Description

Technical Field

[0001] This application relates to a water evaporation device and an oven including the water evaporation device. Background Technology

[0002] Steam and steam-assisted cooking technologies are becoming increasingly popular in homes due to their beneficial effects on baking. Consequently, more and more household appliances equipped with steam-assisted cooking functions have appeared on the market in recent years. A humid environment, i.e., steam in the air, promotes heat transfer, resulting in a golden-brown surface on food. This effect is particularly noticeable in the early stages of baking. Currently, there are two main types of steam-assisted cooking appliances on the market. The first type uses electric steam generators to produce steam. This technology ensures a fully saturated cooking environment for steam cooking, but it also functions as a steam-assisted cooking technology (increasing steam but not achieving a fully saturated environment). Since baking does not require a fully saturated environment, this type of appliance is expensive for most users. Therefore, the second type of appliance on the market uses other steam generation methods and does not rely on electronic components.

[0003] When operating an oven, a certain amount of water can be vaporized, distributed, and diffused into the heating chamber in order to improve cooking by using hot air containing a certain amount of vaporized air, which affects the cooking performance.

[0004] In common ovens, a steam function can be used, allowing dishes or containers to be placed at the bottom of the heating chamber or near a fan with a separate heating element to heat the water in the dishes or containers so that it is vaporized into steam during cooking. These containers are typically not removable by the end user and may have complex piping arrangements for supplying water to the containers.

[0005] It is well known that higher humidity levels during baking improve heat transfer to the surface of food, resulting in a crispy crust and a juicy interior. This effect is most beneficial for baked goods and pastries. However, it also helps create a crispy crust for other types of food. Some studies suggest that humidity can improve heat transfer efficiency in the initial stages of the baking process (approximately the first 30 minutes).

[0006] A major technical challenge that urgently needs to be addressed is how to create a humid environment during baking without using a separate steam generator; that is, to find a cost-effective solution that can help create a humid environment during baking. Therefore, the purpose of this application is to improve the cooking effect of a basic baking system, rather than to create a fully saturated cooking environment (steam cooking).

[0007] Pouring water to the bottom of the oven cavity is the most popular technology on the market. It uses a bottom heater to evaporate water, which is either poured directly to the bottom by the user or into a water tank on the control panel. Then, during baking, the system releases the water to the bottom to evaporate. This solution makes water evaporate easily and creates humidity because the bottom heater is placed directly below the water, eliminating the need for forced air circulation to disperse steam around the cavity. On the other hand, the enamel can experience some problems during water evaporation because the bottom heater is located outside the cavity, creating a significant temperature difference during heating. Subsequent temperature deformation can lead to enamel cracking and other challenges. Most importantly, after the water evaporates, limestone can remain on the bottom of the oven, making it difficult to clean.

[0008] In addition, water can be filled into an evaporation tray placed at the bottom of the oven cavity, a technique somewhat similar to those mentioned earlier. However, the water is poured into a shallow evaporation tray before being placed at the bottom of the oven to avoid limestone buildup. On the other hand, evaporating the same amount of water takes significantly longer because of the additional material between the water and the bottom. This solution cannot automatically add water and requires user intervention.

[0009] In addition, evaporation trays can be mounted on rails or other locations where water can be poured into a special evaporation tray, which is then placed in different positions (but not on the bottom of the oven to avoid enamel problems). Evaporation trays can come in different shapes depending on their intended placement. Some trays are placed on wire racks, while others are suspended on linear or telescopic rails. The first drawback of this solution is that, because the evaporation tray occupies space, at least one layer of rails cannot be used for cooking. This reduces the usable volume during cooking and also affects temperature uniformity during baking. The second drawback is the evaporation time. Because the tray is placed far from the heater, evaporating water takes the longest time.

[0010] EP3372900A1 describes a water container and supply channel for generating steam. Summary of the Invention

[0011] The purpose of this application is to improve the way of performing steam generation functions and to provide a water evaporation device that can be easily installed in an oven, with an improved and simplified way of generating vaporized water for cooking in the oven.

[0012] The technical solution in the independent claim solves this problem.

[0013] This application relates to the water evaporation apparatus according to claim 1 and the oven according to claim 16.

[0014] The preferred embodiments are the technical solutions described in the dependent claims.

[0015] The water evaporation device for a cooking appliance according to this application includes: a support member attachable to a heating portion in a heating chamber of the cooking appliance, the support member including an inlet for a tray unit and a sliding portion; and a tray unit into which water for evaporation in the heating chamber can be filled, wherein the tray unit is configured to be attachable to the support member, and wherein the tray unit has a bowl-shaped portion for receiving the water; wherein the tray unit is attachable to the support member such that the bowl-shaped portion can be positioned below an outer main branch of a heating coil of the heating portion, thereby extending below the outer main branch of the heating coil, such that the water in the bowl-shaped portion can be heated by the outer main branch of the heating coil to vaporize the water, and wherein, after being inserted into the support member through the inlet, the tray unit can be placed on the sliding portion and slide along the sliding portion.

