The long-time backflow of the condensed water can cause the water tank to overflow, so a drainage structure needs to be arranged in the drinking water equipment, but the drainage structure needs to guide water from the inside of the drinking water equipment to the outside, and the design difficulty and the complexity of the structure of the drinking water equipment are increased.

Therefore, the embodiment of the invention provides a drinking device, which can solve the problem of condensed water discharge of a cold storage water tank, does not need to be provided with a discharge structure, simplifies the structural design of the drinking device and enables the appearance of the drinking device to be kept complete.

When the water in the water tank 10 is accumulated more, the water in the water tank 10 needs to be discharged. The water tank 10 in this embodiment is provided with an overflow 11, and the overflow 11 is located at an upper portion of the water tank 10 at a position close to an opening of the water tank 10. When the water in the tank 10 accumulates to this position, the water in the tank 10 is discharged from the overflow 11, preventing the water from flowing around the opening of the tank 10 to various positions of the housing.

In one embodiment, the evaporation cartridge 20 is located below the water tank 10, the overflow 11 is located above the evaporation cartridge 20, and the normal opening of the evaporation cartridge 20 faces the overflow 11 and the water tank 10, so that the water flowing out of the overflow 11 directly falls into the evaporation cartridge 20, and the condensed water generated on the outside of the water tank 10 can also be left in the evaporation cartridge 20 along the water tank 10, thereby collecting all the condensed water generated in the water tank 10. Alternatively, in another embodiment, a connection pipe 40 is provided between the overflow 11 and the evaporation cartridge 20, and the water flowing out of the overflow 11 passes through the connection pipe 40 and is discharged into the evaporation cartridge 20. Or, in still other embodiments, the evaporation cartridge 20 is positioned below the water tank 10, the overflow 11 is positioned above the evaporation cartridge 20, the evaporation cartridge 20 is normally open toward the overflow 11, and the water tank 10 is provided with a connection pipe 40 between the overflow 11 and the evaporation cartridge 20. In this way, the water flowing out of the overflow hole 11 is discharged into the evaporation box 20 through the connection pipe 40, and the condensed water generated on the outside of the water tank 10 is also allowed to flow down along the water tank 10 into the evaporation box 20, thereby collecting all the condensed water generated in the water tank 10.

That is, in this embodiment, after the condensed water generated by the water tank 10 is discharged to the evaporation box 20, the evaporation box 20 is heated by the first heat exchanging portion 30, so that the water in the evaporation box 20 becomes water vapor, and as the air is discharged, a drainage structure introduced outside the housing does not need to be additionally arranged, so that the arrangement of the drainage structure can be omitted, the internal structure of the drinking water equipment is simplified, and the structural complexity of the drinking water equipment is reduced.

The refrigerant discharged from the compressor 50 passes through the first heat exchanging portion 30, the first heat exchanging portion 30 exchanges heat at the evaporation box 20 to heat the water in the evaporation box 20, then flows to the second heat exchanging portion through the throttling part, exchanges heat in the second heat exchanging portion, and then flows back to the compressor 50 to form a circulating heat pump heat exchanging system. In this way, the water in the evaporation box 20 is continuously heated until the water in the evaporation box 20 is evaporated.

Alternatively, in some embodiments, the heat exchange system may be a stand-alone heat pump system.

Or, the heat exchange system is a refrigeration system of the water tank 10, that is, the second heat exchange portion is an evaporator, and the second heat exchange portion is disposed in the water tank 10 to provide cold energy to the water tank 10, so that the temperature of water in the water tank 10 is relatively low. That is, in the embodiment, the evaporation box 20 is disposed in the casing, and then the first heat exchanging portion 30 in the refrigeration system is disposed on the evaporation box 20, so that the condensed water can be evaporated into water vapor, which is low in cost and simple in structure.

