This steam oven / cooker / refrigerator combo achieves five functions: steaming, baking, refrigeration, air conditioning, and food insulation.

Description

Technical Field

[0001] This utility model relates to kitchen appliances, and in particular to a steam oven and refrigerator combo. Background Technology

[0002] In most parts of my country, summer temperatures are generally high. The large amount of heat generated during cooking makes the kitchen environment even more stuffy. Therefore, air cooling equipment in the kitchen has become a key facility to ensure a comfortable working environment. However, due to the complex layout of the external space of the kitchen, the installation of air conditioning outdoor units is difficult. At the same time, the small internal space of the kitchen makes it difficult to effectively deploy and use common air conditioning equipment in the kitchen. The problem of high temperature in the kitchen urgently needs to be solved.

[0003] In the kitchen appliance sector, steam ovens and refrigerators have garnered widespread attention due to their multifunctional integration. However, existing steam ovens and refrigerators suffer from significant technical flaws: First, the refrigeration and steaming / baking systems cannot operate simultaneously; they must run independently, resulting in poor interoperability and difficulty in meeting users' diverse and efficient cooking needs. Second, after the steaming / baking function is completed, the equipment quickly enters a heat dissipation phase. To prevent food from experiencing a sudden temperature drop due to heat dissipation, affecting its taste and quality, users are required to remove the food promptly. If the food cannot be consumed immediately, the equipment lacks an effective temporary heat preservation function. Third, during operation, the waste heat from steaming / baking, as well as the waste heat generated by the condenser of the refrigeration system, is typically directly discharged outdoors without effective recovery and utilization, resulting in energy waste and hindering energy conservation and emission reduction. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a steam oven and refrigerator that can achieve air conditioning and cooling, in light of the above-mentioned existing technology.

[0005] The second technical problem to be solved by this utility model is to provide a steam oven and refrigerator with countertop heat preservation effect, in view of the above-mentioned existing technology.

[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a steam oven and refrigerator integrated machine, including a shell and a cavity disposed inside the shell, characterized in that: an installation cavity is formed between the shell and the cavity, a refrigeration system is installed in the installation cavity, the cavity has a refrigeration air inlet and a heat dissipation air outlet, the refrigeration system has a cold air outlet and a hot air outlet, an air conditioning outlet is opened on the shell, and the cold air outlet can be fluidly connected with the refrigeration air inlet and / or the air conditioning outlet.

[0007] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: the all-in-one machine is installed inside a cabinet, a heat preservation area is formed on the countertop of the cabinet, the bottom of the heat preservation area has a heat preservation air duct, and the hot air blown out by the heat dissipation outlet and the hot air outlet is combined and sent into the heat preservation air duct.

[0008] The refrigeration system can have various structures. Preferably, the refrigeration system includes a compressor, a condenser, an evaporator, a cooling fan, and an indoor unit fan. The compressor, condenser, and evaporator are connected by refrigerant pipelines.

[0009] To avoid interference between the cold and hot air in the refrigeration system, the refrigeration system has isolated hot air channels and cold air channels. The condenser and cooling fan are located in the hot air channel, and the evaporator and indoor unit fan are located in the cold air channel. The outlet of the hot air channel constitutes the hot air outlet, and the outlet of the cold air channel constitutes the cold air outlet.

[0010] In a further preferred configuration, along the airflow direction, the indoor unit fan is located downstream of the evaporator, and the cooling fan is located downstream of the condenser. This arrangement allows the indoor unit fan to draw air into the evaporator, and the cooling fan to draw air into the condenser.

[0011] Further preferably, an expansion valve is installed on the refrigerant line between the condenser and the evaporator. With this configuration, the evaporation temperature can be controlled within the required range by adjusting the opening degree of the expansion valve and the compressor power.

[0012] The air conditioner vents can be located in multiple different positions. Preferably, the air conditioner vents are located on the front of the unit casing. This design places the air conditioner vents low, solving the problem of users' heads being directly exposed to cold air, resulting in a better user experience.