[0016] The inlet can form a cage, and the rods can be metal wire or a material capable of withstanding high-temperature cooking. The support structure holds the tray unit at a predetermined optimal distance below the heating element to heat and vaporize the water, allowing for easy and rapid evaporation. Due to the streamlined structure of the support, its impact on heater radiation is minimal when the tray unit is not present. The tray unit can be made of sheet metal (stainless steel) or 3D printed.

[0017] The tray unit can also be completely removed from the oven cavity for cleaning and / or storage, thus simplifying operations.

[0018] The tray unit is configured to be attached to the support, so that it can be placed on the rod of the support in a resting and sliding manner.

[0019] The heating cavity describes any internal space within the oven where air can be heated or radiation provided for cooking. The bowl-shaped portion includes a horizontally oriented cavity in which water can be received for vaporization, specifically heated by radiation and / or hot air from the heating section until it is partially or completely vaporized. The bowl-shaped portion may also have a circumferential edge that can surround the bowl-shaped portion.

[0020] Water evaporation devices can be used in multi-functional ovens, such as ovens that provide steam and / or pyrolysis functions, for freestanding cookers or freestanding (countertop) ovens, and all combinations thereof.

[0021] According to a further embodiment of the water evaporation device, the tray unit has a first end and a second end along the longitudinal extension direction of the tray unit, and a circumferential edge forming the upper sidewall of the bowl-shaped portion, wherein the bowl-shaped portion is located between the first end and the second end along the longitudinal extension direction, and wherein the tray unit has a retaining portion at the first end or the second end to allow a user to hold the tray unit when attaching and / or detaching (sliding or otherwise moving) the tray unit to the support. The tray unit may be symmetrically arranged with respect to the longitudinal extension direction, such that a similar or identical retaining portion may also exist at the second end.

[0022] Similar to the first and second ends, a region can also be defined near the corresponding longitudinal end, extending a specific small distance from the longitudinal end, such as 5 mm. The circumferential edge can represent the (transverse and other) sidewalls of the bowl-shaped portion.

[0023] The longitudinal extension direction of the bowl-shaped part and the longitudinal extension direction of the tray unit can be at least partially parallel to a portion of the heating coil of the heating part.

[0024] The retaining part can be a region of the plate or the pallet unit itself (manufactured separately or as a single unit), which can be bent at an angle or perpendicular to the longitudinal extension direction so that the user can hold it and push or pull the pallet unit along the sliding part. If the pallet unit is in use and is hot, the user should use heat-insulating devices such as gloves.

[0025] Regarding the inlet, there are no general limitations on its possible shape, and several possible embodiments exist. While the main part of this specification considers a cage-like structure for the inlet, with some possible annular portions on the left and / or right sides, the inlet is not limited to this. In other words, the inlet may also be, for example, a straight extension of the sliding portion (on its left and right sides) or have other shapes.

[0026] According to a further embodiment of the water evaporation device, the tray unit includes at least one first left sliding protrusion and at least one second left sliding protrusion, both of which are flat portions and extend laterally outward from the circumferential edge on the same lateral first side of the tray unit. The first left sliding protrusion is located at a first distance from the first end of the tray unit, and the second left sliding protrusion is located at a second distance from the first end of the tray unit, wherein the second distance is greater than the first distance. Furthermore, the tray unit also includes at least one first right sliding protrusion and at least one second right sliding protrusion, both of which are flat portions and extend laterally outward from the circumferential edge on the same lateral second side of the tray unit, with the lateral second side of the tray unit opposite to the lateral first side of the tray unit. The first right sliding protrusion is located at a third distance from the first end of the tray unit, and the second right sliding protrusion is located at a fourth distance from the first end of the tray unit, wherein the fourth distance is greater than the third distance.

[0027] According to a further embodiment of the water evaporation device, the sliding portion has a left branch and a right branch formed by a rod, the left branch and the right branch extending parallel to each other from the inlet portion, the distance between them being greater than the width of the tray unit, and the first left sliding protrusion and the second left sliding protrusion being able to slide along the left branch, the first right sliding protrusion and the second right sliding protrusion being able to slide along the right branch, and / or, wherein the left branch and the right branch are parallel to the outer main branch of the heating coil. In this way, the installation method of the support can be improved, and the proportion of the heating coil exposed to water can be maximized.

[0028] According to a further embodiment of the water evaporation device, the first left sliding protrusion or the first right sliding protrusion has a stop shape or a locking shape for stopping the tray unit at the rod portion of the inlet when the tray unit slides outward along the sliding portion of the support. The stop shape / structure and / or locking shape / structure clearly define the refilling location. The stop shape / structure and / or locking shape / structure can also be provided on one of the second (left and / or right) sliding protrusions. In this case, the support can provide a corresponding vertical rod portion where a specific stop shape / structure and / or locking shape / structure can abut against and prevent longitudinal sliding toward the inlet.

[0029] According to a further embodiment of the water evaporation device, the first left sliding protrusion and / or the second left sliding protrusion and / or the first right sliding protrusion and / or the second right sliding protrusion have at least a partially flat sled shape, the sled shape having a protrusion on its underside, the protrusion being perpendicular to the circumferential edge and extending along a first lateral direction or a second lateral direction, so that the tray unit slides along the sliding portion via the protrusion.

