TECHNICAL FIELD
[0001] The present application relates to the field of household appliances, and in particular to a sparger for a laundry care appliance and a laundry care appliance. BACKGROUND
[0002] In laundry care appliances, it is often necessary to mix a liquid, such as a mixture of detergent and water, with laundry.
[0003] Taking a washing machine as an example, the mixture of detergent and water needs to be mixed with laundry to pre-treat the laundry and thus achieve a good washing result. To this end, a water inlet device can be used to introduce the liquid into a laundry drum so as to mix with the laundry in the laundry drum. However, the existing water inlet device is difficult to ensure that the laundry is uniformly mixed with the mixture. A large amount of the mixture flows into the space between the laundry drum and the outer drum of the laundry care appliance without contacting the laundry after entering the laundry drum. This results in a large amount of the mixture not being effectively used for the pre-treatment of the laundry, and causes the laundry to be mixed with the detergent unevenly. This is not conducive to the washing result.
[0004] In addition, at least a part of the mixture is directly delivered to the space between the outer drum and the laundry drum of the laundry care appliance. This part of the mixture with detergent does not mix with the laundry. This is also not conducive to achieving a good washing result. SUMMARY
[0005] It is a basic object of embodiments of the present application to provide a sparger for a laundry care appliance and a corresponding laundry care appliance. The open door device and the laundry care appliance according to the present application are in particular capable of overcoming at least one of the above-described deficiencies of the prior art.
[0006] According to a first aspect of the present application, embodiments of the present application provide a sparger for a laundry care appliance, the sparger being configured to sparge a liquid to laundry in a laundry drum of the laundry care appliance. The sparger comprises a tubular wall surrounding a longitudinal axis of the sparger and having an inlet, and a nozzle at an end of the tubular wall distal to the inlet, the nozzle having a sparging opening open transversely to the longitudinal axis, thereby defining a main sparging direction transversely to the longitudinal axis.
[0007] Thus, the injector is able to use the nozzle to spray a jet of liquid directly onto laundry in the laundry drum. In conventional laundry care appliances, liquid is not sprayed directly onto the laundry, but is rather delivered into the laundry drum, for example by means of a water inlet, or into an outer drum surrounding the laundry drum. The configuration of existing water inlets is not designed to form a jet that is sprayed directly onto the laundry, so that liquid flowing from the water inlet only comes into contact with the laundry adjacent to the water inlet or flows into the space between the laundry drum and the outer drum without coming into contact with the laundry. This results in the laundry not being sufficiently and uniformly contacted by the liquid. In contrast, the injector of the present application is able to form a jet of liquid with a long spray distance and a large spray range, which facilitates uniform mixing of the liquid with the laundry, thereby improving the washing result and avoiding waste.
[0008] According to an optional embodiment of the present application, the nozzle can comprise a top wall and a bottom wall oriented transversely to the longitudinal axis and opposite to each other, and a first side wall and a second side wall connecting the top wall and the bottom wall, the top wall, the bottom wall, the first side wall and the second side wall enclosing the spray opening. In a cross section perpendicular to the longitudinal axis, a side wall included angle between the first side wall and the second side wall can be formed, which is not 0, so that a distance between the first side wall and the second side wall increases along the main spray direction. Thus, the nozzle can spray a fan-shaped jet. This facilitates achieving a large spray range.
[0009] According to an optional embodiment of the present application, the side wall included angle is an acute angle. This facilitates achieving a suitable spray range and spray distance.
[0010] Optionally, the side wall included angle is between 45° and 60°. The side wall included angle is for example 50°. Such a side wall included angle is particularly advantageous for achieving a suitable spray range and spray distance, taking into account the flow rate of liquid and the size of the laundry drum in conventional laundry care appliances.
[0011] According to an optional embodiment of the present application, a cross section of the spray opening perpendicular to the main spray direction can have a substantially rectangular shape, a length direction of the cross section being perpendicular to the main spray direction and substantially perpendicular to the longitudinal axis, a width direction of the cross section being perpendicular to the length direction and the main spray direction.
[0012] In the present text, “substantially perpendicular” specifies in particular an orientation of a direction with respect to a reference direction, wherein, in particular, viewed in a plane, the direction and the reference direction enclose an angle of 90°, and the angle has a maximum deviation of in particular less than 10°, advantageously less than 5°, particularly advantageously less than 2°.
