Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a coffee machine water tank assembly and a coffee machine. Background Technology

[0002] Most existing coffee machine water tanks are located at the rear of the machine and are removed or installed vertically, thus requiring a relatively high ceiling. Furthermore, installing the water tank vertically also increases the overall height of the coffee machine, further demanding more installation space.

[0003] In addition, most existing coffee machines only consider the valve core structure on the water tank side. In actual use, there is also water in the water supply line of the coffee machine. After the water tank is pulled out, the water tank will not leak through the valve core. However, some water will inevitably leak into the water tank installation cavity through the water supply line, which will cause inconvenience to the user. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a coffee machine water tank assembly. By changing the water tank to be installed horizontally, that is, to be installed or removed by operating in the horizontal direction, the height requirements of the usage site can be reduced, and the overall height of the coffee machine can also be reduced. In addition, by setting the seat water stop valve assembly and the water tank water stop valve assembly, water in the water outlet seat can be prevented from seeping into the installation cavity when the water tank is removed, thus ensuring the safety and hygiene of the product during use.

[0005] The second objective of this utility model is to provide a coffee machine having the aforementioned coffee machine water tank assembly and water tray. By placing the water tank on the rear side of the water tray, not only can horizontal installation be achieved, but the capacity of the water tank can also be increased.

[0048] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0049] Example 1

[0050] See Figures 1 to 9 This application first discloses a coffee machine water tank assembly, including a mounting frame 1 and a water tank 2. The mounting frame 1 has an internal mounting cavity 11 with an open front side. The mounting frame 1 has a water outlet seat 12 on its rear side, which communicates with the mounting cavity 11. The water outlet seat 12 has a seat stop valve assembly 13 inside. Specifically, the water outlet seat 12 has an internal water outlet chamber communicating with the mounting cavity 11. The seat stop valve assembly 13 is located in the water outlet chamber and can block or open the water outlet chamber. The water tank 2 can be moved back and forth in the horizontal direction to be installed into or pulled out of the mounting cavity 11 to achieve detachable installation in the mounting cavity 11. The water tank 2 has a water outlet 213 on its rear side, and the water outlet 213 has a water tank stop valve assembly 24 inside. Specifically, the spout 213 has an internal water outlet channel communicating with the interior of the water tank 2. The water tank stop valve assembly 24 is located within this water outlet channel, and the water tank stop valve assembly 24 can block or open the water outlet channel. The outer circumference of the spout 213 is smaller than the inner circumference of the spout base 12, so that when the water tank 2 is installed into the mounting cavity 11, the spout 213 can extend into the spout base 12. Preferably, the spout 213 is cylindrical.

[0051] Therefore, when the water tank 2 is installed into the mounting cavity 11, the water outlet 213 extends into the water outlet seat 12. The seat stop valve assembly 13 and the water tank stop valve assembly 24 abut against each other to open the water outlet 213 and the water outlet seat 12 respectively, thereby realizing the interconnection between the water outlet 213 and the water outlet seat 12. Water inside the water tank 2 can enter the water outlet seat 12 through the water outlet 213. When the water tank 2 is removed from the mounting cavity 11, the water outlet 213 separates from the water outlet seat 12. The seat stop valve assembly 13 resets and closes the water outlet seat 12 to prevent water in the water outlet seat 12 from seeping into the mounting cavity 11. The water tank stop valve assembly 24 resets and closes the water outlet 213 to prevent water in the water outlet 213 from seeping out.

[0052] Therefore, by changing the water tank 2 to a horizontal installation, that is, by operating in a horizontal front-to-back direction to install or remove the water tank 2, the height requirements of the usage site can be reduced, and the overall height of the coffee machine can also be reduced. In addition, by setting the seat water stop valve assembly 13 in the water outlet 12 and the water tank water stop valve assembly 24 in the water outlet 213, when the water tank 2 is removed, the seat water stop valve assembly 13 can reset and seal the water outlet chamber to prevent water in the water outlet chamber from seeping into the installation chamber 11, and the water tank water stop valve assembly 24 can reset and seal the water outlet channel, avoiding water leakage when the water tank 2 is removed, and ensuring the safety and hygiene of the product during use.

