Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing equipment, and in particular to a clothing processing equipment and a washing control method of the clothing processing equipment. Background Art

[0002] Detergent foam can play a good role in cleaning and softening clothes during the washing process. Currently, existing clothing processing equipment usually does not have an active foam generating device. It takes a period of time to generate foam. The detergent takes a long time to take effect, and some detergents cannot be completely dissolved in water, affecting the cleaning effect.

[0003] Some washing machines are equipped with a foam generating device, and there are mainly two technical solutions: one is to generate foam when the detergent is added into the water, and spray it from the top to the surface of the clothes. After the detergent is added, there is no foaming function, and the clothing cleaning effect is poor; the other is to set a foam generator at the bottom of the outer drum or at the drain pipe. The foam cannot directly cover the surface of the clothes, and the cleaning effect is not ideal. In addition, the user cannot directly observe the foam spraying process, and it is difficult to intuitively feel the effect of the foam washing. Summary of the invention

[0004] In order to overcome the problem that the foam generating device in the existing clothing treatment device cannot continuously apply foam to the surface of the clothes when washing clothes, thus resulting in poor clothing cleaning effect, the embodiment of the present invention proposes a clothing treatment device and a washing control method for the clothing treatment device, which discharges the washing water in the clothing treatment drum into the foam generating device for foaming treatment, and after foaming, discharges the foam into the clothing treatment drum from the top position of the clothing treatment drum again. On the one hand, the foam generating device draws water in the clothing treatment drum, and can continuously use the washing water in the clothing treatment drum for foaming during the washing process of the clothes. On the other hand, by arranging the liquid discharge end of the bubble delivery pipe of the foam generating device at the top of the clothing treatment drum, the detergent foam entering the clothing treatment drum can cover the surface of the clothes in the clothing treatment drum from top to bottom, thereby improving the clothing cleaning effect, and the user can also intuitively observe the foam spraying process through the clothing introduction port of the clothing treatment drum, so as to intuitively feel the foam washing effect.

[0067] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0068] The foam generating device in the existing clothing treatment equipment cannot continuously apply foam to the surface of clothing when washing clothing, resulting in poor clothing washing effect. The embodiment of the present invention proposes a clothing treatment equipment and a washing control method for the clothing treatment equipment, which discharges the washing water at the bottom of the clothing treatment drum into the foam generating device for foaming treatment, and after foaming, the foam is discharged from the top position of the clothing treatment drum into the clothing treatment drum again. On the one hand, the foam generating device draws water in the clothing treatment drum, and can continuously use the washing water in the clothing treatment drum for foaming during the washing process of the clothing. On the other hand, by setting the liquid discharge end of the bubble pipe of the foam generating device at the top of the clothing treatment drum, the detergent foam entering the clothing treatment drum can cover the surface of the clothing in the clothing treatment drum from top to bottom, thereby improving the clothing washing effect. At the same time, the user can also intuitively observe the foam spraying process through the clothing delivery port of the clothing treatment drum, so that the foam washing effect can be intuitively felt.

[0069] The following is combined with Figure 1 -Attached Figure 4 The technical solution of this embodiment is elaborated in detail. In the absence of conflict, the following implementation methods and embodiments can be combined with each other.

[0070] Example

[0071] like Figure 1 and Figure 2 As shown, a first aspect of an embodiment of the present invention provides a clothes processing device, comprising:

[0072] Clothes treatment drum 90;

[0073] A foam generating device 1, comprising a foam generating chamber and a foaming device for foaming liquid in the foam generating chamber, wherein the foam generating chamber has a liquid inlet 101 and a foam outlet 301;

[0074] The liquid inlet side of the liquid inlet 101 is connected to the clothing processing drum through the liquid inlet pipe, and the bubble delivery side of the bubble discharge port 301 is connected to the clothing processing drum 90 through the bubble delivery pipe 302, and the connection position between the bubble delivery pipe 302 and the clothing processing drum 90 is located at the top of the clothing processing drum 90.

[0075] In the embodiment of the present invention, the washing water in the clothing treatment drum 90 is discharged into the foam generating device 1 for foaming treatment, and the foam is discharged into the clothing treatment drum 90 again from the top position of the clothing treatment drum 90 after foaming. On the one hand, the foam generating device draws water in the clothing treatment drum 90, and can continuously utilize the washing water in the clothing treatment drum 90 for foaming during the washing process of the clothes. On the other hand, the discharge end of the bubble delivery tube 302 of the foam generating device 1 is set at the top of the clothing treatment drum 90, so that the detergent foam entering the clothing treatment drum can cover the surface of the clothes in the clothing treatment drum from top to bottom, thereby improving the clothing washing effect while the user can also intuitively observe the foam spraying process through the clothing inlet of the clothing treatment drum, so as to intuitively feel the foam washing effect.

