Description

Technical Field

[0001] The utility model relates to the technical field of heating and temperature compensation systems, in particular to a heating and temperature compensation system for a semi-automatic Italian coffee machine. Background Technique

[0002] At present, there are three types of semi-automatic coffee machines on the market: mother-and-son boilers, double boilers, and multi-boilers. Most of the coffee machines we usually see are mother-and-son boiler systems. The working principle of the mother-and-son boiler is that the mother boiler heats water to about 120 °C and "scalds" the son boiler to about 90 °C through heat transfer. Therefore, it is called a heat exchange boiler. Since the heating element is on the mother boiler and the water temperature is dominated by the steam pressure of the mother boiler, it is not easy to control the extraction temperature. The double-boiler coffee machine has an independent steam boiler and an extraction boiler. The large boiler is responsible for steam and hot water for making tea, and the small boiler is responsible for the hot water extracted by the brewing head. The extraction water temperature is not easily affected, which greatly guarantees the extraction water temperature and steam pressure and ensures the quality of the coffee produced.

[0003] As disclosed in a heating mechanism of an automatic coffee machine with the authorization announcement number CN209003608U, it includes a water storage tank, a first water delivery pipe, a second water delivery pipe, a preheating water tank, and a heating boiler. The water storage tank is connected to the preheating water tank through the first water delivery pipe. The preheating water tank is connected to the heating boiler through the second water delivery pipe. A heating rod is arranged inside the preheating water tank. An outlet pipe is arranged at the bottom of the heating boiler. The outlet pipe is connected to a coffee brewing device. Water pumps are arranged on both the first water delivery pipe and the second water delivery pipe.

[0004] Although it realizes the heating mechanism of the automatic coffee machine, it can continuously and stably provide hot water at an appropriate temperature without being affected by the ambient temperature, thus ensuring the quality of the coffee brewed by the automatic coffee machine.

[0005] However, it does not solve the problem that the existing such heating and temperature compensation systems are generally not conducive to multi-level temperature detection and heating to output coffee liquid, it is not convenient to heat up the coffee liquid cooled in the delivery pipe in time, the output coffee liquid is prone to too low temperature and affects the taste, and it is not convenient to continuously and stably provide coffee liquid at a preset temperature. Content of the Utility Model

[0006] The purpose of the utility model is to provide a heating and temperature compensation system for a semi-automatic Italian coffee machine, so as to solve the problems put forward in the above background technique that the heating and temperature compensation system is not convenient for multi-level temperature detection and heating to output coffee liquid, it is not convenient to heat up the coffee liquid cooled in the delivery pipe in time, the output coffee liquid is prone to too low temperature and affects the taste, and it is not convenient to continuously and stably provide coffee liquid at a preset temperature.

[0007] To achieve the above object, the present utility model provides the following technical solution: A semi-automatic Italian coffee machine heating and temperature compensation system, including a heating furnace and a liquid inlet pipe. An inlet liquid pump is arranged outside the heating furnace. A brewing head is arranged on one side of the heating furnace away from the inlet liquid pump. A solenoid valve is arranged between the heating furnace and the brewing head. A coffee brewing port is installed at the center position of the bottom end of the brewing head. Electric heating sheets are symmetrically installed inside the brewing head and are fixedly connected to the brewing head. A plurality of heating tubes are installed at equal intervals inside the heating furnace. A first temperature detector is installed inside the heating furnace above the heating tubes and is fixedly connected to the heating furnace.

[0008] Preferably, one end of the inlet liquid pump is installed with a water pipe, and the water pipe extends into the heating furnace. The other end of the inlet liquid pump is installed with a liquid inlet pipe.

[0009] Preferably, one end of the solenoid valve is installed with a connecting pipe, and the connecting pipe extends into the heating furnace.

[0010] Preferably, the end of the solenoid valve away from the connecting pipe is installed with an outlet pipe, and the outlet pipe extends into the brewing head. A second temperature detector is installed inside the brewing head above the electric heating sheets.

[0011] Preferably, a controller is installed on the outer wall of the heating furnace, and the output end of the controller is electrically connected to the input ends of the heating tubes, the first temperature detector, the inlet liquid pump, the electric heating sheets, the solenoid valve, and the second temperature detector.

[0012] Compared with the prior art, the beneficial effect of the present utility model is that: This heating and temperature compensation system not only realizes multi-level temperature detection and heating type output of coffee liquid in the semi-automatic Italian coffee machine heating and temperature compensation system, facilitates the timely heating and temperature increase of the coffee liquid cooled in the conveying pipe, avoids the output coffee liquid having too low a temperature and affecting the taste, and facilitates the continuous and stable supply of coffee liquid at a preset temperature;

[0013] The temperature inside the heating furnace is detected by the first temperature detector. When the temperature is lower than the rated value, the first temperature detector feeds back to the controller, and the controller turns on the heating tube. The heating tube heats the liquid inside the heating furnace. The controller is operated to turn on the liquid inlet pump. Under the connection of the liquid inlet pipe, the external liquid enters the inside of the heating furnace through the water pipe. The high-temperature liquid inside the heating furnace is transported to the inside of the solenoid valve and the liquid outlet pipe through the connecting pipe, and is transported to the inside of the brewing head through the liquid outlet pipe. The temperature inside the brewing head is detected again by the second temperature detector. When the liquid inside the brewing head is lower than the rated temperature, the second temperature detector feeds back to the controller, and the controller turns on the heating element to heat the liquid inside the brewing head again. The temperature value detected by the second temperature detector is the same as the temperature value detected by the heating tube. Finally, the liquid is discharged through the coffee brewing port, realizing the multi-stage temperature detection heating type output of coffee liquid in the heating and temperature compensation system of the semi-automatic espresso machine, facilitating the timely heating and temperature rise of the coffee liquid cooled in the conveying pipe, avoiding the too low temperature of the output coffee liquid affecting the taste, and facilitating the continuous and stable supply of coffee liquid at the preset temperature; Brief Description of the Drawings
