Description

REFRIGERATOR WATER SUPPLY SYSTEM AND REFRIGERATOR HAVING THE
SAME
FIELD OF THE INVENTION
The present invention relates to a refrigerator water supply system, especially to a refrigerator water supply system in which two control valves are provided in series on each single-way water path, and to a refrigerator having the water supply system. BACKGROUND ART
With technology improvement, a refrigerator equipped with a water system comes on the market, wherein the water system can supply directly pure water, drink, cold and hot water or ice cubes to suffice various requirements of a user. For example, common water systems include an ice production system and a cool water system. In the water system of the refrigerator, it is common that a water inlet pipe is connected with a water supply system, water supply pipes of the water supply system are connected with the ice production system and the cool water system, and one control valve is mounted on the respective water supply pipes leading to the ice production system and the cool water system in order to control opening and closing of the respective water supply pipes. When a user selects ice production or cool water by a control device, the control device can control opening and closing of the water supply pipe by controlling the control valve in the relevant water supply pipe. In the water supply pipe, a throttle valve can be provided to control closing of a water path, and if particles are not filtered out and thus are contained in water flowing through the throttle valve, a piston in the throttle valve may be clamped so as to be unable to close the water path, this leads to unstoppable water spillage and inconvenience for a user. SUMMARY OF THE INVENTION
An object of the present invention is to provide a refrigerator water supply system to improve the reliability of closing of the refrigerator water supply system. Another object of the present invention is to provide a refrigerator having the above refrigerator water supply system, in which water spillage can be avoided and thus the usage safety of the refrigerator can be improved.
The present invention provides a refrigerator water supply system, comprising a water supply pipe inlet, at least one water supply pipe outlet, at least one water supply pipe connecting the water supply pipe inlet with the at least one water supply pipe outlet, and a water supply controller. At least two control valves are provided in series on at least one water supply pipe, and a control signal outputted from the water supply controller is used to control the respective control valves on one water supply pipe simultaneously.
By providing at least two control valves in each water supply pipe in series and by a control signal outputted from the water supply controller being used to control the respective control valves on one water supply pipe simultaneously, it is ensured that even if one control valve in the water supply pipe can not be closed, another normally working control valve can still ensure normal closing and opening of the water path, thus, avoiding unstoppable water spillage due to failing closing of the control valve in the case of only one control valve in the respective water supply pipes.
In a further exemplary embodiment of a refrigerator water system, the refrigerator water system comprises two water supply pipe outlets and two water supply pipes connected with the two water supply pipe outlet respectively, and the water supply controller may selectively output a control signal to the control valves on the two water supply pipes. In addition, the two control valves in each water supply pipe each are a throughway valve, or one of the two control valves is an angle throttle valve and the other is a throughway valve, to reduce volume of the refrigerator water supply system and make fitting easy.
The present invention provides also a refrigerator having the inventive refrigerator water supply system.
In an exemplary embodiment of the refrigerator, the water system has two water supply pipes, the control valves on each water supply pipe each are a throughway throttle valve, and the two water supply pipes are fixed vertically in the refrigerator via a bracket. When the control valves on the two water supply pipes each are a throughway throttle valve and the two water supply pipes are fixed in the refrigerator by a metal plate, water flow flowing in a horizontal direction can be avoided, thus water leakage upon flowing through the water system may be avoided.
In the above refrigerator water system, usage safety of the refrigerator can be improved further, thus avoiding unstoppable water spillage due to failing closing of the control valve in the case of only one control valve in the respective water supply pipes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION In order to better understand technical features, objects and effects of the present invention, embodiments of the invention are described hereinafter with reference to the drawings. In the respective figures, the same reference numeral designates the same part. Fig. 1 is a schematic view of one exemplary embodiment of a refrigerator water supply system. As shown in the figure, the refrigerator water supply system 100 comprises a water supply pipe 110 and a water supply controller 120, and two control valves 116 and 118 are provided in series between a water supply pipe inlet 1 12 and a water supply pipe outlet 1 14 of the water supply pipe 1 10. In the embodiment shown, the two control valves 116 and 118 are a throughway valve. A control signal from the water supply controller 120 can be used to control opening or closing of the two throughway valves simultaneously, thereby reducing a risk of unstoppable water outflow as a certain control valve can not be closed, and improving work stability of the water supply system. Fig. 2 is a schematic view of another exemplary embodiment of a refrigerator water supply system. As shown in the figure, the refrigerator water supply system 200 comprises a water supply pipe inlet 212 and two water supply pipe outlets 214. For example, one water supply pipe outlet 214 may be connected with an ice production system, while the other water supply pipe outlet 214 may be connected with a cool water system, thus, different requirements of a user can be sufficed. Two water supply pipes 210 connect the water supply pipe inlet 212 with the water supply pipe outlets 214 respectively. Two control valves 216 and 218 are provided in series on each water supply pipe 210. In the embodiment shown in Fig. 2, one control valve 216 is a throughway valve and the other control valve 218 is an angle valve. A water supply controller 220 may control the control valves on the two water supply pipe 210 by two control signals respectively, and each control signal may used to control simultaneous opening or closing of the two control valves 216 and 218 on the respective water supply pipe 210.
