An embodiment of the utility model provides a metering device of detergent dispenser to reduce the occupation volume of detergent dispenser, and simplify the structure. This is explained below with reference to fig. 1 to 18.

The metering device is configured to provide a determined dose of the first fluid detergent into a washing chamber of the washing apparatus. For example, the first fluid detergent may be a brightener.

As shown in fig. 1, 4 to 10, the metering device includes: a housing 101, a valve body assembly VA, and a valve body driver 103.

As shown in fig. 1, 4 to 10, and 17 to 18, the housing 101 has a metering chamber C1, the metering chamber C1 is configured to store a determined dose of the first fluid detergent, and the metering chamber C1 has a liquid inlet K1, a liquid outlet K2, an air inlet K4, and an air outlet K3.

As shown in fig. 9 to 10 and 16 to 18, the valve body assembly VA is disposed in the metering chamber C1, and as shown in fig. 8, the valve body assembly VA includes a first valve body V1, a second valve body V2, and a first torsion spring S1, and the first torsion spring S1 is disposed between the first valve body V1 and the second valve body V2 and configured to apply force to the first valve body V1 and the second valve body V2 so that the first valve body V1 closes the liquid inlet K1 and the gas outlet K3, and so that the second valve body V2 closes the liquid outlet K2 and the gas inlet K4, respectively.

For example, the first torsion spring S1 is provided between the first valve body V1 and the second valve body V2 and configured to urge the first valve body V1 and the second valve body V2, respectively, such that the first valve body V1 closes the liquid inlet K1 and the gas outlet K3 when the second valve body V2 is opened, and such that the second valve body V2 closes the liquid outlet K2 and the gas inlet K4 when the first valve body V1 is opened.

A first torsion spring S1 is arranged between the first valve body V1 and the second valve body V2, so that the first valve body V1 and the second valve body V2 can be interlocked, when one of the first valve body V1 and the second valve body V2 is opened, the other one of the first valve body V1 and the second valve body V2 is pressed to block a corresponding opening under the action of the first torsion spring S1, and the phenomenon that four openings are opened simultaneously is avoided.

For example, the first torsion spring S1 is disposed between the first valve body V1 and the second valve body V2 and configured to urge the first valve body V1 and the second valve body V2, respectively, such that the first valve body V1 closes the liquid inlet port K1 and the gas outlet port K3 in a natural state (neither the first valve body V1 nor the second valve body V2 is operated), and such that the second valve body V2 closes the liquid outlet port K2 and the gas inlet port K4 in the natural state, but is not limited thereto.

As shown in fig. 10 to 15, the metering device includes: a valve body driver 103, the valve body driver 103 being configured to drive the first valve body V1 and configured to drive the second valve body V2. Referring to fig. 10 to 13, and 16 to 18, the valve body driver 103 is configured to drive the first valve body V1 to rotate to open the liquid inlet port K1 and the gas outlet port K3 to feed liquid and/or to drive the second valve body V2 to rotate to open the liquid outlet port K2 and the gas inlet port K4 to discharge liquid. The valve body driving member 103 is configured to drive the first valve body V1 to rotate at a first timing to open the liquid inlet K1 and the gas outlet K3 to feed liquid and to drive the second valve body V2 to rotate at a second timing to open the liquid outlet K2 and the gas inlet K4 to discharge liquid. The first time and the second time are different times.

As shown in fig. 1, 4 to 5, 9 to 10, and 16 to 18, the casing 101 further includes a diversion cavity C3, and the diversion cavity C3 is respectively communicated with the liquid inlet K1 and the gas outlet K3, so that when the first valve body V1 in the metering cavity C1 is opened, the fluid can enter the metering cavity C1 through the diversion cavity C3, and the gas in the metering cavity C1 can be discharged into the diversion cavity C3. For example, the fluid is a brightener.

