[0001] The present invention relates to the technical field of clothing processing equipment, and specifically provides a clothing dispensing device, a washing device and a control method for the washing device. Background Art

[0002] During the use of the delivery device, a reminder to add more will usually be given after it is used up, but it is difficult for users to know the remaining amount of the delivery device. Therefore, when the remaining amount of the delivery device is low, the last delivery amount is difficult to meet the usage needs.

[0003] In the prior art, in order to prevent the last dosage of the delivery device from failing to meet the usage demand, a real-time flow meter is usually provided for the delivery device so that the user can know the real-time flow of the delivery agent. However, the cost of the real-time flow meter is relatively high and it is difficult to meet the purchasing requirements of users.

[0004] Accordingly, the art requires a dispensing device, a washing device and a control method for the washing device to solve the above technical problems. Summary of the invention

[0005] The present invention aims to solve the above technical problem, that is, in the prior art, the cost of real-time flow meters is relatively high and it is difficult to meet the purchasing requirements of users.

[0008] A liquid level detection device is provided in the temporary storage box.

[0009] The first delivery pump is provided with a first liquid inlet, and the first liquid inlet is connected to the upper part of the temporary storage box.

[0010] The second delivery pump is provided with a second liquid inlet, and the second liquid inlet is connected to the lower part of the temporary storage box.

[0011] In a specific embodiment of the above delivery device, the delivery device further includes a flow channel,

[0012] The first delivery pump is provided with a first liquid outlet.

[0013] The second delivery pump is provided with a second liquid outlet.

[0014] The first liquid outlet and the second liquid outlet are both communicated with the flow channel.

[0015] In a specific embodiment of the above-mentioned delivery device, a first valve body and a second valve body are arranged in the flow channel.

[0016] The first valve body is disposed at the connection between the first liquid outlet and the flow channel.

[0017] The second valve body is arranged at the connection between the second liquid outlet and the flow channel.

[0018] In a specific embodiment of the above-mentioned delivery device, the liquid level detection device includes a magnetic induction element and a reed switch.

[0019] The magnetic induction element floats in the temporary storage box.

[0020] The reed switch is arranged on the upper side of the temporary storage box.

[0021] When the liquid in the temporary storage box is full, the distance between the magnetic induction component and the reed switch is less than or equal to a threshold value, and the reed switch reaches a passage state.

[0022] In the case of adopting the above technical solution, the delivery equipment provided by the present invention includes a storage box, a temporary storage box, a first delivery pump and a second delivery pump. The storage box is connected to the temporary storage box, and a liquid level detection device is provided in the temporary storage box. The liquid inlet of the first delivery pump is connected to the upper part of the temporary storage box, and the liquid inlet of the second delivery pump is connected to the lower part of the temporary storage box. Based on the above structural setting, the liquid level detection device can detect the liquid level height of the temporary storage box. When the liquid level detection device detects that the liquid in the temporary storage box is full, delivery is performed through the first delivery pump; when the liquid level detection device detects that the liquid in the temporary storage box cannot be full, the second delivery pump is used for the last delivery. Therefore, when the second delivery pump is activated, the delivery equipment is the last delivery, and there is no need to set a real-time flow meter, which can solve the problem that the last delivery amount of the delivery equipment cannot meet the use demand.

[0023] Furthermore, the washing equipment provided by the present invention is provided with a flow channel, so that the first delivery pump and the second delivery pump extract liquid from the temporary storage box and then deliver it out through the flow channel.

[0024] Furthermore, the washing equipment provided by the present invention is provided with a first valve body and a second valve body, wherein, when the first delivery pump is started, the first valve body opens, allowing the liquid to flow from the temporary storage tank into the flow channel. Similarly, when the second delivery pump is started, the second valve body opens, allowing the liquid to flow from the temporary storage tank into the flow channel.

[0025] Furthermore, the washing equipment provided by the present invention defines that the liquid level detection device includes a magnetic sensing component and a reed switch. When the liquid in the temporary storage box is full, the distance between the magnetic sensing component and the reed switch is less than or equal to the threshold value, and the reed switch reaches a passage state. Therefore, it is possible to determine whether the temporary storage box is in a full liquid state by the on and off state of the reed switch.

[0027] The dispensing device is connected to the washing tub, wherein the capacity of the temporary storage box is greater than or equal to the amount of detergent dispensed required for one washing procedure.

