Description

Clothesdrier including heat pump system

Technical field

It include that there is improved air stream in the pedestal of the clothesdrier the present invention relates to a kind of clothesdrier Heat pump system.

Background of invention

Heat pump techniques in clothesdrier are the most efficient way of current drying clothes in terms of energy consumption.In clothing In the heat pump system of drying machine, processing air stream flows in closed processing airflow circuit.Further, the heat pump system Including closed refrigerant circuit.Processing air stream is mobile by main fan, passes through clothing room (is preferably formed as rotatable Laundry drum) and moisture removal is removed from wet clothes there.Then, the processing air stream in evaporator be cooled and Dehumidifying is heated within the condenser and re-injects in laundry drum.

The refrigerant be by compressor compresses, within the condenser condensation, in expansion device expand and then evaporating It is vaporized in device.

Therefore, the condenser and evaporator are the components of the processing airflow circuit and refrigerant circuit.The condenser And evaporator is the heat exchanger between the processing airflow circuit and refrigerant circuit.

In general, these components of heat pump system are placed in the pedestal of clothesdrier.The pedestal of clothesdrier is A part of shell, the shell further include the wall being substantially perpendicularly supported from the pedestal other than the pedestal, such as before Wall and rear wall and multiple lateral walls.Clothing is introduced so as to be rotatably supported on this outer for this dry roller In shell.Specifically, compressor, evaporator and condenser are arranged in the pedestal below laundry drum.Handle air stream The air conduit in circuit has to pass through the pedestal of the drying machine, to take humid air to evaporator and condenser in future Dry air be introduced back into roller.Conduit in the pedestal can be by by two shell (upper housings in advantageous embodiment Portion and bottom housing part) it comes together to be formed, the two parts form the pedestal.

Fig. 7 illustrates the top view of the pedestal of the opening of the clothesdrier including heat pump system according to prior art. Compressor 140, evaporator 160, condenser 180, main fan 200 and motor 220 are arranged in the lower part 100 of the pedestal.It steams Hair device 160 and condenser 180 are placed in parallel in straight pedestal processing air conduit.In addition, leaving the air of condenser 180 Stream must carry out two substantially 90 ° of turning, to reach the outlet of pedestal processing air conduit in the pedestal, the main wind Fan is located at here, the two 90 ° turnings are connected again by straight pedestal processing air conduit.

Such angle in processing airflow circuit causes pressure drop and turbulent fluctuation, to increase energy consumption and make an uproar Sound.In fact, such pedestal processing air conduit is far from reaching optimum air aerodynamic shape, this latter is will to flow over The shape that air drag in journey greatly reduces.

However, in order to have the pedestal for avoiding zig zag and angle to handle air conduit, these heat exchangers must be In other words the chassis interior relocates, pedestal processing air conduit (wherein, handles air to flow to from these heat exchangers The main fan) " more spaces " is needed so that it can leniently bend to avoid 90 ° of anxious turnings.

Applicant is recognized by many experiments, can limit threshold distance, that is, the pedestal handles air conduit to incite somebody to action Processing air from these heat exchangers be directed to the pedestal processing air conduit main fan and " workable " distance, be higher than should Threshold distance is then likely to form " mild " curve of pedestal processing air conduit.

It is leaned on as far as possible by reducing the space that occupies of heat exchanger and/or moving on to heat exchanger, evaporator and condenser The wall opposite with the processing outlet of air of pedestal of nearly shell can obtain in pedestal for handling the such of air conduit Exceptional space, these heat exchangers are usually one of heavy element in pedestal.However, first solution can reduce heat The efficiency of pumping system, because there are too narrow heat exchange surfaces；It is therefore contemplated that the solution is not optimal.Second solves Scheme also has further limitation, as detailed below.

Drumdrier generally include for collect the villus separated in the clothing for needing to be handled in the drying process or The filter system of velveteen.Typically, prior art drumdrier provides the door of the neighbouring drumdrier (door is Close) filter system so as to can be easy to pass in and out the filter system.It is provided in drumdrier and enters filtering The air stream of device system.The villus or velveteen for having the air stream in clothing to be dried to carry are filtered out by filter system, The air for leaving filter system is made to there is no velveteen or villus in this way.Such air can be heated again and It is transported in the clothing process chamber of drumdrier.By heat exchanger drying and air is heated, these heat exchangers are being located Manage the downstream for being located at filter element in the flow path of air.Due to handling the structure of air pipeline, air is handled along one party Filter is flowed through to (such as substantially vertical direction), then since heat exchanger is located at the fact in pedestal, processing air changes It changes direction to initially enter refrigerant evaporator subsequently into refrigerant condenser.

