Description

Intelligent water dispenser

Technical Field

The invention relates to the technical field of water dispensers, in particular to an intelligent water dispenser.

Background

The prior water dispenser, especially the public water dispenser, is easy to be polluted, difficult to maintain, free of convenient and complete supervision and remote supervision, reasonably encourages to reduce the waste of the rubber bottle, is humanized to clean and save energy, provides the water temperature of cool mouthfeel, and copes with frequent dosage to balance the fineness and the volume of the water dispenser.

Specifically, 1, the water outlet of the water dispenser in the prior art is exposed outside, so the water outlet is easily polluted; 2. the prior art water dispenser is difficult to disassemble and assemble, and parts are difficult to maintain and replace, particularly a refrigeration system is mostly disassembled and maintained; 3. the prior art water dispenser does not have a self-monitoring system, and the following conditions exist:

a. self-monitoring of filter element: generally, a water dispenser supplier only requires a user to replace the filter element regularly. But each cartridge has a limited amount of its water capacity. If the dosage is larger than the limited quantity of the filter element, the water quality is not ensured; b. the flow is low: when the filter element is clogged or the water supply is in problem, the manager of the water dispenser can not know and can not follow up the water supply in the most proper time. The flow rate is very slow or no water is discharged when the user adds water, so that the experience of the user is very poor; c. and (3) continuous water discharge: when a user improperly uses the water dispenser, such as washing hands, or the water dispenser is damaged by pressing, the water dispenser has the opportunity to stop discharging water. Not only can the food water be wasted and the service life of the filter element be prolonged, but also the water can be soaked or leaked on the ground; d. water temperature: the temperature of the water entering the water dispenser cannot be detected, so that the effect of a refrigeration system and the feeling of a user cannot be well controlled and monitored; e. water level monitoring sensor and water leakage monitoring sensor: the general drinking machine does not monitor whether the water outlet tray is full of water or not, or the inside of the water outlet tray has water leakage, so that the water immersion on the ground is unknown; f. temperature > 38 ℃: typically, activated carbon filter elements have a recommended maximum operating temperature. If the temperature of the inlet water is higher than the upper temperature limit, the active carbon filter element is damaged or the filtering performance is reduced; g. electrifying: when power failure occurs or the power supply of the water dispenser is interrupted, the water dispenser cannot operate, and a manager often cannot know the failure and finds the failure later, so that a user cannot use the water dispenser; h. automatic flushing: when the using amount is sparse or idle, water in the water machine is kept for too long, and bacteria are easy to breed. Some drinking water dispensers have an automatic flushing function, but only twice at most. Under the state of long-time non-use at night, the two-time washing can not effectively prevent bacteria from breeding in the drinking machine; i. setting parameters: most of the water dispensers have few functions and do not need to be set. Some water machines have some functions, can make some settings, but can not record the setting update. There are situations where settings are changed and the administrator is not aware of it; j. wireless supervision: the general water machine can not allow a manager to effectively monitor the use and operation conditions of the water machine, so that the user is not full and is not aware of delayed maintenance. Moreover, the responsibility falls on the site manager, and the workload of the site manager is increased; k. the water machine uses data which are not recorded and monitored by the common water machine.

4. At present, various societies encourage the reduction of waste in rubber bottles and advocate environmental protection. The existing plastic wastes are excessive, so that great environmental and ecological problems are caused. Each community encourages citizens to carry water goblets by themselves, reduces the purchase of bottled water and reduces waste from the source.

The prior art water dispensers rarely have the function of encouraging users to add water, and some are generally encouraged to reduce the display of glue bottles by adding water by using the water dispensers, and the water dispensers are generally counted by taking 500ml as one glue bottle. However, this calculation is not accurate enough and encourages a lack of specificity. If the water adding amount of the user is small, bottle saving numbers do not rise, and no encouraging effect is achieved; if the water adding amount of the user is large, the number of the bottles is saved by one-time use but is increased by a plurality of times, which is not consistent with the reality. The size of the glue bottle is large or small, so that one glue bottle is saved when the water is added to the water dispenser at one time, and encouragement is required.

5. The cold water supply of the water dispenser refrigeration system is determined according to the size of the cold water tank, the size of the cold water tank influences the refrigeration speed or time and the sizes of other refrigeration related parts, and the size of the refrigeration system is generally the biggest key of the size and the cost of the whole water dispenser. However, the cold water of the common water dispenser is directly led out from the cold water cylinder, so that the cold water can be used up quickly when the consumption is large. The problem that water cannot be supplied in time is particularly serious for public drinking water machines.

6. LCD, speaker, camera aspect: the prior art water dispenser only has a water adding function, so that the prior art water dispenser cannot interact with a user or provide an audio-visual function, and the use experience is not good.

7. And (3) pause notification: when the state or use of the water dispenser or the filter element is in a problem, the water dispenser in the prior art still allows a user to add water, so that the water quality cannot be ensured, problems can be caused to the field, and even danger is caused to surrounding people.

8. Energy conservation: refrigeration is the most power-consuming function of the water dispenser, and generally, the water dispenser is only used for starting a refrigeration system by the water temperature in a cold water cylinder, which is the same in any case, although when no one or few people use the water dispenser, or the water is cold in winter, the energy is wasted.

The above-mentioned drawbacks are worth solving.
