Description

Magnetic detachable primary-secondary double-taste pot

Technical Field

The utility model relates to a tableware field especially relates to a slaughterhouse pan, chafing dish pan field for culinary art, and concretely relates to master and slave mandarin duck pot can be dismantled to magnetic force, is particularly useful for the pan of electromagnetism stove heating culinary art.

Background

The chafing dish is one of the main ways of gathering food for people at present in the current society, and is widely praised because the chafing dish can provide different tastes and cook different food materials, and can meet the eating habits of most of people. Particularly in the southwest area, areas of cities centered on Chongqing and Chengdu, chafing dish is well known, and people have a diet of eight-to-nine choices of chafing dish. After long-term development, the hotpot is developed from an original single-lipstick pot to a later mandarin duck pot, and a primary pot and a secondary pot or a primary and secondary mandarin duck pot cater to most people with the taste of the hotpot. Today, the current chafing dish tableware can basically meet the selection of people with different tastes for diners; therefore, the current mandarin duck pot does not have subversive development and innovation, and the currently used and more mainstream mandarin duck pots have two types:

the double-taste pot is a typical double-taste pot, namely a closed rib is welded in the middle of a complete pot to divide the pot into two parts, namely the double-taste pot which is axisymmetric or centrosymmetric. Because most of chafing dish enthusiasts love the spicy bottom of a red pot, the number of people who often eat the clear soup side of the mandarin duck pot is obviously less than that of people who eat the clear soup side of the red pot, so that the bottom of the red pot is insufficient, and the bottom of the clear soup pot is excessive. In view of this, another primary-secondary pot has come into existence, that is, a cylindrical metal tube is welded in the pot, so that the interior of the metal tube is used for containing clear soup, namely a secondary pot; the space between the metal tube and the pot is used for containing the red soup, namely the mother pot. Therefore, the required proportion of the clear soup to the red soup can be met; if fewer people like the spicy red soup pot bottom in northern areas, the clear soup/red soup in the primary pot and the secondary pot can be exchanged, the primary pot is used for containing the red soup pot bottom, and the secondary pot is used for containing the clear soup pot bottom, so that the taste requirements of people can be met.

Although the proportion demand of people's taste can be satisfied to the pan that adopts above-mentioned current pan, but in the in-service use has a very obvious and technical problem who reduces the practicality. Problem 1: when heating, the stock in the mother pot is heated boiling very soon, but the stock in the son pot can't boil the boiling all the time, especially adopts the electromagnetism stove heating methods of low carbon environmental protection, adopts the tube-shape primary and secondary pot to be difficult to more let the stock juice in the son pot boil, and this lets the visitor latency can prolong a lot. Because of the technical problems that the heating is slow and the heating cannot be synchronous and uniform, the practical application effect of the conventional primary and secondary pots is not good, and only because no new product is updated and iterated, the chafing dish shops on the market still adopt the two pots. Problem 2: two sets of pots can be arranged in an existing hot pot shop according to the number of tables, namely each table is provided with a pot with a single taste and a pot with double tastes (namely a pot with dual purposes of red soup and clear soup), a primary pot and a secondary pot can be adopted, and a double-taste pot can also be adopted. This just leads to the pan input cost of chafing dish shop to multiply, and it is also very big to the pan storage pressure in the shop simultaneously, especially mandarin duck pot can't overlap and place, very occupation space.

In order to solve the technical problems, a detachable double-taste pot is needed, the double-taste pot can be switched between the double-taste pot and a single-taste pot at any time according to needs, and for a hot pot restaurant, only one pot needs to be equipped for each table, so that the stock pressure is reduced; meanwhile, the pan is not affected by heat, and the problems that the traditional primary and secondary pans are not uniformly heated and the secondary pans are not easy to boil are solved.

