Description

Technical Field

[0001] The utility model belongs to the technical field of air heaters, in particular to a tower-type air heater. Background Art

[0002] A heater is an electrical appliance used to increase the ambient temperature. Its basic form is that the internal fan component works and forces the indoor air to flow into the heater from the air inlet. The air flow is heated by the heating component inside the body and then blown out from the air outlet to achieve a heating effect.

[0003] However, most existing air heaters have only one air outlet, and the air outlet is usually designed to be arranged at a high position, which results in the user's feet not being effectively covered by the heat field, resulting in insufficient heating of the user's feet; and some air heaters with upper and lower double air outlets, in order to avoid mutual interference of internal structures, usually use L-shaped or bent air ducts to make the air flow horizontally from the lower position or make the air outlet direction downward, but this type of air duct turning will lead to reduced air outlet efficiency and deterioration of thermal efficiency, resulting in attenuation of the heat field in the user's foot area and a poor user experience. Summary of the Invention

[0004] In order to solve the deficiencies in the prior art, a tower heater is provided which can heat the feet of a user.

[0005] The utility model is implemented by the following technical solutions:

[0006] The fan is housed in a foldable container, the container being arranged so that the fan is moved in a direction of rotation and the like, and the fan is moved in a direction of rotation relative to the fan.

[0007] The upper airflow chamber is directly opposite to the area above the user's feet, and the lower airflow chamber is directly opposite to the area above the user's feet.

[0008] The second power module and the third power module may have the same structure or different structures.

[0009] By vertically separating the upper airflow chamber and the lower airflow chamber in the body, horizontal air outlet is guaranteed while reducing the air outlet height of the lower airflow chamber. Compared with the existing air duct design, it can avoid turbulence interference and thermal efficiency degradation in the air outlet area, allowing users to use this heater to provide centralized heating for the feet, and open and close the second power module and the third power module separately as needed to achieve separate control of the upper airflow chamber and the lower airflow chamber, which is suitable for the user's flexible usage needs.

[0010] Preferably, the second power module is a DC fan, and the DC fan is located in a radial position close to the lower air outlet area, thereby achieving air flow in the lower airflow cavity.

[0011] Preferably, the DC fan includes an air duct housing formed by a square enclosed structure.

[0012] By setting up the air duct shell, the air can be blown out in a cross-sectional shape equivalent to the air duct shell, so that the air located at the lower side of the lower air outlet area can be blown out parallel to the ground, reducing the degradation of thermal efficiency caused by heating of the ground.

[0013] Preferably, the third power module is a cross-flow fan.

[0014] Since the area above the user's feet usually has exposed skin, strong wind blowing directly on the exposed skin will cause the user to feel uncomfortable. The cross-flow fan set up can achieve large-area smooth air discharge from the upper air flow cavity, thereby ensuring the user's usage experience.

[0015] Among them, when the DC fan is started alone, the body only supplies air through the lower airflow cavity on the lower side, thereby concentrating on heating the user's feet; when the cross-flow fan is started alone, the body only supplies air through the upper airflow cavity on the upper side, thereby concentrating on heating the area above the user's feet; when the DC fan and the cross-flow fan are started at the same time, the body supplies air through the upper and lower airflow cavities at the same time, thereby heating the user's entire body.

[0016] Preferably, the power source of the cross-flow fan is located at the lower end of the axis.

[0017] Since the upper airflow cavity is located above the machine body and is affected by the axial length of the cross-flow fan, the power source of the cross-flow fan is located at the lower end of the axis. Compared with the method of setting the power source of the cross-flow fan at the upper end of the axis, it can avoid the problem of the machine body's center of gravity being too high due to the power source, thereby causing the machine body to easily tip over.

[0018] Preferably, when the first power module is started, the first power module drives the body to rotate through the reaction force between the first power module and the base.