[0013] Optionally, an aspect ratio of the cross section of the spray opening perpendicular to the main spray direction is greater than 4. Such a flat spray opening is able to make the sprayed jet have a long spray distance, thereby ensuring that the liquid can be directly sprayed onto the laundry.
[0014] Optionally, the area of the cross-section of the injection opening perpendicular to the main injection direction can be less than 50 mm 2 A smaller cross-section helps to achieve a longer injection distance.
[0015] Optionally, the dimension of the cross-section of the injection opening perpendicular to the main injection direction in the width direction can be less than 3 mm. This means that the injection opening has a rather flat shape.
[0016] Optionally, the length direction of the injection opening is inclined by an angle between 1° and 10° with respect to a plane perpendicular to the longitudinal axis. This helps to enable laundry in the laundry drum to be directly injected with liquid over a larger range.
[0017] According to one optional embodiment of the present application, the dimension of the cross-section of the injection opening perpendicular to the main injection direction in the width direction can increase along the main injection direction. Optionally, the dimension of the cross-section of the injection opening perpendicular to the main injection direction in the width direction can increase by at least a factor of two along the main injection direction. This particularly helps to enable the jet to spread in the width direction in order to achieve a uniform injection.
[0018] According to one optional embodiment of the present application, the dimension of the cross-section of the injection opening perpendicular to the main injection direction in the length direction can increase along the main injection direction. This helps to achieve a larger injection range.
[0019] Optionally, the dimension of the cross-section of the injection opening perpendicular to the main injection direction in the length direction can increase by at least a factor of one and / or at most a factor of two along the main injection direction. This particularly helps to achieve a suitable injection range and injection distance.
[0020] According to one optional embodiment of the present application, the tube wall can be provided with at least one auxiliary opening, which penetrates the tube wall in a direction transverse to the longitudinal axis. By means of the auxiliary opening, the injector can flush a door or a door seal of the laundry care appliance with liquid in order to carry away detergent at the door or the door seal.
[0021] For example, the auxiliary opening is closer to the inlet than the nozzle.
[0022] In particular, at least one of the auxiliary openings can be arranged on a side of the tube wall opposite to the nozzle and open in a direction away from the main injection direction. Thereby, it can be ensured that liquid flowing out of the auxiliary opening can flush a door or a door seal of the laundry care appliance.
[0023] According to an optional embodiment of the present application, the auxiliary openings can be formed as strip-shaped holes and are arranged obliquely with respect to the longitudinal axis. Such an oblique arrangement of the auxiliary openings can both prevent liquid flowing out of the auxiliary openings from leaving a residue along the tube wall and cause the liquid flowing out of the auxiliary openings to have a relatively small flow rate and / or a relatively small ejection distance. The auxiliary openings can in particular be arranged obliquely by 30° to 60° with respect to the longitudinal axis.
[0024] According to an optional embodiment of the present application, the at least one auxiliary opening can comprise a plurality of auxiliary openings arranged around the longitudinal axis. The auxiliary openings can cooperate with the ejection opening to ensure that the laundry in the laundry drum can be uniformly directly sprayed with liquid.
[0025] The total area of the at least one auxiliary opening through the tube wall can be larger than the area of the ejection opening through the tube wall. This can help to ensure that the liquid sprayed by the auxiliary openings has a desired ejection distance.
[0026] In particular, the sum of the areas of the at least one auxiliary opening through the tube wall of the auxiliary openings located at the same longitudinal position in the direction of the longitudinal axis can be larger than the area of the ejection opening through the tube wall. This can help to further ensure that the liquid sprayed by the auxiliary openings has a desired ejection distance.
[0027] According to an optional embodiment of the present application, the ejector is provided with a mounting ring protruding outward from the tube wall, the mounting ring extending around the tube wall in a ring plane, the ring plane being oblique with respect to a plane perpendicular to the longitudinal axis. This can help to achieve a desired ejection distance and ejection range. The angle of the ring plane with respect to a plane perpendicular to the longitudinal axis can in particular be between 2° and 5°, as seen in the main ejection direction.
[0028] According to an optional embodiment of the present application, the ejector is provided with a tab arranged in a non-rotationally symmetrical manner with respect to the longitudinal axis, the tab protruding outward with respect to the tube wall and extending along the longitudinal axis. The tab can be used to ensure that the ejector is correctly mounted in place and to prevent the ejector from undesired rotation.
