Abstract
Description
Technical Field
[0001] This invention belongs to the field of cleaning equipment technology, and more specifically, relates to a washing machine. Background Technology
[0002] Washing machines are machines that use electric power to generate mechanical force to clean clothes. For clothes such as shirts, the collar and cuffs are generally dirtier than other areas. However, existing washing machines are not very effective at cleaning these areas during the washing process.
[0003] In existing technologies, ultrasonic washing is often required to achieve the desired result by adding an ultrasonic washing function to the washing machine.
[0004] For example, Chinese Patent Application No. CN200520069251.1 discloses a washing machine with a local ultrasonic washing device, including a washing machine body and an ultrasonic washing device. The ultrasonic washing device consists of an ultrasonic generator, a transducer, a device housing, and a transducer base. The ultrasonic generator is installed in a computer board and connected to the transducer. The transducer is installed on the base inside the device housing and is pressed down by a cover plate. The ultrasonic washing device is fixed by a positioning support and is installed at the rear of the washing machine's worktable via the positioning support.
[0005] Chinese patent application number CN2017101131757 discloses a partial cleaning structure for clothing and a washing machine. The partial cleaning structure for clothing is detachably mounted on the washing machine tray and connected to the washing machine's water inlet / detergent box. The partial cleaning structure for clothing includes a pressure plate and a support plate. The pressure plate includes an ultrasonic transducer, and the support plate includes a water inlet cavity. The shape of the pressure plate matches the support plate. After being pressed towards the support plate, a narrow slit is formed between them to clamp the part of the clothing to be washed, clamping the clothing and ultrasonically cleaning the part to be washed.
[0006] While the above solution addresses the issue of washing machines being unable to clean heavily soiled areas to some extent, adding ultrasonic washing to the washing machine undoubtedly increases its cost and reduces its market competitiveness.
[0007] In view of this, the present invention is proposed. Summary of the Invention
[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing machine that uses the water inlet component of the washing machine as the water outlet structure for the auxiliary washing stage, and the detection device controls whether it is started. During the local cleaning process, the process of wetting clothes and adding detergent can be carried out alternately, which improves the cleaning effect on local areas and simplifies the structure of the washing machine while increasing the functions of the washing machine.
[0009] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:
[0010] A washing machine, comprising:
[0011] Box;
[0012] A tray base is disposed above the box body, and the tray base has a clothing loading port;
[0013] A bucket assembly is disposed inside the box, and the opening of the bucket assembly corresponds to the clothing loading port;

In the main water inlet stage, it is configured to introduce water into the tub assembly, and in the auxiliary water inlet stage, it is configured to spray water onto the clothes to be washed.
[0015] The detection device is configured to generate a start signal to activate the water inlet component when a signal indicating that the laundry is approaching is detected during the auxiliary water inlet phase, and to generate a stop signal to deactivate the water inlet component when no signal indicating that the laundry is approaching is detected during the auxiliary water inlet phase.
[0016] Furthermore, it also includes:

[0023] A turbidity detection unit is installed inside the tank assembly and is used to detect the turbidity of the water inside the tank assembly;
[0024] A drainage assembly, connected to the bucket assembly, is used to drain water from the bucket assembly;
[0025] At the end of the auxiliary water intake phase, when the turbidity of the water in the tank assembly exceeds a set threshold, the drain assembly is controlled to open and drain the water from the tank assembly.
[0026] Furthermore, before the main water intake phase begins, when the turbidity of the water in the tub assembly does not exceed a set threshold, the water intake volume of the water intake assembly in the main water intake phase is controlled to be the difference between the preset water intake volume in the selected washing program and the water intake volume in the auxiliary water intake phase.
[0027] Furthermore, the water inlet assembly also includes:
[0028] A water box is disposed on the tray base, and the outlet of the water box falls into the coverage area of the opening of the bucket assembly;
[0029] The main detergent dispensing device is located inside the water tank and is used to dispense detergent into the water tank in a measured amount.
