DETAILED DESCRIPTION

[0028] ​The exemplary embodiments will be described in detail below with reference to the drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent the same or similar elements. The following exemplary embodiments described are not meant to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0029] As Figures 1 to 5 shown, the exemplary embodiments of the present disclosure provide a microbubble generating device 100, which can be optionally applied to a water inlet system, and further optionally applied to a water inlet system of a laundry treating apparatus. The laundry treating system herein includes, but is not limited to, a single drum washing machine, a single drum dryer, a single drum washer-dryer, a double drum washing machine, a double drum dryer, a double drum washer-dryer, etc.

[0030] During the process of laundry treating, there is usually a need to add a detergent such as laundry liquid or laundry powder. The conventional apparatus needs to manually add the detergent, and the degree of automation is low. With the development of technology, some laundry treating apparatuses capable of automatically adding the detergent are gradually welcomed. The way of automatically adding the detergent is to use the water to flush into a laundry dosing box, and to mix the water and the detergent in the laundry dosing box, and to flush the mixed water and detergent into a laundry drum by means of the backwash force of the water or by means of a pump. However, the untreated water has limited ability to dissolve the detergent, mainly reflected in slow dissolution speed and insufficient dissolution, which further affects the amount of detergent entering the laundry drum, and the detergent that is not dissolved in time is also wasted.

[0031] Considering the above technical problems, as Figure 1 shown, the microbubble generating device 100 provided by the present disclosure includes a heating device 2 and a microbubble generating device 3, wherein the heating device 2 is adapted to heat the water, and the microbubble generating device 3 is adapted to generate bubbles in the water. The water herein refers to the water flow from the water inlet valve 200 to the laundry drum in the water inlet system, and the water flows through the microbubble generating device 100 and the laundry dosing box 300 during the process of the water flowing to the laundry drum. For example, before the water enters the laundry drum, the water is heated by the heating device 2 and generates bubbles by the microbubble generating device 3, and then flows into the laundry dosing box 300 to dissolve the detergent. The heating device 2 can be, for example, a heating coil or a heating wire. The microbubble generating device 3 can include, for example, a Venturi tube and / or a bubble stone, that is, the microbubble generating device 3 can be a Venturi tube, or a bubble stone, or both a Venturi tube and a bubble stone, which will be described in more detail later.

[0032] The microbubble generating device 3 can make the water inlet generate abundant bubbles, which is conducive to improving the dissolution speed of the detergent and making the detergent fully dissolved. For example, the water inlet with bubbles can make the detergent more easily dissolved in the manner of increasing the contact area, reducing the surface tension and generating similar stirring effect when the bubbles break. And heating the water inlet by the heating device 2 to improve the temperature of the water inlet is also conducive to making the detergent quickly and fully dissolved. Heating the water inlet can also improve the chemical reaction rate of the detergent and the activity of the enzyme, so that the washing effect is better, and since the detergent can be quickly and fully dissolved, the waste of the detergent can also be avoided, thereby saving the amount of the detergent. That is, the microbubble generating device 100 provided by the present disclosure can utilize the double quick dissolution scheme formed by the two ways of the heated water inlet and the abundant bubbles to improve the dissolution speed of the detergent and make the dissolution of the detergent more sufficient.

[0033] In some embodiments, the heating device 2 and the microbubble generating device 3 can be arranged in the water inlet pipe, that is, the water inlet can be directly heated by the heating device 2 and generate bubbles under the action of the microbubble generating device 3 during the flowing process in the water inlet pipe. In other embodiments, as shown in FIG. 1, the microbubble generating device 100 can also include a shell 1, and the shell 1 is respectively provided with a first water inlet 113 and a water outlet 123. The heating device 2 and the microbubble generating device 3 are both accommodated in the interior of the shell 1. Figure 1 By arranging the shell 1, on the one hand, the heating device 2 and the microbubble generating device 3 in the interior can be protected, and on the other hand, as in the first embodiment, the heating device 2 and the microbubble generating device 3 are directly arranged in the water inlet pipe, and since the water flow speed in the water inlet pipe is fast, it can cause insufficient heating and bubble generation. By making the water inlet enter the shell 1 first, the water inlet can be fully heated and bubbles can be generated, thereby further improving the dissolution speed of the detergent.