[0029] At least in the end of the tab closer to the inlet, the dimension of the tab protruding outward with respect to the tube wall can decrease in the direction along the longitudinal axis towards the inlet. This can make the mounting of the ejector more convenient.
[0030] The tab can in particular be closer to the inlet than the mounting ring.
[0031] According to a second aspect of the present application, embodiments of the present application provide a laundry care appliance having a laundry drum for accommodating laundry and an ejector according to the present application arranged adapted to spray liquid to the laundry in the laundry drum.
[0032] According to an optional embodiment of the present application, the laundry care appliance further has a loading opening via which laundry can be put into the laundry drum, a door arranged adapted to close the loading opening, and a door seal arranged adapted to form a sealing contact with the door around the loading opening, the injector being mounted to the door seal. The injector can be formed as a separate component relative to the door seal. The injector can be plugged to the door seal, for example.
[0033] According to an optional embodiment of the present application, the loading opening is arranged to open transversely to a height direction of the laundry care appliance, the door seal is ring-shaped, and the injector is arranged such that its longitudinal axis is inclined relative to a radial direction of the door seal such that the nozzle of the injector is offset upwards in the height direction of the laundry care appliance. This helps to achieve a desired spray range such that the spray range covers the laundry in the laundry drum comprehensively.
[0034] According to an optional embodiment of the present application, the laundry care appliance further has a detergent box for receiving a detergent, the injector being connected to the detergent box by a duct such that a mixture of detergent and water flowing out of the detergent box enters the laundry drum via the injector. Thereby, all of the mixture is directly sprayed by the injector towards the laundry. The mixture can be applied sufficiently to pre-treat the laundry such that waste is prevented.
[0035] According to an optional embodiment of the present application, the laundry care appliance is a washing machine. BRIEF DESCRIPTION OF DRAWINGS

[0063] In order to make the technical problems to be solved by the present application, the technical solutions and the beneficial technical effects more clearly understood, the present application will be further described in detail below in conjunction with the drawings and multiple example embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the protection scope of the present application.
[0064] First, in order to facilitate understanding, back to the description in the background section, the laundry care appliance in the prior art liquid is wasted, clothes and liquid mixing is uneven and / or washing effect needs to be improved, etc.
[0065] To at least one of the above technical problems or other possible technical problems, one example embodiment of the present application provides a sparger for a laundry care appliance, the sparger being configured to sparge a laundry care appliance with liquid towards laundry within a laundry drum of the laundry care appliance. The sparger comprises a tubular wall surrounding a longitudinal axis of the sparger and having an inlet, and a nozzle at an end of the tubular wall distal to the inlet, the nozzle having a sparge opening open transverse to the longitudinal axis, thereby defining a main sparge direction transverse to the longitudinal axis.
[0066] For better understanding of the present application, example embodiments of the present application will be described below with reference to the accompanying drawings. It should be noted that the directional terms used in the description refer to the normal use state of the laundry care appliance for the sake of convenience of description, and should not be construed as absolute limitations of the corresponding features.
[0067] Figure 1 A perspective view of a laundry care appliance according to one example embodiment of the present application is schematically shown, wherein parts of the laundry care appliance are not shown in order to reveal its internal structure. Figure 2 A sparger 1 for a laundry care appliance according to one example embodiment of the present application is schematically shown.
[0068] In this embodiment, the laundry care appliance is a washing machine. However, it should be understood that the present application is also applicable to other appliances for care operations such as washing, drying and / or deodorizing laundry 20.
[0069] From Figure 1 and Figure 2 It can be seen that the laundry care appliance has a laundry drum 2 for accommodating laundry 20 and a sparger 1 arranged so as to sparge laundry 20 within laundry drum 2 with liquid. Sparger 1 comprises a tubular wall 11 surrounding a longitudinal axis L of sparger 1 and having an inlet 111, and a nozzle 12 at an end of tubular wall 11 distal to inlet 111. Nozzle 12 has a sparge opening 121 open transverse to longitudinal axis L, thereby defining a main sparge direction D transverse to longitudinal axis L S .