[0053] See Figure 7-8 The water outlet seat 12 has a partition 1211 inside, and a first through hole 1212 is formed on the partition 1211. Specifically, the water outlet seat 12 includes a front seat body 121 and a rear seat body 122 that are nested together. The interior of the front seat body 121 and the interior of the rear seat body 122 enclose the aforementioned water outlet cavity. Designing the water outlet seat 12 as a split structure of the front seat body 121 and the rear seat body 122 facilitates assembly and improves production efficiency. A seat sealing ring 123 is provided at the connection between the front seat body 121 and the rear seat body 122 to achieve a waterproof seal at the connection. The partition 1211 is integrally formed inside the front seat 121, and the partition 1211 divides the water outlet chamber into a front water outlet chamber and a rear water outlet chamber arranged in a front-to-back manner. The first through hole 1212 on the partition 1211 connects the front water outlet chamber and the rear water outlet chamber. Thus, by placing the partition 1211 inside the front seat 121, the first through hole 1212 can be formed in the front seat 121, which is closer to the water outlet 213 on the water tank 2 that it cooperates with. This facilitates the linkage between the seat water stop valve assembly 13 and the water tank water stop valve assembly 24 when the water tank 2 is assembled with the mounting frame 1, and can save the space occupied by the components, making the coffee machine more compact. The seat water stop valve assembly 13 is used to open or block the first through hole 1212 to open or close the water outlet chamber.

[0054] Of course, in other embodiments, the partition 1211 can also be set inside the rear seat 122. In this case, the water outlet 213 needs to be inserted to a deeper position to be linked with the seat water stop valve assembly 13, which can also achieve the same technical effect. There are no restrictions here.

[0055] More specifically, the seat-type water stop valve assembly 13 includes a first valve core 131 passing through the first through hole 1212, a first sealing ring 132 sleeved around the first valve core 131, and a first elastic element 133 abutting and cooperating with the first valve core 131; the first valve core 131 moves back and forth within the first through hole 1212, causing the first sealing ring 132 to close or open the first through hole 1212. Therefore, when the water outlet 213 of the water tank 2 is not inserted into the water outlet seat 12, under the elastic force of the first elastic element 133, the first sealing ring 132 on the first valve core 131 can abut against the first through hole 1212, sealing the gap between the first valve core 131 and the first through hole 1212. At this time, the front water outlet chamber and the rear water outlet chamber are not connected (e.g., Figure 8 As shown), the water outlet chamber is in a closed state; when the water tank 2 is installed into the mounting cavity 11 and the water outlet 213 extends into the front water outlet chamber of the front seat 121, it can drive the first valve core 131 to overcome the elastic force of the first elastic element 133 and move backward, so that the first sealing ring 132 separates from the first through hole 1212. At this time, the front water outlet chamber and the rear water outlet chamber are connected (as shown). Figure 9 As shown in the figure, the water outlet chamber is in the open state, and the water in the water tank 2 can enter the water outlet chamber through the water outlet 213.

[0056] In this embodiment, the first elastic element 133 is disposed between the rear seat body 122 and the first valve core 131. Specifically, the first elastic element 133 is a spring. The inner rear wall of the rear seat body 122 extends forward in the horizontal direction and is provided with a mounting post. The spring is respectively sleeved on the mounting post and the first valve core 131, and one end of the spring abuts against the inner rear wall of the rear seat body 122, and the other end of the spring abuts against the first valve core 131.

