Description

Technical Field

[0001] The utility model relates to a household appliance, and more particularly to a coffee machine. Background Art

[0002] The coffee brewing process of a coffee machine is affected by the ambient temperature, resulting in inconsistent coffee extraction temperatures when brewing water of the same temperature with coffee powder at different ambient temperatures, making it difficult to ensure the same quality of the brewed coffee. Utility Model Content

[0003] The technical problem to be solved by the utility model is how to avoid the difference in coffee quality caused by the influence of ambient temperature.

[0004] The utility model provides a coffee machine, which includes:

[0005] A filtering component is provided with a brewing chamber;

[0006] A water injection device, disposed above the filter assembly, for delivering brewing water to the brewing chamber; and

[0007] The heating device is used to heat the filter component to a preset temperature before the water injection device delivers brewing water to the brewing chamber.

[0008] Thus, when brewing coffee using the coffee machine, firstly, coffee powder is sprinkled into the brewing chamber of the filter assembly, then the heating device is started to heat the filter assembly to a set temperature, and finally the water injection device is used to deliver brewing water into the brewing chamber to extract coffee. Since the filter assembly has been heated to a set temperature before the brewing water is injected, no matter what the ambient temperature is, it can be ensured that the temperature in the brewing chamber is kept substantially the same each time coffee is brewed, thereby ensuring that the quality of the coffee finally obtained is the same.

[0009] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model.

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0016] Embodiment 1

[0017] like Figure 1 As shown, Figure 1 The structure of the coffee machine in the first embodiment is shown. The coffee machine may be a drip coffee machine. The coffee machine includes a filter assembly 200, a water injection device 100, a heating device 400, a water supply assembly (not shown in the figure) and a housing 300.

[0018] The housing 300 is the framework structure of the coffee machine. The housing 300 may be a plastic housing or a metal housing. The housing 300 may be provided with a mounting hole 304.

[0019] like Figure 2 , 3 As shown, the water injection device 100 is arranged at the mounting hole 304 of the housing 300. The water injection device 100 includes a base 1 and a water injection member 2. The base 1 and the housing 300 are fixedly connected, and the base 1 and the housing 300 can be screwed, welded, bolted or bonded. A connecting portion 12 can be provided on the base 1, and the connecting portion 12 extends upward, and the connecting portion 12 is screwed to the housing 300. The base 1 is provided with a water inlet hole 111. The water inlet hole 111 can extend in the vertical direction and pass through the base 1. The water injection member 2 is connected to the base 1. An annular groove 21 is provided on the water injection member 2. The annular groove 21 can be a groove configured as a circular ring. The annular groove 21 is located below the water inlet hole 111 of the base 1. The opening of the annular groove 21 faces the water inlet hole 111 of the base 1. A water injection port 231 is also provided on the water injection member 2. The water injection port 231 is located at the bottom of the water injection member 2. The water injection port 231 may be disposed at the bottom of the annular groove 21 . The water injection port 231 may be disposed in a circular hole shape. The water injection port 231 penetrates the bottom of the annular groove 21 .

[0020] The water supply assembly is connected to the water inlet 111 of the water injection device 100 through a pipe. The water supply assembly is used to deliver brewing water to the water injection device 100. The water supply assembly includes a water tank, a water pump and an electric heater. The water tank is used to contain brewing water. The water inlet of the water pump is connected to the outlet of the water tank through a pipe, and the water outlet of the water pump is connected to the water inlet 111 of the base 1 through a pipe. The electric heater is arranged on the pipeline connecting the water outlet of the water pump and the water inlet 111 of the base 1. The electric heater is used to heat the brewing water output by the water pump to a set temperature, which can be 70°C to 100°C. The water inlet 111 is configured to deliver the brewing water input by the water supply assembly to the annular groove 21 of the water injection member 2.