[0028] The first delivery pump and the second delivery pump are both used to deliver the detergent in the temporary storage box into the washing tub.

[0029] Based on the above structural setting, the liquid level detection device can detect the liquid level height of the temporary storage box. When the liquid level detection device detects that the liquid in the temporary storage box is full, the liquid is dispensed through the first delivery pump; when the liquid level detection device detects that the liquid in the temporary storage box cannot be full, the second delivery pump is used to perform the final delivery. Therefore, the washing equipment can solve the problem that the final delivery amount of detergent is difficult to meet the usage needs without setting a real-time flow meter.

[0030] In a third aspect, the present invention further provides a control method for a washing device, wherein the washing device comprises a delivery device and a washing drum, the delivery device is connected to the washing drum, the delivery device comprises a storage box, a temporary storage box, a first delivery pump and a second delivery pump, the storage box is connected to the temporary storage box, a liquid level detection device is arranged in the temporary storage box, the first delivery pump is provided with a first liquid inlet, the first liquid inlet is connected to the upper part of the temporary storage box, the second delivery pump is provided with a second liquid inlet, the second liquid inlet is connected to the lower part of the temporary storage box, the first delivery pump and the second delivery pump are both used to deliver the detergent in the temporary storage box into the washing drum, the control method comprises:

[0034] According to the liquid level information of the liquid level detection device detected in real time, when the liquid level information of the liquid level detection device is lower than a preset height, the first delivery pump is controlled to be closed, and the second delivery pump is controlled to be opened.

[0035] When adopting the above technical solution, the present invention preliminarily obtains the liquid level information of the liquid level detection device to determine whether the washing liquid in the temporary storage box is full. When the liquid level detection device detects that the washing liquid in the temporary storage box is full, the washing program is started, and the liquid level information of the liquid level detection device continues to be obtained in real time to detect the liquid height in the temporary storage box in real time. When the liquid level detection device detects that the washing liquid in the temporary storage box cannot be full, it means that the washing liquid can only meet the last delivery demand at this time, so the first delivery pump is controlled to be closed, and the second delivery pump is controlled to be turned on to complete the last washing.

[0036] In a specific implementation of the control method of the washing equipment, the liquid level detection device includes a magnetic induction element and a reed switch, wherein the magnetic induction element floats in the temporary storage box, and the reed switch is arranged on the upper side of the temporary storage box.

[0055] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios. For example, although this specific embodiment is described in conjunction with the control method of a washing device applied to a washing device, the control method of a washing device of the present invention can obviously also be used in other devices. Such changes in the relevant application scenarios do not deviate from the basic principles of the present invention and belong to the scope of protection of the present invention.

[0056] During use, the delivery device usually gives a reminder to add more after it is used up, but it is difficult for the user to know the remaining amount of the delivery device. Therefore, when the remaining amount of the delivery device is small, its last delivery amount cannot meet the use demand. In the prior art, in order to avoid the last delivery amount of the delivery device being unable to meet the use demand, the delivery device is usually provided with a real-time flow meter so that the user can know the real-time flow rate of the delivery agent. However, the cost of the real-time flow meter is high and it is difficult to meet the purchase requirements of users.

[0057] First, see Figure 1 , Figure 1 Schematic diagram of the cross section of the delivery device provided by the present invention. Figure 1 As shown, the present invention provides a delivery device, which includes a storage box 1, a temporary storage box 2, a first delivery pump 3 and a second delivery pump 4, wherein the storage box 1 is connected to the temporary storage box 2, a liquid level detection device 5 is provided in the temporary storage box 2, the first delivery pump 3 is provided with a first liquid inlet 31, the first liquid inlet 31 is connected to the upper part of the temporary storage box 2, and the second delivery pump 4 is provided with a second liquid inlet 41, the second liquid inlet 41 is connected to the lower part of the temporary storage box 2. Based on the above structural setting, the liquid level detection device 5 can detect the liquid level height of the temporary storage box 2. When the liquid level detection device 5 detects that the liquid in the temporary storage box 2 is full, delivery is performed through the first delivery pump 3; when the liquid level detection device 5 detects that the liquid in the temporary storage box 2 is not full, the second delivery pump 4 is used to perform the last delivery. Therefore, when the second delivery pump 4 is enabled, the delivery device is the last delivery, and there is no need to set a real-time flow meter, which can solve the problem that the last delivery amount of the delivery device is difficult to meet the use demand.

