Description

Technical Field

[0001] The present application relates to the field of steam ovens, and in particular to a fume condensation hood for a steam oven. Background Art

[0002] A steam oven is a kitchen appliance that can both steam and bake, allowing users to cook food in multiple ways using the same appliance, eliminating the need to purchase separate cooking devices, which increases costs and takes up too much space. Steam ovens produce smoke during use, which, especially when used indoors, can hinder the user's ability to accurately observe the cooking status of the food and can also have adverse effects on the user's health.

[0003] Therefore, in the prior art, a fan is provided in the steam oven. When the door of the steam oven is in a closed state, the fan can form a stable air duct in the steam oven, thereby sucking the smoke in the steam oven to the outside of the steam oven.

[0004] However, during the cooking process, if the user opens the door of the steam oven, the air duct formed by the fan in the steam oven will be affected, causing part of the smoke to flow outward rapidly from the door and directly hit the user's face, affecting the user's line of sight and resulting in a poor user experience. Summary of the Invention

[0005] In order to improve the problem that smoke will rush towards the user's face when the door of the steam oven is opened during use, the present application provides a smoke condensation hood for the steam oven.

[0006] The smoke condensation hood for a steam-baking oven comprises a shell, the outer wall of which is provided with a smoke inlet, an exhaust port and a cold air inlet, a smoke channel and a mixing channel being provided in the shell, the end of the smoke channel being connected with the front end of the mixing channel, the end of the mixing channel being connected with the exhaust port and being provided with a fan, the air inlet end of the fan facing the cold air inlet and the air outlet end facing the exhaust port; the smoke inlet is located at the bottom of the shell and is connected with the interior of the steam-baking oven, the smoke in the steam-baking oven enters the smoke channel through the smoke inlet and is discharged from the exhaust port; the cold air inlet is located above the door body of the steam-baking oven, the smoke overflowing when the door body of the steam-baking oven is opened and the external cold air enters the mixing channel through the cold air inlet and is discharged from the exhaust port.

[0007] By adopting the above technical solution, the fan will generate a negative pressure suction effect in the mixing channel, and the end of the smoke channel will be connected to the front end of the mixing channel. In this way, the smoke in the steam-bake oven will enter the smoke channel of the shell through the smoke inlet, flow toward the mixing channel, and finally be discharged from the exhaust port; when the door of the steam-bake oven is opened, the operating power of the fan is increased at the same time, so that the smoke and external cold air that overflow when the door of the steam-bake oven is opened will be sucked into the mixing channel through the cold air inlet located above the door of the steam-bake oven, and finally be discharged from the exhaust port.

[0008] Since the end of the smoke channel is connected with the front end of the mixing channel, the suction effect of the fan can form a stable airflow channel in both the smoke channel and the mixing channel, thereby ensuring that the smoke in the steam oven and the smoke overflowing when the door of the steam oven is opened can be sucked into the mixing channel and discharged in a centralized manner, effectively preventing the smoke overflowing from the steam oven from rushing towards the user's face when the door of the steam oven is opened, thereby interfering with the user's sight; at the same time, the inhalation of external cold air can promote the condensation of the smoke and purify the smoke.

[0009] Optionally, a pair of partitions are provided in the smoke channel, which cut off the smoke channel, and a number of condensing tubes are provided between the pair of partitions; the smoke in the smoke channel passes through the inside of the number of condensing tubes and enters the mixing channel, and the smoke overflowing when the door of the steam oven is opened, the external cold air and the smoke transferred from the smoke channel are mixed in the mixing channel and pass through the outside of the number of condensing tubes.

[0010] By adopting the above technical solution, the partition can partition the flue gas channel and can install and support the condenser, thereby ensuring that the flue gas in the steaming and baking can be completely transferred from the flue gas channel to the interior of the condenser, and after passing through the condenser, enter the mixing channel, thereby flowing in the mixing channel together with the external cold air, and finally discharged from the exhaust port.

[0011] Since a plurality of condensing tubes can provide a larger contact area for contacting with the flue gas, it is ensured that the steam in the flue gas can be completely condensed after passing through the condensing tubes, thereby improving the purification effect of the flue gas.

