Therefore, the above description should not be taken as limiting, but merely as exemplification of the embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the application.

[0062] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the application and, together with the general description of the application given above, and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0063] These and other characteristics of the present application will become apparent from the following description, given by way of non-limiting example with reference to the accompanying drawings.

[0064] It is also to be understood that even though a few examples of implementations of the present application are described in detail, many other equivalents and modifications can be made by those skilled in the art who are able to encompass the scope and spirit of the present application.

[0065] The above and other aspects, features, and advantages of the present application will become more apparent from the following detailed description, taken in conjunction with the accompanying drawings, when properly considered together.

[0066] Specific embodiments of the present application are described herein below with reference to the accompanying drawings; however, it is to be understood that the embodiments described are merely exemplary of the application and can be embodied in various forms. Well-known and / or redundant functions and structures are not described in detail to avoid obscuring the present application unnecessarily. Therefore, specific structural and functional details disclosed herein are not intended to limit the scope of the claims but merely as a representative basis for teaching one skilled in the art to employ the present application in virtually any appropriate detailed structure.

[0067] The specification can use phrases such as "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", which can refer to one or more of the same or different embodiments under the present application.

[0068] To solve the problems in the background art, the utility model discloses a kind of coffee machine, which can be used to make iced coffee. Ice water, cold water or ice cube can be used to extract coffee beverage.

[0069] As Figure 1 , Figure 2 , Figure 3 shown, the coffee machine comprises a body 1, the top of the body 1 is provided with a mounting position, and the coffee machine comprises a brewing box assembly 6 which can be mounted on the mounting position. Specifically, the brewing box assembly 6 can be placed on the body 1 as needed or taken off the body 1. As Figure 4 shown, the brewing box assembly 6 has a brewing bin 607, and ice water, cold water, ice blocks and the like can be placed in the brewing bin 607.

[0070] The brewing box assembly 6 has a first position and a second position, which can be determined by rotating the brewing box assembly 6 by 180° around the vertical direction. The body 1 has a first air duct 104 which is in communication with the outside, for example, the first air duct 104 can be in communication with the outside through the ventilation hole provided on the back plate of the body 1. When the brewing box assembly 6 is in the first position, the first air duct 104 can be in communication with the brewing bin 607 through the communication hole 606 on the brewing box assembly 6 and the brewing bin 607, at this time, the communication hole 606 faces the rear side of the coffee machine, that is, the communication hole 606 is close to and opposite to the first air duct 104. As Figure 3 shown, the first air duct 104 is provided with a first fan 105, which is used to send the outside heat into the brewing bin 607 through the first air duct 104 and the communication hole 606, so as to improve the melting speed of the ice blocks in the brewing bin 607. When the user needs to speed up the production of iced coffee, the first fan 105 is started, which sucks the outside air to the first section of the first air duct 104, and then enters the brewing bin 607 through the first air duct 104 and the communication hole 606 to accelerate the melting speed of the ice blocks in the brewing bin 607. At the same time, the air in the brewing bin 607 can be discharged out of the body 1 through the second section of the first air duct 104. The first section and the second section of the first air duct 104 can be separated by a partition plate of the body 1.

[0071] As Figure 4 and Figure 11 shown, the body 1 is provided with a cooling bin 103 and a second air duct 114, the cooling bin 103 is located below the brewing bin 607, and the cooling bin 103 can be placed with a cup body 4 for receiving ice water from the brewing bin 607. The cup body 4 can be placed with a filter assembly, and the filter assembly is placed with coffee powder to be brewed, and the coffee powder after being poured with ice water is dissolved and filtered through the filter assembly and then dripped into the cup body 4. The body 1 is provided with a door 3 at the position of the cooling bin 103, and the door 3 can be opened and closed. The door 3 can be opened to put in or take out the cup body 4, and when making iced coffee, the door 3 can be closed, so that the low-temperature air in the cooling bin 103 cannot flow out from the position of the door 3.

