[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0034] The terms "a", "an", "the", "" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0035] A water supply system according to an embodiment of the utility model comprises a water supply component 1, a water quantity detection component 2 and a controller, the water supply component 1 comprises a first water inlet branch 10 and a second water inlet branch 11, the water outlet end of the first water inlet branch 10 and the water outlet end of the second water inlet branch 11 are respectively connected to a steam generator 100, the water receiving end of the first water inlet branch 10 is connected to a water box 12, and the water inlet end of the second water inlet branch 11 is connected to a direct drinking water machine 13; the water quantity detection component 2 is connected between the water supply component 1 and the steam generator 100, and is used to detect the water supply amount of the water supply component 1; the controller is connected to the water quantity detection component 2 and the water supply component 1, wherein the controller controls the water supply amount of the water supply component 1 to the steam generator 100 according to the water quantity detection component 2. Specifically, the water volume detection component 2 can be a flow meter 21, and the first water inlet branch 10 and the second water inlet branch 11 are respectively connected to the water inlet end of the water volume detection component 2 through the three-way joint 14, so that the water volume detection component 2 can detect the water supply of the water supply component 1, and the controller can calculate the required water volume of the steam generator 100 according to the cooking period and the cooking temperature. The water volume detection component 2 can be used to detect the water supply to the steam generator 100 in real time. If the water volume detection component 2 cannot detect the water flow, it means that there is no water in the water box 12 and the direct drinking water machine 13. At this time, the controller can sound an alarm and prompt to add water. If the water volume detection component 12 detects that the water supply reaches the preset value, the controller shuts down the water supply component 1 to simplify the user operation and improve the user experience.

[0036] Using the direct drinking water machine 13 to supply water can automatically supply water to the steam generator 100, avoiding multiple water additions during use and improving the convenience of use. The water box 12 can supply water to meet the situation where the user does not have a direct drinking water machine. The present application can provide two modes of water supply, namely, water box water supply and direct drinking water machine water supply, to meet the use requirements of different scenarios. The user can choose one of the water box 12 or the direct drinking water machine 13 according to the specific situation, or can choose the mode of water box 12 and direct drinking water machine 13 supplying water at the same time.

[0037] Preferably, when the steam oven is working, the first water inlet branch 10 and the second water inlet branch 11 do not work at the same time, that is, one of the first water inlet branch 10 and the second water inlet branch 11 is connected to the steam generator 100, and the system selects the first water inlet branch 10 by default. If there is no water in the water box 12, the second water inlet branch 11 is started to avoid water storage in the water box 12 for too long and breeding of bacteria.

[0038] In a preferred embodiment of the present invention, Figure 1-4The water supply assembly 1 shown also includes a three-way joint 14, the water box 12 is connected to the first end of the three-way joint 14 to form a first water inlet branch 10, the direct drinking water machine 13 is connected to the second end of the three-way joint 14 to form a second water inlet branch 11, and the third end of the three-way joint 14 is connected to the steam generator 100. The present application provides that the water of the water box 12 and the direct drinking water machine 13 is mixed and then flows out through the three-way joint 14. Preferably, when the user selects the water box 12 and the direct drinking water machine 13 to supply water at the same time, the water box 12 is used first to supply water to avoid bacteria breeding in the water box 12 for a long time.

[0039] In a preferred embodiment of the present invention, Figure 1-4 A pressure limiting valve 15 is connected between the direct drinking water machine 13 and the three-way joint 14 shown. The pressure limiting valve 15 can limit the water pressure of the pure water output by the direct drinking water machine 13 to a certain range, thereby preventing the abnormal water pressure of the direct drinking water machine 13 from having an adverse effect on equipment such as the water pump 21.

[0040] In a preferred embodiment of the present invention, Figure 1-4 A solenoid valve 16 is connected between the pressure limiting valve 15 and the three-way connector 14, and the solenoid valve 16 is connected to a controller, and the controller controls the connection or disconnection of the second water inlet branch 11 according to the solenoid valve 16. When the steam program is started, the solenoid valve 16 is generally closed, and the water in the water box 12 is used first. When the flow meter 21 detects no water flow, it means that there is no water in the water box 12. At this time, the solenoid valve 16 is opened until a preset amount of water is provided to the steam generator 100.

[0041] In a preferred embodiment of the present invention, Figure 1-4 A one-way valve 17 is connected between the water box 12 and the three-way connector 14, and the one-way valve 17 is connected to a controller, and the controller controls the connection or disconnection of the first water inlet branch 10 according to the one-way valve 17. In this way, water in the water box 12 can only flow out but not in, preventing water in the direct drinking water machine 13 from flowing back to the water box 12.

[0042] In a preferred embodiment of the present invention, Figure 1-4 The water supply system shown also includes a water pump 3, a three-way joint 14, a water pump 3, a water volume detection component 2 and a steam generator 100 which are arranged in sequence along the liquid flow direction. The water box 12 or the direct drinking water machine 13 enters the steam generator 100 through the three-way joint 14, the water pump 3 and the flow meter 21. The present application utilizes the pressure limiting valve 15, the flow meter 21 and the pumping time of the water pump 3 to triple limit the water volume and the steam generation volume.

[0043] In a preferred embodiment of the present invention, Figure 1-4The water supply system shown also includes a temperature sensor 4, which is connected to the steam generator 100 and the controller for real-time detection of the temperature of the steam generator 100, wherein the controller can control the start and stop of the water pump 3 in real time according to the signal of the temperature sensor 4. If the temperature sensor 4 detects that the temperature of the steam generator 100 is too high, the signal can be transmitted to the controller, and the controller starts the water pump 3 to add water or increase the water supply of the water pump 3 to avoid dry burning of the steam generator 100.

