Description

Technical Field

[0001] The invention relates to a cooking device, in particular to an all-in-one steamer, oven and microwave oven. Background Art

[0002] As people's quality of life continues to improve, kitchen appliances are becoming more and more abundant. Microwave ovens, ovens, steamers, etc. have gradually become essential kitchen appliances for family life. These kitchen appliances not only have relatively simple functions, but each product requires a certain amount of kitchen space, and the cost of purchasing them separately is high. In order to effectively utilize kitchen space and reduce purchase costs, people invented the steamer, oven, and microwave oven all-in-one. For example, the "Microwave Steamer and Oven All-in-One" disclosed in the Chinese utility model patent with patent number 201320074461.4 (authorization announcement number CN 203168920 U) includes a body, a door frame and a controller installed on the front of the body, a cavity in the body, a transformer installed on the top of the body, a capacitor connected to the transformer, a magnetron connected to the capacitor, and a waveguide box connected to the magnetron, microwaves are transmitted into the cavity through the waveguide box, a microwave agitator is arranged at the microwave inlet in the cavity, a low-speed motor is connected to the microwave agitator, a water container and a steam generator connected to the water container are installed on the side wall of the body, the steam generator is communicated with the cavity in the body, a heating pipe is arranged on the top of the cavity in the body, and the heating pipe is connected to the controller. Although the microwave oven integrates the functions of a microwave oven, a steamer and an oven, it is not only fully functional and easy to use, but also occupies relatively little kitchen space and has low cost. However, its shortcomings are that the spatial layout design inside the machine body is not reasonable enough, the internal structure is not compact enough, and the heat dissipation effect is not good, which is not conducive to heat dissipation and cooling of electronic components. For example, the "A Steamer Oven Microwave Oven Integrated Machine" disclosed in the Chinese utility model patent with patent number 201621435180.7 (authorization announcement number CN 206586803 U), the waveguide and microwave stirring motor of the microwave generating device of the integrated machine are installed on the right side of the cooking chamber cavity. In the microwave working mode, after testing and verification, it is found that the food close to the microwave outlet is heated very quickly, and the food far away from the microwave outlet is heated slowly. When the food far away from the microwave outlet is heated, the food close to the microwave outlet is very likely to be burnt. In summary, the structure of the existing steamer oven microwave oven integrated machine needs to be further improved. Summary of the invention

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 8 As shown, the steam oven microwave oven of this embodiment comprises a box body 1, a cooking cavity 2 is installed inside the box body 1, and a steam generating device, a microwave generating device and a grill generating device are installed inside the box body 1. A door assembly 20 that can be opened and closed is installed on the front side of the box body 1, and a control panel 100 is provided above the door assembly 20. The control panel 100 can select and control the working mode of the all-in-one machine. An upper mounting plate 10 is installed above the cooking cavity 2, and an air guide assembly 101 for discharging the steam in the cooking cavity 2 is installed on the upper mounting plate 10.

[0027] The steam generating device of this embodiment includes a water tank 31, a water pump 32 and a heating plate 33. The water tank 31 is mounted on the upper mounting plate 10 and hidden behind the control panel 100. The control panel 100 is provided with an opening for the water tank 31 to enter and exit. The water pump 32 is mounted on the water path between the water outlet of the water tank 31 and the water inlet of the cooking cavity 2. The heating plate 33 is mounted on the bottom plate 24 of the cooking cavity 2 and sealed with the bottom plate 24. The water tank 31 and the water pump 32 constitute a water path system. When working in the steaming mode, the water in the water tank 31 is transported to the heating plate 33 inside the cooking cavity 2 by the water pump 32. The water is heated by the heating plate 33 and evaporated to generate steam.

[0028] The microwave generating device of this embodiment adopts a structure of lateral microwave output. The microwave generating device comprises a high-voltage capacitor 41, a high-voltage fuse 42 and a high-voltage transformer 43, a first magnetron 44, a first waveguide 45, a second magnetron 46 and a second waveguide 47, wherein the high-voltage capacitor 41, the high-voltage fuse 42, the high-voltage transformer 43, the first magnetron 44 and the second magnetron 46 are installed on the rear side of the rear wall 23 of the cooking cavity 2, the first waveguide 45 is installed on the left side of the left wall 21 of the cooking cavity 2, and the second waveguide 47 is installed on the right side of the right wall 22 of the cooking cavity 2. A left microwave outlet 211 is opened on the left wall 21 of the cooking cavity 2, a first microwave stirrer (not shown in the figure) matched with the first waveguide 45 is installed at the left microwave outlet 211, a second microwave outlet 221 is opened on the right wall 22 of the cooking cavity 2, and a second microwave stirrer (not shown in the figure) matched with the second waveguide 47 is installed at the right microwave outlet 221. When working in microwave mode, microwaves are emitted into the cooking cavity 2 through the left microwave outlet 211 and the right microwave outlet 221. Microwaves can be emitted alternately from the left and right microwave outlets or from both microwave outlets at the same time, solving the problem of uneven side-outlet microwave heating.

