Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to a dual-purpose machine with brewing and baking functions. BACKGROUND

[0002] Coffee machines and tea infusers are household appliances with brewing functions, which are widely used in homes or commercial places. Among them, the coffee machine is an automatic brewing appliance that can realize functions such as grinding, pressing, loading, brewing, and cleaning residues.

[0003] Air fryers and ovens are household appliances with baking functions, which are widely used in homes. Among them, the air fryer is a kitchen cooking appliance that can use air to "fry". Its main principle is to use high-speed air circulation technology to replace the hot oil in the traditional frying pan with rapidly circulating hot air to cook the food in the air fryer. At the same time, the hot air generated can also blow away the water on the surface of the food, forming a crispy surface layer on the surface of the food, locking the water inside the food to achieve a cooking effect similar to frying.

[0004] At present, consumers attach great importance to kitchen space, so the volume of kitchen appliances is also increasingly valued. Therefore, the appliance itself is required to be small in size and multifunctional, so household appliances similar to breakfast machines have appeared, which combine ovens and coffee machines. For example, Chinese patent ZL201920151973.3, a breakfast machine, includes an oven assembly, a coffee machine assembly, and a frying pan. The oven assembly includes an inner box, an outer box, an electric heating tube group, and a box door. The inner box is arranged in the outer box, and the box door is pivotally connected to the outer box. The electric heating tube group is arranged in the inner box. The outer box top is provided with a frying pan clamping hole, and the inner box top is provided with a heat radiation hole. The frying pan is clamped in the frying pan clamping hole. The coffee machine assembly is fixed on one side of the outer box. This kind of breakfast machine has the functions of oven, frying pan and coffee machine. The user can conveniently bake food, fry food and make coffee at the same time, and the operation is simple and convenient. In addition, the frying pan is clamped in the frying pan clamping hole, so that the frying pan can use the heat of the oven assembly to fry food, improving the energy utilization efficiency. In the above technical solution, a method for frying food by using the heat of the oven assembly through the frying pan is provided to improve the energy utilization efficiency.

[0010] Therefore, by arranging the first heat dissipation port corresponding to the water storage tank in communication with the heat dissipation cavity, the hot air blown out from the heat dissipation cavity is guided to the surface of the water storage tank through the first heat dissipation port, thereby heating the water storage tank, and the water stored in the water storage tank is preheated through the heat conduction of the water storage tank, thereby reducing the heating power of the water body and thus reducing the heating energy consumption when the brewing machine uses the water in the water storage tank and reheats the water body, thereby achieving energy saving of the brewing machine in use. At the same time, the air temperature in the heat dissipation cavity is higher than that of normal temperature air, so that the hot air in the heat dissipation cavity is used to preheat the water stored in the water storage tank, which not only realizes the reuse of the heat energy that needs to be directly discharged originally, thereby further achieving energy saving, but also preheats the water stored in the water storage tank, thereby accelerating the heating speed of the brewing machine, thereby facilitating the opening speed of the brewing machine.

[0011] In one embodiment, a communication hole is arranged between the installation cavity and the heat dissipation cavity, the heat dissipation cavity is in communication with a second heat dissipation port, and the heat dissipation cavity is communicated to the outside of the machine shell through the second heat dissipation port;

[0012] The air in the installation cavity enters the heat dissipation cavity through the communication hole and is discharged to the outside of the machine shell through the second heat dissipation port.

[0013] In one embodiment, the heat dissipation cavity is in the shape of a disc, and radial flow fan blades are arranged in the heat dissipation cavity, and a first heat dissipation channel and a second heat dissipation channel are respectively arranged in the side wall of the heat dissipation cavity, wherein:

[0017] In one embodiment, the first heat dissipation passage comprises a first flow guide wall formed on the heat dissipation cover, the first flow guide wall intersects with the heat dissipation cavity and is arranged in a circular arc shape to guide the hot air blown from the heat dissipation cavity to flow along the surface of the first flow guide wall to the surface of the water storage tank.