SUMMERY OF THE UTILITY MODEL

The problems that the primary pot and the secondary pot in the prior art cannot be detached, and the boiling time of the primary pot and the boiling time of the secondary pot are inconsistent when the primary pot and the secondary pot are heated, so that the dining waiting time is long are solved; especially, under the condition of adopting the heating mode of the induction cooker, the time period of the boiling of the sub-pot is further prolonged, and the dining time cost of the eaters is greatly wasted. The application provides a magnetic detachable primary-secondary mandarin duck pot which is used for meeting the requirement that a primary-secondary pot can be switched between a single-flavor soup material and two flavor soup materials at will, so that the cost investment of a hot pot shop or a soup pot shop on a pot and the stock pressure are reduced; more importantly, the primary and secondary pots which are connected by magnetic adsorption can well solve the problem that soup in the secondary pot is not easy to boil by adopting an electromagnetic oven heating mode. The utility model provides a primary and secondary pot can be easily dismantled to magnetic force, does not have physical connection structure each other, is convenient for install, dismantles and washs, does not have clean dead angle. Simultaneously, the primary and secondary pot can be dismantled to magnetic force in this application can be suitable for the heating of current electromagnetism stove on the market, can realize that the soup base in primary and secondary pot reaches the technological effect of synchronous boiling under the condition of the same high liquid level basically, has avoided current primary and secondary pot to adopt the electromagnetism stove heating method with the problem that the heating of secondary pot soup base is long-consuming time.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:

the utility model provides a primary and secondary mandarin duck pot can be dismantled to magnetic force, includes female pot, installs the son pot of bottom in the female pot, son pot passes through magnetic force and adsorbs the interior bottom of female pot, the contact surface of female pot and son pot is laminated each other.

Preferably, in order to better realize the detachability and the installation, a magnetic force sheet connected through magnetic force adsorption is further arranged between the main pot and the sub-pot. The magnetic force piece can be an independent plate material, and the main pot and the sub-pot are adsorbed together by the magnetic force of the magnetic force piece so as to achieve the relative fixation of the sub-pot and the main pot.

In order to better heat the sub-pot and the main pot simultaneously in an induction cooker heating mode, the magnetic force sheet is fixedly connected with the bottom of the sub-pot coaxially. With magnetic force piece and sub-pot interconnect together can further simplify the physical structure of primary and secondary pot, can further promote the convenient degree of installation and dismantlement, when actual installation, only need the operation of eyesight adsorb the sub-pot in the bottom center of female pot can. It is worth to be noted that although the magnetic pieces are fixedly connected with the bottom of the sub-pan, the magnetic pieces cannot be omitted, and meanwhile, the bottom of the sub-pan cannot be directly magnetized through repeated experiments of the applicant; the reason is that the diameter of the electromagnetic coil of the universal main stream electromagnetic oven sold in the market and the size of the conventional primary-secondary pot are taken as samples, the diameter of the bottom of the secondary pot accounts for 60-80% of the diameter of the electromagnetic coil, if the electromagnetic coil is installed in a mode of directly magnetizing the bottom of the secondary pot, the secondary pot is magnetized and adsorbed at the inner bottom of the primary pot, then tap water is contained and placed on the electromagnetic oven, the power of the electromagnetic oven is set to be not less than 1500w, and after 16 minutes, the tap water in the secondary pot can be seen to obviously turn over and boil at first; however, at the moment, tap water with the same liquid level in the mother pot has no sign of overturning, and the only visible phenomenon is that a plurality of fine bubbles are attached to the position, close to the bottom, of the mother pot, and the bubbles do not separate from the mother pot.

In the same way, under the condition that other conditions are not changed, the diameter of the sub-pot is reduced by 50 percent, tap water with the same liquid level height is continuously heated by an induction cooker with the same power of 1500 w; after minutes, tap water in the sub-boiler and the main boiler does not boil, and tiny bubbles are attached to the bottoms of the inner walls of the sub-boiler and the main boiler, so that the bubbles are basically free from separation.

From the above, the heating speed of the sub-pan is positively correlated with the magnetized sub-pan bottom. If the bottom of the sub-pot is directly magnetized, and the sub-pot and the main pot are almost synchronously boiled, the sub-pot needs to be obviously reduced, but the cooking practicability of the sub-pot and the main pot is lost; if the basic cooking condition of the sub-boiler is met, the sub-boiler needs to be enlarged, and the sub-boiler occupies most eddy current generated by the electromagnetic coil of the induction cooker, so that the main boiler is directly heated insufficiently and cannot be boiled synchronously.

