Description

Technical Field

[0001] The invention relates to the technical field of cooking utensils, in particular to a door structure and cooking equipment. Background Art

[0002] Cooking equipment, such as a steam oven, generally includes a box body with a cooking space, a door body connected to the box body and a water tank for supplying water during the cooking process. Existing cooking equipment generally requires taking out the water tank to add water, which is complicated to operate, and the repeated taking out and putting in of the water tank is prone to water leakage.

[0003] Furthermore, when the cooking time is long, the temperature in the cooking space will cause the temperature on the door body to gradually increase, and there is a risk of scalding the user when the user touches the door body. Summary of the invention

[0004] Based on this, it is necessary to provide a door structure and cooking equipment to address the above problems, so as to facilitate the addition of water to the water tank and prevent the user from being scalded when touching the door.

[0005] The present invention first provides a door structure for cooking equipment, the cooking equipment comprising a box body and a door structure that can be opened and closed on the box body, the cooking equipment also comprising a water tank assembly arranged at the bottom of the box body, the door structure comprising: a door body, provided with a water adding chamber, a heat dissipation chamber and a water adding pipeline, the bottom of the water adding chamber is connected to the heat dissipation chamber, one end of the water adding pipeline is connected to the bottom of the water adding chamber and / or the bottom of the heat dissipation chamber, when the door structure is in a covered state, the other end of the water adding pipeline is connected to the water tank assembly; and a handle, which is arranged on the outer surface of the door body and provided with a water adding port connected to the water adding chamber.

[0006] In the above-mentioned door body structure, when it is necessary to add water to the water tank assembly, the door body structure is controlled to be closed, and water is added to the water adding chamber through the water adding port on the handle. Part of the water in the water adding chamber flows directly into the water tank assembly through the water adding pipe, and the remaining water flows into the heat dissipation chamber first to reduce the temperature in the heat dissipation chamber and the outer surface of the door body to avoid burns when touching the door body. The water in the heat dissipation chamber then flows into the water tank assembly through the water adding pipe, so that water can be added to the water tank assembly through the handle and the door body without taking out the water tank assembly. The operation is simple and convenient, which improves the user's water adding experience. Even during cooking, the water tank assembly can be added with water to achieve a single long-term cooking of the cooking equipment, and it can also avoid water leakage caused by repeated removal and placement of the water tank assembly.

[0007] In one embodiment, the door body is also provided with a connecting pipe, the two ends of which are respectively connected to the bottom of the water adding chamber and the top of the heat dissipation chamber, and the door body structure also includes a switch component, which is used to control the on-off of the connecting pipe.

[0008] With such a configuration, when the temperature in the heat dissipation cavity exceeds a preset maximum value, the control switch component will open the connecting pipe, and part of the water in the water-adding cavity will be able to flow into the heat dissipation cavity through the connecting pipe, so as to reduce the temperature in the heat dissipation cavity and the outer surface of the door body; when the temperature in the heat dissipation cavity is lower than the preset minimum value, the control switch component will close the connecting pipe, and the water in the water-adding cavity will not be able to flow into the heat dissipation cavity, so as to prevent the water in the heat dissipation cavity from affecting the temperature rise rate in the cooking space.

[0009] In one embodiment, the connecting pipeline includes a first connecting section and a second connecting section, the first connecting section extends along the height direction of the door body, and both ends are respectively connected to the outside and the heat dissipation chamber, the first connecting section also includes a water inlet connected to the water filling chamber and a water outlet connected to the second connecting section, and the end of the second connecting section away from the water outlet is connected to the heat dissipation chamber; the switch component includes a piston, and the piston can be slidably arranged in the first connecting section to connect or disconnect the water inlet with the water outlet.

[0010] With such arrangement, the piston can be automatically controlled to slide in the first connecting section through temperature changes in the heat dissipation cavity, so as to connect or disconnect the water inlet and the water outlet. The structure is simple and the cost is low.

[0011] In one of the embodiments, the door structure further includes a nozzle disposed in the middle of the top of the heat dissipation cavity and connected to the bottom of the water adding cavity.

