A method and an apparatus for controlling a cooling in a water dispenser are disclosed. The method includes: S1, receiving a cooling instruction and entering a cooling mode according to the cooling instruction; S2, obtaining an operation parameter of the water dispenser; S3, determining whether a suspending condition is satisfied according to the operation parameter; S4, suspending a cooling if the suspending condition is satisfied; and S5, further determining whether a restarting condition is satisfied, performing the cooling and executing steps S2-S5 repeatedly until a cooling terminating condition is satisfied if the restarting condition is satisfied. Therefore, during the process of operating of the water dispenser, performances of the condenser and the evaporator may be restored to the optimal performance state by suspending the cooling, and when operating next, the evaporating temperature may drop very low, so that the performances of the condenser, the evaporator and the compressor may be developed multiple times, thus realizing the ultralow water temperature cooling and improving the cooling capacity.

A system for refilling the water reservoir of an appliance (such as found in a coffee maker, humidifier, etc.) takes the form of a fixture that receives a water line inlet tubing at its input (the tubing coupled to an existing water line). The fixture also includes outlet tubing, which is coupled to the reservoir of the appliance. Also included within the fixture is a shut-off valve that is used to control the flow from the inlet tubing to the outlet tubing. Thus, a user is able to control the flow of water to the reservoir in a manner where it is possible to quickly and easily refill the reservoir without removing the reservoir itself, or needing to transport water from a faucet to the appliance.

The present invention relates to a measurement device (10) for measuring a volume of liquid contained in a vessel, comprising: —a main vessel (12) for receiving a liquid; —a reference vessel (14) which has a smaller volume than the main vessel (12), wherein the main vessel (12) and the reference vessel (14) are fluidly connectable to each other as communicating vessels; —a pump (16) which is connected to the main vessel (12) and the reference vessel (14) for extracting liquid from the main vessel (12) and the reference vessel (14); —a minimum level sensor (26) which is configured to send a reference signal if a minimum liquid level within the reference vessel (14) is reached; —a first valve (20, 20′) via which the reference vessel (14) is fluidly connected to the pump (16), wherein the first valve (20, 20′) is configured to be closed off if the minimum liquid level within the reference vessel (14) is reached; and —a control unit (30) which is connected to the minimum level sensor (26, 26′) and the pump (16) and configured to measure a reference time between an activation of the pump (16) and a receipt of the reference signal, wherein the control unit (30) is further configured to calculate, based on the reference time and a flow rate of the pump (16), a liquid volume within the main vessel (12) and/or a total liquid volume within the main vessel (12) and the reference vessel (14) together.

Assemblies, machines, systems, and methods for the generation of superheated are discussed A steam super-heat assembly is employed for generating superheated steam for the preparation of coffee-based beverages. The assembly includes a body that includes an internal cavity, a heating element that includes heating surfaces positioned within the internal cavity, and a flow path within the internal cavity. The body also includes an input that enables fluid access into the internal cavity and an output that enables fluid egress out of the internal cavity. The heating element heats the heating surfaces of the heating element. The flow path enables fluid to flow from the input, through the internal cavity of the body, and to the output of the body. The heating surfaces form a portion of the flow path. When the fluid flows through the internal cavity, the fluid is in direct physical contact with the heating surfaces.

This invention discloses an airlift pumping mechanism for a fluid container, which is intended to address the problem of decreasing efficiency of the pumping mechanism when the liquid level in the container is low in the prior art. For this purpose, the airlift pumping mechanism comprises an air compressor and a riser tube assembly, wherein the riser tube assembly is located in a fluid container, and the air compressor is in communication with the riser tube assembly for feeding the compressed air to the riser tube assembly so that the same flows upward through the riser tube assembly together with the fluid in the fluid container. The pumping mechanism is characterized by further comprising a sunken cavity downwardly extending from the inner bottom surface of the fluid container, wherein the sunken cavity is located between the air compressor and the riser tube assembly and is in communication with the air compressor and the riser tube assembly. Due to the downward extension of the sunken cavity from the bottom surface of the container, the submergence ratio of the pumping mechanism can be significantly increased, thereby greatly increasing the pumping efficiency of the pumping mechanism at various liquid levels.