[0030] Before the main water intake stage begins, the detergent dosage of the auxiliary detergent dispensing device is obtained, and the amount of detergent dispensed into the water tank by the main detergent dispensing device is adjusted according to the detergent dosage of the auxiliary detergent dispensing device.
[0031] Furthermore, the detection device sequentially generates activation signals to start the water inlet assembly or the auxiliary detergent dispensing device as the number of detections increases.
[0032] Furthermore, the detection device includes:
[0033] The first detection unit is configured to generate a start signal to activate the auxiliary detergent dispensing device when a signal indicating that the laundry is approaching is detected, and to generate a stop signal to deactivate the auxiliary detergent dispensing device when no signal indicating that the laundry is approaching is detected.
[0034] The second detection unit is configured to generate a start signal to activate the water inlet component when a signal indicating that the laundry is approaching is detected during the auxiliary water inlet phase, and to generate a stop signal to deactivate the water inlet component when no signal indicating that the laundry is approaching is detected during the auxiliary water inlet phase.
[0035] Furthermore, the detection device is any one of the following:
[0036] Infrared sensing unit, voice recognition module, position sensor.
[0037] Furthermore, the auxiliary detergent dispensing device is a foam-type detergent dispensing device;
[0038] Preferably, the auxiliary detergent dispensing device includes:
[0039] A liquid storage bottle is disposed within the tray base;

[0045] A drive mechanism for driving the liquid pump and the gas pump is configured to receive a signal to start / stop the auxiliary detergent dispensing device.
[0046] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.
[0047] 1. This invention provides an auxiliary detergent dispensing device that sprays detergent onto the washing tray, while utilizing the washing machine's water inlet assembly as the water outlet structure for the auxiliary washing stage. The device controls whether the device is activated. During localized cleaning, the processes of wetting clothes and adding detergent can be alternated, improving the cleaning effect on specific areas and simplifying the structure of the washing machine while increasing its functionality.
[0048] 2. This invention only requires one detection device to control the water inlet component and the auxiliary detergent dispensing device, reducing the number of washing machine parts, simplifying assembly, and saving equipment costs.
[0049] 3.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0060] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.
[0061] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0062] like Figures 1 to 5As shown, the present invention provides a washing machine, including a housing 1, a tub assembly disposed inside the housing 1, and a tray base 2 disposed on the top of the housing 1. The tray base 2 has a clothes inlet 3, which corresponds to the top opening of the tub assembly, and the tray base 2 is also provided with a cover 9 for opening and closing the clothes inlet 3.
[0063] The washing machine also includes a water inlet assembly 5, which is connected to the drum base 2 and has a main water inlet stage and an auxiliary water inlet stage. In the main water inlet stage, it is configured to introduce water into the drum assembly, and in the auxiliary water inlet stage, it is configured to spray water onto the clothes 10 to be washed.
[0064] The aforementioned water inlet component 5 is not controlled by the washing machine's preset washing program during the auxiliary water inlet stage, but is controlled by the detection device 6.
[0065] This invention utilizes the water inlet component 5 of the washing machine as the water outlet structure for the auxiliary washing stage, and the detection device 6 controls whether it is activated. During the local cleaning process, the process of wetting clothes and adding detergent can be carried out alternately, which improves the cleaning effect on local areas and simplifies the structure of the washing machine while increasing its functions.
[0066] The washing machine also includes an auxiliary detergent dispensing device 4, which is connected to the tray 2 and is used to spray detergent into the clothes dispensing port 3.
[0067] Therefore, the washing machine also includes a detection device 6, which is configured to generate a start signal to activate the auxiliary detergent dispensing device 4 or the water inlet assembly 5 after detecting a signal that the laundry 10 is approaching, and to generate a stop signal to deactivate the auxiliary detergent dispensing device 4 or the water inlet assembly 5 after not detecting a signal that the laundry 10 is approaching.
[0068] It should be noted that the detection device controls the start and stop of the water inlet component 5 during the auxiliary water inlet stage.
[0069] In some embodiments of the present invention, the washing machine further includes a control panel 7, which is provided with a program selector and additional function selection buttons, etc. The control panel 7 is disposed on the tray base 2. In particular, the control panel 7 provided by the present invention is provided with control buttons 8, which are configured to control whether the detection device 6 generates a start signal to start the auxiliary detergent dispensing device 4 or the water inlet assembly 5.