[0012] With such arrangement, the water in the second connecting section can be sprayed evenly into the heat dissipation cavity in all directions through the nozzle to enhance the cooling effect.

[0013] In one of the embodiments, the door body structure further includes a water retaining member disposed in the heat dissipation cavity and located at the bottom of the nozzle, the water retaining member extends along the width direction of the door body, and the water retaining member is provided with a plurality of water outlet holes arranged at intervals.

[0014] With such an arrangement, water sprayed from the nozzle falls on the water retaining member and flows downward evenly through the multiple water outlet holes on the water retaining member, thereby improving the uniformity of water in the heat dissipation cavity and enhancing the cooling effect.

[0015] In one of the embodiments, the door body includes a window area opposite to the heat dissipation cavity, and the inner wall of the heat dissipation cavity is provided with a hydrophobic layer.

[0016] With such a configuration, the hydrophobic layer enables water droplets hanging on the inner wall of the heat dissipation cavity to quickly flow to the bottom of the heat dissipation cavity, preventing the water droplets from affecting the user's observation of the cooking space through the window area, thereby ensuring the visual effect of the window area.

[0017] In one embodiment, the door structure also includes a partition protruding from the bottom wall of the water adding chamber, and the partition divides the water adding chamber into a first area and a second area; a first outlet connected to the water adding pipeline is provided at the bottom of the first area, and a second outlet connected to the heat dissipation chamber is provided at the bottom of the second area, and the water adding port is provided in the second area.

[0018] Such an arrangement can ensure that there is enough water in the second area to dissipate the heat in the heat dissipation cavity during the cooking process, without the need for the user to add water repeatedly, thereby improving the user experience.

[0019] In one embodiment, the door structure further comprises a cover assembly which is openably arranged at the water inlet; and / or the cross-sectional area of ​​the water inlet is greater than or equal to 50 cm 2 .

[0020] With such a configuration, the cover assembly can prevent external dust and other impurities from falling into the water adding chamber or the heat dissipation chamber through the water adding port, causing difficulty in cleaning or affecting cooking; when the user adds water to the water adding port, the water can flow quickly into the water adding chamber, thereby improving the water adding efficiency and also preventing water from overflowing from the water adding port.

[0021] The present invention further provides a cooking device, comprising: a box body; a water tank assembly, arranged at the bottom of the box body; and a door structure as described above, which is openably and closably arranged at the box body.

[0022] With such an arrangement, the existing space at the bottom of the box body can be utilized to increase the volume of the water tank assembly to meet the needs of single long-term cooking without increasing the overall volume of the cooking device.

[0023] In one embodiment, the water tank assembly includes a water tank body and a water level detection assembly disposed on the water tank body.

[0024] With such arrangement, the water level detection assembly can facilitate the user to understand the water level in the water tank body. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Cooking equipment, such as steam ovens, usually includes a box with a cooking space, a door connected to the box that can be opened and closed, and a water tank for supplying water during the cooking process. Existing cooking equipment usually requires taking out the water tank to add water, which is complicated to operate. When the water tank is repeatedly taken out and put in, it is easy to leak due to improper placement of the water tank or wear of the water tank sealing ring. In addition, when the cooking time is long, the temperature in the cooking space will cause the temperature on the door to gradually rise. When the user touches the door, there is a risk of scalding the user.

[0043] In order to solve the above problems, Figures 1 to 10 As shown, the present invention first provides a door structure 100 to facilitate the filling of water into the water tank and prevent the user from being scalded when touching the door.

[0044] like Figure 1 and Figure 8 As shown, the door structure 100 is used for a cooking device, which includes a box body 200 and a door structure 100 that can be opened and closed on the box body 200. The door structure 100 can form a closed cooking space with the box body 200 in a closed state to heat food in the cooking space. The cooking device also includes a water tank assembly 300 disposed at the bottom of the box body 200, and the water tank assembly 300 is used to supply water to the cooking space during the cooking process.

