A multi-protection structure for air intake of a wide temperature range air source heat pump unit

Abstract

The utility model relates to a wide temperature range air source heat pump unit air intake multiple protection structure, which solves the problem that the existing wide temperature range air source heat pump air intake system is easily blocked by external environmental impurities. It includes a wide temperature range air source heat pump unit panel, an air intake channel, an air filter and a protective mask. The air intake of the protective mask faces downward, so that the gas enters the protective mask from the bottom to prevent external dust and impurities from blocking the entrance of the air intake channel. As the first level of protection, the air outlet of the mask is connected to the air intake channel through the panel grille. The air intake end of the panel grille is higher than the air outlet end, so that the air is sucked upward under the action of gravity through the secondary turbulence, and rainwater and part of the particulate matter can be blocked outside the grille. As the second level of protection, the air intake channel allows the air flow in the channel to circulate, and part of the particulate dust is retained at the bottom of the channel, that is, as the third level of protection, the air filter again filters out a small amount of fine impurities in the air. As the fourth level of protection, it can improve the operating efficiency and service life of the wide temperature range air source heat pump.

[0016] The structure of the utility model is further described below in conjunction with the accompanying drawings.

[0017] Reference Figures 1 to 5A wide temperature range air source heat pump unit air intake multi-protection structure includes a wide temperature range air source heat pump unit panel 1, an air inlet 2 arranged on the panel, an air intake channel 3 connected to the air inlet, and an air filter 4. The multi-protection structure also includes a protective mask 5, the protective mask is fixed on the unit panel, the air inlet is the air inlet of the mask, the air inlet of the protective mask faces downward, and the air outlet of the mask is connected to the air intake channel through a panel grille 6. The panel grille is arranged to be laterally inclined, the air inlet end of the panel grille is higher than the air outlet end, and the air filter is located at the tail end of the air intake channel. Thereby, the gas enters the protective cover from the bottom, preventing external dust and impurities from blocking the entrance of the air intake channel. As the first level of protection, the air outlet of the mask is connected to the air intake channel through the panel grille. The panel grille is arranged to be laterally inclined, and the air intake end of the panel grille is higher than the air outlet end. Therefore, the air is sucked upward under the action of gravity through the secondary turbulence, and rainwater and some particulate matter can be blocked outside the grille. As the second level of protection, the air intake channel enables the air flow in the channel to circulate, and some particulate dust is directly retained at the bottom of the channel by gravity, that is, as the third level of protection, the air filter again filters out a small amount of fine impurities in the air. As the fourth level of protection, it can improve the operating efficiency and service life of the air source heat pump with a wide temperature range.

The grille plates are welded in the inclined grooves of the slotted side plates to form a common louver structure, which is characterized by simple structure, firm welding, no high mold costs caused by processing louvers, and flexible adjustment of the size and length of the louvers.

[0020] In this embodiment, strip-shaped air inlets 51 are provided on both side walls of the protective mask 5. Thus, air can be taken in from the bottom and sides of the protective mask at the same time, thereby improving the efficiency of air intake.