[0030] According to a further embodiment of the water evaporation device, the bottom of the bowl-shaped portion includes a reinforcing structure as a ridge, the reinforcing structure extending along the longitudinal extension direction or perpendicular to the longitudinal extension direction.

[0031] According to a further embodiment of the water evaporation device, the bowl-shaped portion includes a maximum liquid level mark located inside the circumferential edge and / or an inner bowl bottom region, the inner bowl bottom region forming a further bowl with a bottom volume at the bottom of the bowl-shaped portion. This further bowl has the greatest impact (positive impact) on stiffness and is actually more helpful in maintaining the stability of the bowl-shaped structure than potential reinforcement at the bottom of the tray unit.

[0032] According to a further embodiment of the water evaporation device, the support is made of a single bent rod or multiple rods.

[0033] The rod can be linear; by bending a single rod to form the entire support, the workload and cost can be reduced, and the stability of the support can be improved.

[0034] According to a further embodiment of the water evaporation device, the inlet has a cage-like structure formed by a bent rod. When the tray unit is inserted through the cage-like structure of the inlet at a predetermined first lateral distance from the first lateral side of the tray unit and a predetermined second lateral distance from the second lateral side of the tray unit, the cage-like structure can at least partially laterally surround the first end of the tray unit.

[0035] According to a further embodiment of the water evaporation device, the first left sliding protrusion or the first right sliding protrusion has a stop shape or a locking shape for stopping the tray unit at the cage-like structure at the inlet when the tray unit slides outward along the sliding portion of the support member. The first left sliding protrusion or the first right sliding protrusion has a range of the stop shape or the locking shape in the lateral direction. If the first left sliding protrusion has the stop shape or the locking shape, the range is greater than the preset first lateral distance. Or, if the first right sliding protrusion has the stop shape or the locking shape, the range is greater than the preset second lateral distance.

[0036] According to a further embodiment of the water evaporation device, the first left sliding protrusion or the first right sliding protrusion having a stop shape or a locking shape for stopping the tray unit can overcome the stop at the cage structure by moving the tray unit in a lateral direction in the plane and toward the corresponding opposite lateral side of the cage structure, rather than the lateral side to which the first left sliding protrusion or the first right sliding protrusion having the stop shape or the locking shape extends.

[0037] Simply rotate the tray unit in the plane and pull it to completely remove the tray unit from the support.

[0038] According to a further embodiment of the water evaporation device, the cage-like structure can be installed on the outer main branch of the heating coil.

[0039] According to a further embodiment of the water evaporation device, the support includes a rear end portion, at which the bending rod bends upward from the sliding height of the sliding portion to form a rear vertical stop for the second left sliding protrusion and / or the first right sliding protrusion and / or the second right sliding protrusion of the tray unit, and above the rear vertical stop, the bending rod bends horizontally, and the bending rod may be attached to the outer main branch of the heating coil and / or another branch of the heating coil.

[0040] The rear end can keep the support in a horizontal plane and stop the tray unit in a preset rear position, which is the operating position where water is maximally exposed to the outer main branch of the heating coil.

[0041] According to a further embodiment of the water evaporation device, the tray unit can be inserted into the support member through the inlet and then slid to an operating position, such that the tray unit is located below the outer main branch of the heating coil of the heating unit, extending to the entire transverse outer main branch of the heating coil below, thereby sliding the tray unit to a service position, where water can be filled into the bowl-shaped portion, and the first left sliding protrusion or the first right sliding protrusion abuts against a stop shape or a locking shape, the stop shape or the locking shape being used to stop the tray unit at the rod portion of the inlet when the tray unit is slid outward along the sliding portion of the support member.

[0042] An oven for cooking according to this application includes: a heating cavity; a heating section located within the heating cavity, wherein the heating section has at least one heating coil having an external main branch, the at least one heating coil extending in the top region of the heating cavity; and a water evaporation device as described above, wherein the support is at least attached to the external main branch of the heating coil.

[0043] The oven can be any type of oven, such as a microwave oven, pyrolysis oven, steam oven, or combination oven.

[0044] According to a further embodiment of the water evaporation device, the inlet portion of the support faces the opening of the heating chamber and the door of the heating chamber, wherein the support is attached to at least one of the heating coils on the right, middle or left side of the heating chamber.

[0045] The support may have a rod or a line or any other component, which may have a circular cross-section or a similar circular cross-section or a square cross-section or a rectangular cross-section.

[0046] The pallet unit may also include other suitable materials, such as those made by die casting, that can be heated and withstand temperatures above 500°C, and are corrosion resistant.

[0047] By using an oven, a simple and inexpensive steam-assisted cooking function can be provided, especially for low-priced ovens, which are easy to clean and offer better cooking performance. Using a water evaporator inside the oven allows steam to be added to the heating element during the baking cycle or cooking process, representing a cheap and quick solution for providing steam. Therefore, steam can also be provided to ovens and cooking appliances that were not initially designed as steam ovens or combined steam ovens via a water evaporator. Adding steam to support baking functions can increase the trend of this simple cooking method and improve the cooking results for most food types, such as bread baking, meat baking, and vegetable cooking. The oven described in this application can be easily implemented, improving the quality of food preparation with minimal investment and cost, and can operate throughout the product lifecycle without significant quality problems. It can reduce costs, improve cooking results, reduce or even prevent scale buildup in the heating chamber, and does not require an additional steam heater. The tray unit can be cleaned from outside the oven, increasing the ease of cleaning.

