Description

Technical Field

[0001] This invention relates to a cooking device, and more particularly to a door structure for a cooking device. Background Technology

[0002] Currently, steam oven doors consist of an outer glass and an inner glass, with the inner glass fixed to the outer glass using screws and other fasteners. Since the inner glass is in direct contact with the oven's interior, it easily becomes dirty during cooking, requiring users to disassemble and clean it. However, disassembling or installing the inner glass requires tools such as screwdrivers, making it inconvenient. To improve heat insulation, some steam oven doors use a three-layer glass structure consisting of an outer, middle, and inner glass. The problem with this is that the glass is fixed with screws, making it difficult to clean. When water or dirt gets inside the glass, users cannot clean it promptly, affecting the door's appearance.

[0003] To address the aforementioned issues, existing technology provides an oven door that is easy to install. This oven door includes an outer glass layer with two opposing mounting blocks spaced parallel to each other. The two mounting blocks are located near the two edges of the outer glass layer. An inner glass layer, spaced apart from the outer glass layer, is also provided on each mounting block. An air vent bracket is located at the top of each mounting block. The upper end of the inner glass layer is inserted into the air vent bracket, and the lower end of the inner glass layer is inserted into the mounting block. Each mounting block has a spring-loaded buckle that locks the air vent bracket. Each mounting block has one spring-loaded buckle, which is individually mounted on the mounting block. The air vent bracket has two unlocking blocks that can push the spring-loaded buckles to unlock. These unlocking blocks are located at the left and right ends of the air vent bracket and correspond one-to-one with the spring-loaded buckles. Each unlocking block has a spring that can spring back to its original position. The spring is sleeved on the unlocking block, with one end pressing against the air vent bracket. During installation, simply place the inner glass layer on the mounting block, then cover it with the air vent bracket. The air vent bracket presses against the elastic buckle, locking it in place. To disassemble, press the unlocking block to release the clip. Then, remove the air vent bracket and the inner glass layer in sequence. This allows for quick and easy removal and installation of the inner glass layer without the need for tools. However, the oven door's design, which uses elastic buckles, latches, unlocking blocks, and return springs to lock and unlock the air vent bracket, involves many parts, making assembly cumbersome, time-consuming, and inefficient.

[0004] In addition, when the steam oven ends its steaming mode and the door is opened, a small amount of condensation will appear on the glass surface of the door. This condensation can easily drip onto the ground, affecting the user experience. Existing steam ovens have a condensation tank at the bottom of the cavity near the door to collect the condensation, and a condensation guiding structure is located below the door to guide the condensation on the glass surface into the condensation tank. However, it is not possible to guarantee that all the condensation on the glass surface will enter the condensation tank during the opening process. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a door structure for a cooking device that is easy to disassemble and clean, in light of the above-mentioned existing technology.

[0006] The second technical problem to be solved by the present invention is to provide a door structure for a cooking device that prevents condensation on the glass surface of the door from dripping onto the ground during the opening of the door, in light of the aforementioned existing technology.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is as follows: the door structure of the cooking device includes an outer glass assembly and an inner glass assembly, the left and right sides of the outer glass assembly are respectively a rotating side and an opening / closing side, characterized in that: the inner glass assembly also has a rotating side and an opening / closing side, the rotating side of the inner glass assembly is rotatably connected to the rotating side of the outer glass assembly through the rotating connector, and the opening / closing side of the inner glass assembly is fastened to the opening / closing side of the outer glass assembly through a fastener.

[0008] Preferably, the door structure of the cooking device further includes a middle glass assembly disposed between the outer glass assembly and the inner glass assembly. The middle glass assembly also has a rotating side and an opening / closing side. The rotating side of the middle glass assembly is rotatably connected to the rotating side of the outer glass assembly through the rotating connector. The opening / closing side of the middle glass assembly is fastened to the opening / closing side of the outer glass assembly through the fastening member.

[0009] The rotating connector can have various structures. Preferably, a hook bracket is installed on the rotating side of the outer glass assembly. The rotating connector consists of an upper hook and a lower hook installed on the hook bracket. Both the middle glass assembly and the inner glass assembly are rotatably connected to the upper hook and the lower hook.

[0010] In order to enable the middle glass assembly and the inner glass assembly to be rotatably connected to the upper hook and the lower hook, preferably, the rotating side of the middle glass assembly is provided with an upper hinge and a lower hinge, the rotating side of the inner glass assembly is provided with an upper hinge and a lower hinge, the upper hinge and the upper hinge are mounted on the upper hook, and the lower hinge and the lower hinge are mounted on the lower hook.

