Abstract

The utility model discloses a push suction type tower range hood convenient for disassembly of an impeller, comprising a shell, and a smoke collecting cover, a ventilation ring and a screen which are connected on the lower side of the shell, wherein, a spiral case is arranged inside the shell, and the impeller is arranged inside the spiral case. The utility model is characterized in that: an air intake of the spiral case opens downward and an air outlet of the spiral case opens upward; an air inlet concentric with the air intake of the spiral case and the impeller is arranged on the smoke collecting cover; the outer diameter of the impeller is smaller than the diameter of the air intake of the spiral case and the air inlet on the smoke collecting cover; the ventilation ring and the screen are arranged on the air inlet of the smoke collecting cover; the connection between the ventilation ring and the screen and the smoke collecting cover is dismountable. The utility model adopts a push suction type blower system; when the blower impeller and so on of the range hood are needed to be disassembled, the blower impeller and so on can be conveniently taken out from the lower side of a blower shell, and all the work can be quickly completed by manual operation, thereby the operations of disassembly and cleaning are made to be very simple and convenient.

Description

The top suction type tower range hood of impeller for convenience detach
Technical field
The utility model relates to a kind of top suction type tower range hood of tower range hood, particularly a kind of impeller for convenience detach.
Background technology
The tower range hood is called European range hood usually again.The general side-suction type blower fan system of existing tower range hood.Its structure is general shown in Chinese patent CN02252991.8 disclosed " a kind of detachable tower range hood ", comprise casing, exhaust fume collecting hood and face shield, casing is made of a back plate, biside plate and a top board, one centrifugal fan that is made of motor-driven receded disk impeller and spiral case is housed in the casing, one air outlet is arranged on the top board, exhaust fume collecting hood is fixed on the lower end of casing, mask mounting shell biside plate front end.There is the deficiency (referring to Fig. 1) of following two aspects in the European range hood of this structure: 1, the user is when cleaning the range hood impeller, the dismounting impeller is cumbersome, as shown in Figure 1, must open fan cover 1 ' (being face shield) earlier, and then with screwdriver take out air inlet 2 ', take out successively hand-tight nut 3 ' and impeller 4 '.And before opening fan cover, generally also to take away blower hood and cover of upholstery, very time-consuming, assembling is trouble.2, the easy laying dust of casing and fan cover junction, if seal bad also possibility oil impregnate, there is seam inevitably in the two junction, lacks associative perception, influences product appearance and quality.
Summary of the invention
Technical problem to be solved in the utility model is the top suction type tower range hood of a kind of impeller for convenience detach of exploitation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the top suction type tower range hood of this impeller for convenience detach, comprise casing, be connected the exhaust fume collecting hood of inferior surface of machine case, air-ducting ring and guard, spiral case is housed in the casing, impeller is housed in the spiral case, the air intake vent that it is characterized in that described spiral case down and air outlet up, have air intake vent and the concentric air inlet of impeller on the exhaust fume collecting hood with spiral case, and the external diameter of impeller is less than the diameter of air inlet on spiral case air intake vent and the exhaust fume collecting hood, described air-ducting ring and guard are installed in the air inlet place of exhaust fume collecting hood, and air-ducting ring, being connected between guard and the exhaust fume collecting hood removably connects.
Described air-ducting ring and described guard are structure as a whole.
Syndeton between described air-ducting ring, guard and the described exhaust fume collecting hood is the combined connecting structure between screw syndeton, magnetic structure, buckle syndeton or this three.Screw syndeton, magnetic structure, buckle syndeton are the existing known structure that removably connects, and have a detailed description in the existing patent of applicant.
The number of tie point is 2~4 between described air-ducting ring, guard and the described exhaust fume collecting hood.
Compared with prior art, advantage of the present utility model is: what 1, use is the top suction type fan system, and has broken through traditional impeller demolition mode.Its method is directly to get impeller from the exhaust fume collecting hood below, brings great convenience to client.2, need pull down that impeller cleans, during maintenance, need not to pull down fan cover, only need pull down air-ducting ring and guard from exhaust fume collecting hood, take off the hand-tight nut of impeller then, impeller is taken out from spiral case get final product, thereby operation is very easy, installation makes things convenient for too; 3, air inlet adopts under magnetic structure and the situation that spiral case is connected, tool free during dismounting, and on the spiral case so and corresponding constructions such as nut seat or snap seats need be set.Air inlet adopts under buckle and the situation that spiral case is connected, can adopt hand-tight screw, thereby also need not can pull down with instrument the screw of lower edge, thereby dismounting is very simple.4, because impeller can be easily taken out from the Fan casing below, thereby need not connecting a fan cover under detachable on the Fan casing, that is to say can be one-body molded on Fan casing with fan cover, so the outward appearance of product and quality will significantly improve.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 2~illustrated in Figure 5, be a preferred embodiment of the present utility model.As Fig. 2~shown in Figure 5, the top suction type tower range hood of present embodiment impeller for convenience detach, comprise casing 1, be connected exhaust fume collecting hood 2, air-ducting ring 3 and guard 4 below the casing 1, spiral case 5 is housed in the casing 1, by hand-tight nut 6 impeller 7 is installed in the spiral case 5, the air intake vent 51 of spiral case 5 down and air outlet 52 up, have the air inlet 21 concentric on the exhaust fume collecting hood 2, and the external diameter of impeller 7 is less than the diameter of air inlet 21 on spiral case air intake vent 51 and the exhaust fume collecting hood 2 with the air intake vent 51 of spiral case 5 and impeller 7.Described air-ducting ring 3 and guard 4 are structure as a whole, air inlet 21 places that its screw syndeton by guard 4 edges and two magnetic structures are removably mounted on exhaust fume collecting hood 2.The screw syndeton comprises screw 8, and this screw 8 passes the through hole at guard edge and is screwed onto on the exhaust fume collecting hood 2.Magnetic structure comprises the magnet 9 that is arranged on guard 4 edges, and guard 4 promptly is attached on the exhaust fume collecting hood 2 because of the magnetic force of 9 pairs of exhaust fume collecting hoods 2 of magnet.
