Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment, and in particular to a foam generating device, a dispensing component, and clothing processing equipment. Background Technology

[0002] Current garment processing equipment typically involves directly adding detergent or other washing agents into the garment processing chamber or adding them to a dispensing unit and then rinsing them off with tap water. This method fails to ensure the detergent fully dissolves and foams, resulting in poor washing performance and negatively impacting the user experience. Related technologies often utilize structures like venturi tubes to generate foam; however, the dimensions of these structures can affect foam formation, necessitating the design of an appropriate size range. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide a foam generating device. The foam generating device according to the invention defines a ratio range between the diameter of the inlet and the diameter of the narrowed section, ensuring foaming efficiency while also considering the cost of the detergent solution.

[0004] The present invention also proposes a dispensing component including the above-described foam generating device.

[0005] The present invention also proposes a garment processing device including the above-described dispensing components.

[0006] The foam generating device according to the present invention includes a narrowed section, on which a liquid inlet is provided. The diameter of the narrowed section is d1, and the diameter of the liquid inlet is d2, and satisfies: 0.4≤d2 / d1≤0.45.

[0007] When d2 / d1 < 0.4, the diameter of the inlet is smaller than the diameter of the narrowing section. In this case, less detergent enters the main flow path through the inlet, resulting in insufficient detergent in the main flow path, reduced foam generation, and consequently, decreased washing effect. When d2 / d1 > 0.45, the diameter of the inlet is larger than the diameter of the narrowing section. In this case, more detergent enters the main flow path through the inlet, resulting in excessive detergent in the main flow path. Due to the limited size of the main flow path, this excessive detergent cannot foam in time before exiting the foam generating device, thus reducing the washing effect and increasing costs. Therefore, the diameter of the inlet and the diameter of the narrowing section should be within a suitable range. For example, d2 / d1 is preferably 0.43. When d2 / d1 = 0.43, the foaming effect is better than other values.

[0008] According to one embodiment of the present invention, the foam generating device includes a first section and a second section, one end of the first section being connected to the inlet of the foam generating device; the second section is configured as the narrowed section, one end of the second section being connected to the other end of the first section, and the liquid inlet is provided on the second section; wherein, the diameter of the second section is smaller than the diameter of the first section.

[0009] According to one embodiment of the present invention, one end of the third segment is connected to the other end of the second segment, the other end of the third segment is connected to the outlet of the foam generating device, and the diameter of the third segment is larger than the diameter of the second segment.

[0010] According to one embodiment of the present invention, an air intake port communicating with external air is formed on the reduced diameter section, and the air intake port is at least partially opposite to the liquid inlet in the radial direction.

[0011] According to one embodiment of the present invention, 2.5mm≤d1≤3.5mm.

[0012] According to one embodiment of the present invention, 1mm≤d2≤1.5mm.

[0013] According to one embodiment of the present invention, the diameter of the second segment is d1, the diameter of the air inlet is d3, and the following condition is satisfied: 0.45≤d3 / d1≤0.55.

[0014] According to one embodiment of the present invention, 1.2mm≤d3≤2mm.

[0015] According to one embodiment of the present invention, the diameter of the second segment is d1, and the diameters of the first segment and the third segment are d4, and satisfy 0.35≤d1 / d4≤0.45.

[0016] The following is a brief description of the delivery component according to the present invention.

[0017] The dispensing assembly according to the present invention includes a foam generating device and a foam dispensing device as described in the above embodiments. The foam dispensing device is connected to the foam generating device and is adapted to dispense foam generated by the foam generating device. The foam generating device is primarily used to generate foam; while the foam dispensing device is primarily used to dispense the foam mixture, although foam can also be generated within the foam dispensing device. Through the cooperation between the foam generating device and the foam dispensing device, the foam dispensing assembly allows the detergent to be foamed multiple times before being used for washing. The foam-containing detergent mixture increases the contact area with the items to be washed, resulting in better washing performance and improved cleaning efficiency.

[0018] The garment processing device according to the present invention is briefly described below.

[0019] The garment processing device according to the present invention includes the dispensing component in the above embodiments. Since the garment processing device according to the present invention is provided with the dispensing component in the above embodiments, the dispensing component can be assembled into the workbench of the garment processing device. When the dispensing component is assembled, the cleaning effect of the garment processing device can be improved, thereby improving the user experience.

[0020] In summary, the foam generating device is configured with a first section, a second section, and a third section connected in sequence. The second section is equipped with a liquid inlet and an air intake. The dimensions or proportional relationship between the dimensions of the first, second, and third sections, the liquid inlet, and the air intake are limited. Through reasonable planning and design, the efficiency of the detergent entering through the liquid inlet, the efficiency of the air entering through the air intake, and the combined flow rate of the mixed liquid in the second and third sections are kept in a relatively balanced state. This can improve the foaming efficiency and foaming quality of the foam generating device, thereby improving the cleaning effect of the foam generating device.