[0072] The second air duct 114 is also provided with a switch assembly 7. When the brewing box assembly 6 is in the second position, the switch assembly 7 is opened to enable the brewing bin 607 to communicate with the second air duct 114. That is, when the user needs to slow down the melting speed of the ice cubes in the brewing bin 607, the position of the brewing box assembly 6 can be adjusted to the second position, so that the connecting hole of the brewing box assembly 6 faces the front side of the machine body 1. Specifically, when the brewing box assembly 6 is in the first position, the switch assembly 7 is not in contact with the bottom surface of the brewing box assembly 6, or the switch assembly 7 is in contact with the bottom surface of the brewing box assembly 6 but is not subjected to the downward force of the brewing box assembly 6, and the switch assembly 7 is in a closed state. When the brewing box assembly 6 is in the second position, the bottom surface of the brewing box assembly 6 applies a downward force to the switch assembly 7 to open the switch assembly 7. As shown in Figure 5 For example, the brewing box assembly 6 can be removed from the machine body 1, then rotated by 180°, and then placed into the machine body 1.

[0073] As shown in Figure 11 The machine body 1 is also provided with a refrigeration mechanism and a second air fan 106. The second air fan 106 is located in the second air duct 114 and is used to send the cold energy released by the cooling side of the refrigeration mechanism into the cooling bin 103 and the brewing bin 607 to reduce the melting speed of the ice cubes in the brewing bin 607. That is, when the user needs to slow down the melting speed of the ice cubes in the brewing bin 607, the second air fan 106 can be started, and of course, the first air fan 105 has been closed at this time. The second air fan 106 can first blow the cold energy released by the cooling side of the refrigeration mechanism in the second air duct 114 to the cooling bin 103, and then enter the brewing bin 607 through the switch assembly 7 to reduce the temperature of the brewing bin 607, so as to slow down the melting speed of the ice cubes in the brewing bin 607. Of course, it can be understood that the second air fan 106 can also first blow the cold energy released by the cooling side of the refrigeration mechanism in the second air duct 114 to the brewing bin 607, and then enter the cooling bin 103 through the switch assembly 7 to reduce the temperature of the brewing bin 607. The direction of the cold energy released by the cooling side of the refrigeration mechanism depends on the direction of the blowing port of the second air fan 106.

[0074] By transferring the heat of the air outside the machine body 1 to the ice cubes in the brewing bin 607, the melting speed of the ice cubes in the brewing bin 607 is increased, the coffee making time is shortened, the user's waiting time is shortened, and the user experience is improved. At the same time, the energy consumption is reduced. The cold energy released by the cooling side of the refrigeration mechanism can also be sent into the cooling bin 103 and the brewing bin 607 to slow down the melting speed of the ice cubes in the brewing bin 607. At the same time, the ice coffee liquid in the cooling bin 103 can also be in a low-temperature environment, which meets the user's demand for different speeds of ice coffee making.

[0075] In some embodiments, as shown in Figure 6 andFigure 11 As shown, the brewing box assembly 6 includes a brewing box body 601, a one-way valve 603, and a brewing box lid 604.

[0076] The main body 1 is equipped with a brewing tank support 113. The brewing tank body 601 is a cylindrical container, but it can be configured with other structural forms according to actual needs. A handle 605 can also be provided at the top opening of the brewing tank body 601 for easy access to the brewing tank components 6. The brewing tank body 601 has a brewing chamber 607, the top of which has an opening. The brewing tank lid 604 can be hinged to the opening to seal it when closed. For example, when ice needs to be added to the brewing chamber 607, the brewing tank lid 604 can be opened, and after the ice is added, the lid 604 can be closed. This prevents dirt and dust from entering the brewing chamber 607 through the top opening, and also prevents the temperature inside the brewing chamber 607 from being affected by the external ambient temperature.

[0077] The brewing chamber body 601 is housed within the brewing chamber support 113. The brewing chamber support 113 can be a larger cylindrical structure than the brewing chamber body 601 to insulate the brewing chamber 607 of the brewing chamber body 601 from the outside environment. A gap may exist between the outer peripheral wall of the brewing chamber body 601 and the inner wall of the brewing chamber support 113. One-way valves 603 are installed at the first opening at the bottom of the brewing chamber body 601 and the second opening at the bottom of the brewing support. When the brewing chamber assembly 6 is placed on the machine body 1, the spring of the one-way valve 603 is pushed open, allowing water in the brewing chamber 607 to enter the cup body 4 in the cooling chamber 103 through the brewing head assembly 5 to brew iced coffee. When the brewing chamber assembly 6 is removed from the machine body 1, the spring returns to its original position, and the one-way valve 603 closes. The brewing head assembly 5 is located below the one-way valve 603.