[0045] like Figure 1 , Figure 2 and Figure 8 As shown, specifically, the door body structure 100 includes a door body 1 and a handle 2, wherein: the door body 1 is provided with a water adding chamber 11, a heat dissipation chamber 12 and a water adding pipe 13, the bottom of the water adding chamber 11 is connected with the heat dissipation chamber 12, one end of the water adding pipe 13 is connected with the bottom of the water adding chamber 11 and the bottom of the heat dissipation chamber 12, and when the door body structure 100 is in a closed state, the other end of the water adding pipe 13 is connected with the water tank assembly 300; the handle 2 is arranged on the outer surface of the door body 1, and is provided with a water adding port 21 connected with the water adding chamber 11.

[0046] In the door body structure 100 provided in the embodiment of the present invention, when it is necessary to add water to the water tank assembly 300, the door body structure 100 is controlled to be closed, and water is added to the water adding chamber 11 through the water adding port 21 on the handle 2. Part of the water in the water adding chamber 11 flows directly into the water tank assembly 300 through the water adding pipe 13, and the remaining water flows into the heat dissipation chamber 12 first, so as to reduce the temperature in the heat dissipation chamber 12 and the outer surface of the door body 1 to avoid burns when the user touches the door body 1. The water in the heat dissipation chamber 12 then flows into the water tank assembly 300 through the water adding pipe 13, so that water can be added to the water tank assembly 300 through the handle 2 and the door body 1 without taking out the water tank assembly 300. The operation is simple and convenient, which improves the user's water adding experience. Even during the cooking process, the water tank assembly 300 can be added with water to realize a single long-term cooking of the cooking equipment, and it can also avoid water leakage caused by repeated removal and placement of the water tank assembly 300.

[0047] Furthermore, in the process of adding water to the water tank assembly 300, structures such as a water pump and a water valve are not required, which reduces costs and avoids the reliability of water inlet control of the water tank assembly 300 being affected by the failure of the water pump and the water valve as electrical components.

[0048] Furthermore, the door body 1 generally includes an outer door panel, a middle door panel and an inner door panel which are stacked. When the door body structure 100 is in the closed state, the inner door panel is located on the side of the middle door panel facing the cooking space, and the outer door panel is located on the side of the middle door panel facing away from the cooking space. The water adding chamber 11 and the heat dissipation chamber 12 are arranged between the middle door panel and the outer door panel, so that the temperature of the outer door panel can be reduced by the water in the heat dissipation chamber 12, thereby preventing the user from being scalded when touching the outer door panel. At the same time, the water in the heat dissipation chamber 12 can be prevented from reducing the temperature of the inner door panel and the cooking space, thereby preventing the cooking effect from being affected.

[0049] like Figures 2 to 3As shown, the door body 1 is also provided with a connecting pipe 14, and the two ends of the connecting pipe 14 are respectively connected to the bottom of the water adding chamber 11 and the top of the heat dissipation chamber 12. The door body structure 100 also includes a switch 3, and the switch 3 is used to control the opening and closing of the connecting pipe 14. When the temperature in the heat dissipation chamber 12 exceeds the preset maximum value, the switch 3 is controlled to open the connecting pipe 14, and part of the water in the water adding chamber 11 can flow into the heat dissipation chamber 12 through the connecting pipe 14 to reduce the temperature in the heat dissipation chamber 12 and the outer surface of the door body 1. It can be understood that when the temperature in the heat dissipation chamber 12 is low, the temperature in the cooking space is usually low. Therefore, when the temperature in the heat dissipation chamber 12 is lower than the preset minimum value, the switch 3 is controlled to close the connecting pipe 14, and the water in the water adding chamber 11 cannot flow into the heat dissipation chamber 12, so as to prevent the water in the heat dissipation chamber 12 from affecting the temperature rise rate in the cooking space. Among them, the preset maximum value and the preset minimum value can be set according to actual conditions, for example, the preset maximum value is 150°C, the preset minimum value is 100°C, etc., to ensure the cooking effect in the cooking space and avoid the user from being scalded when touching the door body 1. The embodiment of the present invention does not make specific restrictions here.

