Description

Technical Field

[0001] The present invention relates to the technical field of steam ovens, and particularly to an inner container assembly and a steam oven. Background Art

[0002] When the door of a steam oven is opened after the operation is completed, there will be a small amount of condensed water on the inner surface of the glass inside the door. The condensed water is likely to drip onto the ground, affecting the user experience. The existing technical solution is to provide a condensate water tank near the door at the bottom of the cavity for collecting the condensed water, and a guiding structure is provided below the door for guiding the condensed water on the surface of the door glass to the condensate water tank. After the condensed water slides off the inner glass, it is caught by the condensate water tank.

[0003] If the user forgets to clean the condensed water in the condensate water tank for a long time, the condensed water may deteriorate and emit an odor. Even worse, the condensed water may overflow from the condensate water tank and have an adverse impact on other electrical appliances or cabinets installed below the steam oven. Summary of the Invention

[0004] Based on the problems of residual condensed water and peculiar smell in the existing steam oven after steaming and baking, it is necessary to provide an inner container assembly.

[0005] An inner container assembly includes:

[0006] An inner container body;

[0007] A condensate water tank, provided in front of the entrance of the inner container body and located below the inner container body;

[0008] An essential oil adding device, communicated with the condensate water tank for adding essential oil into the condensate water tank; and

[0009] A heating device, heat-transfer connected to the condensate water tank for heating the mixed liquid of the condensate water and the essential oil in the condensate water tank to evaporate the essential oil and the condensate water.

[0010] With such a setting, not only the problem of residual condensed water is solved, but also the air quality in the kitchen is improved by the aroma released by the heated essential oil. By combining the accelerated volatilization of the essential oil by heating and the evaporation of the condensate water, the heat of the heating device is fully utilized, and the structure is simple. Since there is no need to additionally provide a separate heating device and a volatilization outlet for realizing the rapid volatilization of the essential oil, the influence on the internal space layout of the existing steam oven is small, and the improvement difficulty and cost are both low.

[0011] In one embodiment, the inner container assembly further includes an air pipe with two ends respectively communicated with the condensate water tank and the inner container body, and a cover plate movably installed on the condensate water tank. The cover plate can selectively cover the condensate water tank for sealing or opening the notch of the condensate water tank.

[0012] With such a setting, the condensate sink can be covered by installing a cover plate to form a sealed space. At the same time, the arrangement of the air pipe provides an outlet for the steam in the sealed space. When the heating device works, the steam can enter the inner tank body through the air pipe.

[0013] In one embodiment, the inner tank assembly further includes a first magnetic member installed on the inner tank body and a second magnetic member installed on the cover plate and magnetically attracted to the first magnetic member. When the cover plate is away from the condensate sink, the second magnetic member is magnetically connected to the first magnetic member so that the cover plate is fixedly connected to the inner tank body.

[0014] With such a setting, by providing two magnetic members, the cover plate is temporarily adsorbed on the inner tank body to prevent the cover plate from falling off when the condensate sink collects condensate water.

[0015] In one embodiment, the air pipe includes a first pipe body communicating with the condensate sink, a second pipe body communicating with the inner tank body, and a one-way valve connecting the first pipe body and the second pipe body. The one-way valve is used to allow the gas flowing from the first pipe body to the second pipe body to pass through and block the gas flowing from the second pipe body to the first pipe body.

[0016] With such a setting, the flow direction of the air flow is restricted by the one-way valve, avoiding the problem that the oil fume, odor, etc. in the steam oven flow back into the condensate sink through the air pipe and cause secondary pollution.

[0017] In one embodiment, the air pipe further includes a diffuser nozzle installed at one end of the second pipe body communicating with the inner tank body.

[0018] With such a setting, the steam in the air pipe will spray out in a divergent state when it reaches the diffuser nozzle, so as to fully fill the inner tank body.

[0019] In one embodiment, the heating device includes a heating member installed on the condensate sink and heat-transfer connected to the bottom of the condensate sink, and a temperature measuring member electrically connected to the heating member.