The first valve body 61 is provided at the connection between the first liquid outlet 32 ​​and the flow channel 6, and the second valve body 62 is provided at the connection between the second liquid outlet 42 and the flow channel 6. When the first delivery pump 3 is started, the first valve body 61 is opened, so that the liquid flows from the temporary storage tank 2 into the flow channel through the first valve body 61; similarly, when the second delivery pump 4 is started, the second valve body 62 is opened, so that the liquid flows from the temporary storage tank into the flow channel through the second valve body 62, and then flows out through the flow channel 6.

[0060] In this preferred embodiment, the liquid level detection device 5 includes a magnetic sensing element 51 and a reed switch 52, wherein the magnetic sensing element 51 floats in the temporary storage box 2, and the reed switch 52 is arranged on the upper side of the temporary storage box 2. When the liquid in the temporary storage box 2 is full, the distance between the magnetic sensing element 51 and the reed switch 52 is less than or equal to the threshold value, and the reed switch 52 reaches a passage state. Therefore, it is possible to judge whether the temporary storage box 2 is in a full liquid state by the on-off state of the reed switch 52.

[0061] In addition, the present invention also provides a washing device, which includes the dispensing device and a washing drum (not shown in the figure) described in the above embodiment, wherein the dispensing device is connected to the washing drum, wherein the capacity of the temporary storage box 2 is greater than or equal to the amount of detergent dispensed required for a washing procedure, and the first dispensing pump 3 and the second dispensing pump 4 are both used to dispense the detergent in the temporary storage box 2 into the washing drum. Based on the above structural setting, the liquid level detection device 5 can detect the liquid level height of the temporary storage box 2. When the liquid level detection device 5 detects that the liquid in the temporary storage box 2 is full, the first dispensing pump 3 is used to dispense; when the liquid level detection device 5 detects that the liquid in the temporary storage box 2 is not full, the second dispensing pump 4 is used to perform the last dispensing. Therefore, the washing device can solve the problem that the last dispensing amount of detergent is difficult to meet the use demand without setting a real-time flow meter.

[0062] On the other hand, the present invention also provides a control method for a washing device, the washing device comprises a dispensing device and a washing drum, the dispensing device is connected to the washing drum, the dispensing device comprises a storage box, a temporary storage box, a first dispensing pump and a second dispensing pump, the storage box is connected to the temporary storage box, a liquid level detection device is arranged in the temporary storage box, the first dispensing pump is provided with a first liquid inlet, the first liquid inlet is connected to the upper part of the temporary storage box, the second dispensing pump is provided with a second liquid inlet, the second liquid inlet is connected to the lower part of the temporary storage box, and the first dispensing pump and the second dispensing pump are both used to dispense the detergent in the temporary storage box into the washing drum. Figure 2 , Figure 2 A flow chart of a control method for a washing device provided by the present invention, such as Figure 2 As shown, the control method of the washing device provided by the present invention includes:

[0063] S1: Preliminarily obtain the liquid level information of the liquid level detection device,

[0064] S2: according to the liquid level information of the liquid level detection device detected initially, when the liquid level information of the liquid level detection device reaches a preset height, starting the washing program;

[0065] S3: controlling the first delivery pump to start, so as to deliver detergent into the washing tub, and continuing to obtain the liquid level information of the liquid level detection device in real time;

[0066] S4: According to the liquid level information of the liquid level detection device detected in real time, when the liquid level information of the liquid level detection device is lower than a preset height, the first delivery pump is controlled to be closed, and the second delivery pump is controlled to be opened.

[0067] When adopting the above technical solution, the present invention preliminarily obtains the liquid level information of the liquid level detection device to determine whether the washing liquid in the temporary storage box is full. When the liquid level detection device detects that the washing liquid in the temporary storage box is full, the washing program is started, and the liquid level information of the liquid level detection device continues to be obtained in real time to detect the liquid height in the temporary storage box in real time. When the liquid level detection device detects that the washing liquid in the temporary storage box cannot be full, it means that the washing liquid can only meet the last delivery demand at this time, so the first delivery pump is controlled to be closed, and the second delivery pump is controlled to be turned on to complete the last washing.