As shown in fig. 1, 2 and 3, the chamber cover 201 may be welded to the housing 101, so that the metering chamber C1 becomes a sealed chamber and the diversion chamber C3 becomes a sealed chamber. Fig. 2 is a schematic diagram of a side of the chamber cover 201 away from the housing, and fig. 3 is a schematic diagram of a side of the chamber cover 201 close to the housing 201. Fig. 2 and 3 show the front and back of the chamber cover 201, respectively. The front surface of the chamber cover 201 shown in fig. 2 is the side away from the metering chamber C1, and the back surface of the chamber cover 201 shown in fig. 3 is the side close to the metering chamber C1.

As shown in fig. 2 and 3, the chamber cover 201 has a shaft hole 202, an exhaust hole 203, and an inlet hole 204. The exhaust hole 203 and the liquid inlet hole 204 are respectively communicated with the diversion cavity C3. Fig. 3 shows a weld bead 205 on the back of the cavity cover 201.

As shown in fig. 1, the metering chamber C1 and the diversion chamber C3 form a chamber C0, and referring to fig. 1 to 3, the chamber cover 201 is a structure for sealing the chamber C0, and the shape of the chamber cover 201 conforms to the chamber C0. The front face of the chamber cover 201 may be provided with a raised gland and gland seal.

The metering chamber C1 and the diversion chamber C3 are integrally connected to the dispenser, and are chambers surrounded by the housing 101 and the chamber cover 201. For example, plastic is used for both the housing 101 and the chamber cover 201.

For example, as shown in fig. 10 to 15, the valve body driving member 103 includes a first lever L1, the valve body assembly VA is disposed on the first lever L1, and the first valve body V1 and the second valve body V2 are sequentially disposed on the first lever L1 in an extending direction of the first lever L1. For example, the first valve body V1, the first torsion spring S1, and the second valve body V2 are sequentially provided on the first lever L1 in the extending direction of the first lever L1. For example, the first torsion spring S1 may be sleeved on the first lever L1.

As shown in fig. 10 to 15, the first lever L1 has a catch 104, the first valve body V1 has a first spindle catch 111, the second valve body V2 has a second spindle catch 112, and the first spindle catch 111 and the second spindle catch 112 are disposed in the catch 104.

The chamber cover 201 is omitted from FIG. 10 for clarity in viewing the valve body assembly VA in the metering chamber C1. The first shift lever L1 passes through the shaft hole 202 in the chamber cover 201. The gear G1 and the locking groove 104 on the first shift lever L1 are respectively arranged on two sides of the cavity cover 201.

For example, as shown in fig. 8 and 11, the first valve body V1 has a first shaft hole 131, the second valve body V2 has a second shaft hole 132, and the first lever L1 passes through the first shaft hole 131 and the second shaft hole 132.

For example, as shown in fig. 8, the first shaft stopper 111 protrudes from the first body B1 of the first valve body V1 toward the center of the first shaft hole 131 so that the first lever L1 drives the first valve body V1 to rotate through the first shaft stopper 111, and the second shaft stopper 112 protrudes from the second body B2 of the second valve body V2 toward the center of the second shaft hole 132 so that the first lever L1 drives the second valve body V2 to rotate through the second shaft stopper 112.

For example, as shown in fig. 12, a central angle A0 of the card slot 104 is twice a central angle A1 of the first shaft stopper 111, and a central angle A0 of the card slot 104 is twice a central angle A2 of the second shaft stopper 112. For example, as shown in fig. 12, the central angle A1 is equal to the central angle A2.

For example, as shown in fig. 8 to 13 and 16, the first valve body V1 and the second valve body V2 are provided in an X shape. For example, in some embodiments, when one of the first valve body V1 and the second valve body V2 is opened to the maximum angle and abuts against the other of the first valve body V1 and the second valve body V2, the arrangement may prevent the simultaneous opening of the liquid inlet K1, the liquid outlet K2, the air inlet K4, and the air outlet K3 after the failure of the first torsion spring S1.