[0020] With such a setting, by monitoring with the temperature measuring member, the dangerous scenario of dry burning of the condensate sink can also be avoided, ensuring safe use.

[0021] In one embodiment, the inner tank assembly further includes an emulsifier adding device communicating with the condensate sink.

[0022] With such a setting, by providing an emulsifier adding device to add emulsifier to the condensate sink, it helps to stably disperse the essential oil into the condensate water, thereby improving the volatilization effect of the essential oil.

[0023] In one embodiment, the inner container assembly further includes an ultrasonic oscillator installed in the condensate water tank.

[0024] With this arrangement, through the ultrasonic oscillator, using the cavitation effect generated by high-frequency sound waves, the essential oil is dispersed into nanoscale droplets. This method can evenly distribute the essential oil in the condensate water to form a stable microemulsion, and further heating this microemulsion can achieve uniform diffusion of the aroma and also help improve the volatilization efficiency of the essential oil.

[0025] In one embodiment, on one side of the condensate water tank near the end, there are a first interface communicating with the essential oil adding device and a second interface communicating with the emulsifier adding device, and the ultrasonic oscillator is installed on one side of the bottom of the condensate water tank near the first interface or the second interface.

[0026] With this arrangement, when the essential oil and the emulsifier just enter the condensate water tank, they can be fully mixed with the condensate water, improving the emulsification efficiency and emulsification effect, and also making full use of the energy of the ultrasonic oscillator.

[0027] This application also provides a steam oven, including:

[0028] A chassis; and

[0029] The inner container assembly as described above, and the inner container assembly is installed in the chassis.

[0030] With this arrangement, the chassis facilitates the assembly and positioning of the various components in the inner container assembly and maintains the stable operation of the inner container assembly. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0040] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0045] When the door of the steam oven is opened after the work is completed, there will be a small amount of condensed water on the inner surface of the inner glass of the door, and the condensed water is likely to drip onto the ground, affecting the user experience. The existing technical solution is to provide a condensate water tank near the door at the bottom of the cavity for collecting the condensed water, and a guiding structure is provided below the door for guiding the condensed water on the surface of the door glass to the condensate water tank. After the condensed water slides off the inner glass, it is caught by the condensate water tank.

[0046] If the user forgets to clean the condensed water in the condensate water tank for a long time, the condensed water may deteriorate and emit an odor, and even the condensed water may overflow from the condensate water tank, having an adverse impact on other electrical appliances or cabinets installed below the steam oven.

[0047] Based on this, it is necessary to provide an inner liner assembly and a steam oven that can clean the condensed water in the condensate water tank in a timely manner and improve the odor problem during the steaming and baking process.

[0048] Please refer to Figure 1 and Figure 2 , Figure 1A schematic structural diagram of a steam oven in an embodiment provided by this application. Figure 2 is Figure 1 The partial enlarged view of the steam oven shown at X.

[0049] The steam oven provided by this application includes a chassis 200 and an inner container assembly installed in the chassis 200. The inner container assembly specifically includes an inner container body 10, a condensate water tank 20, an essential oil adding device 30 and a heating device 40. The condensate water tank 20 is arranged at the entrance of the inner container body 10 and below the inner container body 10. The essential oil adding device 30 is communicated with the condensate water tank 20 and is used to add essential oil into the condensate water tank 20. The heating device 40 is heat-connected to the condensate water tank 20 to heat the mixed liquid of the condensate water and the essential oil in the condensate water tank 20 so as to evaporate the essential oil and the condensate water. In this way, the problem of residual condensate water is solved, and the aroma is released by the heating of the essential oil to improve the air quality in the kitchen. By combining the accelerated volatilization of the essential oil by heating and the evaporation of the condensate water, the heat of the heating device 40 is fully utilized, and the structure is simple. Since there is no need to additionally set up a separate heating device 40 and a volatilization outlet for the rapid volatilization of the essential oil, the impact on the internal space layout of the existing steam oven is small, and the improvement difficulty and cost are low.