Alternatively, in an embodiment, the first heat exchanging part 30 may be a condenser 31 of the refrigeration system. That is, the condenser 31 of the refrigeration system is placed in the evaporation box 20 for heating the water in the evaporation box 20.

Alternatively, in another embodiment, referring to fig. 3 and 4, the first heat exchanging part 30 includes a condenser 31 of the refrigeration system, and further includes a coil assembly 32, the coil assembly 32 is connected between an exhaust port of the compressor 50 and the condenser 31, and the coil assembly 32 is disposed in the evaporation box 20. That is, at least one set of coil assembly 32 is further disposed between the condenser 31 of the heat exchange system and the exhaust port of the compressor 50, the coil assembly 32 is disposed in the evaporation box 20, and a high-temperature and high-pressure refrigerant discharged from the exhaust port of the compressor 50 passes through the coil assembly 32, exchanges heat with water in the evaporation box 20 in the coil assembly 32, then flows to the condenser 31, exchanges heat secondarily in the condenser 31, and then enters the evaporator for heat exchange and refrigeration after passing through the throttling component.

In the present embodiment, the coil assembly 32 is disposed between the condenser 31 and the compressor 50 to heat the evaporation box 20, since the coil assembly 32 is a separate heating component, it can be set according to the size and structure of the evaporation box 20, and compared with the embodiment that directly uses the condenser 31 to heat the evaporation box 20, the present embodiment can miniaturize the evaporation box 20 (since the condenser 31 is larger, if the condenser 31 is placed in the evaporation box 20, it is necessary to set the evaporation box 20 with at least the same size).

Alternatively, in some optional embodiments, the heat exchanging part comprises a condenser 31 of the refrigeration system, and further comprises a coil assembly 32, wherein a pipeline between the discharge port of the compressor 50 and the condenser 31 is connected in parallel with the coil assembly 32, and the coil assembly 32 is disposed in the evaporation box 20.

In this embodiment, the coil assembly 32 is connected in parallel to the line between the condenser 31 and the discharge port of the compressor 50. Part of the high-temperature and high-pressure refrigerant discharged from the exhaust port of the compressor 50 passes through the coil assembly 32, exchanges heat with water in the evaporation box 20 in the coil assembly 32, and then flows to the condenser 31; part of the high-temperature and high-pressure refrigerant directly flows to the condenser 31 through the pipeline, and when the refrigerant passing through the coil assembly 32 flows to the condenser 31, the refrigerant is converged with the refrigerant directly flowing to the condenser 31 through the pipeline, and then heat exchange is carried out in the condenser 31; then enters the evaporator for heat exchange and refrigeration after passing through the throttling component.

In this embodiment, the coil assembly 32 is disposed between the compressor 50 and the condenser 31 in parallel, so that a portion of the refrigerant flows to the coil assembly 32, so that the coil assembly 32 heats and evaporates the water in the evaporation box 20. And part of the high-temperature refrigerant and part of the refrigerant which exchanges heat through the coil assembly 32 are mixed in the condenser 31, so that the heat exchange effect of the condenser 31 is improved.

Optionally, based on the above embodiment, in an optional embodiment, a switch valve may be disposed at one end of the coil assembly 32 close to the exhaust port, and when the water in the evaporation box 20 needs to be heated, the switch valve may be controlled to be opened, so that the high-temperature and high-pressure refrigerant discharged from the exhaust port of the compressor 50 enters the coil assembly 32, and the coil assembly 32 is used to heat the water in the evaporation box 20. When the evaporation box 20 has little water or no water, the switch valve is controlled to be closed, so that the high-temperature and high-pressure refrigerant discharged from the exhaust port of the compressor 50 directly flows to the condenser 31 through the pipeline and does not pass through the coil assembly 32, and the evaporation box 20 is prevented from being damaged due to dry burning of the evaporation box 20 by the coil assembly 32.