In view of this, in order to further improve the practicability of the present application, the present electromagnetic oven is compatible to the greatest extent; meanwhile, the technical effect that the soup in the sub-pot and the soup in the main pot are boiled basically and synchronously is achieved, and the size limitation of the magnetic force sheet is very necessary.

Preferably, the diameter of the magnetic sheet is 60-85 mm. In order to more accurately match the ratio of the soup contained in the sub-pot 3 and the main pot 1, the diameter of the magnetic force sheet is 70-80 mm.

For more accurate installation son pot and female pot, the one side centre of a circle department that magnetic force piece is close to female pot is provided with the concave point, the interior bottom centre of a circle of female pot or geometric center department be provided with the bump that the concave point corresponds. In actual installation, because the sub-pan and the main pan can not be concentrically aligned by visual operation, the structure can realize accurate blind operation; when the salient point that sets up on the concave point on the magnetic force piece and the female pot fails to align, son pot and female pot can not laminate, make a round trip to rock son pot, when the salient point that sets up on concave point on the magnetic force piece and the female pot aligns, son pot and female pot laminate completely to under the effect of magnetic force absorption, son pot and female pot adhesion form an organic whole structure together. At the moment, the sub-pan and the main pan are concentrically arranged and placed on the induction cooker for heating, and the maximum effect of magnetic heat generation can be realized.

In order to prolong the magnetic force effect of magnetic force piece promotes magnetic strength, reduces the thermal decay of magnetic force, the magnetic force piece adopts the neodymium iron boron material that has the metal coating to make. The metal coating can adopt zinc plating, nickel plating or copper plating and the like, which is beneficial to protection and improves the corrosion resistance and the wear resistance; meanwhile, a metal coating which is beneficial to welding can also be adopted.

In order to further optimize the magnetic force performance of the magnetic force sheet, the magnetizing direction of the magnetic force sheet is axial magnetizing.

Example 1:

combine specification attached figure 1-6 to show a primary and secondary mandarin duck pot can be dismantled to magnetic force, including female pot 1, install the son pot 3 of bottom in female pot 1, son pot 3 passes through magnetic force and adsorbs the interior bottom of female pot 1, the contact surface of female pot 1 and son pot 3 laminates each other. The maximum clearance of the binding face of the mother pot 1 and the son pot 3 is less than 0.1mm, and a magnetic force sheet 2 connected through magnetic force adsorption is further arranged between the mother pot 1 and the son pot 3. The magnetic force sheet 2 is an independent plate material, and the main pot 1 and the sub-pot 3 are mutually adsorbed together through the magnetic force of the magnetic force sheet 2 per se so as to achieve the relative fixation of the sub-pot 3 and the main pot 1.

The working principle is as follows:

