Description

Technical Field

[0001] This application belongs to the field of coffee machine technology, and in particular relates to a hot and cold coffee machine. Background Technology

[0002] To facilitate coffee dispensing, coffee machines integrate a cup-holding area, utilizing the heat radiation from the heating element to create a cup-warming zone. Some multi-functional coffee machines that integrate iced coffee also include a refrigerator for chilling cups or iced coffee. For example, a multi-functional coffee machine disclosed in Chinese patent application CN101243946A has a separate refrigerator for chilling cups or iced coffee. However, this refrigerator lacks a cup-warming zone, is excessively large, takes up space, is inconvenient to remove cups from, is difficult to clean, and is prone to bacterial growth, resulting in a poor user experience. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide an integrated hot and cold coffee machine with a cold and warm cup area.

[0004] The technical solution adopted in this application embodiment is an integrated hot and cold coffee machine, including a body and an ice-making unit and a heating element disposed within the body. The integrated hot and cold coffee machine further includes: A cold cup area is provided on the machine body. The cold energy generated by the refrigeration system of the ice-making unit is conducted to the cold cup area to cool the cups placed in the cold cup area. A cup warming area, located on the body, is used to place cups. The heat generated by the heating pot is conducted to the cup warming area to heat the cups placed there.

[0005] In an optional embodiment, the machine body is further provided with a flow guide channel, which is located near the cold cup area. The flow guide channel is connected to a water tank via a water pump, which pumps water from the water tank into the flow guide channel. The water in the flow guide channel cools the cold cup area and then flows out, falling back into the water tank along the evaporator of the refrigeration system. This cleverly utilizes the cold water from the ice-making unit to provide cooling to the cold cup area, achieving the effect of cold cups without the need for additional components, thus achieving high efficiency, energy saving, and a simplified structure.

[0006] In an optional embodiment, the body includes a top cover, which is partially recessed to form a cold cup area with a bottom wall; the bottom wall of the cold cup area covers the upper opening of the guide channel, or the guide channel is covered by a cover plate, and the bottom wall of the cold cup area abuts against the upper surface of the cover plate. The structure is simple, highly stable, and provides good cooling performance.

[0007] In an optional embodiment, the flow guide trough is formed by a trough wall and a trough bottom, creating an open-top structure. The trough wall includes a first trough wall and a second trough wall facing each other. A water inlet is provided on the portion of the trough bottom near the first trough wall, and the outlet of the water pump is connected to the water inlet. A flow guide plate is provided inside the flow guide trough near the second trough wall. The top side of the flow guide plate is close to the bottom wall or cover of the cold cup area, and the bottom side of the flow guide plate is connected to the trough bottom. A flow guide opening is provided on the trough bottom between the flow guide plate and the second trough wall, so that when the flow guide trough is full, water overflows through the top side of the flow guide plate and is discharged through the flow guide opening. The flow guide trough structure is cleverly and reasonably designed, allowing the cold water inside to be as close as possible to the cover, effectively transferring cold energy to the cold cup area.

[0008] In an optional embodiment, the refrigeration system includes an evaporator, a compressor, a condenser, and a capillary tube connected in series to form a closed loop via refrigerant pipes; the refrigerant pipe between the capillary tube and the evaporator is coiled around the outer surface of the cold cup area to conduct cold energy to the cold cup area. The design is ingenious and reasonable, ensuring effective cold cup cooling.

[0009] In an optional embodiment, the refrigeration system includes a main evaporator, a compressor, a condenser, and a capillary tube connected in series to form a closed loop via refrigerant pipes. An auxiliary evaporator is connected in series on the refrigerant pipe between the capillary tube and the main evaporator. The auxiliary evaporator is located in a channel communicating with the cold cup area, and a fan is also provided in the channel to deliver the cooling capacity generated by the auxiliary evaporator into the cold cup area. By adding an auxiliary evaporator and utilizing air cooling, the cold cup area can be effectively cooled.