Alternatively, the switch valve can be opened or closed manually by a person, and can also be opened or closed at set time. Or in order to improve the efficiency of the treatment of the condensed water in the evaporation box 20 and improve the treatment effect, it can be provided that the opening and closing valve is automatically triggered to open or close based on the detection member, such as the following exemplified embodiments:

That is, when the water level detecting member detects a water level signal, the water level signal is sent to the controller, the controller receives the water level information, it is determined that the water in the evaporation box 20 reaches the preset position, at this time, an opening signal is sent to the switch valve to trigger the switch valve to open, a high-temperature and high-pressure refrigerant discharged by the compressor 50 flows into the coil assembly 32 through the switch valve, and the coil assembly 32 is used for heating the water in the evaporation box 20 to evaporate the water into steam and discharge the steam to the outside.

When the water level is lower than the preset position, if the water level detecting member does not detect the water level signal, the switch valve is controlled to be closed to stop heating the evaporation box 20. Or after the water level signal is not detected by the water level detection part and a preset time is up, the switch valve is controlled to be closed, and the evaporation box 20 stops being heated, so that the evaporation box 20 is protected.

Optionally, in order to avoid the coil assembly 32 from shaking to generate noise, at least one fixing rib is disposed on the sidewall of the evaporation box 20 in this embodiment, at least two fixing grooves are formed by the fixing rib and the sidewall of the evaporation box 20, and the coil assembly 32 is installed in the fixing grooves to fix the coil assembly 32.

Optionally, in other embodiments, with continued reference to fig. 1 to 4, the coil assembly 32 may also be disposed between the condenser 31 and the throttling component, and the coil assembly 32 performs a secondary temperature reduction through the water in the evaporation pan to improve the heat exchange efficiency of the heat exchange system. Or, another coil assembly 32 is further disposed between the condenser 31 and the throttling component, and for example, the coil assembly 32 is disposed between the condenser 31 and the compressor 50 and between the condenser 31 and the throttling component, so as to perform secondary cooling on a refrigerant through the coil assembly 32. In the following, a mode and an effect of providing the coil assembly 32 between the condenser 31 and the throttling member and performing secondary cooling on the refrigerant in the coil assembly 32 by using the water in the evaporation pan will be described as an example.

In this embodiment, the drinking device includes a housing, a water tank 10, an evaporation box 20 and a heat exchange system. The water tank 10, the evaporation cartridge 20 and the heat exchange system are disposed in the housing.

Optionally, the water tank 10 is a cold storage water tank 10, the heat exchange system provides cold for the water tank 10, and when a drinking water pipeline of the drinking water device passes through the water tank 10, the drinking water device is refrigerated based on low-temperature water in the water tank 10, so that the temperature of drinking water is reduced.

Optionally, the heat exchange system comprises a compressor 50, a condenser 31, a coil assembly 32, a throttling component and a second heat exchange part which are connected in sequence. The second heat exchanging portion is used for providing cold energy for the water tank 10, the coil assembly 32 is arranged in the evaporation box 20, and water in the evaporation box 20 can exchange heat with the coil assembly 32.

It can be understood that, in the present embodiment, a water outlet is provided on the water tank 10, and the water outlet is communicated with the evaporation box 20 through a connecting pipe 40, so that a part of the water in the water tank 10 can be delivered into the evaporation box 20. Because the temperature of the water in the water tank 10 is lower, the water in the water tank 10 can exchange heat with the coil assembly 32 in the evaporation box 20, so that the temperature of the refrigerant in the coil assembly 32 is reduced, and the secondary cooling of the refrigerant in the coil assembly 32 is realized. If the high-temperature and high-pressure refrigerant discharged from the compressor 50 flows to the coil assembly 32 after being subjected to heat exchange by the condenser 31, the water in the evaporation box 20 secondarily cools the refrigerant in the coil assembly 32 and then flows to the second heat exchanging portion by the throttling part, so that the temperature of the refrigerant in the second heat exchanging portion is lower, the cooling capacity of the second heat exchanging portion is increased, and the second heat exchanging portion can absorb more heat during heat exchange with the water in the water tank 10, thereby improving the cooling capacity of the water tank 10.