[0068] Refer to the following Figure 3 ,in, Figure 3 This is a flow chart of the second embodiment of the control method of the washing equipment of the present invention, and introduces the second embodiment of the control method of the washing equipment of the present invention. Among them, the liquid level detection device in the washing equipment includes a magnetic induction component and a reed switch, wherein the magnetic induction component floats in the temporary storage box, and the reed switch is arranged on the upper side of the temporary storage box. When the liquid in the temporary storage box is full, the distance between the magnetic induction component and the reed switch is less than or equal to the threshold value, and the reed switch reaches a passage state. In the second embodiment of the present invention, the control method of the washing equipment includes:

[0069] S201: Preliminary detection of the on / off status of the reed switch.

[0070] S202: According to the on / off state of the reed switch detected initially, when the reed switch is in the on state, the washing program is started;

[0071] S203: Controlling the first dispensing pump to start, so as to dispense detergent into the washing tub, and continuing to detect the on / off state of the reed switch in real time;

[0072] S204: According to the on-off state of the reed switch detected in real time, when the reed switch is in an open circuit state, the first delivery pump is controlled to be turned off, and the second delivery pump is controlled to be turned on.

[0073] In the case of adopting the above technical scheme, the present invention preliminarily judges the on-off state of the reed switch to determine whether the washing liquid in the temporary storage box is full. When the reed switch is in the on state, that is, the washing liquid in the temporary storage box is full, the washing program is started, and the on-off state of the reed switch is continued to be judged in real time to detect the liquid height in the temporary storage box in real time. When the reed switch is in the off state, that is, the washing liquid in the temporary storage box cannot be filled, it means that the washing liquid can only meet the last delivery demand at this time, so the first delivery pump is controlled to be closed, and the second delivery pump is controlled to be turned on to complete the last washing.

[0074] Refer to the following Figure 4 ,in, Figure 4 The flowchart of the third embodiment of the control method of the washing machine of the present invention is introduced. In the third embodiment of the present invention, the control method of the washing machine includes:

[0075] S301: Preliminary detection of the on / off status of the reed switch.

[0076] S302: According to the on / off state of the reed switch detected initially, when the reed switch is in the on state, the washing program is started;

[0077] S303: Controlling the first dispensing pump to start, so as to dispense detergent into the washing tub, and continuing to detect the on / off state of the reed switch in real time;

[0078] S304: According to the on-off state of the reed switch detected in real time, when the reed switch is in an open circuit state, the first delivery pump is controlled to be turned off, and the second delivery pump is controlled to be turned on;

[0079] S305: After the washing program is finished, the alarm device is controlled to turn on the alarm to prompt the user to add detergent or replace the storage box.

[0080] In another possible implementation, the above step S301 further includes:

[0081] S3011: According to the on-off state of the reed switch detected initially, when the reed switch is in an off state, the first dispensing pump is controlled to start so as to replenish detergent into the temporary storage box;

[0082] S3012: Real-time detection of the on / off status of the reed switch within the preset time.

[0083] S3013: according to the on / off state of the reed switch detected in real time within a preset time, when the reed switch is in a conductive state, the washing program is started;

[0084] S3014: Based on the on / off state of the reed switch detected in real time within a preset time, when the reed switch is not in a conductive state, the alarm device is controlled to turn on the alarm to prompt the user to add detergent or replace the storage box.

[0085] When the above technical solution is adopted, when it is initially detected that the reed switch is in an open circuit state, it means that the temporary storage box is not full at this time. In this state, the first delivery pump is controlled to start so that the detergent is added to the temporary storage box. During the adding process, the on and off state of the reed switch is detected in real time. When the reed switch appears in a through state, it means that the temporary storage box has been filled with detergent, and the user can start the washing program. When the reed switch does not appear in a through state, it means that the temporary storage box cannot be filled with detergent, that is, the existing detergent cannot be used for the last washing program, that is, the washing program cannot be started, and it is necessary to turn on an alarm to prompt the user to add detergent or replace the storage box.

[0086] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.

[0087] Those skilled in the art can understand that the above-mentioned washing device and control method thereof also include some other well-known structures, such as processors, controllers, memories, etc., wherein the memories include but are not limited to random access memory, flash memory, read-only memory, programmable read-only memory, volatile memory, non-volatile memory, serial memory, parallel memory or registers, etc., and the processors include but are not limited to CPLD / FPGA, DSP, ARM processor, MIPS processor, etc. In order to unnecessarily obscure the embodiments of the present disclosure, these well-known structures are not shown in the drawings.
