Description

Technical Field

[0001] This utility model relates to the field of recreational vehicle technology, and in particular to a water pump control system. Background Technology

[0002] Motorhomes are typically equipped with two water pumps: a domestic water pump and an electric water filling pump. The domestic water pump draws water from the fresh water tank to supply water-using equipment; the electric water filling pump pumps water into the fresh water tank through an electric water inlet to quickly replenish the tank.

[0003] Current recreational vehicle designs feature separate water pumps for domestic use and electric water filling, controlled independently with no complementary functions. Due to differences in usage frequency and scenarios, the failure rate of domestic water pumps is significantly higher than that of electric water filling pumps. When the domestic water pump malfunctions, the water system becomes unusable, rendering water-using equipment unusable and requiring repair. Utility Model Content

[0004] This utility model provides a water pump control system to achieve linkage control of domestic water pump and electric water pump, and solve the water supply problem of the motorhome when the domestic water pump fails.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0022] It should be noted that current domestic water pumps and electric water pumps are two independent pumping units, controlled separately, with no complementary functions. Due to differences in usage frequency and scenarios, the failure rate of domestic water pumps is much higher than that of electric water pumps. When a domestic water pump fails, the water system becomes unusable, and water-using equipment cannot function properly, requiring repair.

[0023] Based on this, the present invention provides a water pump control system. Figure 1 This is a structural schematic diagram of a water pump control system provided by this utility model. This embodiment is applicable to the control of domestic water pumps and electric water pumps. Figure 1As shown, the water pump control system includes: a domestic water pump 1, an electric water filling pump 2, a first electric three-way ball valve 3, a second electric three-way ball valve 4, a clean water tank 5, a water-using device 6, an electric water inlet 7, and a flow control module 8. The first electric three-way ball valve 3 is connected to the domestic water pump 1, the clean water tank 5, and the electric water filling pump 2. The second electric three-way ball valve 4 is connected to the electric water filling pump 2, the clean water tank 5, and the water-using device 6. The domestic water pump 1 is connected to the water-using device 6 and is used to supply water to the water-using device 6. The electric water filling pump 2 is connected to the electric water inlet 7 and is used to supply water to the electric water filling pump 2. The flow control module 8 is connected to the domestic water pump 1, the electric water filling pump 2, the first electric three-way ball valve 3, and the second electric three-way ball valve 4. The first electric three-way ball valve 3 and the second electric three-way ball valve 4 switch flow paths under the control of the flow control module 8.

[0024] In this context, a water pump can be understood as a device used to transport water. Domestic water pump 1 can be understood as a device used to transport water from the clean water tank 5 to the water-using equipment 6. Domestic water pump 1 can be a device that uses electrical energy to transport water. Electric water pump 2 can be understood as a device used to transport water flowing from the electric water inlet 7 to the clean water tank 5. Electric water pump 2 can also be a device used to transport water from the clean water tank 5 to the water-using equipment 6. The purpose of electric water pump 2 is related to the state of the water pump control system. Electric water pump 2 can also be a device that uses electrical energy to transport water.

[0025] A three-way ball valve can be understood as a valve device used to control the flow of water. A three-way ball valve can include three pipe interfaces for connecting to different pipes, allowing water to switch in three directions. An electric three-way ball valve is a type of three-way ball valve driven by electrical energy. The first electric three-way ball valve 3 can be understood as an electric three-way ball valve connected to the domestic water pump 1, the clean water tank 5, and the electric water filling pump 2. Through the first electric three-way ball valve 3, water can flow from the clean water tank 5 to either the domestic water pump 1 or the electric water filling pump 2. The second electric three-way ball valve 4 can be understood as an electric three-way ball valve connected to the electric water filling pump 2, the water-using equipment 6, and the clean water tank 5. Through the second electric three-way ball valve 4, water can flow from the electric water filling pump 2 to either the clean water tank 5 or the water-using equipment 6.

