Two top plates 43 are connected with the upper edge of the upper edge of outer panel 42 and interior plate 41, the second top plate 43, interior plate 41 and outside
The connection of plate 42 forms runner.It follows that there are two pump chambers for the heat pump tool in the present embodiment, except the pump of the first pump case 1 formation
Other than chamber, there are also the big heating pump chambers that the second pump case 4 and heating tube 3 are formed, or referred to as water pump chamber outside it.
It is intracavitary to enter above-mentioned water pump after water flow is discharged from the first outlet 12 of the first pump case 1, then from the second pump case 4
The discharge of second water outlet, here, the second pump case 4 can be designed to the form of spiral case, in order to improve the waterpower of water outlet water flow
Efficiency.And resulting double pump chamber dual channel structure and flow-guiding structure 5, so that the circulating water flow in the heat pump of dish-washing machine
Water outlet is more slowly uniform, so that so that dish-washing machine is increased heating power becomes to be more easier, avoids hydraulic loss and energy damage
Consumption.Meanwhile water flow can be made by the runner of this relatively optimization, and the volume of pump chamber size in other words will not be increased, thus
Integrally-built size in dish-washing machine is saved, and then the structure optimization that can be dish-washing machine to a certain extent is more easier.
Certainly, the second pump case, which does not limit to, belongs to fluid force when impeller 4 is centrifugal impeller with the runner of spiral case form
Ground in range is learned, runner should be involute in form, so the runner of scroll casing type meets the kinetic characteristic of its water flow.But
When impeller 4 is axial wheel, the first pump case 1 and the second pump case 2 can be designed as barreled runner etc. and be more suitble to axis stream leaf
The runner of wheel, it is generally the case that the washing pump in dish-washing machine is all centrifugal water pump, but the invention is not limited to

In other words, the pipeline that first entrance 11 is extended is exactly water inlet pipe 7, and water inlet pipe 7 can be the plastic cement such as PE or PC
Material is also possible to metal material, and its form that can be multistage connection, is also possible to the siphunculus of an one.Heating
Enter water in pump, is all to be directly entered by water inlet pipe 7 inside the pump chamber of first pump case 1 formation, then pass through centrifugal impeller 2
Rotation obtains stronger centrifugal force and spiral, to be thrown out of in the water outlet or through-hole of the first pump case 1.
As shown in Figures 1 to 4, heating tube 3 is thick-film heating structure.Under normal conditions, thick-film heating pipe 3 uses screen printing
Brush technology is respectively the insulating medium layer printed on substrate pipe, resistive layer, conductor layer, protection glaze layer etc. from inside to outside, then is led to
High temperature sintering is crossed to form.As its name suggests, because of the structure of its tubbiness, as natural water channel, the flowing water in channel can be made to pass through
360 degree of heating is crossed, is integrally heated relatively uniform, heating efficiency will not be made to reduce because heater surfaces generate a large amount of bubbles.
And since heat can conduct away in time, so entire heat-generating pipe surface temperature is not high, open fire will not be caused.And safety
It is good, long service life.
From the foregoing, it can be seen that heat pump provided by the invention, not only has the advantages that all of thick-film heating, it is often more important that simultaneous
The raising of the complete and heating efficiency of flow passage structure has been cared for, while having also assured the applicability of product size, and structurally reasonable,
