DE102017004986A1 - Electric spray bottle for foodstuffs for evenly spraying the liquid on food when frying or preparing the dish - Google Patents

Abstract

In conventional cooking such as frying, liquid, mainly water, but also salt water and oil are often added during the turning. However, this cooking technique has not yet been systematically applied and the liquid is not ideally distributed. Experiments in the context of this invention have shown that a better cooking result can be achieved in frying when the water is sprayed into the pan with a high degree of consistency in highly heated dishes in the pan in the form of water particles of different sizes in different cooking phases. The sprinkled with constancy fine water particles are then immediately converted into hot steam and cook the food additionally. This achieves a similar effect to a combi steamer used in the catering industry (also called "combi steamer" or "steam oven"), which cooks the food simultaneously with steam and bakes it with hot air. The pores on the food surfaces are closed by frying. At the same time, the generated hot steam ensures that the food is cooked gently under uniform heat and that the vitamins are retained in the food. It is similar when preparing other foods such as salads, which should be sprayed evenly with spice liquid such as vinegar, seasoning and oil during preparation, which is difficult and difficult to achieve with conventional method. To achieve the cooking process described above, should here According to the invention, a specially designed electric spray bottle, which generates a constant stream of water particles of different sizes, from fine mist to coarse droplets, required for this purpose. The spray bottle is made of food grade and partially heat resistant materials and has at least one electric motor powered by at least one battery or battery pack. Three types of pump jet pump, submersible pump and air compressor are proposed. As an electric motor an electronically commutated BLDC motor with permanent magnet is preferred because of the small size and high acceleration. The spray nozzle of the spray bottle has two variants: Spray nozzle variant A: The spray bottle has a spray nozzle with adjustable size of sprayed liquid particles. Spray nozzle variant B: The Spray bottle has two parallel spray nozzles. Both spray nozzles are adjustable independently of each other for different sizes of sprayed liquid particles. The purpose of these double spray nozzles is to assist in rapid frying of the pan food in very high heat. The first spray nozzle sprays the finer water jet to produce sufficient steam replenishment in the pan; The second spray nozzle sprays coarser water jet to limit the temperature during cooking under high heat. In addition, the combination of water vapor and salt water möglich.Um to prevent the dispersion of the liquid when spraying delicate liquid such as spice liquid or oil, a splash guard is designed in front of the spray nozzle.

Description

Field of the invention:

The invention relates to the application in the kitchen for food according to the preamble of claim 1 and the kitchen appliance.

State of the art:

The present invention reports, which relate to spray bottle, such as US2006 / 0289679A1, US6109548A . DE3439388A1 . EP0365770A1 , are not specific to the application in the kitchen designed for food and therefore optimized neither by volume nor by material. Other commercially available spray bottles or spray cans, such as vinegar sprayers and oil sprayers, require laborious, intermittent manual operation and can not produce a constant stream of water particles of varying sizes needed for cooking. An electric continuous spray bottle with integrated electric motor for use in the kitchen is so far unknown. In the case of cooking, such as roasting, where the food to be sprayed with water or salt water during turning, is mainly operated manually. A uniform continuous distribution of the liquid is therefore not given. In addition, the spray bottle with two parallel spray nozzles, which are adjustable independently of each other with different sizes of sprayed liquid particles, also unknown.

Task:

In conventional cooking such as frying, liquid, mainly water, but also seasoning, salt water and oil are often added during turning. However, this cooking technique has not yet been systematically applied and the liquid is not ideally distributed. Experiments in the context of this invention have shown that a better cooking result can be achieved in frying when the water is sprayed into the pan with a high degree of consistency in highly heated dishes in the pan in the form of water particles of different sizes in different cooking phases. The sprinkled with constancy fine water particles are then immediately converted into hot steam and cook the food additionally. This achieves a similar effect to a combi steamer used in the catering industry (also called "combi steamer" or "steam oven"), which cooks the food simultaneously with steam and bakes it with hot air. The pores on the food surfaces are closed by frying. At the same time, the generated hot steam ensures that the food is cooked gently under uniform heat and that the vitamins are retained in the food. It is similar when preparing other foods such as salads, which should be sprayed evenly with spice liquid such as vinegar, seasoning and oil during preparation, which is difficult and difficult to achieve with conventional method.

In order to achieve the cooking process described above, according to the invention, a specially designed electric spray bottle, which generates a constant stream of water particles of different sizes, from fine mist to coarse droplets, is required. The spray bottle, an electric kitchen appliance with the features of claims 1 to 9, consists of food grade and partly heat resistant materials and has at least one electric motor, which is powered by at least one battery or battery unit.

