Description

Technical Field

[0001] The invention relates to the field of cooking devices, and in particular to an integrated stove with a cooking device and a method for drying an inner pot thereof. Background Art

[0002] The working principle of cooking devices with steaming function, such as steam ovens, steam-bake combination machines and microwave steam-bake combination machines, is mainly to heat and steam food by filling the inner pot with steam. Some steam cooking devices use external steam generators to supply steam, while others use built-in steam generators to supply steam.

[0003] After cooking, some steam will remain in the inner pot. In this way, not only when the door is opened, the steam in the inner pot will rush directly to the user, thus causing a bad user experience, but also after the steam condenses, the condensed water will accumulate in the inner pot. If it is not used for a long time, it will not only cause the relevant parts to be corroded, affecting the service life, but also breed a large number of bacteria, thus causing safety hazards. At present, there is a way to solve the above problem by extracting steam from the inner pot. For example, the Chinese invention patent with application number CN201810025623.2 (publication number CN110025227A) discloses an oven with automatic dehumidification and drying function, which includes a cooking chamber, characterized in that it also includes: a dehumidification device, arranged on the outer wall of the cooking chamber, the dehumidification device includes a rotating member and a driving structure for driving the rotating member to rotate; a through hole, which is opened on the outer wall of the cooking chamber to accommodate the rotating member; and the rotating member exposes its partial surface to the inside or outside of the cooking chamber in rotation during the rotation of the through hole; a water storage box, which is arranged below the rotating member. This patent realizes drying of the condensed water in the cooking chamber by pumping the condensed water out of the cooking chamber. However, this method requires condensing the steam first and then pumping it out of the cooking chamber, and the drying efficiency is poor. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide an integrated stove with a cooking device with high inner tank drying efficiency in view of the prior art.

[0005] The second technical problem to be solved by the present invention is to provide an integrated stove with a cooking device having good heat dissipation effect in view of the prior art.

[0006] The third technical problem to be solved by the present invention is to provide a method for drying the inner pot of the above-mentioned integrated stove with high inner pot drying efficiency in view of the prior art.

[0007] The technical solution adopted to solve the first and second technical problems mentioned above is: an integrated stove with a cooking device, comprising a cooking device with an inner pot and a stove with a burner, the stove is arranged above the above cooking device, and the stove comprises a stove shell, characterized in that a ventilation hole is opened on one side wall of the stove shell, an air outlet is opened on the other side wall, and an air inlet and an exhaust port are respectively opened on the side walls of the above inner pot, and the air inlet is fluidically connected with the above air outlet.

[0008] In order to allow the hot air in the inner cavity of the stove shell to enter the inner pot more efficiently, thereby improving the drying efficiency of the inner pot, the integrated stove in the present invention also includes an air supply device for guiding the airflow from the air outlet of the stove shell to the air inlet of the inner pot, and the air inlet port of the air supply device is fluidically connected to the air outlet of the above-mentioned stove shell.

[0009] Preferably, the air outlet of the range shell is connected to the air inlet of the inner pot through an air supply pipe, and the air supply device is arranged on the air supply pipe.

[0010] Preferably, the air supply pipe is also provided with a control valve for controlling the opening and closing of the air supply pipe, so that the input of air from the inner cavity of the stove shell to the inner pot can be better controlled through the control valve, thereby achieving drying of the inner pot.

[0011] Preferably, the air inlet is opened at the lower part of the inner pot, so that the hot air in the stove shell is transported to the lower part of the inner pot, and the inner pot can be better heated by the principle of hot air rising upward, so that the condensed water on the inner surface of the inner pot can be better heated and volatilized.

[0012] Preferably, the air delivery device is an air pump.

[0013] Preferably, the burner is located between the vent and the air outlet of the stove shell, so that the heat transferred to the air in the stove shell by the burner can be better taken out by the air outlet, which can not only increase the heat of the air input into the air duct, but also further solve the impact of the burner combustion on the internal components of the stove.

[0014] Furthermore, preferably, an air delivery channel is provided in the inner cavity of the stove shell, the lower end of the burner is embedded in the air delivery channel, and one end of the air delivery channel is in fluid communication with the vent, and the other end is in fluid communication with the air outlet. By providing the air delivery channel, the heat of the air transferred from the burner to the inner cavity of the stove shell can be taken away from the air outlet to the greatest extent, and the influence of the heat generated by the burner on the internal components of the stove can be avoided to the greatest extent, thereby greatly improving the internal heat dissipation of the stove, thereby improving the performance of the stove and extending its service life.