[0018] In one embodiment, the second heat dissipation passage comprises a third flow guide wall and a fourth flow guide wall, the third flow guide wall is tangentially arranged with the heat dissipation cavity, and the fourth flow guide wall is arranged in a circular arc shape.

[0019] In one embodiment, the heat dissipation cover is provided with a driving motor and a wind shield, the driving motor is in transmission connection with the radial fan blade, and the wind shield is arranged outside the driving motor.

[0020] In one embodiment, the second heat dissipation passage comprises a wind guide section in communication with the heat dissipation cavity and a diameter expansion section in communication with the outside of the machine shell, the width of the diameter expansion section is greater than that of the wind guide section.

[0021] In one embodiment, the water tank comprises a first side wall and a second side wall arranged adjacently, a flow guide corner in a circular arc shape is arranged between the first side wall and the second side wall.

[0023] In one embodiment, the water storage tank is made of plastic material or metal material.

[0024] In summary, the present invention has the following advantages: by arranging the first heat dissipation port connected to the heat dissipation chamber in correspondence with the water storage tank, the hot air blown out from the heat dissipation chamber is guided to blow to the surface of the water storage tank through the first heat dissipation port to heat the water storage tank, thereby preheating the water stored in the water storage tank through the heat conduction of the water storage tank. When the brewing machine uses the water in the water storage tank and reheats the water, it can reduce the heating power of the water and thus reduce the heating energy consumption, thereby saving energy when the brewing machine is in use. At the same time, the air temperature in the heat dissipation chamber is higher than the temperature of the air at room temperature. Therefore, using the hot air from the heat dissipation chamber to preheat the water stored in the water storage tank can not only reuse the heat energy that originally needs to be directly discharged, further saving energy, but also preheating the water stored in the water storage tank can speed up the heating speed of the water in the brewing machine, thereby facilitating the speed of boiling water in the brewing machine.

DETAILED DESCRIPTION

[0031] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] See Figure 1 As shown, the present invention provides a dual-purpose machine with brewing and baking functions, including a housing 100, on which are mounted a brewing machine 200 with a brewing function and a baking machine 300 with a baking function, thereby satisfying both the user's brewing and baking needs, achieving dual purposes. The brewing machine 200 is a coffee machine or a tea machine. In this embodiment, the brewing machine 200 is a coffee machine, specifically an espresso machine. The baking machine 300 is an air fryer or an oven. In this embodiment, the baking machine 300 is an air fryer.

[0035] Among them, combined Figures 2-5 As shown, a mounting cavity 4 is provided within the housing 100. The brewing machine 200 includes a water tank 5 disposed within the mounting cavity 4. The water tank 5 is used to store water to provide brewing water for the brewing machine 200. Furthermore, the toaster 300 includes a heat dissipation cavity 6 and a first heat dissipation vent 71 disposed within the mounting cavity 4. During use, some of the heat generated by the toaster 300 is collected within the heat dissipation cavity 6 and discharged as hot air through the first heat dissipation vent 71, thereby achieving heat dissipation for the toaster 300. Specifically, the heat collected within the heat dissipation cavity 6 includes heat radiation from the toaster cavity and / or heat generated by the toaster 300 drive motor 13.

[0036] Among them, the first heat dissipation port 71 is connected to the heat dissipation cavity 6 and the first heat dissipation port 71 is set corresponding to the water tank 5, so that the hot air blown out from the heat dissipation cavity 6 can be guided to blow to the surface of the water tank 5 through the first heat dissipation port 71 to heat the water tank 5, and then the water stored in the water tank 5 is preheated through the heat conduction of the water tank 5.