[0076] Preferably, the above-mentioned clothing processing device is a washing machine or a washer-dryer.

[0077] In some embodiments, Figure 1 and Figure 2 As shown, the foam generating device 1 is disposed below the laundry processing tub 90, and the laundry processing tub 90 is connected to the foam generating device 1 through the liquid inlet 101 and the bubble outlet 301 of the foam generating device to form a circulation passage;

[0078] The foamer includes an aeration module 40 arranged in the foam generating chamber and an air pump 60 arranged outside the foam generating chamber, and the exhaust end of the air pump 60 is connected to the aeration module 40: preferably, the aeration module 40 is a porous, mesh foamer, or a negative pressure jet device.

[0079] The clothes treatment drum 90 and the foam generating device 1 constitute a circulation path. When the air pump 60 is turned off, the washing water in the clothes treatment drum 90 can enter the foam generating chamber under the action of gravity. When the air pump 60 is turned on, the washing water in the clothes treatment drum 90 stops entering the foam generating chamber, and the turned-on air pump 60 can drive the aeration module 40 to foam the washing water in the foam generating chamber.

[0080] Since the foam generating device 1 and the clothing treatment drum 90 form a circulating passage, when the air pump 60 is turned off, there is no intake pressure in the foam generating device 1. At this time, the washing water in the clothing treatment drum 90 can enter the foam generating chamber of the foam generating device by its own gravity. When the air pump 60 is turned on, since there is intake pressure in the foam generating device 1, the washing water in the clothing treatment drum 90 cannot enter the foam generating chamber of the foam generating device 1 by its own gravity due to the pressure difference. At this time, the foam generated by the foam generating device 1 can be pressed into the clothing treatment drum 90 through the bubble tube 302 under the action of the intake pressure. At the same time, if there is washing water in the foam generating chamber, the washing water in the foam generating chamber can also be pressed into the clothing treatment drum 90 through the bubble tube 302 under the action of the pressure difference.

[0081] That is, in the embodiment of the present invention, by reasonably controlling the opening of the air pump 60, on the one hand, the automatic water inlet effect and the automatic water inlet stop effect of the foam generating device 1 can be achieved, and on the other hand, the water inlet amount of the foam generating device 1 can be reasonably controlled, thereby ensuring the automatic water inlet and stop effects while improving the foaming effect of the foam generating device 1, thereby improving the washing effect of the clothing processing equipment on the clothes.

[0082] In some embodiments, Figure 1 and Figure 2 As shown, the clothing treatment device further includes a gas generator 70 capable of generating sterilizing gas, and the gas generator 70 is connected to the air inlet end of the air pump 60 .

[0083] In the embodiment of the present invention, a gas generator 70 with a sterilizing effect is provided, so that a gas with a sterilizing effect can be incorporated into the foam when the foam generating device foams, so that when the foam is input to a designated location to process the object to be processed, the object to be processed can also be sterilized.

[0084] Preferably, the gas generator 70 is an ozone generator. Taking the foam generating device disposed in the clothing processing device as an example, the foam generated by the foam generating device can be applied to the clothing in the clothing processing device, thereby improving the washing effect of the clothing, and at the same time, the foam infused with ozone can also sterilize the clothing when in contact with the clothing, thereby further improving the washing effect of the clothing.

[0085] It should be noted that in terms of healthy sterilization, the sterilizing gas produced by a gas generator with good sterilization effect, such as an ozone generator, is difficult to dissolve in water and cannot play a good sterilization role during the washing process. However, it can adhere to the surface of the foam and be wrapped inside the foam, achieving a good sterilization effect during the contact between the foam and the clothes. In this embodiment, by connecting the ozone generator and the foamer together, the sterilizing gas can be attached to the surface of the detergent foam, and follow the detergent foam into the clothing treatment drum to act on the surface of the clothing, thereby sterilizing the clothing.

[0086] In some embodiments, a liquid inlet one-way valve 104 is provided on the liquid inlet pipe, and the liquid inlet one-way valve 104 is designed to allow liquid to flow into the foam generating chamber through the liquid inlet pipe and restrict the liquid in the foam generating chamber from flowing out through the liquid inlet pipe.