the main pot 1 is placed on a heating panel of the induction cooker, the induction cooker is opened, an electromagnetic coil 4 of the induction cooker generates countless magnetic induction lines 5 under the action of current, the magnetic induction lines 5 penetrate through the bottoms of the main pot 1 and the sub-pot 3 which are placed on the heating panel of the induction cooker, eddy currents 6 are formed at the bottoms of the main pot 1 and the sub-pot 3, the bottoms of the sub-pot 3 and the main pot 1 are continuously heated, and soup contained in the sub-pot 3 and the main pot 1 is heated until boiling. Because the sub-pan 3 is positioned in the center of the electromagnetic coil 4, the magnetic induction lines 5 generated by the electromagnetic coil 4 are positioned in the sub-pan 3, the eddy currents are less, the magnetic induction lines 5 are relatively dispersed, and more eddy currents 6 are generated in the main pan 1, so that when the conventional electromagnetic oven heats the sub-pan and the main pan, the boiling time period of the sub-pan 3 is obviously longer than that of the main pan 1. This embodiment is through adding magnetic force piece 2 between son pot 3 and mother pot 1, under the effect of magnetic force piece 2, magnetic induction line 5 that solenoid 4 produced can concentrate and pass magnetic force piece 2 under the effect of magnetic force piece 2, make 6 more concentrated at the vortex that 3 bottoms of son pot produced, thereby make 3 intensification of son pot faster, thereby make 3 boiling time of son pot obviously shorten, realize the uniformity of son pot 3 and mother pot 1 boiling time through the size of adjusting magnetic force piece 2. The embodiment is based on the energy conservation principle, the magnetic force sheet 2 is creatively arranged to change the scientific distribution of the magnetic induction lines 5 generated by the electromagnetic coil 4 between the sub-pot 3 and the main pot 1, so that the convergence degree of the eddy current 6 between the sub-pot 3 and the main pot 1 is changed. Fig. 5 shows a state of magnetic induction lines 5 of a conventional induction cooker heating pot, and fig. 6 shows a state of gathering the magnetic induction lines 5 by the magnetic sheet 2; when the ratio of the vortex 6 obtained by the sub-boiler 3 and the mother boiler 1 is equal to the heat required by the boiling of the soup in the sub-boiler 3 and the mother boiler 1, the soup in the sub-boiler 3 and the mother boiler 1 can be easily boiled at the same time. Through repeated experiments of an applicant, the liquid levels of the soup in the sub-pot 3 and the main pot 1 are adjusted to be different, no matter the liquid level of the sub-pot 3 is higher than that of the main pot 1, or the liquid level of the main pot 1 is slightly higher than that of the sub-pot 3, on the premise that the magnetic sheet 2 is not added, the boiling phenomenon of the sub-pot 3 is obviously later than that of the main pot 1 all the time, and when the main pot 1 boils for 5 minutes, the sub-pot 3 does not have the visible boiling phenomenon. Similarly, when the applicant adds the magnetic sheet 2, the liquid level height between the main pot 1 and the sub-pot 3 is adjusted again, and no matter whether the liquid level of the sub-pot 3 is higher than the liquid level of the main pot 1 or the liquid level of the main pot 1 is slightly higher than the liquid level of the sub-pot 3, although the boiling time is slightly out and in, the time difference basically does not exceed 3 minutes, and the boiling time tends to be synchronous. Therefore, the magnetic induction lines 5 are more gathered in the sub-pots 3 by the direct action of the magnetic force sheets 2 on the magnetic induction lines 5 and the indirect action of the generated vortex 6, so that the required boiling time of the sub-pots 3 is shorter, and the decisive effect is achieved.

Example 2:

on the basis of embodiment 1, as shown in fig. 1-4 and fig. 6 of the specification, in order to adapt to the current commercial electromagnetic oven and increase the utility of the present invention, the present embodiment, on the basis of embodiment 1, fixedly connects the magnetic force sheet 2 and the bottom of the sub-pan 3 coaxially. And the diameter of the magnetic sheet 2 is 80 mm. Because the average diameter of the electromagnetic coil of the existing induction cooker is about 200mm, when the induction cooker is heated by adopting the magnetic force sheet 2 with the diameter of 80mm, the magnetic induction lines 5 generated by the induction cooker, namely the heating eddy current 6, can be more uniformly distributed, so that the technical effect that the primary and secondary pots can realize the basic synchronous boiling of the primary pot 3 and the secondary pot 1 when the primary and secondary pots are heated on the induction cooker purchased at any time in the market can be realized. To verify that setting the diameter of the magnetic sheet 2 to 80mm is the preferred size, in this example, the applicant conducted the following experiment:

the applicant purchases 4 induction cookers with different sizes and models to respectively heat the primary and secondary pots filled with tap water with the same temperature and volume, and the primary and secondary pots are sequentially placed on 4 induction cookers to be continuously heated with different powers, and the results are as follows:

firstly, normal-temperature tap water is filled into the primary pot and the secondary pot, when the liquid levels in the primary pot 3 and the secondary pot 1 are basically the same, a mark is made on the liquid level by using a mark pen, then a scratch mark is made on the marked liquid level of the mark by using an art designing knife along the liquid level, and the mark of the mark by the mark pen is prevented from being fuzzy due to heating.