[0021] like Figure 2 As shown, the filter assembly 200 is arranged below the water injection device 100. The filter assembly 200 includes a filter funnel 201. A brewing chamber 204 is arranged in the filter funnel 201. A feed inlet 202 is arranged at the top of the brewing chamber 204, and a liquid outlet 203 is arranged at the bottom of the brewing chamber 204. The feed inlet 202 is larger than the liquid outlet 203. The feed inlet 202 of the filter funnel 201 is arranged below the water injection port 231 of the water injection device 100. The feed inlet 202 of the filter funnel 201 faces the water injection port 231 of the water injection device 100. The water supply component injects brewing water into the water inlet hole 111 of the base 1, and the water inlet hole 111 of the base 1 transports the brewing water to the annular groove 21 of the water injection member 2. The brewing water in the annular groove 21 flows out of the annular groove 21 through the water injection port 231 at the bottom of the annular groove 21 and falls into the brewing chamber 204 below.

[0022] The heating device 400 can heat the filter assembly 200. The heating device 400 is used to convert electrical energy into thermal energy to heat the filter assembly 200. The heating device 400 is configured to heat the filter assembly 200 to a preset temperature. The preset temperature is a set value, which can be set by the user or uniformly set by the coffee machine before leaving the factory. The value range of the preset temperature can be, for example, 20°C to 60°C.

[0023] Thus, when using the coffee machine to brew coffee, firstly, coffee powder is sprinkled into the brewing chamber 204 of the filter assembly 200, then the heating device 400 is started to heat the filter assembly 200 to heat the filter assembly 200 to a set temperature, and finally the water injection device 100 is used to deliver brewing water into the brewing chamber 204 to extract coffee. Since the filter assembly 200 has been heated to a set temperature before the brewing water is injected, no matter what the ambient temperature is, it can be ensured that the temperature in the brewing chamber 204 is kept substantially the same each time coffee is brewed, thereby ensuring that the quality of the coffee finally obtained is the same.

[0024] In an exemplary embodiment, a gap is provided between the filter assembly 200 and the heating device 400. The filter assembly 200 and the heating device 400 have a certain distance in space.

[0025] The heating device 400 is configured to output heat radiation to the filter assembly 200 to heat the filter assembly 200. The heat radiation can be visible light and / or infrared. The heating device 400 includes an infrared heater or a heating wire. The infrared heater can emit infrared rays with a spectrum of 0.7um-80um. The emission and transmission of infrared rays are accompanied by obvious and directional energy transmission. The transmission of energy does not require an exchange medium and can be transmitted even in a vacuum. The advantages of the infrared heating method are: infrared rays have penetrating power and can heat both inside and outside at the same time; infrared rays do not require a heat transfer medium to transmit and have good thermal efficiency; infrared rays can heat locally and save energy; temperature control is easy, the temperature rises quickly, and it is relatively safe. After the heating wire is connected to the power supply, the temperature of the heating wire rises to a certain temperature and can emit heat radiation mixed with visible light and infrared rays.

[0026] The heating device 400 emits heat radiation to the filter assembly 200, and can heat the filter assembly 200 in the air. Since the filter assembly 200 often needs to be cleaned, the heating device 400 is separated from the filter assembly 200 to avoid the danger of leakage caused by the heating device 400 being wet.

[0027] In an illustrative embodiment, Figure 2 As shown, the heating device 400 is arranged on the water injection device 100. In this embodiment, the water injection device 100 further includes a cover 3. The cover 3 is connected to the base 1. The cover 3 and the base 1 can be snap-fitted. The heating device 400 is connected to the cover 3. The heating device 400 and the cover 3 can be snap-fitted, snap-fitted, bonded or screwed.

[0028] The heating device 400 is arranged on the water injection device 100, which can make the structure of the coffee machine more compact. At the same time, since the water injection device 100 is arranged above the filter assembly 200, the heating device 400 can transmit heat radiation from top to bottom to heat the brewing chamber 204 of the filter assembly 200, and the inner wall of the brewing chamber 204 is heated more evenly, which can further improve the consistency of coffee quality.

[0029] In an illustrative embodiment, the housing 300 includes a vertically extending column and a cantilever 302 extending horizontally from the column, and the water injection device 100 is disposed on the cantilever 302 .

