Patent number: 6129007Abstract: An electric automatic pop-up toaster has a carriage and a pivotably connected manually operative arm for moving the carriage to a lowermost position for toasting in well-known manner. At the beginning of each toasting cycle, the arm is horizontal and a latching plate is magnetically held down to hold the arm and the carriage in a lowermost position. The arm presses against a wire spring to hold closed a power switch (not shown) that supplies power to heating elements of the toaster. The latching plate is (magnetically) released at the end of each toasting cycle by a timer. This allows the carriage to move upwards to pop-up toasted bread in a usual way. However should the carriage fail to move upwards when the latching plate is released, the arm is pivoted by a spring and tilted to the position shown in the Figure. The wire is therefore released and enters a slot in a bracket mounted to the carriage. The switch opens and remains open to prevent power being re-instated to the heating elements.Type: GrantFiled: February 1, 2000Date of Patent: October 10, 2000Assignee: Simatelex Manufactory Co., Ltd.Inventors: Chi Tong Chan, Chun Ying Yeh

Patent number: 6077552Abstract: A method and apparatus is provided for the monitoring of the doneness of a baked product without invasively contacting the baked product. An impact is directed against a side of the baked product, and the resulting flex distance due to the propagation of the impact through the baked product is measured. Both the impact and the resulting flex are preferably performed without direct physical contact with the baked product. The flex response time from the impact is compared to a pre-stored threshold, and if the flex response time is less than the threshold, a doneness signal is generated. The doneness signal may be used, for example, to control the baking process, and can be used for the automated monitoring of baked products in a commercial baking environment. The doneness signal can further be used, for example, to control either the baking dwell time, the oven temperature, or both, or to control other baking variables.Type: GrantFiled: August 17, 1999Date of Patent: June 20, 2000Assignee: Iowa State University Research Foundation, Inc.Inventors: Dale E.

Patent number: 5794521Abstract: An improved breadmaker not only has a baking pan placed inside a baking chamber above a heater but also a centrifugal fan for pushing air upward therethrough. A partition wall with upper and lower openings separates the fan from the baking pan such that the upwardly pushed hot air is caused to flow downward around the baking pan. The baking pan is thereby heated uniformly and heat energy is efficiently utilized. Many processing programs are stored for producing different kinds of bread by using different ingredients. Each processing program is assigned a code and can be selected by specifying the code associated with it from a control panel. Ingredients to be used in each of the programs may be in a premixed form in a package.Type: GrantFiled: August 21, 1997Date of Patent: August 18, 1998Inventor: Simon K. C. Yung

Patent number: 5735190Abstract: The present invention features a combination bread-baker and a convection oven that bakes or cooks food thoroughly and evenly. Air is circulated through the baking or cooking chamber via a fan disposed in the side of the baking/cooking chamber. Steam can be introduced into the baking/cooking chamber during a cooking cycle by means of a steam-generator. A water reservoir supplies water to a steam-generating tube that is contiguously adjacent a portion of the heating coil. A microprocessor digitally controls both the baking and the cooking cycles. A pair of sensors positioned about the baking/cooking chamber send signals to the microprocessor that indicate levels of both heat and humidity within the chamber. The sensors continuously monitor the baking or cooking conditions within the chamber. The microprocessor uses the updated information to continuously adjust either the amount of steam being introduced, or the speed of the fan for adjusting the circulating air.Type: GrantFiled: December 2, 1996Date of Patent: April 7, 1998Inventor: John C. K. Sham

Patent number: 5711606Abstract: The diagnostic system of the present invention monitors and accumulates the thermal signatures or characteristics during at least one operational mode of the cooking appliance. These thermal signatures or characteristics are collected--through the same temperature sensor used to regulate the temperature of the cooking appliance--and then stored in, for example, a look-up table. Advantageously, this may be accomplished without the need of special sensors or interface boards. The thermal signatures or characteristics may include first order or higher order temperature gradients, as well as temperature profiles. The stored thermal signatures provide a baseline from which the diagnostic system can detect and identify whether the cooking appliance is working under normal operating conditions.Type: GrantFiled: October 27, 1995Date of Patent: January 27, 1998Assignee: Technology Licensing CorporationInventor: Bernard G.

Patent number: 5705791Abstract: An automatic countertop toaster and its control that divides the toasting cycle into three thermodynamic phases related to a change in the physical characteristics of the toaster and the item being toasted. The time of each of the three phases is adjusted according to the user inputs and current conditions to obtain the proper toasting time. The invention disclosed uses a microcomputer to interface with the user and control the toaster. The measured or estimated time since the last toasting cycle and the temperature inside the toaster are used by the microcomputer in table lookups to set the times for the three thermodynamic phases of the toasting cycle. Two of the phases are further modified by the toasting mode (normal, frozen, bagel, frozen bagel, reheat) and the toast darkness setting selected by the user. The sum of the three phases after modification is the total toasting time.Type: GrantFiled: December 20, 1996Date of Patent: January 6, 1998Assignee: Whirlpool CorporationInventors: Timothy B. Sutton, Donald E. Schnautz, Patrick L. Glotzbach, Arlene Richardson

Patent number: 5665410Abstract: Disclosed is a method for preselected extension of the dough rise period for dough products prepared in an automatic breadmaker. The method includes the step of selecting an extended final dough rise period from a group of predetermined times programmed into the breadmaker controller. The selection may be made before initiating the kneading/degassing and rising cycles or during what would otherwise be the final dough rise period.Type: GrantFiled: December 28, 1995Date of Patent: September 9, 1997Assignee: The West Bend CompanyInventors: Joanne M.
