Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and in particular to a steam oven. Background Art

[0002] A steam oven typically consists of a chamber for cooking and holding food. The chamber is open at the front and features a door that flips up and down. Upper and lower heating pipes are located within the chamber to allow for comprehensive cooking of food. The oven also includes a steam generator, a corresponding water tank, and a water pump connected between the steam generator and the water tank. To bake, the heating pipes are energized to toast the food in the chamber. To steam, the water pump pumps water from the water tank to the steam generator. The high temperature of the steam generator vaporizes the water, forming steam that is sprayed into the chamber to cook the food.

[0003] To avoid having to open the door to access the water tank for refilling, existing steam ovens typically install the water tank at the top of the oven cavity. The cavity then surrounds the outer shell, with a control panel covering the outer end of the water tank, or a spring-loaded water tank mounted to the side of the panel. This separates the water tank from the door, eliminating the need to open the door for refilling. However, installing the water tank at the top requires expanding the space between the shell and the cavity to accommodate the water tank, resulting in a larger space occupied by the water tank, increasing the overall dimensions of the steam oven or reducing the cavity size.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0027] See also Figure 1-6 This embodiment provides a steam oven, comprising a housing 1 and a cooking chamber 2 disposed within the housing 1. The cooking chamber 2 has an opening 21 for placing and removing food. Heating tubes are provided at the top and / or bottom of the cooking chamber 2. When energized, the heating tubes generate heat to bake the food. A door 3 is hingedly connected to the housing 1, which opens and closes the opening 21. When cooking, the door 3 is closed, obstructing the opening 21 and sealing the cooking chamber 2. After cooking, the door 3 is opened to remove the food from the opening 21.

[0028] A water tray 4 and a water tank 5 are provided at the bottom of the cooking chamber 2. The water tray 4 is positioned adjacent to the water tank 5 and is located near the door 3. The water tray 4 is removably connected to the housing 2, positioned from the door 3 toward the back of the housing 5. The water tray 4 is positioned on the outermost side, while the water tank 5 is positioned on the inner side, restrained by the water tray 4. The water tank 5 is not visible from the outside. A steam generator 6 is provided outside the cooking chamber 2 and connected to the water tank 5. The steam generator 6 has a steam outlet 61 and a water return port 62. The steam outlet 61 communicates with the cooking chamber 2, while the water return port 62 communicates with the water tray 4. Specifically, the steam generator 6 includes a steam generator and a water pump (not shown). The water pump draws water from the water tank 5 and transfers it to the steam generator. The steam generator then vaporizes the water into steam, which is then transferred into the cooking chamber 2 through the steam outlet 61. The steam cooks the food, and condensed water from the evaporator flows through the water return port 62 into the water tray 4. Steam ovens generate condensed water backflow during steaming, so a water tray is essential. This embodiment utilizes the remaining space at the bottom of the cooking chamber 2 after the water tray 4 is installed to accommodate the water tank. This maximizes the use of the steam oven's bottom space, avoids the problem of requiring additional space at the top of the cooking chamber as in the prior art, and significantly reduces the water tank's overall space occupation.

[0029] When the user needs to clean the water tray 4, they can directly remove the water tray 4 from the bottom of the steam oven. When the user needs to add water during cooking, they can first remove the water tray 4 and then remove the water tank 5. Compared with the existing steam oven design where the water tank is installed in the door, this can avoid the situation where a large amount of steam overflows when the door is opened and may cause burns to the user, greatly improving the user experience.

[0030] Specifically, see Figure 3-5The water receiving tray 4 is in the shape of a "C". It can be understood that the two ends of the water receiving tray 4 extend outward relative to the middle area, so that the middle area forms a accommodating area, so that when the water tank 5 is placed adjacent to the water receiving tray 4, part of the water tank 5 can be located in the accommodating area, which plays a role in limiting the water tank 5. In this embodiment, a groove 41 is provided on the bottom surface of the middle part of the water receiving tray 4, and one side of the water tank 5 is stuck in the groove 41, further strengthening the limiting effect between the water receiving tray 4 and the water tank 5, and preventing the water tank 5 from shaking or falling off during transportation or moving. In addition, the groove 41 is also equivalent to the invisible handle of the water receiving tray 4, which is convenient for the user to remove and install the water receiving tray 4. In addition, in this embodiment, the water tank 5 is also provided with a handle portion, which is located on one side embedded in the groove 41.

