there may be some developments beyond that date, but I can explain the reasons ovens typically don't come with built-in toaster ovens and air fryers.
Design and Functionality: Toaster ovens and air fryers serve specific functions and have distinct designs optimized for their purposes. Incorporating all these functionalities into one appliance can lead to compromises in performance and usability. Toaster ovens, for example, require a specific configuration and heating elements to toast bread evenly, while air fryers need a different setup to circulate hot air efficiently for frying foods.
Cost and Pricing: Combining multiple functionalities into one appliance could significantly increase the manufacturing cost and, consequently, the retail price. Many consumers prefer the flexibility to buy separate appliances as per their needs and budget.
Space Constraints: Many kitchens have limited counter space, and including all these functionalities in one unit may not be practical for some users. Offering separate appliances allows people to choose what they need while still being space-efficient.
Customization: Some people might prefer a high-quality, dedicated toaster oven or air fryer for specific cooking requirements. Having separate appliances allows them to pick devices that suit their preferences and cooking habits.
Maintenance and Repairs: If an all-in-one appliance develops a problem with one of its functionalities, it might render the entire unit unusable until it gets repaired. With separate appliances, you can still use the functional parts while getting the faulty one fixed.
Market Demand: The demand for each appliance varies, and not everyone might be interested in having all functionalities in one device. Manufacturers tend to produce products that align with the majority of consumers' preferences.
While there are some combination appliances available on the market that offer multiple functions, the above reasons help explain why it's more common for ovens, toaster ovens, and air fryers to be separate standalone appliances. However, as technology and consumer preferences evolve, there may be changes in the market offerings. Always check the latest products and features available to see if there have been any developmentsdate.