[0013] As a preferred embodiment of any of the above solutions, the refrigeration system can operate independently of the steaming and baking system of the steam-baking and refrigeration all-in-one appliance, or the refrigeration system and the steaming and baking system can operate simultaneously. With this configuration, the steam-baking and refrigeration all-in-one appliance has a linkage capability and higher utilization rate.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This steam oven and refrigerator combo integrates a refrigeration system installed in a cavity between the casing and the main body. The cavity has a refrigeration air inlet and a heat dissipation air outlet. When the cold air from the refrigeration system's outlet enters the cavity through the refrigeration air inlet, it refrigerates the food inside. When the cold air from the outlet exits through the air conditioning vent, it blows into the kitchen, enhancing the user's cooking experience. Furthermore, when the hot air from the refrigeration system's outlet and the heat dissipation air outlet converge and are delivered to the insulation duct at the bottom of the countertop, the remaining heat inside the cavity after steaming and baking, combined with the high-temperature air from the refrigeration system's outlet, keeps the food in the insulation zone warm. This steam oven and refrigerator combo integrates five functions: steaming, baking, refrigeration, air conditioning, and food insulation. Attached Figure Description

[0016] Figure 2 This is a partial structural diagram of the steam oven and refrigerator integrated machine according to an embodiment of the present invention. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 and Figure 2 As shown, the steam oven and refrigerator combo of this embodiment includes a housing 1 and a cavity 2 located inside the housing 1. The cavity 2 is a functional cavity that can realize the functions of steaming, baking, and refrigeration. The combo has a steam baking system, and an installation cavity 3 is formed between the housing 1 and the cavity 2. A refrigeration system 4 is installed in the installation cavity 3. The refrigeration system can operate independently of the steam baking system or operate simultaneously with the steam baking system to achieve linkage.

[0019] The cavity 2 has a refrigeration air inlet 21 and a heat dissipation air outlet 22. The refrigeration system 4 has a cold air outlet and a hot air outlet. An air conditioning outlet 11 is located on the front of the casing 1, connecting to the kitchen interior. Because the all-in-one unit is installed inside the cabinet 5, the air conditioning outlet 11 is positioned low to prevent the user's head from being directly exposed to cold air. The cold air outlet can be fluidly connected to the refrigeration air inlet 21, the air conditioning outlet 11, or both simultaneously. When the user needs to refrigerate food, the refrigeration air inlet 21 is opened, and the air conditioning outlet 11 is closed. When the user needs to cool the room, the air conditioning outlet 11 is opened, and the refrigeration air inlet 21 is closed.

[0020] The all-in-one machine in this embodiment also has a food warming function. The all-in-one machine is installed in the cabinet 5. A warming zone 6 is formed on the countertop of the cabinet 5. The bottom of the warming zone 6 has a warming air duct 7. The hot air blown out by the heat dissipation vent 22 and the hot air outlet is combined and sent into the warming air duct 7.

[0021] The refrigeration system 4 in this embodiment includes a compressor 41, a condenser 42, an evaporator 43, a cooling fan 44, and an indoor unit fan 45. The compressor 41, condenser 42, and evaporator 43 are connected by a refrigerant pipeline 46. An expansion valve 47 is installed on the refrigerant pipeline 46 between the condenser 42 and the evaporator 43. Along the airflow direction, the indoor unit fan 45 is located downstream of the evaporator 43, and the cooling fan 44 is located downstream of the condenser 42.

[0022] The refrigeration system 4 has a mutually isolated hot air passage 48 and a cold air passage 49. The condenser 42 and the cooling fan 44 are located in the hot air passage 48, while the evaporator 43 and the indoor unit fan 45 are located in the cold air passage 49. The outlet of the hot air passage 48 constitutes the hot air outlet, and the outlet of the cold air passage 49 constitutes the cold air outlet. By adjusting the power of the compressor 41 and the opening of the expansion valve 47, the evaporation temperature can be controlled within the required range, that is, the temperature of the cold air blown out of the cold air outlet can be controlled.
