Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A dispensing assembly for dispensing a lotion according to an embodiment of the present invention, which can be used in a dispensing device of a washing appliance such as a washing machine for dispensing a lotion into a washing space, is described below with reference to fig. 1.
As shown in fig. 1, a dispensing assembly for dispensing a lotion according to an embodiment of the first aspect of the present invention comprises: a main vessel shell 1 and a connecting pipe 2.
The main pipe shell 1 is provided with a liquid inlet end and a liquid outlet end, water is suitable for flowing into the main pipe shell 1 through the liquid inlet end and flowing out of the liquid outlet end, a suction inlet 10 is formed in the side wall of the main pipe shell 1, the suction inlet 10 is located between the liquid inlet end and the liquid outlet end, lotion can flow into the main pipe shell 1 through the suction inlet 10, the connecting pipe 2 is arranged at the suction inlet 10, and the connecting pipe 2 is communicated with the suction inlet 10.
The negative pressure generated by the flow of water in the main pipe shell 1 can be used as a driving force to suck the lotion into the main pipe shell 1 through the connecting pipe 2 and the suction inlet 10, for example, the main pipe shell 1 can be a venturi tube. The lotion may be sucked into the main pipe casing 1 through the connection pipe 2 and the suction port 10 by a pumping action of a pump or the like as power. Alternatively, when the main tube housing 1 is a venturi tube, the lotion is sucked into the main tube housing 1 through the connection tube 2 and the suction port 10 by the negative pressure generated by the flow of the water flow in the main tube housing 1 and the suction action of the pump.
The connection pipe 2 is formed with an air inlet 20, the air introduced from the air inlet 20 is suitable for flowing into the main pipe case 1 through the suction port 10, the air introduced from the air inlet 20 may be air, and the air enters the connection pipe 2 from the air inlet 20 and is sucked into the main pipe case 1 through the suction port 10. The negative pressure generated by the flow of water in the main pipe housing 1 can be used as a driving force to suck gas into the main pipe housing 1 through the connecting pipe 2 and the suction port 10, for example, the main pipe housing 1 can be a venturi tube. The gas may be sucked into the main tubular housing 1 through the connection pipe 2 and the suction port 10 by a suction action of a pump or a fan using the pump, the fan, or the like as power. Alternatively, when the main tube housing 1 is a venturi tube, the gas is sucked into the main tube housing 1 through the connection tube 2 and the suction port 10 by the negative pressure generated by the flow of the water flow in the main tube housing 1 and the suction action of the pump or the blower.
Therefore, when the putting assembly is used for the putting device of the washing machine, the putting device can put the washing agent into the washing barrel of the washing machine. In the process of putting the lotion by using the putting component, water enters the main pipe shell 1 through the liquid inlet end of the main pipe shell 1, the lotion and gas entering from the gas inlet 20 enter the main pipe shell 1 through the suction inlet 10, and the gas, the water and the lotion are mixed in the main pipe shell 1, so that the lotion is fully dissolved, and the lotion flows into a washing barrel of the washing machine through the liquid outlet end after being fully dissolved. Therefore, after the lotion enters the main pipe shell 1, the lotion is dissolved in the water flow in the main pipe shell 1, and at the same time, because the air enters the main pipe shell 1, the dissolution of the lotion can be promoted through the sufficient mixing of the air, the water and the lotion, for example, when the lotion is a detergent, the foaming effect of the lotion can be improved, the foam after foaming is more fine, and the cleaning effect is improved.
In the process of using the above-mentioned dosing assembly to dose the lotion, the lotion can be supplied first and then the gas can be supplied through the suction port 10, the gas can be supplied first and then the lotion can be supplied through the suction port 10, or the lotion and the gas can be alternately supplied. The water flow in the main pipe casing 1 may be opened before, after, or during the administration of the gas and the detergent, or the water flow in the main pipe casing 1 may be alternated with the administration of the gas and the detergent. Wherein, the rivers in being responsible for shell 1 are opened before the input of gas and lotion, and lotion and gas can just contact rivers from the beginning like this, and make lotion not too much accumulation in the pipeline for lotion dissolves abundant, even, reduces and remains the caking risk, thereby reduces the pipeline and blocks up the risk.