[0050] like Figure 3 to Figure 4 As shown, in one embodiment, the connecting pipe 14 includes a first connecting section 141 and a second connecting section 142, the first connecting section 141 extends along the height direction of the door body 1 (i.e., the Z-axis direction shown in the figure), and both ends are respectively connected to the outside and the heat dissipation chamber 12, the first connecting section 141 also includes a water inlet 1411 connected to the water adding chamber 11 and a water outlet 1412 connected to the second connecting section 142, and the end of the second connecting section 142 away from the water outlet 1412 is connected to the heat dissipation chamber 12; the switch member 3 includes a piston 31, and the piston 31 can be slidably arranged in the first connecting section 141 to connect or disconnect the water inlet 1411 with the water outlet 1412. When the temperature in the heat dissipation chamber 12 exceeds the preset maximum value, the air pressure at one end of the first connecting section 141 communicating with the heat dissipation chamber 12 increases, and can push the piston 31 to overcome its own gravity and slide upward in the first connecting section 141, so as to connect the water inlet 1411 with the water outlet 1412, and the water in the water supply chamber 11 can flow to the heat dissipation chamber 12 through the water inlet 1411, the water outlet 1412 and the second connecting section 142 in sequence, so as to reduce the temperature in the heat dissipation chamber 12. When the temperature in the heat dissipation chamber 12 is reduced to the preset minimum value, the air pressure at one end of the first connecting section 141 communicating with the heat dissipation chamber 12 decreases, and the piston 31 can slide downward in the first connecting section 141 under the action of its own gravity, so as to disconnect the water inlet 1411 from the water outlet 1412. In this way, the piston 31 can be automatically controlled to slide in the first connecting section 141 through the temperature change in the heat dissipation chamber 12 to achieve connection or disconnection between the water inlet 1411 and the water outlet 1412. There is no need to add additional temperature detection components, control valves and other structures. The structure is simple and the cost is low.

[0051] Specifically, the piston 31 includes a first sealing portion 311, a second sealing portion 313, and a connecting portion 312 connecting the first sealing portion 311 and the second sealing portion 313. When the piston 31 disconnects the water inlet 1411 from the water outlet 1412, the first sealing portion 311 seals the water inlet 1411, and the water in the water adding chamber 11 cannot enter the first connecting section 141 through the water inlet 1411. When the piston 31 opens the water inlet 1411 and the water outlet 1412, the first sealing portion 311, the connecting portion 312 and the second sealing portion 313 slide upward together in the first connecting section 141, and the first sealing portion 311 opens the water inlet 1411, and the water in the water adding chamber 11 enters the first connecting section 141 through the water inlet 1411. The second sealing portion 313 can prevent the water in the first connecting section 141 from entering the heat dissipation chamber 12 through the end of the first connecting section 141 that is connected to the heat dissipation chamber 12, so that the water entering the first connecting section 141 can enter the second connecting section 142 through the water outlet 1412.

[0052] Of course, in other embodiments, the switch element 3 may also include other structures such as a temperature detection element disposed in the heat dissipation cavity 12 and a control valve disposed in the connecting pipe 14. When the temperature detection element detects that the temperature in the heat dissipation cavity 12 exceeds a preset maximum value, the control valve opens to connect the connecting pipe 14; when the temperature detection element detects that the temperature in the heat dissipation cavity 12 drops to a preset minimum value, the control valve closes to disconnect the connecting pipe 14.

[0053] like Figure 3 As shown, the door structure 100 further includes a nozzle 4 disposed in the middle of the top of the heat dissipation cavity 12 and connected to the bottom of the water supply cavity 11. The nozzle 4 may be an atomizing nozzle or the like. Specifically, one end of the second connecting section 142 away from the first connecting section 141 is connected to the nozzle 4. The water in the second connecting section 142 can be uniformly sprayed into the heat dissipation cavity 12 in all directions through the nozzle 4 to enhance the cooling effect.

[0054] like Figure 3 to Figure 4 As shown, the door structure 100 also includes a water retaining member 5 disposed in the heat dissipation cavity 12 and located at the bottom of the nozzle 4. The water retaining member 5 extends along the width direction of the door body 1 (i.e., the X-axis direction shown in the figure), and the water retaining member 5 is provided with a plurality of water outlet holes 51 arranged at intervals. The water sprayed from the nozzle 4 falls on the water retaining member 5 and flows downward uniformly through the plurality of water outlet holes 51 on the water retaining member 5, thereby further improving the uniformity of the water in the heat dissipation cavity 12 and enhancing the cooling effect. Preferably, the plurality of water outlet holes 51 are evenly spaced along the width direction of the door body 1.

