Description

Technical Field

[0001] The invention relates to the field of ovens, and in particular to a novel oven. Background Art

[0002] As one of the indispensable accessories in the electric oven, the baking tray is heated in the electric oven. Due to the thermal conductivity of the material, the temperature of the baking tray rises rapidly due to the influence of heat radiation and convection heating. Due to the high temperature of the baking tray, there is a certain safety risk when taking out the baking tray. The chef often needs to wear heat-insulating gloves when taking out the baking tray to prevent burns.

[0003] However, in the hotel kitchen, there are often a limited number of electric ovens. When encountering peak dining times (such as lunch or dinner time), cooking work is usually in a high-intensity operation state. The kitchen needs to quickly complete the processing and preparation of a large number of dishes to meet the needs of customers. The chef needs to operate the oven frequently, such as briefly opening the door during the baking process to add or replace new ingredients in time. In this case, the kitchen staff needs to efficiently manage the cooking process. Therefore, the kitchen staff is required to take out the baked food in the oven in time and send in the next ingredient to be baked as soon as possible. In this process, the chef needs to wear heat-insulating gloves before taking out the baking tray, and the chef needs to take off the heat-insulating gloves for subsequent cooking of the ingredients. The whole process is cumbersome and affects work efficiency. Therefore, it is necessary to improve the existing oven to ensure that when the food is baked, the chef can directly take the baking tray out of the electric oven. Summary of the invention

[0004] The purpose of the present application is to provide a new type of oven to solve the problem that the temperature of the baking tray in the oven is high after baking in the existing oven, which makes it troublesome to take out the baking tray and affects the work efficiency. The specific technical solution is as follows:

[0005] A novel oven comprises an oven body, a baking tray and a cooling device, wherein the oven body is provided with a heating furnace cavity and is used for placing and heating the baking tray, the cooling device is arranged in the oven body, the cooling device comprises a circulating cooler and an infusion tube connected thereto, the infusion tube is connected with an elastic interface, the elastic interface is arranged on the inner wall of the heating furnace cavity, grabbing ear plates are provided on both sides of the baking tray, a pipeline is provided inside the grabbing ear plates, a plug-in groove is provided on the end face of the grabbing ear plate, an inlet and an outlet of the pipeline are respectively connected to two opposite side surfaces of the plug-in groove, and the plug-in groove is detachably connected to the elastic interface.

[0006] As one of the improvements of the above technical solution, a partition is provided in the middle of the infusion tube to divide the infusion tube into a first delivery tube and a second delivery tube, and a first opening and a second opening are provided on both sides of the end of the infusion tube, respectively, the first opening is connected to the first delivery tube, and the second opening is connected to the second delivery tube.

[0007] As one of the improvements of the above technical solution, the elastic interface includes a silicone sleeve, which is sleeved on the end of the infusion tube, and is provided with a third opening and a fourth opening, the first opening is connected to the third opening, and the second opening is connected to the fourth opening.

[0008] As one of the improvements of the above technical solution, an opening is provided in the middle of the grabbing ear plate, and the infusion tube is arranged around the opening.

[0009] As one of the improvements of the above technical solution, the infusion tube is arranged obliquely, and the inlet and outlet of the infusion tube are at the bottom.

[0010] As one of the improvements of the above technical solution, the end surface of the silicone sleeve is provided with an inner concave surface.

[0011] As one of the improvements of the above technical solution, a bracket is provided in the heating furnace cavity for placing the baking tray, the bracket is provided with a raised guide rail, and a slide groove is provided on the bottom surface of the baking tray, and the slide groove is used to accommodate the guide rail.

[0012] As one of the improvements of the above technical solution, the first delivery pipe is arranged on the outside of the second delivery pipe, and the circulating cooler is used to deliver liquid to the first delivery pipe. The liquid flows through the pipeline and flows back to the circulating cooler along the second delivery pipe.

[0013] The beneficial effects of the present application are as follows: by setting up a cooling device, a circulating cooler transports liquid, which can be a liquid at room temperature or low temperature, and enters the pipeline through an infusion tube. The liquid entering the pipeline flows around the pipeline and exchanges heat with the grabbing ear plate, and finally returns to the infusion tube. The liquid and the grabbing ear plate are used to exchange heat and then cool the grabbing ear plate. In this way, after the oven completes baking, the grabbing ear plate can be quickly cooled to facilitate the chef to take it out. Since the elastic interface or the silicone sleeve is made of silicone material, when the oven is heated, the temperature inside the oven will rise. In this high-temperature environment, the silicone sleeve made of silicone material will expand due to heat and strengthen the sealing effect between the elastic interface and the plug-in slot. Affected by the expansion of the silicone sleeve, the connection between the elastic interface and the plug-in slot is also tighter and not easy to separate. After the heating is completed, as the circulating cooler continuously transports new liquid, the liquid will also complete heat exchange with the silicone sleeve, thereby cooling the silicone sleeve to facilitate the separation of the elastic interface from the plug-in slot.