[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] Current garment processing equipment typically involves directly adding detergent or other washing agents into the garment processing chamber or adding them to a dispensing unit and then rinsing them off with tap water. This method fails to ensure the detergent fully dissolves and foams, resulting in poor washing performance and negatively impacting the user experience. Related technologies often utilize structures like venturi tubes to generate foam; however, the dimensions of these structures can affect foam formation, necessitating the design of an appropriate size range.

[0033] The following is for reference. Figures 1-3 A foam generating apparatus according to an embodiment of the present invention is described.

[0034] The foam generating device 120 according to the present invention includes a narrowed section, on which a liquid inlet 121 is provided. The diameter of the narrowed section is d1, and the diameter of the liquid inlet 121 is d2, and satisfies: 0.4≤d2 / d1≤0.45.

[0035] Since the inlet 121 is located in the narrowing section, the dimensional relationship between the inlet 121 and the narrowing section affects foam generation. Specifically, if the diameter of the narrowing section is d1 and the diameter of the inlet 121 is d2, then the following condition must be met: 0.4 ≤ d2 / d1 ≤ 0.45. When d2 / d1 < 0.4, the diameter of the inlet 121 is smaller than the diameter of the narrowing section. In this case, less detergent enters the main flow path through the inlet 121, resulting in insufficient detergent in the main flow path, reducing foam generation, and consequently decreasing the washing effect. When d2 / d1 > 0.45, the diameter of the inlet 121 is larger than the diameter of the narrowing section. In this case, more detergent enters the main flow path through the inlet 121, resulting in excessive detergent in the main flow path. Because the main flow path is limited in size, this excessive detergent cannot foam in time before exiting the foam generating device 120, thus reducing the washing effect. Therefore, the diameter of the liquid inlet 121 and the diameter of the narrowing section should be within a suitable range. For example, d2 / d1 is preferably 0.43. When d2 / d1 = 0.43, the foaming effect is better than other values.

[0036] In some embodiments, the cleaning substance may be a detergent, fabric softener, bactericide, or other functional preparations for cleaning.

[0037] According to one embodiment of the present invention, the foam generating device 120 includes a first section 1201 and a second section 1202. One end of the first section 1201 is connected to the inlet of the foam generating device 120. The second section 1202 is configured as a narrowed section, and one end of the second section 1202 is connected to the other end of the first section 1201. An inlet 121 is provided on the second section 1202. The diameter of the second section 1202 is smaller than the diameter of the first section 1201.

[0038] Specifically, the foam generating device 120 is provided with a first section 1201 and a second section 1202 connected in sequence. The first section 1201 is connected to the inlet of the foam generating device 120; the second section 1202 connects the first section 1201 to the outlet of the foam generating device 120. Water can enter through the inlet of the foam generating device 120 and flow through the first section 1201 and the second section 1202 in sequence before flowing out through the outlet of the foam generating device 120. During this process, the detergent can enter the second section 1202 through the liquid inlet 121 on the second section 1202. The detergent and water mix in the second section 1202 to generate foam. The diameter of the second section 1202 is smaller than that of the first section 1201 and the third section 1203. Therefore, the flow rate in the second section 1202 is high, which can accelerate the mixing of the detergent with water. At this time, the mixture can generate a large amount of foam in the second section 1202, which improves the dissolution efficiency of the detergent. The foam-containing mixture flows out from the third section 1203 to clean the items to be washed, resulting in a better cleaning effect.

[0039] According to one embodiment of the present invention, the foam generating device 120 further includes a third section 1203, one end of the third section 1203 being connected to the other end of the second section 1202, and the other end of the third section 1203 being connected to the outlet of the foam generating device 120. The foam mixture flowing out of the second section 1202 flows out of the outlet of the foam generating device 120 after passing through the third section 1203. In the third section 1203, since the diameter of the third section 1203 is larger than the diameter of the second section 1202, the flow rate of the mixture in the third section 1203 is relatively slow, and the foam can be formed and stabilized in the third section 1203, reducing the proportion of foam breakage, thereby ensuring the cleaning effect of the foam generating device 120.

[0040] According to one embodiment of the present invention, an air intake 122 communicating with external air is formed on the reduced diameter section, and the air intake 122 is at least partially opposite to the liquid inlet 121 in the radial direction.

