Description

Laundry care device with a radial fan

The present invention relates to a laundry care device with a radial fan.

During a washing operation in a laundry care appliance, such as e.g. one

Washing machine, the laundry to be cared for is cleaned with washing liquor. In

Laundry care equipment may add a deodorizing module to the tub through a deodorizing module, such as a deodoriser. Ozone, water mist or perfume supplied to remove unpleasant smelling odors of the laundry in the washing drum or cover. After completion of the deodorizing treatment, the deodorizing substance is removed from the tub, which is advantageous to the user, especially when using potentially harmful ozone.

US 2009/0074596 A1 describes a pump for mixing ozone and water with an engine in order to effectively dissolve ozone in water and to obtain an ozone-water mixture.

It is the object underlying the invention to provide a laundry care device with a deodorizing module in which the deodorizing substance is effectively removed after completion of the deodorizing process.

This object is achieved by articles having the features according to the independent claims. Advantageous embodiments of the invention are the subject of the figures, the description and the dependent claims. According to one aspect of the invention, the object is achieved by a laundry care device with a tub, and a deodorizing module for dispensing

Desodorierungsubststanz solved to the tub, wherein the deodorizing module is connected to the tub and a radial fan for ventilating the

Wherein the centrifugal fan is drivable in a first direction of rotation and in a second direction of rotation, wherein the deodorizing module is designed to deliver deodorising substance to the tub in a first period of time, the radial fan being drivable in the first direction of rotation in the first period, to disperse the deodorizing substance in the tub, and wherein the

Radial fan is drivable in a second period subsequent to the first period in the second direction of rotation to remove the deodorizing substance in the second period from the tub.

As a result, the technical advantage is achieved that by the two different directions of rotation of the centrifugal fan two different intense air currents in the

Lye container can be generated, whereby the required intensity of the air flow can be advantageously adjusted depending on the process step of the deodorizing process. The laundry care appliance comprises a deodorizing module for dispensing

Deodorizing substance to the tub. Deodorising substances include substances which are added to the laundry in order for the user of the

Laundry care device to eliminate unpleasant odors. Deodorizing substances may either comprise odor-active substances which mask unpleasant odors or may comprise substances which eliminate unpleasant odors, either by absorption or adsorption of the unpleasant odors or by chemical reaction with the unpleasant odors. For example, a deodorizing module may be an ozone generating element for generating ozone, a mist generating device for generating water mist or a

Scent delivery element for dispensing fragrance include. The deodorization may be performed as a separate laundry care process or in combination with a conventional laundry care program.

When using one or more deodorizing substances, it is intended to ensure that the deodorising substance after the

Deodorizing process is removed from the tub again. This prevents the user of the laundry care device when removing laundry from the washing drum with possibly still present in the tub

Deodorizing substance comes into contact. This is particularly important when using ozone, as ozone in high concentrations may be harmful to the user's health. For this purpose, the deodorizing module connected to the suds container comprises a radial fan which is designed to generate an air flow which can be supplied to the suds container in order to aerate the suds container. In the first period, deodorizing substance is provided by the deodorizing module and delivered to the tub to remove unpleasant odors present in the laundry. Here it is crucial that the radial fan is driven in the first direction of rotation, and generates a small air flow in the tub, which is sufficient to distribute the deodorizing substance in the tub. After the removal of the unpleasant

Odorants is the existing in the tub deodoriser in a subsequent to the first period second period of the

Lye container removed. Here it is crucial that the radial fan is driven in the second direction of rotation and generates an intense air flow in the tub, which is sufficient to the deodoriser again from the

The radial fan is configured to draw air along a first axis and exhaust the aspirated air along a second axis, the second axis and the first axis forming a 90 ° angle, which does not change the direction when the direction of rotation of the radial fan changes the air flow is changed, but only the intensity of the air flow. Since the second direction of rotation of the radial fan is the preferred direction of rotation of the radial fan due to the geometric design of the radial fan, the radial fan generates a more intense air flow in the second direction of rotation than in the first direction of rotation. Thus, it is possible different intensive air flows only by changing the

To generate the direction of rotation of the radial fan. The different intensity air streams are generated by the geometric design of the radial fan and are obtained in particular at an identical supply voltage of the radial fan in the first direction of rotation and the second direction of rotation. This results in a precise adjustability of the desired intensity of the air streams in the tub, especially at low flow rates.

This achieves the technical advantage that at the same

Supply voltage of the fan drive in the first or second direction of rotation of the radial fan, the difference in the intensity of the air currents generated is ensured exclusively by the geometric design of the radial fan. Due to the geometric design of the radial fan, the second volume flow in the second direction of rotation of the radial fan is greater than the first volume flow in the first direction of rotation at the same supply voltage. As a result, only by changing the direction of rotation of the radial fan an effective adaptation of the

Further embodiments will be explained with reference to the accompanying drawings. FIG. 1 shows a schematic front view of a laundry care appliance; FIG.