[0019] By driving the body to rotate by the first power module to adjust the upper airflow cavity and the lower airflow cavity, the heat spreading range can be increased. Compared with the design of the swinging guide vane, the turbulence generated in the air outlet area can be reduced, and the reduction in air outlet efficiency and degradation of thermal efficiency caused by the forced change of wind direction by the guide vane can be avoided.

[0020] Preferably, the first power module is a crank swing mechanism, the body and the base are rotationally connected, and a linear slide groove is provided in the base for the power output end of the crank swing mechanism to be embedded.

[0021] Since the first power module that drives the body to swing is a crank swing mechanism, the crank swing mechanism can be located in a radially eccentric position within the body. Compared with the method of setting a swing motor at the axis center, a radial gap can be generated between the first power module and the third power module that are set at an eccentric position for the assembly of the second power module, so that the second power module can further make the air outlet close to the ground surface.

[0022] Preferably, the cross-sectional area of ​​the base is larger than the cross-sectional area of ​​the body, thereby ensuring the stability of the body during use.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] Horizontal radial straight air ducts are formed on the upper and lower sides of the machine body through the vertically separated upper and lower air flow cavities, and the cross-flow fan and DC fan are controlled separately, so that the whole machine can realize large-area soft air supply on the upper side and ground-type air supply on the lower side, so as to achieve thermal sniper heating that can heat the user's feet, the area above the feet, or the entire body, ensuring the user's experience.

The cross-sectional area of ​​the base 12 is larger than the cross-sectional area of ​​the body 11, and an upper airflow cavity 111 and a lower airflow cavity 112 are formed in the body 11, which are arranged along the axial direction and do not interfere with each other.

[0036] An upper heating unit (not shown in the figure) and a lower heating unit (not shown in the figure) are respectively provided in the upper airflow chamber 111 and the lower airflow chamber 112, so that the air outlet of the upper airflow chamber 111 and the air outlet of the lower airflow chamber 112 are hot air. The upper heating unit and the lower heating unit have the same structure as the existing technology.

[0037] like Figure 2As shown, the upper air flow chamber 111 includes an upper air inlet area, an upper flow area and an upper air outlet area arranged along the radial horizontal direction of the body 11, the upper air inlet area is an upper air inlet grille 31 located on the side of the body 11 facing away from the user, and the upper air outlet area is an upper air outlet grille 32 located on the side of the body 11 facing the user; the lower air flow chamber 112 includes a lower air inlet area, a lower flow area and a lower air outlet area arranged along the radial horizontal direction of the body 11, the lower air inlet area is the lower air inlet grille 21 located on the side of the body 11 facing away from the user, and the lower air outlet area is the lower air outlet grille 22 located on the side of the body 11 facing the user; the upper air inlet grille 31 and the upper air outlet grille 32, the lower air inlet grille 21 and the lower air outlet grille 22 respectively divide the upper air flow chamber 111 and the lower air flow chamber 112 into several sub-air flow chambers 113, thereby ensuring the flow uniformity of the airflow during the heating process and suppressing the formation of turbulence.

[0038] like Figure 2 As shown, a first power module 14 for changing the wind direction of the upper and lower air outlet areas is provided at the lower inner side of the body 11. When the first power module 14 is started, the first power module 14 drives the body 11 to rotate through the reaction force between the first power module 14 and the base 12.

[0039] like Figure 7 、 Figure 8 As shown, the first power module 14 is a crank swing mechanism, which includes a drive motor 15 arranged at an eccentric position at the lower end of the body 11. The power output shaft of the drive motor 15 is parallel to the axis of the body 11. A crank 16 is provided at the end of the power output shaft. A swing rod 17 is provided at the end of the crank 16 away from the power output shaft. The swing rod 17 is the power output end of the crank swing mechanism.

During this process, the angle formed between the extreme positions on both sides of the linear slide groove 19 and the rotation axis of the rotating connection structure 13 of the body 11 is the swing angle of the body 11 relative to the base 12.