[0010] In an optional embodiment, one end of the channel is connected to the cold cup area, and the other end of the channel is an open opening communicating with the outside. The fan is a blower or a suction fan. When the fan is a blower, it is located at the open opening and is used to blow air onto the auxiliary evaporator to transfer cold energy to the cold cup area. When the fan is a suction fan, it is located in the channel between the auxiliary evaporator and the cold cup area and is used to draw the cold energy generated by the auxiliary evaporator into the cold cup area. This design is reasonable and facilitates the delivery of cold energy from the auxiliary evaporator to the cold cup area.

[0011] In an optional embodiment, the cold cup area is provided with a sealing cover. When the sealing cover is closed, it creates a sealed space in the cold cup area. When the sealing cover is open, cups can be placed or removed. This prevents cold air loss and improves the cold cup effect.

[0012] In an optional embodiment, the hot and cold coffee machine further includes a controller; a temperature sensor is provided in the cold cup area, and both the temperature sensor and the fan are connected to the controller. The temperature sensor is used to detect the temperature of the cold cup area and send the detected temperature signal to the controller. The controller receives the temperature signal and controls the fan to start and stop according to the temperature signal. In this way, the temperature of the cold cup area can be precisely controlled to achieve the best cold cup effect; and / or The cold cup area is also equipped with a UV lamp. When the sealing lid is closed, the UV lamp is activated; when the sealing lid is opened, the activation is deactivated, and the UV lamp stops working. The UV lamp sterilizes and disinfects the cups in the cold cup area, improving hygiene and safety.

[0013] In an optional embodiment, the body includes a top cover, which is partially recessed to form the cup warming area. The heating pot is located below the cup warming area, and a surrounding barrier is provided around the heating pot to collect the heat generated by the heating pot and radiate the heat upwards to the cup warming area.

[0014] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: In order to match the functions of iced coffee and hot coffee, this application cleverly combines the heating pot and the evaporator of the cooling system, and integrates the cold cup area and the warm cup area on the body to fully maintain the taste of coffee at different temperatures when receiving coffee, thereby enhancing the user's drinking experience.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0034] This application provides an integrated hot and cold coffee machine, including a body 1 and an ice-making unit and a heating pot 8 disposed within the body 1. The ice-making unit is used to make ice cubes, and the heating pot 8 is used to heat the water for coffee extraction, so that the coffee machine of this application can make both hot and iced coffee.

[0035] like Figure 1 As shown, the integrated hot and cold coffee machine of this application embodiment further includes a cold cup area 11 and a warm cup area 12. The cold cup area 11 is disposed on the machine body 1, and the cold energy generated by the refrigeration system of the ice-making unit is conducted to the cold cup area 11 to cool the cup 10 placed in the cold cup area 11. The warm cup area 12 is disposed on the machine body 1 and is used to place the cup 10. The heat generated by the heating pot 8 is conducted to the warm cup area 12 to heat the cup 10 placed in the warm cup area 12.

[0036] The coffee machine in this embodiment integrates a warming cup area 12 and a cold cup area 11 for placing cups 10 respectively. The warming cup area 12 and the cold cup area 11 provide heat and cold to the cups 10 in the warming cup area 12 and the cold cup area 11 respectively through the heating pot 8 and the cooling system, so that cups 10 of different temperatures are configured to hold hot coffee and iced coffee respectively. When brewing hot coffee, the cups 10 in the warming cup area 12 are used to collect the coffee liquid, and when brewing iced coffee, the cups 10 in the cold cup area 11 are used to collect the coffee liquid, so as to maintain the taste of coffee at different temperatures and enhance the user's drinking experience.

[0037] The cooling capacity generated by the refrigeration system can be transferred to the cold cup area 11 in various ways, and this application does not specifically limit this. The following describes the methods of transferring cooling capacity to the cold cup area 11 using different embodiments.

[0038] Example 1 like Figures 2 to 5 As shown, the machine body 1 also has a guide channel 2, which is located near the cold cup area 11. The evaporator 32 of the refrigeration system is located below the guide channel 2, and the water tank 37 of the ice-making unit is located below the evaporator 32. The guide channel 2 is connected to the water tank 37 via a water pump 38. The water pump 38 is used to send water from the water tank 37 into the guide channel 2. The water in the guide channel 2 cools the cold cup area 11 and flows out, falling back into the water tank 37 along the evaporator 32. In this embodiment, the cold water from the ice-making unit of the coffee machine is used to transfer the cooling energy to the cold cup area 11, ensuring the low temperature of the cups 10 in the cold cup area 11. The cold water from the ice-making unit is cleverly used to cool the cold cup area 11, directly improving the coffee taste and consumer experience in a highly efficient and energy-saving way, achieving a dual optimization of quality and cost.