[0055] like Figure 1 to Figure 2As shown, the door body 1 includes a window area opposite to the heat dissipation cavity 12, and the inner wall of the heat dissipation cavity 12 is provided with a hydrophobic layer. At least the portion of the door body 1 in the window area is a transparent structure, and the user can observe the cooking conditions inside the cooking space through the window area. The hydrophobic layer allows the water droplets hanging on the inner wall of the heat dissipation cavity 12 to quickly flow to the bottom of the heat dissipation cavity 12, and flow to the water tank assembly 300 through the water supply pipe 13, so as to prevent the water droplets from affecting the user's observation of the cooking space through the window area, thereby ensuring the visual effect of the window area. In addition, cooling the heat dissipation cavity 12 by water can also prevent the inner wall of the heat dissipation cavity 12 from fogging, thereby ensuring the visual effect of the window area.

[0056] like Figure 3 to Figure 4 As shown, the door structure 100 further includes a partition 6 protruding from the bottom wall of the water-adding chamber 11, and the partition 6 divides the water-adding chamber 11 into a first area 111 and a second area 112; a first outlet 113 communicating with the water-adding pipeline 13 is provided at the bottom of the first area 111, and a second outlet 114 communicating with the heat-dissipating chamber 12 is provided at the bottom of the second area 112, and a water-adding port 21 is provided in the second area 112. The volume of the second area 112 is preferably much larger than the volume of the first area 111. When water is added to the water-adding chamber 11 through the water-adding port 21 on the handle 2, the water first falls into the second area 112, and when the switch 3 closes the connecting pipeline 14, the water level in the second area 112 will gradually rise until the water level in the second area 112 is submerged by the partition 6, and the water in the second area 112 will enter the first area 111, and the water in the first area 111 will flow into the water tank assembly 300 through the first outlet 113 and the water-adding pipeline 13. When the temperature in the heat dissipation cavity 12 exceeds the preset maximum value, the control switch 3 opens the connecting pipe 14, and the water in the second area 112 can flow into the heat dissipation cavity 12 through the connecting pipe 14. In this way, it can be ensured that there is enough water in the second area 112 to dissipate the heat of the heat dissipation cavity 12 during the cooking process, and the user does not need to add water repeatedly, thereby improving the user experience.

[0057] Specifically, the second outlet 114 is connected to the water inlet 1411 of the first connecting section 141. When the first sealing portion 311 connects the water inlet 1411 and the second outlet 114, water in the second area 112 enters the first connecting section 141 through the water inlet 1411 and the second outlet 114; when the first sealing portion 311 disconnects the water inlet 1411 and the second outlet 114, water in the second area 112 cannot enter the first connecting section 141 through the water inlet 1411 and the second outlet 114.

[0058] Furthermore, the water adding pipeline 13 includes a first water adding section 131 and a second water adding section 132. One end of the first water adding section 131 is in communication with the first outlet 113. When the door structure 100 is in the closed state, the other end of the first water adding section 131 is in communication with the water tank assembly 300. One end of the second water adding section 132 is in communication with the bottom of the heat dissipation cavity 12, and the other end is in communication with the first water adding section 131. The water in the heat dissipation cavity 12 can flow into the first water adding section 131 through the second water adding section 132, and flow into the water tank assembly 300 together with the water in the first water adding section 131.

[0059] like Figures 5 to 7 As shown, the door structure 100 also includes a cover assembly 7 that can be opened and closed at the water inlet 21. The cover assembly 7 can prevent foreign dust and other impurities from falling into the water adding chamber 11 or the heat dissipation chamber 12 through the water inlet 21, which makes it difficult to clean or affects cooking. Specifically, the handle 2 is provided with a water adding tank, and the water adding tank is provided with an upward water adding port 21. The door body 1 is also provided with a water inlet pipe 15, one end of the water inlet pipe 15 is connected to the bottom of a side wall of the water adding tank facing the door body 1, and the other end of the water inlet pipe 15 is connected to the top of the second area 112. The bottom wall of the water adding tank can be tilted toward the water inlet pipe 15 so that the water in the water adding tank can flow into the water inlet pipe 15.

