Unless otherwise stated, "a plurality of" means two or more.

[0035] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0036] See Figures 1 to 6 This application discloses a compact coffee machine, including a frame body 1 and a water tank 2. The lower middle part of the frame body 1 is recessed rearward to form a water tank cavity 101. The water tank 2 can be installed or removed from the front side of the water tank cavity 101, thereby achieving horizontal installation of the water tank 2. Compared with the conventional method of installing and removing the water tank 2 vertically, horizontal installation of the water tank 2 can greatly reduce the overall height of the coffee machine.

[0037] Additionally, the system includes a first component, the top wall of which forms a mounting base 102 to support the first component; when the water tank 2 is installed into the water tank cavity 101, the water tank 2 is located below the first component. Preferably, the first component includes at least a water pump assembly 3 and a valve body assembly 4. Thus, by placing the first component on the mounting base 102 and above the water tank 2, that is, by utilizing the saved height space for installing the first component, the overall structure is more compact and the layout is more reasonable.

[0038] Of course, it should be noted that in other embodiments, the first component may also include other components besides the water pump component 3 and the valve body component 4, such as sensor components, pipeline components, etc., which are not limited here.

[0039] In addition, a water inlet seat 106 is installed on the rear side of the main frame 1, which is connected to the water tank cavity 101. A first water stop valve assembly is provided inside the water inlet seat 106. A water outlet 201 is provided on the rear side of the water tank 2, which is connected to the interior of the water tank 2. A second water stop valve assembly is provided inside the water outlet 201. Thus, when the water tank 2 is driven into the water tank cavity 101, the first water stop valve assembly and the second water stop valve assembly can cooperate to open the water inlet seat 106 and the water outlet 201 respectively, so that the water inside the water tank 2 enters the water inlet seat 106. When the water tank 2 is driven out of the water tank cavity 101, the first water stop valve assembly resets to close the water inlet seat 106, and the second water stop valve assembly resets to close the water outlet 201, thereby preventing water leakage between the water tank 2 and the water inlet seat 106 after the water tank 2 is removed.

[0040] Furthermore, the frame body 1 is provided with a support base 103 located at the upper front of the water tank cavity 101, and the support base 103 is connected to the mounting base 102. Additionally, a heating assembly 5 is included, which is mounted on the support base 103 and close to the valve body assembly 4. The water inlet of the water pump assembly 3 is connected to the water inlet seat 106 via a pipe, and the water outlet of the water pump assembly 3 is connected to the water inlet of the heating assembly 5 via the valve body assembly 4. Thus, when the water pump assembly 3 is started, water in the water tank 2 can be drawn out, pressurized, and pushed into the heating assembly 5 through the valve body assembly 4. The heating assembly 5 can heat the water to form hot water or steam. Preferably, the valve body assembly 4 includes a one-way valve, and the water pump assembly 3 is connected to the heating assembly 5 through the one-way valve to prevent hot water backflow; the water pump assembly 3 is a vibrating pump or a rotary pump, and the heating assembly 5 is a heating block or a accelerator; wherein, the specific structures of the valve body assembly 4, the water pump assembly 3 and the heating assembly 5 are all prior art, and are not the focus of this application, so they will not be described in detail here.

[0041] See Figure 2 as well as Figure 4-5The support base 103 has a brewing head 15 on one side of its bottom, which is close to the heating element 5. A steam rod 16 is also located on one side of the brewing head 15. The water outlet of the heating element 5 is connected to the brewing head 15 and the steam rod 16 via a valve assembly 4. Positioning the brewing head 15 close to the heating element 5 saves on connecting pipes and avoids heat loss during long pipe flow. This provides the brewing head 15 with hot water at the required temperature, improving the quality of the extracted coffee. It also provides the steam rod 16 with the required steam temperature, preventing heat loss during long pipe flow and condensation of some steam into water, thereby reducing the water content of the steam emitted by the steam rod 16 and improving the density and quality of the frothed milk. Preferably, the valve assembly includes at least two solenoid valves, and the water outlet of the heating element 5 is connected to the brewing head 15 and the steam rod 16 via two solenoid valves respectively. Therefore, when the portafilter filled with coffee powder is attached to the brew head 15 and the extraction function is activated, the hot water in the heating element 5 flows to the brew head 15 through a solenoid valve and pipes, and then to the coffee powder on the portafilter to extract coffee liquid. Additionally, when the steam wand 16 is inserted into a milk frother containing milk and the milk frothing function is activated, the steam in the heating element 5 flows to the steam wand 16 through another solenoid valve and pipes, thus frothing the milk to form milk foam. Specifically, the heating element 5 can be designed with one heating structure to provide both hot water and steam to the brew head 15 and the steam wand 16; alternatively, it can be designed with two heating structures, one providing hot water to the brew head 15 and the other providing steam to the steam wand 16, allowing for simultaneous coffee extraction and milk frothing.