Therefore, if evaporator it is mobile if too close filter or evaporator hits filter and before The further translational motion of wall will hinder a possibility that being maintained at filter on its correct position, or in filter size It is smaller evaporator is located at below filter in the case where, processing air will hit the top of evaporator rather than evaporate The entrance of device reduces evaporator so that a part of the length of evaporator will not suitably be passed through by air, and final Effective heat exchange surface.In addition, it must be changed by impinging upon the processing air at the top of evaporator in order to cycle through the roller Thus flow direction in evaporator causes the mobile excessive place of the fan provided to generate mass air flow energy loss Manage air.

With the name of same applicant, EP 2581488 discloses a different solution, which is related to A kind of clothesdrier with the heat pump system for including evaporator and condenser.The heat pump system includes airflow line, the gas Flow tube road is arranged to that air-flow is allowed to pass through laundry drum, evaporator and condenser.At least one filter element is arranged at this The upstream of evaporator.The evaporator is arranged at the lower section of filter.

In order to which the evaporator to be arranged in the lower section of filter, it is necessary to use very small filter, which is going It is not effective in terms of except all velveteens.In addition, the evaporator also has very limited size, because its import must face The position of filter and outlet is determined by the thickness of pedestal.Therefore once again, being obtained in such evaporator quite Small heat exchange surface.

The object of the present invention is to provide a kind of clothesdriers with heat pump system, wherein handle air stream flowing, Processing air stream especially in the pedestal of the clothesdrier, which flows, to be improved.

Core of the invention be the on the one hand arrangement of the evaporator and condenser of heat pump system on the inside of the pedestal with The combination of the positioning of the import of another aspect roller gas exhaust treatment air pipeline.Due to being mutually located for those components, handling May have in the pedestal of air conduit this " than usually much bigger " to set a distance.By keep at least the above threshold value away from From from the position of the usual position change evaporator of prior art drying machine and at the same time keeping the rolling of evaporator and just size Cylinder exhaust gas intake port allows to carry out efficient heat exchange and filtering, and the processing air of the condenser to the pan outlet, which flows, to be changed It is kind.

Surface can have the projection on perpendicular and horizontal plane, these projections are surfaces.If surface itself It is that vertically or horizontally, the projection on horizontal plane or perpendicular is a line respectively.If surface is limited to vertically Plane ratio is in the broader projection of horizontal plane, then that is the surface has " broader vertical projection ".

In the same way, section can have the projection on perpendicular and horizontal plane, these projections are lines.Such as Fruit section itself is that vertically or horizontally, the projection on horizontal plane or perpendicular is a point respectively.If section Perpendicular ratio is limited in the longer projection of horizontal plane, then that is the section has " longer vertical projection ".

Preferably, the rear wall and antetheca are mounted on the pedestal of the drying machine.Even further preferably, in addition the shell includes Wall, such as multiple lateral walls and a roof.

In the top view of the drying machine, pedestal is considered through the rotation axis of the roller (or the axis Projection of the line on the base plane) by " divisions " at two longitudinal direction half portions.No matter the axis is horizontal (to be accordingly parallel to bottom Seat plane (X, Y)) or relative to the latter be it is inclined, in the top view of the pedestal, the projection of cylinder axis divides pedestal At two half-unit, first or left longitudinal half portion and second or right longitudinal half portion.In other words, take one perpendicular to base plane simultaneously And by the plane of cylinder rotational axis (being generally overlapped with the center line of pedestal), this plane is almost by pedestal cutting at two A longitudinal direction half portion.This plane (referred to as the first plane) is defined when being parallel to the plane cutting of (X, Y) plane is pushing up The dividing line that pedestal is divided into two in view.

The two half portions need not be identical.In other words, the first and second half portions refer to pedestal, relative to warp Cross the rotation axis of roller and perpendicular to " right side " and " left side " part for the above-mentioned plane of base plane (the first plane).In this way Projection of the rotation axis on pedestal therefore may deviate the center line of pedestal.Preferably, the rotation of the center line and the roller The projection of shaft axis is overlapped.

The layout of heat pump system in the pedestal of drying machine of the invention is as follows.

First heat exchanger and second heat exchanger are located in base vent pipeline and its most of volume is in pedestal Extend in first longitudinal direction half portion, such as their most of volume is located substantially on the left side of the rotation axis of roller.Heat exchange Device can be completely contained in the first longitudinal direction half portion of the pedestal or its partial volume, fraction volume can also be at the bottoms Extend in the second longitudinal direction half portion of seat.Moreover, at least most of area for the outlet that processing air leaves from condenser is position In in the first longitudinal direction half portion of pedestal.

