Description

Technical Field

[0001] The utility model belongs to the technical field of coffee machines, and in particular relates to a heating tube assembly for a coffee machine. Background Art

[0002] The traditional coffee brewing process is cumbersome and often the brewed coffee tastes bad. Many people do not have time to brew coffee, so coffee machines came into being. When brewing coffee in a traditional coffee machine, the hot water generated by the heating device flows out through the hot water pipe inside the water tank. The hot water pipe runs through the inside of the water tank and will come into contact with the cold water inside the water tank. When the hot water flows through the hot water pipe, the cold water outside will absorb heat, thereby lowering the water temperature in the hot water pipe, affecting the temperature of the hot water required for brewing coffee, and seriously affecting the taste of the coffee. Existing coffee machines are often equipped with a heating pipe to specifically heat the cold water.

[0003] Chinese invention patent CN115005680A discloses a coffee machine heating tube, wherein a heater inner tube is arranged inside the heater, the heater inner tube is cylindrical, a water outlet is arranged on the inner wall of the heater inner tube and located at the top, a water inlet is arranged on the inner wall of the heater inner tube and located at the bottom, and a water tank is opened on the inner wall of the heater. The heater is placed inside the coffee machine, and the water pump inside the coffee machine works. The water pump works to introduce cold water into the heater inner tube through the water inlet, and the cold water passes through the heater inner tube and the water tank of the heater outer tube. The heater is powered on by the operation of the motor inside the coffee machine. After power-on, the outer wall of the heater converts electrical energy into heat energy through the resistance line, and the outer wall of the heater heats up sharply. At this time, the heat is conducted from the outer wall to the water tank, and the temperature of the water tank rises synchronously, thereby heating the cold water passing through the inside of the water tank. However, the heating tube of this coffee machine can only heat cold water, and cannot guarantee that all the hot water in the water outlet will be discharged when discharging water. If the coffee machine cannot be used continuously, a certain amount of water will remain in the water outlet. Since the air flow inside the water outlet is low, the accumulated water in the water outlet is difficult to evaporate, and it is easy to breed bacteria over time. Utility Model Content

[0025] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0026] In some embodiments of the present invention, Figure 1-Figure 2 As shown, a heating pipe assembly for a coffee machine is provided, including a bracket 100. A heating pipe assembly for a coffee machine also includes a heating pipe 200, a water pump 300, an air pump 400, a water outlet 500 and a pressure relief valve 600. The heating pipe 200 is fixedly arranged in the bracket 100. The water pump 300 is fixedly installed on one side of the bracket 100, and the water pump 300 is communicated with the heating pipe 200. The air pump 400 is fixedly installed on one side of the bracket 100. The air pump 400 is communicated with the heating pipe 200. The pressure relief valve 600 is communicated with the heating pipe 200.

[0027] The water pump 300 is connected to an external water supply device to introduce cold water into the heating pipe 200. The cold water is heated by the heating pipe 200 to become hot water, and flows from bottom to top toward the water outlet 500 under the action of the water pump 300. After the heating is completed, the hot water is discharged from the water outlet 500 under the action of the air pump 400. The utility model sets an air pump 400 and connects the air pump 400 to the heating pipe 200. Gas is pressed into the heating pipe 200 through the air pump 400. The high-pressure gas will push the hot water out of the water outlet 500, thereby avoiding residual hot water in the pipe of the water outlet 500.

[0028] In other embodiments of the utility model, two one-way valves are provided in the heating tube 200, which are used to limit the backflow of hot water and the high-pressure gas pumped by the air pump 300. When heating cold water, the hot water can only flow in one direction from bottom to top due to the pumping effect of the water pump 300 and the one-way valve. After the heating is completed, the air pump 300 pumps in high-pressure gas. Under the action of the two one-way valves, the high-pressure gas will not flow into the heating tube 300, but will all flow out through the pipeline of the water outlet 500.