[0034] In addition, the heating device 2 and the microbubble generating device 3 can be arranged in one chamber or two chambers, which is not limited in the present disclosure. In the embodiment shown in FIG. 1, the heating device 2 and the microbubble generating device 3 are arranged in two chambers, that is, the heating device 2 is arranged in the first chamber 11, and the microbubble generating device 3 is arranged in the second chamber 12. Figure 1In the shown embodiment, the housing 1 is provided with a first chamber 11 and a second chamber 12 in communication, one of the heating device 2 and the microbubble generating device 3 is arranged in the first chamber 11, and the other is arranged in the second chamber 12. The water inlet flows into the housing 1 from the first water inlet 113, is heated by the heating device 2 and generates bubbles by the microbubble generating device 3, and then flows into the washing detergent box 300 through the water outlet 123 to dissolve the washing detergent. That is, the heating and bubble generation can be made as two independent processes, which is particularly meaningful when the microbubble generating device 3 includes a Venturi tube as will be described later, in which the water inlet generates water in the Venturi tube, and it is difficult to directly heat the water in the tube. The present disclosure makes the heating and bubble generation as two independent processes, so as to ensure the effect of water heating.

[0035] In some embodiments, the first water inlet is in communication with the first chamber, the water outlet 123 is in communication with the second chamber 12, the heating device 2 is arranged in the first chamber 11, and the microbubble generating device 3 is arranged in the second chamber 12, that is, the water inlet flows into the housing 1 from the first water inlet 113, is first heated by the heating device 2, and then enters the second chamber 12, and generates bubbles under the action of the microbubble generating device 3 in the second chamber 12. This flow path of heating first and then generating bubbles helps to avoid the risk of defoaming of the generated bubbles under the action of high temperature, so that the number of generated bubbles is more abundant.

[0036] In some embodiments, as shown in Figure 2 and Figure 3 The second chamber 12 includes a first microbubble generating chamber 121 and a second microbubble generating chamber 122 in communication, and the microbubble generating device 3 includes a first microbubble generating device 31 arranged in the first microbubble generating chamber 121 and a second microbubble generating device 32 arranged in the second microbubble generating chamber 122. Taking the above-mentioned example that the heating device 2 is arranged in the first chamber 11 and the microbubble generating device 3 is arranged in the second chamber 12, the first chamber 11 is in communication with the first microbubble generating chamber 121, and the water outlet 123 is arranged in the second microbubble generating chamber 122.

[0037] Compared with the embodiment with only one level of microbubble generation, in this embodiment, the process includes two levels of microbubble generation, which makes the number of bubbles generated by the water inlet more abundant, so as to more facilitate to improve the dissolution speed of the washing detergent. It should be understood that according to actual needs, a larger number of microbubble generating chambers can also be arranged, and the present disclosure does not limit this. In addition, the same type of microbubble generating device 31 can be arranged in different microbubble generating chambers, or different types of microbubble generating device 31 can be arranged, which will be described in more detail later.

[0038] The first microbubble generator 31 and the second microbubble generator 32 can be configured to generate gas bubbles of different diameters. For example, the first microbubble generator 31 can be configured to generate millimeter-sized gas bubbles, and the second microbubble generator 32 can be configured to generate micron-sized gas bubbles. This allows the microbubble generating device 100 to generate a larger number of gas bubbles of different sizes, which can provide different contact areas with the detergent and different convection speeds and different turbulent flows due to different rising speeds in water, thereby further improving the dissolution speed of the detergent. In the above example of two-stage microbubble generation, the first microbubble generator 31 and the second microbubble generator 32 can both be Venturi tubes, or both be bubble stones, or one be a Venturi tube and the other be a bubble stone.

[0039] In some embodiments, as shown in FIG. 1, the first microbubble generator 31 includes a Venturi tube. The water inlet 311 of the Venturi tube is in communication with the first chamber 11, the water outlet 312 of the Venturi tube is inside the first microbubble generating cavity 121, and the air inlet 313 of the Venturi tube extends outside the shell 1. The shell 1 can be provided with a cover air inlet 1121 for the air inlet 313 of the Venturi tube to extend out. Specifically, the water inlet 311 of the Venturi tube is in communication with the first chamber water outlet 1141, and the water mixed with the gas bubbles flows into the first microbubble generating cavity 121, and then flows into the second microbubble generating cavity 122 from the second chamber water outlet 1142. Figures 2 to 4

[0040] The Venturi tube utilizes the Venturi effect to draw in and mix gas to form bubbles. When the fluid passes through the narrow throat 314 of the Venturi tube, the cross-sectional area decreases, the flow rate increases, and the pressure decreases according to Bernoulli's theorem, thereby allowing the gas to be drawn in and mixed with the high-speed flowing liquid to form bubbles. The bubbles then flow out of the water outlet 312 of the Venturi tube along with the liquid. Since the Venturi tube can draw in gas using its own structure, it does not require additional air pumps or other devices, and the structure is simpler.