[0030] In an illustrative embodiment, a powder falling channel 303 is further provided on the cantilever 302 of the housing 300. The powder falling channel 303 is used to transport coffee powder to the brewing chamber 204 of the filter assembly 200. The powder falling channel 303 vertically penetrates the bottom wall of the cantilever 302. The powder falling channel 303 is provided on one side of the water injection member 2 of the water injection device 100 and is provided close to the water injection member 2. The powder falling channel 303 is located above the filter assembly 200, and the coffee powder falls into the brewing chamber 204 through the powder falling channel 303.

[0031] The water injection member 2 is arranged in an annular shape. The annular groove 21 of the water injection member 2 is arranged coaxially with the water injection member 2. The axis of the water injection member 2 is arranged vertically. A vertically extending middle channel 221 is arranged in the middle of the water injection member 2. The cover member 3 covers the top of the middle channel 221. The heating device 400 is arranged in the middle channel 221 of the water injection member 2 and is connected to the cover member 3. A through hole can be arranged on the cover member 3, and the power cord of the heating device 400 can pass through the through hole of the cover member 3.

[0032] Thus, the heating device 400 is arranged in the middle channel 221 of the water injection part 2, and the structure of the coffee machine is more compact. At the same time, the heating device 400 is located in the middle of the water injection part 2, and the heat radiation output by the heating component can be absorbed by the filter component 200 as much as possible, thereby improving the heating efficiency.

[0033] In an illustrative embodiment, the inner wall of the filter funnel 201 of the filter assembly 200 is a conical surface, the brewing cavity 204 is a conical cavity, the diameter of the brewing cavity 204 gradually decreases from top to bottom, and the diameter of the feed port 202 at the top of the brewing cavity 204 is larger.

[0034] The brewing chamber 204 of the filter component 200 is coaxially arranged with the water injection component 2, and the heating component can directly irradiate the inner wall of the brewing chamber 204 to increase the temperature of the filter component 200. At the same time, the heating component can evenly heat the inner wall of the brewing chamber 204, and the temperature difference of each part of the heating component is small, which can further improve the consistency of coffee quality.

[0035] In an illustrative embodiment, the coffee machine further includes a bracket 500. The bracket 500 is disposed on the cantilever 302. The bracket 500 may be configured as an elongated strip. The bracket 500 extends from the cantilever 302. The filter assembly 200 is connected to the bracket 500, and the filter assembly 200 and the bracket 500 are detachably connected. In this embodiment, an inserting portion 501 is disposed at one end of the bracket 500 facing away from the cantilever 302, and the inserting portion 501 may be configured as a fork. The filter funnel 201 of the filter assembly 200 may be inserted into the inserting portion 501 of the bracket 500, thereby realizing the detachable installation of the filter assembly 200.

[0036] The filter assembly 200 is detachably connected to the bracket 500 , and the filter assembly 200 can be removed from the bracket 500 , so that the user can clean the filter assembly 200 .

[0037] In an exemplary embodiment, the bracket 500 extends downwardly from the cantilever 302 .

[0038] In this way, the filter assembly 200 can be suspended below the water injection device 100 and the heating device 400 through the bracket 500 .

[0039] In another exemplary embodiment, the bracket 500 extends horizontally from the cantilever 302 .

[0040] In an illustrative embodiment, the coffee machine further includes a temperature sensor and a controller. The temperature sensor is used to detect the ambient temperature. The temperature sensor may be disposed on the housing 300. The controller is electrically connected to the temperature sensor and the heating device 400. The controller may set the heating time and heating power of the heating device 400 according to the ambient temperature measured by the temperature sensor, so that the heating device 400 heats the filter assembly 200 to a preset temperature.

[0041] The heating time and heating power required for the heating device 400 to heat the filter assembly 200 to a preset temperature under each ambient temperature can be pre-calibrated, and the corresponding relationship between the ambient temperature and the heating time and heating power can be pre-stored in the controller. The controller can determine the heating time and heating power corresponding to the current ambient temperature according to the current ambient temperature measured by the temperature sensor, and then drive the heating device 400 with the heating power corresponding to the current ambient temperature, and control the heating time of the heating device 400 to be the heating time corresponding to the current ambient temperature, so that after the heating device 400 completes heating the filter assembly 200, the filter assembly 200 can reach the preset temperature.

