Description

Technical Field

[0001] The invention relates to the technical field of coffee machines, in particular to a household integrated grinding coffee machine. Background Art

[0002] In recent years, integrated coffee machines with grinders have become increasingly popular among consumers. This type of coffee machine integrates the functions of grinding beans and brewing. When using it, users no longer need to equip themselves with grinders and brewing equipment separately. The operation process is simplified, which provides convenience for people to obtain coffee. Integrated coffee machines with grinders are mainly composed of the following parts: bean hopper, grinder, water tank, heater, pump system and control system. The bean hopper is used to store coffee beans to ensure the freshness of the coffee beans; the grinder grinds the coffee beans into powder according to the grinding coarseness set by the user; the water tank is used to store the water needed to make coffee; the heater heats the water to a suitable temperature; the pump system uses a pump to press water from the water tank into the coffee machine to form a stable pressure to ensure the quality of coffee extraction; and the control system is the core of the fully automatic coffee machine, responsible for controlling each link such as grinding, heating, and extraction.

[0003] However, the existing integrated grinding coffee machine also has some problems that need to be solved:

[0004] 1. The grinding mechanism is difficult to clean: The grinding mechanism of most integrated coffee machines is non-detachable and difficult to clean thoroughly. The ground powder easily adheres to the grinding blade and the inside of the mechanism, which will cause the coffee powder to harden and deteriorate over time, breed bacteria, and affect hygiene; moreover, the hardening of the coffee powder may damage the grinding mechanism;

[0005] 2. The coffee outlet lacks a stop device: The existing integrated grinding coffee machine generally does not have a stop device at its coffee outlet, which results in the inability to automatically control the uniform outflow of coffee liquid and the inability to accurately control the outflowing amount of coffee. Users can only rely on their own experience to judge when the coffee liquid stops flowing out and then take away the coffee cup. However, since the residual liquid of the coffee powder is easy to drip, it often causes stains on the bottom support table, affecting the appearance. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a household coffee machine with integrated grinding, so that the user can disassemble and remove the upper grinding structure at any time, conveniently cleaning the residual coffee powder between the upper grinding structure and the lower grinding structure, avoiding the hygiene problems caused by the residual powder and the impact on the grinding mechanism, and providing a flow stop device, so that the user can conveniently control the outflow of coffee and avoid residual coffee dripping onto the supporting table, thereby solving the problems raised by the above-mentioned background technology.

During installation, the upper transverse portion is passed through the inside of the anti-drip funnel 312 so that the middle vertical portion passes through the liquid outlet of the anti-drip funnel 312, and then the reset spring 322 is put on, and then the lower transverse portion is installed on the lower end of the middle vertical portion by means of threaded connection. When the pressing handles 3121 on both sides of the anti-drip funnel 312 are pressed by the pressing member 332, the anti-drip funnel 312 will move downward, so that the lower transverse portion of the stopper 321 is against the inner bottom surface of the liquid outlet funnel 311, and at the same time, the liquid outlet of the anti-drip funnel 312 is The opening is separated from the seal of the upper horizontal portion of the stop plug 321, so that coffee can flow out of the liquid outlet of the anti-drip funnel 312 into the liquid outlet funnel 311. The lower end of the stop plug 321 is also provided with a protrusion, so that when the anti-drip funnel 312 is pressed against the inner bottom surface of the liquid outlet funnel 311, there can still be a certain distance between the bottom surface of the stop plug 321 and the inner bottom surface of the liquid outlet funnel 311, which is convenient for coffee to flow out of the liquid outlet of the liquid outlet funnel 311. When the user pulls up the connecting rod handle, the pressing force of the contact pressing member 332 on the anti-drip funnel 312 causes the anti-drip funnel 312 to reset and move upward under the action of the reset spring 322, thereby making the upper horizontal portion of the stop plug 321 seal on the liquid outlet of the anti-drip funnel 312, thereby achieving a stop flow effect, and then the residual coffee placed on the coffee basket 313 can drip onto the supporting platform 10.

[0069] like Fig. 9 and Fig.10 As shown, the connecting rod starting structure 33 includes a connecting rod handle 331 and a pressing piece 332. The two ends of the connecting rod handle 331 can be rotatably installed on both sides of the installation box 5. Pressing mounting parts 333 are provided on both sides of the connecting rod handle 331. The pressing piece 332 is connected to the pressing mounting part 333 through a linkage rod 334. The pressing piece 332 is located above the pressing handle 3121 of the anti-drip funnel 312. The linkage rod 334 passes through the track slot holes 503 on both sides of the installation box 5 and can move in the track slot holes 503.

[0070] It should be noted that: a micro switch is also provided on the upper or lower side of the connecting rod handle 331, and the micro switch is electrically connected to the control system, so that when the connecting rod handle 331 is pulled downward, the micro switch can be pressed to start; in this embodiment, the micro switch is arranged under the pressing installation part 333 of the connecting rod handle 331 and is located on the outside of the installation box 5. When the user pulls the connecting rod handle 331 downward, the micro switch is pressed to start at the same time, and the control system 4 will control the heating system to heat the water in the water tank, and the control system 4 will also control The grinding mechanism 2 is started to grind the coffee beans; on the other hand, the two sides of the pulled-down connecting rod handle 331 are just located on the two sides of the supporting platform 10, which can well provide protective limits on both sides of the coffee cup to prevent the coffee cup from being accidentally bumped out of the supporting platform 10, thereby protecting the coffee cup; when the user pulls up the connecting rod handle 331, the micro switch is released, and the control system receives the signal that the micro switch is disconnected, and controls the disconnection of the heating system and the grinding mechanism 2, so that the heating system no longer heats the water in the water tank, and the grinding mechanism 2 stops grinding.

[0071] like Figure 1 , Figure 2 and Figure 3 As shown, the locking device 9 includes a locking limit frame 901 and a lock buckle 902, the lock buckle 902 is fixed on the coffee machine body 1, and the locking limit frame 901 is buckled on the grinding cover 6; the front side of the coffee machine body 1 is also provided with a detachable supporting platform 10, the supporting platform 10 is detachably mounted on the coffee machine and is located directly below the liquid discharge mechanism 3.

[0072] It should be noted that: in this embodiment, the front side of the coffee machine body 1 is provided with a support platform 10 mounting groove at the lower part, and the support platform 10 is provided with a matching support platform 10 mounting protrusion. During installation, the support platform 10 only needs to be mounted in the support platform mounting groove 102 on the front side of the coffee machine body 1, which is convenient for disassembly and assembly of the support platform 10 and convenient for cleaning. The support platform 10 is provided with at least one height mode to facilitate the use of coffee cups of different heights.
