroom in the air escape bathroom of high humidity, thereby realize high-efficient dehumidification drying performance, improve the bathroom environment fast effectively, avoid breeding bacterium and mould, prevent to produce the peculiar smell, user experience is good.
In addition, with the miniaturization of families, the restriction of urban living space and the development trend that consumers continuously pursue high-quality living quality, the demand of miniaturized and function-integrated household appliances is increasing day by day, the electric water heater of the invention can be used for multiple purposes, can simultaneously integrate the functions of hot water, warm air, ventilation and exhaust and high-efficiency dehumidification, can well meet the consumption demand of consumers, and has stronger product competitiveness.
It should be noted that the arrangement of the air external circulation component and the air internal circulation component of the electric water heater 100 of the present invention can be varied, wherein, the embodiment in which the air external circulation component and the air internal circulation component have respective independent air channels and the air external circulation component and the air internal circulation component have a common intake air channel will be exemplified herein. The air outside circulation assembly may include a fan disposed in the outside circulation flow passage, and thus, the discharge of the indoor air to the outside or the introduction of the outdoor air to the inside may be performed by controlling a rotation direction of the fan. Hereinafter, a case where the external circulation flow passage of the air external circulation assembly is used to discharge indoor air to the outside of the room will be exemplified.
Optionally, the air inner circulation assembly may further include a temperature adjusting device disposed in the inner circulation flow passage, the temperature adjusting device including a heating device 44 for raising the temperature of the air and/or a cooling device for lowering the temperature of the air. That is, the temperature adjusting device may be one of the heating device 44 and the cooling device, or the temperature adjusting device may include both the heating device 44 and the cooling device. The heating device 44 is, for example, a PTC heater, etc., and can be heated up rapidly, and can automatically control the temperature when encountering a fan failure, and has a long service life; the refrigerating device can be, for example, a chip for refrigerating, or a refrigerating device such as a condenser. Some specific embodiments of the electric water heater 100 will be exemplified below when the temperature regulating device is the heating device 44.
In some embodiments, the outer circulation flow channel and the inner circulation flow channel are independent flow channels, the outer circulation fan 23 and the inner circulation fan 43 are independent fans, the outer circulation fan 23 is disposed in the outer circulation flow channel, and the inner circulation fan 43 is disposed in the inner circulation flow channel. As shown in fig. 1 and 3, the air internal circulation assembly includes an internal circulation fan 43, a heating device 44, and an internal circulation air inlet 41 and an internal circulation air outlet 42 respectively communicating with the indoor environment, and the internal circulation fan 43 and the heating device 44 are disposed in an internal circulation air duct between the internal circulation air inlet 41 and the internal circulation air outlet 42. The internal circulation fan 43 comprises an internal circulation motor 431 and an internal circulation wind wheel 432 driven by the internal circulation motor. After bathing is completed, accumulated water and condensed water easily exist on the floor and the wall of a bathroom, and the dehumidifying efficiency is low and the use is inconvenient because the dehumidifying efficiency is only natural air-dried or only exhaust through the air external circulation component. For this purpose, the heating device 44 is disposed in the internal circulation air duct of the air internal circulation assembly, and after the heating device 44 is powered on, the heating device can generate a large amount of heat and blow the heat to the bathroom environment through the internal circulation fan 43, that is, the heating device 44 can make the internal circulation air outlet 42 blow hot air with a temperature higher than the temperature of the bathroom environment. Thus, the accumulated water and condensate within the bathroom can be rapidly vaporized by the hot air flow of the heating device 44, and the high humidity air can be discharged outside the room through the air external circulation assembly. The electric water heater 100 of the invention can quickly dry the bathroom environment through the air external circulation component and the air internal circulation component, thereby effectively improving the dehumidification efficiency. If the user does not need to dehumidify the bathroom, the heating device 44 may not operate simultaneously with the internal circulation fan 43, that is, the internal circulation fan 43 may operate alone, and the internal circulation fan 43 may be used as a fan in hot summer to provide cool air to the bathroom.
Further, as shown in fig. 1, the air external circulation assembly may include an external circulation air inlet 21 communicating with the indoor environment, an external circulation air outlet 22 communicating with the outdoor environment, and an external circulation fan 23, the external circulation fan 23 being disposed in the external circulation duct between the external circulation air inlet 21 and the external circulation air outlet 22. The external circulation fan 23 includes an external circulation motor 231 and an external circulation wind wheel 232 driven by the external circulation motor. The external circulation fan 23 can be used in cooperation with the internal circulation fan 43 and the heating device 44 in the air internal circulation assembly for efficient dehumidification, or can not be operated simultaneously with the internal circulation fan 43 and the heating device 44 in the air internal circulation assembly, that is, the external circulation fan 23 of the air external circulation assembly can be operated alone to ventilate the bathroom. Of course, it is also possible to operate only the inner circulation fan 43 and the heating means 44 of the air inner circulation assembly without operating the outer circulation fan 23 of the air outer circulation assembly, and the air inner circulation assembly can be used to increase the temperature of the bathroom to provide the user with the proper bathing temperature in the cold weather.