[0041] Specifically, an air intake 122 is formed on the narrowed section. When the foam generating device 120 is in use, the detergent and water flow enter the narrowed section through the liquid inlet 121 and the foam generating device 120 inlet, respectively, and mix within the narrowed section. At this time, external air can enter the narrowed section through the air intake 122. When the detergent and water flow foam within the foam generating device 120, the introduction of air increases the amount of foam, causing the foam generating device 120 to produce more foam, thereby improving the cleaning effect of the second water path. In addition, the air entering the narrowed section can also remain inside the foam, improving the stability of the foam, increasing the foam retention time, and further improving the washing effect.

[0042] During processing, the air intake 122 and the liquid inlet 121 can be at least partially aligned. Since the air intake 122 and the liquid inlet are at least partially aligned radially in the narrowing section, while the washing material flows through the liquid inlet into the main flow path, external air can directly enter the main flow path through the air intake 122, ensuring that the air and the mixture are fully contacted and mixed in the main flow path, thereby generating more and more stable foam.

[0043] According to one embodiment of the present invention, 2.5mm ≤ d1 ≤ 3.5mm. Since the size of d1 affects the flow rate of the detergent and water within the narrowed section, d1 needs to be maintained within a suitable range. Specifically, when d1 < 2.5mm, the diameter of the narrowed section is too small. In this case, the flow rate of the detergent and water within the narrowed section is too fast, making it difficult for the detergent and water to mix fully. This results in less foam generated by the foam generating device 120, leading to a reduction in the cleaning effect of the foam generating device 120. When d1 > 3.5mm, the diameter of the inlet 121 is too large. In this case, the flow rate of the detergent and water within the narrowed section is too slow. The fully mixed liquid, due to its low flow rate and low impact force, also produces relatively little foam. Therefore, 2.5mm ≤ d1 ≤ 3.5mm is a suitable range, and within this range, d1 is preferably 3mm.

[0044] According to one embodiment of the present invention, 1mm ≤ d2 ≤ 1.5mm. Since the size of d2 affects the entry of the detergent into the narrowing section, d2 needs to be maintained within a suitable range. Specifically, when d2 < 1mm, the diameter of the inlet 121 is too small. In this case, the rate at which the detergent enters the narrowing section is low, resulting in less foam generated by the foam generating device 120, which reduces the cleaning effect of the foam generating device 120. When d2 > 1.5mm, the diameter of the inlet 121 is too large. In this case, the efficiency of the detergent entering the narrowing section is too fast, resulting in too much detergent entering the foam generating device 120, which increases the waste of detergent and raises costs. Therefore, 1mm ≤ d2 ≤ 1.5mm is a suitable range, and within this range, d2 can preferably be 1.3mm.

[0045] According to one embodiment of the present invention, the diameter of the second segment 1202 is d1, and the diameter of the air intake 122 is d3, satisfying 0.45 ≤ d3 / d1 ≤ 0.55. Since the air intake 122 is located in the narrowed section, the dimensional relationship between the air intake 122 and the narrowed section affects foam generation. Specifically, if the diameter of the narrowed section is d1 and the diameter of the air intake 122 is d3, then 0.45 ≤ d3 / d1 ≤ 0.55 is satisfied. Specifically, when d3 / d1 < 0.45, the diameter of the air intake 122 is smaller than the diameter of the narrowing section. In this case, less air enters the foam generator 120 through the air intake 122, resulting in insufficient gas mixing with the liquid within the foam generator 120. This reduces the quality and quantity of foam produced, leading to a decrease in washing effect. When d3 / d1 > 0.55, the diameter of the air intake 122 is larger than the diameter of the narrowing section. In this case, an excessively large air intake 122 can easily cause leakage of the liquid mixture. Therefore, the diameter of the air intake 122 and the diameter of the narrowing section should be within a suitable range. For example, d3 / d1 is preferably 0.5. When d3 / d1 = 0.5, the foaming effect is better than other values ​​while ensuring sealing performance.

[0046] According to one embodiment of the present invention, 1.2mm ≤ d3 ≤ 2mm. Since the diameter of the air intake 122 affects the air entering the foam generating device 120, the diameter of the air intake 122 needs to be set within a suitable range. Specifically, when d3 < 1.2mm, the diameter of the air intake 122 is too small. In this case, the rate at which air enters the narrowed section is low, resulting in insufficient air intervention and less foam generated by the foam generating device 120, which leads to a reduction in the cleaning effect of the foam generating device 120. When d3 > 2mm, the diameter of the air intake 122 is too large, and in this case, detergent and water easily leak from the air intake 122. Therefore, 1.2mm ≤ d3 ≤ 2mm is a suitable range, and within this range, d3 can preferably be 1.3mm.