[0014] Additional aspects and advantages of the present invention will be given in part in the description below, and in part will become apparent from the description below, or will be understood through the practice of the present invention. Of course, it is not necessary to achieve all of the advantages described above at the same time to implement any product or method of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In the existing oven, the temperature of the baking tray in the oven is high after baking, which makes it difficult to remove the baking tray and affects work efficiency. Figure 1-9 The present invention provides an embodiment to solve the above problem, specifically comprising an oven body 1, a baking tray 2 and a cooling device 3, wherein the oven body 1 is provided with a heating furnace cavity 11 and is used to place and heat the baking tray 2, the cooling device 3 is arranged in the oven body 1, the cooling device 3 comprises a circulating cooler 31 and an infusion pipe 32 connected thereto, the infusion pipe 32 is connected with an elastic interface 33, the elastic interface 33 is arranged on the inner wall of the heating furnace cavity 11, grabbing ear plates 21 are provided on both sides of the baking tray 2, a pipe 22 is provided inside the grabbing ear plates 21, a plug-in groove 23 is provided on the end face of the grabbing ear plates 21, the inlet and outlet of the pipe 22 are respectively connected to the two opposite sides of the plug-in groove 23, and the plug-in groove 23 is detachably connected to the elastic interface 33;

[0029] When the baking tray 2 is placed in the heating furnace cavity 11 or when the baking tray 2 is pushed into the heating furnace cavity 11, the grabbing ear plate 21 on the baking tray 2 will gradually approach the inner wall of the heating furnace cavity 11. After reaching the predetermined position, the elastic interface 33 will be inserted into the plug-in slot 23. By setting the cooling device 3, the circulating cooler 31 transports liquid, which can be a liquid at room temperature or low temperature, and enters the pipeline 22 through the infusion tube 32. The liquid entering the pipeline 22 flows around the pipeline 22 and exchanges heat with the grabbing ear plate 21, and finally returns to the infusion tube 32. The liquid is used to exchange heat with the grabbing ear plate 21 to achieve cooling of the grabbing ear plate 21. In this way, after the oven finishes baking, the grabbing ear plate 21 can be quickly cooled so that the chef can take it out.

[0030] In order to prevent the liquid transported by the circulating cooler 31 from mixing with the liquid after heat exchange, preferably, a partition is provided in the middle of the infusion tube 32 to divide the infusion tube 32 into a first delivery tube 3311 and a second delivery tube 3312, and a first opening and a second opening are provided on both sides of the end of the infusion tube 32, respectively, the first opening is connected to the first delivery tube 3311, and the second opening is connected to the second delivery tube 3312, that is, the new liquid transported by the circulating cooler 31 is separated from the liquid after heat exchange. The specific principle is: the liquid transported by the circulating cooler 31 or the cooled liquid flows through the first delivery tube 3311 and enters the pipeline 22 from the inlet of the pipeline 22. After the liquid surrounds the pipeline 22 once, it flows out from the outlet of the pipeline 22 and flows into the second delivery tube 3312. After the liquid flows through the second delivery tube 3312, it flows back to the circulating cooler 31, thereby completing the cycle.

[0031] Since the elastic interface 33 is only plugged into the plug-in slot 23, the sealing effect of the plug-in alone is poor. When the liquid transported by the circulating cooler 31 passes through the elastic interface 33 and the plug-in slot 23, there is a risk of overflow. To this end, the present invention provides an embodiment to solve this problem. Specifically, the elastic interface 33 includes a silicone sleeve 331, and the silicone sleeve 331 is sleeved on the end of the infusion tube 32. The silicone sleeve 331 is provided with a third opening 332 and a fourth opening 333. The first opening is connected to the third opening 332, and the second opening is connected to the fourth opening 333.

[0032] It can be understood that the present invention starts the circulating cooler 31 to transport liquid only after heating. Since the elastic interface 33 or the silicone sleeve 331 is made of silicone material, when the oven is heated, the temperature inside the oven will rise. In this high-temperature environment, the silicone sleeve 331 made of silicone material will expand due to the heat and strengthen the sealing effect between the elastic interface 33 and the plug-in slot 23. Affected by the expansion of the silicone sleeve 331, the connection between the elastic interface 33 and the plug-in slot 23 is also tighter and not easy to separate. After the heating is completed, as the circulating cooler 31 continuously transports new liquid, the liquid will also complete heat exchange with the silicone sleeve 331, thereby cooling the silicone sleeve 331 to facilitate the separation of the elastic interface 33 from the plug-in slot 23.

[0033] Regarding the circulating cooler 31, the circulating cooler 31 includes a water storage tank, a fan, a circulating water pump, etc. Such circulating cooling systems are well known to those skilled in the art.

