The height of the first support portion 51 can be set at a reasonable height, so that the overall height of the heater is about a height convenient for human touch, such as between 70cm-90cm, which is more ergonomic and convenient for use and handling. Improve user experience. Further optionally, the width of the heater is 40cm-60cm, so that the width of the heater is moderate, and the heat distribution is suitable, which is convenient for users to use and take, and saves space for the heater.

In this embodiment, the number of the first support portions 51 is two. The two first support portions 51 are located on opposite sides of the casing 10, and two ends of the second support portion 52 are respectively connected to the two first support portions 51. The one support portion 51 and the second support portion 52 may be an integrally formed structure, which is convenient for strengthening the structural strength at the connection between the first support portion 51 and the second support portion 52. Further, the first support portion 51 is formed as a hollow columnar structure inside, and the inside of the first support portion 51 communicates with the accommodation cavity 10a; an inner side of the first support portion 51 facing the other first support portion 51 is formed along the height direction The multiple air outlet holes 51a are arranged, and the hot airflow in the accommodating cavity 10a enters the inside of the first support portion 51, and is then sent out through the multiple air outlet holes 51a. In this way, the clothes hanging on the second support portion 52 can be dried faster. At the same time, the clothes are heated more evenly.

Referring to FIGS. 1 and 2, the control panel 60 may be disposed on the upper surface of the second support portion 52, which is convenient for users to control and can operate normally without bending over. Specifically, the control panel 60 is exposed on the upper surface of the second support portion 52. The control device is disposed in the accommodating cavity 10a. The control panel 60 is connected to the control device through a control line (not shown). Inside a support portion 51, the structure of the heater can be fully utilized in this way, making the structure more compact. The control device is electrically connected to the fan component 20, the driving component, and the heating component 30. The control panel 60 sends a control instruction to the control device. The control device can control the working states of the fan component 20, the driving component, and the heating component 30 according to the control instruction.

The heater includes a first working mode, a second working mode, a third working mode, a fourth working mode, and an intelligent preheating mode. The control panel 60 is formed with a first mode key (not shown) for triggering the first working mode, a second mode key (not shown) for triggering the second working mode, and a third working mode for triggering The third mode key (not shown in the figure) and the fourth mode key (not shown in the figure) for triggering the fourth working mode, it can be understood that the above-mentioned mode key can be a physical key or a touch Key; the first mode key, the second mode key, the third mode key, and the fourth mode key can be independently set on the control panel 60, or can be integrated into a mode switch key, which can be triggered in cycles In order to make the heater switch between the first working mode, the second working mode, the third working mode and the fourth working mode, the order of the multiple working modes is not limited, as long as it can be selected sequentially . When the heater is in the first working mode, the control device controls the second driving member 42 to drive the wind wheel housing 22 to rotate, so that the airflow outlet 22a is aligned with the second air outlet 11a, and the first driving member 41 is driven to drive the wind wheel 21 so that The speed rotates, and the heater is in the first working mode. When the second mode key is triggered, the control device controls the second driving member 42 to drive the wind wheel housing 22 to rotate, so that the air outlet 22a is aligned with the first air outlet 13a, and controls the first driving member 41 to drive the wind wheel 21 at a second speed. Turn, the heater is in the second working mode. The second rotation speed may be the same as or different from the first rotation speed. When the third mode key is triggered, the control device controls the airflow outlet 22a toward the second air outlet 11a, the wind wheel 21 rotates at a third speed, and the heater is in a third working mode, wherein the third speed is less than the first speed. When the fourth mode key is triggered, the wind wheel 21 stops rotating. At this time, the hot air flow inside the receiving cavity 10a naturally convects, which is suitable for the bathing process.

Before bathing, the user can trigger the first mode key, and the wind wheel 21 sends the hot air flow from the second air outlet 11a at a large first speed to quickly heat the air in the bathroom; it can also trigger the smart preheat key, the wind wheel 21 The hot airflow is sent from the second air outlet 11a at a larger first rotation speed for a preset time and stops rotating, that is, the heater quickly heats the air in the bathroom and then slowly heats by natural convection. When laundry is hung on the second support portion 52, if the laundry needs to be dried or heated, the second mode key can be triggered, and the wind wheel 21 sends the hot airflow from the first air outlet 13a at a larger second rotation speed. The hot air stream blows directly onto the clothes, drying them quickly. And the clothes are far away from the casing 10, the clothes will not be locally overheated, and the clothes will not be damaged. When the bath is over, a third mode key can be triggered, the wind wheel 21 rotates at a smaller third rotation speed, and the hot air blows from the second air outlet 11a to the user's feet, quickly drying the water vapor on the user's feet. When there is no need for air blowing, the fourth mode button can be triggered, and the hot air flow will naturally convect.