Fig. 3 is a structural schematic view of the refrigerator water supply system shown in Fig. 2. The refrigerator water supply system comprises one water supply pipe inlet 212 and two water supply pipe outlets 214. For example, one water supply pipe outlet 214 may be connected with the ice production system, while the other water supply pipe outlet 214 may be connected with the cool water system, thus, different requirements of a user can be sufficed. Two water supply pipes 210 connect the water supply pipe inlet 212 and the water supply pipe outlets 214 respectively. A throughway throttle valve 216 and an angle throttle valve 218 are connected on each water supply pipe 210, and have control parts connected with the water supply controller (not shown in Fig. 3). In the embodiment shown in Fig. 3, the throughway throttle valves 216 are connected at positions adjacent to the water supply pipe inlet 212 by screw thread, and the angle throttle valves 218 are connected at corners of the water supply pipe 210 by screw thread. With this structure, a mounting space required by the water supply system can be reduced and a compact and convenient arrangement may be achieved. Of course, according to different design requirements, the throughway throttle valves and the angle throttle valves may also be mounted at other positions of the water supply pipe 210, employ other connection ways, and are not limited to the structure and form shown in Fig. 3. A shape of the water supply pipe is not limited to the shape shown in the figure, and the throughway valves and the angle valves on the respective water supply pipes may be other types of the throughway valves and the angle valves.
According to different design requirements, other types of control valves may also be used in the water supply pipe, and a number of the control valves may also be greater than two. According to different design requirements, a plurality of water supply pipes having the above structure and connected with a water inlet pipe can be provided, and the control valves can receive different control signals for different water supply pipes. Fig. 4 is a schematic view of a further exemplary embodiment of a refrigerator water supply system. As shown in the figure, the refrigerator water supply system 300 comprises a water supply pipe inlet 312 and two water supply pipe outlets 314. For example, one water supply pipe outlet 314 may be connected with an ice production system, while the other water supply pipe outlet 314 may be connected with a cool water system, thus, different requirements of a user can be sufficed. Two water supply pipes 310 connect the water supply pipe inlet 312 and the water supply pipe outlets 314 respectively. Two control valves 316 and 318 are provided in series on each water supply pipe 310. In the embodiment shown in the figure, the control valves 316 and 318 are a throughway valve. A water supply controller 320 can control the control valves on the respective water supply pipes 310 by two control signals respectively, and each control signal may be used to control simultaneous opening or closing of the two control valves 316 and 318 on the relevant water supply pipe 310. According to different design requirements, other types of control valves may also be used in the water supply pipe, and a number of the control valves may also be greater than two.
According to different design requirements, a plurality of water supply pipes having the above structure and connected with a water inlet pipe can be provided, and the control valves can receive different control signals for different water supply pipes.
Fig. 5 is a schematic view when the refrigerator water supply system shown in Fig. 4 is used. In a practical use of the refrigerator water supply system 300, a bracket may be fixed at a mounting position of the water supply system 300 in a refrigerator 400, and two water supply pipes 310 is fixed vertically on the bracket 330, as a result, the water supply system 300 may be connected stably to the refrigerator. Due to vertical arrangement of the water supply pipes 310, a problem may be avoided in that leakage occurs due to poor sealing when a water flow flowing through the water supply system flow in a horizontal direction.
According to different design requirements, other forms and structures are conceivable to fix the water supply pipes of the refrigerator water system in the refrigerator vertically, but not limited to the structure and form shown in the figure. In the refrigerator having the inventive refrigerator water supply system, a problem may be avoided in that in the case of only one control valve in each water supply pipe, unstoppable water spillage occurs due to failing closing of the control valve, thus, a safety is improved.
In the context, the expression "exemplary" represents "acting as an example, an instance or for explanation", thus, any illustrations and embodiments described as "exemplary" in this context should be not interpreted as a more preferable or more beneficial technical solution.
The above description is merely to describe practicable embodiments of the present invention, and is not used to limit the scope of protection of the present invention. Any changes and modifications made without departing from the spirit of the present invention fall within the scope of the present invention.