[0012] When the smoke in the steam oven is continuously generated and continuously passes through the smoke channel and the condenser, the temperature of the inner wall of the smoke channel and the inner wall of the condenser will increase, thereby reducing the condensation effect on the smoke. At this time, the external cold air will enter the mixing channel from the cold air inlet and cool the outer wall of the condenser tube and the outer wall of the smoke channel, thereby achieving a reduction in the overall temperature of the condenser tube and the smoke channel, thereby ensuring that the condensation effect on the smoke continues to be effective.

[0013] Optionally, an adjustment mechanism is provided in the shell, and the adjustment mechanism is used to adjust the relative positions between the plurality of condensing tubes and the external cold air.

[0014] By adopting the above technical solution, the position of the condenser tube can be adjusted under the action of the adjustment mechanism, so that the cooling effect of the external cold air on several condenser tubes is more uniform and the air cooling effect is more reliable. In this way, the condensation and purification effect of the flue gas is also more significant and continuous.

[0015] Optionally, the adjustment mechanism includes a hydraulic cylinder, a magnetic plate and a magnet, the magnetic plate is arranged on a partition near the front end of the mixing channel, the hydraulic cylinder is arranged above the magnetic plate, the magnet is connected to the push rod of the hydraulic cylinder, and the hydraulic cylinder drives the magnet to adhere to the magnetic plate and pull the partition upward.

[0016] By adopting the above technical solution, the push rod of the hydraulic cylinder extends, driving the magnet to move downward. When the magnet is attracted to the magnetic plate, the push rod of the hydraulic cylinder is retracted, driving the magnet and the magnetic plate to move upward at the same time. Since the magnetic plate is connected to the partition close to the mixing channel, the magnetic plate will drive the partition to move upward, while the partition close to the flue gas channel is in a fixed connection state. In this way, the condenser will tilt. During this process, horizontal slip and dislocation will occur between the magnetic plate and the magnet. When the condenser is tilted to a certain angle, the magnetic plate will separate from the magnet, and the magnetic plate, partition and condenser will rotate downward and reset under the action of gravity. In this way, the relative position between the condenser and the external cold air will change through repeated attraction and separation of the magnet and the magnetic plate, thereby improving the cooling effect of the external cold air on the condenser, and after the free fall of the condenser is completed, it will form an oscillation effect on itself, which can promote the flow of condensed water on the condenser.

[0017] Optionally, the partition close to the mixing channel is movably inserted in the shell, and the partition close to the smoke channel is fixed in the shell.

[0018] This technical solution ensures that once the magnets engage the magnetic plate, the hydraulic cylinder's push rod drives the partitions near the mixing channel to reposition, thereby changing the relative position between the condenser and the external cold air. The partitions near the flue gas channel remain fixed, ensuring that all flue gas flows through the channel into the condenser.

[0019] Optionally, the end of the condenser pipe is connected to a partition close to the flue gas channel via a hose, one end of the hose passes through the partition and is connected to the flue gas channel, and the other end of the hose is connected to the condenser pipe.

[0020] By adopting the above technical solution, the swing angle of the condenser can be increased without causing the condenser to bend or break, thereby maximizing the uniformity of cooling the condenser by external cold air, and also improving the oscillation effect produced by the condenser after free falling and resetting.

[0021] Optionally, the adjustment mechanism includes a rack and a gear meshing with each other, the gear being driven by a motor, a pair of partitions having opposite sides each provided with an end-to-end receiving groove, a bottom of the receiving groove being provided with a plurality of air holes, the rack being arranged in the receiving groove, the rack being provided with a plurality of insertion holes, the condenser being inserted into the insertion holes;

[0022] The thickness of the rack is greater than the depth of the accommodating groove. A motor is arranged in the shell, and a gear meshing with the rack is arranged on the output shaft of the motor.

[0023] By adopting the above technical solution, driven by the motor, the gear rotates and drives the rack to move within the receiving tank. Since the rack is also connected end to end within the receiving tank, the rack will slide in a circular motion along the opening direction of the receiving tank. The two ends of the condenser are respectively inserted into the insertion holes of a pair of racks. When the rack slides in a circular motion within the receiving tank, the condenser will also move with the rack. Since the bottom of the receiving tank is provided with an air hole, when the condenser and the air hole are in a connected state, the flue gas can enter the condenser through the air hole and then pass from the condenser to the mixing channel through the air hole, ensuring that the condenser does not affect the flow of flue gas during its movement. When several condenser tubes slide along the trajectory of the receiving tank, the relative position between the condenser tube and the external cold air changes, that is, any condenser tube can rotate from a position away from the external cold air to a position close to the external cold air, thus effectively improving the cooling effect of the external cold air on the condenser tube.