[0078] According to the needs of making iced coffee, the brewing chamber assembly 6 can be placed on the machine body 1 so that the ice water in the brewing chamber 607 can enter the cooling chamber 103 to brew and make iced coffee.

[0079] In some embodiments, a first connecting hole 606 is provided on the side wall of the brewing box body 601, and a second connecting hole 606 is provided on the side wall of the brewing box support 113. The first connecting hole 606 and the second connecting hole 606 are directly opposite each other to form a connecting hole 606.

[0080] like Figure 3 As shown, when the brewing chamber assembly 6 is in the first position, the connecting hole 606 is located on the side near the first air duct 104 to connect the brewing chamber 607 and the first air duct 104.

[0081] like Figure 5As shown, in the case that the brewing box assembly 6 is in the second position, the communication hole 606 is located on the side away from the first air duct 104, and the cold air can enter the brewing chamber 607 through the communication hole 606 via the switch assembly 7.

[0082] According to the user's demand for increasing the melting speed of the ice cubes, the position of the brewing box assembly 6 can be adjusted to the first position, so that the first air duct 104 can be in communication with the brewing chamber 607, and the external air can enter the brewing chamber 607 through the first air duct 104 and the communication hole 606 to accelerate the melting speed of the ice cubes.

[0083] In some embodiments, as shown in Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , the switch assembly 7 includes a fixed seat 701, a movable seat 702, and a spring, which can be a supporting spring 703. The bottom of the movable seat 702 is connected to the top of the supporting spring 703, and the bottom of the supporting spring 703 is connected to the fixed seat 701, so that the movable seat 702 is movably arranged on the fixed seat 701. The fixed seat 701 can be provided with a wire groove, and the movable seat 702 can move up and down smoothly along the guide groove.

[0084] The fixed seat 701 can include a side plate and a bottom plate, and the bottom edge of the side plate is arranged on the bottom plate. The side plate is provided with a first through hole 7011. The movable seat 702 can also be arranged in a plate structure, and the movable seat 702 is arranged vertically. The movable seat 702 is provided with a second through hole 7021. In the case that the brewing box assembly 6 is in the second position, the brewing box assembly 6 applies a downward force to the movable seat 702, so that the movable seat 702 moves downward, the supporting spring 703 is compressed, the second through hole 7021 gradually approaches the first through hole 7011 located below the second through hole 7021, until they partially overlap, and then the first through hole 7011 and the second through hole 7021 completely overlap. The first through hole 7011 and the second through hole 7021 are opposite and overlap, so that the second air duct 114 is in communication with the brewing chamber 607. At this time, the brewing box assembly 6 is placed in the second position.

[0085] In the case that the brewing box assembly 6 is lifted or in the first position, the brewing box assembly 6 removes the force on the movable seat 702, and the supporting spring 703 is elongated and reset to push the movable seat 702 to move upward. The second through hole 7021 on the movable seat 702 moves upward and no longer overlaps or partially overlaps with the first through hole 7011, until the movable seat 702 completely blocks the first through hole 7011 on the side plate, so that the second air duct 114 is no longer in communication with the brewing chamber 607, and the cold air in the second air duct 114 cannot enter the brewing chamber 607.

[0086] A cold air duct sealing ring 704 can also be arranged at the first through hole 7011 to prevent cold air leakage.

[0087] The embodiment can adjust the position of the brewing box assembly 6 to the second position according to the user's demand for slowing down the melting speed of the ice cubes, and the switch assembly 7 can be opened to open the second air duct 114 and the brewing chamber 607, so that the cold energy on the cold release side of the refrigeration mechanism in the second air duct 114 can enter the brewing chamber 607, so that the temperature in the brewing chamber 607 is further reduced, and the melting speed of the ice cubes in the brewing chamber 607 is slowed down.

