Description

Technical Field

[0001] The invention relates to the technical field of steaming and baking cooking machines, in particular to an exhaust component and a steaming and baking cooking machine. Background Art

[0002] Most built-in steamers on the market use a front exhaust solution. A plastic air guide plate is designed inside the cavity to discharge the steam generated during cooking from the front of the machine. At this time, due to the low temperature of the air guide system, the steam will condense in the air guide channel during the exhaust process to produce condensed water. Since the built-in machine is installed in a cabinet, if the condensed water is not handled, there will be an odor inside the air guide plate in a humid environment for a long time, which will reduce the user experience. Summary of the invention

[0003] Since the condensed water remaining on the air guide plate of the existing steam-bake cooking machine easily causes odor problems and affects the user experience, it is necessary to provide an exhaust assembly and a steam-bake cooking machine.

[0004] The exhaust assembly is used to exhaust the steam in the inner tank assembly, including:

[0005] An air guide structure, the air guide structure having a condensation water chamber and an exhaust passage connected to the condensation water chamber and an external space;

[0006] An exhaust joint, one end of which is connected to the condensed water chamber, and the other end of which is used to connect to the inner tank assembly; and

[0007] a fan, the fan being disposed in the exhaust passage and used to exhaust the gas in the exhaust passage; and

[0008] A heating element is arranged in the exhaust joint and is used to heat the gas entering the exhaust joint to dry the condensed water in the condensed water chamber.

[0009] With such a configuration, by adding an exhaust joint with a built-in heating element, the steam-bake cooking machine has a drying function, thereby eliminating condensed water on the air guide structure, which is beneficial to keeping the air guide structure dry and reducing the generation of odor.

[0010] In one embodiment, the condensation water chamber comprises a condensation chamber and a heating chamber respectively connected to the exhaust passage, and the heating chamber surrounds the condensation chamber for transferring heat to the condensation chamber;

[0011] The exhaust joint has a first air inlet passage connected to the condensing chamber and a second air inlet passage connected to the heating chamber;

[0012] The exhaust assembly further includes a damper provided in the exhaust joint, and the damper is used to block the first air inlet passage or the second air inlet passage.

[0013] With such arrangement, the hot gas generated after being heated by the heating element can fully exchange heat with the condensed water in the condensation chamber, thereby shortening the drying time.

[0014] In one embodiment, the air damper includes a driving member and a baffle rotatably mounted in the exhaust joint, the baffle cover is arranged at the entrance of the first air inlet channel or the entrance of the second air inlet channel, and the driving member is driven and connected to the baffle so that the baffle switches between two states of blocking the first air inlet channel and blocking the second air inlet channel.

[0015] With such an arrangement, the rotation of a single baffle is coordinated with the mode switching of the steam-bake cooking machine to ensure that gas enters a preset cavity. The structure is simple and blockage of the airflow path is avoided.

[0016] In one of the embodiments, the baffle includes a rotating shaft, a plate body fixedly connected to the rotating shaft, and a gear fixedly connected to the rotating shaft, the driving member includes a guide cylinder installed in the exhaust joint and open at only one end, and a piston rod slidably inserted in the guide cylinder, one end of the piston rod is provided with meshing teeth matching the gear, and the other end is sealed in the guide cylinder to form an expansion space in the guide cylinder; the heating member is heat-transferably connected to the guide cylinder to expand the expansion space for pushing the piston rod.

[0017] With this arrangement, the automatic rotation of the baffle is achieved by utilizing the technical condition that the exhaust joint temperature is relatively high in the drying mode of the steam-bake cooking machine. No manual adjustment or complex and easily damaged electronic components are required, thereby increasing the intelligence and adaptability of the steam-bake cooking machine in mode switching.

[0018] In one embodiment, the piston rod includes a plug body slidably sealed in the guide tube and a rod body extending axially from the plug body, the driving member also includes a reset spring sleeved on the rod body, and the opening of the guide tube is also provided with a stop block, one end of the reset spring abuts against the plug body of the piston rod, and the other end abuts against the stop block.

