Abstract

A condenser is composed of a hollow body which can basically flow through humid air from the bottom to the top, and can be flushed by tap water via a valve which can be opened and closed at the inlet position so as to achieve cooling purpose. The input water is supplied by a bell cover (11) to improve functions of condensation and removing villi, and a tangential input connection pipe 12 is arranged on the bell cover. Water spirally flows out at a water outlet 15 and forms a large fan shape which is greater than 180 DEG C and is composed of a plurality of fog drops, an inner cavity of the hollow body is filled with the water and part of the water flows down along the inner wall of the hollow body to remove the villi by flushing.

Description

Clothes drying washer

The present invention relates to a kind of washing machine that disposes for drying that is provided with condenser, wherein condenser mainly is made up of the ducted body of the wet process air that can circulate from bottom to top, but and for the cooling purpose moistening with running water via the valve of switch in import department.

By Deutsche Bundespatent prospectus DE 4104760 known described a kind of like this clothes drying washers.Set therein a kind of condenser has been proved to be and has had such problem: the drying that no matter carries out in the process air is in the stage, still in alkali lye in the washing process, fine hair in the laundry logistics of institute's carrier band all can be scattered on the inwall of condenser, and after the drying stage finishes, can dry.Especially owing to the cause of people, cooling water flow is restricted to as far as possible little value and facilitates this kind danger for the fresh cooling water of saving.Though can make every effort to reach the cooling water distribution of broad as far as possible area by measure suitable, especially condensation hollow body structures aspect, but therefore can not utilize whole wainscot wall area territory equably, also can be scattered by villous in this wainscot wall area territory, and in addition, also have a large amount of fine hair parts to flow through condenser together with the process air, until entering pressure fan, fine hair finally is scattered in the pressure fan then.

The task that the present invention is rely to the basis is, improve the washing machine described in the foreword, so that no matter can both wash out the fine hair that is scattered during still at drying during in washing in the condenser, simultaneously, can also carry out condensation process, thereby make the required water yield of flushing fine hair keep fewly as much as possible.These two kinds of functions should realize via same water channel.

According to the present invention, this task is finished like this: the place was right after before the ducted body middle outlet at the import ducted body, be provided with at least near the tubular inwall be provided with the tangential entrance branch that is connected.Whereby, the water of inflow shape and fan-shapedly flow out in the shape of a spiral in bell jar from outlet with roomy.So the water that flows into arrives the whole wall portion of ducted body, and fine hair is rinsed out.For this reason, the required water yield then can keep seldom.

Especially the tool advantage is that the present invention can further so develop: directly in delivery port bottom a shock plate is set, it is the bell each side that is assigned to flushing water or cooling water.Whereby, also can make condenser ducted body inner wall surface partly wash away more evenly, fine hair and this surface portion just might be scattered.In addition, bell-shaped profile can also play the effect that cooling water and process air flow are fully contacted, thereby the fine hair that flows with the process air is arrived at less than pressure fan.

The development that other is useful can be learned by the following explanation of the embodiment of the invention shown in dependent claims 4-8 and the accompanying drawing.

Accompanying drawing illustrates,

Fig. 1 is the side view of the set transparent condenser ducted body of the present invention,

Fig. 2 is the dorsal view of above-mentioned ducted body;

Fig. 3 is the longitudinal section of the water inlet of unit III shown in the Fig. 1 that is cut by III-III hatching among Fig. 4,

Fig. 4 is the cross-sectional view along the water inlet of IV-IV line cutting among Fig. 3.

The shape of condenser ducted body is decided on existing free space in the washing machine, and has moist process air to flow through basically from bottom to top from air inlet 2 to the pressure fan connecting hole 3 that is located at the bottom that is located at the bottom.This is shown by hollow big arrow.Be located at following air inlet 2 and connect with unshowned laundry soda liquid container, and equally also as the outlet from last input and flushing water of ducted body itself, using or cooling water.This water pumps from alkali liquor container with lye pump usually.

Import 4 comprises a unshowned electromagnetic valve, and leads to shock plate 5 via bell jar 11, and the water that flows into is become bell-shaped profile in the condenser hollow space.Water evenly distributes with atomize, and some inwall along ducted body 1 flows to air inlet or water discharge outlet 2 downwards.

For the humidity that makes the condensation process air is normal, for instance, via import 4 intermittent entry cooling waters.Therefore, supplying water intermittently, the condenser inner chamber can not become dry, thereby neither fine hair is not washed in condensation yet, and a storage chamber 8 can be set on the top of water inlet 4, and the retaining wall 9 of this storage chamber is provided with a plurality of water discharge outlet 10.The size of these water discharge outlet should be able to make the cooling water that is held reduce the rate of outflow in corresponding to the time intermittently of supplying water.Simultaneously, all water discharge outlet 10 as in the embodiment shown in the figures, can be located at the side of retaining wall 9 or only be located at downside, perhaps are the shape of hole.Storage chamber 8 also can be different from shown in the accompanying drawing, is located at around the ducted body cross section with annular or U-shaped, and the direction that flows facing to the process air from three or four sides of its water discharge outlet.To the profile of ducted body and storage chamber play a decisive role mainly be in washing machine this condenser the actual conditions on the local location that should be provided with.