[0048] The heating element may have one or more coils, for example, one for conventionally heating air, and others for grilling or infrared heating. The oven may be a multi-functional oven or a pyrolysis oven. The oven may have a fan to distribute vaporized water within the heating chamber.

[0049] The steam supply function can only be activated when the corresponding oven heating element is in an activated state. This function can be activated and controlled by the control unit, for example, by running different programs (temperature, water supply, steam volume). In principle, the heating element can perform its main function while heating the water used for vaporization. That is to say, in addition to heating the water in the tray unit, the heating chamber can also provide heat or radiation to the food.

[0050] When the tray unit is attached to the support, it can be concealed within the heating cavity, making it invisible or nearly invisible to the user when looking at the oven from the outside. Furthermore, scale buildup on the tray unit is also invisible or nearly invisible from the outside. In cases where the heating element has two coils with curved and partially straight sections, the support and tray unit can be positioned between the two heating coils (the straight sections). This improves water evaporation while still providing good cooking performance through steam and the coils.

[0051] Cleaning the tray unit is simplified due to its bowl-shaped design and the possibility of removing it, but leaving it on the support without using it (when the steam function is off) will not significantly affect the baking results. If improved cooking results are desired, the tray unit can also be removed when the steam function is not in use.

[0052] The bowl-shaped portion may have a bottom as an evaporation surface, which is formed as a flat plane with a high edge, which can prevent water from leaking to the outside or at least reduce the possibility of leakage.

[0053] The bowl-shaped portion can be placed to the right or left of the upper heater (heating section) of the oven, or several tray units can be placed within the heating cavity at different locations within the heating section. The tray units can form containers, which can be made of, for example, 0.5mm thick stainless steel sheets, or have other thicknesses. When placed, the bowl-shaped portion can move, for example, directly along the outline of the outer heating coil of the upper heater, or it can move to other locations. The depth of the bowl-shaped portion relative to its upper edge can be, for example, 4mm, or 0.5mm to 6mm. The bowl-shaped portion can have a volume of 100ml or 300ml for water. This depth is determined through testing to achieve an appropriate ratio between the amount of water in the bowl-shaped portion and the appropriate distance from the heating element, thereby enabling the water to evaporate as quickly as possible.

[0054] In addition, other embodiments are also possible, specifically, the device can be used in existing built-in furnaces (e.g., glass or metal control panel versions) or pyrolysis furnaces (glass or metal control panel versions) with some building facilities.

[0055] The preset distance from the heating coil to the bottom of the bowl-shaped part can be selected, so that the heating of the material of the tray unit and the heating of the water in the bowl-shaped part are optimal (maximum).

[0056] The support can be made of stainless steel, glass, or any other material that can resist the typical temperatures and corrosion inside an oven. The support can be made using any known technique (e.g., a heating bracket made of die casting or a heating bracket made of sheet metal).

[0057] The term "cooking" can also refer to or be replaced by "baking," "heating," and other methods of preparing food by heating or radiation, with or without steam (vaporized water). This oven can also be designed as a built-in oven for kitchen solutions.

[0058] Water evaporators can be used not only for manual water addition but also as part of an automatic water addition system. They can also be used in ovens without steam generators or microwave technology. Water evaporators can also be applied to ovens without proper sealing (for full steam applications) because they do not generate excessive steam or overpressure. Attached Figure Description

[0070] Although specific embodiments have been shown and described herein, those skilled in the art will understand that various alternatives and / or equivalent implementations may be made in place of the shown and described specific embodiments without departing from the scope of this application. Generally, this application is intended to cover any adaptations or variations of the specific embodiments discussed herein.

[0071] Figure 1 The illustration shows a tray unit of a water evaporation device attached to a support member of the water evaporation device at a heating coil, according to an embodiment of this application.

[0072] In a cooking appliance (not shown), a heating element HS may be mounted in the top region of the heating chamber, and the heating element HS, such as a simple heater, may have, for example, an internal heating coil HCC-in and another external heating coil HCC-out surrounding the internal heating coil HCC-in. The external heating coil HCC-out may be formed as a rectangle with four external main branches, and under one of such external main branches, the bowl-shaped portion BS of the tray unit 2 may be positioned, for example, when the tray unit 2 is placed in the operating position OP, one of these four external main branches extends entirely above the water in the bowl-shaped portion BS. While extending, the bowl-shaped portion BS is at least partially located below a branch of the internal heating coil HCC-in, which is positioned next to a particular external main branch of the external heating coil HCC-out, and may extend at least partially parallel to the latter. The length of the bowl-shaped portion BS in the longitudinal extension direction may be the same as or longer than the length of the particular external main branch of the external heating coil HCC-out. Therefore, heat from at least the external main branch of the external heating coil HCC-out (and possibly from the internal heating coil HCC-in) can be used to heat the water in the bowl-shaped section BS to optimal conditions and vaporize the water in the bowl-shaped section BS with high efficiency.