Fig. 2 is a schematic interior view of a laundry care device with a

Desodorierungsmodul; and 3 shows a sequence of a method for the care of laundry

Laundry care device.

Fig. 1 shows a schematic front view of a general laundry care appliance 100, such as e.g. a washing machine. The laundry care device 100 comprises an induction bowl 101, into which detergent can be introduced. The laundry care appliance 100 comprises a door 103 for loading the laundry care appliance 100 with laundry.

Fig. 2 shows a schematic interior view of a laundry care device with a

Desodorierungsmodul. Through the door 103 of the laundry care device 100, the user can load the washing drum 105 of the laundry care device 100 with laundry. The

Washing drum 105 is arranged in the tub 107 of the laundry care device 100. In the laundry care device 100 is a deodorizing module 109th

arranged, which with the tub 107 by a first and second

Connecting line 1 1 1, 1 13 is connected. The deodorizing module 109 gives

Deodorizing substance through the first connection line 1 1 1 to the conduit container 107, wherein the deodorizing substance can be removed through the second connection line 1 13 Again from the tub 107. Deodorising substances include substances which are added to the laundry to provide for the user of the laundry

Laundry Care Device 100 to remove or mask unpleasant odors. A deodorizing module 109 may include an ozone generating element for generating ozone, a mist generating device for generating water mist or a

Scent delivery element for dispensing fragrances. In order to ensure effective ventilation of the tub 107, the laundry care device 100 has a radial fan 1 15, which is driven by a fan drive 1 17 via a fan shaft 1 19. The fan drive 1 17 is arranged in particular outside the deodorizing module 109 in order to prevent the

Deodorizing substance to be protected in the deodorizing module 109. The radial fan 1 15 is disposed within the deodorizing module 109. In a shaft bushing, an effective sealing of the deodorizing module 109 is advantageous, but without increasing the frictional resistance by sliding sealing systems. For this purpose, the passage of the fan shaft 1 19 through the module housing of Desodonerungsmoduls 109 laid. In radial fans this usually occurs

Negative pressure on. The deodorizing module 109 is intentionally leaky at the opening so as to exclude the discharge of deodorizing substance from the deodorizing module 109 by means of a continuous flow of air generated by the negative pressure from outside into the interior of the deodorizing module 109. A particular advantage is that in the implementation of the fan shaft 1 19 reduced by the module housing

Friction losses occur and also allow manufacturing tolerances of the module housing cost-effective production.

A deodorization process can be conducted in different modes. In a deodorizing module 109 with an ozone generating element and with a

In particular, the following modes are to be distinguished.

During the ozone generation and the misting of the laundry, the smallest possible volume flows of air through the radial fan 1 15 must be provided in order to prevent the

Distribute deodorants in the tub 107, and to maximize the effect of the substances. During the ozone depletion, however, should be a maximum

Volumetric flow are available so that the deodorizing substance, in particular

Ozone, is effectively removed from the tub 107.

In general, in a centrifugal fan 1 15 by a change in the rotational speed of the flow rate of the moving air through the radial fan 1 15 are changed.

In particular, in DC-operated small fans, the speed adjustment takes place by a change in voltage, with a lower voltage corresponding to a lower speed and a lower volume flow, and wherein a higher voltage corresponds to a higher speed and a higher volume flow. However, a control of the volume flow by an exclusive reduction in the rotational speed of a centrifugal fan 1 15 are limited, since due to

System friction certain voltage limits or speed limits can not be undershot. The demand for variable volume flows can be fulfilled particularly advantageously with a radial fan. The radial fan 1 15 can be driven in a first direction of rotation 121 and in a different second direction of rotation 123, wherein the radial fan 1 15 at the different directions of rotation 121, 123, the conveyed air always moving in the same direction. In a drive of the centrifugal fan 1 15 in the first direction of rotation 121, which is opposite to the second direction of rotation 123, generates the radial fan 1 15 despite the same supply voltage a much lower flow than in the second direction of rotation 123. The inversion of the direction of rotation 121, 123 thus corresponds to one Switching the fan characteristic curve, whereby at a

Comparable speed level of the fan drive 1 17 can be switched between high and low air flow. Since both in the first direction of rotation 121 and the second direction of rotation 123 of the centrifugal fan 1 15 in addition the speed can be adjusted, there is a precise adjustability of the desired volume flow, especially at low air flow.