[0044] A steam-bake machine according to an embodiment of the utility model comprises a water supply system, a steam generator 100, an inner pot 200 and a box body 300 as described above. The water supply system is arranged on the top of the inner pot 200, the steam generator 100 and the inner pot 200 are arranged inside the box body 300, the steam generator 100 is arranged between the inner pot 200 and the box body 300, and the steam outlet end of the steam generator 100 is connected to the inner pot 200. The water supply system can adapt to two modes of water supply: water box water supply and direct drinking water machine water supply. The direct drinking water machine 13 can automatically supply water to the steam generator 100, avoiding multiple water additions during use, and improving the convenience of use. The water supply of the water box 12 can meet the situation where the user does not have a direct drinking water machine, and meet the use requirements of different scenarios. At the same time, the water quantity detection component 2 is used to detect the water supply in real time to avoid excessive water supply and save water resources. If the water box 12 and the direct drinking water machine 13 have no water supply, the water quantity detection component 2 has no flow. At this time, the controller can issue an alarm and prompt according to the signal of the water quantity detection component 2. It can be adapted to both direct drinking water machine and water box to take water, and can also be used by families without direct drinking water machines; it simplifies user operation, and there is no need to add water every time or regularly. Fully automatic water addition improves user experience. It can also prevent the traditional water box 12 from storing too much water or storing water for too long, which may cause bacteria to grow; finally, the design requirements and use effects are achieved.

[0045] In a preferred embodiment of the present invention, Figure 1-4The box body 300 shown includes a rear side plate 3001, a water box 12 and a water level detection component 2 are detachably connected to the top of the inner tank 200, a steam generator 100 is located between the inner tank 200 and the rear side plate 3001, and the water level detection component 2 is connected to the steam generator 100 through a water pipe. The water supply system is arranged above the box body 200, and the water box 12 and the one-way valve 17 are connected to the first end of the three-way joint 14 in sequence. The water outlet end of the direct drinking water machine 13 is connected to the direct drinking water outlet pipe and extends to the top of the inner tank 200, and is connected to the pressure limiting valve 15, the solenoid valve 16 and the second end of the three-way joint 14 in sequence. The third section of the three-way joint 14, the water pump, and the flow meter 21 are connected in sequence with a water pipe, and the water outlet end of the flow meter 21 is connected with a water outlet pipe, which extends backward and downward and is connected to the water inlet of the steam generator 100. The direct drinking water machine 13 can automatically supply water to prevent the steam generator 100 from lacking water, and the above components make full use of the top space of the product.

[0046] In a preferred embodiment of the present invention, Figure 1-4 At least one steam inlet 2001 is provided at the bottom of the inner container 200, so that the steam entering the inner container 200 can quickly and evenly fill the inner container 200.

[0047] The specific principles of this application are:

[0048] If the user has a direct drinking water machine, the water box 12 and the one-way valve 17 are connected in sequence to the first end of the three-way joint 14 by a water pipe to form a first water inlet branch 10; the water outlet end of the direct drinking water machine 13 is connected to a direct drinking water outlet pipe and extends to the top of the inner tank 200, and the direct drinking water outlet pipe is connected to the pressure limiting valve 15, the solenoid valve 16 and the second end of the three-way joint 14 in sequence along the water flow direction to form a second water inlet branch 11.

[0049] When the preheating of the steam-bake combination machine is finished, the controller controls the second water inlet branch 11 to be closed according to the one-way valve 17, so as to give priority to the water in the water box 12 and prevent the water in the water box 12 from being polluted due to long storage time; when the flow meter 21 detects no water flow, the second water inlet branch 11 is opened again, and the pressure limiting valve 15 limits the water output by the direct drinking water machine 12 to a certain pressure range. The flow meter 21 detects the water volume in real time. When the preset water volume is reached, the water supply is stopped to prevent excessive water supply from causing slow steam generation. Therefore, the present application utilizes the triple restrictions of the pressure limiting valve 15, the flow meter 21, and the pumping time of the water pump 3, that is, the water supply and the steam generation can be limited. If during the water supply process, the first water inlet branch 10 and the second water inlet branch 11 cannot detect water flow, it indicates that the water box 12 and the direct drinking water machine 13 are both short of water, and the system will issue an alarm and prompt.

[0050] When the user does not have a direct drinking water machine 13, the water box 11 can be used for water supply. First, add pure water to the water box 12; then, after the preheating of the steam-bake machine is completed, open the first water inlet branch 10. At this time, the pure water in the water box 12 is transported to the steam generator 100 through the one-way valve 17, the water pump 3, and the flow meter 21. The flow meter 21 detects the water volume in real time, and the controller controls the pumping time according to the flow meter and the water pump to prevent excessive water and slow steam generation. The water supply and steam generation can be controlled by the pumping time of the flow meter 21 and the water pump 3. In this way, the steam-bake machine can be applied to different places, and the direct drinking water outlet pipe is reserved at the same time, which is also convenient for subsequent users to have a direct drinking water machine 13 and enable the second water supply branch at any time. The present application realizes that the water supply system can be directly connected to the direct drinking water machine, which can adapt to the two ways of taking water from the direct drinking water machine and the water box, and can also be used by families without direct drinking water machines; it simplifies user operations, and there is no need to add water every time or regularly. The direct drinking water machine automatically adds water to improve the user experience. The control method in the water box 12 is used preferentially to prevent the remaining water in the water box 12 from breeding bacteria, thus saving water resources; and finally the design requirements and use effects are achieved.