[0026] The fresh water tank 5 can be understood as a container used for storing and supplying water on the motorhome. During the motorhome's operation, the water in the fresh water tank 5 can be supplied to the water-using equipment 6. When the electric water inlet 7 is connected to an external water supply device, the water supplied by the water supply device can be stored in the fresh water tank 5.

[0027] Water-using equipment 6 refers to all water-using devices inside the RV's passenger compartment, such as sink faucets and bathroom showerheads. Both domestic water pump 1 and electric water pump 2 can supply water to water-using equipment 6.

[0028] The electric water inlet 7 can be understood as a device used to supply water from an external water supply device to the recreational vehicle. Through the electric water inlet 7, external water can be supplied to the electric water pump 2 and stored in the clean water tank 5.

[0029] The access control module 8 can be understood as a module used to control the domestic water pump 1, the electric water filling pump 2, the first electric three-way ball valve 3, and the second electric three-way ball valve 4 in the water pump control system. The access control module 8 may include devices in the water pump control system that can be controlled by electrical energy.

[0030] In this embodiment, since the first electric three-way ball valve 3 and the second electric three-way ball valve 4 can change the water flow direction, the water pump control system can provide two water supply schemes for the water-using equipment 6. One scheme, when the domestic water pump is working normally, allows water from the clean water tank 5 to be supplied to the domestic water pump 1 via the first electric three-way ball valve 3, and then the domestic water pump 1 supplies water to the water-using equipment 6. The other scheme, when the domestic water pump 1 malfunctions, allows water from the clean water tank 5 to be supplied to the electric water pump 2 via the first electric three-way ball valve 3, and then the electric water pump 2 supplies water to the water-using equipment 6 via the second electric three-way ball valve 4.

[0031] For example, Figure 2 This is a structural schematic diagram of a pipeline connection method provided by this utility model. For example... Figure 2 As shown, three-way ball valve 1 is the first electric three-way ball valve 3, and three-way ball valve 2 is the second electric three-way ball valve 4. Three-way ball valve 1 includes three pipe interfaces: A, B, and C. A is connected to the clean water tank, B is connected to the electric water pump M2, and C is connected to the domestic water pump M1. Therefore, three-way ball valve 1 allows water to flow between the clean water tank, the electric water pump M2, and the domestic water pump M1. Similarly, three-way ball valve 2 also includes three pipe interfaces: A, B, and C. A is connected to the electric water pump M2, B is connected to the water-using equipment, and C is connected to the clean water tank. Therefore, three-way ball valve 2 allows water to flow between the clean water tank, the electric water pump M2, and the water-using equipment.

[0032] The technical solution of this utility model embodiment provides a water pump control system, including: a domestic water pump, an electric water filling pump, a first electric three-way ball valve, a second electric three-way ball valve, a clean water tank, water-using equipment, an electric water inlet, and a flow control module. The first electric three-way ball valve is connected to the domestic water pump, the clean water tank, and the electric water filling pump. The second electric three-way ball valve is connected to the electric water filling pump, the clean water tank, and the water-using equipment. By adding the first and second electric three-way ball valves, the water flow direction of the water pump control system can be changed, realizing the linkage control of the domestic water pump and the electric water filling pump. The domestic water pump is connected to the water-using equipment and is used to supply water to the equipment. The electric water filling pump is connected to the electric water inlet, and the electric water inlet is used to supply water to the electric water filling pump. In the event of a malfunction of the domestic water pump, the flow direction can be changed by altering the first electric three-way ball valve. The passage of the ball valve and the second electric three-way ball valve allows the electric water pump to continue supplying water to the water-using equipment, ensuring the normal operation of the equipment. The passage control module is connected to the domestic water pump, the electric water pump, the first electric three-way ball valve, and the second electric three-way ball valve. The first electric three-way ball valve and the second electric three-way ball valve switch passages under the control of the passage control module. Through the passage control module, in the event of a failure of the domestic water pump, the working state of the water pump control system can be switched with one button, solving the water supply problem of the RV when the domestic water pump fails, improving the convenience of operation, and enhancing the user experience.

