DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0045] When currently used steam devices generate steam, they need to heat the liquid first. Steam will only be generated when the liquid temperature reaches a certain temperature. This cannot meet the normal care needs, resulting in a slow care process and poor results. In the embodiment of the present invention, gas is preferentially generated through the first gas generating chamber. Since the gas generating capacity of the first gas generator in the first gas generating chamber is greater than the gas generating capacity of the second gas generator in the second gas generating chamber, gas can be generated immediately when the liquid is injected into the first gas generating chamber. The gas generation speed is relatively fast. Therefore, when the user selects the clothing care program, on the one hand, the atomization effect of the washing machine can be seen immediately {the atomization effect can be seen from the glass window of the washing machine}, providing a user experience. On the other hand, within the unit care time, the time that the gas acts on the clothes is longer {because the gas generation speed is relatively fast}, so the care effect on the clothes can be improved within the unit care time.

[0046] The following is combined with Figure 1-5 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0047] Example

[0048] like Figures 1-4 As shown, in a first aspect of this embodiment, a gas generating assembly is provided for generating gas to care for a load in a washing machine. The gas generating assembly includes:

[0049] a first gas generating chamber, wherein a first gas generator is provided in the first gas generating chamber, and the first gas generator can generate gas from the liquid in the first gas generating chamber;

[0050] a second gas generating chamber, wherein a second gas generator is provided in the second gas generating chamber, and the second gas generator can generate gas from the liquid in the second gas generating chamber;

[0051] The gas generating assembly is designed as follows: when liquid is introduced into the gas generating assembly, the first gas generating chamber is introduced before the second gas generating chamber and the first gas generator is opened before the second gas generator, wherein the gas generating capacity of the first gas generator is greater than the gas generating capacity of the second gas generator, wherein the gas generating capacity includes the gas generation amount and / or the gas generation speed.

[0052] In the embodiment of the present invention, gas is preferentially generated through the first gas generating chamber. Since the gas generating capacity of the first gas generator in the first gas generating chamber is greater than the gas generating capacity of the second gas generator in the second gas generating chamber, the first gas generating chamber can generate gas immediately when liquid is injected. The speed of gas generation is relatively fast. Therefore, when the user selects the clothing care program, on the one hand, the atomization effect of the washing machine can be seen immediately {the atomization effect can be seen from the glass window of the washing machine}, providing a user experience. On the other hand, within the unit care time, the time that the gas acts on the clothes is longer {because the gas generation speed is relatively fast}, so the care effect on the clothes can be improved within the unit care time. Specifically;

[0053] The first gas generating chamber includes an atomizing chamber, and the first gas generator includes an atomizer 2 provided in the atomizing chamber, and the atomizer 2 is used to atomize the liquid in the atomizing chamber to generate atomized gas;

[0054] The second gas generating chamber includes a steam generating chamber 3 , and the second gas generator includes a heater 4 provided in the steam generating chamber 3 . The heater 4 is used to heat the liquid in the steam generating chamber 3 to generate evaporated gas.

[0055] In the embodiment of the present invention, gas is preferentially generated through the atomizer. Since the atomizer does not need to heat the liquid, it generates gas at a faster speed. Therefore, when the user selects the clothing care program, the user can see the atomization effect of the washing machine at the first time {the atomization effect can be seen from the glass window of the washing machine}, thereby improving the user experience on the one hand, and on the other hand, improving the clothing care effect within the unit care time.

[0056] Specifically, such as Figure 4 and Figure 5 As shown, the atomizing chamber has a first liquid inlet 11 and a first liquid outlet 12, and the steam generating chamber 3 has a second liquid inlet 31;

[0057] The first liquid inlet 11, the first liquid discharge port 12 and the second liquid inlet 31 are designed as follows: when the liquid entering the atomization chamber from the first liquid inlet 11 exceeds the bottom position of the first liquid discharge port 12, the liquid exceeding the bottom position of the first liquid discharge port 12 can be discharged into the second liquid inlet 31 of the steam generating chamber 3 through the first liquid discharge port 12 to enter the steam generating chamber 3.

[0058] In the embodiment of the present invention, when the liquid level in the atomizing chamber reaches the position of the first liquid drain port 12, it can be discharged into the second liquid inlet 31 of the steam generating chamber 3 through the first liquid drain port 12, and the excess liquid in the atomizing chamber is discharged into the steam generating chamber 3 through the second liquid inlet 31. That is, through the above structure in the embodiment of the present invention, the gas generating component in the embodiment of the present invention only needs to be provided with one liquid inlet pipe to meet the liquid inlet requirements of the two chambers, without having to provide multiple liquid inlet pipes to respectively perform liquid inlet processing on the atomizing chamber and the steam generating chamber 3, thereby reducing production costs.