[0070] Detailed, such as Figure 4As shown, since the water inlet assembly 5 and the auxiliary detergent dispensing device 4 are both located on the tray base 2, the user will inevitably pass through the detection device 6 when putting clothes into the drum assembly. To avoid the detection device 6 being accidentally triggered, the present invention provides a control button 8 on the control panel 7. Only when the control button 8 is in the selected state will the detection device 6 detect whether there is a garment 10 to be washed approaching. Otherwise, the detection device 6 will not detect whether there is a garment 10 to be washed approaching.
[0071] The above solution makes the logic of the washing machine of the present invention more reasonable in the process of controlling the water inlet component 5 and the auxiliary detergent dispensing device 4 in the auxiliary water inlet stage, and reduces the possibility of being triggered erroneously.
[0072] In some embodiments of the present invention, the water inlet component 5 includes a flow rate adjustment unit configured to adjust the water inlet flow rate of the auxiliary water inlet stage to 40% to 80% of the water inlet flow rate of the main water inlet stage after detecting that the control button 8 is selected.
[0073] In detail, the function of the aforementioned water inlet component 5 in the main water inlet stage is to introduce water into the tub assembly. Therefore, the water inlet component 5 may also include a main detergent dispensing device, which dilutes the detergent or dissolves the laundry powder while introducing water into the tub assembly during the main water inlet stage. Therefore, the water flow rate of the water inlet component 5 is generally relatively high during the main water inlet stage, partly to dissolve the laundry powder or dilute the detergent, and partly to reduce the overall washing cycle time.
[0074] However, during the auxiliary water intake stage, the function of the water intake component 5 is to spray water to wet a local area of the clothes 10 to be washed. If the water flow rate is too high, it may cause water droplets to splash. Moreover, local areas generally use less water, so if the water flow rate is too high, it will also waste water.
[0075] Therefore, in some embodiments of the present invention, the water outlet speed of the water inlet component 5 at different stages is further limited. That is, by setting a flow rate adjustment unit, when the function of the water inlet component 5 is to wet a local area of the garment 10 to be washed, the water outlet speed is adjusted to 40% to 80% of the water outlet speed of the main water inlet stage.
[0076] In a preferred embodiment, a separate water flow rate selector can also be set on the control panel 7, allowing the user to determine the water flow rate.
[0077] In some embodiments of the present invention, the washing machine further includes a turbidity detection unit disposed within the tub assembly for detecting the turbidity of the water within the tub assembly.
[0078] The washing machine also includes a drain assembly, which is connected to the tub assembly and is used to drain water from the tub assembly.
[0079] At the end of the auxiliary water intake phase, when the turbidity of the water in the tank assembly exceeds a set threshold, the drain assembly is controlled to open and drain the water from the tank assembly.
[0080] In detail, the auxiliary detergent dispensing device 4 is installed on the tray base 2, which sprays detergent into the clothes dispensing port 3 of the tray base 2. The water inlet component 5 is also installed on the tray base 2. It can be seen that when cleaning a part of the clothes 10 to be washed, the washing tub is configured to hold detergent and water.
[0081] However, when a particular area is heavily soiled, the turbidity of the wash water after cleaning that area is high, making it unsuitable for reuse to wash other clothes. Therefore, this invention incorporates a turbidity detection unit within the tub assembly. When control button 8 is triggered, the turbidity of the water in the tub assembly is detected before the main water inlet. If the control unit determines that the turbidity of the water in the tub assembly is high, it activates the drain assembly to discharge the wastewater before starting the subsequent washing cycle. If the control unit determines that the turbidity of the water in the tub assembly is low, it indicates that this portion can be recycled and does not need to be discharged.
[0082] The above method can improve the washing ratio of clothes and avoid damage to the clothes to be washed by water with high turbidity.