[0070] Thus, the injector 1 is able to spray the jet of liquid directly onto the laundry 20 in the laundry drum 2 by means of the nozzle 12. In conventional laundry care appliances, the liquid is not sprayed directly onto the laundry 20, but is delivered into the laundry drum 2 or into an outer drum surrounding the laundry drum, for example by means of a water inlet. The configuration of the existing water inlets is not designed for forming a jet that is sprayed directly onto the laundry 20, so that the liquid flowing from the water inlet only comes into contact with the laundry 20 adjacent to the water inlet or flows into the space between the laundry drum 2 and the outer drum without coming into contact with the laundry 20. This results in the laundry 20 not being sufficiently and uniformly contacted with the liquid. In contrast, the injector 1 of the present application is able to form a liquid jet having a long spray distance and a large spray range, which helps to uniformly mix the liquid with the laundry 20, thereby improving the washing effect and avoiding waste.
[0071] Here, the "main spray direction" means the main flow direction of the liquid jet sprayed by the nozzle 12. In the embodiment shown in Figure 1 and Figure 2 In the embodiment shown, the spray opening 121 opens in a direction perpendicular to the longitudinal axis L. The main spray direction D S perpendicular to the longitudinal axis L.
[0072] As shown in Figure 1 The laundry care appliance also has a loading opening 3 via which the laundry 20 can be put into the laundry drum 2, a door 4 arranged so as to close the loading opening 3, and a door seal 5 arranged around the loading opening 3 so as to form a sealing contact with the door 4. The injector 1 can be mounted to the door seal 5. The injector 1 is formed as a separate component relative to the door seal 5. The injector 1 can be plugged, for example, to the door seal 5.
[0073] The loading opening 3 can be arranged to open substantially perpendicularly to the height direction of the laundry care appliance, for example can open forwards. The injector 1 can extend, for example, through the door seal 5 into the loading opening 3.
[0074] Figure 1 It is also shown that the laundry care appliance has a detergent box 6 for receiving a detergent. The injector 1 can be connected to the detergent box 6 so as to receive a mixture of the detergent and water. Then, the injector 1 can spray the mixture of the detergent and water directly onto the laundry 20, in order to pre-treat the laundry 20. Thus, the laundry 20 can be uniformly mixed with the detergent, thereby improving the washing effect.
[0075] The injector 1 according to the exemplary embodiments of the present application is further explained below with reference to Figure 3 , Figure 4 and Figure 5 Figure 3 and Figure 4 schematically show the injector 1 passing through Figure 2 cross-sectional view along the section lines A-A and B-B in Figure 5 schematically shows the injector 1 in Figure 2 a partial enlarged view of the encircled portion in
[0076] It can be seen that the nozzle 12 can comprise a top wall 122 and a bottom wall 123 which are oriented transversely to the longitudinal axis L and opposite to each other, and a first side wall 124 and a second side wall 125 which connect the top wall 122 and the bottom wall 123. The top wall 122, the bottom wall 123, the first side wall 124 and the second side wall 125 enclose the injection opening 121. In a cross-section perpendicular to the longitudinal axis L, a side wall included angle a between the first side wall 124 and the second side wall 125 is formed which is not 0, so that the distance between the first side wall 124 and the second side wall 125 increases along the main injection direction D S . Thus, the nozzle 12 can inject a fan-shaped jet. This helps to achieve a larger injection range. In case the nozzle 12 injects a fan-shaped jet, the main injection direction D S is the direction along the center line of the fan.
[0077] The side wall included angle a is in particular an acute angle. This helps to make the jet injected by the nozzle 12 have a suitable injection range and injection distance. A too large side wall included angle a can result in that the liquid is difficult to be directly injected onto the laundry 20 located at the rear end of the laundry drum 2. The side wall included angle a being acute is in particular helpful to achieve a suitable injection range and injection distance. Optionally, the side wall included angle a is for example between 45° and 60°. The side wall included angle a is for example 50°. Such a side wall included angle a is in particular advantageous to achieve a suitable injection range and injection distance, taking into account the flow rate of the liquid and the size of the laundry drum in a conventional laundry care appliance.
[0078] A cross-section of the injection opening 121 perpendicular to the main injection direction D S may have a generally rectangular shape. See Figure 5 , the length direction D L of the cross-section is perpendicular to the main injection direction D S and is generally perpendicular to the longitudinal axis L, and the width direction D W of the cross-section is perpendicular to the length direction D L and the main injection direction D S .
[0079] According to exemplary embodiments of the present application, the aspect ratio of the cross-section of the injection opening 121 perpendicular to the main injection direction D S is greater than 4. Such a flat injection opening 121 is able to make the injected jet have a longer injection distance, so as to ensure that the liquid can be directly injected onto the laundry 20.