[0059] In any of the above embodiments, the atomizing chamber mentioned above has an atomizing liquid level, and the atomizer 2 can be controlled to open when the liquid level in the atomizing chamber reaches the atomizing liquid level, wherein;

[0060] The bottom of the first liquid discharge port 12 is set to be flush with the atomized liquid level, or;

[0061] The bottom of the first liquid discharge port 12 is arranged close to the atomized liquid level relative to the bottom of the first liquid inlet 11 .

[0062] Preferably, the bottom of the first liquid discharge port 12 is set to be flush with the atomized liquid level.

[0063] That is, in the embodiment of the present invention, when the liquid level in the atomization chamber reaches the atomization liquid level, the atomization function can be turned on in time to produce the atomization effect, and at the same time, the excess liquid is discharged into the steam generating chamber 3 in time to provide a heating medium for the heater, thereby producing the atomization effect to the greatest extent during the atomization care stage.

[0064] In any of the above embodiments, the steam generating chamber 3 mentioned above has a heating liquid level, and the heater 4 can be controlled to turn on when the liquid level in the steam generating chamber 3 reaches the heating liquid level;

[0065] The top of the heater 4 is located below the heating liquid level.

[0066] In the embodiment of the present invention, by controlling the heating liquid level to be set above the heater 4, it is possible to avoid the liquid level in the steam generating chamber 3 being too low to cause the heater 4 to dry out, thereby effectively protecting the heater 4.

[0067] Specifically, the atomizer 2 is connected to a first circuit, and the first circuit is used to turn on the atomizer 2 when it is turned on;

[0068] The heater 4 is connected to a second circuit, which is used to turn on the heater 4 when it is turned on.

[0069] The first circuit is conducted when the liquid level in the atomizing chamber reaches the atomizing liquid level, and the second circuit is conducted when the liquid level in the steam generating chamber 3 reaches the heating liquid level.

[0070] In the embodiment of the present invention, the atomizer 3 and heater 4 are turned on and off according to the changes in the liquid level in the atomizing chamber and the steam generating chamber 3. This can prevent the occurrence of dry burning. In other words, atomized gas and / or steam will only be generated when there is liquid in the chamber (the atomizing chamber and the steam generating chamber 3) and the liquid level reaches the target level.

[0071] More specifically, Figure 3-Figure 5 As shown, the gas generating assembly includes a first probe 5, a second probe 6 and a third probe 7;

[0072] The first probe 5 and the second probe 6 are arranged in the atomizing chamber and connected in series in the first circuit, wherein the bottoms of the first probe 5 and the second probe 6 are arranged close to or flush with the atomizing liquid level in the atomizing chamber;

[0073] The third probe 7 is disposed in the steam generating chamber 3 and is connected in series with the first probe 5 and / or the second probe 6 in the second circuit, wherein the bottom of the third probe 7 is located at the heating liquid level in the steam generating chamber 3 .

[0074] In the embodiment of the present invention, a probe is provided to control the on / off switching of the atomizer 2 and heater 4. The probe can precisely control the conduction and disconnection of the circuit when the liquid level in the atomizing chamber or the steam generating chamber 3 changes, thereby accurately controlling the on / off switching of the atomizer 2 and heater 4 and preventing dry-burning of the atomizer 2 and heater 4. Furthermore, since the atomizing chamber and the steam generating chamber 3 are connected, there is no need to install two probes in the steam generating chamber 3 to detect the liquid level. Only one probe is required to control the circuit and thus the on / off switching of the heater.

[0075] Furthermore, the bottom position of the third probe 7 arranged in the steam generating chamber 3 is set lower than the bottom position of the first probe 5, so that the liquid can be heated as quickly as possible, thereby shortening the steam generation time and further shortening the clothing care time {because the heater 4 takes a long time to heat the liquid to gas, the heater 4 is made to work as much as possible while ensuring that the heater 4 does not dry burn}.

[0076] In any of the above embodiments, Figure 1-Figure 5 As shown, the gas generating assembly includes an atomizing box 1a and a steam generating box 3a which are independent of each other. An atomizing chamber is formed inside the atomizing box 1a, and a steam generating chamber 3 is formed inside the steam generating box 3a.

[0077] The atomizing box 1 a is provided with an atomizing gas transmission pipe 13 communicating with the atomizing chamber, and the steam generating box 3 a is provided with a evaporation gas transmission pipe 32 communicating with the steam generating chamber 3 .