[0039] Continue to combine Figure 2 The main body 1 includes a top cover 13, which is partially recessed to form a cold cup area 11 with a bottom wall 111. A flow channel 2 is placed below the cold cup area 11, and its upper end is covered by a cover plate 28. The bottom wall 111 of the cold cup area 11 is attached to the upper surface of the cover plate 28. The cold cup area 11 is integrally formed on the top cover 13, providing structural stability. Furthermore, the bottom wall 111 of the cold cup area 11, through contact with the cover plate 28, allows the cold energy of the cold water in the flow channel 2 to be conducted to the cold cup area 11, ensuring the cooling effect of the cold cup area 11.

[0040] Furthermore, to ensure the sealing effect of the cover plate 28 on the guide channel 2 and prevent cold water in the guide channel 2 from leaking out from the upper opening of the guide channel 2, an annular groove 25 is provided on the outer periphery of the upper opening of the guide channel 2. A sealing ring 26 is embedded in the annular groove 25, and the sealing ring 26 protrudes upward from the annular groove 25. The cover plate 28 covers the upper opening of the guide channel 2, and the lower end face of the cover plate 28 presses against the sealing ring 26.

[0041] To simplify the structure, the cover plate 28 can be removed, and the upper opening of the guide channel 2 can be directly covered by the bottom wall 111 of the cold cup area 11.

[0042] The flow guide trough 2 can be an open-top structure formed by the trough walls and the trough bottom 23. For example, the flow guide trough 2 is a rectangular trough with an open top. Figure 5 As shown, the tank wall includes a first tank wall 21 and a second tank wall 22 facing each other. A water inlet hole 231 is provided on the portion of the tank bottom 23 near the first tank wall 21, and the outlet of the water pump 38 is connected to the water inlet hole 231. For example, as... Figures 2 to 5 As shown, a pipe connector 24 is provided on the water inlet 231. One end of the water inlet pipe 381 is connected to the pipe connector 24, and the other end of the water inlet pipe 381 is connected to the outlet of the water pump 38. The inlet of the water pump 38 is connected to the bottom of the water tank 37. Thus, when the water pump 38 starts, it can send water in the water tank 37 into the guide channel 2 through the water inlet 231. The guide channel 2 is provided with a guide plate 27 near the second tank wall 22. The top side of the guide plate 27 is close to the bottom wall 111 or cover plate 28 of the cold cup area 11, and the bottom side of the guide plate 27 is connected to the bottom 23 of the tank. The guide plate 27 actually divides the guide channel 2 into a first area near the first tank wall 21 and a second area near the second tank wall 22. A flow guide port 232 is provided on the bottom 23 of the tank (i.e., the bottom 23 of the second region) between the guide plate 27 and the second tank wall 22, so that when the water in the guide channel 2 is full, it overflows through the top side of the guide plate 27 and is discharged through the flow guide port 232. The guide channel 2 has a simple and reasonable structure, which allows the cold water in it to be as close as possible to the cover plate 28, thereby effectively transferring the cold energy to the cold cup area 11.

[0043] In order to ensure that the water flowing out of the guide port 232 of the guide channel 2 covers the outer surface of the evaporator 32 below as much as possible, the guide port 232 can be set as a long strip, and the extension direction of the long strip is consistent with the extension direction of the guide plate 27.

[0044] like Figure 3 As shown, when making iced coffee, first, water is added to the water tank 37. Then, the ice-making unit and water pump 38 of the coffee machine are started. The water pump 38 draws water from the water tank 37 into the guide channel 2. When the water in the guide channel 2 rises to the position of contacting the cover plate 28, it flows along the upper edge of the guide plate 27 into the space between the guide plate 27 and the second tank wall 22, then falls through the guide outlet 232 onto the evaporator 32, and falls back into the water tank 37 along the evaporator 32. In this cycle, the water is cooled, making the water in the water tank 37 cold water, while ice cubes form on the evaporator 32. In this way, while the coffee machine is making ice, the cold water for making ice flows through the guide channel 2, allowing the cold water to be transferred to the cold cup area 11. Cups 10 placed in the cold cup area 11 can achieve a cold cup effect. Figure 3 The direction of the middle arrow indicates the direction of water flow.