On the other hand, from pedestal is gone out, outlet is located in the second longitudinal direction half portion of pedestal processing air, that is, positioned at rolling In pedestal half portion on the right of the rotation axis of cylinder.Preferably, which realized in the rear portion of pedestal, that is, towards The rear wall of cabinet.Therefore, it is directed to base exterior in order to which air will be handled, first longitudinal direction half of the pedestal conduit portion from pedestal Portion, the outlet that pedestal is extended to since the outlet of condenser, and reach the second longitudinal direction half portion of pedestal.Due to heat pump system This geometry and layout that the positioning of each element of system in the base is forced, although the best sky of conduit guidance air Aerodynamics scheme will be straight catheter, but the conduit portion includes at least one " elbow " or " turning ".

Preferably, the pedestal processing air outlet slit in front of or near, located and be easy to for example blow from pedestal to roller The main fan of processing air in the processing air loop.The main fan includes impeller, which rotates so that processing air moves It is dynamic.

Preferably, the import of roller gas exhaust treatment air pipeline be formed at the aperture formed to pass in and out roller and More preferably at the lower edge in aperture.

The roller gas exhaust treatment air pipeline preferably includes the first substantially vertical part or has broader vertical throwing The part of shadow.This first part of the roller gas exhaust treatment air pipeline is preferably partially formed in the pedestal.

The roller gas exhaust treatment air pipeline preferably includes second part, it is therefore preferable to the second substantial horizontal part or Part with broader vertical projection.Evaporator and condenser are preferably respectively positioned in this second part, the second part Terminate since one end of first part and at the outlet of the condenser.

First part includes import, and the exhaust from roller enters the import.The import limits the import for surrounding the import Edge.The inlet edge is the import " boundary ", and its beginning for defining the roller gas exhaust treatment air pipeline.It is preferred that Ground, the inlet edge have vertical component part and horizontal component part, in other words, along edge surface perpendicular and In the projection of horizontal plane, vertical curve and level curve are limited respectively, which surrounds region that may be different from zero.

The edge limited front-end and back-end.The rear end at the edge is the point nearest with the rear portion of shell at the edge, i.e., most Close to the rear wall of the shell.Front end is the nearest point in the front of the edge and shell, i.e., near the antetheca of the shell.At edge In projection in a horizontal plane, what both ends were the readily visible.

For example, being inserted into the roller gas exhaust treatment air pipeline if had from the filter of the import ventilative grid outstanding In；Such grid limits the newly imported edge with outer boundary.If filter is inserted in import and is equally applicable, the import With making the outwardly projecting part of the import.The boundary of the filter becomes inlet edge, which is and comes from roller Processing air contact first part.Further similarly, the boundary of the inlet edge can be limited by ventilative grid, should Ventilative grid is mounted to be independently and separately from the part of processing air filter.

The edge is thus delimited by inner plane and outerplanar in one direction, which is divided into perpendicular to by pedestal First plane of two half-unit and the rear end for passing through the edge, the outerplanar are divided into the of two half-unit perpendicular to by pedestal One plane and the front end for passing through the edge.Inner plane and outerplanar are perpendiculars.In other words, that two planar water level lands are fixed The boundary space, within this space, processing air enter the roller gas exhaust treatment air pipeline.

There are enough spaces in order to ensure handling air conduit, particularly its above-mentioned bending in pedestal, according to the present invention, steams A part of hair device is located at the lower section of the rear end at the edge of import.

This means, takes the interior perpendicular across the rear end at the edge of the import, this interior perpendicular also steam by cutting Send out a part of device.This perpendicular (perpendicular in referred to as) can be parallel to the antetheca of shell in a preferred embodiment.

To which evaporator is divided into two parts by the interior perpendicular, and one of part is located at roller gas exhaust treatment The lower section of the rear end at the edge of the import of air filter.

However, the front end that the evaporator does not extend up to the edge is located at the lower section of entire import, because in this structure In type, processing air cannot hit the inlet surface of evaporator with correct mode, i.e., cannot be along substantially horizontal orientation or edge Hit the inlet surface of evaporator in direction with longer horizontal component part.If the evaporator is located at the lower section of entire import Or in its most lower section, then enter roller gas exhaust treatment air pipeline import processing air will from top rather than Evaporator is hit at its inlet surface.As described above, the inlet surface of the evaporator is substantially vertical or at least has wider Vertical component part, thus in order to enter evaporator from its import, which needs basically vertical direction " turning " To substantially horizontal orientation.If processing air stream from top shock evaporator, here it is possible, but its substantially At vertical inlet surface, or at least only this air stream of small part hits evaporator except its inlet surface.

For this reason, preferably evaporator has the part being located at below roller.By this method, evaporator is located to the greatest extent Processing air may be made correctly to flow into roller gas exhaust treatment air pipeline without obstruction simultaneously close to the antetheca of shell.