[0033] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0034] In one embodiment, the first electric three-way ball valve 3 includes a first passage 31 and a second passage 32. The first passage 31 includes a passage between the clean water tank 5 and the electric water pump 2, and the second passage 32 includes a passage between the clean water tank 5 and the domestic water pump 1. The second electric three-way ball valve 4 includes a third passage 41 and a fourth passage 42. The third passage 41 includes a passage between the electric water pump 2 and the water-using equipment 6, and the fourth passage 42 includes a passage between the electric water pump 2 and the clean water tank 5. The first passage 31 and the third passage 41 are simultaneously connected, and the second passage 32 and the fourth passage 42 are simultaneously connected. The first passage 31 and the second passage 32 are not simultaneously connected, and the third passage 41 and the fourth passage 42 are simultaneously connected.

[0035] The passage can be formed by any two pipe interfaces of the three-way ball valve. The first passage 31 can be understood as the passage between the clean water tank 5 and the electric water pump 2 connected to the first electric three-way ball valve 3, allowing water to be supplied from the clean water tank 5 to the electric water pump 2 through the first passage 31. The second passage 32 can be understood as the passage between the clean water tank 5 and the domestic water pump 1 connected to the first electric three-way ball valve 3, allowing water to be supplied from the clean water tank 5 to the domestic water pump 1 through the first passage 31. The third passage 41 can be understood as the passage between the electric water pump 2 and the water-using equipment 6 connected to the second electric three-way ball valve 4, allowing water to be supplied from the electric water pump 2 to the water-using equipment 6 through the third passage 41. The fourth passage 42 can be understood as the passage between the electric water pump 2 and the clean water tank 5 connected to the second electric three-way ball valve 4, allowing water to be supplied from the electric water pump 2 to the clean water tank 5 through the fourth passage 42.

[0036] For example, such as Figure 2 As shown, the three-way ball valve 1 includes three pipe interfaces: A, B, and C. The passage formed by pipe interfaces A and B of the three-way ball valve 1 is designated as the first passage 31, and the passage formed by pipe interfaces A and C of the three-way ball valve 1 is designated as the second passage 32. Similarly, the three-way ball valve 2 includes three pipe interfaces: A, B, and C. The passage formed by pipe interfaces A and B of the three-way ball valve 2 is designated as the third passage 41, and the passage formed by pipe interfaces A and C of the three-way ball valve 2 is designated as the fourth passage 42.

[0037] Figure 3 This is a structural schematic diagram of a path control module provided by this utility model. This embodiment focuses on the path control module in the above embodiment. Figure 3 As shown, the access control module includes: a central control panel 81;

[0038] The central control panel 81 includes an emergency water supply switch 811;

[0039] The emergency water supply switch 811 is used to control the working state of the water pump control system. The working state includes the default state and the emergency water supply state. In the default state, the second passage 32 of the first electric three-way ball valve 3 and the fourth passage 42 of the second electric three-way ball valve 4 are connected. In the emergency water supply state, the first passage 31 of the first electric three-way ball valve 3 and the third passage 41 of the second electric three-way ball valve 4 are connected.

[0040] The central control panel 81 can be a display for controlling the motorhome system. Various devices on the motorhome can be controlled on the central control panel 81, such as switching the water supply mode of the motorhome's water supply equipment 6. The emergency water supply switch 811 can be understood as a switch on the central control panel used to switch the water supply mode of the motorhome. The emergency water supply switch 811 can be activated in case of a failure of the domestic water pump 1 to ensure that the water supply equipment 6 can be used normally.

