[0034] like Figure 1-Figure 9 As shown, the utility model provides a dispensing device, which includes a detergent box 100 and a foam generating box 200. The detergent box 100 is used to store detergent. The foam generating box 200 is provided with a slow flow structure 201, which is used to slow down the flow rate of the detergent flowing through the foam generating box 200. The outlet of the detergent box 100 is connected to the inlet of the foam generating box 200, and the outlet of the foam generating box 200 is connected to the detergent dispensing port of the washing drum 300.
[0035] It should be noted that the detergent box 100 can be connected to an external water supply pipe, so that the detergent in the detergent box 100 flows to the foam generating box 200 under the action of the water flow, and is dissolved and mixed in the foam generating box 200. The detergent box 100 can also not be connected to an external water pipe, but only rely on the gravity of the detergent to make the detergent flow into the foam generating box 200 through the pipeline, and mix with the water flow provided by the external water supply pipe of the foam generating box 200 and dissolve therein.
[0036] It is understandable that the foam generating box 200 is provided with a slow flow structure 201, which is used to slow down the flow rate of the detergent flowing through the foam generating box 200, so that the detergent can slow down the flow rate in the foam generating box 200, so that it has enough time to dissolve. That is, the utility model increases the dissolution time of the detergent in the foam generating box 200 by adding the foam generating box 200 between the detergent box 100 and the washing drum 300, thereby improving the dissolution effect of the detergent.
[0037] In some embodiments, the foam generating box 200 is a hollow structure, and has at least one slow flow structure 201 therein, and the at least one slow flow structure 201 is disposed near the inlet of the foam generating box 200 .
[0038] It can be understood that the slow flow structure 201 is arranged near the inlet of the foam generating box 200, which can slow down the detergent or the mixed solution of detergent at the first time, so that the detergent can flow in the foam generating box 200 for a longer time, so that it can be fully dissolved and mixed, thereby improving the washing effect.
[0039] In some embodiments, the flow-slowing structure 201 includes a plurality of flow-blocking columns spaced apart along the width direction of the foam generating box 200 .
[0040] It can be understood that the baffle column can collide with the detergent or the detergent solution when the detergent or the detergent mixed solution enters the foam generating box 200, thereby reducing its flow rate.
[0041] In some embodiments, each flow-delaying structure 201 includes three flow-blocking columns, and the three flow-blocking columns are arranged at intervals along the width direction of the foam generating box 200 .
[0042] In some embodiments, the slow-flow structure 201 is a baffle disposed along the width direction of the foam generating box 200 , and the height of the baffle is 0.4-0.6 times the height of the foam generating box 200 .
[0043] It is understandable that the baffle is arranged along the width direction of the foam generating box 200, and the height is about half of the foam generating box 200, so as to better slow down the detergent or detergent solution. At the same time, the height of the baffle is maintained at about half of the height of the foam generating box 200, which can ensure that the detergent has a better slowing effect and can smoothly flow out of the foam generating box 200.
[0044] In some embodiments, the top of the baffle is flush with the center of the inlet of the foam generating box 200 .
[0045] In some embodiments, the top of the baffle is lower than the center of the inlet of the foam generating box 200 .
[0046] In some embodiments, the foam generating box 200 has a plurality of slow flow structures 201 , and the plurality of slow flow structures 201 are arranged at intervals along a direction from an inlet of the foam generating box 200 toward an outlet of the foam generating box 200 .
[0047] That is, a plurality of blocking pieces are arranged at intervals along the inlet of the foam generating box 200 toward the outlet of the foam generating box 200 .
[0048] Alternatively, a plurality of slow flow structures 201 are arranged at intervals along the inlet of the foam generating box 200 toward the outlet of the foam generating box 200 , and each slow flow structure 201 includes three flow blocking columns arranged at intervals along the width direction of the foam generating box 200 .