[0024] Optionally, the accommodating groove includes a straight portion and at least two curved portions, the curved portion is S-shaped, and multiple curved portions are connected in sequence, one end of the straight portion is connected to the front end of the frontmost curved portion, and the other end of the straight portion is connected to the rear end of the rearmost curved portion; the gear is engaged with the straight portion.

[0025] By adopting the above technical solution, the setting of multiple curved parts can increase the number of condenser tubes, and then the curved parts are connected by straight parts to ensure that the rack can be in a closed loop, which facilitates the driving of the condenser tube through the engagement of the gear and the rack.

[0026] Optionally, a pair of partitions are fixed in the shell, and the motor and the driving gear are respectively located on both sides of the same partition.

[0027] By adopting this technical solution, the partition provides excellent support for the condenser and rack. Furthermore, by properly adjusting the length of the condenser, the condenser can adjust the pressure of the rack on the rack within the trough, thereby ensuring that the rack will not disengage from the trough during the condenser's rotation. The driving gear and the condenser are located on the same side, and the motor is positioned away from the condenser, preventing interference with the condenser during rotation.

[0028] Optionally, a condensed water outlet is further provided in the shell, and the condensed water outlet is located at the end of the mixing channel.

[0029] By adopting the above technical solution, after the flue gas enters the interior of the condenser, it will contact the inner wall of the condenser to produce condensed water. After passing through the condenser, the flue gas will enter the mixing channel and blow through the outer wall of the condenser with the external cold air, thereby producing condensed water on the outer wall of the condenser. The condensed water from the two places will converge at the end of the mixing channel and be discharged outward through the condensed water outlet.

[0030] In summary, this application has the following beneficial effects:

[0031] 1. Through the operation of the fan, an air flow channel with negative pressure is formed in the smoke channel and the mixing channel, and the cold air inlet is arranged above the door of the steam-bake oven, so that the smoke in the steam-bake oven is sucked into the mixing channel through the smoke channel, and the smoke overflowing when the door of the steam-bake oven is opened is sucked into the mixing channel through the cold air inlet and discharged through emptying. This can prevent the smoke overflowing from the steam-bake oven from rushing towards the user's face when the door of the steam-bake oven is opened, ensuring that the user can accurately observe the interior of the steam-bake oven.

[0032] 2. By setting up several condensing pipes at the end of the flue gas channel, the flue gas in the steam oven can be introduced into the shell in real time, and the flue gas can be condensed in the process of passing through the condensing pipe. The flue gas is then discharged into the cold air inlet through the condensing pipe, and blows through the surface of the condensing pipe together with the external cold air to achieve the cooling effect on the condensing pipe, and finally discharged from the exhaust port, which can effectively condense and purify the flue gas and avoid direct emission to cause environmental pollution.

[0033] 3. By setting an adjustment mechanism in the shell, the contact position between several condensing tubes and external cold air can be changed, thereby improving the uniformity of the cooling effect of the external cold air on the condensing tubes. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is combined with Figure 1-6 This application is described in further detail.

[0042] Example 1

[0043] Figure 1 is a schematic three-dimensional diagram of Example 1 in this application, Figure 2 This is a schematic diagram of the internal structure of Example 1 in this application. Figure 1 See also Figure 1 and Figure 2 This embodiment discloses a smoke condensation hood for a steam-bake oven, comprising a shell 1. The bottom of the shell 1 is provided with a smoke inlet 11 connected to the steam-bake oven, the top is provided with an exhaust port 12, and a cold air inlet 13 is provided on the outer wall on one side above the door of the steam-bake oven. The interior of the shell 1 is provided with a smoke channel 2 and a mixing channel 3.