[0011] Further preferably, both the upper hook and the lower hook are L-shaped hooks. The horizontal section of the L-shaped hook is mounted on the hook bracket, and the vertical section of the L-shaped hook is used to install the upper hinge of the middle glass, the upper hinge of the inner glass, the lower hinge of the middle glass, and the lower hinge of the inner glass.

[0012] To determine the lowest position of the middle and inner glass components and prevent wear caused by hard contact between the hinges and the horizontal section of the L-shaped hook during rotation, a lower positioning block is provided at the lower part of the vertical section of the lower hook. The lower hinge of the middle or inner glass component is supported on the lower positioning block. The lower positioning block can be sleeved on the lower hook or it can be an integral part of the lower hook.

[0013] The fastener can have various structures. To avoid the glass edge directly engaging with the metal buckle and causing breakage, preferably, the fastener includes a buckle and a positioning frame that engage with each other. The buckle is located on the opening and closing side of the outer glass assembly, and the positioning frame is located on the opening and closing sides of the middle glass assembly and the inner glass assembly.

[0014] Further preferably, the buckle includes an upper buckle and a lower buckle, and the positioning frame includes an upper positioning frame and a lower positioning frame for the middle glass assembly, as well as an upper positioning frame and a lower positioning frame for the inner glass assembly.

[0015] In order to secure the middle glass assembly and the inner glass assembly along the vertical direction of the glass, the buckle has a middle glass stop rib and an inner glass stop rib.

[0016] To prevent relative movement between the middle glass assembly and the inner glass after they are fastened together, a middle glass limiting bracket is provided on the side of the middle glass assembly facing the inner glass assembly, and an inner glass limiting bracket is provided on the side of the inner glass assembly facing the middle glass assembly. The middle glass limiting bracket and the inner glass limiting bracket abut against each other, or a limiting sealing ring is installed between the middle glass limiting bracket and the inner glass limiting bracket. The limiting seal also ensures that the distance between the middle glass assembly and the inner glass assembly is constant.

[0017] In order to enable the outer glass assembly to rotate relative to the door frame, the outer glass assembly has an upper pivot hole at the top of the rotating side and a lower pivot hole at the bottom of the rotating side, and the outer glass assembly can rotate around the axis of the upper pivot hole and the lower pivot hole.

[0018] The technical solution adopted by the present invention to solve the second technical problem mentioned above is as follows: a water receiving trough is installed at the bottom of the middle glass assembly and the inner glass assembly, and a water outlet is opened at the bottom of the water receiving trough. A water outlet opening and closing mechanism is installed below the water receiving trough. When the door is closed, the water outlet opening and closing mechanism opens the water outlet, and when the door is open, the water outlet opening and closing mechanism closes the water outlet.

[0019] The outlet opening and closing mechanism can have various structures. Preferably, the outlet opening and closing mechanism includes a rotating shaft, a torsion spring, and a pressure plate. The rotating shaft is installed at the bottom of the water receiving tank. The torsion spring and the pressure plate are sleeved on the rotating shaft. One end of the torsion spring abuts against the water receiving tank, and the other end of the torsion spring abuts against the bottom of the pressure plate. When the door is closed, the pressure plate, after being pressed, can overcome the torsion force of the torsion spring and rotate downward around the rotating shaft, thereby opening the outlet. When the door is open, the pressure plate, under the torsion force of the torsion spring, rotates upward around the rotating shaft and resets, thereby closing the outlet.

[0020] To improve the sealing performance between the pressure plate and the outlet, the outlet opening and closing mechanism also includes a sealing ring, which is installed around the pressure plate.

[0021] Preferably, the bottom of the water receiving tank is provided with a rotating shaft bracket, there are two rotating shaft brackets and they are respectively located on both sides of the water outlet, and the two ends of the rotating shaft are installed on the corresponding rotating shaft brackets.

[0022] In order to enable the shaft to rotate flexibly and improve wear resistance, the outlet opening and closing mechanism also includes bushings installed at both ends of the shaft, and the bushings are installed on the corresponding shaft brackets.