Furthermore, in order to make the structure of the electric water heater 100 more reasonable and compact and be suitable for being accommodated in a narrow bathroom space, the electric water heater 100 further includes a water heater housing 3 with an internal housing cavity 31, the hot water unit 1 can be located at one end of the housing cavity 31, and the internal air circulation component and the external air circulation component are located in parallel at the other end of the housing cavity 31.
As shown in fig. 1, the hot water unit 1 is located at one lateral end of the shell chamber 31, and the air external circulation assembly and the air internal circulation assembly are vertically juxtaposed and located at the other lateral end of the shell chamber 31.
Thus, the electric water heater 100 of the present invention has various functions, reasonable and compact structure, and is suitable for use in small rooms. Of course, in addition to the above exemplary embodiments, the electric water heater 100 may be disposed in a vertical direction, and the present invention is not limited thereto.
Alternatively, referring to fig. 1, the hot water module 1 generally includes basic functional components such as a heating body 11 for heating a water source, a liner 12, a water inlet pipe 16, a water outlet pipe 14, and a sewage discharge pipe 15. The heating body 11 comprises a fixed mounting part fixedly mounted on the side wall of the inner container 12, and one end of the heating body 11 extends to the other side of the inner container 12. Since the controller 6 needs to be electrically connected to the heating body 11, the outer circulation fan 23, and the inner circulation fan 43, the fixed installation part and the air outer circulation unit and/or the air inner circulation unit may be adjacently disposed for optimizing and facilitating the wiring control, so that the wiring layout is more reasonable. In addition, the heating body 11 is arranged close to one side of the air external circulation component and one side of the air internal circulation component, so that heat dissipation can be performed on heating elements such as the heating body 11, and a protection effect can be further achieved on a control device.
Optionally, the air external circulation assembly may be disposed above the air internal circulation assembly, so that the height of the external circulation flow channel is increased, the flow channel through which the indoor air is discharged to the outside is shortened, and the exhaust efficiency of the external circulation flow channel is effectively improved. For the air internal circulation flow channel, when the indoor temperature needs to be raised, for example, hot air is output from an air outlet of the air internal circulation assembly below, the mass of the hot air is lighter than that of cold air, the hot air can naturally rise from bottom to top, the migration route of the hot air in the room is longer, the temperature in the room can be favorably regulated, and the moist and hot air can be conveniently and quickly exhausted out of the room and the environment in the bathroom can be favorably improved.
In addition, for more reasonable arrangement and installation of the inner container 12 and the air external circulation component and/or the air internal circulation component of the electric water heater 100, the housing cavity 31 may include a first end and a second end along the horizontal direction, the inner container 12 being located at one of the first end and the second end, and the air external circulation component and/or the air internal circulation component being located at the other of the first end and the second end. The electric water heater 100 of the present invention may be a dual-liner water heater, and the liner 12 includes a first liner and a second liner arranged in parallel along a vertical direction. Heating bodies 11 can be arranged in the two inner containers 12. Since the inner container 12 of the electric water heater usually needs to be pressurized and is usually configured to be a barrel shape, for an electric water heater 100 with the same volume, such as an 8L electric water heater 100, the side end space of a single 8L inner container accommodated behind the shell cavity 31 is difficult to be reasonably arranged, so that the effective use space of the side end cover seat 4 is small, that is, the mountable space of the air external circulation module 2 and the air internal circulation module 7 is small. In the electric water heater 100 with double inner containers (for example, two inner containers 12 of 4L are respectively provided), a reasonable space can be provided in the housing cavity 31 for installing the air external circulation component and the air internal circulation component, so that the overall arrangement and installation of the electric water heater 100 are more reasonable.

Thus, because the air needs to be adjusted in the inner circulation, for example, the hot air is output from the air outlet of the air inner circulation assembly below, the mass of the hot air is lighter than that of the cold air, the hot air can naturally rise from bottom to top, the migration route of the hot air in the room is longer, the temperature in the room can be adjusted, and the improvement of the environment in the bathroom is facilitated.
Alternatively, the opening of the external circulation air inlet 21 is at least partially disposed on the side wall of the electric water heater 100, and the opening of the external circulation air outlet 22 is disposed on the top wall of the electric water heater 100.