[0073] The water evaporation device 1 includes a support 3, for example made of a single bent rod 3a, which can be attached to the outer main branch of the outer heating coil HCC-out, or to the adjacent branch of the inner heating coil HCC-in.

[0074] The support member 3 includes an inlet portion ES formed as a cage structure and a sliding portion SL for the tray unit 2; water for evaporation in the heating chamber can be filled into the tray unit 2, wherein the tray unit 2 is configured to be attached to the support member 3, and wherein the tray unit 2 has a bowl-shaped portion BS for receiving water; wherein, after the tray unit 2 is inserted into the support member 3 through the inlet portion ES, it can be placed on the sliding portion SL and slide along the sliding portion SL. The tray unit 2 may have a circumferential edge M that can form the upper sidewall of the bowl-shaped portion BS.

[0075] Regarding the inlet portion ES, there are no general limitations on its possible shape, and several possible embodiments exist. Although the main part of this specification considers a cage-like structure for the inlet portion ES, with some possible annular portions on the left and / or right sides, the inlet portion ES is not limited to this. In other words, the inlet portion ES may, for example, be a straight extension of the sliding portion SL (on its left and right sides) or have other shapes.

[0076] When tray unit 2 is placed on support 3, facing the front side visible from the opening of the heating chamber, tray unit 2 may have a retaining portion HP, for example as a flat plate, which can be inclined from the horizontal plane toward the bottom of the chamber. The retaining portion HP may have a mark representing a steam symbol. The user can grasp the retaining portion HP to push and pull tray unit 2 along the sliding portion SL and through the inlet portion ES. At the opposite end of tray unit 2, similar inclined end plates may be present, which can help push tray unit 2 through the inlet portion ES and through the rear end portion RES of support 3. The end plates (e.g., sled-shaped) can help slide tray unit 2 horizontally when abutting the horizontal rod portion of the curved rod 3a at the rear end portion RES. Support 3 may be attached to the external main branch of the external heating coil HCC-out by means of at least the horizontal rod portion of the curved rod 3a at the rear end portion RES and the horizontal rod portion of the curved rod 3a at the inlet portion ES, for example by welding or by means of other retaining elements, such as clamps or other fixing structures. Figure 1 In the middle, the rear end RES has a cage-like structure with two rings, each ring having a bent rod 3a that passes horizontally through the outer main branch of the outer heating coil HCC-out and contacts the bottom of the outer main branch. The inlet ES has, for example, a cage-like structure with a horizontal ring that can pass horizontally through the outer main branch of the outer heating coil HCC-out at its bottom.

[0077] The tray unit 2 includes at least one first left sliding protrusion LP1 and at least one second left sliding protrusion LP2, both of which are flat and extend laterally outward from the circumferential edge M on the same lateral first side of the tray unit 2. The tray unit 2 also includes at least one first right sliding protrusion RP1 and at least one second right sliding protrusion RP2, both of which are flat and extend laterally outward from the circumferential edge M on the same lateral second side of the tray unit 2. The lateral second side of the tray unit 2 is opposite to the lateral first side of the tray unit 2.

[0078] The support member 3 may include a rear end RES, at which a bending rod 3a bends upward from the sliding height of the sliding part SL to form a rear vertical stop RVS for the second left sliding protrusion LP2 and / or the second right sliding protrusion RP2 of the tray unit 2. Above the rear vertical stop RVS, the bending rod 3a may be bent in the horizontal direction. The bending rod 3a may be attached to the outer main branch of the heating coil HCC and / or another branch of the heating coil HCC.

[0079] Figure 2 The tray unit of a water evaporation apparatus according to an embodiment of this application is shown.

[0080] like Figure 2 As shown in the embodiment, the tray unit 2 may include a first left sliding protrusion LP1 and a second left sliding protrusion LP2. Both protrusions are flat and extend laterally outward from the circumferential edge M on the same lateral first side of the tray unit 2. The first left sliding protrusion LP1 is located at a first distance d1 from the first end 2a of the tray unit 2, and the second left sliding protrusion LP2 is located at a second distance d2 from the first end 2b of the tray unit 2. The second distance d2 is greater than the first distance d1. Furthermore, the tray unit 2 may also include a first right sliding protrusion RP1 and a second right sliding protrusion RP2. Both protrusions are flat and extend laterally outward from the circumferential edge M on the same lateral second side of the tray unit 2. The lateral second side of the tray unit 2 is opposite to the lateral first side of the tray unit 2. The first right sliding protrusion RP1 is located at a third distance d3 from the first end 2a of the tray unit 2, and the second right sliding protrusion RP2 is located at a fourth distance d4 from the first end 2a of the tray unit 2. The first distance d1 and the third distance d3 may be equal to or different from each other. The second distance d2 and the fourth distance d4 may be equal to or different from each other. The tray unit 2 may be configured such that at the upper end of the circumferential edge M, the tray unit 2 may have equal thickness and width along the entire longitudinal extension direction L (except where the sliding part protrudes from the circumferential edge M).