[0042] Furthermore, the system also includes a coffee grinding assembly 9, which comprises a motor 901 and a grinding mechanism 902 connected to the motor 901. The grinding mechanism 902 is mounted on a support base 103, and the motor 901 is mounted on a mounting base 102 near the water pump assembly 3. A handle holder 17 is located on the other side of the bottom of the support base 103, and the powder outlet of the grinding mechanism 902 is connected to the handle holder 17. Additionally, a bean hopper assembly 10 is located above the grinding mechanism 902. The bean outlet of the bean hopper assembly 10 is connected to the bean inlet of the grinding mechanism 902, allowing coffee beans to be added to the grinding mechanism 902.

[0043] Therefore, when the grinding function is activated, the motor 901 starts and drives the grinding mechanism 902 to grind the coffee beans into coffee powder. The coffee powder can then fall out through the powder outlet and into the portafilter bowl installed on the portafilter holder 17, thus completing the powder collection.

[0044] Therefore, by setting a support base 103 connected to the mounting base 102 at the upper front of the frame body 1, the installation space is expanded, and the heating component 5 is set on one side of the top of the support base 103, the brewing head 15 and the steam rod 16 are set on one side of the bottom of the support base 103, the grinding mechanism is set on the other side of the top of the support base 103, and the handle bracket 17 is set on the other side of the bottom of the support base 103, so that the product structure is more compact and the space layout is more reasonable.

[0045] See Figure 3-5 The coffee machine also includes a circuit board assembly 6 and a control board assembly 7. The circuit board assembly 6 is located on one side of the frame body 1, near the valve body assembly 4, and is connected to the water pump assembly 3 and the valve body assembly 4. The control board assembly 7 is located on the front side of the support base 103 and is connected to the circuit board assembly 6. The control board assembly 7 includes a control board and several touch buttons on the control board. Thus, when the user presses a touch button to select a corresponding function, a control signal is sent to the circuit board assembly 6, which then controls the water pump assembly 3 and the valve body assembly 4 to achieve the corresponding function.

[0046] Therefore, by placing the circuit board assembly 6 on one side of the frame body 1, the side space of the frame body 1 is fully utilized, avoiding an increase in the overall height of the product and making the product more compact. Furthermore, by designing the circuit board assembly 6 close to the valve body assembly 4, it is avoided from being affected by the high temperature of the heating assembly 5, ensuring that the circuit board assembly 6 is in a suitable temperature environment and improving the service life of the electronic components on it. In addition, by placing the control board assembly 7 on the front side of the support base 103, it is convenient for users to observe and operate, resulting in a more reasonable layout.

[0047] See also Figure 1-2 The system also includes a water tray 8. The bottom of the frame body 1 is provided with a base plate 104, the rear side of which is connected to the front side of the bottom of the water tank cavity 101. The water tray 8 is detachably installed on the base plate 104. Therefore, when the water tank 2 needs to be removed, the water tray 8 must first be removed from the base plate 104, and then the water tank 2 must be pulled out from the water tank cavity 101. Similarly, when the water tank 2 needs to be assembled, the water tank 2 must first be installed into the water tank cavity 101, and then the water tray 8 must be installed on the base plate 104.