[0037] It can be seen that the first heat dissipation opening 71 corresponding to the water storage tank 5 is arranged in communication with the heat dissipation cavity 6 to guide the hot air blown out of the heat dissipation cavity 6 to the surface of the water storage tank 5 through the first heat dissipation opening 71 to heat the water storage tank 5, so that the water stored in the water storage tank 5 is preheated through heat conduction of the water storage tank 5, and when the brewing machine 200 uses the water in the water storage tank 5 and reheats the water, the heating power of the water can be reduced to reduce the heating energy consumption and save the energy consumption of the brewing machine 200 in use. At the same time, the air temperature in the heat dissipation cavity 6 is higher than that of normal temperature air, so that the hot air in the heat dissipation cavity 6 is used to preheat the water stored in the water storage tank 5, which not only realizes the reuse of the heat energy that needs to be directly discharged, but also further saves energy consumption, and preheats the water stored in the water storage tank 5, which can speed up the heating speed of the brewing machine 200, thereby facilitating the speed of the brewing machine 200 to open water.

[0038] In order to further illustrate the actual effect of the present application, the inventor tests that the hot air blown out of the heat dissipation cavity 6 can generally reach more than 70 degrees, and generally can reach 80 degrees, and after a certain preheating time, the water stored in the water storage tank 5 can generally reach more than 50 degrees, and generally can reach 60 degrees, so that the water heating energy consumption between normal temperature and 50 degrees can be reduced, and the energy consumption of the brewing machine 200 in use can be saved. At the same time, not only can the 70-degree hot air that needs to be directly discharged be reused to further save energy consumption, but also the brewing machine 200 only needs to reheat the 50-degree water stored in the water storage tank 5, which can speed up the heating speed of the brewing machine 200, thereby facilitating the speed of the brewing machine 200 to open water.

[0039] In actual use, since the baking time of food is generally longer, and the brewing time of beverage is generally shorter. Therefore, the user can first bake food through the baking machine 300, and then use the brewing machine 200 to make beverage after a period of baking. In this way, the heat dissipation cavity 6 has enough time to heat the water in the water storage tank 5, so that the preheating effect can be better achieved.

[0040] The hot air blown in the heat dissipation cavity 6 needs to be discharged to the outside of the machine shell 100 after blowing on the surface of the water storage tank 5. Preferably, a single channel is used to set a flow channel connected with the first heat dissipation port 71 to re-flow and discharge the hot air blown on the surface of the water storage tank 5 to the outside of the machine shell 100. The above-mentioned method has the following problems: first, the original heat dissipation structure needs to be greatly changed; second, if the flow channel is directly connected to the outside of the machine shell 100, the heat exchange time of the hot air with the water storage tank 5 will be short, reducing the utilization rate of the heat energy of the hot air; if the flow channel is laid along the side wall of the water storage tank 5, the heat exchange time of the hot air with the water storage tank 5 can be prolonged, and the utilization rate of the heat energy of the hot air can be improved, but the length of the flow channel is increased, so more materials are needed, thereby increasing the production cost.

[0041] The hot air blown in the heat dissipation cavity 6 needs to be discharged to the outside of the machine shell 100 after blowing on the surface of the water storage tank 5. Preferably, a single channel is used to set a flow channel connected with the first heat dissipation port 71 to re-flow and discharge the hot air blown on the surface of the water storage tank 5 to the outside of the machine shell 100. The above-mentioned method has the following problems: first, the original heat dissipation structure needs to be greatly changed; second, if the flow channel is directly connected to the outside of the machine shell 100, the heat exchange time of the hot air with the water storage tank 5 will be short, reducing the utilization rate of the heat energy of the hot air; if the flow channel is laid along the side wall of the water storage tank 5, the heat exchange time of the hot air with the water storage tank 5 can be prolonged, and the utilization rate of the heat energy of the hot air can be improved, but the length of the flow channel is increased, so more materials are needed, thereby increasing the production cost.

