Abstract
Description
Technical Field
[0001] This utility model belongs to the field of washing equipment technology, and specifically relates to a detergent dispensing device and washing equipment with ozone function for use in merchandise display equipment. Background Technology
[0002] Currently, most washing equipment on the market (such as washing machines) uses ozone sterilization technology by directly adding an ozone generator module inside the washing equipment and using a Venturi tube structure to mix ozone with tap water. This either increases the size of the washing equipment or, if the size remains the same, increases the installation difficulty. Moreover, this method of using a Venturi tube structure results in low ozone mixing efficiency and unstable concentration control, which seriously reduces the sterilization and disinfection effect of the washing equipment. Furthermore, since ozone gas comes into direct contact with electronic components and plastic parts, it can easily cause oxidation and corrosion of these components, reducing the performance stability of the washing equipment (such as washing machines) and shortening its service life. Utility Model Content

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0027] like Figure 1-3 As shown in the figure, the detergent dispensing device with ozone function described in this embodiment of the present invention includes an automatic detergent dispensing module 100, an ozone generator module 200, and an ozone water mixing channel 300.
[0028] The automatic detergent dispensing module 100 includes a detergent dispensing box 101, a detergent dispensing pump 102, and a water inlet valve 103. The detergent dispensing pump 102 and the water inlet valve 103 are connected to the detergent dispensing box 101. Specifically... Figure 1 As shown, the automatic detergent dispensing module 100 is an automatic detergent dispensing system for washing machines, used for automatically dispensing detergent and fabric softener. It includes a detergent dispensing box 101 and a detergent dispensing pump 102. The detergent dispensing box 101 is equipped with a dual-chamber manual dispensing unit, which includes a detergent chamber and a fabric softener chamber, and is detachable for cleaning. The detergent dispensing pump 102 can be a peristaltic pump, and its pump pipe is connected to the dispensing pipe provided in the detergent chamber, the fabric softener chamber, and the detergent dispensing box 101. The water inlet valve 103 is connected to the dispensing pipe provided in the detergent dispensing box 101 through a first pipe 104 and a second pipe 105.
[0029] The ozone generator module 200 is integrated into the detergent automatic dispensing module 100 and is used to generate ozone gas. The ozone generator module 200 includes a pulse oscillation circuit and a high-voltage module group for generating ozone through corona discharge. Preferably, the ozone generator module 200 is an ozone generator module with adjustable ozone generation, and the adjustable ozone generation range is from 0.028 mg / s to 0.056 mg / s to suit different application scenarios.
[0030] The ozone water mixing channel 300 is installed on the detergent dispensing box 101. One end of the ozone water mixing channel 300 is connected to one outlet of the water inlet valve 103 and to the ozone gas output of the ozone generator module 200 (that is, one outlet of the water inlet valve 103 and the ozone gas output of the ozone generator module 200 are connected to the ozone water mixing channel 300 through the third pipe 106 and the fourth pipe 107, respectively). The other end is provided with an ozone water output. Thus, the detergent dispensing device of this invention can automatically dispense detergent while simultaneously delivering ozone water to the washing chamber of the washing equipment (e.g., the drum of a washing machine) to sterilize and disinfect the laundry, further improving the washing effect. Moreover, by using a separate ozone delivery pipeline to transport ozone gas from the ozone generator module to the ozone water mixing channel 300, the problem of ozone gas directly contacting electronic components and plastic parts and causing oxidation and corrosion of these components is avoided. This improves the performance of the detergent dispensing device, extends its service life, and reduces maintenance costs.
[0031] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the ozone-water mixing channel 300 of this invention is provided with a flow-limiting zone 301 and a vortex stirring zone 302 sequentially from one end connected to the ozone generator module 200 to the ozone-water output end. Wherein,
[0032] The flow-limiting zone 301 controls the water flow velocity and maintains the ozone concentration by reducing the cross-section of the flow channel; specifically, the flow-limiting zone 301 can be a flow channel with a flow-limiting structure. More specifically, the flow-limiting structure can be a raised curved surface 303 on the bottom surface of the ozone-water mixing flow channel 300 (see...). Figure 2 Alternatively, it could be a raised curved surface 303 provided on the side wall of the ozone water mixing channel 300 (see...). Figure 3 The raised curved surface 303 can be a protrusion formed in the ozone water mixing channel 300 by the inward deformation of the shell of the detergent dispensing box 101. Of course, the flow limiting structure can also be a raised curved surface 303 provided on the side wall and bottom surface of the ozone water mixing channel 300. The flow limiting area 301 is connected in sequence to one outlet end of the water inlet valve 103 and the ozone gas output end of the ozone generator module 200.
[0033] The vortex mixing zone 302 promotes the mixing of ozone gas and water by generating turbulence. Specifically, the structure can be as follows: the two side walls of the ozone-water mixing channel 300 are provided with protrusions 304. The protrusions 304 can be columnar bodies extending from the bottom surface to the top of the ozone-water mixing channel 300. The protrusions 304 on the two side walls are spaced apart and staggered to form the vortex mixing zone 302.
[0034] Furthermore, the ozone water mixing channel 300, the raised curved surface 303, the protrusion 304 and the detergent dispensing box 101 are integrated into one structure, specifically: the ozone water mixing channel 300, the raised curved surface 303, the protrusion 304 and the detergent dispensing box 101 are integrally injection molded.
[0035] This invention improves ozone mixing efficiency by setting up a flow restriction zone 301 and a vortex mixing zone 302, ensuring that the CT value of ozone water is ≤2, and has a significant disinfection effect on laundry.
[0036] Furthermore, the ozone-water mixing channel 300 of this invention is designed in an L-shape, with the flow-limiting zone 301 and the vortex stirring zone 302 respectively located on two mutually perpendicular sections of the L-shaped ozone-water mixing channel (300). This structure not only further improves the ozone mixing efficiency but also allows the ozone-water mixing channel 300 to be directly placed in the corner of the detergent dispensing box 101, reducing processing difficulty and cost.
[0037] The washing device described in this utility model includes the aforementioned detergent dispensing device with ozone function. This washing device can be a washing machine, dishwasher, etc.
[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