[0045] Example 2 like Figure 6 As shown, the refrigeration system includes an evaporator 32, a compressor 33, a condenser 34, and a capillary tube 35, which are connected in series to form a closed loop via refrigerant pipes 31. The refrigerant is compressed into a high-pressure gas by the compressor 33, enters the condenser 34 through the refrigerant pipes 31, condenses into a liquid state in the condenser 34, and then flows into the evaporator 32 after being throttled at the capillary tube 35. In the evaporator 32, it absorbs heat from the external water, becomes a high-temperature gas, and enters the compressor 33. This cycle achieves the refrigeration effect. The refrigerant pipe 31 between the capillary tube 35 and the evaporator 32 is coiled around the outer surface of the cold cup area 11, allowing the cold energy of the refrigerant in the refrigerant pipe 31 to be conducted to the cold cup area 11. In this way, the refrigeration system can simultaneously begin making ice and transfer cold energy to the cold cup area 11, cooling the cup 10 placed in the cold cup area 11 and achieving the effect of a cold cup.

[0046] like Figure 7 and Figure 8 As shown, the cold cup area 11 can be formed by a partial downward recess in the top cover 13 of the coffee machine body 1. The refrigerant pipe 31 is coiled around the outer bottom surface of the recessed portion. This facilitates effective transfer of cold air to the cold cup area. For example, as... Figure 8 As shown, the refrigerant pipe 31 is wound in an S-shaped bend to maximize the amount of refrigerant pipe 31 laid within a limited area and improve the heat transfer efficiency. Figure 8 The direction of the middle arrow indicates the direction of refrigerant flow.

[0047] Continue to combine Figure 6 The refrigeration system also includes an ice-melting valve 36. When the ice-making cycle ends, the ice-melting valve 36 is opened, and the refrigerant flows along... Figure 6 The red arrow indicates that the ice flows into evaporator 32, causing the ice surface to melt slightly and achieving automatic de-icing.

[0048] Example 3 In this embodiment, air cooling is used to provide cooling to the cold cup area 11.

[0049] like Figure 9 As shown, the refrigeration system in this embodiment is described in Embodiment 2. Figure 6 Based on the diagram, an auxiliary evaporator 39 is added. The auxiliary evaporator 39 is connected in series on the refrigerant pipe 31 between the capillary tube 35 and the main evaporator (to distinguish it from the auxiliary evaporator 39, the original evaporator 32 is defined as the main evaporator). For example... Figure 10As shown, the auxiliary evaporator 39 is located in the channel 5, which communicates with the cold cup area 11. The channel 5 also contains a fan 4 for delivering the cooling energy generated by the auxiliary evaporator 39 into the cold cup area 11. In this embodiment, through the cooperation of the fan 4 and the auxiliary evaporator 39, the fan 4 transfers the cooling energy of the auxiliary evaporator 39 from the channel 5 to the cold cup area 11, achieving a cold cup effect without affecting the normal ice-making process of the main evaporator. The design is ingenious, and the cold cup effect is excellent.

[0050] The fan 4 can be a blower 4 or a suction fan 4. One end of the channel 5 is connected to the cold cup area 11, and the other end of the channel 5 is an open opening connecting to the outside. Figure 10 As shown, when the fan 4 is a blower 4, it is located at the open end and is used to blow air onto the auxiliary evaporator 39 to transfer the cold energy to the cold cup area 11 through the channel 5. Figure 10 The direction of the middle arrow indicates the direction of airflow. When the fan 4 is a suction fan 4, it is located in the channel 5 between the auxiliary evaporator 39 and the cold cup area 11, and is used to draw the cold energy generated by the auxiliary evaporator 39 into the cold cup area 11.

