Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and more specifically, to a fan with a diffuser. Background Technology

[0002] The existing indoor air conditioning heating has a drawback: the air outlet is high, and hot air rises more easily, causing the heat to be concentrated in the upper part of the room. This results in temperature stratification between the upper and lower parts of the room, making the user's face drier, while the lower part of the room, which is not heated, is difficult to warm up, and the user's feet usually feel cold.

[0003] While existing bladeless fans can also provide heating, their airflow is relatively linear, resulting in a large amount of hot air being blown directly at the user, causing discomfort and a poor user experience.

[0004] Although baseboard heaters can heat the room along the bottom without directly emitting heat to the user, and can effectively heat the lower areas of the room while avoiding heat concentration in the higher areas, providing the best heating experience, baseboard heaters themselves have no other functions and are limited to a single use case.

[0005] Therefore, this invention provides a fan with a diffuser. Utility Model Content

Figure 2 This is a side view of the first type of fan with a diffuser according to the present invention. Figure 3 This is a front view schematic diagram of the first type of fan with a diffuser according to this utility model. Figure 4 This is a cross-sectional schematic diagram of the first diffuser in the first type of fan with a diffuser according to the present invention. Figure 5 This is a cross-sectional schematic diagram of the nozzle component and the fan section in the first type of fan with a diffuser according to this utility model. Figure 6This is a perspective view of the first type of fan-equipped heater with a diffuser according to this utility model. Figures 1 to 6 As shown, the fan with diffusers of this invention includes: a lifting base, a fan section 2, and a nozzle section. The lifting base includes a base and a lifting rod 1. The fan section 2 is connected to the upper end of the lifting rod 1, and has a built-in fan 21 that generates airflow. The nozzle section includes a three-way air distribution seat 3 and two diffusers. The main pipe of the three-way air distribution seat 3 is rotatably connected to the fan section 2, and the diffusers are rotatably connected to two branch pipes of the three-way air distribution seat 3 along a first rotation axis. The diffusers are equipped with heating units and air outlets. In heating mode, the airflow passes through the heating unit and is emitted vertically upwards from the air outlets. Therefore, the first type of vertical fan with diffusers of this invention can be used as a regular fan when the fan is working and generating airflow (at which time the heating unit is not working), and the two diffusers can independently adjust the airflow angle to blow air in different directions. Furthermore, after the fan section 2 is lowered, the air outlet direction of the two diffusers can be vertically upward. The fan and heating unit work together to blow hot air vertically upward from the bottom surface, thereby achieving a user experience similar to that of a baseboard heater. This expands the user experience of the bladeless fan and optimizes the user experience of using a bladeless fan for heating.

[0057] In a preferred embodiment, in heating mode, after the lifting rod 1 is shortened, the fan unit 2 is brought close to the ground. At this time, the air inlet of the fan unit 2 remains suspended (to avoid sucking in ground dust), and the distance between the fan unit 2 and the ground can be less than 20cm, as close to the ground as possible. The diffuser is rotated to emit a stream of hot air vertically upward from the air outlet, but this is not a limitation. In some variations, in heating mode, the distance between the fan unit 2 and the ground can be one of 3cm to 60cm, for example: 3cm, 5cm, 10cm, 15cm, 30cm, 40cm, 50cm. The smaller the distance between the fan unit 2 and the ground, the more conducive it is to heating the temperature near the ground, achieving a certain foot-warming effect, which will not be elaborated further here.

[0058] In a preferred embodiment, the fan unit 2 further includes an air inlet 22 and an air outlet 23 located at both ends of the fan 21. The air outlet 23 is located at the first end of the fan unit 2 and is connected to the main pipe of the three-way air distribution seat 3. An air intake grid 24 is provided at the bottom of the second end of the fan unit 2. External air reaches the air inlet 22 of the fan unit 2 through the air intake grid 24, but is not limited thereto.

[0059] In a preferred embodiment, the shaft of the fan 21 is perpendicular to the lifting rod 1, but this is not a limitation.

[0060] In a preferred embodiment, a first diffuser 4 and a second diffuser 5 are included, the first diffuser 4 and the second diffuser 5 being symmetrically based on the three-way air distribution seat 3, but not limited thereto.

[0061] In a preferred embodiment, the three-way air distribution seat 3 is provided with an air distribution wall 31 inside. The air distribution wall 31 includes an air distribution tip and guide slopes located on both sides. Air flows through the guide slopes of the air distribution tip and is guided to the first diffuser 4 and the second diffuser 5 respectively, but is not limited thereto.

