Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model Limitation.

The hot air apparatus 100 of the dish-washing machine of the utility model embodiment is described below with reference to Fig. 1-Fig. 3.

According to a kind of hot air apparatus 100 of dish-washing machine of the utility model embodiment, as shown in Figure 1, comprising: hot wind shell 10, centrifugal wind wheel 20, heat generating member 30.

Wherein, the air-inlet cavity being located along the same line, heating chamber and air-out chamber, hot wind are successively limited in hot wind shell 10 Shell 10 is equipped with air inlet 101, air outlet 102, and air inlet 101 and air outlet 102 are located at the same side of hot wind shell 10 On, heat generating member 30 is located in heating chamber.Collinear three cavitys of the utility model are interconnected, when air-flow passes through each cavity When, without turning to, air-flow windage is smaller.Air inlet 101 and air outlet 102 are on same side, in this way, hot air apparatus 100 It can be mounted directly on dish-washing machine, hot air apparatus 100 connects the liner of dish-washing machine woth no need to be reconfigured bend pipe.

Centrifugal wind wheel 20 is located in air-inlet cavity, and centrifugal wind wheel 20 provides driving force for the sucking of air-flow and guiding.Centrifugation The air intake of wind wheel 20 is arranged towards air inlet 101, and the outlet air end of centrifugal wind wheel 20 is arranged towards heating chamber.Centrifugal wind wheel 20 will Air inlet 101 and air-inlet cavity, heating chamber are connected together, and strengthen the air stream drives power from air inlet 101 to heating chamber, make gas For stream from 101 fast steering of air inlet into heating chamber, intake is big, and air intake efficiency is high.

What needs to be explained here is that the air-flow in internal cavity of bowl washer enters hot air apparatus 100, inevitably an air-flow is needed to turn To process.If centrifugal wind wheel 20 is replaced with axial-flow windwheel, using bend pipe realize air inlet steering, then air-flow be exactly Being rebuffed when air inlet, (guiding of bend pipe) realization turns to afterwards, and turning path is big at this time, and windage energy consumption is also big.And the utility model is real It applies in example, by the way that centrifugal wind wheel 20 is arranged in air inlet, air-flow is automatically performed during being sucked, being pumped out by centrifugal wind wheel 20 It turns to, not only air-flow turning path is short, invisible waste is small for the steering realized by centrifugal wind wheel 20, but also 20 air quantity of centrifugal wind wheel is big, gas The heat exchange efficiency for flowing through heat generating member is high, and the heat blow of hot air apparatus 100 is apart from farther.In addition, the structure of centrifugal wind wheel 20, has It is made into flat tubular conducive to by 10 entirety of hot wind shell, is occupied little space, and low noise.