[0023] Compared with the prior art, the advantages of the present invention are as follows: the rotating side of the inner glass assembly of the door structure of the cooking device is rotatably connected to the rotating side of the outer glass assembly through a rotating connector, and the opening and closing side of the inner glass assembly is fastened to the opening and closing side of the outer glass assembly through a fastener. The inner glass can be easily removed from the outer glass. When cleaning is required, the inner glass assembly can be opened for cleaning, which can effectively remove water stains and dirt from the glass. In addition, by installing a water collection trough at the bottom of the door, when the door is closed, the water outlet at the bottom of the water collection trough is opened by the water outlet opening and closing mechanism, and when the door is opened, the water outlet opening and closing mechanism closes the water outlet, thereby preventing condensate water in the water collection trough from dripping onto the ground and ensuring that no condensate water drips onto the surface of the door glass during the opening of the door, thus improving the user experience.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 5 As shown, the door structure of the cooking device in this embodiment includes an outer glass assembly 1, a middle glass assembly 2, and an inner glass assembly 3. Figure 2 The direction indicated by the middle arrow C is to the right. The right side of the outer glass assembly 1 is the rotating side, and the left side is the opening and closing side. The outer glass assembly 1 has an upper pivot hole 11 at the top of the rotating side and a lower pivot hole (not shown in the figure) at the bottom of the rotating side. The outer glass assembly 1 can rotate around the axis of the upper pivot hole 11 and the lower pivot hole to realize the opening and closing of the door. A handle 10 is installed on the opening and closing side of the outer glass assembly 1 for the convenience of users to open the door.

[0036] Both the middle glass assembly 2 and the inner glass assembly 3 have a rotating side and an opening / closing side. The rotating side of the middle glass assembly 2 is rotatably connected to the rotating side of the outer glass assembly 1 via a rotating connector, and the rotating side of the inner glass assembly 3 is rotatably connected to the rotating side of the outer glass assembly 1 via a rotating connector, with the rotating connector located close to the rotating side. The opening / closing sides of both the middle glass assembly 2 and the inner glass assembly 3 are fastened to the opening / closing side of the outer glass assembly 1 by fasteners.

[0037] like Figure 3As shown, a hook bracket 4 is installed on the rotating side of the outer glass assembly 1. An upper hook 51 and a lower hook 52 are installed on the hook bracket 4. The upper hook 51 and the lower hook 52 constitute a rotating connector. The middle glass assembly 2 and the inner glass assembly 3 are both rotatably connected to the upper hook 51 and the lower hook 52. Specifically, the upper hook 51 and the lower hook 52 are both L-shaped hooks, and the horizontal section of the L-shaped hook is installed on the hook bracket 4. The rotating side of the middle glass assembly 2 is provided with an upper hinge 21 and a lower hinge 22, and the rotating side of the inner glass assembly 3 is provided with an upper hinge 31 and a lower hinge 32. The upper hinge 21 and the upper hinge 31 are cross-fitted and are both installed on the vertical section of the upper hook 51. The lower hinge 22 and the lower hinge 32 are cross-fitted and are both installed on the vertical section of the lower hook 52. That is, the vertical sections of the hinge and the hook are coaxially fitted. In order to determine the lowest position of the middle glass assembly 2 and the inner glass assembly 3 and to avoid wear caused by hard contact between the hinges of the middle glass assembly 2 and the horizontal section of the L-shaped hook when they rotate, a lower positioning block 6 is sleeved on the lower part of the vertical section of the lower hook 52. The lower positioning block 6 plays a positioning role and can be made of plastic. In this embodiment, the lower hinge 22 of the middle glass is supported on the lower positioning block 6.

[0038] The fastening components in this embodiment include interlocking buckles and positioning frames. The buckles are located on the opening / closing side of the outer glass assembly 1, and the positioning frames are located on the opening / closing sides of the middle glass assembly 2 and the inner glass assembly 3. Specifically, the buckles include an upper buckle 71 and a lower buckle 72, both of which are thin sheet metal parts with a certain deformation capacity under pressure. Both the upper buckle 71 and the lower buckle 72 have a middle glass stop rib 73 and an inner glass stop rib 74. The positioning frames include an upper positioning frame 23 for the middle glass, a lower positioning frame 24 for the middle glass, an upper positioning frame 33 for the inner glass, and a lower positioning frame 34 for the inner glass. The upper positioning frame 23 and the lower positioning frame 24 for the middle glass are located on the opening / closing side of the middle glass assembly 2, and the upper positioning frame 33 and the lower positioning frame 34 for the inner glass are located on the opening / closing side of the inner glass assembly 3. After installation, taking the middle glass assembly 2 as an example, the upper positioning bracket 23 and the lower positioning bracket 24 of the middle glass are fixed to the edge of the middle glass, respectively cooperating with the upper clip 71 and the lower clip 72 to prevent the edge of the middle glass from directly engaging with the metal clips and causing breakage. The fastening structure of the inner glass assembly 3 and the outer glass assembly 1 is the same, and will not be described in detail here.

