Description

The invention relates to an air treatment device for treating air according to the preamble of claim 1.Prior ArtFrom the prior art, for example, DE 10 2020 112 867 A1 discloses a compact air treatment device in which functions such as, for example, air moistening, cleaning, cooling, dehumidifying or the like are carried out.Object and Advantages of the InventionIn contrast, it is the object of the invention to propose an air treatment device for treating room air, which at least partially improves the disadvantages of the prior art.This object is achieved, starting from an air treatment apparatus of the type mentioned in the introduction, by the features of claim 1. By means of the measures mentioned in the dependent claims, advantageous embodiments and further developments of the invention are possible.The air treatment device comprises a housing, at least one treatment station, a flow path for letting the air flow through the at least one treatment station, a fan for pumping the air through the treatment station, and a control unit for controlling the fan, the ventilation flow generated by the fan and / or the treatment station, wherein the treatment station, the fan and the flow path are accommodated in the housing. The flow path has an air inlet through which air is introduced into the flow path from outside the housing, and an air outlet through which the optionally treated air of the air flow is conducted again out of the housing. For example, the treatment station is designed as a moistening station or as an air cleaning station. It is conceivable for the air cleaning station to have a filter.The air treatment apparatus is compactly accommodated in the housing, in contrast to air conditioning systems in which the functional units are distributed separately at different points in the space.Accordingly, the air treatment device according to the invention is characterized in that the treatment station comprises a tub which is mounted in the housing and can be removed from the housing. It is conceivable for the trough to at least partially surround the treatment station and for the trough to be removable from the housing together with the entire treatment station. A treatment station with a removable trough has the advantage, on the one hand, that the cleaning of the treatment station is simplified. Instead of the tub or the cleaning station having to be cleaned within the housing in a complicated manner and possibly only a moderate cleaning result can be achieved by a small amount of space and access to the treatment station restricted by the housing, the tub can be removed from the housing and can be cleaned thoroughly.On the other hand, a removable trough also has the advantage that the treatment station can be removed from the flow path, so that in the case that a plurality of treatment stations are present in the housing, the air can only be treated with selected functions and an undesired treatment station is easily removed.Ideally, the treatment station or at least one of the treatment stations is designed as a cleaning station with a filter for cleaning the air from dirt particles or the like and / or as a moistening station for moistening the air with water. Especially in winter months, the room air from heating is very dry, so that it is expedient here to moisten the air. With regard to allergic persons, it is also expedient to be able to clean the air in the room, for example from house dust. In spring and summer, when pollen from the preterm flowers is in the air, it is particularly advantageous to be able to free the air from allergenic particles.The trough is preferably designed for mounting a functional unit, in particular a filter and / or a rotary roller for cold evaporation and air moistening. In this way, the removal of an entire functional unit is facilitated for the user, whether for example for cleaning, repair, replacement or simple, because the function is not currently required or desired. With little outlay and no or only a few individual parts, the tray with the complete functional unit is removed from the housing. The general handling is accordingly simplified in this way.If the functional unit can be removed from the trough, the cleaning or maintenance of both parts can be carried out more easily and usually also more thoroughly. Accordingly, such a configuration is more hygienic for use.Advantageously, the tub can also be stored in the housing without a functional unit and / or the operation of the air treatment device can also be carried out without a functional unit with the tub as an empty stretcher. It is precisely when the corresponding function is not required or desired at present, it is practical if the operation of the air treatment device also functions without a functional unit in the tub. In order not to interrupt or divert the air flow, it may be expedient to store the trough empty in the housing. The air then flows further along the flow path and past or through an empty trough without being further treated here. Advantageously, in a further development, operation with the moistening station switched off is also possible, even if the tub with the functional unit remains in the housing. Thus, a convenient switching is possible and the user merely needs to empty the tub with the residual water.Ideally, a control unit for controlling the treatment of the space velocities is provided and is designed