Description
Technical Field
The invention relates to a spray unit for spraying a spray mist into a washing drum of a laundry treatment appliance. The invention further relates to a laundry treatment appliance having at least one support shield, a washing drum and at least one spray unit arranged on the support shield for spraying a spray mist into the washing drum.
Background
Laundry treatment appliances may be equipped with a function for de-wrinkling or smoothing the laundry. In this case, during the rotation of the washing drum, moisture is applied to the crumpled laundry located in the washing drum. In this case, the odor of the laundry can be simultaneously reduced in the passing-through laundry. A corresponding laundry treatment appliance is known, for example, from european patent EP 2 504 482 B1.
Disclosure of Invention
The object of the present invention is to simplify and reduce the effort for maintaining a laundry treatment appliance of the type mentioned at the outset.
Advantageous configurations are described in the following description and the drawings, wherein said configurations can each achieve further improved, in particular also preferred or advantageous aspects of the invention, individually or in different combinations with each other of at least two of said configurations. In this case, the configuration of the spray unit can correspond to the configuration of the laundry treatment appliance and vice versa, even if this is not specified in detail below in individual cases.
The spray unit according to the invention for spraying a spray mist into a washing drum of a laundry treatment appliance has a retaining unit which can be connected to a support shield of the laundry treatment appliance and a nozzle unit which can be connected to the retaining unit without being released from damage, wherein the nozzle unit has a nozzle section with at least one nozzle opening, on the outer circumferential surface of which a driving contour is formed.
According to the invention, the nozzle unit can be actuated by means of a driving contour formed on the nozzle section in order to release a connection between the nozzle unit and the holding unit that can be released without damage. Since the nozzle section is arranged on the support shield toward the washing drum due to the nozzle opening arranged thereon and is thus directly accessible, the nozzle unit can be handled without having to remove components of the laundry treatment appliance, for example the front wall, beforehand. This merely entails swinging the door of the laundry treating appliance into an open position, through which the washing drum can be loaded with laundry. After releasing the connection between the nozzle unit and the holding unit, the nozzle unit can be released or removed from the holding unit, for example by manually or in a similar manner actuating the nozzle section in the direction of the washing drum, and then removed from the laundry treatment appliance, in order to be able to clean the nozzle unit, in particular the nozzle opening and/or the fluid channel of the nozzle unit, in a simple manner next to the laundry treatment appliance from dirt which deteriorates the spray characteristics of the nozzle unit. The connection of the nozzle unit to the holding unit is effected in the reverse order, wherein finally the connection of the nozzle unit to the holding unit is established again by actuating the nozzle section or the driving contour formed thereon. The effort for maintaining the laundry treatment appliance equipped with the spray unit according to the invention is therefore simplified and reduced.
The holding unit is fixed on the support shield. This can be achieved together with the nozzle unit arranged on the holding unit during assembly of the laundry treatment appliance, which simplifies assembly. The holding unit may be partially or preferably completely made of plastic. The holding unit can be manufactured using an additional manufacturing method or an injection molding method. The holding unit can be sealed against the support shield, for example by means of a sealing ring or the like, in order to prevent process air, which is conducted through the washing drum during the drying process, from being lost.
The nozzle openings can be arranged on the end sides or on the side faces of the nozzle sections of the nozzle unit. The nozzle opening is formed on the nozzle section in such a way that the spray mist emerging from the nozzle opening is also sprayed, if necessary, directly into the washing drum via the loading opening of the washing drum. The nozzle opening can be arranged, for example, such that the spray mist is sprayed into the washing drum from obliquely above in the direction of the axial center of the circumferential surface of the washing drum through the nozzle opening. The nozzle section may also have two or more nozzle openings. The nozzle section can be of cylindrical design, in particular a straight hollow cylinder.
The driving contour formed on the outer circumferential surface of the nozzle section can be formed for actuating the nozzle section and thus the nozzle unit by means of a tool. The driving contour can be configured, for example, as a hexagonal driving contour, which can be acted on by a nut wrench. Alternatively, the entrainment profile can be configured atypically or specifically and can be manipulated solely by means of a specific tool provided for use by a user of the laundry treatment appliance.
The nozzle unit may be partly or preferably entirely made of plastic. The holding unit can be manufactured using an additional manufacturing method or an injection molding method.
By means of the spray unit according to the invention, the spray mist can be sprayed into the washing drum of the laundry treatment appliance in order to level the laundry located in the washing drum during the rotation of the washing drum and possibly reduce the odor of the laundry. For this purpose, according to the invention, the liquid is not evaporated with the input of heat, but the liquid, which is approximately at ambient temperature, is conveyed under pressure and atomized by means of the nozzle opening. Thus, no energy is required for heating the liquid according to the invention, as a result of which the energy consumption of a correspondingly equipped laundry treatment appliance, in particular in the form of a heat pump dryer, is reduced.
The invention is advantageous compared to a spray unit which is of one-piece construction and is fastened to the support shield, for example by means of a seal, since in this spray unit it is not possible for the spray unit to be removed from the support shield for cleaning the spray unit without prior disassembly of the components of the laundry treatment appliance.
The spray unit according to the invention can be combined with other components in order to form a spray device which can be installed in a laundry treatment appliance. The spray device may, for example, have a water tank connected in communication with the spray unit, from which water can be output, which water is delivered to the nozzle opening. The water tank may be an additional component. Alternatively, the water tank can be a condensate water collecting container of the laundry treatment appliance, to which condensate water accumulated on a heat exchanger (evaporator) of the heat pump during the laundry treatment appliance, in particular during the drying process, is conveyed. The receiving volume of the water tank can be dimensioned such that the amount of water which can be stored in the water tank is only sufficient for carrying out a single process for smoothing the laundry present in the washing drum. A filter can also be arranged at the inlet opening of the water tank, by means of which filter out dirt particles from the water conveyed to the water tank. This is particularly advantageous when the water is condensed water, which typically contains fluff and the like. The filtering of the water supplied to the water tank extends the maintenance intervals for the maintenance of the spray device, in particular of the spray unit, in particular because fewer contaminants are supplied to the nozzle openings of the spray unit.