[0041] In other embodiments, as shown in FIG. 2, the second microbubble generator 32 includes a bubble stone. The bubble stone, also known as an air stone or an aeration stone, is typically made of a porous material such as ceramic, glass, or silica gel. The porous material has many tiny channels inside. When gas passes through the bubble stone, the gas is divided into many tiny bubbles, which enter the water through the channels of the bubble stone. The bubble stone is relatively simple and reliable in generating bubbles, and the cost is relatively low. Figure 2 Figure 3

[0042] ​​​According to some embodiments provided by the present disclosure, as Figure 5 As shown in the figure, the shell 1 is also provided with a second water inlet 124 which is in communication with the second chamber 12. Among them, the first water inlet 113 is adapted to be in communication with the first water inlet valve 210 of the water inlet system through the first water inlet pipe 400, and the second water inlet 124 is adapted to be in communication with the second water inlet valve 220 of the water inlet system through the second water inlet pipe 600. By selectively controlling the opening of the first water inlet valve 210 and the second water inlet valve 220, two water inlet paths can be realized. Taking the above example in which the heating device 2 is arranged in the first chamber 11 and the microbubble generating device 3 is arranged in the second chamber 12 as an example, one of the paths is that the water first flows into the second chamber 12 after being heated by the heating device 2 in the first chamber 11, and then generates bubbles in the second chamber 12 under the action of the microbubble generating device 3, and then flows into the laundry dosing box 300, while in the other path, the first water inlet valve 210 can be closed, so that the water directly enters the second chamber 12. At this time, compared with the first path, the water can not be heated. In this way, the user can choose whether to heat the water before generating bubbles according to needs.

[0043] As shown in the figure, Figure 3 In the microbubble generating device 100 provided by the present disclosure, the shell 1 can be configured as a detachable structure. Specifically, the shell can include a main body 111 having an opening at the top and a cover body 112 arranged on the main body 111, wherein the main body 111 is internally provided with a plurality of partitions 114 for separating the main body 111 into a first chamber 11 and a second chamber 12. The first chamber outlet 1141 and the second chamber outlet 1142 are both arranged on the partition 114. The cover body air inlet 1121, from which the air inlet 313 of the Venturi tube extends, is arranged on the cover body 112. By configuring the shell 1 to include the main body 111 and the cover body 112 in a split structure, it is convenient to replace and maintain the devices inside the main body 111, such as the heating device 2, the Venturi tube and the bubble stone.

[0044] According to the second aspect of the embodiments of the present disclosure, as Figure 5 As shown in the figure, a water inlet system is also provided, which includes the microbubble generating device 100 of any one of the above and has all the beneficial effects thereof, which will not be repeated here.

[0045] The water inlet system provided by the present disclosure includes a water inlet valve 200 and a laundry dosing box 300, and the microbubble generating device 100 is arranged between the water inlet valve 200 and the laundry dosing box 300. After the water inlet valve 200 is opened, the water can enter the microbubble generating device 100, be heated and generate bubbles, and then flow into the laundry dosing box 300 and mix with the detergent. Alternatively, the microbubble generating device 100 can also be arranged downstream of the laundry dosing box 300, so as to directly heat and generate bubbles for the water mixed with the detergent.

[0046] The microbubble generating device 100 provided by the present disclosure can be provided with only the first water inlet 113 in the first chamber 11, or can be provided with the second water inlet 124 in the second chamber 12 on the basis of the first water inlet 113. In the embodiment in which the first water inlet 113 is provided, the path is that the water first flows into the second chamber 12 after being heated by the heating device 2 in the first chamber 11, and then generates bubbles in the second chamber 12 under the action of the microbubble generating device 3, and then flows into the laundry feeding box 300.

[0047] In the embodiment in which the second water inlet 124 is further provided in the second chamber 12, the water inlet valve 200 can include a first water inlet valve 210 and a second water inlet valve 220, the first water inlet valve 210 being in communication with the first water inlet 113 through the first water inlet pipe 400, and the second water inlet valve 220 being in communication with the second water inlet 124 through the second water inlet pipe 600. By selectively controlling the opening of the first water inlet valve 210 and the second water inlet valve 220, two water inlet paths can be achieved. Taking the above-mentioned embodiment in which the heating device 2 is provided in the first chamber 11 and the microbubble generating device 3 is provided in the second chamber 12 as an example, one of the paths is that the water first flows into the second chamber 12 after being heated by the heating device 2 in the first chamber 11, and then generates bubbles in the second chamber 12 under the action of the microbubble generating device 3, and then flows into the laundry feeding box 300, and in the other path, the first water inlet valve 210 can be closed, so that the water directly enters the second chamber 12, and in this case, the water can not be heated compared with the first path. In this way, the user can choose whether to heat the water before generating bubbles according to the needs.

[0048] According to the third aspect of the embodiments of the present disclosure, a laundry washing apparatus is also provided, which includes the water inlet system of any one of the above and has all the beneficial effects thereof.