[0042] In an illustrative embodiment, the water injection device 100 further includes a driving assembly 4. The water injection member 2 is rotatably connected to the base 1. The driving assembly 4 can drive the water injection member 2 to rotate around the axis of the annular groove 21, and the water injection port 231 rotates around the axis along with the water injection member 2, so that the brewing water in the annular groove 21 can be evenly scattered into the brewing chamber 204 along with the rotation of the water injection port 231, thereby ensuring the uniformity of coffee brewing.

[0043] In an illustrative embodiment, the base 1 includes a substrate 11. The substrate 11 is provided with an axial hole 112. The axial hole 112 is located in the middle of the substrate 11. The axial hole 112 vertically penetrates the substrate 11. The axial hole 112 may be a circular through hole.

[0044] The water injection member 2 includes an outer cylinder 24, an inner cylinder 22 and a bottom plate 23. The outer cylinder 24 and the inner cylinder 22 are both cylindrical. The inner diameter of the outer cylinder 24 is greater than the outer diameter of the inner cylinder 22. The length of the inner cylinder 22 is greater than the length of the outer cylinder 24. The inner cylinder 22 is arranged inside the outer cylinder 24. The inner cylinder 22 and the outer cylinder 24 are arranged coaxially. The inner cylinder 22 and the outer cylinder 24 are both arranged vertically. The bottom ends of the inner cylinder 22 and the outer cylinder 24 are flush. The bottom plate 23 is configured as a circular flat plate or an annular flat plate. The bottom plate 23 extends from the bottom end of the inner cylinder 22 to the bottom end of the outer cylinder 24, and the bottom plate 23 blocks the annular gap between the bottom ends of the inner cylinder 22 and the outer cylinder 24. The water injection ports 231 are all arranged on the bottom plate 23 and penetrate the bottom plate 23. The inner cylinder 22, the outer cylinder 24 and the bottom plate 23 enclose an annular groove 21, and the upward plate surface of the bottom plate 23 is the bottom surface of the annular groove 21. The inner cylinder 22 is inserted into the shaft hole 112 of the base plate 11, and there is a clearance fit between the inner cylinder 22 and the shaft hole 112. The base plate 11 is also located in the outer cylinder 24, and there is a clearance fit between the outer edge of the base plate 11 and the inner circumferential wall of the outer cylinder 24. The base plate 11 can cover the opening of the annular groove 21, and at the same time form a rotation connection with the water injection member 2.

[0045] The driving assembly 4 is arranged on the side of the base 1 facing away from the bottom plate 23 of the water injection member 2. The driving assembly 4 includes a transmission mechanism 42 and a motor 41. The transmission mechanism 42 is transmission-connected to the main shaft of the motor 41 and the inner cylinder 22 of the water injection member 2. The transmission mechanism 42 can transmit the torque output by the main shaft of the motor 41 to the inner cylinder 22, so that the inner cylinder 22 can rotate around its own axis.

[0046] In an illustrative embodiment, the transmission mechanism 42 includes a gear ring 421 and a gear 422.

[0051] In this embodiment, if Figure 4 As shown, the heating device 400a is constructed as an annular structure, which can be a circular ring. The inner diameter of the heating device 400a is greater than the outer diameter of the water injection member 2a. The heating device 400a surrounds the water injection member 2a.

[0052] A powder dropping channel 21a is provided in the middle of the water injection member 2a. The powder dropping channel 21a vertically penetrates the water injection member 2a. The powder dropping channel 21a is used to transport coffee powder to the brewing chamber 204 of the filter assembly 200, and the coffee powder falls into the brewing chamber 204 through the powder dropping channel 21a.

At the same time, the heating device 400a is constructed as an annular structure surrounding the water injection part 2a, and the volume of the heating device 400a can be set larger, and the filter component 200 can be heated with greater power, and the filter component 200 heats up quickly. In addition, when the annular heating device 400a heats the filter component 200, the filter component 200 can be evenly heated.