[0019] Such an arrangement can prevent the baffle from being unable to rotate due to the piston rod getting stuck when retracting, thereby ensuring that the first air inlet channel can always remain open when the steam-bake cooking machine is in cooking mode.

[0020] In one of the embodiments, the air guide structure further has a connecting channel connected to the condensation chamber and the heating chamber.

[0021] With such an arrangement, hot gas enters the condensation chamber from the connecting channel and comes into direct contact with the condensed water, which also speeds up the air flow speed in the condensation chamber, further improving the drying effect of the condensed water.

[0022] In one embodiment, the air guide structure includes a mounting plate and an air guide cover fixed under the mounting plate, a notch is provided at the edge of the air guide cover to form the exhaust passage together with the mounting plate, the air guide cover is partially sunken to form the condensation water chamber, an open box is constructed in the condensation water chamber and the open end of the open box is ring-connected to the open end of the condensation water chamber to form the condensation chamber and the heating chamber, and the connecting passage is provided on the side wall of the open box.

[0023] With such arrangement, the open box for providing the condensation chamber has no obstruction to the evaporation of condensed water, and the evaporated condensed water can be blown away and carried away in time when the hot gas flows out from the connecting channel, thereby avoiding the accumulation of steam in the exhaust channel.

[0024] In one embodiment, the side of the condensation water chamber has a give-way angle, and the outlet of the first air inlet channel and the outlet of the second air inlet channel are located at the give-way angle.

[0025] In this way, the make way angle is not only used to make way for the installation of the exhaust joint, thereby optimizing the internal space layout of the steam-bake cooking machine, but also provides installation space for the first air pipe for providing the first air intake channel and the second air pipe for providing the second air intake channel.

[0026] In one embodiment, the inner diameter of the second air inlet passage is smaller than the inner diameter of the first air inlet passage.

[0027] Such a setting is conducive to ensuring the stability of the hot air flow velocity, thereby achieving stable heat exchange between the hot gas in the heating chamber and the condensed water in the condensation chamber, which is conducive to accurately calculating the drying time.

[0028] The present application also provides a steaming and baking cooking machine, comprising:

[0029] An inner tank assembly having an exhaust port; and

[0030] As in the above-mentioned exhaust assembly, the air guide structure of the exhaust assembly is installed on the bottom wall of the inner tank assembly, and the exhaust joint of the exhaust assembly is connected to the exhaust port.

[0031] With such a configuration, the exhaust assembly is located below the inner tank assembly, which increases the distance between the lower heating tube and the cabinet, thereby reducing the temperature rise of the cabinet used to support the steam-bake cooking machine, ensuring the low temperature comfort of the exhaust hole at the front end of the machine during normal operation, and ensuring the dryness and temperature rise of the exhaust system when the machine finishes working, thereby improving the user experience and safety of the machine.

[0046] Most built-in steamers on the market use a front exhaust solution. A plastic air guide plate is designed inside the cavity to discharge the steam generated during cooking from the front of the machine. At this time, due to the low temperature of the air guide system, the steam will condense in the air guide channel during the exhaust process to produce condensed water. Since the built-in machine is installed in a cabinet, if the condensed water is not handled, there will be an odor inside the air guide plate in a humid environment for a long time, which will reduce the user experience.

[0047] Based on this, it is necessary to provide an exhaust assembly and a steam-bake cooking machine that can eliminate condensed water on the air guide plate.

[0048] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of the steaming and baking cooking machine provided in this application. Figure 2 for Figure 1 The steam-bake cooking machine provided by the present application comprises an inner tank assembly 60 and an exhaust assembly, wherein the exhaust assembly is located below the inner tank assembly 60, thereby increasing the distance between the lower heating pipe and the cabinet, thereby reducing the temperature rise of the cabinet used to support the steam-bake cooking machine, ensuring the low temperature comfort of the exhaust hole at the front end of the machine during normal operation, and ensuring the dryness and temperature rise of the exhaust system when the machine is finished working, thereby improving the user experience and safety of the machine.

