FIELD OF THE INVENTION

[0001] The present invention relates to the technical field of smart households, and in particular, to a smart air-heating bathroom heater. BACKGROUND OF THE INVENTION

[0002] An air-heating bathroom heater, as a tool in a bathroom for air exchanging, lighting, and rising an indoor temperature, has been applied in a lot of families. Refer to FIG. I, which is a schematic structural diagram of an existing air-heating bathroom heater. The air-heating bathroom heater includes: a main case 1, a machine cover 2, a heating component 3, a first ventilating fan 4, a second ventilating fan 5, an air vent 6, and an exhaust fence 7. The machine cover 2 is covered at an upper end of the main case 1. The first ventilating fan 4 and the second ventilating fan 5 are embedded on an upper end surface of the main case 1. The air vent 6 is provided at a side wall of the main case 1, and is in communication with the first ventilating fan 4. The machine cover 2 is provided with a suction hole 21. When the air-heating bathroom heater is used for air exchange, the first ventilating fan 4 sucks indoor air by using the suction hole 21, and discharges the indoor air to the outdoor by using the air vent 6. The heating component 3 is embedded on the upper end surface of the main case 1. A heat dissipation hole 22 is provided at a position on the machine cover 2 and corresponding to the heating component 3. The exhaust fence 7 is disposed within the heat dissipation hole 22. The heating component 3 is in communication with the second ventilating fan 5. When the air-heating bathroom heater is used to increase an indoor temperature, the second ventilating fan 5 sucks the indoor air that is then heated up by the heating component 3, and discharges the same through the exhaust fence 7 of the heat dissipation hole 22. In this way, the indoor air may be cyclically heated up.

[0003] However, the exhaust fence 7 of the existing air-heating bathroom heater usually guides a ventilation direction to be vertical to the ground. If a human body stands below or nearby the exhaust fence 7, wind may be directly blown to the human body. Discomfort may be caused to the human body because the wind is directly blown to the human body. Specifically, if 26 01 21 a user has not yet get dressed just after a bath, moisture on the human body is evaporated as hot air expelled from the exhaust fence 7 is directly blown to the human body, so that it may cause discomfort to the user.

[0025] Refer to FIG. 2, an embodiment of this application provides a smart air-heating bathroom heater, which includes: a main case 1, a machine cover 2, a restriction component 8, a first exhaust component 9, a first driving member 10, and a primary controller 11.

[0026] Refer to FIG. 3, and FIG. 3 is a schematic structural diagram of a main case without installation of a first exhaust component. A hot air exhaust vent 111 is disposed on an upper end surface of the main case 1, and the hot air exhaust vent 111 is disposed above a heating component 3. Indoor air, after being heated by the heating component 3, is discharged to a heat dissipation hole 22 through the hot air exhaust vent 111.

[0027] The restriction component 8 is disposed around an upper end of the hot air exhaust vent 111, to isolate hot air outputted by the hot air exhaust vent 111 from a first ventilating fan 4 and a second ventilating fan 5. In this way, it prevents the first ventilating fan 4 and the second ventilating fan 5 from directly sucking the hot air outputted by the hot air exhaust vent 111, which leads to wastes of energy. The restriction component 8 includes a restriction plate or a restriction box. An upper end surface of the hot air exhaust vent Illis located within a region enclosed by the restriction component 8.

[0028] Refer to FIG. 4, and FIG. 4 is a top view of a first driving member and a first exhaust component. The first driving member 10 is connected to the first exhaust component 9, to control a rotation angle of the first exhaust component 9.

[0029] The first exhaust component 9, altering an angle of the hot air inputted from the hot air exhaust vent 111 by altering an angle of itself, may prevent the hot air from being directly blown to the human body.

[0030] Particularly, when the restriction component 8 is a restriction plate, the first driving member 10 is located within a same space with the first ventilating fan 4 and the second 26 01 21 ventilating fan 5. Particularly, when the restriction component 8 is a restriction box, the first driving member 10 may be placed inside the restriction box, such that the first driving member 10 is located in a space different from that of the first ventilating fan 4 and the second ventilating fan 5. Thus, the first ventilating fan 4 and the second ventilating fan 5 would not affect operation of the first driving member 10 during operation. In addition, a lower end of the restriction box may be in communication with the main case 1.

[0031] The first exhaust component 9 is disposed within a region enclosed by the restriction component 8.

[0032] The machine cover 2 is provided with a heat dissipation hole 22, where a side wall of the heat dissipation hole 22 is in an obtuse angle to a lower end surface of the machine cover 2; the side wall of the heat dissipation hole 22 is sloping; and an area of a lower end surface of the heat dissipation hole 22 is smaller than that of an upper end surface.

[0033] An edge of a lower end of the heat dissipation hole 22 matches with an upper end of the restriction component 8. As the edge of the lower end of the heat dissipation hole 22 is closely attached to the upper end of the restriction component 8, the hot air whose direction is altered by the first exhaust component 9 is discharged from the heat dissipation hole 22.