In addition, during a cooling process of the water tank 10, condensed water is generated in the tank cover 60 at the inside and the top of the water tank 10 due to factors such as ambient humidity, and the condensed water generated in the tank cover 60 at the inside and the top of the water tank 10 flows back into the water tank 10 due to the structural arrangement of the water tank 10. When the water in the water tank 10 is accumulated more, the water in the water tank 10 needs to be discharged. This embodiment is through the delivery port, regularly with some water in the water tank 10 is taken out in the evaporation box 20, can regularly discharge the water tank 10 outside based on the surplus water of comdenstion water accumulation in the water tank 10, can effectively avoid the water in the water tank 10 to flow out around the opening of water tank 10. The water in the evaporation box 20 can be evaporated into steam because the coil assembly 32 can heat the water in the evaporation box 20, and then the excess condensed water in the water tank 10 is discharged out of the drinking water device through the air. So, this embodiment based on evaporation box 20 with the setting of coil assembly 32 not only can improve drinking water equipment's refrigerating system's refrigeration efficiency, can also effectually with drainage in the water tank 10 is got rid of, saves the setting of outside drainage structure, simplifies the inner structure of water tank 10.

Optionally, the water outlet may be disposed at any position of the water tank 10, and if a valve is disposed on the water outlet, when water needs to be provided into the evaporation box 20, the valve is opened, and water flows into the evaporation box 20 through the connection pipe 40.

Alternatively, in some embodiments, the drinking device may further include a water supply system for supplying water to the evaporation cartridge 20. If the water outlet is higher than the water level in the water tank 10 (the water outlet is set at a higher position, or the water in the water tank 10 is reduced), the water in the water tank 10 is delivered into the evaporation box 20 through the water supply system, so as to meet the water demand in the evaporation box 20.

Optionally, in an embodiment, the water supply system is an independent water supply system of the evaporation cartridge 20. If the water supply system comprises a water suction pump, the water suction pump is connected with the connecting pipe 40 so as to suck water from the water tank 10 to the evaporation box 20 through the connecting pipe 40.

That is, when the water outlet is higher than the water level in the water tank 10, the water in the water tank 10 is pumped into the evaporation box 20 by the power of the water pump, so that the evaporation box 20 cools the coil assembly 32.

Alternatively, in the other embodiment, the water supply system may be the water supply system of the water tank 10, without providing an additional water supply system, thereby reducing the cost and the structural arrangement inside the housing. If the water supply system comprises a water suction pump and a water pipe, the water pipe is connected with a water source and the water tank 10, and the water suction pipe is connected with the water pipe so as to suck water into the water tank 10 through the water pipe. In the present embodiment, the overflow 11 of the water tank 10 is formed by disposing the water outlet at a predetermined position of the upper portion of the water tank 10, at a position close to the opening of the water tank 10. When the water in the water tank 10 is accumulated to the predetermined position, the water is discharged from the overflow opening 11 out of the water tank 10 and then discharged into the evaporation box 20 through the connection pipe 40, so that the water is provided for the evaporation box 20, the water requirement in the evaporation box 20 is ensured, and the water can be prevented from flowing to various positions of the housing around the opening of the water tank 10.

When the evaporation cartridge 20 has a water demand, the water supply system supplies water to the water tank 10 so that the water in the water tank 10 overflows from the overflow opening 11 and is discharged into the evaporation cartridge 20. Thus, the water demand of the evaporation box 20 can be satisfied, and the water tank 10 can be prevented from being drained to cause the water tank 10 to be incapable of cold storage.

The structure of this embodiment sets up for drinking water equipment's refrigeration effect and drainage effect are better.