[0044] A fan 5 is provided in the mixing channel 3, with the air inlet end of the fan 5 facing the cold air inlet 13 and the air outlet end facing the exhaust port 12. When the fan 5 is in operation, a negative pressure is generated in the mixing channel 3. Since the end of the smoke channel 2 is connected with the front end of the mixing channel 3, the smoke in the steam-bake oven will enter the smoke channel 2 of the shell 1 through the smoke inlet 11. When the door of the steam-bake oven is opened, the operating power of the fan 5 will increase rapidly at the same time. In this way, the smoke overflowing when the door of the steam-bake oven is opened will be sucked into the mixing channel 3 through the cold air inlet 13, effectively preventing the overflowing smoke from rushing to the user's face. Moreover, after the external cold air enters the mixing channel 3 through the cold air inlet 13, the external cold air with a lower temperature can form a condensation effect on the smoke in the steam-bake oven gathered in the mixing channel 3 and the smoke overflowing when the door of the steam-bake oven is opened, thereby achieving a purification effect on the mixed smoke.

[0045] See also Figure 2 A pair of partitions 6 are provided in the shell 1. The partitions 6 are used to install the condensing pipes 4. The pair of partitions 6 are respectively located at both ends of the condensing pipes 4. Several condensing pipes 4 are arranged in the mixing channel 3. A condensed water outlet 14 is provided at the end of the mixing channel 3. One end of the condensing pipe 4 passes through a partition 6 and is connected to the flue gas channel 2. The other end of the condensing pipe 4 passes through another partition 6 and is connected to the front end of the mixing channel 3. At the same time, the partition 6 is also used to separate the flue gas channel 2 and the mixing channel 3, so that the flue gas can completely enter the condensing pipe 4 from the flue gas channel 2, and then completely enter the mixing channel 3 from the condensing pipe 4, without causing the flue gas to float around in the shell 1.

[0046] After the smoke generated by the steam oven enters the smoke channel 2 of the shell 1 through the smoke inlet 11, it will contact the inner wall of the smoke channel 2, thereby producing a condensation effect, thereby purifying the smoke. Then the smoke in the smoke channel 2 will all enter several condensing tubes 4 and contact the inner walls of the condensing tubes 4, and condense again, thereby improving the purification effect of the smoke. Then the smoke is discharged from the condensing tubes 4 and enters the mixing channel 3. The condensed water generated by the contact between the smoke and the smoke channel 2 and the condensing tubes 4 will flow in the shell 1 and be discharged to the outside of the shell 1 through the condensed water outlet 14.

[0047] An adjustment mechanism is also provided in the shell 1, which is used to adjust the relative positions between several condensing tubes 4 and external cold air, thereby improving the cooling effect of the external cold air on the condensing tubes 4, and then ensuring that the flue gas in the flue gas channel 2 can be reliably condensed after entering the condensing tubes 4, thereby achieving the purification of the flue gas.

[0048] Figure 3 This is a schematic diagram of the internal structure of Example 1 in this application. Figure 2 See also Figure 3 Combined with Figure 2The regulating mechanism includes a hydraulic cylinder 71, a magnetic plate 72 and a magnet 73. The magnetic plate 72 is arranged on the partition 6 near the front end of the mixing channel 3, and the partition 6 is in a movable setting state, and the other partition 6 is in a fixed setting state. The condenser 4 is passed through the partition 6 and is connected to the other partition 6 through a hose 74. One end of the hose 74 passes through the partition 6 and is connected to the flue gas channel 2. The other end of the hose 74 is connected to the condenser 4. The hydraulic cylinder 71 is arranged above the magnetic plate 72. The push rod of the hydraulic cylinder 71 is connected to the magnet 73 and pushes the magnet 73 downward. When the magnet 73 is attracted to the magnetic plate 72, the push rod of the hydraulic cylinder 71 retracts, which will drive the magnetic plate 72 and the movable partition 6 move upward. Since the other partition 6 is in a fixed state and the condenser 4 is connected to the other partition 6 through a hose 74, when one partition 6 moves upward under the drive of the magnet 73 and the magnetic plate 72, the condenser 4 will rotate around the hose 74. In this way, the relative position between the external cold air and the condenser 4 will change. That is to say, when the position of the condenser 4 changes, the external cold air will cool down different positions of the same condenser 4, effectively improving the uniformity of the cooling effect of the external cold air on the condenser 4, thereby improving the condensation and purification effect of the flue gas in the condenser 4.