[0041] In this embodiment, the operating states of the water pump control system include a default state and an emergency water supply state. The default state is when all devices in the water pump control system are working normally, and water is supplied to the water-using equipment 6 by the domestic water pump 1. The emergency water supply state occurs when the domestic water pump 1 malfunctions and cannot continue to supply water to the water-using equipment 6. Therefore, the emergency water supply switch 811 is turned on, and water can be supplied to the water-using equipment 6 by the electric water pump 2.

[0042] For example, such as Figure 2 As shown, when the water pump control system is in the default state, the second passage 32 of the first electric three-way ball valve 3 and the fourth passage 42 of the second electric three-way ball valve 4 are connected. That is, the passage AC formed by the pipe interface A and the pipe interface C of the three-way ball valve 1 is connected, and the passage AC formed by the pipe interface A and the pipe interface C of the three-way ball valve 2 is connected. Therefore, the electric water inlet 7 can supply water to the clean water tank 5 through the passage AC of the electric water pump M2 and the three-way ball valve 2, and the clean water tank 5 can supply water to the water-using equipment 6 through the passage AC of the three-way ball valve 1 and the domestic water pump M1.

[0043] When the water pump control system is in emergency water supply mode, the first passage 31 of the first electric three-way ball valve 3 and the third passage 41 of the second electric three-way ball valve 4 are connected. That is, the passage AB formed by the pipe interface A and the pipe interface B of the three-way ball valve 1 are connected, and the passage AB formed by the pipe interface A and the pipe interface B of the three-way ball valve 2 are connected. Therefore, the clear water tank 5 can supply water to the water-using equipment 6 in sequence through the passage AB of the three-way ball valve 1, the electric water pump M2, and the passage AB of the three-way ball valve 2.

[0044] In addition, in emergency water supply mode, if the electric water inlet 7 is working, water can also be supplied to the water-using equipment 6 through the passage AB of the electric water pump M2 and the three-way ball valve 2.

[0045] Optionally, the access control module also includes: a smart power distribution box 82;

[0046] The intelligent power distribution box 82 is connected to the central control panel 81;

[0047] The central control panel 81 integrates a control unit 812, which is used to respond to the operation of the emergency water supply switch 811 received on the central control panel 81 and control the intelligent power distribution box 82 to supply power to the domestic water pump 1, the electric water pump 2, the first electric three-way ball valve 3 and the second electric three-way ball valve 4.

[0048] The intelligent power distribution box 82 can be understood as a device for supplying power to electrically driven equipment in the water pump control system, including: a domestic water pump 1, an electric water filling pump 2, a first electric three-way ball valve 3, and a second electric three-way ball valve 4. The intelligent power distribution box 82 can control the operation of the domestic water pump 1 and the electric water filling pump 2, and can also control the continuity of the passages of the first electric three-way ball valve 3 and the second electric three-way ball valve 4. The control unit 812 can be understood as a computing unit integrated on the central control panel 81, which can be used to respond to operations received by the central control panel 81.

[0049] In this embodiment, when the domestic water pump 1 malfunctions, the emergency water supply switch 811 can be turned on the central control panel 81. The control unit 812 can then respond to the opening operation of the emergency water supply switch 811 and send the response result to the intelligent power distribution box 82. The intelligent power distribution box 82 can then supply power to the first electric three-way ball valve 3 and the second electric three-way ball valve 4, and control the first passage 31 of the first electric three-way ball valve 3 and the third passage 41 of the second electric three-way ball valve 4 to be open.

[0050] For example, Figure 4 This is a structural schematic diagram of a centralized control panel connection method provided by this utility model. For example... Figure 4 As shown, the MCU is the control unit 812 integrated on the central control panel 81. The central control panel 81, the control unit 812, and the intelligent power distribution box 82 are connected via the CAN bus. The intelligent power distribution box 82 is connected to the domestic water pump M1, the electric water pump M2, the three-way ball valve 1, and the three-way ball valve 2.