For example, as shown in fig. 6 and 8, both ends of the first torsion spring S1 abut against the first valve body V1 and the second valve body V2, respectively, so that the liquid inlet port K1 and the liquid outlet port K2 are alternatively closed.

For example, as shown in fig. 4 and 5, the metering chamber C1 has a top wall W1 and a bottom wall W2, the liquid inlet K1 and the liquid outlet K2 are located in the bottom wall W2, and the air inlet K4 and the air outlet K3 are located in the top wall W1, so as to ensure that liquid inlet is not insufficient due to gas in the metering chamber during liquid inlet, and facilitate discharge of fluid in the metering chamber. The liquid inlet K1 is located in the bottom wall W2, the air exhaust port K3 is located in the top wall W1, so that the vertical distance between the liquid inlet K1 and the air exhaust port K3 is enlarged, the pressure difference between the liquid inlet K1 and the air exhaust port K3 is increased, and the reliability of liquid inlet is improved. A drain K2 is located in the bottom wall W2 to drain the fluid in the metering chamber clean. Meanwhile, the air inlet K4 is positioned in the top wall W1 to enlarge the vertical distance between the liquid outlet K2 and the air inlet K4, increase the pressure difference between the two and improve the liquid discharging reliability. Air inlet K4 and gas vent K3 are arranged in roof W1, do benefit to the increase pressure differential, increase the reliability of feed liquor and flowing back.

As shown in fig. 4 and 5, the side surface of the metering chamber C1 has four holes, which are a liquid inlet K1, a liquid outlet K2, an air inlet K4 and an air outlet K3. For example, one of the two air ports (the air outlet K3) in the top wall W1 leads to the diversion cavity C3, and the other of the two air ports (the air inlet K4) in the top wall W1 leads to the back side and is connected with the outside (for visual reasons, the position of the air inlet K may be right above the liquid inlet K1, such as the air inlet 122 shown in fig. 20); the diversion cavity C3 is connected with the metering cavity C1 through the liquid inlet K1, and the air outlet K3 is also communicated with the metering cavity C1 and the diversion cavity C3, so that a cavity C0 is formed.

For example, as shown in fig. 6, the first valve body V1 has a liquid inlet end E1 and a gas outlet end E3 spaced from each other, the liquid inlet end E1 and the gas outlet end E3 of the first valve body V1 are respectively provided with a sealing cap, the second valve body V2 has a liquid outlet end E2 and a gas inlet end E4 spaced from each other, and the liquid outlet end E2 and the gas inlet end E4 of the second valve body V2 are respectively provided with a sealing cap, so as to facilitate the improvement of sealing performance and the liquid inlet and discharge of the metering chamber C1. Fig. 6 shows a sealing cap 141, a sealing cap 142, a sealing cap 143, and a sealing cap 144. As shown in fig. 6, the sealing cap 141, the sealing cap 142, the sealing cap 143, and the sealing cap 144 are disposed at the inlet end E1, the drain end E2, the exhaust end E3, and the inlet end E4, respectively.

For example, as shown in fig. 6 and 7, both ends (torsion arms) of the first torsion spring S1 may be disposed at the exhaust end E3 of the first valve body V1 and the intake end E4 of the second valve body V2, respectively, but are not limited thereto. The first valve body V1 and the second valve body V2 may be provided with a groove to set the torsion arm of the first torsion spring S1. Fig. 6 shows a groove GR1 in the first valve body V1. A similar groove is also provided in the second valve body V2. For example, as shown in fig. 6, the valve body assembly VA includes a first valve body V1, a second valve body V2, a first torsion spring S1, and four sealing caps.

For example, as shown in fig. 10 to 15, a gear G1 is provided on the first shift lever L1 to form a gear shift lever 105, and the gear shift lever 105 and the valve body assembly VA are coaxially coupled.