Preferred embodiments of the invention and further advantageous features are disclosed in the dependent claims.

Description:

The kitchen utensil described, an electric spray bottle, is typically assisted by an electric motor which, as set forth in claims 1 to 4, allows the water or suitable liquid to be conveyed from a container to the outside. All components that come into contact with the liquid must be made of food-grade materials or have appropriate coating, in which case food-grade plastic, glass, ceramics and food-grade stainless steel are preferred. Due to the proximity to the heat source during cooking, the flash bottom made of heat-resistant material stainless steel and silicone is preferred. The advantage is that the speed of the electric motor is adjustable, so that the amount of water flow can be adjusted. A modern electronically commutated permanent magnet BLDC motor, for example, is very small and powerful, has very high acceleration, which facilitates one-handed operation during the cooking process. Another great advantage is that the spraying process can be carried out in a continuous and long-lasting manner, so that it is possible to leave the entire spraying device next to the food and to spray the liquid automatically via a flexible arm during work. Based on this, of course, any modern control methods can be implemented, such as e.g. Remote control, voice control.

There are three preferred embodiments of the invention according to the principles of a jet pump ( 1 ), a submersible pump ( 3 ) and an air compressor ( 2 ) proposed. Further Embodiments or combinations are possible according to claim 1.

The invention will be described below with reference to the embodiment with reference to the drawings. From the description and the drawings, further features and advantages of the invention will become apparent.

The electric motor ( 2a ) drives an impeller ( 9 ) with a diameter between 10 and 90 mm in the spray head ( 1 ), which passes the liquid through an immersion hose or a pipe ( 6 ) from the bottle ( 4 ) in the pump room ( 7 ) sucks. The aspirated fluid then exits under pressure from the spray nozzle ( 8th ) out. The electric motor ( 2a ), a preferred electronically commutated BLDC motor with permanent magnet whose diameter is smaller than 80 mm, is at least one battery or battery unit ( 3 ) provided. Both components ( 2a . 3 ) are preferably in the spray head ( 1 ) integrated. At or in the handle of the spray head ( 1 ) is at least one switch ( 5a ), the speed of the electric motor ( 2a ) directly or indirectly and thereby control the flow rate, regardless of whether the switch ( 5a ) the shape of a pistol trigger like levers ( 5a ) or the shape of a push button ( 5b ) or button ( 5c ) or other modern electronic switch, the switch ( 5a . 5b . 5c ) as required on the spray head ( 1 ) is positionable. The spray nozzle ( 8th ) is rotatable about the spray axis and thereby different spray types such as "coarse, fine" can develop.

For simplicity, the design of the control electronics and connecting wires for switch and motor are omitted in the drawings.

2 shows a spray bottle with an electric motor ( 2 B ), whose diameter is smaller than 80 mm, according to the principle of an air compressor. The electric motor ( 2 B ) drives an air compressor ( 10 ), the air through an air line ( 13 ) from the outside into the bottle ( 4 ) and thereby the air pressure in the spray bottle ( 4 ) elevated. The liquid in the spray bottle then passes through the immersion hose or tube under pressure ( 6 ) from the spray nozzle ( 8th ) out. Further embodiments are similar to the above for 1 described.

3 shows a spray bottle with an electric motor ( 2c ) according to the principle of a submersible pump. The electric motor ( 2c ), whose diameter is smaller than 80 mm, drives a submersible pump ( 11 ) at the end of an immersion hose or pipe ( 6 ) and the liquid through the immersion hose or the pipe ( 6 ) from the bottle ( 4 ) into the spray nozzle ( 8th ) pumps. The pumped up liquid then exits under pressure from the spray nozzle ( 8th ) out. Further embodiments are similar to the above for 1 described.

In order to avoid the dispersion of the liquid when spraying delicate liquid such as spice liquid or oil, a splash cap ( 14 ) in front of the spray nozzle, which has a diameter of greater than 5 cm and the shape of a light or horn.

The spray bottle mentioned above can be replaced by a second parallel spray nozzle ( 8th ). Both spray nozzles are adjustable independently of each other for different sizes of sprayed liquid particles. The purpose of these double spray nozzles is to assist in rapid frying of the pan food in very high heat. The first spray nozzle sprays the finer water jet to produce sufficient steam replenishment in the pan; The second spray nozzle sprays coarser water jet to limit the temperature during cooking under high heat. In addition, the combination of water vapor and salt water is made possible by two separate chamber are integrated in the bottle. For the sake of simplicity, the configuration of the double spray nozzles will be omitted in the drawings.
