[0001] The utility model relates to the field of fresh air ventilation and heating electric appliances, especially relates to a hidden single-fan fan. BACKGROUND

[0002] In the field of fresh air ventilation and heating, whether it is a bathroom heater, a kitchen heater, a heater or a cooling and heating air conditioner, indoor air is heated and blown and dehumidified by centrifugal fan.

[0003] Because of the physical characteristics of the fan, the airflow of the centrifugal fan heater is generated by centrifugal throwing, so the air inlet direction is perpendicular to the air outlet direction. Therefore, the shape and size of the front air inlet area of the centrifugal heater are required to be high, and if the centrifugal fan heater is forcibly matched with the front panel, the air inlet of the fan will be overlapped with the linear air inlet, which will seriously lose the air volume, and will also suck air from other areas of the suspended ceiling layer, which will cause environmental pollution. During the heating process, the air above the suspended ceiling, which does not need to be heated, also participates in the heating cycle, causing waste of energy. Therefore, the utility model emerges as the times require. SUMMARY

[0004] In view of the above, the primary problem to be solved by the utility model is that the air inlet of the traditional fan is overlapped with the linear air inlet, which will seriously lose the air volume, and will also suck air from other areas of the suspended ceiling layer, causing pollution.

[0005] Therefore, the utility model provides a hidden single-fan fan, which is characterized by comprising a host computer and a host computer cover plate, the host computer comprises a machine case and a machine case cover plate, the host computer cover plate is arranged on the host computer and forms a sandwiched air inlet air duct with the machine case cover plate, a first air inlet communicating with the sandwiched air inlet air duct is formed in the host computer cover plate, and a second air inlet communicating with the sandwiched air inlet air duct is formed in the machine case cover plate; the fan of the host computer is located below the machine case cover plate and corresponds to the second air inlet; the host computer is also provided with a host computer air outlet and a host computer air outlet respectively communicating with the fan.

[0009] Preferably, a heating assembly is arranged at the air outlet of the main machine, and the control assembly controls at least the heating assembly and the fan.

[0010] Preferably, the fan is a forward-reverse centrifugal fan, the air inlet end of the air outlet cabin is connected to the forward air outlet end of the fan, and the air inlet end of the air exchange cabin is connected to the reverse air outlet end of the fan.

[0011] Preferably, a first air outlet is further arranged on the cover plate of the main machine, and the first air outlet is in position correspondence with the air outlet of the main machine.

[0012] Preferably, the first air outlet and the first air inlet are linearly arranged.

[0013] Preferably, a panel is further arranged on the cover plate of the main machine, the panel has a panel air inlet in position correspondence with the first air inlet and a panel air outlet in position correspondence with the first air outlet.

[0014] Preferably, the panel is implemented as a display panel with a lamp panel, or the panel is implemented as an integrated ceiling panel, a honeycomb panel, or a gypsum panel.

[0015] The above technical solutions can be implemented alone or in combination to achieve the following beneficial effects:

[0016] By means of the double-layer sandwich air duct design of the cover plate of the main machine and the cover plate of the machine case, the air inlet duct is designed inside the machine body, and the product has zero loss of air volume before and after installation; compared with the traditional direct-down type lighting lamp panel, the main machine does not need to be raised to increase the air inlet space of the fan, and full air volume output can be obtained without air volume loss; moreover, the air inlet duct of the whole main machine is designed in a hidden manner, the traditional panel can be omitted, and the main machine is directly used in cooperation with the opening of the ceiling panel, so that the whole design is presented as a linear and simple design on the ceiling panel.

[0021] The scheme ingeniously utilizes the middle region of the U-shaped air duct of the bidirectional impeller as the installation region of the electric control PCB module, fully utilizes the internal space of the machine body, and provides the possibility for the design of a large-size impeller.

[0022] The existing forward and reverse impeller is selected for the fan, the air duct in the machine case and the sandwich air inlet air duct need to be built-in in the machine body for adapting to the hidden design of the impeller, and the height of the impeller is also reduced. Meanwhile, the diameter of the impeller is increased, so that the performance attenuation caused by the non-complete air duct and the lower height is compensated. BRIEF DESCRIPTION OF DRAWINGS

The main unit cover 2 has a first air inlet 21 that connects to the sandwich air intake duct 10. The chassis cover 12 has a second air inlet 121 that connects to the sandwich air intake duct 10. The fan 13 of the main unit 1 is located below the chassis cover 12 and its position corresponds to the air intake through the second air inlet 121. The main unit 1 also has a main unit ventilation port 110 and a main unit air outlet 115 that are respectively connected to the fan 13. This embodiment uses a double-layer sandwich air duct design with the main unit cover 2 and the chassis cover 12 to design the air intake duct inside the body, resulting in zero airflow loss before and after installation. Compared with the traditional direct-down lighting panel 53, there is no need to raise the main unit 1 to increase the air intake space of the fan 13 to obtain full airflow output without any airflow loss. Moreover, the hidden air intake duct design of the entire main unit 1 eliminates the need for the traditional panel 5 and allows for direct use with the ceiling panel opening, presenting a simple linear design on the ceiling panel.