[0087] An exhaust pipe 103 is also provided between the air pump 60 and the aeration module 40 , and an exhaust check valve 105 is provided on the exhaust pipe 103 . The exhaust check valve 105 is designed to allow gas to enter the foam generating chamber through the exhaust pipe 103 and limit the liquid in the foam generating chamber from being discharged through the exhaust pipe 103 .

[0088] In the embodiment of the present invention, a liquid inlet check valve 104 is provided on the liquid inlet pipe, so as to ensure that during the ventilation and foaming process of the foam generating device, the washing liquid in the foam generating chamber will not be discharged through the liquid inlet pipe under the action of air pressure. By providing an exhaust check valve 105 on the exhaust pipe 103, it can be ensured that during the liquid inlet process of the foam generating chamber, the washing liquid in the foam generating chamber will not enter the air pump 60 and the gas generator 70 through the exhaust pipe 103, so as to avoid damage to the devices.

[0089] In some embodiments, Figure 1 and Figure 2 As shown, the foam generating chamber includes a liquid inlet chamber 10, a liquid discharge chamber 20 and a foam chamber 30. The liquid inlet chamber 10 and the liquid discharge chamber 20 are arranged adjacent to each other, and the liquid inlet chamber 10 and the liquid discharge chamber 20 are separated at the bottom and connected at the top. The liquid discharge chamber 20 and the foam chamber 30 are arranged adjacent to each other, and the liquid discharge chamber 20 and the foam chamber 30 are separated at the bottom and connected at the top.

[0090] The bottom of the liquid inlet chamber 10 is provided with a liquid inlet port 101 , the bottom of the foam chamber 30 is provided with a bubble outlet port 301 , and the aeration module 40 is disposed at the bottom of the liquid inlet chamber 10 .

[0091] In the embodiment of the present invention, the foam generating chamber is arranged into a liquid inlet chamber 10, a liquid discharge chamber 20 and a foaming chamber 30, and the liquid inlet chamber 10 and the liquid discharge chamber 20 are arranged adjacent to each other, and the liquid discharge chamber 20 and the foam chamber 30 are arranged adjacent to each other. At the same time, the liquid inlet port of the liquid inlet chamber 10 is arranged at the bottom, and the bubble discharge port 301 of the foam chamber 30 is arranged at the bottom. In this way, the washing liquid can enter the liquid inlet chamber 10 from the bottom of the liquid inlet chamber 10 and be foamed through the aeration module 40. The foamed foam can enter the discharge chamber 20 and the foaming chamber 30 in turn through the top of the liquid inlet chamber 10, and finally be discharged to the designated action position through the foaming port 301 of the foaming chamber 30. When the washing liquid in the liquid inlet chamber 10 is consumed, the washing liquid can enter the liquid inlet chamber again through the liquid inlet port 101 at the bottom of the liquid inlet chamber 10. Since the liquid enters from the bottom of the liquid inlet chamber 10, the washing liquid that enters the liquid inlet chamber 10 again can discharge the low-concentration washing liquid remaining at the bottom of the liquid inlet chamber 10 after the last foaming is completed into the discharge chamber 20 adjacent to the liquid inlet chamber 10 for storage, thereby avoiding the low-concentration washing liquid directly entering the foaming chamber 30 and blocking the foaming port 301 of the foaming chamber 30, thereby ensuring the foaming effect of the liquid inlet chamber 10 while ensuring the foam delivery effect of the foam chamber 30.

[0092] It should be noted that the embodiment of the present invention can ensure that all foam entering the foam cavity 30 is discharged by setting the bubble discharge port 301 of the foam cavity 30 at the bottom, thereby avoiding residual foam in the foam cavity 30 due to the bubble discharge port 301 being set too high.

[0093] It should also be noted that the liquid inlet chamber 10, the liquid discharge chamber 20 and the foam chamber 30 in the embodiment of the present invention may be arranged adjacent to each other in sequence along a certain direction, or may not be arranged adjacent to each other in sequence along a certain direction, as long as the liquid inlet chamber 10 and the liquid discharge chamber 20 are arranged adjacent to each other, and the liquid discharge chamber 20 and the foam chamber 30 are arranged adjacent to each other. However, it is relatively preferred that the liquid inlet chamber 10, the liquid discharge chamber 20 and the foam chamber 30 are arranged adjacent to each other in sequence along a certain direction.