[0081] The tray unit 2 may have a retaining portion HP at the first end 2a, for example as a flat plate that extends from the circumferential edge M toward the front and against the longitudinal extension direction L, and has a steam mark to allow the user to hold the tray unit 2 when attaching and / or detaching it from the support (not shown).

[0082] exist Figure 2 In the diagram, the second left sliding protrusion LP2 and the first right sliding protrusion RP1 are shown to have the same shape and equal size, with only the first left sliding protrusion LP1 differing in shape and size.

[0083] Typically, all these sliding protrusions (LP1, LP2, RP1, RP2) can be implemented as flat portions (which can be entirely composed of the bowl-shaped portion BS and the circumferential edge M, and can be integral with the bowl-shaped portion BS and the circumferential edge M), extending laterally outward from the circumferential edge M on a specific lateral first or second side of the tray unit 2, and can form a sled structure / shape (e.g., almost triangular when viewed from above), which facilitates their sliding along the rod of the sliding portion. From a top view, this sled structure / shape can be triangular or similar to a triangle. Figure 2 In the example, the first left sliding protrusion LP1 differs from the triangular shape, such that at least a portion of the sled structure / shape extends perpendicularly to the circumferential edge M and forms a stop structure / shape or locking structure / shape CS facing the first end 2a. Through this stop structure / shape or locking structure / shape CS, the first left sliding protrusion LP1 can abut against the vertical rod portion of the inlet to stop its further sliding movement toward the inlet and toward the cavity opening (not shown). At this particular stop position, the so-called service position of the tray unit 2 can be reached. The first distance d1 can be, for example, one-third of the entire length of the tray unit 2, and the second distance d2 can be two-thirds.

[0084] The bottom of the bowl-shaped portion BS may include a reinforcing structure RS as a ridge, the reinforcing structure RS extending along a predetermined length less than the length or width of the bowl-shaped portion BS along or perpendicular to the longitudinal extension direction L. The reinforcing structure RS may be a first reinforcing structure RSa extending along the longitudinal extension direction L and a second reinforcing structure RSb perpendicular to the longitudinal extension direction L. During exposure to high-temperature environments, these reinforcing structures RS can improve the stability and rigidity of the tray unit 2. Furthermore, when the tray unit 2 is pulled, the ridge can act as an obstacle to reduce water movement.

[0085] The bowl-shaped portion BS may include a maximum liquid level mark ML located inside the circumferential edge M and an inner bowl bottom region IBR, which forms a further bowl with a bottom volume at the bottom of the bowl-shaped portion BS. The inner bowl bottom region IBR may have its own circumferential edge, which is closer to the interior of the bowl-shaped portion BS than the circumferential edge M. Between these two edges, there may be another raised region EM, forming a forced upper boundary region of the inner bowl bottom region IBR (and a step between the circumferential edge M and the inner bowl bottom region IBR). The inner bowl bottom region IBR may have a volume of, for example, 100 ml, and at the maximum liquid level mark ML, the bowl-shaped portion BS may have a total volume of, for example, 300 ml. At the maximum liquid level mark ML, there is still a sufficient difference in height to the upper top of the circumferential edge M so that even with moderate sliding movement of the tray unit 2, the risk of water overflowing is very low, even when filled to the maximum liquid level mark ML. The maximum liquid level mark ML may be placed on both sides of the circumferential edge M so that it can be seen from all directions once the oven is placed in the kitchen unit. If a user decides to pour in more water than the maximum liquid level mark ML specifies, he / she can still do so (for example, tray unit 2 can hold a total of 300ml). However, there is a risk of water overflowing.

[0086] Tray unit 2 can be designed with a two-step bottom protrusion starting from the inner bowl bottom area IBR. This design has two advantages. First, it increases the overall structural rigidity, thereby minimizing temperature deformation. Second, it clearly specifies the amount of water to be poured.

[0087] Figure 3 A perspective view of an oven having a water evaporation apparatus in an operating position, according to an embodiment of this application, is shown.

[0088] Figure 3 The view essentially shows the heating chamber HC of the oven 10 viewed from the front when the door is open (the door is not shown). It can be seen that in this embodiment, the water evaporation device 1 with support 3 is located on the right side of the heating section of the chamber. The heating section is located at the top of the heating chamber HC. In a further embodiment not shown, the support 3 and the tray unit 2 may also be placed in another location on the heating section, for example, above the middle or left side of the heating chamber HC. Figure 3 The tray unit 2 is shown in the operating position, which can be identified by the fact that the tray unit 2 is fully positioned (slidable) within the support 3, and only the first end with the retaining part HP and the steam mark is visible from the front opening of the heating chamber HC. When water vaporizes, the heating fan helps to distribute the steam within the heating chamber HC.

[0089] When the door is open, the user can clearly see the retainer HP marked with a steam indicator. Even while wearing heat-resistant gloves, the tray unit 2 can be grasped via the retainer HP. By pulling the retainer HP, the user can partially pull the tray unit 2 to pour out fresh water, or manipulate the tray unit 2 to remove it completely (e.g., ...). Figures 7a-7c (As shown in the instructions for cleaning or storage).