[0042] The water tank comprises the first side wall 51 and the second side wall 53 which are arranged adjacently, and the flow guide angle 52 in the form of a circular arc is arranged between the first side wall 51 and the second side wall 53 for guiding the hot air flow, that is, a circular arc angle is arranged between the first side wall 51 and the second side wall 53. Further, the first heat dissipation opening 71 is arranged corresponding to the first side wall 51 and / or the first heat dissipation opening 71 is arranged corresponding to the flow guide angle 52. In this way, the circular arc flow guide angle 52 is designed, which not only avoids the blockage of the hot air flow when the first side wall 51 and the second side wall 53 are arranged at a right angle, but also utilizes the Coanda effect by arranging the circular arc, so that when the hot air flows on the surface of one of the side walls, it can flow along the surface of the flow guide angle 52 to the surface of the other side wall through the guidance of the flow guide angle 52, thereby effectively extending the time of heat exchange between the hot air and the water tank 5 without arranging a flow channel, improving the utilization rate of the heat energy of the hot air, effectively reducing the use of materials, and being conducive to reducing the production cost of the product. In addition, due to the limitation of the volume of the electric appliance, the space in the mounting cavity 4 is limited, and the angle of the first heat dissipation opening 71 corresponding to the water tank 5 is easily limited. In this way, the flow of the hot air can be guided as needed by arranging the flow guide angle 52, the angle requirement of the first heat dissipation opening 71 corresponding to the water tank 5 is reduced, and the flexibility of the internal structure design of the product is improved.

[0043] For example, in one embodiment, the first heat dissipation opening 71 is arranged corresponding to the first side wall 51, and the hot air can form the following flow direction: after the hot air hits the surface of the first side wall 51, it flows towards the flow guide angle 52 and flows along the surface of the flow guide angle 52 to the surface of the second side wall 53; or after the hot air hits the surface of the first side wall 51, it is divided into two air flows, the first air flow flows along the surface of the first side wall 51 towards the flow guide angle 52 and flows along the surface of the flow guide angle 52 to the surface of the second side wall 53, and the second air flow flows along the surface of the first side wall 51 away from the flow guide angle 52. In another embodiment, the first heat dissipation opening 71 is arranged corresponding to the flow guide angle 52, and the hot air can form the following flow direction: after the hot air hits the surface of the flow guide angle 52, it is divided into two air flows, the first air flow flows towards the surface of the first side wall 51, and the second air flow flows towards the surface of the second side wall 53. In this embodiment, the first heat dissipation opening 71 is arranged corresponding to the first side wall 51 and the flow guide angle 52, and the hot air can form the flow direction shown in FIG. X. Other hot air flow directions are not listed here.

[0044] The heat dissipation cavity 6 is in the shape of a disc, and the inside of the heat dissipation cavity 6 is provided with radial flow fan blades 11. When the radial flow fan blades 11 rotate, the hot air is blown to the side wall of the heat dissipation cavity 6 due to the lateral air outlet of the radial flow fan blades 11. Further, the side wall of the heat dissipation cavity 6 is respectively communicated with the first heat dissipation channel 7 and the second heat dissipation channel 8, so that the hot air on the side wall enters the first heat dissipation channel 7 and the second heat dissipation channel 8 respectively. Further, the first heat dissipation channel 7 has a first heat dissipation port 71 and is intersected with the heat dissipation cavity 6, and the second heat dissipation channel 8 has a second heat dissipation port 81 and is tangent to the heat dissipation cavity 6. In this way, the air flow entering the first heat dissipation channel 7 is relatively large, so that more hot air is blown to the surface of the water storage tank 5, and the air flow entering the second heat dissipation channel 8 is relatively small, so that the hot air is relatively less, thereby prolonging the time of the hot air and improving the utilization rate of the heat energy of the hot air.

[0045] The baking machine 300 further comprises a heat dissipation cover 12 arranged in the mounting cavity 4, and the inside of the heat dissipation cover 12 is formed with the heat dissipation cavity 6, the first heat dissipation channel 7 and the second heat dissipation channel 8, that is, the heat dissipation cavity 6, the first heat dissipation channel 7 and the second heat dissipation channel 8 are formed by the heat dissipation cover 12. In actual production, the heat dissipation cover 12 can be integrally formed by stamping or casting process, so as to form the heat dissipation cavity 6, the first heat dissipation channel 7 and the second heat dissipation channel 8 in the heat dissipation cover 12.