[0083] In a further embodiment, before the main water intake stage begins, when the turbidity of the water in the tub assembly does not exceed a set threshold, the water intake component 5 is controlled to have a water intake amount in the main water intake stage that is the difference between the preset water intake amount in the selected washing program and the water intake amount in the auxiliary water intake stage.
[0084] In detail, the water inlet assembly 5 also includes a flow detection unit. During the auxiliary water inlet stage, the total flow rate of the water is detected. When the turbidity of the water in the tub assembly is low after the local washing is completed, the control unit obtains the preset water inlet amount in the user-selected washing program and the total water inlet amount during the auxiliary water inlet stage. During the main water inlet stage, the water inlet assembly 5 is controlled to supply water into the tub assembly in a way that is the difference between the preset water inlet amount in the user-selected washing program and the total water inlet amount during the auxiliary water inlet stage.
[0085] The above solution can prevent accidents such as overflow caused by high water levels inside the drum assembly during the washing process.
[0086] It should be noted that the flow detection unit is only one feasible implementation method to achieve the above function. In other feasible implementation methods, for example, the water level detection unit can also be set in the tank assembly to achieve the above function.
[0087] In some embodiments of the present invention, the water inlet assembly 5 further includes a water box disposed on the tray base 2, and the outlet of the water box falls into the coverage area of the opening of the bucket assembly.
[0088] The main detergent dispensing device is installed inside the water tank and is used to dispense detergent into the water tank in a measured amount. Before the main water intake stage begins, the amount of detergent dispensed by the auxiliary detergent dispensing device 4 is obtained, and the amount of detergent dispensed by the main detergent dispensing device into the water tank is adjusted according to the amount of detergent dispensed by the auxiliary detergent dispensing device 4.
[0089] In detail, the aforementioned main detergent dispensing device is a detergent dispensing device with an automatic dispensing function. For example, the main detergent dispensing device includes a storage bottle, a negative pressure suction unit, a metering pump, etc. It automatically dispenses detergent into the water box during the main water intake stage, and the detergent is flushed into the tub assembly by the incoming water.
[0090] When the turbidity of the water in the tub is low, this water will be reused. However, this water will have already dissolved some detergent. If the detergent is added according to the preset amount in the user's selected washing program, the detergent concentration in the water will be high, resulting in incomplete rinsing.
[0091] Therefore, before the main water intake stage begins, the control unit obtains the detergent dosage of the auxiliary detergent dispensing device 4, and then adjusts the amount of detergent dispensed into the water tank by the main detergent dispensing device according to the detergent dosage of the auxiliary detergent dispensing device 4.
[0092] For example, if the user selects a washing program with a preset automatic detergent dispensing amount of M, and during spot cleaning, the auxiliary detergent dispensing device 4 dispenses N amounts of detergent, then during the main water intake stage, the amount of detergent Q dispensed by the main detergent dispensing device into the water tank is K×(MN). Here, K is an adjustment coefficient, typically determined through multiple laboratory experiments, and its value ranges from 1.2 to 1.5.
[0093] In some embodiments of the present invention, the detection device 6 generates, in turn, a start signal to activate the water inlet component 5 or the auxiliary detergent dispensing device 4 as the number of detections increases.
[0094] The detection device 6 sequentially generates a start signal to activate the water inlet component 5, a stop signal to deactivate the water inlet component 5, a start signal to activate the auxiliary detergent dispensing device 4, and a stop signal to deactivate the auxiliary detergent dispensing device 4.
[0095] In detail, during use, such as Figure 2As shown, when the detection device 6 detects the laundry 10 approaching, it generates a start signal to activate the water inlet assembly 5 and sends the start signal to the water inlet assembly 5. Upon receiving the start signal, the water inlet assembly 5 sprays water to wet the laundry 10. When the user determines that the clothes are thoroughly wet, they move the clothes out of the detection range of the detection device 6. When the detection device 6 no longer detects the approaching clothes, it generates a stop signal to shut off the water inlet assembly 5 and sends the stop signal to the water inlet assembly 5. Upon receiving the stop signal, the water inlet assembly 5 stops spraying water. Figure 1 As shown, when the detection device 6 detects the laundry 10 approaching again, it generates a start signal to activate the auxiliary detergent dispensing device 4 and sends the start signal to the auxiliary detergent dispensing device 4. Upon receiving the start signal, the auxiliary detergent dispensing device 4 sprays detergent into the laundry dispensing port 3, applying it to the laundry 10. When the user determines that an appropriate amount of detergent has been sprayed, the user moves the laundry away from the detection range of the detection device 6. After the detection device 6 no longer detects the laundry approaching, it generates a stop signal to shut down the auxiliary detergent dispensing device 4 and sends the stop signal to the laundry dispensing device. Upon receiving the stop signal, the auxiliary detergent dispensing device 4 stops spraying detergent into the laundry dispensing port 3.