The utility model provides a metering device needs to carry out external drive, consequently, controls valve body subassembly VA through gear driving lever 105 and accomplishes corresponding mechanical action, accomplishes the realization to the measurement of first fluid detergent.

For example, as shown in fig. 10, the metering device further includes a gear driving member 106, and the gear driving member 106 is configured to drive a gear G1 on the first shift lever L1 to drive the first shift lever L1, and further drive the first valve body V1 or the second valve body V2.

For example, as shown in fig. 10, the gear drive 106 includes a motor 161, a worm 162 connected to the motor 161, a helical gear 163 connected to the worm 162, and a drive gear 164 engaged with the helical gear 163, the drive gear 164 being engaged with the gear G1 (the gear on the gear shifter lever 105) on the first shifter lever L1. The motor 161 is, for example, a dc motor. The motor 161, the worm 162, the helical gear 163, the driving gear 164, the gear shift lever 105 (the first shift lever L1), and the valve body assembly VA form a continuous transmission system.

For example, as shown in fig. 1, 4, 5, 16-18, the housing 101 has a limit stop 107 within the metering chamber C1, the limit stop 107 being configured to limit the valve body assembly VA. For example, as shown in fig. 1, 4, 5, and 16 to 18, one limit stop 107 is provided at each of two opposite positions of the valve body assembly VA. For example, the limit stop 107 is tile-shaped.

For example, as shown in fig. 1, 4, 5, 16 to 18, the limit stop 107 is located at the center of the metering chamber C1, and is two tile-like structures, which are formed to surround, so as to mount and fix the valve body assembly.

For example, as shown in fig. 2, 3 and 5, shaft hole 202 is used to mount gear shifter lever 105. The liquid inlet hole 204 is used to take fluid (e.g., brightener) from within a fluid storage chamber (e.g., brightener storage chamber), for example. The exhaust hole 203 is used to exhaust the gas in the metering chamber C1 to a fluid storage chamber (brightener storage chamber). The gas in the metering cavity C1 can be discharged into the diversion cavity C3 through the gas outlet K3, enter the gas outlet 203 through the diversion cavity C3, and can be discharged to the fluid storage cavity through the gas outlet 203.

The manner in which the metering device is mounted is described below. As shown in fig. 8, the metering device is mainly mounted by mounting the valve body assembly VA and the metering chamber C1.

First, the valve body assembly VA is assembled, as shown in fig. 8, four sealing caps are mounted at the corresponding ends to constitute the first valve body V1 and the second valve body V2, and then the first valve body V1 and the second valve body V2 are assembled, and the first valve body V1 and the second valve body V2 are connected by the first torsion spring S1.

Then, the valve body assembly VA is installed in the metering chamber C1, that is, the entire valve body assembly VA is installed between the two limit baffles 107 of the metering chamber C1, and the valve body assembly VA is installed in the metering chamber C1, as shown in fig. 9, the valve body assembly VA and the metering chamber C1 are combined into a final metering device, and after all the steps are completed, the chamber cover 201 is welded. The chamber cover 201 is welded to the housing 101.

Finally, the valve body assembly VA is connected to the gear shift lever 105. As shown in fig. 15, the card slot 104 located at the upper side has two opposite side walls 104a and 104b, and referring to fig. 13 and 15, the side wall 104a contacts with the side wall 104b, the side wall 104a contacts with the first rotation axis stopper 111, and correspondingly, the side wall 104b contacts with the second rotation axis stopper 112. That is, for the upper card slot 104, the first shaft gear 111 is located at the right side and the rear end, and the second shaft gear 112 is located at the left side and the front end, which is closer to the gear G1 than the rear end.