[0046] The first heat dissipation channel 7 comprises a first flow guide wall 72 and a second flow guide wall 73 formed on the heat dissipation cover 12, and the first flow guide wall 72 and the second flow guide wall 73 are intersected with the heat dissipation cavity 6. Further, the first flow guide wall 72 is in the shape of an arc, so as to guide the hot air blown from the heat dissipation cavity 6 to flow along the surface of the first flow guide wall 72 to the surface of the water storage tank 5. In this way, the hot air is not only better guided to enter the first heat dissipation channel 7 to increase the air flow of the first heat dissipation channel 7, but also makes the hot air on the side wall of the heat dissipation cavity 6 enter the first heat dissipation channel 7 more gently, thereby reducing the wind noise.

[0047] The second heat dissipation channel 8 includes a third flow guide wall 82 and a fourth flow guide wall 83 formed on the heat dissipation cover 12, the third flow guide wall 82 is tangent to the heat dissipation cavity 6, and the fourth flow guide wall 83 is arranged in a circular arc shape. In this way, even if the second heat dissipation channel 8 is not ventilated, the hot air entering the second heat dissipation channel 8 is not easy to flow back to the heat dissipation cavity 6 through the fourth flow guide wall 83. Further, the second heat dissipation channel 8 includes a wind guide section 84 communicating with the heat dissipation cavity 6 and a diameter expansion section 85 communicating to the outside of the cabinet 100, and the width of the diameter expansion section 85 is greater than that of the wind guide section 84. In this way, by arranging the diameter expansion section 85, not only the hot air in the second heat dissipation channel 8 is better discharged to the outside of the cabinet 100, but also the hot air entering the second heat dissipation channel 8 is not easy to flow back to the heat dissipation cavity 6.

[0048] The heat dissipation cover 12 is provided with a driving motor 13 and a baffle 14, the driving motor 13 is in transmission connection with the radial fan blade 11, and the baffle 14 is arranged outside the driving motor 13. The arranged baffle 14 can block the hot air blown to the surface of the water storage tank 5 from directly flowing back to the driving motor 13 in the lateral direction, thereby avoiding the hot air reaching 70 degrees of high temperature from directly blowing to the driving motor 13, so that the hot air can only diffuse and cool down in the mounting cavity 4 and then blow to the driving motor 13 in the vertical direction to cool the driving motor 13, thereby effectively protecting the driving motor 13. At the same time, the arranged baffle 14 can also form a converging flow effect in the vertical direction, forming the following air flow direction: the air in the mounting cavity 4 first flows into the area surrounded by the baffle 14, and because the volume of the area surrounded by the baffle 14 is small, the negative pressure generated in the heat dissipation cavity 6 can better cause the air in the surrounded area to be sucked into the heat dissipation cavity 6 through the communication hole 9, thereby realizing the converging flow effect.

[0049] The water storage tank 5 can be made of plastic material or metal material. The thermal conductivity of the plastic material is relatively poor, but the heat preservation effect is good, and the thermal conductivity of the metal material is relatively good, but the heat preservation effect is poor, each has advantages and disadvantages. However, because the time for roasting food is generally long, the water storage tank 5 can be provided with a longer heating time, so there is no need to worry about the problem of insufficient heating temperature, and the plastic material with better heat preservation effect is used to prepare the water storage tank 5, which has better use effect. Specifically, in the embodiment, the water storage tank 5 is made of PP plastic material.

[0050] The technical means disclosed in the present application is not limited to the technical means disclosed in the above embodiment, but also includes the technical solutions composed of any combination of the above technical features. It should be noted that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can also be made, which are also considered within the scope of protection of the present application.