[0031] Further, see Figure 3 and Figure 4 The housing 1 is provided with a bottom plate 11. It is understood that the housing 1 includes side panels surrounding the cooking cavity 2 and the bottom plate 11 located at the bottom of the cooking cavity 2. The side panels and bottom plate 11 enclose a space for the cooking cavity 2. The bottom plate 11 is provided with a receiving cavity 111 and a socket 112. The water tank 5 is removably mounted within the receiving cavity 111. The water tray 4 is provided with a connecting pin 42 that is inserted into the socket 112, thereby detachably connecting the water tray 4 to the bottom plate 11. When a user places their hand in the groove 41 and pulls the water tray 4 outward, the connecting pin 42 disengages from the socket 112, allowing the water tray 4 to be removed. In this embodiment, the bottom plate 11 is provided with side edges 115 at both ends of the side facing the door 3. Two sockets 112 are provided on the side edges 115. Accordingly, connecting pins 42 are provided at each end of the water tray 4 to balance the forces acting on both ends of the water tray 4. The accommodating chamber 111 is open on one side of the door body 3, and the water tank 5 is pushed into the accommodating chamber 111 from this side. The side wall of the accommodating chamber 111 is provided with a connecting port 1111 and a first clip 1112. The water tank 5 is provided with a water outlet 51 and a first card slot 52. The connecting port 1111 is plugged into the water outlet 51. The connecting port 1111 is connected to the steam generating device 6 through a water pipe. The first clip 1112 is inserted into the first card slot 52, thereby fixing the water tank 5 on the bottom plate 11 and further fixing it. In this embodiment, the accommodating chamber 111 is formed on the bottom plate 11 by the left and right side panels and the rear side panel, and the top is not blocked; preferably, the connecting port 1111 is provided on the rear side panel, and the first clip 1112 is provided on the left and right side panels. When the user pulls the water tank 5 outward, the first clip 1112 disengages from the first card slot 52, and the water tank 5 is separated from the bottom plate 11.

[0032] In this embodiment, the water outlet 51 is a spring-loaded structure, and a plug is provided on the connecting port 1111, through which the water outlet 51 is connected. When the water tank is removed, the water outlet 51 is closed and water cannot flow out. This structure is a prior art and will not be described in detail here.

[0033] For further information, please refer to Figure 3 and Figure 4 The bottom plate 11 is provided with a second clip 113, and the water receiving tray 4 is provided with a second slot 43. The second clip 113 is inserted into the second slot 43, thereby making the connection between the water receiving tray and the bottom plate 11 more stable. In this embodiment, the second clip 113 is located on one side of the insertion hole and protrudes outward relative to the bottom plate 11. The second slot 43 is set on the side walls of the water receiving tray 4 at both ends facing the middle. When installing the water receiving tray 4, the connecting pin 4 is first partially inserted into the insertion hole 112. As the water receiving tray 4 is pushed in, the second clip 113 slowly slides into the second slot 43 until the connecting pin 4 is fully inserted into the insertion space 112. At this time, the second clip 113 is buckled with the second slot 43. This design can make the connection between the two ends of the water receiving tray 4 and the bottom plate 11 more stable and less likely to shake.

[0034] In order to prevent the water in the water receiving tray 4 from being excessively filled and causing the connection to be subjected to a large force and fall off, a support portion 114 is further provided on the bottom plate 111, and both ends of the water receiving tray 4 are provided with a limiting boss 44 formed by an inward depression on the bottom surface. When the connecting pin 42 is inserted into the socket 112, the support portion 114 is stuck in the limiting boss 44, thereby supporting the water receiving tray 4.

[0035] Further, see Figure 1 and Figure 5 Support legs 45 are provided at both ends of the bottom plate 11 and the water tray 4. If this embodiment is a tabletop steam oven, the support legs 45 create a certain distance between the oven bottom and the countertop on which it is placed. This not only provides heat dissipation but also facilitates the user's hand movements when removing the water tray 4 and water tank 5. However, in this embodiment, the support legs 45 are provided at both ends of the water tray 4, further facilitating installation by allowing the water tray 4 to be placed directly on the countertop. This also facilitates alignment between the connecting pin 42 and the socket 112, and between the second connector 113 and the second slot 43, making installation easier.

[0036] Further, see Figure 2 and Figure 6 The steam oven of this embodiment also includes a water collecting tank 7, which is connected to the return water port 62 and the water receiving pan 4 respectively. The condensed water of the steam generating device 6 flows from the return water port 62 to the water collecting tank 7, and the water collecting tank 7 is connected to the water receiving pan 4 through a water pipe, so that the condensed water flows into the water receiving pan 4.

[0037] Furthermore, a water collection tank 7 is located at the bottom of the cooking cavity 2. A wastewater outlet (not shown) is provided on the inner wall of the cooking cavity 2, which is connected to the water collection tank 7 via a water pipe. Preferably, the wastewater outlet is provided on the bottom wall of the cooking cavity 2. Since a large amount of condensed water is generated when the steam oven door is opened or after cooking is completed, the wastewater outlet provided on the bottom wall of the cooking cavity 2 allows the condensed water in the cooking cavity 2 to be pumped into the water collection tank 7 through the wastewater outlet, and then flows through the water pipe to the water receiving tray 4. In this embodiment, the water collection tank 7 is located at the intersection of the back and bottom of the cooking cavity 2. This not only fully utilizes the internal space of the oven, but also allows the steam generator 6 to be installed on the back of the cooking cavity 2, so that the water collection tank 7 is also located below the steam generator 6, shortening the distance between the steam generator 6 and avoiding the problem of tangled water pipes. More preferably, in this embodiment, the water collection tank 7 is also provided with a fixing column 73. The water pipe connected to the return water port 62 can be inserted into the fixing column 73 to provide support and diversion, preventing water from flowing into other areas of the oven.

[0038] Specifically, the bottom wall of the water collection tank 7 is provided with an inwardly recessed water collection area 71, and the outer wall of the water collection tank 7 is provided with a drain outlet 72. The water collection area 71 is connected to the drain outlet 72, and the drain outlet 72 is connected to the water receiving tray 4 through a water pipe, so that the water in the water collection tank 7 can be quickly discharged through the water collection area 71, and it is not easy for water to accumulate at the bottom.

[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