[0047] According to one embodiment of the present invention, the diameter of the second segment 1202 is d1, and the diameters of the first segment 1201 and the third segment 1203 are d4, satisfying 0.35≤d1 / d4≤0.45. Since the second segment 1202 is disposed between the first segment 1201 and the third segment 1203, and the second segment 1202 is constructed as a variable diameter segment, the relationship between the diameter of the second segment 1202 and the diameter of the third segment 1203 will affect the foaming effect of the mixture in the foam generating device 120. When d1 / d4 < 0.35, the second segment 1202 is too small compared to the third segment 1203. In this case, the flow velocity in the second segment 1202 is too high, and the detergent and water entering the second segment 1202 cannot mix completely in time, resulting in less foam. When d1 / d4 > 0.45, the second segment 1202 is too large compared to the third segment 1203. In this case, the flow velocity change between the second and third segments 1202 is very small, and the detergent and water mix thoroughly. Due to the small flow velocity change along the flow path, the mixture is relatively stable, resulting in less foam. Therefore, 0.35 ≤ d1 / d4 ≤ 0.45 is a suitable range, and within this range, d1 / d4 = 4 is preferred. It should be noted that the diameter of the first segment 1201 and the third segment 1203 can be the same.

[0048] The following is a brief description of the delivery component 1 according to the present invention.

[0049] The dispensing assembly 1 according to the present invention includes a foam generating device 120 and a foam dispensing device 16 as described in the above embodiments. The foam dispensing device 16 is connected to the foam generating device and is adapted to dispense foam generated by the foam generating device 120. The foam generating device 120 is mainly used to generate foam; while the foam dispensing device 16 is mainly used to dispense the foam mixture, but foam can also be generated in the foam dispensing device 16. Through the cooperation between the foam generating device 120 and the foam dispensing device 16, the foam dispensing assembly allows the detergent to be foamed multiple times before being used for washing. The foam-containing detergent mixture increases the contact area of ​​the items to be washed, resulting in better washing and improved cleaning performance of the dispensing assembly 1.

[0050] In some embodiments, such as Figure 3As shown, the foam dispensing device 16 is provided with a cylinder 164 and a spiral blade 165. The cylinder 164 has a cavity to accommodate the spiral blade 165. The spiral blade 165 is fixedly installed in the cavity of the cylinder 164 and can be used to cut the water flow. The foam dispensing device 16 can be connected to the outlet of the foam generating device 120 through the foam inlet 163 in the middle of the cylinder 164. The mixed liquid flowing out of the foam generating device 120 can enter the cylinder 164 through the foam inlet 163 and generate more foam under the action of the spiral blade 165. The mixed liquid with more foam can flow to the liquid outlet end from the first foam outlet 161 and the second foam outlet 162 at both ends of the cylinder 164.

[0051] In other embodiments, unlike the foam dispensing device 16 described above, the foam dispensing device 16 may also be equipped with a dispensing flow path and an impact flow path. The principles of the dispensing flow path and the impact flow path are similar to those of the foam generating device 120. The inlet of the dispensing flow path is connected to the outlet of the foam generating device 120, allowing the mixed liquid flowing out of the foam generating device 120 to enter the dispensing flow path. At this time, the impact flow path, connected to an external water source, can introduce water into the dispensing flow path, causing the mixed liquid in the dispensing flow path to mix with water again and foam. This can be simply understood as the mixed liquid undergoing the foaming process of the foam generating device 120 again in the dispensing flow path, further increasing the foam content. Similarly, an air inlet structure similar to the air intake 122 can also be provided on the dispensing flow path. The arrangement of the dispensing flow path and the impact flow path further increases the foam content in the mixed liquid finally flowing out from the outlet, improving the cleaning effect of the dispensing component 1.

[0052] The garment processing device according to the present invention is briefly described below.

[0053] The garment processing device according to the present invention includes the dispensing component 1 in the above embodiments. Since the garment processing device according to the present invention is provided with the dispensing component 1 in the above embodiments, the dispensing component 1 can be assembled into the workbench of the garment processing device. When the dispensing component 1 is assembled, the cleaning effect of the garment processing device can be improved, thereby improving the user experience.

[0054] In summary, the foam generating device 120 is provided with a first section 1201, a second section 1202, and a third section 1203 connected in sequence. The second section 1202 is provided with a liquid inlet 121 and an air intake 122. The size or size ratio of the first section 1201, the second section 1202, the third section 1203, the liquid inlet 121, and the air intake 122 is limited. Through reasonable planning and design, the efficiency of the liquid inlet 121 in receiving detergent, the efficiency of the air intake 122 in receiving air, and the combined flow rate of the mixed liquid in the second section 1202 and the third section 1203 are in a relatively balanced state. This can improve the foaming efficiency and foaming quality of the foam generating device 120, thereby improving the cleaning effect of the foam generating device 120.