[0051] Optionally, in the default state, the intelligent power distribution box 82 supplies power to the domestic water pump 1, the electric water pump 2, the first electric three-way ball valve 3, and controls the second passage 32 of the first electric three-way ball valve 3 to be open; the intelligent power distribution box 82 supplies power to the second electric three-way ball valve 4, and controls the fourth passage 42 of the second electric three-way ball valve 4 to be open.

[0052] For example, such as Figure 4 As shown, the intelligent power distribution box 82 supplies power to the domestic water pump M1, the electric water filling pump M1, the three-way ball valve 1, and the three-way ball valve 2. In the default state, the intelligent power distribution box 82 controls the domestic water pump M1 to operate normally and controls the AC path of the three-way ball valve 1 to be open. When the electric water inlet 7 is working, the intelligent power distribution box 82 controls the electric water filling pump M2 to operate and controls the AC path of the three-way ball valve 2 to be open.

[0053] Optionally, in emergency water supply mode, the intelligent power distribution box 82 supplies power to the electric water pump 2, supplies power to the first electric three-way ball valve 3, and controls the first passage 31 of the first electric three-way ball valve 3 to be open, and supplies power to the second electric three-way ball valve 4, and controls the third passage 41 of the second electric three-way ball valve 4 to be open.

[0054] For example, such as Figure 4 As shown, the intelligent power distribution box 82 supplies power to the electric water pump M1, the three-way ball valve 1, and the three-way ball valve 2. In emergency water supply mode, the intelligent power distribution box 82 controls the flow of the three-way ball valve 1 through path AB, controls the flow of the three-way ball valve 2 through path AB, and controls the operation of the electric water pump M2.

[0055] The technical solution of this utility model embodiment provides a channel control module, including: a central control panel, which includes an emergency water supply switch. The emergency water supply switch controls the operating state of the water pump control system, enabling one-button switching of the operating state, improving operational convenience and enhancing user experience. The operating states include a default state and an emergency water supply state. In the default state, the second channel of the first electric three-way ball valve and the fourth channel of the second electric three-way ball valve are connected. In the emergency water supply state, the first channel of the first electric three-way ball valve and the third channel of the second electric three-way ball valve are connected. When switching between different operating states, the intelligent power distribution box connected to the central control panel can switch the channels of the first and second electric three-way ball valves, allowing the electric water pump to continue supplying water to the water-using equipment and ensuring its normal operation.

[0056] Figure 5 This is a schematic diagram of a water pump control system in a default state according to the present invention. This embodiment is an elaboration of the above embodiment. Figure 5 As shown, in the default state, the electric water inlet 7 supplies water to the electric water pump 2, the electric water pump 2 supplies water to the clean water tank 5 through the second electric three-way ball valve 4, the clean water tank 5 supplies water to the domestic water pump 1 through the first electric three-way ball valve 3, and the domestic water pump 1 supplies water to the water-using equipment 6.

[0057] In this embodiment, under default conditions, both the domestic water pump 1 and the electric water filling pump 2 operate normally, and both the first electric three-way ball valve 3 and the second electric three-way ball valve 4 are in their default states. Water from the clean water tank is supplied to the domestic water pump 1 via the first electric three-way ball valve 3, and then the domestic water pump 1 supplies water to the water-using equipment 6. When the electric water supply port 7 is operating, water is supplied to the electric water filling pump 2 via the electric water supply port 7, and then the electric water filling pump 2 supplies water to the clean water tank via the second electric three-way ball valve 4.

[0058] Optionally, the electric water pump 2 supplies water to the clean water tank 5 through the fourth passage 42 of the second electric three-way ball valve 4, and the clean water tank 5 supplies water to the domestic water pump 1 through the second passage 32 of the first electric three-way ball valve 3.

[0059] In this embodiment, under default conditions, the intelligent power distribution box 82 controls the second passage 32 of the first electric three-way ball valve 3 to be open, so the clean water tank 5 can supply water to the domestic water pump 1 through the second passage 32 of the first electric three-way ball valve 3. Under default conditions, when the electric water supply port 7 is working, the intelligent power distribution box 82 controls the fourth passage 42 of the second electric three-way ball valve 4 to be open, so the electric water pump 2 can supply water to the clean water tank 5 through the fourth passage 42 of the second electric three-way ball valve 4.