[0029] In order to make the spatial layout of the microwave generating device more reasonable, the first magnetron 44 of this embodiment is arranged at the upper left corner of the rear side of the cooking cavity 2, the second magnetron 46 is arranged at the upper right corner of the rear side of the cooking cavity 2, and the high-voltage capacitor 41, the high-voltage fuse 42, and the high-voltage transformer 43 are arranged at the bottom of the rear side of the cooking cavity 2. The high-voltage transformer 43 is arranged at the lower left corner of the rear side of the cooking cavity 2.

[0030] The structure of the heat dissipation duct system of the microwave generating device is as follows:

[0031] A heat dissipation fan 6 is installed between the high-voltage transformer 43 and the first magnetron 44, and a heat dissipation duct 7 is provided above the first magnetron 44 and the second magnetron 46. The air inlet of the heat dissipation duct 7 faces the first magnetron 44, and the air outlet of the heat dissipation duct 7 faces the second magnetron 46. A first cold air inlet 111 is opened on the left side plate 11 of the box body 1 near the high-voltage transformer 43, a second cold air inlet 131 is opened on the rear plate 13 of the box body 1 near the high-voltage transformer 43, and a hot air outlet 121 is opened at the rear of the right side plate 12 of the box body 1.

[0032] like Figure 8As shown, negative pressure is generated below the heat dissipation fan 6, and cold air outside the machine is sucked in from the first cold air inlet 111 and the second cold air inlet 131. During the inhalation process, the cold air meets the high-voltage transformer 43, and the high-voltage transformer 43 is cooled. After the cold air is sucked into the heat dissipation fan 6, it blows to the first magnetron 44 on the left to cool the first magnetron 44, passes through the heat sink of the first magnetron 44, flows to the heat dissipation duct 7 above, passes through the heat dissipation duct 7, blows to the heat sink of the second magnetron 46 on the right to cool the second magnetron 46, and then is discharged from the hot air outlet 121 of the right side plate 12. The heat dissipation duct system realizes the simultaneous heat dissipation of the dual magnetrons and the high-voltage transformer by one fan, which can reduce costs.

[0033] A hot air blower baffle 9 is installed on the rear side of the rear wall 23 of the cooking cavity 2, a hot air chamber is formed between the hot air blower baffle 9 and the rear wall 23, a ventilation hole 231 capable of preventing microwaves from passing through is opened in the area corresponding to the hot air chamber on the rear wall 23, and the hot air blower baffle 9 is sealed and connected to the rear wall 23. In this way, the hot air blower baffle 9 is installed on the rear side of the rear wall 23 of the cooking cavity 2, so that the matching part of the hot air blower baffle 9 and the rear wall 23 is located outside the microwave energy field, thereby avoiding the occurrence of sparking. At the same time, the sealed connection structure between the hot air blower baffle 9 and the rear wall 23 can prevent microwave leakage.

[0034] The barbecue generating device of this embodiment includes a hot air blower assembly 51 and an upper heating tube 52. The hot air blower assembly 51 includes a hot air blower 511 and a heating tube 512. The hot air blower 511 and the heating tube 512 are both installed in the hot air chamber. The ventilation hole 231 can be divided into an air inlet and an air outlet. Under the action of the hot air blower 511, the hot air in the hot air chamber continuously exchanges heat with the air in the cooking cavity 2, thereby heating the food in the cooking cavity 2. In addition, the upper heating tube 52 is installed on the inner side of the top wall of the cooking cavity 2. The upper heating tube 52 heats the food from the top, making the heating more uniform and sufficient. In addition, in order to solve the problem of condensed water on the top of the cooking cavity, the electric heating film 8 is attached to the inner side of the top wall of the cooking cavity 2 in this embodiment.

[0035] Although the steam generating device, microwave generating device and barbecue generating device of the steamer oven microwave oven share the cooking cavity 2, they are respectively located at different positions inside the box 1. The three are independent of each other, do not interfere with each other, and have high working reliability.