[0015] Preferably, the stove shell comprises a bottom plate with an upper opening and a panel covering the bottom plate opening, the two forming an inner cavity of the stove shell, and the ventilation opening and the air outlet are respectively provided on the left and right side walls of the bottom plate.

The hot air blower heats the air flow inside the inner pot, thereby further avoiding steam condensation and promoting the volatilization of condensed water on the inner surface of the inner pot, and negative pressure is formed in the hot air chamber due to the rotation of the hot air blower, so that the hot air in the inner pot can be better guided into the hot air chamber and discharged through the exhaust port, and at the same time, due to the negative pressure attraction of the hot air chamber, the hot air in the air duct can be driven into the inner pot, thereby improving the efficiency of the hot air in the stove shell entering the inner pot, and improving the drying efficiency of the inner pot.

[0017] The steam used for heating in the cooking device can be generated in a variety of ways. At present, an external steam generator is generally used.

[0030] The present invention is further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 6 As shown, an integrated stove with a cooking device includes a cooking device 102 with a steaming function and a stove 101 arranged above the cooking device 102, the cooking device 102 includes an inner pot 1, and the stove 101 includes a stove shell 100, the stove shell 100 includes a bottom plate 1002 with an upper opening and a panel 1001 covering the opening of the bottom plate 1002, and the inner cavity of the stove shell 100 is formed between the two.

[0032] In this embodiment, a vent 1002a is provided on the left side wall of the chassis 1002, and an air outlet 1002b is provided on the right side wall, and the vent 1002a is arranged opposite to the air outlet 1002b. An air inlet 12 and an air outlet 11 are respectively provided on the side walls of the inner liner 1. In this embodiment, the air inlet 12 is provided at the lower part of the right side wall of the inner liner 1, and the air outlet 11 is provided on the back plate of the inner liner 1. The air inlet 12 is fluidly connected with the air outlet 1002b: when the air inlet 12 and the air outlet 1002b are arranged adjacent to each other, the two can be connected to each other (not shown); when the air inlet 12 and the air outlet 1002b are far apart, the two can be connected through a pipeline. In this embodiment, the air inlet 12 and the air outlet 1002b are connected through the air supply pipe 80 described below. The burner 1004 of the stove 101 generates heat when burning, which causes the air temperature in the inner cavity of the stove shell 100 to rise. In the present invention, the high-temperature air in the stove shell 100 is introduced into the inner pot 1. The hot air can heat and volatilize the condensed water on the inner surface of the inner pot 1, and the heated hot air is discharged through the exhaust port 11. This not only achieves rapid drying of the inner pot 1, but also because the high-temperature gas in the stove shell 100 is discharged to the inner pot 1, it can effectively achieve heat dissipation inside the stove shell 100, thereby preventing the internal temperature of the stove shell 100 from being too high and affecting the normal functions of components such as the power board. Since the integrated stove is generally embedded in a cabinet, part of the heat emitted outward by the integrated stove when it is working is accumulated between the integrated stove and the cabinet. Therefore, even if the burner 1004 in the stove 101 is not working, the air input through the air inlet 12 also has a certain temperature. Therefore, after the warm air with a certain temperature enters the inner cavity of the stove shell 100 through the air inlet 12, it is input into the inner pot 1 through the air delivery pipe 80, which can also have a certain heating and drying effect on the inner pot 1. It can be seen that in the present invention, the inner pot 1 can be dried when the burner 1004 is working or not working.

[0033] In order to allow the hot air in the inner cavity of the stove shell 100 to enter the inner pot 1 more efficiently, thereby improving the drying efficiency of the inner pot 1, the integrated stove in the present invention also includes an air delivery device 8 for guiding the airflow from the air outlet 1002b of the stove shell 100 to the air inlet 12 of the inner pot 1, and the air inlet port of the air delivery device 8 is fluidly connected with the air outlet 1002b of the stove shell 100. The air outlet 1002b of the stove shell 100 is connected with the air inlet 12 of the inner pot 1 through the air delivery pipe 80, and the air delivery device 8 is arranged on the air delivery pipe 80. That is, in this embodiment, the air inlet port of the air delivery device 8 is connected with the air outlet 1002b of the stove shell 100 through the air delivery pipe 80. The air delivery device 8 can be implemented in a variety of ways. Preferably, in this embodiment, the air delivery device 8 is an air pump. In addition, the air supply pipe 80 is also provided with a control valve 81 for controlling the opening and closing of the air supply pipe 80 , so that the control valve 81 can better control the input of air from the inner cavity of the stove shell 100 into the inner pot 1 , thereby achieving drying of the inner pot 1 .