[0051] Furthermore, such as Figure 11 As shown, a sealing cover 14 is provided on the cold cup area 11. When the sealing cover 14 is closed, it can form a sealed space in the cold cup area 11. When the sealing cover 14 is open, the cup 10 can be taken out and put in. By setting the sealing cover 14, not only can the cup 10 be kept clean when closed and the cup 10 be easily taken out and put in when open, but the cold cup area 11 can also form a closed space connected to the channel 5, so that the cold energy is retained in the cold cup area 11, preventing the cold energy from being lost and improving the cold cup effect.

[0052] Hot and cold coffee machines can also include a controller (not shown in the image). For example... Figure 11 As shown, a temperature sensor 6 can also be installed in the cold cup zone 11. Both the temperature sensor 6 and the fan 4 are connected to the controller. The temperature sensor 6 detects the temperature of the cold cup zone 11 and sends the detected temperature signal to the controller. The controller receives the temperature signal and controls the fan 4 to start and stop based on the temperature signal. Specifically, when the temperature of the cold cup zone 11 detected by the temperature sensor 6 is higher than the set value, the temperature sensor 6 sends a first signal to the controller, and the controller controls the fan 4 to turn on, transferring the cooling capacity of the auxiliary evaporator 39 to the cold cup zone 11. When the temperature of the cold cup zone 11 detected by the temperature sensor 6 reaches the set value, the temperature sensor 6 sends a second signal to the controller, and the controller controls the fan 4 to stop. In this way, the temperature of the cold cup zone 11 can be precisely controlled to achieve the best cold cup effect.

[0053] Continue to combine Figure 11The cold cup area 11 may also be equipped with a UV lamp 7 (ultraviolet lamp). When the sealing cover 14 is closed, the UV lamp 7 is triggered to start working, and when the sealing cover 14 is opened, the trigger on the UV lamp 7 is released, causing the UV lamp 7 to turn off and stop working. When the UV lamp 7 starts working, it is used to sterilize and disinfect the cups 10 in the cold cup area 11 to improve hygiene and safety.

[0054] For example, the switch for controlling the opening and closing of the UV lamp 7 is located at the edge of the cold cup area 11. When the sealing cover 14 is closed, the switch is pressed down to turn on the UV lamp 7. When the sealing cover 14 is opened, the sealing cover 14 disengages from the switch, and the switch pops up to turn off the UV lamp 7.

[0055] like Figure 12 As shown, the top cover 13 of the main body 1 is partially recessed to form a cup warming area 12. The heating pot 8 is located below the cup warming area 12, and a baffle 9 is provided around the heating pot 8 to collect the heat generated by the heating pot 8 and allow the heat to radiate upwards to the cup warming area 12. In this way, the heat from the heating pot 8 can be quickly and effectively transferred to the cup warming area 12 to achieve the effect of warming the cup.

[0056] When the coffee machine is powered on, the heating pot 8 is in preheating mode. The top cover 13 of the coffee machine generates a high-temperature area corresponding to the heating pot 8. Setting this area as the cup warming area 12 can effectively utilize the heat of the heating pot 8 to achieve the effect of warming the cup.

[0057] It is understandable that the cold cup area 11 and the warm cup area 12 can be located in suitable positions on the body 1 of the coffee machine according to actual needs, and are not limited to... Figure 1 The top of the main body 1. In addition, the cold cup area 11 and the warm cup area 12 can be arranged side by side or far apart from each other.

[0058] like Figure 1 As shown, as a preferred embodiment, the top cover 13 of the body 1 is recessed downwards to form two parallel cold cup areas 11 and warm cup areas 12. This effectively utilizes the space at the top of the body 1 and makes it convenient for users to place and remove cups 10. Lids can be provided on the cold cup area 11 and the warm cup area 12 to prevent the loss of cold and heat, thus improving the effectiveness of both.

[0059] This embodiment cleverly utilizes the evaporator 32 and heating element 8 of the refrigeration system to create a cold cup area 11 and a warm cup area 12 on the main body 1. This allows the cups 10 stored within to be used as cold and warm cups respectively. Hot coffee is extracted using the cups 10 in the warm cup area 12, while iced coffee is extracted using the cups 10 in the cold cup area 11, thus maintaining the taste of coffee at different temperatures. Furthermore, it is simple to operate, convenient to handle, and readily available.

[0060] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