[0049] In some embodiments, the detergent box 100 includes an upper cover 101, a drawer portion 102 and a lower box body 103. The upper cover 101 and the lower box body 103 are covered together to form a box cavity. The drawer portion 102 is pluggable in the box cavity. When the drawer portion 102 is inserted into the box cavity, the box cavity is divided into an upper box cavity and a lower box cavity that are interconnected. The drawer portion 102 is used to store detergent. The upper cover 101 has a water inlet, and the lower box body 103 has a liquid outlet. The liquid outlet is connected to the inlet of the foam generating box 200.
[0050] It is understandable that the water inlet is connected to a water supply pipe, and after the water flows into the drawer portion 102 , it takes away the detergent in the drawer portion 102 and flows into the foam generating box 200 through the liquid outlet of the lower box body 103 .
[0051] In some embodiments, the drawer portion 102 includes two storage cavities, and holes are provided at the bottom of the storage cavity so that the detergent flows into the lower box body 103 through the holes. The two storage cavities can store different detergents respectively, or the same detergent.
[0052] In some embodiments, a plurality of guide plates 1011 are disposed on the inner surface of the upper cover 101 , so that water flows into the detergent box 100 from the water inlet and falls evenly into various positions of the drawer portion 102 under the guiding effect of the guide plates 1011 .
[0053] In some embodiments, the delivery device further includes a water inlet module 500 , and the water inlet module 500 has a water supply port, which is connected to the water inlet of the upper cover 101 .
[0054] It should be noted that the water inlet module 500 is connected to a water supply device, which may be a water storage tank or an external faucet, etc. The water inlet module 500 is used to control the flow rate and flow rate of water supplied to the upper cover 101 .
[0055] In some embodiments, the delivery device also includes a venturi tube 400, the inlet end of the venturi tube 400 is connected to the water supply port of the water inlet module 500, the diffusion end of the venturi tube 400 is connected to the inlet of the foam generating box 200, and a liquid supply pipe is connected between the throat of the venturi tube 400 and the liquid outlet of the lower box body 103.
[0056] It should be noted that, in some embodiments, the water inlet module 500 has at least two water supply ports, one for supplying water to the upper cover 101 , and one for supplying water to the venturi tube 400 .
[0057] In other embodiments, the water inlet module 500 may also have only one water supply port, which is connected to the water inlet of the upper cover 101 and the inlet end of the venturi tube 400 at the same time, that is, it supplies water to both of them at the same time.
[0058] The water inlet module 500 may be an electrically controlled valve or a water pump.
[0059] Since the throat of the venturi tube 400 is connected to the liquid outlet of the lower box body 103 through the liquid delivery pipe, when the water inlet module 500 supplies water to the venturi tube 400, a negative pressure is formed at the liquid delivery pipe, thereby sucking the detergent solution in the lower box body 103 into the venturi tube 400, and flowing into the foam generating box 200 along with the water flow in the venturi tube 400, and then fully dissolved in the foam generating box 200.
[0060] In some embodiments, the diameter of the liquid delivery tube gradually decreases from the lower box body 103 toward the venturi tube 400 .
[0061] That is, the liquid delivery pipe has an inverted cone structure, and the end with a smaller radius is connected to the throat of the venturi tube 400, so that the detergent solution entering the liquid delivery pipe can quickly enter the venturi tube 400.
[0062] In some embodiments, the inner tube of the liquid delivery tube is cylindrical.
[0063] In some embodiments, the dispensing device further includes a spray head 600 , which is embedded in the inner wall of the washing tub 300 , and the outlet of the foam generating box 200 is connected to the inlet of the spray head 600 .
[0064] In some embodiments, the utility model further provides a washing machine, including the above-mentioned delivery device. Since the washing machine has the delivery device of any one of the above-mentioned embodiments or a combination of multiple embodiments, the washing machine at least has some or all of the beneficial effects of the above-mentioned delivery device, which will not be described one by one here.
[0065] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the application concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
