Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a heater. Background Art

[0002] The existing heater includes a shell, a wind wheel, an air duct and a heating block arranged in the shell. In the air duct where the heating block is arranged, the airflow generated by the rotation of the wind wheel flows through the heating block and forms hot air to be transported outward to increase the indoor temperature. The existing air ducts are all single-channel settings, so that one end of the air duct is connected to the wind wheel, and the other end forms an air outlet connected to the indoor space. Due to the limited number and size of the air outlets, the air outlet efficiency and hot air flow rate are greatly affected, which not only affects the heating efficiency, but also affects the user experience due to uneven hot air diffusion. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the utility model provides a heater with an annular air duct. An annular air duct is arranged inside the shell and connected to the outside through multiple air outlets, which can effectively increase the hot air output flow rate and the heating efficiency, and also effectively increase the hot air output flow rate, increase the hot air diffusion range, and improve the user experience.

[0004] The utility model is realized in the following manner: a heater with an annular air duct, comprising a shell, a wind wheel and an air duct with a heating block are arranged in the shell, the air duct is annular, the wind wheel is arranged in the middle of the air duct, and a plurality of equally spaced air outlets are arranged on the outer edge of the air duct, and the airflow generated by the rotation of the wind wheel flows radially through the air duct and diffuses outward through the air outlets. An annular air duct is arranged in the shell and is connected to the outside through a plurality of air outlets, which not only effectively increases the hot air output flow rate and the heating efficiency, but also effectively increases the hot air output flow rate, ensures that the airflow can flow circumferentially in the air duct, effectively reduces kinetic energy loss, and thus increases the hot air diffusion range and improves the user experience.

[0005] Preferably, the inner edge of the air duct is arranged adjacent to the periphery of the wind wheel, so that the air duct receives the airflow from the wind wheel through the inner edge. The inner edge of the air duct is exposed toward the wind wheel, and the airflow generated by the rotation of the wind wheel can flow radially into the air duct and be transported to each air outlet, so that each air outlet obtains a uniform airflow.

[0006] Preferably, the air outlet is strip-shaped and arranged along the outer edge of the air duct, and the corresponding ends of adjacent air outlets are arranged adjacent to each other to increase the coverage area of ​​the air outlet on the outer edge of the air duct and reduce the wind resistance of the airflow discharged from the air duct. The air outlet is arranged along the outer edge of the air duct, which facilitates the outward flow of the airflow by increasing the coverage area of ​​the air outlet, thereby reducing the resistance of the airflow when it is discharged, effectively maintaining the airflow velocity, thereby expanding the airflow diffusion range, and ensuring that the airflow can be evenly diffused to the surroundings.

[0007] Preferably, the inner edge port of the air duct is horizontally arranged toward the wind wheel, and the inner edge port is aligned at the same height as the outer edge of the wind wheel, ensuring that the airflow output from the wind wheel can all flow into the air duct and be discharged through the air outlet, effectively reducing the kinetic energy loss of the airflow during the transportation process.

[0008] Preferably, the outer edge of the air duct is provided with a turning fillet so that the air outlet is exposed downward. The airflow in the air duct completes the turning operation when flowing through the turning fillet, so that the airflow can be transported outward through the air outlet exposed downward, and the kinetic energy loss of the airflow when turning is effectively reduced.

[0009] Preferably, the heating block is arranged in the air outlet, and the air flow in the air duct passes through the heating block to form hot air that is discharged externally, which not only ensures that the heating block can heat the air flow passing through the air outlet, but also ensures that the air flow is discharged in time after being heated and heated, preventing hot air from flowing in the air duct, effectively reducing the shell temperature and extending the service life.

[0010] Preferably, the heating block is independently controlled, and the temperature of the airflow is adjusted by adjusting the start and stop state and the operating power of the heating block, and then adjusted according to usage conditions, thereby effectively improving the user experience.

[0011] Preferably, the air outlet is provided with a swinging flap that can be opened and closed, and the swinging flap can be swung and switched between a closed state for blocking the air outlet and a guiding state for guiding the hot air to turn. The swinging flap can block the air outlet when switched to the closed state, so that the airflow in the air duct is discharged through other air outlets. Since the airflow delivery direction and area are controlled, the airflow direction can be adjusted by swinging after switching to the guiding state, so as to facilitate the adjustment of the airflow diffusion range and area.

[0012] Preferably, the housing is square, and the air outlet is rectangular and arranged on four edges of the bottom surface of the housing. The square housing is convenient for use with an integrated ceiling, and is also convenient for setting a rectangular air outlet, which effectively simplifies the structure and facilitates production, assembly and control.

[0013] Preferably, an air inlet is provided in the middle of the bottom surface of the housing, and the middle of the wind wheel draws air through the air inlet to form a radial airflow input into the air duct. The air inlet is connected to the indoor space, so that the wind wheel can draw outside air through the air inlet and provide airflow for the air duct, thereby adjusting the indoor temperature by driving the airflow to circulate.

[0014] The beneficial effects of the utility model are as follows: a ring-shaped air duct is arranged in the shell and connected with the outside through multiple air outlets, which not only effectively increases the hot air output flow rate and the heating efficiency, but also effectively increases the hot air output flow rate, ensures that the airflow can flow circumferentially in the air duct, effectively reduces kinetic energy loss, and thus increases the hot air diffusion range and improves the user experience.