As shown in fig. 11 to 13, the diagonal section line in fig. 12 is a first shaft stopper 111 of the first valve body V1, which contacts the right side (side wall 104 a) of the upper side of the slot 104 on the shaft (first lever L1) of the gear lever 105 during assembly, and leaves a space for shaft stopper on the left side of the slot 104, which just satisfies that when the gear lever 105 rotates in the arrow direction (counterclockwise) shown in fig. 12, the first valve body V1 is driven to rotate in the arrow direction shown in fig. 12 by a shaft stopper angle, at this time, the first valve body V1 rotates to the maximum angle, and at this time, the first valve body V1 can abut against the second valve body V2 to realize interlocking. Similarly, as shown in fig. 11 to fig. 13, the cross section line in fig. 12 is a second shaft stopper 112 of the second valve body V2, and contacts with the left side (side wall 104 b) of the upper side notch 104 on the gear stopper 105, when the gear stopper 105 rotates, the second valve body V2 is driven to rotate in the direction (clockwise) opposite to the arrow shown in fig. 12, and the spatial range of the rotation is also an angle of the shaft stopper; because the section angle (central angle) of the clamping groove 104 is 2 times of the central angle of the rotating shaft block, when one of the first valve body V1 and the second valve body V2 rotates, the space of the rotating shaft block is still rotated, and the other valve body cannot be driven, so that only one of the first valve body V1 and the second valve body V2 can be driven to rotate during unidirectional rotation. The above description is made with the direction of the arrow in fig. 12 being counterclockwise, the direction of the arrow in fig. 12 corresponds to the direction of the arrow in fig. 11, and the direction of the arrow in fig. 11 is clockwise if viewed from the gear side of the gear shift lever 105 in fig. 11. Fig. 15 does not show the catch groove of the first lever L1 on its lower side.

For example, in the process of completing the driving of the first valve body V1 and returning the gear shift lever 105, the first valve body V1 can follow the return under the action of the first torsion spring S1 to wait for the next action of the first valve body V1. Accordingly, in the process of completing the driving of the second valve body V2 and returning the gear shift lever 105, the second valve body V2 can follow the return under the action of the first torsion spring S1 to wait for the next action of the second valve body V2.

As shown in fig. 11, the first valve V1 has a first abutting portion Vc, so that when the first valve V1 acts and rotates to a maximum angle, the first valve V1 abuts against the second valve V2, so as to avoid the second valve V2 acting at the moment, and prevent the four openings from being opened simultaneously after the first torsion spring S1 fails. As shown in fig. 11, the second valve body V2 has a second abutting portion Vd, so that when the second valve body V2 acts and rotates to a maximum angle, the second valve body V2 abuts against the first valve body V1, so as to avoid the action of the first valve body V1, and prevent the four openings from being opened simultaneously after the first torsion spring S1 fails.

The metering device mainly adopts the working principle that the fluid is controlled by the alternating opening and closing of a first valve body V1 and a second valve body V2 in a valve body assembly VA, and the valve body assembly VA mainly has three states, namely a natural state (shown in figure 16), a liquid inlet state (shown in figure 17) and a liquid discharge state (shown in figure 18).

As shown in fig. 16, in the natural state, the first valve body V1 and the second valve body V2 are not actuated, that is, both the first valve body V1 and the second valve body V2 are in the closed state. As shown in fig. 16, in a natural state, the first valve body V1 closes the liquid inlet K1 and the gas outlet K3, and the second valve body V2 closes the liquid outlet K2 and the gas inlet K4.

As shown in fig. 17, in the intake state, the first valve V1 is actuated, and the second valve V2 is not actuated, that is, the first valve V1 is opened and the second valve V2 is closed. During the feed liquor state, inlet K1 opens, and gas vent K3 opens, as shown in fig. 17, and the inlet K1 of left downside opens, and the gas vent K3 of upper right side opens to can not make and remain the air in the measurement chamber C1, avoid causing the condition of measurement chamber C1 feed liquor and not flowing back.

