Description

Air fryer
Technical field
The utility model relates to kitchen tools more particularly to air fryers.
Background technique
European Union has issued (EU) No. 2017/1357 resolution on July 21st, 2017, defines low voltage directive in the resolution The limit value condition that harmonized stndard EN60335-2-9:2003+A13:2010 is executed, since the date of issuance comes into force.
The opposition that this resolution proposes EN60335-2-9:2003+A13:2010 criteria section content from Germany and Norway Opinion.They think insufficient about the regulation of non-functional contact surface temperature limit in 11 chapter of standard " fever " clause.Especially It is to allow the temperature limit of several exemptions in standard, and manufacturer is allowed to double temperature limit, at most only needs to add warning clause Or label is on the surface that temperature is more than limit value.And the alarm tag required in 7.1 clause of standard may be with international warning color It is different.Ambiguous due to standard requirements, standard can be read as can be omitted the temperature rise test at the certain positions of product.So as to Cause the temperature limit for ignoring entire product or temperature limit that can double.Therefore, the risk of burning still has.And this A standard is considered being unsatisfactory for low voltage directive 2014/35/EU.
In view of safety requirements needs to be improved and waits the revision of appropriate criteria, primary standard EN60335-2-9:2003+ A13:2010 should do limitation appropriate and could issue in the official report of EU Committee, and the limitation made requires detailed interior Have at following 3 points:
Limitation one: the annotation b of Chapter 11 acceptance of the bid Z101: when the limitation due to product structure or size, lead to above temperature When ceiling value cannot be satisfied, 2 times that resulting maximum temperature rise does not allow more than limit value in table Z101 are tested, and need in phase It closes surface and adds high temperature alarming sign;
For the high temperature alarming sign required in table Z101 annotation b in two: the 7.1 chapters of limitation;
Limitation three: the requirement in Chapter 11 Z10X chapters and sections about ventilation hole temperature rise test: within 25mm around ventilation hole Surface temperature rise from test.
Increase above 3 points of the limitation for the resolution to be not difficult to find out: the temperature rise that 1. all relevant surfaces measure cannot surpass The limit value of Z101 is crossed, even if being not above 2 times of limit value, " high temperature warning " in 7.1 chapters and sections can not be sticked in relevant surfaces Mark;2. all relevant surfaces around ventilation hole within 25mm range must all carry out temperature measurement, and no more than table The limit value of Z101.
Generally speaking, for the manufacturer of China, the publication of (EU) No. 2017/1357 resolution will be to outlet Europe The similar products such as grill, oven, air fryer, the toaster of alliance produce bigger effect, all to be suitable for standard EN60335-2-9 The requirement of the temperature rise test of the product of range, becomes more stringent.
Existing air fryer, including cooker racks, pot body and lid, the cooker racks is interior to be equipped with the sky placed for pot body Chamber, in the cavity, one end of lid and the cooker racks tail portion are hinged, the other end and cooker racks of the lid for the pot body position The connection of front open-close type, fryer control device is installed in the front of the cooker racks.
Hot-air channel and cold air path are provided in existing air fryer, hot-air channel is used for food heating, and cold air is logical Road avoids air fryer surface temperature excessively high for cooling down.It is communicated with the atmosphere at the top of the hot-air channel, the bottom of hot-air channel Portion is connected to pot body cavity, and heating tube component, the hot-air channel heating tube component top are installed in the middle part of the hot-air channel First fan is installed, when needing hot wind, heating tube component is generated heat the cold air heating of bringing the first fan into;Cold air path is set to pot It in the interlayer of frame, is communicated with the atmosphere at the top of cold air path, the top of cold air path is equipped with the second fan, the outlet of cold air path Positioned at the bottom of cooker racks.Hot-air channel and cold air path in air fryer are completely independent setting, the two and the company of being not present Logical part.
In existing air fryer, flow through the intracorporal waste hot gas of pot be expelled directly out do not do cooling processing.So In the prior art, air fryer is at vent locations, it may be difficult to by surveying in Chapter 11 Z10X chapters and sections about ventilation hole temperature rise The requirement of examination, thus be difficult to meet (EU) No. 2017/1357 resolution, so the requirement of instruction 2014/35/EU can not be met, Serious influence is formed on products export EU market.