[0050] As Figure 2 shown, optionally, in an implementation manner provided by this application, the heating device 40 includes a heating element 41 attached to the bottom of the condensate water tank 20 and a temperature measuring element 42 electrically connected to the heating element 41. By monitoring the temperature measuring element 42, the dangerous scenario of dry burning of the condensate water tank 20 can also be avoided, ensuring the use safety.

[0051] Please refer to Figure 3 , Figure 3 is Figure 1 The schematic structural diagram of the essential oil adding device 30 in the steam oven shown. Specifically, the essential oil adding device 30 specifically includes an essential oil storage box 31, a first solenoid valve 32, and a first diversion pipe 33 and a second diversion pipe 34 respectively connected to the input end and the output end of the solenoid valve. The other end of the first diversion pipe 33 is communicated with the essential oil storage box 31, and the other end of the second diversion pipe 34 is communicated with the condensate water tank 20. The essential oil can be selectively input into the condensate water tank 20 through the first solenoid valve 32. Optionally, in an implementation manner provided by this application, an essential oil replenishment interface 301 is further opened above the essential oil storage box 31, which facilitates self-addition. It can be understood that in other embodiments, the essential oil can also be replenished by replacing the essential oil storage box 31.

[0052] In some cooking scenarios, such as after cooking seafood, if the user does not clean it in time or the cleaning is not in place, it is inevitable that there will be a pungent smell remaining in the steam oven, especially in the inner container, which will affect the user's next cooking experience and the air quality in the kitchen.

[0053] Based on this, please refer to Figure 5 , Figure 5 as Figure 1 a schematic structural view of the steam oven shown in another perspective. In an embodiment provided by the present application, the inner container assembly further includes an air pipe 50 and a cover plate 60. Two ends of the air pipe 50 are respectively communicated with the condensation water tank 20 and the inner container body 10. The cover plate 60 is movably installed on the condensation water tank 20, and the cover plate 60 can selectively cover the condensation water tank 20 for covering or opening the notch of the condensation water tank 20. When the notch of the condensation water tank 20 is covered by the cover plate, the steam of the mixed liquid of essential oil and condensed water enters the inner container through the air pipe 50. By closing the condensation water tank 20 with the cover plate 60 and then introducing the steam of the mixed liquid of essential oil and condensed water into the inner container body 10 through the air pipe 50, the odor environment in the inner container body 10 is improved, and the air quality in the inner container body 10 is enhanced.

[0054] As Figure 5 shown, considering the problem of backflow in the air pipe 50, in order to prevent oil fume, odor, etc. during the steaming and baking process from flowing back into the condensation water tank 20, in an embodiment provided by the present application, the air pipe 50 includes a first pipe body 51, a second pipe body 52 and a one-way valve 53. The first pipe body 51 is communicated with the condensation water tank 20, the second pipe body 52 is communicated with the inner container body 10, and the one-way valve 53 connects the first pipe body 51 and the second pipe body 52. The one-way valve 53 is used to allow the gas flowing from the first pipe body 51 to the second pipe body 52 to pass through and block the gas flowing from the second pipe body 52 to the first pipe body 51. By means of the one-way valve 53, the flow direction of the air flow is restricted, and the problem that oil fume, odor, etc. in the steam oven flow back into the condensation water tank 20 through the air pipe 50 and cause secondary pollution is avoided. Further, in order to facilitate the diffusion of fragrance, in an embodiment provided by the present application, the air pipe 50 further includes a diffusion nozzle 54 installed at one end of the second pipe body 52 communicated with the inner container body 10. The steam in the air pipe 50 will spray out in a divergent state when it reaches the diffusion nozzle 54, so as to fully fill the inner container body 10.

