Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and in particular to a water tank structure for a cooking device. Background Technology

[0002] With the development of cooking equipment, steam ovens have gradually become important cooking tools in the kitchen. However, during repeated cooking processes, a large amount of grease, steam condensation, and other dirt accumulates on the inner surface of the steam oven cavity. This not only affects the lifespan of the equipment but also poses a potential threat to food hygiene. Therefore, how to maintain the cleanliness of the steam oven cavity has become an urgent problem to be solved.

[0003] Most steam ovens on the market are equipped with a cavity cleaning system, which requires hot water to effectively improve cleaning results. However, many steam ovens use a dedicated water tank at the bottom with a heating element, providing a continuous supply of hot water. This, however, requires additional electricity to heat the water, reducing the oven's energy efficiency and increasing energy consumption. Furthermore, insulation cotton needs to be wrapped between the outer shell and the inner cavity of the steam oven. This insulation serves two purposes: firstly, to retain heat and reduce heat loss; and secondly, to ensure the outer shell remains within a safe temperature range, preventing overheating and potential burns to the user.

[0004] Therefore, how to use the heat from existing cooking equipment to provide hot water for the cleaning system without increasing additional energy consumption has become a technical problem that needs to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a water tank structure for a cooking device. By setting a water tank between the inner liner and the outer shell, during the use of the cooking device, the heat on the surface of the cavity is conducted to the water tank, which raises the temperature of the water inside the water tank and provides hot water for the cavity cleaning system to clean the cavity.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A water tank structure for a cooking device includes an inner liner and an outer shell fitted over the outer side of the inner liner. A water storage cavity is provided between at least two outer sides of the inner liner and the outer shell. The water storage cavity is the internal space of an independent water tank, or the water storage cavity is a cavity formed between the outer sides of the inner liner and the inner shell. The inner shell is located between the inner liner and the outer shell.

[0008] By using a water storage cavity located between the outer side of the inner tank and the outer shell, whether inside the independent water tank or within the cavity formed between the outer side of the inner tank and the inner shell, this invention can effectively transfer heat from the inner tank to the water storage cavity, thereby heating the water in the tank. This design can provide hot water during the cleaning process of cooking equipment, improving cleaning efficiency and reducing water heating time.

[0009] Preferably, there are one or more water storage chambers, which are interconnected or sequentially connected. This design ensures uniform water flow, thereby improving water temperature stability.

[0010] Preferably, the water storage chamber has an inlet and an outlet. When there are multiple water storage chambers that are interconnected or sequentially connected, two water storage chambers are connected by a connecting pipe.

[0011] Preferably, the inlet and outlet of the same water storage chamber are located on different sides.

[0012] Preferably, the outlet of the water storage chamber connected to the chamber cleaning system is located at the lowest point of the water storage chamber.

[0013] The outlet connecting the water storage chamber to the chamber cleaning system is located at the lowest point of the water storage chamber. This ensures that the water in the water storage chamber can be completely drained, avoiding the problem of water residue. Especially when the cooking equipment is not in use, it helps the water tank to dry and clean, reducing the formation of limescale.

[0014] Preferably, a steam outlet is provided at the top of the water storage chamber or at the top of the multiple interconnected water storage chambers, and the steam outlet is connected to a pressure valve;

[0015] When the pressure valve detects that the pressure in the water storage chamber has risen to a preset value or above, the pressure valve opens, and the steam in the water storage chamber is discharged through the steam outlet.

[0016] When the pressure valve detects that the pressure in the water storage chamber is lower than a preset value, the pressure valve automatically closes.

[0017] The steam outlet at the top of the water storage chamber, along with the connected pressure valve system, automatically releases steam when the water temperature or pressure in the tank is too high, effectively preventing safety hazards caused by high pressure. This design ensures the safety of the equipment during long-term operation, avoiding malfunctions or damage caused by excessive pressure.

[0018] Preferably, the inner liner is a metal shell with an opening on the front, and when the water storage cavity is the internal space of an independent water tank, the independent water tank is made of metal or plastic.

[0019] The independent water tank and the inner liner have the same shape design, and the independent water tank made of metal is tightly welded to the outside of the inner liner, which increases the durability of the water tank and reduces damage caused by factors such as water tank expansion or thermal expansion and contraction.

[0020] Preferably, the independent water tank is fitted to the inner liner, and the shape of the fitted surface of the independent water tank is consistent with the shape of the corresponding outer surface of the inner liner.

[0021] Preferably, the water tank, inner shell, inner liner and outer shell are provided with heat insulation material.

[0022] The water tank, inner shell, and inner liner are all wrapped with heat-insulating material, effectively reducing heat loss and preventing the cooking equipment's outer shell from overheating, thus improving the safety of the internal components. This design not only enhances the equipment's energy efficiency but also protects users from burns during operation.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] This application effectively reduces energy waste by improving the heat transfer efficiency and insulation performance of the water tank structure, optimizes the water heating and usage process, and enhances the overall energy efficiency of the cooking equipment, which is in line with the modern energy-saving and environmentally friendly design trend.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0031] Example 1

[0032] The cooking device in this embodiment is a steam oven, such as... Figure 1-2 The water tank structure includes an inner liner 2, multiple independent water tanks 1 and an outer shell 3. The outer shell 3 is fitted on the outside of the inner liner 2, and the independent water tank 1 has an internal water storage cavity.