Optionally, in an embodiment, the drinking device further includes a controller, the controller is connected to the water supply system, and the controller controls the water supply system to supply water to the evaporation box 20. The water supply system may be periodically or periodically activated by the controller to supply water to the evaporation cartridge 20.

It can be understood that, under normal atmospheric temperature environment, the influence that refrigerating system's refrigeration effect received is less, and in order to avoid under normal atmospheric temperature environment, still need the comdenstion water right refrigerating system carries out the secondary cooling, extravagant water resource. In this embodiment, the water supply system is started only in a high-temperature and high-humidity environment, water is supplied to the evaporation box 20, and the high-temperature refrigerant of the refrigeration system is cooled down secondarily by using low-temperature water. So, can make drinking water equipment realizes low energy consumption high efficiency work.

Optionally, the drinking water equipment further comprises a temperature sensor and a humidity sensor, the temperature sensor and the humidity sensor are both connected with the controller, and the controller is used for controlling the water supply system to supply water to the evaporation box 20 according to the environmental information detected by the temperature sensor and the humidity sensor. The humidity sensor detects the humidity of the environment, and the humidity sensor detects the temperature of the environment. The humidity sensor sends the detected temperature to the controller, the temperature sensor sends the detected humidity to the controller, and the controller determines whether to start a water supply system or not according to the temperature and the humidity and supplies water to the evaporation box 20. And when the temperature is higher than the preset temperature and the humidity is higher than the preset humidity, judging that the drinking equipment refrigerates in a high-temperature high-humidity environment. At this time, the refrigeration effect of the refrigeration system is poor, the water supply system is started to control the water supply system to supply water to the evaporation box 20, and enough water is contained in the evaporation box 20 to cool the coil assembly 32 of the refrigeration system so as to perform secondary cooling on the refrigerant in the refrigeration system, thereby improving the refrigeration effect of the refrigeration system. And when the temperature is less than the preset temperature and/or the humidity is less than the preset humidity, the water drinking device is judged to work under the normal temperature environment, at this moment, the secondary cooling of the refrigerant of the refrigeration system is not needed, the water supply system is not started, and the water storage in the evaporation box 20 is avoided (under the environment, the heat exchange efficiency of the coil assembly 32 of the refrigeration system is also low, the water in the evaporation box 20 is also difficult to evaporate, and therefore the water supply system is not started to supply water into the evaporation box 20 under the condition).

Alternatively, in other embodiments, the water supply system may also be automatically activated based on the amount of water in the evaporation cartridge 20. It should be noted that, the water in the evaporation box 20 is right to the refrigeration system-in system for secondary cooling, and a sufficient amount of water is needed to achieve the secondary cooling effect, so as to improve the cooling capacity. Therefore, in the embodiment, a water level sensor is disposed in the evaporation box 20, the water level sensor is located in the evaporation box 20, the water level sensor is connected to the controller, and the controller is configured to control a water supply system to supply water to the evaporation box 20 according to a water level signal detected by the water level sensor.

That is, the amount of water in the evaporation cartridge 20 is detected by the water level sensor. When the water temperature sensor does not detect the water level signal, it indicates that the water level in the evaporation box 20 is reduced, and at this time, the controller controls the water supply system to supply water to the evaporation box 20, so as to ensure that the water in the evaporation box 20 meets the requirement of secondary cooling of the refrigerant in the coil assembly 32. When the water temperature sensor detects a water level signal, it indicates that the water level in the evaporation box 20 is high, and at this time, water may not be supplied to the evaporation box 20.

Alternatively, the water level sensor and the water level detecting member may be located at the same position or at different positions. The water level sensor and the water level detecting member may be the same component or may be two independent components. The controller may control the water supply system and the on-off valve based on a signal of the water level sensor or the water level detecting member, or may independently control the water supply system and the on-off valve.

It should be noted that the above is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures or equivalent flow transformations made by using the contents of the specification and the drawings, or applied directly or indirectly to other related technical fields, are included in the scope of the present invention.
