[0046] Embodiment 1

[0047] In view of the fact that in the prior art, the condensed water treatment effect at the bottom of the inner pot of an electric steamer or a steam oven is poor, and the problem of odor transfer will occur when cooking food, this embodiment provides a condensed water recovery device to solve the above technical problem, and the condensed water recovery device is used to recover the condensed water in the steamer.

[0048] Specifically, Figures 1 to 4 As shown, the condensed water recovery device provided in this embodiment includes a base 1 and a residual water storage box 3. The base 1 is arranged at the bottom of the steam box 100. The base 1 is provided with a collection tank 2, which is connected to the inner tank 101 of the steam box 100. The residual water storage box 3 is connected to the collection tank 2, and the residual water storage box 2 is connected to the bellows 201 of the range hood 200 through a recovery pipe. The recovery pipe is provided with a water pump 4 for pumping water in the residual water storage box 2 to the bellows 201.

[0049] The condensed water recovery device provided in this embodiment discharges the condensed water at the bottom of the inner tank 101 of the steamer 100 into the collecting tank 2, and the condensed water in the collecting tank 2 is collected in the residual water storage box 3, thereby realizing the effective discharge of the condensed water in the inner tank 101, and there will be no problem of odor when the steamer is cooking food; the water level detection component is used to detect the water level in the residual water storage box 3, and when the water level reaches the preset water level, the water pump 4 can pump the water in the residual water storage box 3 into the bellows 201 of the range hood 200 for cleaning the impeller, thereby realizing the recycling of condensed water, saving energy, and improving user satisfaction.

[0050] Optionally, a condensate recovery port 5 is provided at the bottom of the inner pot 101 of the steamer 100, and the collecting tank 2 is connected to the inner pot 101 through the condensate recovery port 5. The condensate in the inner pot 101 is collected at the bottom of the inner pot 101 and flows into the collecting tank 2 through the condensate recovery port 5.

[0051] The collecting tank 2 is formed on the bottom bracket 1. The bottom bracket 1 is a sheet metal part. The collecting tank 2 can be directly punched on the bottom bracket 1, which is easy to process. A connecting hole 6 is opened at the bottom of the collecting tank 2.

[0057] Embodiment 2

[0058] like Figure 5 As shown, this embodiment provides a method for cleaning a range hood impeller, which is applied to the condensed water recovery device provided in the first embodiment. The method for cleaning a range hood impeller includes:

[0059] Controlling the steam box 100 to work and determining that the water in the residual water storage box 3 reaches a preset water level;

[0060] Control the range hood 200 to start;

[0061] The water pump 4 is controlled to draw water from the residual water storage box 3 into the wind box 201 of the range hood 200 and spray it toward the impeller.

[0062] After the water in the residual water storage box 3 reaches the preset water level, the water in the residual water storage box 3 is pumped into the bellows 201 of the range hood 200 for cleaning the impeller, thereby realizing the recycling of the condensed water formed in the steamer 100 and the cleaning of the impeller, saving energy and improving user satisfaction.

[0063] like Figure 6 The following is a detailed flow chart of the method for cleaning the range hood impeller provided in this embodiment. Figure 6 The method for cleaning the range hood impeller provided in this embodiment is introduced in detail.

[0064] The method for cleaning the range hood impeller includes the following steps:

[0065] Step 1: Control the steam box 100 to work.

[0066] Specifically, when the steamer 100 is started to cook food, the steam generator works, and water vapor is generated in the inner pot 101 of the steamer 100. The water vapor adheres to the side wall of the inner pot 101 to form condensed water, and the condensed water flows to the bottom of the inner pot 101 by its own gravity, and is discharged into the collection tank 2 and stored in the residual water storage box 3, which improves the effect of condensed water treatment in the steamer 100, avoids the problem of excessive treatment of condensed water or incomplete treatment, and can also avoid the problem of cross-flavor when cooking food.

[0067] The working principle of the steam box 100 is known in the art and will not be described in detail here.

[0068] Step 2: determine whether the water level in the residual water storage box 3 reaches a preset water level.

[0069] Specifically, during the cooking process of the steam box 100, condensed water generated in the inner pot 101 of the steam box 100 is collected in the residual water storage box 3. As the amount of water in the residual water storage box 3 increases, the water in the residual water storage box 3 needs to be discharged in time to prevent the water in the residual water storage box 3 from overflowing. Therefore, a water level detection member is provided in the residual water storage box 3, and the water level detection member is used to detect the water level in the residual water storage box 3.

[0070] The water level detection member detects the water level in the residual water storage box 3, and starts draining when the water level in the residual water storage box 3 reaches a preset water level. The preset water level is the upper limit water level of the residual water storage box 3, which can be the water level when the residual water storage box 3 is full of water, and is not specifically limited here.