[0033] The inner pot 2 is a metal shell with an opening at the front end, used for cooking food. The opening end is used for storing food. A heating device is arranged on the left side of the inner pot 2 to provide a heat source during the steaming and baking process, so that the temperature of the inner space and the surface of the inner pot 2 rises.

[0034] Multiple independent water tanks 1 are designated as upper water tank 11, rear water tank 12, right water tank 13, and lower water tank 14, which are fixedly attached to the outer surfaces of the upper, rear, right, and lower sides of the inner tank 2, respectively. Each independent water tank 1 is equipped with an inlet and an outlet. The inlet of one of the upper water tanks 11 (or the rear water tank 12 or the right water tank 13) is connected to a tap water pipe through an inlet pipe 111, or it may only have an inlet and be manually replenished with water. The outlet of the lower water tank 14 is connected to the cavity cleaning system through an outlet pipe 141, or it may only have an outlet and release hot water for other uses through a control valve. The inlet and outlet of two adjacent water tanks are connected by a connecting pipe 112, that is, the upper water tank 11, the rear water tank 12, the right water tank 13 and the lower water tank 14 are connected in series by the connecting pipe 112. During the use of the cooking equipment, the heat on the surface of the inner pot 2 is conducted to the independent water tank 1, which raises the water temperature in the independent water tank 1 and provides hot water for the cavity cleaning system to clean the inner pot 2.

[0035] To improve the heat conduction between the inner tank 2 and the independent water tank 1, the independent water tank 1 is made of stainless steel or plastic. To ensure that the independent water tank 1 and the inner tank 2 are tightly attached, the shape of the contact surface of the independent water tank 1 is consistent with the shape of the corresponding outer surface of the inner tank 2. The independent water tank 1 and the inner tank 2 are fixed by mechanical connection such as welding, riveting, or bolts, or by ceramic adhesive, or a combination of several methods.

[0036] The inlet and outlet of the same independent water tank 1 are not located on the same side of the independent water tank 1. The distance between them on the independent water tank 1 should be as large as possible. For example, in the upper water tank 11, the inlet is located at the front left corner of the upper water tank 11, and the outlet is located at the rear right corner of the upper water tank 11, so that as much of the heated water that comes in first is discharged first.

[0037] The water outlet pipe 114 connecting the cavity cleaning system is placed at the lowest point of all the independent water tanks 1. In this embodiment, the water outlet pipe 114 is located at the bottom of the lower water tank 14, so that when the cooking equipment is not used for a long time, it is convenient to drain all the water in the tank.

[0038] A steam outlet 113 is provided at the top of the upper water tank 11 and connected to a steam pipe. The steam pipe extends to the top of the cooking equipment cabinet. A pressure valve 114 is provided on the steam pipe. When the cooking equipment is used continuously for a long time, the water in the upper water tank 11 may boil, causing the pressure in the upper water tank 11 to rise. When the pressure reaches a preset value, the pressure valve 114 opens, and steam is discharged to the outside of the cooking equipment cabinet through the steam pipe to reduce the pressure in the upper water tank 11. When the pressure in the upper water tank 11 drops to the preset value, the pressure valve 114 automatically closes.

[0039] Rock wool and other heat-insulating materials are wrapped around the outer surfaces of the independent water tank 1 and the inner liner 2 to improve the heat preservation effect of the inner liner 2 and the independent water tank 1, reduce heat loss, and at the same time lower the temperature of the space between the inner liner or independent water tank and the outer shell of the cooking equipment, protecting the electrical components of the cooking equipment in a safe environment.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is that in this embodiment, there is only one independent water tank 1, which is L-shaped. In this embodiment, part of the independent water tank 1 is located below the inner tank 2, and the other part is located on the right or rear side of the inner tank 2. The bottom of the independent water tank 1 is provided with a water outlet, and the top of the independent water tank 1 is provided with a water inlet.

[0042] Example 3

[0043] The difference between this embodiment and Embodiment 1 is that, in this embodiment, a water storage cavity is formed by welding a metal inner shell to the outer side of the inner liner 2, with the inner shell located between the inner liner 2 and the outer shell 3. Insulating material is wrapped around the outer sides of the inner shell and the inner liner 2.

[0044] Example 4

[0045] The difference between this embodiment and Embodiment 1 is that, as Figure 3 As shown, the independent water tank 1 in this embodiment includes an upper water tank 11 and a lower water tank 14. The outlet of the upper water tank 11 is connected to the inlet of the lower water tank 14 through a connecting pipe. The rest of the structure is the same as in embodiment 1.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