[0090] In the operating position, if the oven fan (located inside the oven cavity) is active during heating, it helps to evaporate water more quickly and improves steam distribution within the cavity. Tray unit 2 can also operate without being filled with water, but it will not generate steam during cooking. If steam generation is not required during cooking, it is recommended to remove tray unit 2 from the heating cavity HC. Since it partially covers the heating element, it may negatively impact grilling or baking results. Furthermore, it is recommended to remove tray unit 2 during pyrolysis to extend its lifespan and prevent discoloration.

[0091] Figure 4 A side view along a cut in an oven having a water evaporation device, according to an embodiment of this application, is shown.

[0092] Figure 4 The side view is a view taken from the right side of the heating cavity HC of the oven 10, with the support member 3 and tray unit 2 placed inside the heating cavity HC. Therefore, the side view shows the longitudinal extent of the support member 3 and tray unit 2 extending from the opening towards the rear wall of the heating cavity HC within the heating cavity HC. It can be seen that the inlet portion ES and its cage-like structure can be placed at a specific defined distance from the front opening of the heating cavity HC. Furthermore, the sliding portion SL extends beyond a predetermined length to its rear end portion RES, which can also form a cage-like structure. Both the inlet portion ES and the rear end portion RES can be mounted onto the heating coil of the heating element. The rear end portion RES can still be at least partially extended along the predetermined length from the rear wall of the heating cavity HC when in the operating position.

[0093] Figure 5 The image shows a view from the bottom of the oven to the tray unit of the water evaporation device and the support member of the water evaporation device according to an embodiment of this application.

[0094] The view of the support 3 and tray unit 2 from the bottom of the heating chamber is as follows: Figure 5 As shown, only the front part of the tray unit 2 (around the first left sliding protrusion LP1 and the first right sliding protrusion RP1 and around the entrance ES) is located inside the cage structure of the entrance ES and is in the service position. This can be identified by the fact that the first left sliding protrusion LP1 abuts against the cage structure of the entrance ES, thereby stopping the sliding movement of the tray unit 2 in the forward direction.

[0095] The first left sliding protrusion LP1 and / or the second left sliding protrusion LP2 and / or the first right sliding protrusion RP1 and / or the second right sliding protrusion RP2 may have at least a partially flat wing (flat sled) shape, which has a protrusion EMB on its underside, the protrusion EMB being perpendicular to the circumferential edge M and extending in a first or second lateral direction, so that the tray unit 2 slides along the sliding portion via the protrusion EMB. The protrusion EMB may have a ridge shape to reduce the ratio between the bending rod 3a of the sliding portion SL and the specific sliding protrusion, and to increase the rigidity of the wing shape / sled shape / sled structure.

[0096] The entire support member 3 can be provided by a single bent rod 3a, which is bent into two parallel branches having an inlet ES, a rear end, and a sliding portion SL. Specifically, the sliding portion SL can have a left branch SLL and a right branch SLR formed by the bent rod 3a, the left branch SLL and the right branch SLR extending parallel to each other from the inlet ES, the distance dl between them being greater than the width w of the tray unit 2, and the first left sliding protrusion LP1 and the second left sliding protrusion can slide along the left branch SLL, and the first right sliding protrusion RP1 and the second right sliding protrusion can slide along the right branch SLR, and / or, wherein the left branch SLL and the right branch SLR are parallel to the outer main branch of the heating coil HCC (e.g., Figures 7a-7c (As shown).

[0097] The inlet section ES may have a left ring formed by a curved rod 3a (when viewed from below), which extends downward from the left branch SLL of the sliding section SL to the transverse central region (towards the right branch SLR), and then returns from the ring in the central region to the left branch SLL, rising vertically outside it to form the rod section RDS of the inlet section ES, and rising to a height accessible to the heating coil HCC. This left ring extends horizontally along the longitudinal extension direction (towards the rear wall) until it turns horizontally to the right and passes through the heating coil HCC (also as...). Figure 1 The outer main branch (as shown) then passes over the right branch SLR and turns vertically downwards to the right loop formed by the curved rod 3a, which can extend to the transverse center area (towards the left branch SLL) and return to the right side from the middle area again, then goes up again to the position of the right branch SLR, and then forms the right branch SLR.

[0098] Figure 5The diagram also shows a first reinforcing structure RSa extending along the longitudinal extension direction and a second reinforcing structure RSb extending perpendicular to the longitudinal extension direction. These structures form a bowl shape from the bottom side of the bowl-shaped portion BS and extend as protrusions (ridges) into the internal volume of the bowl-shaped portion PS to create barriers there for water flow and to reduce overflow. Furthermore, the first reinforcing structure RSa and the second reinforcing structure RSb can improve the stability of the bowl-shaped portion BS and the entire tray unit 2.

[0099] The stop structure / shape or locking structure / shape CS can abut against the rod portion RDS and stop the pallet unit 2 from moving in the forward direction. The stop structure / shape or locking structure / shape CS can partially surround the vertical rod portion of the rod portion RDS in the lateral outer part and prevent movement towards the opposite lateral side (lateral second side) in this position, and hold the pallet unit 2 laterally stably in this service position.