[0057] Of course, in other embodiments, the seat stop valve assembly 13 can also be set at the connection between the water outlet seat 12 and the mounting frame 1. The water outlet chamber can be opened or closed by opening or blocking the connection between the water outlet seat 12 and the mounting frame 1 through the seat stop valve assembly 13. The same technical effect can be achieved. Therefore, the setting position of the seat stop valve assembly 13 is not limited here.

[0058] Furthermore, a frame sealing ring 15 is provided at the connection between the front seat 121 and the mounting frame 1 to achieve a waterproof seal. The inner ring of the frame sealing ring 15 is provided with an elastic sealing edge 151. When the water outlet 213 is inserted into the front seat 121, the elastic sealing edge 151 abuts against the outer wall of the water outlet 213 to achieve a waterproof seal, thereby preventing the risk of water leakage when the water outlet 213 is inserted into the front seat 121.

[0059] In addition, a filter assembly 14 is provided in the front seat 121. The filter assembly 14 includes a filter 141 and a support shaft 142 passing through the filter 141. One end of the support shaft 142 is connected to the first valve core 131. Thus, the filter 141 can filter impurities and particles in the water, preventing them from entering the water outlet 12 and then entering the coffee machine water pump through the water outlet 12, thereby causing the impeller gap to be blocked and the water pump to fail.

[0060] When the water outlet 213 extends into the front seat 121, the water outlet 213 can abut against the filter screen 141 and drive the filter screen 141 to move backward. The support shaft 142 passing through the filter screen 141 can abut against and drive the first valve core 131 to overcome the elastic force of the first elastic member 133 and move backward, so that the first sealing ring 132 is disengaged from the first through hole 1212 to make the front water outlet chamber and the rear water outlet chamber connected. At the same time, the other end of the support shaft 142 can drive the water tank stop valve assembly 24 to open the water outlet channel.

[0061] See Figure 5-6 The water tank 2 also has a second through hole 214 connecting the water outlet 213 to the interior of the water tank 2. The water tank stop valve assembly 24 includes a second valve core 241 passing through the second through hole 214, a second sealing ring 242 sleeved around the second valve core 241, and a second elastic element 243 that abuts against the second valve core 241. The second valve core 241 can move back and forth within the second through hole 214 to close or open the second through hole 214. Thus, when the water outlet 213 of the water tank 2 is not inserted into the front seat 121, under the elastic force of the second elastic element 243, the second sealing ring 242 on the second valve core 241 can be driven to abut against the second through hole 214 and seal the gap between the second valve core 241 and the second through hole 214, so that the water outlet channel inside the water outlet 213 is not connected to the interior of the water tank 2 (e.g., Figure 6 As shown), the water outlet channel is in the closed state; when the water outlet 213 extends into the front seat 121, the other end of the support shaft 142 can abut against the second valve core 241 and drive the second valve core 241 to overcome the elastic force of the second elastic element 243 and move forward, so that the second sealing ring 242 is separated from the second through hole 214. At this time, the water outlet channel is in the open state, and the water outlet channel is connected to the inside of the water tank 2.

[0062] In this embodiment, the second elastic element 243 is a spring, and a step is provided on the second valve core 241. The spring is sleeved on the second valve core 241, with one end abutting against the step and the other end abutting against the inner wall of the water outlet 213.

[0063] See Figure 6 , Figure 8 as well as Figure 9 The coffee machine water tank assembly also includes a positioning structure disposed between the mounting frame 1 and the water tank 2. This positioning structure includes a positioning pin 16 passing through the bottom wall of the mounting cavity 11, a positioning elastic element 17 sleeved on and abutting against the positioning pin 16, and a positioning hole 215 formed at the bottom of the water tank 2. The positioning hole 215 is adapted to the shape of the end of the positioning pin 16. Preferably, the positioning elastic element 17 is a spring. Thus, when the water tank 2 is moved back and forth horizontally and inserted into the mounting cavity 11, the bottom of the water tank 2 first abuts against the positioning pin 16, causing the positioning pin 16 to overcome the elastic force of the positioning elastic element 17 and retract until the water tank 2 is fully inserted into the mounting cavity 11. At this point, the positioning pin 16 communicates with the positioning hole 215. Under the elastic force of the positioning elastic element 17, the end of the positioning pin 16 moves upward and engages with the positioning hole 215, thereby achieving the positioning and locking of the water tank 2. In addition, when it is necessary to pull the water tank 2 out of the mounting cavity 11, simply pull the water tank 2 forward until the positioning hole 215 disengages from the positioning pin 16. The operation is very convenient.

