Description

Rotary desk of microwave oven motor outer cover

The utility model relates to the turntable motor (turn table motor) of micro-wave oven, especially relates to the outer cover of the turntable motor of the conditioning dish rotation that drives micro-wave oven.

Fig. 1 is a micro-wave oven front structural map.In conditioning chamber 5, be provided with the conditioning dish 4 of rotation, usually should conditioning dish 4 be installed on conditioning dish fixedly on the tool 3 (hereinafter to be referred as fixing tool), with its rotation with three legs.Fixedly tool 3 drives and rotates by being located at matrix 2 following turntable motor 10.

But turntable motor 10 is installed on matrix 2 surfaces as mentioned above, and fixedly tool 3 top that is installed on matrix 2 is connected with conditioning dish 4, so tool 3 can pass matrix 2 and can rotate in order to make fixedly, is formed with on matrix 2 than the fixing big through hole 3a of tool 3 diameter pins.

On the other hand, in the conditioning chamber 5 of micro-wave oven 1, various foods to be nursed one's health, for example when conditioning has the food of soup,, the excessive phenomenon of soup boiling can be occurred because the user is careless or the food own characteristic.At this moment, soup will flow into above the matrix 2 of conditioning chamber, flows into matrix 2 bottoms along the through hole 3a that forms on the matrix 2, and access to plant is in the turntable motor 10 of matrix 2 bottoms.

Existing turntable motor structure is as Fig. 2 a (plane), Fig. 2 b (left view), Fig. 2 c (stereogram) shown in: have cover 11 with outer cover body 12, attaching has plug 14 on the cover body 12 outside, also have to be used for the flange 13 on matrix 2, fixed.Be formed with the hole 15 of several gear shafts (not illustrating among the figure) of fixed electrical machinery inside on 11 at lid, the also outstanding axle 16 that is connected with fixing tool 3 that is formed with.

But as seen from the figure, it is littler than the outer wall 12a of outer cover body 12 to cover 11 external diameters, installs the top of cover body 12 outside, and the upper end of cover outer wall 12a is provided with a plurality of being used for fixing and covers 11 fixedly card 17 outside, is provided with in lid 11 outer ends and fixing 17 recesses that cooperate 18 that block.

Lid 11 is actually and embeds in the outer cover 12, and shown in Fig. 2 C, the outer wall 12a of outer cover upper end outwards expansion is crooked, so increase manufacturing process.

Existing turntable motor with this structure, when soup entered, soup accumulated in recess 18 places, by cover 11 and outer cover outer wall 12a between the slit flow into motor internal.Because the inflow of soup, make because of containing salt in the soup motor coil mashed disconnected, foreign matter enters reduction gearing, gear is stuck and phenomenon such as breakage will take place.

For overcoming the above problems, have and use rubber blanket, but thermal deformation takes place in easily, also can increase manufacturing cost.

Problem in the prior art proposes the utility model in order to solve just, and its purpose is to provide a kind of can preventing to flow into turntable motor and damage the turntable motor outer cover of turntable motor from the moisture that the conditioning dish flows out.

For realizing above purpose, the utility model rotary desk of microwave oven motor comprises with outer cover:

Outer cover body 22, it has the outer cover matrix and is vertically prolonged and the outer wall 22a that forms and by the extension 22b of outer wall 22a upper end extend outwards by the outer cover matrix, is formed with plurality of holes 31 in the specific location of this extension;

Lid 21, the flange portion 27 on top that it has the extension 22b of the outer wall 22a that is positioned at outer cover body 22 is formed with outstanding on flange portion 27 downwards and expophthalmos portion 30 in the plurality of holes 31 cover body 22 outside the embedding.

In utility model, lid protrudes in outer cover body 22 above 21 and is formed with on the micro-wave oven body the fixedly mounting flange 23 of the band screw of usefulness outward, the extension 22b of cover body outside mounting flange 23 downsides do not have to form is formed with protuberance 21b along the coil cap 24 length direction loam cakes 11 of body 22.

Following with reference to description of drawings the utility model embodiment once.

Fig. 3 a, 3b, 3c be respectively the utility model micro-wave oven with the plane of turntable motor, left view, stereogram, respectively with Fig. 2 a, 2b, the 2c mapping mutually of prior art.Turntable motor is by

outer cover body

22 and 21 clads of lid.

By Fig. 3 a as seen, the upper end of outer cover body outer wall 22a cannot see.Lid 21 has flange portion 27, and its detailed sectional drawing-Fig. 4 a by A portion can clearly illustrate.

Flange portion 27, shown in Fig. 4 a, end is bent downwardly, and this makes the soup can be to dirty.

Above the lid 21, be positioned at flange portion 27 inboards and be provided with a plurality of outstanding downwards expophthalmos portions 30.Outer cover body outer wall 22a upper end extend outwards engages with the expophthalmos portion 27 of lid 21, and the expophthalmos portion 30 with lid 21 on the extension 22b of outer wall 22a forms porose 31 in the mapping position mutually.As shown in the figure, expophthalmos portion 30 upward charges into downwards in the hole 31 of formation by the extension 22b of outer wall 22a, as the holding appliance crimping, outer cover body 22 and lid 21 is mutually permanently connected.

Always, lid is little with the contact area of outer cover body, and according to the utility model, both contacts area are big, and its advantage is can thoroughly prevent owing to produce the soup inflow that capillarity is brought between fine slit.

When the hole 31 of the extension 22b that forms outer wall 22a, make the upper diameter in hole smaller, and lower diameter is bigger, when crimping expophthalmos portion 30, it makes lid firmer with fixing of outer cover body to the lateral expansion in hole like this.

In addition, on the certain position of lid 21 ends, be provided with two mounting flanges 23.This mounting flange 23 has and is convenient to outer cover is screwed screw hole on the micro-wave oven body shown in Fig. 4 b.Here, Gu Ding flange 23 downsides are provided with the extension 22b of the outer wall 22a that forms outer cover body 22.This be for avoiding since the capillarity soup from lid and outer cover body contact-making surface gap inflow motor internal.Because if the mounting flange of lid and outer cover body extension are connect.Touch, soup can flow into this part that contacts along attachment screw, so because capillarity just might flow into motor internal.

In the past, flange 23 was fixed on outer cover body outer wall 22a and went up formation, and in the present embodiment, it forms on lid 21.

Other as fixing hole 25, intercalation part 24 etc. with the same in the past, the Therefore, omited explanation.

In fact be flat shape according to rotary desk of microwave oven motor of the present utility model with the lid of outer cover, there is not neutral gear between the outer wall of lid and outer cover, the phenomenon of rotary tray motor inside can not appear flowing into from the soup that micro-wave oven conditioning dish overflows, so can strengthen the security and the durability of turntable motor.

More than the utility model is described, but it only is a kind of illustration, it should have the possibility of various distortion and variation, accessory rights requires to be appreciated that these distortion and changes and also should belong to protection domain of the present utility model.