[0034] The side wall of the heat dissipation hole 22 is provided thereon with a first infrared sensor 221 and a second infrared sensor 222 whose detection directions are opposite to each other.

[0035] As the detection directions of the first infrared sensor 221 and the second infrared sensor 222 are opposite to each other, a relative position of the human body in respect to the heat dissipation hole 22 may be thus determined.

[0036] The primary controller 11 is connected to the first driving member 10, so as to control the first driving member 10 to move or cease. When the first driving member 10 is ceased, the first exhaust component 9 also ceases rotating.

[0037] The primary controller 11 may be disposed inside the main case 1. When the restriction component 8 is a restriction box, the primary controller 11 may also be disposed inside the restriction box.

[0038] The first infrared sensor 221 and second infrared sensor 222 are connected to the primary controller 11, to detect a relative position of a user in respect to the heat dissipation hole 26 01 21 22, so that the primary controller 11 controls the first driving member 10 to drive the first exhaust component 9 to alter the rotation angle thereof, to enable the hot air discharged from the heat dissipation hole 22 to be blown to a position opposite to the human body. For example, when the human body is at a left side of the heat dissipation hole 22, the first driving member 10 drives the first exhaust component 9 to rotate rightwards, thus the hot air may be prevented from being directly blown to the human body.

[0039] The first infrared sensor 221 and the second infrared sensor 222 transfer the detected position of the human body to the primary controller 11, and the primary controller 11 controls rotation of the first driving member 10.

[0040] As an embodiment, as shown in FIG. 2 and FIG. 4, the first exhaust component 9 includes a plurality of exhaust plates 91 and rotating shafts 911 disposed on the exhaust plates 91.

[0041] The rotating shaft 911 passes through the exhaust plate 91, and the exhaust plate 91 is driven by the rotating shaft 911 to enable the rotation of the exhaust plate 91. In particular, a cross section of the exhaust plate 91 may be in a cuboid shape.

[0042] A connection line from a center of the first infrared sensor 221 to a center of the second infrared sensor 222 is perpendicular to an axial center line of the exhaust plate 91.

[0043] Since the exhaust plate 91 rotates around the rotating shaft 911, a position of the human body in a direction perpendicular to the rotating shaft 911 needs to be determined by the first infrared sensor 221 and the second infrared sensor 222. In this way, it is possible to enable rotation of the exhaust plate 91 towards a direction without person after rotating.

[0044] As an optional implementation, as shown in FIG. 5, FIG. 5 is a side view of a first driving member. The first driving member 10 includes a first driving gear 101, a first motor 102, and a first driven gear 103, a synchronization toothed belt 104, and a fastening wheel 105 that are connected to the rotating shaft 911.

[0045] An output shaft of the first motor 102 is connected to the first driving gear 101, both the first driving gear 101 and the first driven gear 103 are meshed with an inner ring of the synchronization toothed belt 104, the first driving gear 101 is disposed at an end of the inner ring of the synchronization toothed belt 104, and the fastening wheel 105 abuts against an outer ring of the synchronization toothed belt 104. 26 01 21

[0046] Specifically, each rotating shaft 911 is correspondingly connected to a first driven gear 103. The first motor 102 provides power for the first driving gear 101, and then the first driving gear 101 drives the synchronization toothed belt 104 to move. Meanwhile, the first driven gear 103 disposed at the synchronization toothed belt 104 rotates, so that the first driven gear 103 enables rotation of the exhaust plate 91, that passes through the rotating shaft 911. The fastening wheel 105 may avoid loosening of the synchronization toothed belt 104, and may better assist rotation of the synchronization toothed belt 104.

[0047] As an optional implementation, as shown in IFG. 6, FIG. 6 is a top view of another first driving member and another first exhaust component according to an embodiment of this application. The first driving member 10 includes a driving shaft 106, a second driving gear 107, a second driven gear 108, and a first bevel gear 109, a second bevel gear 110, and a second motor 112 that are connected to the rotating shaft 911.

[0048] An output shaft of the second motor 112 is connected to the second driving gear 107.

[0049] The second driving gear 107 is meshed with the second driven gear 108, the driving shaft 106 passes through the second driven gear 108 and the second bevel gear 110, and the second bevel gear 110 is meshed with the first bevel gear 109.

[0050] In this embodiment, each rotating shaft 911 is correspondingly connected to a first bevel gear 109. The second motor 112 provides power for the second driving gear 107. The second driving gear 107 drives the second driven gear 108 to rotate, and the second driven gear 108 enables the driving shaft 106 to rotate, so that the second bevel gear 110 passed through by the driving shaft 106 is rotated. Because the second bevel gear 110 is meshed with the first bevel gear 109, the first bevel gear 109 drives the rotating shaft 911 to rotate, so as to enable the exhaust plate 91 to rotate.