[0064] Therefore, by setting this positioning structure, the position of the water tank 2 is fixed after it is installed into the mounting cavity 11, thereby ensuring the stability and reliability of the mutual contact and cooperation between the seat water stop valve assembly 13 and the water tank water stop valve assembly 24, and thus ensuring smooth water discharge.

[0065] See Figure 5 The water tank 2 includes a water tank body 21, and a cover plate 22 is provided on the top of the water tank body 21. The cover plate 22 can seal the top of the water tank body 21 to prevent dust and impurities from falling into the water tank body 21. A transparent water level window 212 is also provided on the front side of the water tank body 21, so that users can easily observe the water level in the water tank 2 in real time, prevent the water level in the water tank 2 from being too low, and remind users to add water in time.

[0066] In addition, the water tank 2 also includes a front panel 23 located on the front side of the water tank body 21. The front panel 23 has an opening 231 through which the water level viewing window 212 passes. The bottom of the front panel 23 has a notch 232, and a handle groove communicating with the notch 232 is provided between the front panel 23 and the front side of the water tank body 21. Specifically, the bottom of the front side of the water tank body 21 has a first groove 211, and the bottom of the front panel 23 has an inwardly recessed second groove 233. The first groove 211 and the second groove 233 together form a handle groove for pulling out the water tank 2. Users can pull out the water tank 2 by reaching their hands into the handle groove, which is very convenient.

[0067] Example 2

[0068] See also Figure 1-9 This embodiment also provides a coffee machine, including a water tray 3 and the coffee machine water tank assembly of the above embodiment 1. The water tray 3 can move back and forth in the horizontal direction and is detachably mounted on the mounting frame 1. The water tank 2 is located behind the water tray 3, and the highest point of the water tank 2 is higher than the highest point of the water tray 3. Therefore, when the water tank 2 needs to be removed, the water tray 3 must first be removed from the mounting frame 1, and then the water tank 2 must be pulled out from the mounting cavity 11. Similarly, when the water tank 2 needs to be assembled, the water tank 2 must first be installed into the mounting cavity 11, and then the water tray 3 must be mounted on the mounting frame 1.

[0069] Therefore, by placing the water tank 2 behind the water receiving tray 3, not only can it be installed horizontally, but there is also no need to reserve space for installing the water receiving tray 3, so the capacity of the water tank 2 can be increased.

[0070] In summary, this utility model has the following technical effects:

[0071] (i) The water tank assembly of this utility model for a coffee machine reduces the height requirements of the work site and also lowers the overall height of the coffee machine by changing the water tank 2 to a horizontal installation, i.e., by operating in a horizontal direction to install or remove the water tank 2. In addition, by setting a seat water stop valve assembly 13 in the water outlet seat 12 and a water tank water stop valve assembly 24 in the water outlet 213, when the water tank 2 is removed, the seat water stop valve assembly 13 can reset and seal the water outlet seat 12 to prevent water in the water outlet seat 12 from seeping into the installation cavity 11; the water tank water stop valve assembly 24 can reset and seal the water outlet 213 to prevent water in the water outlet 213 from seeping out, thus avoiding water leakage when the water tank 2 is removed and ensuring the safety and hygiene of the product during use.

[0072] (ii) The coffee machine of this utility model can not only be installed horizontally by setting the water tank 2 on the rear side of the water receiving tray 3, but also increase the capacity of the water tank 2.

[0073] 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.