[0094] Preferably, the bottom surface position of the liquid inlet chamber and the bottom surface position of the foam chamber are both higher than the bottom surface position of the drainage chamber; the top connection position of the liquid inlet chamber 10 and the drainage chamber 20 is higher than the top connection position of the drainage chamber 20 and the foam chamber 30; and a siphon structure is provided between the drainage chamber 20 and the foam chamber 30.

[0095] In some embodiments, Figure 1 and Figure 2As shown, the foam generating device 1 comprises an outer shell, and a liquid inlet chamber 10, a liquid discharge chamber 20 and a foam chamber 30 are formed inside the outer shell. The liquid inlet chamber 10, the liquid discharge chamber 20 and the foam chamber 30 are open chambers with closed bottoms and open tops; and a top channel is defined between the outer shell and the tops of the liquid inlet chamber 10, the tops of the liquid discharge chamber 20 and the tops of the foam chamber 30;

[0096] The top channel enables the liquid inlet chamber 10 and the liquid discharge chamber 20 to communicate at the top, and enables the liquid discharge chamber 20 and the foam chamber 30 to communicate at the top.

[0097] In the embodiment of the present invention, by configuring the liquid inlet chamber 10, the liquid discharge chamber 20 and the foam chamber 30 as open chambers with closed bottoms and open tops, the foam generating device can maximize the effective volume of the liquid inlet chamber 10, the effective volume of the liquid discharge chamber 20, and the effective volume of the foaming chamber 30 when in use.

[0098] At the same time, through the top channel defined between the outer shell of the foam generating device 1 and the liquid inlet chamber 10, the liquid discharge chamber 20, and the foam chamber 30, the foam and / or liquid overflowing from the liquid inlet chamber 10 can only be discharged through the liquid discharge chamber 20 and the foaming chamber 30 in sequence, thereby preventing the foam overflowing from the liquid inlet chamber 10 from flowing to places other than the liquid discharge chamber 20 and the foaming chamber 30, thereby effectively improving the effect of the foam generating device 1 when in use.

[0099] In some embodiments, Figure 1 and Figure 2 As shown, the foam generating device 1 also includes:

[0100] The siphon device 50 is disposed between the drainage chamber 20 and the foam chamber 30 and is used to discharge the liquid in the drainage chamber 20 into the foam chamber 30 when the liquid level in the drainage chamber 20 reaches a preset liquid level.

[0101] In the embodiment of the present invention, a siphon device is provided between the drainage chamber 20 and the foaming chamber 30. When the liquid level in the drainage chamber 20 exceeds the highest point of the siphon channel, the liquid in the drainage chamber 20 is completely discharged into the foam chamber 30 under the action of the siphon principle, and the liquid in the foam chamber 30 can be discharged by supplying air and pressurizing the foam generating device 1.

[0102] In some embodiments, Figure 1 and Figure 2As shown, the volume of the liquid inlet chamber 10, the volume of the liquid discharge chamber 20 and the setting position of the siphon device are designed as follows: after all the liquid in the liquid inlet chamber 10 is discharged into the liquid discharge chamber 20, the liquid level position of the liquid discharge chamber 20 is higher than the liquid discharge chamber siphon fixed point height of the siphon device 50, and the suction end of the siphon device 50 located in the liquid discharge chamber 20 is arranged close to the bottom of the liquid discharge chamber 20, and the volume of the liquid discharge chamber 20 is less than or equal to the volume of the foam chamber 30 below the suction end of the siphon device 50, so that when the liquid discharge chamber 20 needs to be emptied, the liquid in the liquid discharge chamber 20 can be completely discharged into the foam chamber 30 through the siphon device 50.

[0103] In some embodiments, Figure 1 and Figure 2 As shown, the foam generating device also includes:

[0104] A spray water inlet pipe 100, on which a spray water inlet valve 1001 is provided, and a spray head 1002 is provided at the water outlet end of the spray water inlet pipe 100;

[0105] The shower head corresponds to the top opening position of the liquid inlet cavity 10 .

[0106] In this way, during the ventilation and foaming process of the foam generating device, the spray water inlet valve 1001 can be opened to allow the spray head 1002 to eject a high-speed water flow to impact the washing liquid in the liquid inlet chamber 10, thereby promoting foaming and increasing the amount of foam.