[0096] Thus, as Figure 3 As shown, the garment 10 to be washed is wetted and coated with detergent. After the user rubs the garment 10 and visually assesses that the stains have been removed, the user brings the garment 10 close to the detection device 6 again. When the detection device 6 detects the garment 10 approaching, it generates a start signal to activate the water inlet assembly 5 and sends the start signal to the water inlet assembly 5. Upon receiving the start signal, the water inlet assembly 5 sprays water again to rinse the detergent foam off the garment 10.
[0097] After the detergent foam is rinsed off, the user visually inspects whether the stains on the garment 10 have been cleaned. If clean, the user moves the garment away from the detection range of the detection device 6. Once the detection device 6 no longer detects the garment's proximity, it generates a shutdown signal to shut off the water inlet assembly 5 and sends this signal to the assembly. Upon receiving the shutdown signal, the water inlet assembly 5 stops spraying water. If the garment is still not clean, the user can bring it close to the detection device 6 again. When the detection device 6 detects the garment 10 again, it generates a start signal to activate the auxiliary detergent dispensing device 4 and sends this signal to the device. Upon receiving the start signal, the auxiliary detergent dispensing device 4 sprays detergent into the garment dispensing port 3, applying it to the garment 10. Once the user determines that an appropriate amount of detergent has been sprayed, the user moves the garment away from the detection range of the detection device 6. Once the detection device 6 no longer detects the garment's proximity, it generates a shutdown signal to shut off the auxiliary detergent dispensing device 4 and sends this signal to the washing dispensing device. Upon receiving the shutdown signal, the auxiliary detergent dispensing device 4 stops spraying detergent into the garment dispensing port 3.
[0098] Users can control whether clothes are close to the detection device 6 according to the actual situation, so that the spray water and the spray detergent alternate, improving the cleaning effect on local areas.
[0099] In the above scheme, only one detection device 6 is needed to control the water inlet component 5 and the auxiliary detergent dispensing device 4, reducing the number of washing machine parts, simplifying the assembly relationship, and saving equipment costs.
[0100] In terms of location, the detection device 6 can be set in the intersection area controlled by the water inlet component 5 and the washing dispensing device.
[0101] In some embodiments of the present invention, the detection device 6 includes a first detection unit and a second detection unit.
[0102] The first detection unit is configured to generate a start signal to activate the auxiliary detergent dispensing device 4 when a signal indicating that the laundry 10 is approaching is detected, and to generate a shut-off signal to deactivate the auxiliary detergent dispensing device 4 when no signal indicating that the laundry 10 is approaching is detected.
[0103] The second detection unit is configured to generate a start signal to activate the water inlet component 5 when a signal indicating that the laundry 10 is approaching is detected during the auxiliary water inlet stage, and to generate a stop signal to deactivate the water inlet component 5 when no signal indicating that the laundry 10 is approaching is detected during the auxiliary water inlet stage.