[0062] In a preferred embodiment, the housing of the first diffuser 4 is provided with a first slit nozzle 41, the extension direction of the first slit nozzle 41 being parallel to the first rotation axis. The housing of the second diffuser 5 is provided with a second slit nozzle 51, the extension direction of the second slit nozzle 51 being parallel to the first rotation axis, but not limited thereto.

[0063] In a preferred embodiment, a first heating element 42 is provided on both sides of the first slit nozzle 41, and a second heating element is provided on both sides of the second slit nozzle 51, but this is not a limitation.

[0064] In a preferred embodiment, an air purifier is provided between the air intake grid 24 and the air inlet 22 of the fan section 2. The entire fan unit can also be used as an air purifier, but is not limited thereto.

[0065] In a preferred embodiment, the fan unit 2 is rotatably connected to the upper end of the lifting rod 1, but this is not a limitation.

[0066] The specific embodiments of this utility model are as follows:

[0067] refer to Figure 1 , 2 As shown in Figures 3, 4, and 5, when the first type of fan with a diffuser of this utility model is used as a regular standing fan, the heating unit (first heating element 42 and second heating element) is not working, and the fan 21 works to generate an airflow. After the airflow enters the three-way air distribution seat 3, it is guided by the guiding slope of the air distribution wall 31 to the first diffuser 4 and the second diffuser 5 respectively. Then, it is emitted outward from the first slit nozzle 41 of the first diffuser 4 and the second slit nozzle 51 of the second diffuser 5, so as to realize the function of a regular fan. It also has the advantage of emitting airflow in two different directions at the same time, which is beneficial for use as an indoor air circulation fan.

[0068] refer to Figure 6As shown, when the first type of fan with diffusers of this utility model is used as a footrest heater, the height of the lifting rod 1 can be shortened to lower the fan unit 2 to a height close to the ground. Then, the air outlet direction of the two diffusers is vertically upward (at this time, the nozzles are placed along the horizontal axis, and the air outlet direction of the first slit nozzle 41 and the second diffuser 5 is vertically upward). The fan 21 and the heating unit (first heating element 42 and second heating element) work together. The fan 21 generates an airflow, which enters the three-way air distribution seat 3 and is guided by the guide slope of the air distribution wall 31 to the first diffuser 4 and the second diffuser 5 respectively. The airflow is then further guided by the first heating element 42 and the second heating element. After the two heating elements heat up, the heated airflow is emitted vertically upward from the first slit nozzle 41 of the first diffuser 4 and the second slit nozzle 51 of the second diffuser 5. At this time, the fan of this invention can heat along the bottom of the room without directly emitting heat to the user, and can effectively heat the low area of ​​the room, avoiding the high area where heat is concentrated, resulting in the best heating experience. It fully realizes the user experience similar to the baseboard heater, thereby expanding the user experience of the bladeless fan, optimizing the user experience of using the bladeless fan for heating, and allowing the fan of this invention to play different roles in all four seasons (it can achieve multiple effects such as blowing and cooling, air purification, and low-level whole-room heating).

[0069] Figure 7 This is a perspective view of a table fan with a diffuser, representing the second type of fan according to this utility model. Figure 8 This is a perspective view of the second type of fan-equipped heater with a diffuser according to this utility model. Figure 7 and 8 As shown, the difference between the second type of fan with a diffuser and the first type of fan with a diffuser is that the fan does not use a lifting base, but instead uses a desktop tripod 6 to support the fan unit 2 (the other technical features are the same as the first type of fan with a diffuser). The unfolded height of the desktop tripod 6 is less than 20cm, so as to form a table fan (mainly used at desktop height). In heating mode, the second type of fan with diffusers is placed directly on the ground, with the air outlet direction of the two diffusers vertically upward. The fan 21 and the heating unit (first heating element 42 and second heating element) work together. The fan 21 generates airflow, which enters the three-way air distribution seat 3 and is guided by the guide slope of the air distribution wall 31 to the first diffuser 4 and the second diffuser 5 respectively. After passing the first heating element 42 and the second heating element, the airflow is heated by the two heating elements. The heated airflow is then emitted vertically upward from the first slit nozzle 41 of the first diffuser 4 and the second slit nozzle 51 of the second diffuser 5, thus achieving a user experience similar to that of a footrest heater, thereby expanding the user experience of the bladeless fan and optimizing the user experience of using a bladeless fan for heating.

[0070] In summary, the purpose of this utility model is to provide a fan with a diffuser that can switch between two modes: a bladeless fan and a footrest heater, thereby expanding the application scenarios of bladeless fans and optimizing the user experience.

[0071] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications or substitutions should be considered within the protection scope of the present invention.