[0029] like Figure 1 As shown, the utility model utilizes a bracket 100 to integrate a heating tube 200, a water pump 300 and an air pump 400. The overall integration is relatively high, which is beneficial to reducing the overall volume of the heating tube 200, so that the heating tube 200 can be more conveniently installed in the coffee machine.

[0030] It should be noted that the external water supply device can be a tap water pipe or a water reservoir. As for how the water pump 300 is connected to the external water supply device, it is a conventional technical means in the art, so it will not be elaborated in detail here.

[0031] like Figure 1 As shown, in other embodiments of the present invention, the bracket 100 includes an upper mounting seat 110, a lower mounting seat 120 and a bracket body 130. The lower end of the heating tube 200 is fixedly mounted on the lower mounting seat 120. The upper end of the heating tube 200 is fixedly mounted on the upper mounting seat 110. A mounting groove 131 is provided on one side of the bracket body 130. The tube body of the heating tube 200 is installed in the mounting groove 131. The air pump 400 is fixedly mounted on the upper end of the bracket body 130. The water pump 300 is fixedly mounted on the lower end of the bracket body 130.

[0032] Specifically, the upper mounting seat 110 and the lower mounting seat 120 not only cooperate with each other to clamp and fix the heating pipe 200, but also play a connecting role. Through the upper mounting seat 110 and the lower mounting seat 120, the entire heating pipe 200 assembly can be installed in most places.

[0033] like Figure 1As shown, in some other embodiments of the utility model, a vent pipe 111 is provided at the upper end of the upper mounting seat 110. The vent pipe 111 is connected to the heating pipe 200, and the vent pipe 111 is connected to the air pump 400. The water outlet 500 is provided on one side of the vent pipe 111. When discharging hot water, the air pump 400 presses the high-pressure gas into the heating pipe 200 through the vent pipe 111, thereby pressing the hot water in the heating pipe 200 into the water outlet 500. It should be noted that there can be many ways to arrange the vent pipe 111 in the heating pipe 200. As for how to arrange the vent pipe 111 to fully press out the hot water, those skilled in the art can obtain it through a limited number of experiments, and it is related to the specifications of the vent pipe 111, so the arrangement of the vent pipe 111 will not be described in detail here.

[0034] like Figure 1 As shown, in other embodiments of the present invention, a connecting seat 112 is installed at the upper end of the upper mounting seat 110. The connecting seat 112 is fixedly connected to the upper mounting seat 110 by screws. The connecting seat 112 is communicated with the vent pipe 111. The air pump 400 is connected to the connecting seat 112 and thus communicated with the vent pipe 111.

[0035] like Figure 1 As shown, in some other embodiments of the present invention, the connection base 112 is provided with three screw holes, and the angle between each screw hole is 120°. The connection base 112 is connected to the connection base 112 by screw threads, and the connecting line between the three connection holes forms an equilateral triangle, which ensures the stability of the connection base 112.

[0036] like Figure 1 As shown, in some other embodiments of the present invention, the air pump 400 is connected to the connecting seat 112 through a hose.

[0037] like Figure 1 As shown, in some other embodiments of the utility model, the pressure relief valve 600 is connected to the heating pipe 200 through a plastic tube, and the plastic tube extends into the lower mounting seat 120 and is connected to the heating pipe 200. Specifically, when the pressure inside the heating pipe 200 is too high, the pressure relief valve 600 automatically opens, and the heating pipe 200 can be depressurized in time. Specifically, a pressure gauge or a pressure sensor can be provided in the heating pipe 200. When it is sensed that the pressure of the heating pipe 200 is too high, the pressure relief valve is opened manually or automatically by an automatic control system such as a PLC, thereby adjusting the pressure inside the heating pipe 200.

[0038] like Figure 1As shown, in other embodiments of the present invention, the upper mounting seat 110 and the lower mounting seat 120 are both fixedly connected to the bracket body 130 by screws.

[0039] like Figure 1 As shown, in some other embodiments of the present invention, the lower mounting seat 120 extends outward to form a mounting platform 121. The water pump 300 is fixedly mounted on the mounting platform 121.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