to be switchable in order to switch between cleaning by the cleaning station and / or air moistening by the moistening station and / or a joint operation of cleaning station and moistening station. The control unit can either have a sensor system in order to detect the need for the various operating modes and to switch them accordingly by itself or else can be changed over manually. It is thus possible to control which treatment functions are actively switched, such that no undesired function is active and energy and / or resources are unnecessarily consumed.Preferably, when the cleaning station and the moistening station are operated together, both stations, cleaning station and moistening station are connected in series. In this way, all air in the flow path can be both cleaned and humidified, so that the efficiency and the efficiency of the air treatment device are increased.In a preferred embodiment, a motor drive for driving the rotational movement of the rotary roller is provided, which can be switched on and off by the control unit during the changeover, wherein the motor drive is either arranged outside the moistening station and cannot be removed with the moistening station and / or the rotary roller, or is integrated in the moistening station and can be removed with it. The motor drive drives the rotary roller, partially protrudes into water in a water container, rotates driven by a motor drive and thus periodically partially dips into the water and is moved out of the water again. By means of cold evaporation, moisture is released into the air in contact between the air which passes along the flow path through the moistening station and the wetted surface of the roller. For example, the control unit can control that the rotary roller is rotated at a predetermined speed, depending on the desired degree of moistening.Preferably, the tub for filling and / or emptying, in particular for filling and / or emptying the water container, can be removed. Thus, emptying of old and / or no longer required water or filling with fresh water can be made simple.DESCRIPTION OF THE FIGURESExemplary embodiments of the invention are illustrated in the drawings and are explained in more detail below with the specification of further details and advantages. In detail, the following show: FIG. 1 is a schematic representation of an air treatment device according to the invention with a cleaning station and a moistening station in each case in a tub; and FIG. 2 : shows a schematic illustration of an air treatment device according to FIG. 1 without moistening station in the flow path.Fig. 1 schematically shows an air treatment apparatus 1 according to the invention. An air inlet 15 and an air outlet 16 are arranged on the housing 2 of the air treatment device 1. Between the air inlet 15 and the air outlet 16 a flow path 4 is present within the housing 2, through which air can be conducted. The air is pumped by a fan 5 from outside the air processing device 1 through the air inlet 15 into the flow path 4, along the flow path 4 and finally through the air outlet 16 back out of the housing 2. In principle, a fan can be used at any point in the flow path in order to ensure the air flow.Along the flow path 4, the air flows past or through different locations at different treatment stations 3 in order to be processed. For example, a cleaning station 8 and a moistening station 10 are shown as treatment stations, which are arranged in the flow path 4. The treatment stations 3 comprise a trough 7, which is mounted in the housing 2 and can be removed from the housing 2. A first treatment station 3 is designed in this embodiment as a cleaning station 8 with a filter 9, through which the air is conducted and thus cleaned, for example, from dirt particles.A further treatment station 3 is designed as a moistening station 10 and has a water container 14 in which water is stored, and a rotary roller 11, wherein the rotary roller 11, which partially protrudes into the water, rotates driven by a motor drive 13 and thus periodically dips partially into the water and is moved out of the water again. By means of cold evaporation, moisture is released to the air in contact between the air which passes the moistening station 10 along the flow path 4 and the wetted surface of the rotary roller 11.The troughs 7 can be removed from the air treatment device 1 together with the functional units 17 arranged in the respective troughs 7. Functional units 17 in the embodiment variant shown are the rotary roller 11, the water container 14, the filter 9 and the motor drive 13.FIG. 2 shows the air treatment device 1 according to FIG. 1, wherein the functional units 17 of the moistening station 10 with the tub 7 and / or from the tub 7 and correspondingly also from the housing 2 (dashed arrow) and thus are removed from the flow path 4. The air continues to be conducted along the flow path 4, but is not humidified due to the lack of functional units 17 of the humidification station 10. The trough 7 of the moistening station 10 thus functions as an empty section 12.List of reference characters1 Air treatment device 2 Housing 3 Treatment station 4 Flow path 5 Fan 6 Control unit 7 Trough 8 Cleaning station 9 Filter 10 Moistening station 11 Rotary roller 12 Empty section 13 Motorized drive 14 Water container 15 Air inlet 16 Air outlet 17 Functional unitReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