[0049] The exhaust assembly provided in the present application is used to exhaust the steam in the inner tank assembly 60, and the exhaust assembly includes an air guide structure 10, an exhaust joint 20, a fan 30 and a heating element 40. The air guide structure 10 has a condensate water chamber 101 and an exhaust channel 102 connected to the condensate water chamber 101 and the external space. One end of the exhaust joint 20 is connected to the condensate water chamber 101, and the other end is used to connect to the inner tank assembly 60. The fan 30 is arranged in the exhaust channel 102 and is used to exhaust the gas in the exhaust channel 102. The heating element 40 is arranged in the exhaust joint 20 and is used to heat the gas entering the exhaust joint 20 to dry the condensate in the condensate water chamber 101. During the steaming and baking process of the steam-bake cooking machine, the evaporation plate in the inner pot assembly 60 continuously generates steam. When the heat exchange between the steam and the food is completed, under the negative pressure of the fan 30, the steam is continuously drawn from the inner pot body to the air guide structure 10 and condensed into condensed water in the air guide structure 10. When the steam-bake cooking machine finishes cooking, the fan 30 still keeps working and the heating element 40 starts working. At this time, the temperature in the exhaust joint 20 continues to rise, so that the gas passing through the exhaust joint 20 can be heated. When the hot air is blown from the exhaust joint 20 to the air guide structure 10, the condensed water remaining in the air guide structure 10 can be evaporated and taken away, which is beneficial to keep the air guide structure 10 dry and reduce the generation of odor.

[0050] Specifically, the air guide structure 10 includes a mounting plate 11, an air guide cover 12 fixed under the mounting plate 11, a notch is provided at the edge of the air guide cover 12 to form an exhaust passage 102 with the mounting plate 11, and the air guide cover 12 is partially sunken to form a condensed water chamber 101. Therefore, in this embodiment provided by the present application, the mass of the condensed water can also be calculated by measuring the height of the condensed water in the condensed water chamber 101, and the drying time required to dry the condensed water can be determined in conjunction with the heating power of the heating element 40. Considering the heat loss during drying, the corresponding compensation coefficient needs to be matched when calculating the drying time. According to experiments, the compensation coefficient is 1.5, that is, the drying time calculated based on the power of the heating element 40, the mass of the condensed water and the specific heat capacity of water needs to be multiplied by the compensation coefficient to obtain the actual drying time.

[0051] See also Figures 3 to 6 , Figure 3 This is a schematic structural diagram of a steaming and baking cooking machine in another embodiment provided in the present application. Figure 4 for Figure 3 The cross-sectional view of the steam-bake cooking machine taken along the AA direction is shown. Figure 5 for Figure 3 The bottom structure diagram of the steaming and baking cooking machine is shown in FIG. Figure 6 for Figure 5 Cross-sectional view of the exhaust connector in the BB direction.

[0052] Furthermore, in order to shorten the drying time, in another embodiment provided in the present application, the condensation water chamber 101 includes a condensation chamber 1011 and a heating chamber 1012 respectively connected to the exhaust channel 102, the heating chamber 1012 surrounds the condensation chamber 1011 and is used to transfer heat to the condensation chamber 1011, the exhaust connector 20 has a first air inlet channel 201 connected to the condensation chamber 1011 and a second air inlet channel 202 connected to the heating chamber 1012, the exhaust assembly also includes a wind valve 50 arranged in the exhaust connector 20, the wind valve 50 is used to block the first air inlet channel 201 or the second air inlet channel 202. When the steam-bake cooking machine is in the cooking mode, the air damper 50 blocks the second air inlet channel 202, at which time the gas is introduced into the condensing chamber 1011 and the steam in the gas condenses when it is cold; when the steam-bake cooking machine is in the drying mode, the air damper 50 blocks the first air inlet channel 201, at which time the hot gas generated by the heating element 40 enters the heating chamber 1012 from the second air inlet channel 202. Since the heating chamber 1012 surrounds the condensing chamber 1011, the hot gas can fully exchange heat with the condensed water in the condensing chamber 1011, thereby shortening the drying time. Optionally, in one embodiment provided in the present application, in order to ensure the stability of the hot air flow rate in the drying mode, the inner diameter of the second air inlet channel 202 is smaller than the inner diameter of the first air inlet channel 201.