[0060] The technical solution of this utility model embodiment refines the operation of the water pump control system. In the default state, the electric water inlet supplies water to the electric water pump, which in turn supplies water to the clean water tank via a second electric three-way ball valve. The clean water tank then supplies water to the domestic water pump via a first electric three-way ball valve, and the domestic water pump supplies water to the water-using equipment. In the default state, all devices in the water pump control system operate normally, with the domestic water pump supplying water to the water-using equipment. In emergency water supply conditions, the electric water pump can supply water to the water-using equipment, effectively using it as a backup pump for the domestic water pump. This extends the service life of the domestic water pump without affecting the user experience.

[0061] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0062] In one embodiment, under emergency water supply conditions, the clean water tank 5 supplies water to the electric water pump 2 through the first passage 31 of the first electric three-way ball valve 3, and the electric water pump 2 supplies water to the water-using equipment 6 through the third passage 41 of the second electric three-way ball valve 4.

[0063] In this embodiment, during emergency water supply, the domestic water pump 1 malfunctions and cannot operate normally, while the electric water pump 2 can operate normally. At this time, when the emergency water supply switch 811 is activated, the intelligent power distribution box 82 changes the conductive paths in the first electric three-way ball valve 3 and the second electric three-way ball valve 4. This means that the second path 32 of the first electric three-way ball valve 3 is deactivated, while the first path 31 is activated; conversely, the fourth path 42 of the second electric three-way ball valve 4 is deactivated, while the third path 41 is activated. Therefore, the clean water tank 5 supplies water to the electric water pump 2 through the first path 31 of the first electric three-way ball valve 3, and the electric water pump 2 supplies water to the water-using equipment 6 through the third path 41 of the second electric three-way ball valve 4.

[0064] In one embodiment, the water pump control system further includes: an electric water inlet switch 9;

[0065] The electric water inlet switch 9 is used to control the state of the electric water inlet 7;

[0066] The status of the electric water inlet 7 is displayed by the electric water inlet switch indicator light 91. The electric water inlet switch indicator light 91 is connected to the intelligent power distribution box 82. When the electric water inlet switch indicator light 91 is lit, it indicates that the electric water inlet 7 is in the open state. When the electric water inlet switch indicator light 91 is not lit, it indicates that the electric water inlet 7 is in the closed state.

[0067] The electric water inlet switch 9 can be understood as a device used to control whether the electric water inlet 7 is working. The electric water inlet switch indicator light 91 can be understood as a device used to indicate the working status of the electric water inlet 7.

[0068] In this embodiment, Figure 6 This is a structural schematic diagram of an electric water inlet provided by this utility model. (See diagram below.) Figure 6 As shown, the electric water inlet switch 9 is connected to the central control panel 81, which can control the state of the electric water inlet switch 9. The electric water inlet switch indicator light 91 is connected to the intelligent power distribution box 82, so the intelligent power distribution box 82 can respond to the operation of the electric water inlet switch 9 by the central control panel 81, thereby controlling the state of the electric water inlet switch indicator light 91. When the electric water inlet switch indicator light 91 is lit, it indicates that the electric water inlet 7 is in the open state; when the electric water inlet switch indicator light 91 is not lit, it indicates that the electric water inlet 7 is in the closed state.

[0069] For example, such as Figure 4 As shown, the electric water inlet switch 9 is connected to the MCU and the central control panel 81 via the CAN bus, while the electric water inlet switch indicator light 91 is connected to the intelligent power distribution box 82. Therefore, when the electric water inlet switch 9 is opened on the central control panel 81, the MCU processes the operation and sends the processing result to the intelligent power distribution box 82, which then supplies power to the electric water inlet switch indicator light 91, causing it to light up.

[0070] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
