The invention relates to a washing machine, in particular to the technical field of adding a clothes treating agent of the washing machine.
[ background of the invention ]
Washing machines are generally provided with a laundry treatment agent input device, in which a treatment agent is pre-added, which is input into the washing chamber during the running of the washing program. In the conventional liquid/gel type treating agent feeding device, the treating agent is usually in contact with the electric parts. These electrically powered parts include gear pumps, peristaltic pumps, valves, vacuum pumps, etc. for pumping fluids. The liquid will flow into the pump body and then flow out. It is very inconvenient to change the kind of the treating agent. Most gear pumps and peristaltic pumps are expensive in manufacturing cost, large in size, large in occupied space in batch production and high in cost.
In most of the existing treating agent input devices, the treating agent is in contact with air, and is difficult to ensure not to dry after being stored for a long time. Especially when used in higher temperature applications, such as near heating elements, high temperature elements, or in the vicinity of the drying tunnel of an integrated machine for washing and drying clothes. If the user does not use the water treatment agent for a long time, the water in the treatment agent evaporates and dries, so that the viscosity is increased, and the work of the pump body is even influenced.
The existing treatment agent input device generally adopts contact type induction, namely a probe or a sensor is contacted with liquid to induce whether the residual amount of the treatment agent is insufficient. Such sensing is subject to errors, such as variations in liquid level, tilt angle of the machine, and degree of liquid viscosity (which can be related to sensor sticking and surface tension). In addition, it is inconvenient to change the kind of liquid.
Some bottled treatment agent input devices have a valve at the outlet, which is opened to allow the liquid or gel treatment agent to flow out of the outlet under the influence of gravity. Due to the limitations of the internal space and structure of the washing machine, the outlet is often arranged on the side surface of the mounted treating agent bottle, but not on the bottom surface, so that residues are easy to exist, the treating agent is difficult to be thoroughly emptied, and waste is caused.

The suction device 10 comprises a reciprocally movable pressure head 12 and a feed channel 13 (shown in fig. 3) connected to the pressure head 12 and extending into the treatment agent container 5. Head 12 contains a discharge orifice 14. The outlet 14 is in spatial communication with the mixing chamber 8 such that the treating agent passes through the outlet 14 and enters the mixing chamber 8. In the embodiment shown in fig. 2, the head 12 is located above the mixing chamber 8 and the outlet 14 is located downwardly so that the treating agent flows out of the outlet 14 and enters the mixing chamber 8 under the influence of gravity. In other embodiments, the installation chamber 6 and the mixing chamber 8 can also be connected by a pipe, through which the treating agent enters the mixing chamber 8.
A pressure-exerting device 15 controlled by a control device 20 is arranged opposite the pressure head 12 and can push the pressure head 12 in the direction of approaching the treating agent container 5 so as to pump the treating agent out of the treating agent container 5.
In the embodiment shown in fig. 2, the pressing device 15 includes a driving part 151 and a moving part 152 driven by the driving part 151. The moving part 152 may include a reciprocating mechanism, a rotating mechanism, and the like, for example, a cam. The driving part 151 includes a motor. In one embodiment, the motor drives the cam to rotate, which in turn pushes the ram 12 to move. The moving part 152 in fig. 2 shows a side structure of the cam. The front view, i.e. in the direction of the axis of rotation, is a normal cam configuration. Fig. 2 in conjunction with the above text will understand the functional relationship of the cam structure to ram 12 to those skilled in the art.
In the embodiment shown in fig. 3, the pressure applying device 15 may further include a solenoid valve 153. Wherein the solenoid valve 153 includes a spool 154 that reciprocates to push the ram 12, a first spring 155 that acts axially on the spool 154, and a coil 156 that is disposed around the spool 154.

In the embodiment shown in fig. 2 and 3, the treatment agent container 5 is provided with a piston 51 which is in airtight contact with the wall 56 of the container, thereby dividing the treatment agent container 5 into a first chamber 501 on the side close to the ram 12 and a second chamber 502 remote from the ram 12. A treatment agent is contained in the first chamber 501. A vent 57 is provided in the bottom of the treating agent container 5 to vent the second chamber 502 to the atmosphere. As the amount of the treating agent decreases, the piston 51 moves closer to the ram 12 by the pressure difference, so that the treating agent is sufficiently used. Fig. 3 is a schematic diagram for explaining the functional features of the components simply, and in practical applications, it is possible to make the transport path 13 shorter, for example, so that the treating agent in the treating agent container 5 can be discharged sufficiently, and waste can be reduced.