[0049] Driven by the hydraulic cylinder 71, several condenser tubes 4 rotate around the corresponding hose 74. In this way, during the rising process of the movable partition 6, horizontal slip will occur between the magnet 73 and the magnetic plate 72. When the condenser tube 4 rotates to a certain angle, the magnet 73 and the magnetic plate 72 are separated from each other, the magnetic attraction is released, and the partition 6 will fall freely to its original position. When the movable partition 6 contacts the shell 1 again, it will collide with the shell 1, thereby forming an oscillation effect on the partition 6 and several condenser tubes 4, thereby promoting the condensed water adhering to the inner and outer walls of the condenser tube 4 to flow into the mixing channel 3 and be discharged outward through the condensed water outlet 14. In this way, the cooling effect of the external cold air on the condenser tube 4 can be ensured to be reliable, which also ensures that the flue gas can be reliably condensed and purified after passing through the condenser tube 4.

[0050] Example 2

[0051] Figure 4 This is a schematic diagram of the internal structure of Example 2 in this application Figure 1 , Figure 5 This is an exploded view of the condenser, rack and partition in Example 2 of this application. Figure 4 and Figure 5The difference between this embodiment and the first embodiment is that the adjustment mechanism includes a rack 81 and a gear 82 that mesh with each other, the gear 82 is driven by a motor 83, the partition 6 is fixed in the shell 1, and a ring-shaped receiving groove 61 is provided on the partition 6. The notches of the two receiving grooves 61 on a pair of partitions 6 are arranged opposite to each other, and a rack 81 is provided in the receiving groove 61. The rack 81 extends along the trajectory of the receiving groove 61 and is connected end to end. The thickness of the rack 81 is greater than the depth of the receiving groove 61. The part of the rack 81 located outside the receiving groove 61 is meshed with the gear 82. The motor 83 and the gear 82 are respectively located on both sides of the partition 6. The rack 81 is provided with a socket 810 for inserting the condenser tube 4, and the bottom of the receiving groove 61 is provided with an air hole 62.

[0052] Figure 6 This is a schematic diagram of the internal structure of Example 2 in this application Figure 2 See also Figure 6 and combined Figure 5 The flue gas enters the condenser 4 from the flue gas channel 2 through the air holes 62 on one partition 6, and then enters the mixing channel 3 from the condenser 4 through the air holes 62 on another partition 6. After the condenser 4 is inserted into the socket 810, there is a distance between the end of the condenser 4 and the bottom of the accommodating groove 61. In this way, the speed at which the flue gas penetrates into the mixing channel 3 through the several air holes 62 can be maximized. When the motor 83 drives the driving wheel to rotate, the driving wheel will drive the rack 81 to move. Since the rack 81 is also connected end to end in the accommodating groove 61, and the rack 81 is reliably limited inside the accommodating groove 61 (that is, by reasonably setting the length of the condenser 4, the rack 81 can be provided with horizontal support force to prevent the rack 81 from falling off from the accommodating groove 61 when rotating), the rack 81 can rotate smoothly in the accommodating groove 61, and through the rotation of the rack 81, the multiple condenser tubes 4 can be driven to rotate on the trajectory defined by the accommodating groove 61, so that any condenser tube 4 can be rotated to a position close to and directly facing the external cold air, thereby improving the cooling effect of the external cold air on the condenser tube 4. In this way, when the multiple condenser tubes 4 continuously and successively rotate to a position close to the external cold air, the air cooling effect of the external cold air on the condenser tube 4 is significantly improved, ensuring that the flue gas can be condensed and purified in the condenser tube 4.

[0053] See also Figure 5The accommodating groove 61 includes a straight portion and two curved portions, the curved portions are S-shaped, and the multiple curved portions are connected in sequence. One end of the straight portion is connected to the front end of the curved portion on the front side, and the other end of the straight portion is connected to the rear end of the curved portion on the rear side. The gear 82 is meshed with the straight portion. Through such an arrangement, more condensing tubes 4 can be assembled in a limited space, thereby improving the condensation effect on the flue gas. When the number of curved portions is large, the rack 81 will undergo a large deformation to ensure that the rack 81 can slide adaptively in the accommodating groove 61. Rubber material can be selected to make the rack 81, and the teeth of the rack 81 are cured. In this way, the rack 81 can be deformed along the trajectory of the curved portion and return to its original shape in the straight portion. The cured teeth can reliably mesh with the driving wheel, ensuring that the driving wheel can drive the rack 81 to rotate in the accommodating groove 61, thereby achieving a change in the position of the condensing tube 4 and improving the air cooling effect of the external cold air on the condensing tube 4.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