[0053] See also Figure 4 Optionally, in one embodiment provided in the present application, an open box 13 is constructed in the condensation water chamber 101, and the open end of the open box 13 is connected to the open end of the condensation water chamber 101 to form a condensation chamber 1011 and a heating chamber 1012, and a connecting channel 103 is opened on the side wall of the open box 13. In the drying mode, the hot gas enters the condensation chamber 1011 from the connecting channel 103 and directly contacts the condensation water, which also speeds up the air flow speed in the condensation chamber 1011, further improving the drying effect of the condensation water.

[0054] Please also read Figures 4 to 6. Specifically, in an embodiment provided in the present application, the air damper 50 includes a driving member 51 and a baffle 52 rotatably installed in the exhaust joint 20, the baffle 52 covers the entrance of the first air inlet channel 201 or the entrance of the second air inlet channel 202, and the driving member 51 is driven to be connected to the baffle 52 so that the baffle 52 switches between blocking the first air inlet channel 201 and blocking the second air inlet channel 202, that is, corresponding to the switching of the cooking mode and the heating mode of the steam-bake cooking machine. The rotation of a single baffle 52 is coordinated with the mode switching of the steam-bake cooking machine to ensure that the gas enters the preset cavity, the structure is simple, and the blockage of the air flow path is avoided. In order to cooperate with the rotation of the baffle 52, the channel openings of the first air inlet channel 201 and the second air inlet channel 202 are arranged on the same side of the exhaust joint 20. Furthermore, no matter which mode the steam-bake cooking machine is in, the temperature of the exhaust joint 20 is always high and the humidity is high. If electromagnetic force is used to drive it, not only is the structure complicated, but the electronic components are easily damaged at high temperatures. The humidity in the exhaust joint 20 is also high, and it is easy for the electronic components to be damaged by water. If manual operation is used, automatic switching cannot be achieved and it is easy to scald the user. Based on this, in the present application, the baffle 52 includes a rotating shaft 521, a plate body 522 fixedly connected to the rotating shaft 521, and a gear 523 fixedly connected to the rotating shaft 521. The driving member 51 includes a guide cylinder 511 installed in the exhaust joint 20 and having only one end open, and a piston rod slidably inserted in the guide cylinder 511. 512, one end of the piston rod 512 is provided with a meshing tooth 513 cooperating with the gear 523, and the other end is sealed in the guide cylinder 511 to form an expansion space 5111 in the guide cylinder 511; the heating element 40 is heat-transferably connected to the guide cylinder 511 to expand the expansion space 5111 to push the piston rod 512. Specifically, the heating element 40 is a heating tube and is arranged around the guide cylinder 511 to increase the heat transfer effect. In this way, the baffle 52 is automatically rotated by utilizing the technical condition that the temperature of the exhaust joint 20 is relatively high in the drying mode of the steam-bake cooking machine, without manual adjustment or complex and easily damaged electronic components, thereby increasing the intelligence and adaptability of the steam-bake cooking machine in mode switching.

[0055] Furthermore, the piston rod 512 includes a plug body slidably sealed in the guide cylinder 511 and a rod body extending axially from the plug body. The driving member 51 also includes a return spring 514 sleeved on the rod body. The opening of the guide cylinder 511 is also provided with a stop block 53. One end of the return spring 514 abuts against the plug body of the piston rod 512, and the other end abuts against the stop block 53. In this way, the piston rod 512 can be prevented from getting stuck when retracting, causing the baffle 52 to be unable to rotate, thereby ensuring that the first air inlet channel 201 can always remain conductive when the steam-bake cooking machine is in the cooking mode.

[0056] Please refer again Figure 5Optionally, in an embodiment provided in the present application, the side of the condensed water chamber 101 has a folding angle 104, and the outlet of the first air inlet channel 201 and the outlet of the second air inlet channel 202 are located at the folding angle 104. The folding angle 104 is not only used to make room for the installation of the exhaust joint 20, thereby optimizing the internal space layout of the steam-bake cooking machine, but also provides installation space for the first air pipe for providing the first air inlet channel 201 and the second air pipe for providing the second air inlet channel 202.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
