The operation principle of the water outlet assembly will be described in detail with reference to fig. 3 to 6 by taking a refrigerator having a water dispenser comprising the water outlet assembly as an example.
As shown in fig. 3, the water outlet assembly is fixed to the inner side of a door 120 of a refrigerating chamber of a refrigerator through a fixing bracket 109, and a water dispenser shelf 130 for installing a water tank 140 of a water dispenser is provided at the upper part of the water outlet assembly; a compression bar 110 is provided on the fixing bracket 109, and the compression bar 110 is positioned at the outer side of the door 120 of the refrigerator refrigerating chamber, so that a user can conveniently take water. Specifically, as shown in fig. 4, after the door 120 of the refrigerator refrigerating chamber is provided with the water intake groove 160, the fixing support 109 is connected with the water intake groove 160, and the compression bar 110 is located in the water intake groove 160 and is communicated with the outside of the refrigerator, and the fixing support 109 and the water intake groove 160 are sealed by adopting a sealing material, so as to prevent the cold in the refrigerator refrigerating chamber from leaking to the outside of the refrigerator, thereby causing excessive energy loss of the refrigerator. The water in the water tank of the water drinking device is cooled by the cold energy generated by the refrigerating chamber of the refrigerator, so that a user can take out cold water from the water drinking device. Therefore, the water drinking device and the refrigerator are combined together, not only can the aim of saving energy be achieved, but also the requirement of a user on cold water can be met.
As shown in fig. 5, the water outlet assembly is clamped at the middle lower part of the fixing bracket 109, the lower surface 1080 of the top of the water outlet nozzle of the water outlet assembly is contacted with the convex part 1101 on the pressure lever 110, and the water taking process of the user is completed by controlling the angle change of the pressure lever 110. When a user takes water (the water outlet assembly is in an open state), the water cup is contacted with the pressing rod 110, so that a moving part consisting of the water outlet nozzle 108, the second sealing part 107, the second valve core 106, the third sealing part 103, the first valve core 102 and the first sealing part 101 moves upwards, at this time, not only the elastic part 105 on the first valve core 102 is compressed and deformed, but also the first sealing part 101 connected with the connecting part 1063 of the second valve core 106 is separated from a hole on the bottom of the fourth groove 1040 of the valve body bracket 104, so that the first water outlet channel 301 is formed. In this way, water in the water tank of the water fountain can flow through the gap between the first valve core 102 and the valve body bracket 104 through the first water outlet channel 301, and flow to the water outlet nozzle 108 through the plurality of water outlets on the second valve core 106, and flow from the water outlet nozzle 108 into the cup.
When the user finishes taking water (taking out the required water amount), the water cup is moved away from the pressure lever 110 (the water outlet assembly is switched from the open state to the closed state), and the elastic member 105 in the water outlet assembly is restored to the initial state (the state when not compressed) from the compressed state, so that the moving member consisting of the water outlet nozzle 108, the second sealing member 107, the second valve core 106, the third sealing member 103, the first valve core 102 and the first sealing member 101 is driven to move downwards. In this process, as shown in fig. 6, first, the first sealing member 101 covers the hole on the bottom of the fourth recess 1040 of the valve body bracket 104, so that the first water outlet channel 301 is sealed, and at this time, the water in the water tank of the water fountain cannot flow into the gap between the first valve core 102 and the valve body bracket 104 any more. However, due to gravity, water that has flowed through the first outlet passage 301 continues to flow downward and toward the spout 108 through the plurality of water outlets on the second cartridge 106. Since the third sealing member 103 contacts the bottom of the second groove 1060 of the second valve core 106, at this time, as shown in fig. 6, the lower portion of the sliding member 1043 is spliced with the sidewall of the second groove 1060 of the second valve core 106, so that a first negative pressure is formed in the gap between the first valve core 102 and the valve core bracket 104, and water can be ensured to be absorbed in the gap between the first valve core 102 and the valve core bracket 104 under the action of the negative pressure, so that water in the gap between the first valve core 102 and the valve core bracket 104 cannot flow into the second valve core 106. Meanwhile, under the action of the water film 502 formed between the sliding member 1043 and the second groove 1060, a differential pressure space 504 (as shown in fig. 6) with a second negative pressure is further formed between the sliding member 1043 and the second groove 1060, where the differential pressure space 504 is a space that can be formed only when the cup is removed from the compression bar 110 after the user finishes taking water, and the second negative pressure in the differential pressure space 504 can be used to suck the water remaining in the water outlet 108 from the multiple water outlets of the second valve core 106 into the differential pressure space 504, and since the multiple water outlets of the second valve core 106 also have a certain resistance to the water in the differential pressure space 504, the water can be retained in the differential pressure space 504 for a long time, so that the problem of hidden water leakage hidden danger of the water outlet of the existing water drinking device is solved.
According to the water outlet assembly provided by the utility model, on one hand, the elastic piece in the valve core assembly is controlled to be in a compressed state to form the first water outlet channel, so that the water taking process is completed. On the other hand, the time difference in the process that the elastic piece in the valve core assembly is restored to the initial state from the compressed state is utilized to form a double-sealing intercepting structure, a first negative pressure is formed in a gap between the valve core assembly and the valve body support in sequence, a differential pressure space with a second negative pressure is formed between the valve core assembly and the valve body support, double water locking of the water outlet assembly is realized through the double negative pressures, residual water in the water outlet assembly is ensured to be locked in the water outlet assembly, and therefore the problems of water leakage and hidden danger of water dripping existing in the existing water drinking device are solved.
The water leakage-proof water outlet assembly, the water drinking device and the refrigerator comprising the water leakage-proof water outlet assembly are described in detail above. Any obvious modifications thereof, which would be apparent to those skilled in the art without departing from the true spirit of the present utility model, would fall within the scope of the present patent claims.