[0034] Preferably, an opening is provided in the middle of the grabbing ear plate 21, and the infusion tube 32 is arranged around the opening. The opening is provided to facilitate the chef to grab the oven. The infusion tube 32 is inclined, and the inlet and outlet of the infusion tube 32 are at the bottom. By tilting the infusion tube 32, it is ensured that after the circulating cooler 31 stops, no liquid remains in the infusion tube 32. It can be understood that the liquid in the infusion tube 32 will automatically flow along the inner wall of the infusion tube 32 to the outlet or inlet of the infusion tube 32 under the influence of gravity.

[0035] In order to reduce the heat taken away from the heating furnace cavity 11 by the liquid during the heating process of the heating furnace cavity 11, the present invention also provides an embodiment. Specifically, the preset heating time of the heating furnace cavity 11 is set to T0. Only when the heating time reaches T0, the circulating cooler 31 is started. The water pressure P of the liquid transported by the circulating cooler 31 is positively correlated with T0, that is, as T0 increases, P will also increase. It can be understood that in the above-mentioned heat exchange process, an increase in the liquid flow rate will usually improve the heat exchange efficiency. The longer the heating time, the higher the temperature of the grabbing ear plate 21. Therefore, the flow rate of the liquid can be controlled by controlling the water pressure P to control the heat exchange efficiency.

[0036] In some embodiments, the first delivery pipe 3311 is arranged on the outside of the second delivery pipe 3312, and the circulating cooler 31 is used to deliver liquid to the first delivery pipe 3311. The liquid flows through the pipeline 22 and flows back to the circulating cooler 31 along the second delivery pipe 3312. It can be understood that the purpose of providing an opening in the middle of the grabbing ear plate 21 is to facilitate the operator to hold it. Generally, the operator's hand is usually held on the outside of the grabbing ear plate 21. By arranging the first delivery pipe 3311 on the outside of the second delivery pipe 3312, it is ensured that the liquid delivered by the circulating cooler 31 or the cooled liquid is firstly dissipated to the main holding part, that is, the outside of the grabbing ear plate 21. When the heating furnace chamber 11 is heated, the outside of the grabbing ear plate 21 reaches a temperature suitable for holding.

[0037] In some embodiments, the end surface of the silicone sleeve 331 is provided with an inner concave surface, and a suction cup can be formed by providing the inner concave surface, so as to be adsorbed in the plug-in slot 23 .

[0038] In order to ensure that the elastic interface 33 and the plug-in slot 23 can be smoothly docked, a bracket is provided in the heating furnace cavity 11 for placing the baking tray 2, the bracket is provided with a raised guide rail, and a slide groove is provided on the bottom surface of the baking tray 2, and the slide groove is used to accommodate the guide rail. Accurate alignment can be achieved by setting the guide rail in conjunction with the slide groove.

[0039] In some embodiments, a plurality of limit blocks 111 arranged side by side and at intervals are provided on the inner wall of the heating furnace cavity 11 of the oven body 1, and a limit groove is formed between every two limit blocks 111 to accommodate the grabbing ear plate 21. Preferably, a heat insulating layer 112 is connected to the inner wall of the limit groove. When the grabbing ear plate 21 enters the limit groove, the heat insulating layer 112 can minimize the influence of the high temperature gas in the subsequent heating furnace cavity 11 on the grabbing ear plate 21. In this way, the temperature of the grabbing ear plate 21 heated by the heating furnace cavity 11 is limited to a certain extent, so as to avoid the infusion tube 32 being broken due to the influence of thermal expansion and contraction due to the large temperature difference.

[0040] The above technical solution will place the grabbing ear plate 21 in the limiting groove, so that the operator cannot directly touch the grabbing ear plate 21. To this end, the present invention also provides an embodiment. Specifically, the front end surface of the baking tray 2 is connected with a handle 24, and an insulating belt 25 is provided between the handle 24 and the baking tray 2. The insulating belt 25 is provided to block the heat that may be transferred from the baking tray 2 to prevent the handle 24 from heating up. Preferably, an opening is reserved on the door connected to the oven body 1 to expose the handle 24 outward, or the door is also equipped with a similar limiting groove structure to accommodate the handle 24.

[0041] When the oven body 1 has finished heating, the operator needs to hold the handle 24 first. It should be noted that at this time, the operator only touches the handle 24 but does not touch the baking tray 2. After holding the handle 24, the operator pulls the baking tray 2 outward, and the grabbing ear plates 21 on both sides of the baking tray 2 will slide out of the limiting grooves. At this time, the operator can hold the grabbing ear plates 21 on both sides of the baking tray 2 with both hands to take out the baking tray 2.

[0042] It should be noted that the terms "first", "second", etc. in this document are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