The spraying device can also have a water level sensor, for example a water level probe, by means of which the current water level in the water tank can be detected. The water level sensor can be connected to the electronics or program control of the laundry treatment appliance, which can be set up such that the process for smoothing the laundry contained in the washing drum is started and carried out only when the water level in the water tank exceeds a predefined lower limit value.
The spraying device can also have a pump which is connected to the water tank and the spraying unit via a fluid line, for example a hose, by means of which water is conveyed from the water tank to the spraying unit.
The laundry treatment appliance with the corresponding spray device can have a refill container, for example a bottle, as an additional device for filling the water tank with water. The user of the laundry treatment appliance can thus fill the water tank with the aid of the refill container. For this purpose, depending on the configuration of the laundry treatment appliance, it may be necessary to first remove a component of the laundry treatment appliance which is arranged directly above the water tank, for example a condensate water collecting container, so that the filling opening of the water tank can be reached. The outlet opening of the refill container is preferably matched to the inlet opening of the water tank in such a way that water can be introduced into the water tank without spilling.
A correspondingly designed injection device can thus be constructed in a modular manner and at least partially preassembled. This simplifies the installation of the spray device into the laundry treatment appliance. Furthermore, the spray device can be fitted more simply on the laundry treatment appliance. Furthermore, an easier replacement of individual components or of the entire injection device in the case of repair can be achieved. The spray unit according to the invention is already connected to the other components of the spray device at the side of the production line of the laundry treatment appliance, so that the completely preassembled spray device can be installed at the production line, which simplifies the production effort.
According to one advantageous embodiment, the nozzle unit is connected to the retaining unit in a form-fitting or force-fitting manner without being damaged in a loose manner. These two connection means can be connected and released again in a simple manner and a plurality of times. The force-fitting connection may be, for example, a screw connection.
According to a further advantageous embodiment, the nozzle unit can be connected to the holding unit by means of a bayonet connection without damage and without release. This is a special configuration of the form-fitting connection. At least one receiving slot of the bayonet connection may be arranged on the holding unit and a projection which can be inserted into or into the receiving slot may be arranged on the nozzle unit or vice versa.
According to a further advantageous embodiment, the nozzle unit has a connecting flange from which the nozzle section projects axially, and on the side of the connecting flange facing away from the nozzle section a first connecting piece is arranged, and the retaining unit has at least one second connecting piece which interacts with the first connecting piece. The connecting element makes possible a form-fitting or force-fitting connection between the nozzle unit and the retaining unit that can be released without damage. The first connection piece is arranged on the side of the connection flange facing away from the washing drum, whereby the nozzle unit can only be released or removed from the holding unit in the direction of the washing drum after the connection with the holding unit has been released. The diameter of the connecting flange is greater than the outer diameter of the nozzle section.
According to a further advantageous embodiment, the nozzle unit has a connecting pin which projects axially from the connecting flange on the side of the connecting flange facing away from the nozzle section and is inserted into a fluid supply channel of the holding unit, wherein the fluid channel extends through the connecting pin, the connecting flange and the nozzle section, the nozzle opening is connected in communication with the fluid channel, and the fluid channel terminates in the nozzle section. Preferably, the nozzle section of the connecting flange and the connecting pin are integrally connected to one another.
According to a further advantageous embodiment, at least one circumferential seal is arranged on the radial and/or axial outer side of the connecting pin. As a result, the connecting pin can be pressed into the fluid supply channel of the holding unit with elastic deformation of the seal, for example of a sealing ring, thereby sealing the nozzle unit relative to the holding unit. This prevents the liquid delivered to the nozzle opening from undesirably overflowing upstream of the nozzle opening, which may deteriorate the ejection characteristics of the ejection unit.
According to a further advantageous embodiment, the holding unit is of pot-shaped design and has a base with a fluid supply channel. The connecting flange can be supported axially on the bottom of the holding unit. The holding unit is open toward the washing drum. The shell of the holding unit, which is connected circumferentially to the bottom, can be beveled on its free end in order to provide more space for the spray mist exiting from the nozzle opening.
According to a further advantageous embodiment, at least one latching means is formed on the holding unit for establishing a latching connection between the holding unit and the support shield. The holding unit and thus the spray unit are thus fixed to the support shield in a simple manner and without the use of tools in the production line of the laundry treatment appliance, which simplifies the production.
The laundry treatment appliance according to the invention has at least one support shield, a washing drum and at least one spray unit arranged on the support shield for spraying a spray mist into the washing drum, wherein the spray unit is configured according to any one of the configurations described above or a combination of at least two of said configurations with one another.
The advantages mentioned above in connection with the spray unit apply correspondingly to the laundry treatment appliance. The support screen is in particular a front or front support screen, which is arranged on the side of the loading opening of the washing drum. The laundry treatment appliance can be, for example, a laundry dryer, a washer-dryer or a washing machine. The laundry treatment appliance can have a heat pump which is thermally coupled to the process air circulation system. Furthermore, the laundry dryer may have a condensate water collecting container. The laundry treatment appliance can have the aforementioned spray device, which can be controlled by electronic means in order to carry out a process of smoothing the laundry located in the washing drum.