[0088] In some embodiments, as shown in Figure 11 and Figure 12 , the machine body 1 includes an inner shell 101 and an outer shell 102, and the inner shell 101 is provided with a mounting hole at a position corresponding to the cooling chamber 103, and the refrigeration mechanism is arranged at the mounting hole, and the cold release side of the refrigeration mechanism faces the cooling chamber 103. By arranging the refrigeration mechanism at the mounting hole of the cooling chamber 103 and making the cold release side thereof face the cooling chamber 103, the cold energy on the cold release side of the refrigeration mechanism can quickly enter the cooling chamber 103, thereby improving the refrigeration effect of the refrigeration mechanism on the cooling chamber 103.

[0089] The outer shell 102 is arranged outside the inner shell 101 and surrounds the rear back plate of the inner shell 101 to form a second air duct 114. The gas between the outer shell 102 and the inner shell 101 can circulate along the arrow direction in the figure, so that the cold energy released by the refrigeration mechanism from the cold release side during operation can circulate in the second air duct 114, and under the action of the second fan 106, the circulation speed of the gas in the second air duct 114 can be accelerated, thereby enabling the gas with cold energy to enter the cooling chamber 103 and the brewing chamber 607 at a faster speed, so as to slow down the melting speed of the ice cubes in the brewing chamber 607.

[0090] By arranging the refrigeration mechanism at the mounting hole of the cooling chamber 103 and making the cold release side thereof face the cooling chamber 103, the cold energy on the cold release side of the refrigeration mechanism can quickly enter the cooling chamber 103, thereby improving the refrigeration effect of the refrigeration mechanism on the cooling chamber 103.

[0091] In some embodiments, again in combination with Figure 11 and Figure 12 , the coffee machine further includes a power board assembly 109 arranged on the inner shell 101.

[0092] The refrigeration mechanism includes a refrigeration fin 110, a first heat-conducting plate 111, and a second heat-conducting plate 112.

[0093] The refrigeration sheet 110 can also be referred to as a thermoelectric semiconductor refrigeration assembly or a Peltier, etc., which refers to a patch divided into two sides, one side for cooling and the other side for heat dissipation, and functions as a heat conduction patch. The refrigeration sheet 110 is connected to the power board assembly 109, so as to start working after the refrigeration sheet 110 is connected to the current signal of the power board assembly 109, and to perform refrigeration processing on the gas in the second air duct 114.

[0094] The first heat conduction plate 111 is arranged on the cooling side of the refrigeration sheet 110, and is used to transmit the cold energy on the cooling side of the refrigeration sheet 110 to the cooling bin 103 and the brewing bin 607. The first heat conduction plate 111 can be made of a heat-conducting aluminum plate or other heat-conducting plates. The first heat conduction plate 111 can be arranged parallel to the refrigeration sheet 110, and the area of the first heat conduction plate 111 is greater than the area of the refrigeration sheet 110, so as to better transmit the cold energy released by the refrigeration sheet 110 on the cooling side to the cooling bin 103 and the brewing bin 607, improve the refrigeration effect on the cooling bin 103, and slow down the melting speed of the ice in the brewing bin 607.

[0095] The second heat conduction plate 112 is arranged on the heat dissipation side of the refrigeration sheet 110, and the second heat conduction plate 112 can also be made of a heat-conducting aluminum plate or other heat-conducting plates. The second heat conduction plate 112 can also be arranged parallel to the refrigeration sheet 110, and the area of the second heat conduction plate 112 is greater than the area of the refrigeration sheet 110, so as to better release the heat released by the refrigeration sheet 110 on the heat dissipation side to the outside of the machine body 1.

[0096] The first heat conduction plate 111 and the second heat conduction plate 112 are arranged on the cooling side and the heat dissipation side of the refrigeration sheet 110 respectively, so as to better transmit the cold energy on the cooling side of the refrigeration sheet 110 to the cooling bin 103 and the brewing bin 607, and improve the energy utilization efficiency of the refrigeration mechanism.