[0060] like Figure 6 to Figure 7 As shown, the cover plate assembly 7 includes a cover plate 71 and a torsion spring 72. One end of the cover plate 71 is rotatably connected to the handle 2, and the other end is detachably engaged with the handle 2. The two torsion arms of the torsion spring 72 are respectively connected to the cover plate 71 and the handle 2. The cover plate assembly 7 also includes a fastener 73 provided on the handle 2. One end of the cover plate 71 is detachably engaged with the fastener 73, and the torsion spring 72 is in a torsion state when the cover plate 71 is engaged with the fastener 73. In this way, the structure of the cover plate assembly 7 is simple and convenient for users to control. When it is necessary to add water to the water inlet 21, the cover plate 71 is pressed so that the cover plate 71 is disengaged from the fastener 73, and the cover plate 71 is rotated and opened relative to the handle 2 under the action of the torsion force of the torsion spring 72; after the water is added, the cover plate 71 is controlled to rotate in the opposite direction relative to the handle 2 to close and engage with the fastener 73, and the torsion spring 72 is twisted.

[0061] like Figure 7 As shown, the cross-sectional area of ​​the water inlet 21 is greater than or equal to 50 cm 2 In this way, when the user adds water to the water inlet 21 , the water can quickly flow into the water adding chamber 11 , thereby improving the water adding efficiency and also preventing the water from overflowing from the water inlet 21 .

[0062] like Figure 1 and Figure 8As shown, an embodiment of the present invention further provides a cooking device, including a box body 200, a water tank assembly 300 and the above-mentioned door structure 100, wherein: the water tank assembly 300 is arranged at the bottom of the box body 200; the door structure 100 can be opened and closed and arranged on the box body 200. Specifically, the cooking device can be a steamer, a steam-bake-in-one machine, etc. The water tank assembly 300 is arranged at the bottom of the box body 200, and the original space at the bottom of the box body 200 can be used to make the volume of the water tank assembly 300 larger, for example, more than 2L, to further meet the single long-term cooking needs, and will not increase the overall volume of the cooking device.

[0063] like Figure 1 and Figure 8 As shown, the cooking device further includes a housing (not shown) and a cover 400. The box body 200 and the water tank assembly 300 are both disposed in the housing. The cover 400 is openably disposed in the housing and is located at the bottom of the door structure 100. In the closed state, the cover 400 can shield other structures in the cooking device such as the water tank assembly 300 to prevent the water tank assembly 300 and other structures from being exposed, so as to ensure the overall appearance of the cooking device is neat; when the water tank assembly 300 needs to be taken out, the cover 400 can be flipped open.

[0064] like Figures 9 and 10 As shown, the water tank assembly 300 includes a water tank body 301 and a water level detection assembly 302 disposed in the water tank body 301. Specifically, the water level detection assembly 302 includes a float 3021 and a water level detection plate 3022. The float 3021 is disposed in the water tank body 301 and can rise and fall together with the water level in the water tank body 301. The water level detection plate 3022 can be electrically connected to the control assembly of the cooking device. The water level detection plate 3022 is used to detect the position of the float 3021 and feed back to the control assembly. In this way, the water level detection assembly 302 can facilitate the user to understand the water level in the water tank body 301. When the water level detection assembly 302 detects that the water level in the water tank body 301 is lower than the preset minimum water level, the control assembly can be used to remind the user to add water; when the water level detection assembly 302 detects that the water level in the water tank body 301 reaches the preset maximum water level, the control assembly can be used to remind the user to stop adding water.

[0065] like Fig. 9 As shown, a water inlet 3011 is provided on the top of the water tank body 301 , and when the door structure 100 is in the closed state, an end of the first water adding section 131 away from the first outlet 113 is connected to the water inlet 3011 .

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0067] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