[0071] Step 3: If yes, control the range hood 200 to start and run at a low speed.

[0072] Specifically, when the water level in the residual water storage box 3 reaches a preset water level, the range hood 200 is started and operates at a low speed gear. When the water in the residual water storage box 3 is pumped into the bellows 201, it is ensured that the water can fully flush the impeller with low noise.

[0073] Step 4: Control the water pump 4 to pump water, and measure the number of times the water pump 4 pumps water.

[0074] Specifically, after the range hood 200 is started, the water pump 4 pumps water to discharge the water in the residual water storage box 3 into the bellows 201 of the range hood 200. Whether the range hood 200 is running at a high speed is determined according to the number of times the water pump 4 pumps water. Running the range hood 200 at a high speed can shake off the oil and water stains on the impeller, thereby improving the cleaning effect of the impeller.

[0075] The amount of water pumped by the water pump 4 each time is fixed. When the number of times the water pump 4 pumps water reaches a preset value, it can ensure that the impeller is fully flushed and cleaned. Then the range hood 200 can be controlled to run at a high speed to shake off the oil and water stains on the impeller, thereby improving the cleaning effect of the impeller.

[0076] The measurement of the number of times the water pump 4 pumps water can be obtained by controlling the number of times the water pump 4 is started by a metering controller, or by other methods, which are not specifically limited here.

[0077] Step 5: determine whether the number of times the water pump 4 pumps water is less than or equal to a first preset value. If so, the range hood 200 runs at a low speed gear.

[0078] Specifically, during the process of the water pump 4 pumping water, if the number of times the water pump 4 pumps water is less than or equal to the first preset value, it means that the amount of water used to flush the impeller is insufficient and the impeller cannot be flushed and cleaned, so the range hood 200 runs at a low speed.

[0079] The value of the first preset value can be set according to the amount of water pumped by the water pump 4 each time and the size of the impeller. A large-sized impeller requires more water during cleaning.

[0080] Step 6: If the number of times the water pump 4 pumps water is greater than the first preset value and the number of times the water pump 4 pumps water is less than the second preset value, control the range hood 200 to switch from the low speed gear to the high speed gear and run at the high speed gear for a preset time.

[0081] Specifically, when it is detected that the number of times the water pump 4 pumps water is greater than a first preset value, the range hood 200 is controlled to switch from a low speed gear to a high speed gear, and the impeller of the range hood 200 rotates at a high speed to shake off oil and water stains on the impeller.

[0082] When the number of times the water pump 4 pumps water is less than the second preset value, the range hood 200 runs at a high speed gear, and is controlled to run at a high speed gear for a preset time to achieve sufficient flushing and cleaning of the impeller of the range hood 200.

[0083] Step seven, controlling the range hood 200 to stop working.

[0084] After the range hood 200 runs at the high speed gear for a preset time, the range hood 200 is controlled to stop working, thereby completing the cleaning of the impeller of the range hood 200.

[0085] Step 8: When the number of times the water pump 4 pumps water is greater than or equal to the second preset value, the steam box 100 and the water pump 4 are controlled to stop working, and a prompt is given that the oil cup 300 is full.

[0086] Specifically, after the range hood 200 stops working, if the steam box 100 is still cooking food, condensed water will continue to be generated in the inner pot 101 of the steam box 100, so the water pump 4 needs to continue pumping water to ensure that the condensed water in the inner pot 101 of the steam box 100 can be fully discharged. If the number of times the water pump 4 pumps water is greater than or equal to the second preset value, the steam box 100 and the water pump 4 are controlled to stop working, and a prompt is given that the oil cup 300 is full.

[0087] If the steamer 100 finishes cooking food after the range hood 200 stops working, the water pump 4 can stop working; or the water pump 4 can pump out all the water in the residual water storage box 3 to ensure the cleanliness of the residual water storage box 3. In this case, if the number of times the water pump 4 pumps water is greater than or equal to the second preset value, the water pump 4 is controlled to stop working and a prompt is given that the oil cup 300 is full.

[0088] The node for starting the water pump 4 to pump water each time involved in the above steps can be that after the water in the residual water storage box 3 reaches a preset water level, the water pump 4 starts to pump a fixed amount of water, and then stops pumping water, and then waits until the water in the residual water storage box 3 reaches the preset water level, and then starts the water pump 4 to pump water again, and repeats this cycle.

[0089] The fixed amount of water pumped by the water pump 4 each time may be less than the amount of water contained in the residual water storage box 3, or may be equal to the amount of water contained in the residual water storage box 3, which is not specifically limited here.

[0090] Whether the oil cup 300 is full is determined according to the number of times the water pump 4 is used, the amount of water pumped by the water pump 4 each time, and the volume of the oil cup 300. If the oil cup 300 is full, the user is prompted to clean the oil cup 300 in time.

[0091] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