The treating agent container 5 has a long structure, is disposed in the washing machine 1 in an axial direction horizontal or inclined with respect to the horizontal, and has a head 12 disposed at one axial end. This arrangement facilitates the treatment agent to fall under gravity directly into the mixing chamber 8 after being pressed out by the ram 12, thereby making construction and installation simple and easy to implement. Moreover, the piston 51 functions to sufficiently use the treating agent in the treating agent container 5 even when the treating agent container is not in an upright state.
As shown in fig. 1, 3 and 4, a detection device 18 is provided in the installation chamber 6 adjacent to the treatment agent container 5, by means of which detection device 18 a signal relating to the remaining amount of treatment agent can be obtained and transmitted to a control device 20. The control device 20 can then send the remaining amount indication information based on the remaining amount information of the treating agent. The washing machine generally comprises prompting means 40 arranged to send a prompt when the control means 20 receives an associated signal sent by the detection means 18 that there is a small residual amount of treating agent. The prompting message may be voice or visual. For example, the residual amount of the treating agent can be displayed on a display device, or a warning signal can be sent out when the residual grain is less than a set value, so that a user is reminded to replace the treating agent.
In various embodiments, the detection device 18 may be a load cell arranged below the treatment agent container 5; may be an optical sensor that detects a change in the liquid level in the treating agent container 5 or the position of the piston 51.
The detection means 18 may also be arranged to detect the position of the piston 51 and to send a corresponding signal to the control means 20. For example, the detection means 18 is disposed near the side of the first chamber 501 closer to the ram 12, so that when the remaining amount of the treating agent is small, the piston 51 moves to a position near the detection means 18, and the detection means 18 detects a change in the signal.
In some embodiments, the detection device 18 includes a color sensor. As the treating agent is consumed, the piston 51 moves. The color sensor initially detects the color of the treating agent and when the color changes to the color of the piston, indicating that the consumption of treating agent has reached a threshold, a signal may be sent.
In some embodiments, the detection device 18 includes a photosensor. The position of the piston can be determined by emitting and receiving light.
In some embodiments, the detection device 18 comprises a magnetic induction sensor and the piston 51 comprises a magnetic body 510. The signal of the proximity of the piston 51 to the position of the detection device 18 is obtained by the hall effect.
Since the pressing device 15 applies a pushing force to the ram 12, a stopper 30 for restricting the axial movement of the treating agent container 5 is provided in the installation chamber 6.
In the embodiment shown in fig. 2, the stopper portion 30 includes a stopper 31 provided near the bottom of the treating agent container 5. The bottom of the stop block 31 is provided with a second spring 32. Under the action of the second spring 32, the stopper 31 can extend into the space in the mounting cavity 6. And engages with the groove 50 on the treating agent container 5 to restrict the axial movement of the treating agent container 5 with the stopper 31 in the first position. Unlocking piece 33 is in sliding fit with the inclined surface of limiting block 31. The user presses the unlocking member 33 to force the stopper 31 out of engagement with the recess 50, thereby allowing the treating agent container 5 to move axially with the stopper 31 in the second position.
As shown in fig. 2, a third spring 63 is provided in the mounting chamber 6. The third spring 63 acts on the end face 55 of the treatment agent container 5 close to the ram 12 in the axial direction of the treatment agent container 5. Thus, when the movement restriction of the treating agent container 5 is released, that is, the stopper 31, 310 is moved from the first position to the second position, the treating agent container 5 is pushed to move in a direction to withdraw from the mounting chamber 6, and it is convenient for the user to take out the treating agent container 5 for replacement.
In addition to replacement of the treating agent container 5, it is also possible to make the treating agent container 5 openable so that the treating agent can be repeatedly added thereto.
The various embodiments described above and shown in the drawings are merely illustrative of the invention. Any modification of the present invention by a person of ordinary skill in the related art within the scope of the basic technical idea of the present invention is within the scope of the present invention.