[0055] Please refer to again Figure 2, Considering that the cover plate 60 needs to be kept open during the normal process of the condensate water tank 20 collecting condensate water. Optionally, in an embodiment provided by the present application, the inner container assembly further includes a first magnetic member 71 installed on the inner container body 10 and a second magnetic member 72 installed on the cover plate 60 and magnetically attracted to the first magnetic member 71. When the cover plate 60 is away from the condensate water tank 20, the second magnetic member 72 is magnetically connected to the first magnetic member 71 so that the cover plate 60 can be selectively fixedly connected to the inner container body 10. By providing two magnetic members to temporarily adsorb the cover plate 60 on the inner container body 10, it is prevented that the cover plate 60 drops when the condensate water tank 20 collects condensate water. Optionally, the cover plate 60 can also be rotatably connected to the condensate water tank 20 or the inner container body 10 through a rotating shaft structure, thereby avoiding the problem of loss of the cover plate 60.

[0056] Considering that the density of essential oil is usually less than that of water, when the essential oil is added to the condensate water tank, it usually floats on the surface of the condensate water and is usually concentrated in a large droplet state, which affects the volatilization efficiency of the essential oil and is also easy to stick to the inner wall of the condensate water tank and cause residue problems.

[0057] Based on this, in an embodiment provided by the present application, the inner container assembly further includes an emulsifier adding device 80 communicated with the condensate water tank 20. Please refer to Figure 4 , Figure 4 For Figure 1 the structural schematic diagram of the emulsifier adding device 80 in the steam oven shown, the emulsifier adding device 80 includes an emulsifier storage box 81, a second solenoid valve 82, and a third diversion pipe 83 and a fourth diversion pipe 84 respectively communicated with the input end and the output end of the second solenoid valve 82. The other end of the third diversion pipe 83 is communicated with the emulsifier storage box 81, and the other end of the fourth diversion pipe 84 is communicated with the condensate water tank 20. Based on this structure, by adding an emulsifier to the condensate water tank 20, it helps to stably disperse the essential oil into the condensate water, thereby improving the volatilization effect of the essential oil. The emulsifier adopts natural emulsifiers such as lecithin or soy protein, etc. It can be understood that, in an embodiment provided by the present application, an emulsifier replenishment interface 801 is also opened above the emulsifier storage box 81.

[0058] In order to further improve the emulsification effect of the emulsifier, please refer to again Figure 2 , Optionally, in an embodiment provided by the present application, the inner container assembly further includes an ultrasonic oscillator 90 installed on the condensate water tank 20. Through the ultrasonic oscillator 90, by using the cavitation effect generated by high-frequency sound waves, the essential oil is dispersed into nano-sized droplets. This method can evenly distribute the essential oil in the condensate water to form a stable microemulsion, and further heating the microemulsion can achieve uniform diffusion of the aroma and also helps to improve the volatilization efficiency of the essential oil.

[0059] Please refer toFigure 6 , Figure 6 This is a schematic structural diagram of a condensation water tank 20 provided by the present application. Since the length of the condensation water tank 20 is relatively long, in order to better display the details of the condensation water tank 20, the middle repeated part of the condensation water tank 20 is folded in the figure, and only the structures near both ends of the condensation water tank 20 are shown. Optionally, a plurality of interfaces are provided on the side wall of the condensation water tank 20: a first interface 201 for cooperating with the second diversion pipe 34, a second interface 202 for cooperating with the fourth diversion pipe 84, and a third interface 203 for cooperating with the first pipe body 51. The first interface 201 and the second interface 202 are arranged near one end of the condensation water tank 20, and the third interface 203 is arranged near the other end of the condensation water tank 20. It can be understood that in order to prevent condensed water from entering the first pipe body 51, in an embodiment provided by the present application, the third interface 203 is located at a position near the upper part of the side wall of the condensation water tank 20. Further, in combination with Figure 2 and Figure 6 , the ultrasonic oscillator 90 is installed on one side of the bottom of the condensation water tank 20 near the first interface 201 and the second interface 202, so that the essential oil and the emulsifier can be combined with the condensed water when they just enter the condensation water tank 20, improving the emulsification efficiency and emulsification effect, making full use of the energy of the ultrasonic oscillator 90, and avoiding energy loss of the ultrasonic oscillator 90.

[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0061] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