[0039] Additionally, a middle glass limiting bracket 25 is provided on the side of the middle glass assembly 2 facing the inner glass assembly 3, and an inner glass limiting bracket 35 is provided on the side of the inner glass assembly 3 facing the middle glass assembly 2. After the door is installed, the middle glass limiting bracket 25 and the inner glass limiting bracket 35 abut against each other. (See [reference]). Figure 9In addition, a limiting sealing ring (not shown in the figure) can be installed between the middle glass limiting bracket 25 and the inner glass limiting bracket 35 for buffering. This can ensure that the distance between the middle glass assembly 2 and the inner glass assembly 3 is constant and prevent them from moving to each other.

[0040] The installation sequence of this door structure is as follows:

[0041] First, the upper and lower hinges of the middle glass assembly 2 and the inner glass assembly 3 are cross-fitted, with the hinge of the middle glass assembly 2 positioned below the corresponding hinge of the inner glass assembly 3. Then, the hinges of both assemblies are fitted together onto the upper hook 51 and the lower hook 52. The middle glass assembly 2 is rotated so that the upper positioning bracket 23 of the middle glass is engaged in the upper latch 71, and the lower positioning bracket 24 of the middle glass is engaged in the lower latch 72. Finally, the inner glass assembly 3 is rotated so that the upper positioning bracket 33 of the inner glass is engaged in the upper latch 71, and the lower positioning bracket 34 of the inner glass is engaged in the lower latch 72. The middle glass stop ribs 73 and the inner glass stop ribs 74 on the upper latch 71 and the lower latch 72 respectively fix the middle glass assembly 2 and the inner glass assembly 3 along the direction perpendicular to the glass, completing the assembly. When it is necessary to disassemble the door to clean the glass, the operation steps are the reverse of the above steps.

[0042] like Figures 6 to 10 As shown, in this embodiment, the door structure of the cooking device has a water receiving trough 8 installed at the bottom of the middle glass assembly 2 and the inner glass assembly 3. The bottom of the water receiving trough 8 has a water outlet 81. A water outlet opening and closing mechanism 9 is installed below the water receiving trough 8. When the door is closed, the water outlet opening and closing mechanism 9 opens the water outlet 81. When the door is open, the water outlet opening and closing mechanism 9 closes the water outlet 81.

[0043] The bottom of the water receiving tank 8 is provided with a rotating shaft support 82. There are two rotating shaft supports 82, located on both sides of the water outlet 81. The water outlet opening and closing mechanism 9 in this embodiment is a rotating mechanism, specifically including a rotating shaft 91, a torsion spring 92, a pressure plate 93, a sealing ring 94, and a bushing 95. The bushing 95 is fitted onto both ends of the rotating shaft 91 and installed on the corresponding rotating shaft supports 82, thus the rotating shaft 91 is installed on the corresponding rotating shaft supports 82. The torsion spring 92 and the pressure plate 93 are fitted onto the rotating shaft 91. One end of the torsion spring 92 abuts against the side wall of the water receiving tank 8, and the other end of the torsion spring 92 abuts against the bottom of the pressure plate 93. The sealing ring 94 is installed around the pressure plate 93, and the sealing ring 94 is used to improve the sealing between the pressure plate 93 and the water outlet 81.

[0044] like Figure 10 As shown, the cooking device in this embodiment is a commercial steam oven, which includes a cooking cavity and a door installed on the front side of the cooking cavity. The door includes an outer glass assembly 1, a middle glass assembly 2, and an inner glass assembly 3. A water collection tank 8 is used to collect condensate water that condenses on the middle glass assembly 2 and the inner glass assembly 3.

[0045] During cooking, when the door is closed, the front end 931 of the pressure plate contacts the cooking cavity. After being pressed, the pressure plate 93 overcomes the torque of the torsion spring 92 and rotates downward around the pivot 91, thereby opening the water outlet 81 at the bottom of the water tank 8. At this time, the condensate in the water tank 8 can flow through the water outlet 81 to the condensate tank of the whole machine (not shown in the figure). After cooking, when the door is opened, the front end 931 of the pressure plate is no longer under pressure. Under the torque of the torsion spring 92, the pressure plate 93 rotates upward around the pivot 91 and returns to its original position until it hits the bottom of the water outlet 81 of the water tank 8 and closes the water outlet 81. At this time, it can prevent the condensate in the water tank 8 from dripping onto the ground, ensuring that no condensate drips onto the surface of the glass assembly 2 and the inner glass assembly 3 during the opening of the door.

[0046] Although the door structure of this embodiment has three layers of glass components, the present invention also protects a double-layer door structure consisting only of an outer glass component and an inner glass component.

[0047] The door structure of this embodiment is not only suitable for commercial steam ovens, but also for other cooking equipment such as steamers and ovens.

[0048] Furthermore, the specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