[0080] A cross-section of the injection opening 121 perpendicular to the main injection direction D Sof the cross section of the injection opening 121 in the width direction D W The dimension, for example, can be less than 3 mm. This means that the injection opening 121 has a rather flat shape.
[0081] The area of the cross section of the injection opening 121 perpendicular to the main injection direction D S is less than 50 mm 2 A smaller cross section helps to achieve a longer injection distance. In conventional laundry care appliances, liquid is not directly injected onto the laundry 20, but can be introduced into the laundry drum 2 by means of a larger water inlet. In this case, the liquid can come into contact with the laundry 20 in a small area near the water inlet, but it is difficult to reach more of the laundry 20.
[0082] The length direction D L of the injection opening 121 is not particularly perpendicular to a plane perpendicular to the longitudinal axis L. See Figure 5 The length direction D L of the injection opening 121 can form an angle β with respect to a plane perpendicular to the longitudinal axis L. β can be between 1° and 10°. This helps to enable the laundry 20 in the laundry drum 2 to be directly sprayed by the liquid sprayed by the injection opening 121 over a larger area.
[0083] In Figure 5 the cross sections of the injection opening 121 at the section lines C-C and D-D in Figure 4 are schematically shown in dashed rectangles R C and R D . It can be seen that the cross section of the injection opening 121 perpendicular to the main injection direction D S increases in the main injection direction D W in the width direction D S . This helps to cause the sprayed jet to spread in the width direction D W so that the liquid is sprayed evenly onto the laundry 20.
[0084] Alternatively or additionally, the cross section of the injection opening 121 perpendicular to the main injection direction D S increases in the main injection direction D L in the length direction D S . This helps to achieve a larger spraying range.
[0085] Optionally, the cross section of the injection opening 121 perpendicular to the main injection direction D S increases in the main injection direction D W in the width direction D S by at least a factor of two. This particularly helps to cause the sprayed jet to spread in the width direction D W to achieve an even spray.
[0086] The injection opening 121 is perpendicular to the main injection direction D. S The cross section in the length direction D L The dimensions on it, especially along the main injection direction D, can be adjusted. S Increase by at least double. This is particularly helpful in ensuring that the ejected jet is directed along the length direction D. L It diffuses upwards to achieve a larger spray range.
[0087] Optionally, the injection opening 121 is perpendicular to the main injection direction D. S The cross section in the length direction D L The dimensions on it, especially along the main injection direction D, can be adjusted. S Increase it by up to two times. This helps to achieve the appropriate spray range and spray distance.
[0088] Figure 2 and Figure 3 It is also shown that the pipe wall 11 may be provided with at least one auxiliary opening 112, which penetrates the pipe wall 11 in a direction transverse to the longitudinal axis L.
[0089] With the aid of auxiliary opening 112, the sprayer 1 can use liquid to flush the door 4 or door seal 5 of the garment care appliance, thereby removing detergent from the door 4 or door seal 5. Compared to spray opening 121, the liquid sprayed from auxiliary opening 112 can land closer to the sprayer 1. Auxiliary opening 112 and spray opening 121 can complement each other to achieve a spray range for covering all the clothes 20 inside the garment drum 2.
[0090] The auxiliary opening 112 can be closer to the inlet 111 than the nozzle 12. Therefore, the auxiliary opening 112 is located upstream of the nozzle 12.
[0091] The auxiliary opening 112 can be particularly formed as a strip-shaped hole and arranged obliquely relative to the longitudinal axis L. For example... Figure 2 and Figure 3 As shown, the auxiliary opening 112 is neither parallel to nor perpendicular to the longitudinal axis L. The auxiliary opening 112 forms an angle γ with the longitudinal axis L. This inclined arrangement of the auxiliary opening 112 prevents the liquid flowing from the auxiliary opening 112 from remaining along the pipe wall 11, while also ensuring a relatively small flow rate and / or a relatively small spray distance. The angle γ is particularly suitable for applications between 30° and 60°.
[0092] At least one of the auxiliary openings 112 may be provided on the side of the pipe wall 11 opposite to the nozzle 12, and in a direction away from the main injection direction D. SThe auxiliary opening 112 and the spray opening 121 are open in the direction of rotation. This helps to give the auxiliary opening 112 and the spray opening 121 complementary spray ranges. This also ensures that the liquid flowing out of the auxiliary opening 112 can rinse the door 4 or door seal 5 of the laundry care appliance.