[0034] In the present embodiment, since the air inlet 12 is provided on the left side wall of the stove shell 100, and the air outlet 1002b is provided on the right side wall of the stove shell 100, the burner 1004 of the stove 101 is located between the vent 1002a and the air outlet 1002b. In this way, the heat transferred from the burner 1004 to the air in the inner cavity of the stove shell 100 can be better brought out through the air outlet 1002b, which can not only increase the heat of the air input into the air duct 80, but also further solve the influence of the combustion of the burner 1004 on the internal components of the stove 101. Further, preferably, an air delivery channel 83 is provided in the inner cavity of the stove shell 100, and the lower end of the burner 1004 is embedded in the air delivery channel 83, and one end of the air delivery channel 83 is in fluid communication with the vent 1002a, and the other end is in fluid communication with the air outlet 1002b. In this embodiment, the two ends of the air delivery channel 83 are directly connected to the vent 1002a and the air outlet 1002b respectively. By providing the air delivery channel 83, the heat of the air in the inner cavity of the stove shell 100 transferred by the burner 1004 can be taken away from the air outlet 1002b to the greatest extent, and the heat generated by the burner 1004 can be avoided to the greatest extent. The influence of the internal components of the stove 101 on the heat generated by the burner 1004 is avoided, thereby greatly improving the internal heat dissipation of the stove 101, thereby improving the performance of the stove 101 and extending its service life.

[0035] Preferably, the inner pot 1 is provided with a hot air baffle 31 with an air inlet and an air outlet, and a hot air chamber 30 is formed between the hot air baffle 31 and the back plate of the inner pot 1. The hot air chamber 30 is provided with a hot air blower 3, and a circular back heating pipe 32 is provided around the outer periphery of the hot air blower 3. The exhaust port 11 is connected with the hot air chamber 30 and is opened on the back plate of the inner pot 1. The hot air blower 3 heats the air flow inside the inner pot 1, thereby further avoiding steam condensation and promoting the volatilization of condensed water on the inner surface of the inner pot 1. The hot air blower 3 rotates to form a negative pressure in the hot air chamber 30, thereby better guiding the hot air of the inner pot 1 to enter the hot air chamber 30 and be discharged through the exhaust port 11. At the same time, due to the negative pressure attraction of the hot air chamber 30, the hot air in the air supply pipe 80 can be driven to enter the inner pot 1, thereby improving the efficiency of the hot air in the stove shell 100 entering the inner pot 1, and improving the drying efficiency of the inner pot 1.

[0036] In addition, the steam used for heating in the cooking device 102 can be generated in a variety of ways, and currently an external steam generator is generally used. In this embodiment, a heating plate 4 is provided at the bottom of the inner pot 1, and a water inlet (not shown) is provided on the inner pot 1. The water inlet is connected to a water inlet pipe 64 connected to a water inlet pump 61, and a solenoid valve 62 for opening and closing the water inlet pipe 64 is provided on the water inlet pipe 64. The water inlet pipe 64 is connected to the water outlet of the water tank 63, and the water in the water tank 63 enters the water inlet pipe 64, and the water in the water inlet pipe 64 enters the inner pot 11 through the water inlet. The heating plate 4 heats the water in the inner pot 1 to generate steam, and the generated steam is used to heat the food. At the same time, after the steaming process is completed, the condensed water remaining on the inner bottom surface of the inner pot 1 can be effectively evaporated by heating the bottom of the inner pot 1 through the heating plate 4.

[0037] The method for drying the inner tank of the integrated stove in the present invention comprises the following steps:

[0038] S1: 8 minutes before the steaming process is completed, the water inlet pump 61 and the electromagnetic valve 62 are turned off, the inner pot 1 stops inletting water, and the heating plate 4 continues to work. The inner pot 1 is heated by the heating plate 4, which can prevent the steam in the inner pot 1 from condensing to a certain extent.

[0039] S2: Open the air delivery device 8 and the control valve 81 respectively, and the hot air in the stove shell 100 enters the inner pot 1 through the air outlet and the air inlet 12. Thus, the high-temperature air in the stove shell 100 is introduced into the inner pot 1, and the hot air can heat and volatilize the condensed water on the inner surface of the inner pot 1.

[0040] S3: Turn on the hot air blower 3 and the back heating pipe 32, and the airflow in the inner pot 1 enters the hot air chamber 30 and is discharged through the exhaust port 11. The hot air blower 3 heats the airflow inside the inner pot 1 to further prevent steam condensation, and the negative pressure formed in the hot air chamber 30 drives the airflow in the inner pot 1 to be discharged through the exhaust port 11.