[0097] In some embodiments, the coffee machine further comprises a sensor 8 and a control panel 2.

[0098] The sensor 8 is arranged on the brewing bin assembly 6, and is used to detect the temperature of the brewing bin 607 and send a detection signal to the power board assembly 109, so as to control the working of the first fan 105 or the second fan 106 through the power board assembly 109 when the temperature in the brewing bin 607 is in different set temperature ranges. The sensor 8 can be but is not limited to an NTC sensor 8.

[0099] The control panel 2 is arranged on the inner shell 101 and connected with the power board assembly 109. Specifically, the control panel 2 can be arranged on the front side of the inner shell 101. The control panel 2 is provided with an operation button, which is used to send a starting signal to the power board assembly 109 to start the first fan 105 or the second fan 106.

[0100] For example, when the operation button is pressed or screwed or touched, the operation button is used to send a start signal to the power board assembly 109, and the power board assembly 109 starts the first fan 105 after receiving the first start signal, and the first fan 105 starts to work. Whether the first fan 105 is started or not is related to the user's use demand of the coffee machine, for example, the user needs to speed up the melting speed of the ice block, and then the first fan 105 can be started; if the user does not need to speed up the melting speed of the ice block, the first fan 105 can not be started. Similarly, when the user needs to slow down the melting speed of the ice block, the second fan 106 can be started, otherwise, the second fan 106 can not be started.

[0101] The temperature of the brewing chamber 607 is detected by the sensor 8, and the working of the first fan 105 and the second fan 106 is adjusted adaptively according to the detected temperature, so as to improve the utilization rate of external heat and cold generated by the machine body 1 as much as possible, thereby reducing energy consumption.

[0102] In some embodiments, the power board assembly 109 includes a first control switch and a second control switch.

[0103] The first control switch is connected with the control panel 2 and the first fan 105 respectively, and the first control switch is turned on after receiving the first start signal from the control panel 2 to start the first fan 105. The first control switch can be but not limited to a thyristor structure, i.e. a thyristor.

[0104] The second control switch is connected with the control panel 2 and the second fan 106 respectively, and the second control switch is turned on after receiving the second start signal from the control panel 2 to start the second fan 106.

[0105] The first control switch controls the start of the first fan 105, and the second switch controls the start of the second fan 106, so that the first fan 105 is started when the coffee machine needs to use external heat to melt the ice block, and the second fan 106 is started when it needs to use its own generated cold to melt the ice block, avoiding unnecessary start of the fan causing energy waste.

[0106] In some embodiments, the back plate 1022 of the shell 102 is provided with a plurality of heat dissipation holes 1021, and the plurality of heat dissipation holes 1021 are arranged at positions corresponding to the refrigeration mechanism on the back plate 1022 of the shell 102.

[0107] The coffee machine further comprises a heat dissipation fan 107, which can be arranged on the back plate of the inner shell 101. The power board assembly 109 comprises a third control switch connected with the control panel 2 and the heat dissipation fan 107 respectively. The third control switch is turned on after receiving a third starting signal from the control panel 2, so as to start the heat dissipation fan 107, and then the heat released by the second heat conduction plate 112 is discharged out of the machine body 1. The heat dissipation fan 107 can discharge the heat generated during the operation of the refrigeration mechanism out of the coffee machine, so as to avoid that the temperature of the machine body 1 of the coffee machine is too high to affect the refrigeration effect on the coffee in the cooling bin 103.

[0108] In some embodiments, as shown in Figure 11 The coffee machine further comprises a heat preservation structure 108, which is in the form of a barrel, and the heat preservation structure 108 is arranged on the outer side and bottom surface of the brewing bin assembly 6. The heat preservation structure 108 can heat insulate the brewing bin 607 and prevent the temperature of the brewing bin 607 from being affected by the ambient temperature, so as to be inconvenient to control. The heat preservation structure 108 can be made of heat preservation foam board, but is not limited thereto.

[0109] The above describes the embodiments of the present application in detail, but the present application is not limited to these specific embodiments. Based on the concept of the present application, those skilled in the art can make various modified embodiments, and these modifications shall fall within the scope of the present application.