Unshowned valve in this accompanying drawing of for example big water through-current capacity is set up in the fresh water import, to wash out fine hair.Because condensation only needs less water through-current capacity, therefore for condensation process, this valve can be open-minded off and on.Described shock plate under bell jar 11 force a part of fresh water along wall to dirty.Even in condensation process, it also rinses out the fine hair on the wall.Because also atomizing of the violent rotation of a part of cooling water, so tomentum washes off from the process air especially effectively, and condensation effect also is improved.When the intermittence that supplies water was paused, the storage of water in the storage chamber 8 was just taken over the work of flushing ducted body 1 inwall.

The general such formation of condenser ducted body: water from highest point footpath by shock plate at least in part along all walls to dirty.That produce in the fine hair flushing process and pump with lye pump at once through the water that air inlet 2 flows into the washing machine alkali liquor container, thus can make fine hair not arrive washing clothes.Then, these fine hair can be removed simultaneously with the water that need pump.

Even because fine hair also splits away off from washing clothes when washing, and is taken in the condenser by detergent foam, therefore, suitable is in the laundry stage, for example in each cleaning procedure, to wash condenser off and on.Beneficially, condenser flushing only in alkali liquor container, also be water level when not reaching the low water level that reaches condenser air inlet 2, also promptly for example when each cleaning procedure finishes, just carry out.Beneficially, when infeeding fresh water, make pressure fan and pump operation.

Whereby, the top of condenser ducted body is through directly washing hollow body wall portion and vertical component effect, because of the rotation of water removes floss removing.Under situation about evenly using automatically, in laundry processes, each water yield seldom that only needs promptly is enough to flush away fine hair.

A water inlet valve and a flexible pipe of linking the condenser water inlet are only required in above-mentioned these measures.Since the control of water through-current capacity can by different time length ground or off and on Open valve finish, so also just need not be such as other parts second valve.

According to the present invention, because water vapour condenses from the process air, and fine hair is owing to the particular arrangement to condenser ducted body 1 cooling water inlet 4 on the other hand, effect is improved on the one hand.Fig. 3 and Fig. 4 inquire into as more detailed this.Bell jar 11 has a tangential arm, and it is contained in downwards on the horizontal walls 13 on ducted body 1 top highlightedly.This bell jar is decided by the interior shape of leg portion of institute, also can be highlightedly or surfacing ground install.The inwall 14 of this bell jar 11 is a cylindrical shape.If but inwall because of shape produces any advantage, for example increase the friction of water to inwall through centrifugation accelerates, then also can be to the tapered expansion of end.Bell jar 11 stops at outlet 15 places downwards, this outlet at distance B place by one along shown in the perpendicular cuts-shock plate 5 covers.This shock plate 5 post 16 of being installed in bell jar 11 lumen centers supports simultaneously, and its diameter is identical with bell jar 11.

This layout cause compare with outlet 15 water that more approaching bottom 17 flows in the shape of a spiral shape move, and with being wide fan-shaped outflow at this moment the annular slot 18 of this rotation between Jie's bell jar 11 lower edges and shock plate 5, be sprayed into a large amount of droplet beams 19, be full of ducted body and against the sedimentation quite lentamente of process air.The maximum surface area that therefore the droplet beam has is compared the most effective for condensation effect with institute's water content in the process air.In addition, because water is distributed to each place that fine hair at all can not sedimentation in this way, therefore, the mode of this minute water distribution is best suited for the fine hair flushing process.

Even only on a certain position of annular gap 18 outlets, produce the blind area S (Fig. 4) that droplet limit beam 20 can not and reach.The position of this blind area depends primarily on the position of entrance sleeve mouth, the width B of annular gap, the diameter of inwall 14 and the size that tangential entry is taken over 12 sectional areas.For instance, what proved main arrangement criterion already is, by the annular gap discharge area that width determined of shock plate 5 and annular gap 18 should be entrance sleeve 12 sectional area 2-3 doubly.Whereby, also determined the approach etc. of bell jar 11 inside spin shape water jets 21.Described blind area S is facing to pressure fan interface 3 (Fig. 1).In this way, can avoid water droplet directly to spray into pressure fan, and the danger of water droplet companion is also thoroughly eliminated.

Therefore, those mentioned purposes of front just are able to best the realization, but also must note considering the volume of bell jar 11, brake on inwall 14 based on the water of input this moment and since the unstability of annular gap 18 just no longer be restricted.