[0104] In detail, during use, when the second detection unit detects the laundry 10 approaching, it generates a start signal to activate the water inlet assembly 5 and sends the start signal to the water inlet assembly 5. Upon receiving the start signal, the water inlet assembly 5 sprays water to wet the laundry 10. When the user determines that the clothes are thoroughly wet, they move the clothes out of the detection range of the second detection unit. After the second detection unit no longer detects the approaching clothes, it generates a stop signal to shut off the water inlet assembly 5 and sends the stop signal to the water inlet assembly 5. Upon receiving the stop signal, the water inlet assembly 5 stops spraying water. When the first detection unit detects the laundry 10 approaching, it generates a start signal to activate the auxiliary detergent dispensing device 4 and sends the start signal to the auxiliary detergent dispensing device 4. Upon receiving the start signal, the auxiliary detergent dispensing device 4 sprays detergent into the laundry dispensing port 3 and applies it to the laundry 10. When the user determines that an appropriate amount of detergent has been sprayed, the user moves the clothes away from the detection range of the first detection unit. After the first detection unit no longer detects the signal of the clothes approaching, it generates a shutdown signal to shut down the auxiliary detergent dispensing device 4 and sends the shutdown signal to the detergent dispensing device. After receiving the shutdown signal, the auxiliary detergent dispensing device 4 stops spraying detergent into the clothes dispensing port 3.
[0105] At this point, the garment 10 is wetted and coated with detergent. After the user rubs the garment 10 and visually assesses that the stains have been removed, the user brings the garment 10 close to the second detection unit again. When the second detection unit detects the garment 10 approaching, it generates a start signal to activate the water inlet assembly 5 and sends the signal to the assembly. Upon receiving the start signal, the water inlet assembly 5 sprays water to rinse the detergent foam off the garment 10.
[0106] After the detergent foam is rinsed off, the user visually inspects whether the stains on the garment 10 have been cleaned. If clean, the user moves the garment away from the detection range of the second detection unit. Once the second detection unit no longer detects the garment's proximity, it generates a shutdown signal to shut off the water inlet assembly 5 and sends this signal to the assembly. Upon receiving the shutdown signal, the water inlet assembly 5 stops spraying water. If the garment is still not clean, the user can bring it close to the first detection unit again. When the first detection unit detects the garment 10 approaching, it generates a start signal to activate the auxiliary detergent dispensing device 4 and sends this signal to the device. Upon receiving the start signal, the auxiliary detergent dispensing device 4 sprays detergent into the garment dispensing port 3, applying it to the garment 10. Once the user determines that an appropriate amount of detergent has been sprayed, the user moves the garment away from the detection range of the first detection unit. Once the first detection unit no longer detects the garment's proximity, it generates a shutdown signal to shut off the auxiliary detergent dispensing device 4 and sends this signal to the washing dispensing device. Upon receiving the shutdown signal, the auxiliary detergent dispensing device 4 stops spraying detergent into the garment dispensing port 3.
[0107] Users can control the number of times clothing is brought close to the first and second detection units according to the actual situation, so that water spray and detergent spray alternate, improving the cleaning effect on local areas.
[0108] In the above scheme, two detection units are set up to control the water inlet component 5 and the auxiliary detergent dispensing device 4 separately, which improves the flexibility of control over the water inlet component 5 and the auxiliary detergent dispensing device 4, is more in line with user habits, and improves user experience.
[0109] In terms of location, the first detection unit and the second detection unit can be respectively located near the washing dispensing device and the water inlet component 5.
[0110] In some embodiments of the present invention, the detection device 6 can be any one of an infrared sensing unit, a voice recognition module, or a position sensor.
[0111] The infrared sensing unit and the position sensor can send a start or stop signal by sensing the distance between the laundry 10 and the detection device 6.
[0112] The voice recognition module can send start or stop signals by recognizing voice control commands such as "start detergent", "stop detergent", "start water flow", and "stop water flow".
[0113] In some embodiments of the present invention, the auxiliary detergent dispensing device 4 is a foam-type auxiliary detergent dispensing device 4.
[0114] In the above scheme, the detergent dispensed by the auxiliary detergent dispensing device 4 is foam-type, which makes the detergent foam finer and also eliminates the need for the user to rub and generate foam, saving time.
[0115] Specifically, the auxiliary detergent dispensing device 4 includes a storage bottle, a dispensing pipe, and a foam generating device. The storage bottle is disposed inside the tray 2; the dispensing pipe is disposed on the side wall of the clothing dispensing port 3, and the outlet of the dispensing pipe extends out of the side wall of the tray 2 and is located inside the clothing dispensing port 3.