[0078] In the embodiment of the present invention, by providing gas transmission tubes (atomizing gas transmission tube 13 and evaporating gas transmission tube 32) in the atomizing box 1a and the steam generating box 3a, respectively, this prevents the evaporating gases in the two boxes (atomizing box 1a and steam generating box 3a) from sharing the same chamber. Taking a conventional washing machine as an example, when the washing machine is filled with water, the atomizing gas temperature is relatively low, while the evaporating gas temperature is relatively high, as the water inlet is typically cold. If these two gases at different temperatures were placed in the same chamber, the small space and large temperature difference could result in a large amount of condensed water, resulting in a low amount of gas (atomizing gas and evaporating gas) available for clothing care, thus affecting the clothing care effect. In contrast, in the embodiment of the present invention, the two gases are delivered to the washing drum via two separate gas transmission tubes. Due to the larger volume of the washing drum and the reduced temperature difference between the two gases during gas transportation, condensation does not occur in the washing drum due to the large temperature difference. Consequently, the technical effect achieved is that the steam supply for clothing care is guaranteed while condensation is avoided, thereby improving the clothing care effect.

[0079] Furthermore, a drain pipe 8 is provided between the atomizing box 1a and the steam generating box 3a for connecting the atomizing chamber and the steam generating chamber, and is used to discharge excess liquid into the steam generating chamber 3 when the liquid level in the atomizing chamber exceeds the atomizing liquid level;

[0080] The liquid inlet position of the liquid discharge pipe 8 is lower than the liquid inlet position of the atomization chamber.

[0081] A second aspect of this embodiment provides a washing machine, which includes the above-mentioned gas generating assembly.

[0082] Specifically, the above-mentioned washing machine is a twin-drum washing machine, which includes a first laundry processing drum and a second laundry processing drum, the first laundry processing drum is connected to a first air duct, and the second laundry processing drum is connected to a second air duct;

[0083] The first clothes processing tub is in communication with the atomizing gas transmission pipe through the first air duct, and the second clothes processing tub is in communication with the evaporating gas transmission pipe through the second air duct.

[0084] In the embodiment of the present invention, two air pipes are connected to different washing tubs, so when caring for clothes, different washing tubs can be selected according to different types of clothes.

[0085] For example, when caring for baby clothes, the baby clothes can be placed in the first clothes treatment tub. Since the first clothes treatment tub can independently discharge atomized gas with a lower temperature, the care effect for the baby clothes can be improved.

[0086] For example, when caring for pure cashmere, wool, pure leather, fur and leather, down jackets or suits, the clothes made of the above materials can be placed in the second clothes treatment drum. Since the second clothes treatment drum can discharge the higher temperature evaporative gas separately, the care effect of the clothes made of the above materials can be improved.

[0087] More specifically, a bypass pipe is provided between the atomizing gas transmission pipe and the boil-off gas transmission pipe, one end of the bypass pipe is connected to the atomizing gas transmission pipe, and the other end is connected to the boil-off gas transmission pipe. A bypass pipe valve is provided on the bypass pipe, and the bypass pipe valve can be controlled to open or close; or;

[0088] A bypass air duct is provided between the first air duct and the second air duct, one end of the bypass air duct is connected to the first air duct, and the other end is connected to the second air duct. A bypass air duct valve is provided on the bypass air duct, and the bypass air duct valve can be controlled to open or close.

[0089] The bypass pipe valve can be controlled to open part or all of the bypass pipe to control the mixing degree of two gases with different temperatures, or;

[0090] The bypass air duct valve can be controlled to open part or all of the bypass air duct to control the mixing degree of the two gases with different temperatures.

[0091] In the embodiment of the present invention, a bypass pipe is provided to mix the gases of different temperatures in the two gas transmission pipes, and by controlling the bypass valve, the temperature of the mixed gas can be controlled, thereby enabling further targeted care of clothes according to the characteristics of different types of clothes.

[0092] The following combination Figure 6 The working principle of the washing machine in the embodiment of the present invention when executing the care program is described below:

[0093] When the washing machine is performing clothing care, the water inlet switch is first turned on, and water enters the atomizer box 1a from the first liquid inlet 11. When the liquid level in the atomizer chamber inside the atomizer box 1a rises to the atomization liquid level, the first circuit for turning on the atomizer 2 is turned on, and the atomizer 2 starts working to atomize the water. The atomized atomized gas is transported to the clothing treatment drum through the atomizing gas transmission pipe.

[0094] When the liquid level in the atomizing chamber exceeds the atomizing level, the water exceeding the atomizing level enters the steam generating chamber 3 of the steam generating box 3a through the first liquid drain port 12. When the liquid level in the steam generating chamber 3 rises to the heating level, the second circuit for turning on the heater 4 is conducted, and the heater 4 starts to operate, heating the water to generate steam, which is then transported to the laundry treatment tub through the evaporated gas transmission pipe 32.

[0095] Other embodiments of the present invention will readily occur to those skilled in the art after considering the specification and practicing the embodiments disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow from the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