As shown in fig. 18, in the liquid discharge state, the first valve V1 is not actuated, and the second valve V2 is actuated, that is, the first valve V1 is in the closed state, and the second valve V2 is open. The leakage fluid port K2 is opened, the air inlet K4 is opened, as shown in fig. 18, the leakage fluid port K2 on the lower right side is opened, the air inlet K4 on the upper left side is opened, the leakage fluid port K2 discharges fluid, and the air inlet K4 admits air, so that the air pressure in the metering cavity C1 is balanced, and the incomplete drainage condition is avoided.

For the first valve body V1 and the second valve body V2, the liquid discharging state and the liquid inlet state are just opposite to each other.

The operation of the valve body assembly will be explained below.

As shown in fig. 11 to 15, the valve body assembly operates on the principle that the valve body assembly VA is controlled by a gear shift lever 105 of the driving system.

The central shaft (first shift lever L1) of the gear shift lever 105 drives the first valve body V1 or the second valve body V2 in the valve body assembly VA to rotate by driving the rotating shaft block (first rotating shaft block 111 or second rotating shaft block 112) to rotate, because the rotating angle of the first rotating shaft block 111 or the second rotating shaft block 112 is half of the central angle of the slot 104, and the two opposite side walls of the clamping groove are respectively contacted, so that only one of the first valve body V1 and the second valve body V2 can be driven during rotation, and under the action of the first torsion spring S1, the other one of the first valve body V1 and the second valve body V2 can be forced by the first torsion spring S1 to press the corresponding opening to generate interlocking.

The gear shift lever 105 is driven by the motor to rotate forward or backward to control the orderly rotation of the valve body assembly VA so as to timely open or close the related opening of the metering cavity, thereby realizing the quantitative feeding of the brightener.

For example, when the gear shift lever 105 rotates one of the two valve bodies via the shaft shift, the torsion force (elastic restoring force) of the first spring S1 needs to be overcome.

Drive valve body assembly VA through gear driving lever 105, valve body assembly VA accomplishes corresponding action, specifically is: first valve body V1 moves, and inlet K1 and gas vent K3 open, then leakage fluid dram K2 and air inlet K4 are then died and are closed, and is corresponding, second valve body V2 moves, and leakage fluid dram K2 and air inlet K4 open, then inlet K1 and gas vent K3 died and close. This action is performed once for each dosing of fluid (e.g., brightener).

Although the above description has been made by taking the example of the measurement chamber C1 for feeding the brightener, the measurement chamber C1 may be used for feeding the dishwashing liquid as long as the dishwashing liquid is fed in a predetermined amount.

The embodiment of the utility model also provides a detergent dispenser for washing equipment, including any above-mentioned metering device.

As shown in fig. 1 and 10, the housing 101 has a wall C20 for forming a housing chamber C2, and the housing chamber C2 and the chamber body C0 are divided at opposite sides of the housing 101. For example, the housing chamber C2 is located at the back side of the housing 101, and the chamber body C0 is located at the front side of the housing 101.

An embodiment of the utility model provides a detergent dispenser for washing equipment, except containing the above-mentioned metering device who puts in the first fluid detergent of confirming the dosage, can also contain the device that is used for putting in the solid detergent.

The third shift lever L3 drives the second shift lever L2 by abutting against the second shift lever L2, and further drives the main body MP. The third lever L3 may also be referred to as a plunger. The driving gear 164 is driven by the third lever L3 (pressing lever) to transmit to the slide cover driving member 301.

For example, as shown in fig. 21, the detergent dispenser further includes a second torsion spring S2, and the second torsion spring S2 is disposed on the main body portion MP and configured to return the lever portion 302 (the second lever L2 and the main body portion MP). The second torsion spring S2 can function to reset the slide cover driver 301 (the lever portion 302). For example, the body portion MP may drive the catch 191 to reciprocate between the first position and the second position. One of the first position and the second position is a position where the catch 191 catches the button 109, and the other of the first position and the second position is a position where the catch 191 releases the button 109.