[0051] As an optional implementation, the machine cover 2 is provided thereon with a temperature sensor 23; the temperature sensor 23 and the heating component 3 are respectively connected to the primary controller 11; and the temperature sensor 23 detects an indoor temperature, so that when the indoor temperature is higher than a temperature threshold, the primary controller 11 controls the heating component 3 to cease.

[0052] The temperature sensor 23 detects the indoor temperature, and transmits the detected indoor temperature to the primary controller 11. The primary controller 11 may determine 26 01 21 whether an air temperature is higher than the temperature threshold. If the air temperature is higher than the temperature threshold, it indicates that the indoor temperature is relatively high and is not suitable for the human body, and the primary controller 11 controls the heating component 3 to cease. The temperature sensor 23 monitors the indoor temperature in a real time manner. After the heating component 3 is ceased, if the indoor temperature is lower than a threshold, it is determined by use of the first infrared sensor 221 or the second infrared sensor 222 whether there is a person in the room at this time. If there is a person, the heating component 3 is controlled to start operating by using the primary controller 11 again, so as to keep the indoor temperature to be suitable for the activity of person.

[0053] As an optional implementation, the machine cover 2 is further provided thereon with a humidity sensor 24. The humidity sensor 24 and the first ventilating fan 4 are connected to the primary controller 11. The humidity sensor 24 detects indoor humidity, so that when the indoor humidity is higher than a humidity threshold, the primary controller 11 controls the first ventilating fan 4 to be started, so as to suck and discharge the indoor air to the outdoor.

[0054] It may cause discomfort to the human body when the indoor humidity is relatively higher. Therefore, in this embodiment, the humidity sensor 24 is disposed on the machine cover. The humidity sensor 24 detects the indoor humidity, and transmits a value of the indoor humidity to the primary controller 11. If the indoor humidity is higher than an indoor threshold, the primary controller 11 controls the first ventilating fan 4 to operate, so as to discharge the indoor air out of room. As a consequence, the indoor humidity is decreased.

[0055] It should be noted that ON / OFF of detection functions of the foregoing humidity sensor 24, temperature sensor 23, and infrared sensor may all be self-set by the user. Moreover, the humidity sensor 24, the temperature sensor 23, and the infrared sensor may be in a communication connection to the primary controller 11 in a wired or wireless manner.

[0056] As an optional implementation, as shown in FIG. 7, it may further include a second exhaust component 12 and a second driving member 13. The second exhaust component 12 is disposed within a region enclosed by the restriction component 8.

[0057] In this embodiment, the second exhaust component 12 may be disposed above or below the first exhaust component 9. A structure of the second exhaust component 12 is same to that of the first exhaust component 9. The first exhaust component may rotate towards two 26 01 21 directions, and a rotation direction of the second exhaust component is perpendicular to a rotation direction of a first exhaust plate. For example, the exhaust plate of the first exhaust component 9 rotates from the east to the west or from the west to the east, and an exhaust plate of the second exhaust component 12 rotates from the south to the north or from the north to the south.

[0058] In this case, the hot air is guided to four directions through a combination of the first exhaust component 9 and the second exhaust component 12, thus further improving the effect of preventing the hot air from being directly blown to the human body.

[0059] The side wall of the heat dissipation hole 22 is further provided thereon with a third infrared sensor 223 and a fourth infrared sensor 224, and a connection line between the third infrared sensor 223 and the fourth infrared sensor 224 is perpendicular to a connection line between the first infrared sensor 221 and the second infrared sensor 222. Detection directions of the third infrared sensor 223 and the fourth infrared sensor 224 are opposite to each other.

[0060] Specifically, it may be determined, whether there is a person in an opposite direction inside the room, by using the third infrared sensor 223 and the fourth infrared sensor 224. Subsequently, detection in multiple directions may be realized through cooperation of the first infrared sensor 221 and the second infrared sensor 222, so as to determine the position of the human body more accurately.

[0061] As an optional implementation, the first motor 102 includes a stepper motor.

[0062] As an optional implementation, the second motor 112 includes a stepper motor.

[0063] The stepper motor is an open-loop control element stepper motor that converts an electrical impulse signal into an angular displacement or a linear displacement. The stepper motor may achieve the goal of accurate positioning by controlling a magnitude of the angular displacement by means of controlling the number of pulses.

[0064] It can be seen from the foregoing technical solutions that the embodiments of this application provide a smart air-heating bathroom heater. The air-heating bathroom heater includes: the main case, the restriction component, the machine cover, the first exhaust component, the first driving member, and the primary controller. When a function of the air-heating bathroom heater for increasing the indoor temperature is enabled, after receiving signals of the determined position of the human body that are sent by the first infrared sensor and the second infrared sensor, the primary controller controls the first driving member based on the position of the human body. The first driving member alters the rotation angle of the first exhaust component, to prevent the hot air outputted from the heat dissipation hole from being directly blown to the human body, thereby improving user experience of the smart air-heating bathroom heater. 26 01 21 26 01 21
