Background technology

Fig. 1 is the structural representation of drying-type conventional washer.

As shown in Figure 1: we know, the oven dry circulatory system of drying type drum washing machine comprises outer bucket 1, interior bucket 2, drying channel 3, centrifugal fan 4, air heater 5 and condenser pipe 6, wherein, interior bucket 2 places the inside of outer bucket 1, have certain clearance between the two, drying channel 3 places the top of outer bucket 1, and its air inlet a communicates with the opening of interior bucket 2 and outer bucket 2, also be provided with centrifugal fan 4 and air heater 5 on drying channel 3, condenser pipe 6 then connects drying channel 3 and outer bucket 1.

Fig. 2 is the front cross-sectional view of the oven dry circulatory system of traditional drying-type conventional washer; Fig. 3 is the side sectional view of the oven dry circulatory system of traditional drying-type conventional washer;

As shown in Figures 2 and 3: when washing machine carries out drying operation, heated air is under the effect of centrifugal blower 4 in the drying channel 3, enter the outer bucket 1 of washing machine by the air inlet a of drying channel 3, a hot-air part is moved in the gap between bucket 1 and the interior bucket 2 outside, M as shown in Figures 2 and 3, N, the P air-flow, promptly along the circumferentially mobile left M air-flow in interior bucket 2 and outer bucket 1 gap, circumferentially mobile to the right N air-flow along interior bucket 2 and outer bucket 1 gap, and along interior bucket 2 and outer bucket 1 gap the outside P air-flow of barrel 1 rear flow, another part enters interior bucket 2 by the hole of interior bucket 2 and the gap of inside and outside bucket front end, as 2 and O air-flow shown in Figure 3, hot-air carries out indirectly or directly heating clothing, make the moisture content in the clothing become water vapour, while is along with hot blast flows, be to cross after at the bottom of M air-flow and N air-flow flow to barrel, together with the O air-flow after overflowing from the hole of interior bucket 2 on a small quantity, the common R air-flow that forms, the R air-flow is brought water vapour into condensation channel 6, condensed water vapour liquefy water is discharged outside the washing machine, thereby reaches drying effect.

In this cyclic process, the O air-flow of bucket 2 inside can more effectively heat and take away moisture content in entering to clothing, therefore, drying efficiency is high more more at most for the O air-flow of bucket 2 inside in entering, and in the oven dry circulatory system of traditional drying type drum washing machine, the oven dry hot blast behind the bucket 1, runs into inner barrel wall and stops outside air inlet a enters, and airflow direction changes, and random motion, produce M as shown, N, O, four kinds of main air-flows of P, wherein the air-flow that oven dry is played a major role is the O air-flow, but in practice, because inside and outside bucket gap is big, M, N, the shared ratio of P air-flow is far longer than the O air-flow, can not effectively take away steam, and drying efficiency is low.

The utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide effectively oven dry air-flow of a kind of increase, improves the air intake flow guide system of the drying type drum washing machine of drying efficiency.

The utility model is achieved through the following technical solutions:

A kind of air intake flow guide system of drying type drum washing machine, comprise outer bucket, interior bucket, drying channel, centrifugal fan, air heater and condenser pipe, wherein, interior bucket places the inside of outer bucket, has certain clearance between the two, drying channel places the top of outer bucket, its air inlet communicates with the opening of interior bucket and outer bucket, on drying channel, also be provided with centrifugal fan and air heater, condenser pipe then connects drying channel and outer bucket, it is characterized in that, be provided with many water conservancy diversion ribs near the air inlet place on Tong the inwall outside, described water conservancy diversion rib is structure as a whole with outer bucket.

Above-mentioned water conservancy diversion rib comprises along the circumferential water conservancy diversion rib of outer bucket inwall circumferencial direction setting and the radially water conservancy diversion rib that radially is provided with along outer bucket inwall, and radially the water conservancy diversion rib is 4, is symmetricly set on the both sides of air inlet respectively.

In addition, on the inwall at the bucket bucket end the circumferential water conservancy diversion rib that is provided with along outer bucket inwall circumferencial direction is set also outside.

The beneficial effects of the utility model are: many water conservancy diversion ribs are set near the air inlet place on the inwall of the utility model by bucket outside, the flow direction that can effectively stop M, N, P air-flow, make the O air-flow of bucket in entering more concentrated and smooth, and under the effect of centrifugal blower, can form low-pressure area in the bottom of interior bucket, force gas by the inner space that flows out to interior bucket bottom of interior bucket, enter condensation channel again, improve drying efficiency greatly.