[0048] Therefore, by placing the water tank 2 behind the water receiving tray 8, not only can the water tank 2 be installed horizontally, but the capacity of the water tank 2 can also be increased.

[0049] See also Figure 2The coffee machine also includes a housing, which comprises at least a top cover 11 and a rear cover 13. The top cover 11 covers the top of the frame body 1, and the rear cover 13 covers the sides and rear of the frame body 1. Specifically, the top cover 11 is mounted on the mounting base 102 and the support base 103, thereby covering and protecting the water pump assembly 3, valve body assembly 4, heating assembly 5, and grinding assembly 9, while also making the product appearance more concise and elegant. The control panel assembly 7 is located on the front side of the top cover 11. The bean hopper assembly 10 is mounted on the top cover 11.

[0050] Specifically, a storage box cover 14 is rotatably connected to the back cover 13. A coffee machine accessory 18 is detachably installed on the back of the storage box cover 14. A space for accommodating the coffee machine accessory 18 is provided between the back cover 13 and the storage box cover 14. Specifically, a storage groove 1301 is formed on the back cover 13, and the storage box cover 14 is rotatably mounted on the storage groove 1301. The storage groove 1301 forms a space for accommodating the coffee machine accessory 18. The coffee machine accessory 18 includes a portafilter 1081, a cleaning brush 1082, and a cleaning needle 1083. Several limiting positions are provided on the end face of the storage box cover 14 facing the storage groove 1301. The portafilter 1081, the cleaning brush 1082, and the cleaning needle 1083 are respectively fixed on the several limiting positions to achieve limiting and fixing. Therefore, when the storage box cover 14 is rotated to close the storage slot 1301, the coffee machine accessories 18 are all placed inside the storage slot 1301; when the storage box cover 14 is rotated to open the storage slot 1301, the coffee machine accessories 18 open together with the storage box cover 14, making it convenient for users to take out and put in the coffee machine accessories 18 without removing other structures, making the operation very convenient.

[0051] Specifically, the storage box cover 14 is located on one side of the back cover 13, and the circuit board assembly 6 is located between the other side of the back cover 13 and the frame body 1. That is, the storage box cover 14 is located on the side opposite to the circuit board assembly 6 to facilitate the use of the overall space.

[0052] For example, it also includes a steam brush 19. The back of the frame body 1 is provided with a receiving groove 105 for accommodating part of the steam brush 19. The rear cover 13 is provided with a through hole 1302 that connects the receiving groove 105 and the storage groove 1301 respectively. The steam brush 19 passes through the through hole 1302 and extends into the storage groove 1301. In this way, by providing a receiving groove 105 on the frame body 1 and connecting the receiving groove 105 with the storage groove 1301, the storage space of the storage groove 1301 is expanded, thereby enabling the placement of more accessories and larger-sized accessories in a limited space. This makes it more practical and has a wider range of applications. Specifically, the receiving groove 105 is located at the rear of the frame body 1, specifically above the rear outer side of the water tank cavity 101. This allows the receiving groove 105 for accommodating the steam brush 19 to be formed by utilizing the gap between the water tank 2 and the water pump assembly 3 and valve body assembly 4 above it, resulting in a compact overall structural layout. Furthermore, once the storage box lid 14 is opened, the receiving slot 105 is exposed, making it easy for the user to take out the steam wand brush 19.

[0053] In addition, the housing also includes a bottom cover 12, which covers the bottom of the frame body 1 and forms a support; the rear cover 13 is located between the top cover 11 and the bottom cover 12, and the three together form the housing of the coffee machine.

[0054] In summary, this utility model has the following technical effects:

[0055] The coffee machine of this utility model has a compact structure. By changing the water tank 2 to be installed horizontally and placed in the water tank cavity 101 of the frame body 1, the overall height of the coffee machine can be reduced. In addition, by setting the water pump assembly 3 and the valve body assembly 4 on the mounting base 102 and above the water tank 2, that is, by using the saved height space to install the water pump assembly 3 and the valve body assembly 4, the overall structure of the machine is more compact and the layout is more reasonable.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