[0019] The essential features of the present utility model are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1 and 2 The heater with an annular air duct shown is composed of a shell 1 and an air duct 4 with a fan wheel 2 and a heating block 3 arranged in the shell 1. The air duct 4 is annular, and the fan wheel 2 is arranged in the middle of the air duct 4. The outer edge of the air duct 4 is provided with a plurality of equally spaced air outlets 5. The airflow generated by the rotation of the fan wheel 2 flows radially through the air duct 4 and diffuses outward through the air outlets 5. The annular air duct 4 is arranged in the shell 1 and is connected to the outside through a plurality of air outlets 5, which not only effectively improves the hot air output flow rate and the heating efficiency, but also effectively improves the hot air output flow rate, ensures that the airflow can flow circumferentially in the air duct 4, effectively reduces kinetic energy loss, and thus increases the hot air diffusion range and improves the user experience.

[0021] In actual operation, the shell 1 includes an upper shell and a lower shell that are independently processed and can be stacked and assembled. The upper shell and the lower shell are vertically stacked and assembled to form the shell 1. The middle part of the shell 1 forms a space for installing the wind wheel 2, and the periphery of the shell 1 forms an annular air duct 4. The annular air duct 4 includes an air inlet port provided at its inner edge and an air outlet port provided at its outer edge, and the air outlet is formed at the air outlet port. When in use, the wind wheel 2 rotates and forms an airflow that diffuses radially outward. The airflow flows into the air duct 4 through the air inlet port and flows to the air outlet port in the air duct 4 in an expanding spiral shape, and then is discharged outward through the air outlet. Since there is no obstruction in the air duct 4, the airflow can flow along a spiral path in the air duct 4, ensuring that the airflow maintains a high kinetic energy and maintains a flow rate, thereby ensuring that the airflow is effectively transported.

[0022] In actual operation, the inner edge of the air duct 4 is arranged adjacent to the periphery of the wind wheel 2, so that the air duct 4 receives the airflow from the wind wheel 2 through the inner edge. The inner edge of the air duct 4 matches the contour of the periphery of the wind wheel 2, so that the air inlet port of the air duct 4 can effectively receive the airflow output by the wind wheel 2, thereby maintaining the flow rate by reducing wind resistance.

[0023] In actual operation, the air outlet 5 is strip-shaped and arranged along the outer edge of the air duct 4, and the corresponding ends of adjacent air outlets 5 are arranged adjacent to each other to increase the coverage area of ​​the air outlet 5 on the outer edge of the air duct 4 and reduce the wind resistance of the airflow discharged from the air duct 4. Specifically, the shell 1 is square, and the air outlet 5 is rectangular and arranged on the four edges of the bottom surface of the shell 1, which is convenient for the shell 1 to be used in conjunction with the integrated ceiling, and also convenient for setting a swingable and controllable swing leaf 8 at the rectangular air outlet 5, thereby controlling the operating state of the air outlet 5, and increasing the area of ​​the air outlet 5 by increasing the length of the air outlet 5, thereby ensuring that the airflow flowing along the spiral path in the air duct 4 can be discharged smoothly, reducing kinetic energy loss, and expanding the airflow coverage range.

[0024] In actual operation, the inner edge port of the air duct 4 is horizontally arranged toward the wind wheel 2, and the outer edge of the air duct 4 is provided with a turning radius 6 to expose the air outlet 5 downward, which is convenient for the vertical placement of the axis of the wind wheel 2 and ensures that the air inlet port of the air duct 4 can effectively receive the airflow from the wind wheel 2, and can also guide the airflow through the air duct 4 to be transported to the indoor space below. By setting the turning radius 6, the kinetic energy loss of the airflow is reduced, ensuring that the airflow is diffused to a larger range at a higher flow rate.

[0025] In actual operation, the heating block 3 is arranged in the air outlet 5 (such as Figure 3 As shown in the figure, the airflow in the air duct 4 flows through the heating block 3 to form hot air for external discharge. The heating block 3 heats the airflow out of the air duct 4, which can not only improve the heat transfer efficiency and prevent heat loss during the flow of the airflow, but also reduce the temperature of the housing 1, prevent the electrical components in the housing 1 from malfunctioning due to excessive temperature, and extend the life of the heater.

[0026] In actual operation, the heating block 3 is independently controlled, and the air outlet 5 is provided with a swinging leaf 8 that can be opened and closed and swung. The swinging leaf 8 can be swung and switched between a closed state that blocks the air outlet 5 and a guiding state that guides the hot air to turn. The controllability of the heater is improved by independently controlling the heating block 3 and the corresponding swinging leaf 8. The hot air temperature can be adjusted by opening and closing the heating block 3 to switch between normal temperature and high temperature. The corresponding air outlet 5 can be blocked by switching the swinging leaf 8 to a closed state, effectively increasing the airflow rate of other air outlets 5 so that the airflow can be concentrated in a preset direction. The airflow direction can also be adjusted by switching the swinging leaf 8 to a guiding state so that the airflow energy is concentrated in a preset area.

[0027] In actual operation, an air inlet 7 is provided in the middle of the bottom surface of the housing 1, and air is extracted from the middle of the wind wheel 2 through the air inlet 7 to form a radial airflow input into the air duct 4. The air inlet 7 and the wind wheel 2 are coaxially arranged, and the diameter of the air inlet 7 is close to the radius of the wind wheel 2. The air flow rate is increased by increasing the size of the air inlet 7, and the size of the air inlet 7 is limited to ensure that the peripheral portion of the wind wheel 2 can be effectively wrapped by the housing 1, thereby effectively improving the operating efficiency of the wind wheel 2.