The lotion comprises detergent, softener, disinfectant and the like, namely the lotion generally refers to additives for putting in a laundry process. When the washing machine is in a washing stage, detergent can enter the main pipe shell 1 through the suction port 10; when the washing machine is in the rinsing stage, softener and disinfectant can enter the main casing 1 through the suction opening 10. After the corresponding detergent is put in the washing stage and the rinsing stage of the washing machine, a water flow may be sucked through the suction port 10 to wash the suction port 10. In both the washing stage and the rinsing stage, the air inlet 20 is ventilated and the air introduced from the air inlet 20 is adapted to flow into the main casing 1 through the air inlet 10, thereby promoting the thorough mixing and dissolution of the detergent, softener and disinfectant.
Because the dispensing assembly can fully dissolve the lotion in water, the lotion can play a more sufficient role in the washing process, for example, the cleaning effect can be improved, the hand feeling can be improved, and the disinfection rate can be improved. In addition, the supply of the lotion and the supply of the gas share one suction port 10, so that the structure of the dispensing assembly is compact, and the occupied space is saved.
According to the dispensing assembly for dispensing the lotion, the air inlet 20 is arranged, so that the air is introduced into the main pipe shell 1 through the air inlet 20 in the process that the lotion flows into the main pipe shell 1 through the suction inlet 10, the lotion can be fully dissolved in water flow through the disturbance effect of the air, the foaming effect of the lotion can be improved, the cleaning effect can be improved, the caking risk of the residual lotion can be reduced, and the blocking risk of a pipeline can be reduced. In addition, the supply of the lotion and the supply of the gas share one suction port 10, so that the structure of the dispensing assembly is compact, and the occupied space is saved.
According to some embodiments of the present invention, referring to fig. 1, the main tube housing 1 is a venturi tube, the main tube housing 1 includes a first tube segment 11, a second tube segment 12 and a third tube segment 13 connected in sequence, the flow area of the second tube segment 12 is smaller than the flow area of the first tube segment 11 and smaller than the flow area of the third tube segment 13, the liquid inlet end is located in the first tube segment 11, the liquid outlet end is located in the third tube segment 13, and the suction inlet 10 is formed in the first tube segment 11 or the second tube segment 12. By setting the main pipe housing 1 as a venturi tube, water flows into the first pipe section 11 through the liquid inlet end and then flows through the second pipe section 12 and the third pipe section 13 in sequence, and because the flow area of the second pipe section 12 is the smallest, a large negative pressure can be generated in the process that water flows through the second pipe section 12. When the suction opening 10 is formed in the first pipe section 11 or the second pipe section 12, the above-mentioned negative pressure effect can be utilized so that the lotion and the gas are sucked into the main housing 1 through the suction opening 10. Wherein, the lotion and the gas can enter the main shell 1 through the suction inlet 10 only by the negative pressure; alternatively, the gas enters the main casing 1 through the suction port 10 by the above-mentioned negative pressure action, and the lotion enters the main casing 1 through the suction port 10 mainly by the pumping action of the pump.
In addition, in the process of mixing the detergent, the gas and the water flow in the second pipe section 12, since the flow area of the second pipe section 12 is small, the water flow speed is increased, and the turbulent motion effect is good, the mixing effect is good, the dissolving effect and the foaming effect of the detergent can be further improved, and the cleaning effect can be improved.