[0100] Figure 6 A perspective view of an oven having a water evaporation apparatus in a service position, according to an embodiment of this application, is shown.

[0101] Figure 6 It showed something similar to Figure 3 The view of the oven 10 differs in that the tray unit 2 is partially pulled out to the service position SP, where the stop structure / shape or locking structure / shape of the first left sliding protrusion (not shown) abuts against the inlet and stops it there. The water evaporation device 1 can be refilled with water by the user from the front opening of the heating chamber HC in this position, so that even when filled to the maximum liquid level mark, the tray unit 2 will remain horizontal. This is because the portion of the water-containing tray unit 2 protruding from the inlet will not tilt due to gravity, as the remaining water volume and the rearward position of the tray unit 2 behind the inlet still have a greater mass.

[0102] Figure 7a The image shows a top view of a water evaporation apparatus according to an embodiment of this application, with the tray unit positioned on a support and in a service position.

[0103] exist Figure 7aThe image shows the standard orientation of tray unit 2 at its service position SP inside the support, inside the inlet ES, and inside the cage-like structure of the rear end RES. In this position, tray unit 2 rests on the left branch SLL and right branch SLR of the sliding portion, specifically via the first left sliding protrusion LP1 and the second left sliding protrusion LP2 (towards the first lateral side I) and via the first right sliding protrusion RP1 and the second right sliding protrusion RP2 (towards the second lateral side II). The first left sliding protrusion LP1 abuts against the rod RDS of the inlet ES. Tray unit 2 can be positioned below the external heating coil HCC-out, and the left branch SLL can be located near or directly within the internal heating coil HCC-in. Figure 7c ).

[0104] The rear end RES may have a cage-like structure formed as an extension of the left branch SLL and the right branch SLR.

[0105] Specifically, at the rear end RES, the bending rod bends upward from the sliding height of the right branch SLR, thereby forming a rear vertical stop RVS for the second right sliding protrusion RP2. Above the rear vertical stop RVS, the bending rod bends horizontally, and the bending rod can be attached to the outer main branch of the external heating coil HCC-out, thereby forming the right rear end RES-R. Furthermore, at the rear end RES, the bending rod bends upward from the sliding height of the left branch SLL, thereby forming another rear vertical stop RVS for the second left sliding protrusion LP2. Above the other rear vertical stop RVS, the bending rod bends horizontally (directly or in a loop), and the bending rod can be attached to the inner heating coil HCC-in and the outer heating coil HCC-out, thereby forming the left rear end RES-L.

[0106] Figure 7b A top view is shown of a tray unit located on a support of a water evaporation device according to an embodiment of the present application, when the tray unit is moved laterally to release the tray unit from the support.

[0107] Figure 7c The image shows a top view of a tray unit located on the support of a water evaporation device, after the tray unit has been released from the support, as described in an embodiment of this application, during further movement.

[0108] exist Figure 7aIn this configuration, the stop structure / shape or locking structure / shape CS partially surrounds the rod portion RDS. When the tray unit 2 is slightly pushed rearward, it can overcome the rod portion RDS laterally in the second lateral direction represented by the second lateral side II. The tray unit 2 can remain in the horizontal plane and rotate with its first end 2a in the second lateral direction represented by the second lateral side II, and with its second end 2b in the first lateral direction represented by the first lateral side I. Behind the first left sliding protrusion LP1 or at least behind the second left sliding protrusion LP2, the tray unit 2 can abut against or be very close to the left branch SLL. The difference between the width of the tray unit 2 and the distance between the left branch SLL and the right branch SLR can be at least as large as the lateral range of the stop structure / shape or locking structure / shape CS, so that when the tray unit 2 moves laterally from the rod RDS with the stop structure / shape or locking structure / shape CS, the stop structure / shape or locking structure / shape CS can laterally overcome the rod RDS, and the tray unit 2 still has sufficient space toward the right branch SLR at the second lateral side II, so that the tray unit 2 can be pulled out from the entrance ES. Figure 7b This demonstrates how pallet unit 2 overcomes the lateral movement of the rod RDS. Figure 7c In the middle, tray unit 2 has been pulled out from the inlet ES, further than the service position, the first left sliding protrusion LP1 is outside the inlet ES, and then tray unit 2 can be fully pulled out from the support and heating chamber, and can also be partially pulled towards Figure 7a Rotate back from the initial sliding position.

[0109] The material thickness of tray unit 2 can be, for example, 0.5 mm. Instructions for removing tray unit 2 can be written in symbolic form on the upper front edge of tray unit 2. The positions of the rod RDS and the sliding protrusion with a stop structure / shape or locking structure / shape CS can also be on the inlet ES and the corresponding other lateral side of tray unit 2. To return tray unit 2 to support 3, the user needs to perform the same steps backward (in reverse order).

[0110] In the above detailed description, various features are grouped into one or more examples for the purpose of simplifying this application. It should be understood that the above description is intended to be illustrative and not limiting. It is intended to cover all alternatives, modifications, and equivalents.