[0093] In an exemplary embodiment according to this application, the at least one auxiliary opening 112 is provided only on the side of the pipe wall 11 opposite to the nozzle 12, and is oriented away from the main injection direction D. S The direction is open.
[0094] exist Figure 2 and Figure 3 In the illustrated embodiment, the at least one auxiliary opening 112 includes a plurality of auxiliary openings 112 arranged around the longitudinal axis L. The auxiliary openings 112 can cooperate with the spray openings 121 to ensure that the clothes 20 in the clothes drum 2 can be uniformly sprayed directly by the liquid.
[0095] Optionally, the total area of the at least one auxiliary opening 112 penetrating the pipe wall 11 is greater than the area of the injection opening 121 penetrating the pipe wall 11. This helps ensure that the liquid ejected from the auxiliary opening 112 has the desired spray distance. Specifically, the liquid ejected from the auxiliary opening 112 can have a relatively shorter spray distance compared to the injection opening 121.
[0096] In particular, the sum of the areas of the auxiliary openings 112 located at the same longitudinal position along the longitudinal axis L that penetrate the pipe wall 11 can be greater than the area of the injection opening 121 that penetrates the pipe wall 11. This also helps to ensure that the liquid ejected from the auxiliary openings 112 has the desired spray distance.
[0097] See Figure 2 The pipe wall 11 may be provided with two sets of auxiliary openings 112 arranged in the longitudinal direction. Each set of auxiliary openings 112 includes at least two auxiliary openings 112. Each set of auxiliary openings 112 is located at the same longitudinal position in the direction of the longitudinal axis L. For example, each set of auxiliary openings 112 may be arranged around the longitudinal axis L.
[0098] Figure 2 It is also shown that the injector 1 may be provided with a mounting ring 13 projecting outward from the pipe wall 11, the mounting ring 13 extending around the pipe wall 11 in a ring plane. The injector 1 can be mounted to the door seal 5 by means of the mounting ring 13. The ring plane may be inclined relative to a plane perpendicular to the longitudinal axis L. This helps to achieve the desired spray distance and spray range. Along the main spray direction D S Observation shows that the angle θ of the annular plane relative to the plane perpendicular to the longitudinal axis L can be particularly between 2° and 5°.
[0099] The injector 1 can further be provided with tabs 14 arranged in a non-rotationally symmetrical manner with respect to the longitudinal axis L, which tabs 14 project outwardly with respect to the tube wall 11 and extend along the longitudinal axis L. The tabs 14 can serve to ensure that the injector 1 is correctly installed in place and to prevent unwanted rotation of the injector 1.
[0100] The tabs 14 can be arranged closer to the inlet 111 than the mounting ring 13.
[0101] Referring to Figure 3 at least in the end of the tabs 14 closer to the inlet 111, the dimension by which the tabs 14 project outwardly with respect to the tube wall 11 can decrease in the direction along the longitudinal axis L towards the inlet 111. This can enable more convenient installation of the injector 1.
[0102] Figure 6 and Figure 7 Part components of a laundry care appliance according to exemplary embodiments of the present application are schematically shown in a front view and in a sectional view.
[0103] Figure 6 and Figure 7 A door seal 5 and an injector 1 of a laundry care appliance are shown. The door seal 5 is circular annular, and the injector 1 is mounted to the door seal 5.
[0104] The injector 1 can be arranged such that its longitudinal axis L is inclined with respect to the radial direction of the door seal 5, such that the nozzle 12 of the injector 1 is offset upwards in the height direction of the laundry care appliance. This contributes to achieving a desired spray range, such that the spray range comprehensively covers the laundry 20 within the laundry drum 2.
[0105] In Figure 7 a door 4 of a laundry care appliance is schematically shown in dashed lines. The injector 1 is arranged such that the nozzle 12 is located on a side facing away from the door 4.
[0106] At least one of the auxiliary openings 112 can be provided on a side of the tube wall 11 opposite the nozzle 12 and open in a direction away from the main spray direction D S Thereby, at least one of the auxiliary openings 112 opens towards the door 4. Thereby, it can be ensured that liquid flowing out of the auxiliary openings 112 is able to rinse the door 4 or the door seal 5 of the laundry care appliance.