[0107] In some embodiments, Figure 1 and Figure 2 As shown, the laundry processing device comprises:

[0108] The detergent box 80 has one end connected to a main wash water inlet valve 801 and the other end connected to a clothes treatment drum 90 through a main wash water inlet pipe 802 for discharging the washing water mixed with detergent in the detergent box 80 into the clothes treatment drum 90 .

[0109] That is, when the laundry processing device in the embodiment of the present invention is taking in water for washing, the main water inlet pipeline is still connected to the detergent box, so that the detergent in the detergent box 80 can be brought into the laundry processing drum 90 synchronously when taking in water.

[0110] In some embodiments, Figure 1 and Figure 2 As shown, the liquid inlet pipe includes a first pipeline 300, a second pipeline 500 and a third pipeline 600. One end of the first pipeline 300 is connected to the laundry treatment tub, and the other end is connected to the water inlet end of the water pump 400. The drainage end of the water pump 400 is connected to the second pipeline 500 and the third pipeline 600.

[0111] Preferably, the drainage pipeline 300 connected to the water pump is at least partially a corrugated pipe section to absorb vibration and noise caused by drainage.

[0112] One of the second pipeline 500 and the third pipeline 600 is connected to the liquid inlet 101 of the foam generating device, and an emergency drain outlet 700 is provided on the drain pipe connected to the liquid inlet 101 .

[0113] In the embodiment of the present invention, the liquid inlet pipeline connected to the foam generating device 1 is arranged at the position of the emergency drain outlet 700 of the clothing processing equipment, so that the installation and removal of the drain pipe can be facilitated.

[0115] A heating tank 200 provided at the bottom of the laundry processing tub 90;

[0116] The liquid inlet end of the liquid inlet pipe is communicated with the heating tank 200 .

[0118] Furthermore, a second aspect of an embodiment of the present invention further provides a washing control method for a clothes processing device, which is applied to the clothes processing device provided in the first aspect above, wherein the clothes processing device has a washing program, and the washing control method includes:

[0119] Under the washing program, the air pump 60 is controlled to be periodically closed and opened according to a preset first cycle;

[0120] When the air pump 60 is controlled to be turned off, water enters the foam generating chamber, and when the air pump 60 is controlled to be turned on, water stops entering the foam generating chamber.

[0121] Preferably, the above-mentioned washing procedure is an ozone foam washing procedure.

[0122] In the embodiment of the present invention, by controlling the intermittent opening of the air pump 60 under the washing program, on the one hand, the automatic water inlet and automatic water stop effect of the foam generating device can be achieved, and on the other hand, the water inlet amount of the foam generating device 1 can be reasonably controlled, thereby ensuring the automatic water inlet and stop effect while improving the foaming effect of the foam generating device 1, thereby improving the washing effect of the clothing processing equipment on the clothing.

[0124] When the air pump 60 is turned on, the gas generator 70 is controlled to be turned on, and when the air pump 60 is turned off, the gas generator 70 is controlled to be turned off.

[0125] That is, when the foamer in the embodiment of the present invention is foaming the detergent, the sterilization gas generated by the gas generator is simultaneously introduced, so that the detergent foam and the sterilization gas are fully combined together and then discharged into the clothing processing drum 90 to act on the surface of the clothes, thereby improving the cleaning effect of the clothes while improving the sterilization effect of the clothes.

[0126] Further, in some embodiments, controlling the air pump 60 to be periodically turned off and on according to a preset first cycle includes:

[0131] Preferably, during the first time period when the air pump 600 is turned off, the amount of water entering the liquid inlet chamber 10 is equal to the volume of the liquid inlet chamber 100; in this way, the high-concentration washing liquid entering the liquid inlet chamber 10 during the first time period can completely discharge the low-concentration washing liquid remaining at the bottom of the liquid inlet chamber 10 after the last foaming is completed into the liquid discharge chamber 20, thereby improving the foaming effect of the washing liquid in the liquid inlet chamber 10.

[0132] Preferably, during the second time period when the air pump 600 is turned on, the amount of water consumed by the foamer 40 during the second time period is equal to the amount of water inlet into the liquid inlet chamber 10 during the first time period. In this way, the foamer 40 can completely foam the washing liquid in the liquid inlet chamber 10 during the second time period, thereby fully foaming the washing liquid in the liquid inlet chamber 10 during the second time period, and then maximally foaming the washing liquid in the laundry treatment drum 90 during the washing time under the washing program, thereby maximizing the washing effect on the laundry.