The removal of ozone is a safety-relevant function in the laundry care device 100. The door 103 of the laundry care device 100 may only be unlocked when a safe concentration is reached. Consequently, the door lock of the

Laundry care device 100 are deactivated only when the amount of ozone in the tub 107 of the laundry care device 100 has fallen below a certain ozone value. Here, a model of ozone depletion is used, whereby a period is calculated from the model, during which the radial fan 1 15 must be driven at a certain speed until the ozone reaches a certain,

safety-related ozone value has fallen below. In this case, it is assumed that the measured speed of the fan drive 1 17 and the speed of the centrifugal fan 1 15 corresponds. The latter presupposes that the radial fan 1 15 functions as intended, i. firmly seated on the fan shaft 1 19 and is not defective.

Here, a method is used in which the laundry care apparatus 100 includes a controller and a power detection element for detecting a power value of the centrifugal fan 15, and the following steps are performed. In a first step, the radial fan 1 15 is operated with a defined supply voltage in the first direction of rotation 121, wherein the radial fan 1 15 generates a lower volume flow in the first direction of rotation 121 compared to the second direction of rotation 123. The power detection element detects at least one power value of the

Fan drive 1 17, such as speed of the fan drive 1 17, the voltage applied to the fan drive 1 17 electric current and / or the air pressure generated by the radial fan 1 15. The speed of the fan drive 1 17 can when using a DC-based fan drive 1 17 can be determined with brushes on the current ripple.

In a second step, the radial fan 1 15 is operated with the voltage defined in the first step in the second direction of rotation 123, wherein in the second direction of rotation 123 in comparison to the first direction of rotation 121 of the centrifugal fan 1 15 a larger

Volume flow is generated. The power detection element in turn detects at least one power value of the fan drive 1 17.

In a third step, the power values detected by the power detecting element in the first and second rotating directions 121, 123 are compared with each other by the controller. Due to the different air guide properties of the radial fan 1 15 in the first direction of rotation 121 relative to the second direction of rotation 123 different power values must necessarily be detected in a correct operation of the centrifugal fan 1 15. If a comparison of the detected power values reveals that the power difference is less than a threshold value, in particular 20%, then a malfunction of the radial fan 1 is 15

go out. If the radial fan 1 15 functions correctly, the recorded power values must be more than a threshold, in particular 20%,

differ.

In a fourth step, a stepwise increase in the voltage of the

Fan drive 1 17 set the target speed of the radial fan 1 15. In this case, at least one power value of the

Fan drive 1 17, such. Speed, supply current or air pressure detected both in the first direction of rotation 121 and in the second direction of rotation 123 of the radial fan 1 15. The smaller the voltage levels fail, the more accurately the entire characteristic range of the radial fan 15 can be checked.

In a fifth step, the controller compares the first and second power values detected at the various times with corresponding ones

Reference power values and determines the deviation from the reference power values. In a sixth step, the control measures the target speed when the target speed is reached abovementioned measured variables continuously and compares the measured variables with the permissible reference power values.

In a seventh step, the controller assumes, if the by the

Performance sensing element detected power values and the resulting

Comparative values outside the permissible value range are such that the function of the radial fan 1 15 is not guaranteed. In this case, the controller will be the

Do not disable the door lock until a time interval has elapsed to

ensure that the amount of ozone in the tub 107 of the

Laundry care device 100 has fallen to a safe level. In addition, the laundry-care device 100 may additionally comprise a signal-generating device which is designed to display a warning signal to the user.

A corresponding laundry care device 100 has the following advantages. The modular structure of the laundry care device 100 can be integrated into each laundry care device 100. The sensitive components of the radial fan 1 15, such.

Fan drive 1 17, are not exposed to the aggressive ozone, causing the

Lifespan increased. In addition, the radial fan allows for a more precise adjustment of the volumetric flow control for the various modes of operation, e.g. Ozone generation, nebulization on the one hand and ozone depletion on the other hand be ensured. In addition, two different volumetric flow ranges can even without variable

Voltage supply can be enabled, but only by inverting the direction of rotation of the radial fans 1 15. An increase in the resolution of the adjustable volume flow is achieved by a speed control, which can generate very low volume flows.

FIG. 3 shows a schematic illustration of a method 200 for maintaining laundry in a laundry care device 100 according to FIGS. 1 and 2, wherein the method 200 comprises the following method steps. Distribute 201 of the

Deodorizing substance in the tub 107 in a first period, wherein the radial fan 1 15 in the first period in the first direction of rotation 121 is drivable. The removal 203 of the deodorizing substance from the tub 107 in a subsequent to the first period second period, wherein the radial fan 1 15 is drivable in the second period in the second direction of rotation 123. The method 200 may further include, during the distribution 201 of the deodorizing substance in the tub 107 or the removal 203 of the deodorizing substance from the tub 107, changing a rotational speed of the centrifugal fan 15 in the first or second rotating directions 121, 123.