According to some embodiments of the invention, referring to fig. 1, an inner tube 3 is provided within the main vessel shell 1, the inner tube 3 having an inlet adjacent the inlet end and an outlet 30, water being adapted to flow into the inner tube 3 through the inlet and out of the outlet 30 into the main vessel shell 1. Wherein, water can directly flow into the inner tube 3 through the inlet, and water also can flow into the liquid inlet end firstly and then flows into the inner tube 3 through the inlet of the inner tube 3. From this, through being equipped with inner tube 3 in being responsible for shell 1, and make rivers flow in inner tube 3, because the cross-sectional area of inner tube 3 can be less than main tube shell 1's cross-sectional area, thereby can increase the velocity of flow of rivers, the velocity of flow can increase after the inner tube 3 is flowed through to the rivers, rivers can be with higher velocity of flow blowout from the export 30 of inner tube 3, reinforcing rivers are to the impact effect of lotion, make water, lotion and gas three intensive mixing, the foaming, and then can further improve the dissolution effect and the foaming effect of lotion, improve the washing effect.
According to some alternative embodiments of the present invention, referring to fig. 1, a flow space 301 is defined between an outer sidewall of an inner pipe 3 and an inner sidewall of a main pipe case 1, and a suction port 10 is formed on the outer sidewall of the flow space 301. Therefore, in the process that the lotion and the gas enter the main pipe shell 1 through the suction port 10, the lotion and the gas can enter the flowing space 301 through the suction port 10, so that the lotion and the gas are fully mixed before contacting with the water flow, and the lotion and the gas are fully mixed in the flowing space 301 and then contact with the water flow, thereby further improving the dissolving effect and the foaming efficiency of the lotion and further improving the cleaning effect.
In some alternative embodiments of the invention, referring to fig. 1, the cross-section of the flow space 301 is annular extending around the inner tube 3. Thereby, the flow space 301 is made large, so that the lotion and the gas can be sufficiently mixed in the flow space 301.
In some alternative embodiments of the present invention, referring to fig. 1, the inner tube 3 includes a main body section 31 and a compression section 32 connected to each other, the compression section 32 may be a tube section having a uniform inner diameter, an inlet is formed in the main body section 31, an outlet 30 is formed in the compression section 32, and a flow area of the compression section 32 is smaller than that of the main body section 31. From this, at the in-process of rivers flow through inner tube 3, rivers pass through the in-process of compression section 32, and rivers can further be accelerated to make rivers can be from export 30 blowout with higher speed, further increase the impact force of rivers, further make water, lotion and gas intensive mixing, foaming, and then can further improve the dissolving effect and the foaming effect of lotion, improve the washing effect.
Alternatively, referring to fig. 1, the suction port 10 is located upstream of the compression section 32 (the expression "the suction port 10 is located upstream of the compression section 32" means that the suction port 10 is located upstream of the entire compression section 32, with respect to the flow direction of the water flow). Thereby, a certain distance is provided between the suction inlet 10 and the outlet 30 of the inner tube 3, so that the wash solution and the gas can be mixed with sufficient space and time before the wash solution and the gas contact the water flow after the wash solution and the gas enter the flow space 301 through the suction inlet 10.
Alternatively, referring to fig. 1, the inner tube 3 includes a connecting section 33, the connecting section 33 connects the main body section 31 and the compression section 32, an outer side wall of the connecting section 33 extends obliquely toward a direction adjacent to the central axis of the main tube shell 1 in a direction from the main body section 31 to the compression section 32, a minimum flow area of the connecting section 33 is not smaller than a flow area of the compression section 32, and the suction port 10 is located upstream of the connecting section 33 (the "suction port 10 is located upstream of the connecting section 33" means that the suction port 10 is located upstream outside the entire connecting section 33, with respect to a flow direction of the water flow). Thus, the change in the flow area between the main body segment 31 and the compression segment 32 is alleviated by the provided connection segment 33, and the flow loss can be reduced. Also, since the suction inlet 10 is located upstream of the connection section 33, the distance between the suction inlet 10 and the outlet 30 of the inner tube 3 can be further increased, so that the wash and gas can be more sufficiently mixed in space and time before the wash and gas contact the water flow. In addition, after the lotion and the gas sucked from the suction port 10 enter the flow space 301, the lotion and the gas can more smoothly flow forward to contact with the water flow by the guide action of the outer side wall of the connection section 33.
In some alternative embodiments of the present invention, referring to fig. 1, the main pipe shell 1 is a venturi tube, the main pipe shell 1 includes a first pipe segment 11, a second pipe segment 12 and a third pipe segment 13 connected in sequence, the flow area of the second pipe segment 12 is smaller than that of the first pipe segment 11 and smaller than that of the third pipe segment 13, the liquid inlet end is located in the first pipe segment 11, the liquid outlet end is located in the third pipe segment 13, the inner pipe 3 is arranged in the first pipe segment 11, a flow space 301 is defined between the outer side wall of the inner pipe 3 and the inner side wall of the first pipe segment 11, and the outlet 30 is adjacent to the second pipe segment 12. By setting the main pipe shell 1 as a venturi tube, water flow enters the first pipe section 11 through the liquid inlet end and then flows through the second pipe section 12 and the third pipe section 13 in sequence, and because the flow area of the second pipe section 12 is the smallest, large negative pressure can be generated in the process that water flow passes through the second pipe section 12, and lotion and gas can be sucked into the main pipe shell 1 through the suction inlet 10 by utilizing the negative pressure effect. Wherein, the lotion and the gas can enter the main shell 1 through the suction inlet 10 only by the negative pressure; alternatively, the gas enters the main casing 1 through the suction port 10 by the above-mentioned negative pressure action, and the lotion enters the main casing 1 through the suction port 10 mainly by the pumping action of the pump.
In addition, in the process of mixing the detergent, the gas and the water flow in the second pipe section 12, since the flow area of the second pipe section 12 is small, the water flow speed is increased, and the turbulent motion effect is good, the mixing effect is good, the dissolving effect and the foaming effect of the detergent can be further improved, and the cleaning effect can be improved.
Further, through setting up inner tube 3 in first pipeline section 11, because the cross-sectional area of inner tube 3 can be less than the cross-sectional area of main tube shell 1, thereby can increase the velocity of flow of rivers, the velocity of flow can increase after the rivers flow through inner tube 3, rivers can be in higher velocity of flow blowout to second pipeline section 12 from the export 30 of inner tube 3, strengthen the impact effect of rivers, and combine lotion and gas to inhale flow space 301 through sunction inlet 10 and fully mix after flowing into second pipeline section 12 and contact rivers, make water, lotion and gas fully mix, the foaming in main tube shell 1, and then can further improve the dissolving effect and the foaming effect of lotion, improve the washing effect.
According to some embodiments of the present invention, a control valve for opening and closing the intake port 20 is provided at the intake port 20. Thereby, the control of the gas into the main vessel shell 1 is facilitated. For example, when the control valve is open, gas may enter from the gas inlet 20 and flow into the main housing 1 from the suction inlet 10; when the control valve is closed, the supply of gas into the main pipe casing 1 is stopped.
In some optional embodiments of the present invention, the main pipe shell 1 is the main pipe shell 1, the main pipe shell 1 includes a first pipe segment 11, a second pipe segment 12 and a third pipe segment 13, which are connected in sequence, a flow area of the second pipe segment 12 is smaller than a flow area of the first pipe segment 11 and smaller than a flow area of the third pipe segment 13, a liquid inlet end is located in the first pipe segment 11, a liquid outlet end is located in the third pipe segment 13, a suction port 10 is formed in the first pipe segment 11 or the second pipe segment 12, the control valve is a one-way valve, and the one-way valve is in one-way communication in a direction from the air inlet 20 to the suction port 10. Thus, by providing the main housing 1 as a venturi and forming the suction inlet 10 in the first or second pipe section 11, 12, the negative pressure effect generated by the water flow can be utilized during the water flow through the main housing 1, at which time the check valve opens under the effect of the pressure difference, thereby allowing gas, such as air, to enter from the inlet port 20; when the water supply flow in the main pipe case 1 is stopped, the check valve is closed. Therefore, the control of the control valve is convenient and reliable.