A first group: american electromagnetic oven, model C22-WT2203, maximum output power 2200W;

second group: a Supor brand induction cooker, model SDHC8E15-210D, with a maximum output power of 2200W;

third group: jiuyang electromagnetic oven, model JYC-21HEC05, with maximum output power of 2100W;

and a fourth group: the glorious electromagnetic oven has the model number WL01T and the maximum output power 2200W;

adopt above-mentioned 4 electromagnetism stoves of different brands and model to the same primary and secondary pot splendid attire tap water of the same initial temperature with different power respectively the heating, specifically do:

the first group of rated heating power is 1000W, the boiling phenomenon of water in the primary pot 1 can be seen visually after 24 minutes, and the boiling phenomenon of water in the secondary pot 3 can be seen visually after 2 minutes and 25 seconds;

the rated heating power of the second group is 1500W, the boiling phenomenon of the water in the primary pot 1 can be seen visually after 19 minutes and 15 seconds, and the boiling phenomenon of the water in the secondary pot 3 can be seen visually after 1 minute and 51 seconds;

the third group of rated heating power is 1800W, the boiling phenomenon of the water in the primary pot 1 can be seen visually after 15 minutes and 45 seconds, and the boiling phenomenon of the water in the secondary pot 3 can be seen visually after 0 minutes and 55 seconds;

the third group of rated heating power is 2000W, the boiling phenomenon is firstly visible for the son pot 3 after 13 minutes and 28 seconds, then the boiling phenomenon is visible for the first minute and 20 seconds, bubbles in the mother pot 1 gradually grow and separate, and the boiling phenomenon is visible for the first minute and 20 seconds;

from the above, when the diameter of the magnetic force plate 2 is set to 80mm, the electromagnetic oven can meet the current mainstream commercial electromagnetic oven products, so that the boiling time is obviously superior to that of the existing primary and secondary pots under the condition of the same liquid level in the primary pot 1 and the secondary pot 3, although the soup contained in the primary pot 1 and the secondary pot 3 may be inconsistent and the ingredients of the soup have slight difference when the chafing dish or the soup pot is actually cooked, the boiling time difference of the primary pot 1 and the secondary pot 3 is basically kept about 2 minutes, and the technical effect obtained by heating the existing primary and secondary pots on the electromagnetic oven is obviously superior.

Simultaneously, this embodiment is for further solving the problem of quick installation, magnetic force piece 2 is provided with the concave point near one side centre of a circle of female pot 1, the interior bottom centre of a circle of female pot 1 or geometric center department be provided with the bump that the concave point corresponds. In actual installation, because the sub-pan 3 and the main pan 1 can not be concentrically aligned by visual operation, the structure arrangement can realize accurate blind operation; when the salient point that sets up on the concave point on the magnetic force piece 2 and the female pot 1 fails to align, son pot 3 and female pot 1 can not laminate, make a round trip to rock son pot 3, when the salient point that sets up on concave point on the magnetic force piece 2 and the female pot 1 aligns, son pot 3 and female pot 1 laminate completely to under the effect of magnetic force absorption, son pot 3 and the adhesion of female pot 1 form an organic whole structure together. At the moment, the sub-pot 3 and the main pot 1 are concentrically arranged and placed on an induction cooker for heating, and the maximum effect of magnetic heat generation can be realized.

In order to prolong the magnetic force effect of magnetic force piece 2 promotes magnetic strength, reduces the thermal decay of magnetic force, magnetic force piece 2 adopts the neodymium iron boron material that has metal coating to make. The metal coating can adopt zinc plating, nickel plating or copper plating and the like, which is beneficial to protection and improves the corrosion resistance and the wear resistance; meanwhile, a metal coating which is beneficial to welding can also be adopted.

In order to further optimize the magnetic performance of the magnetic sheets 2, the magnetizing direction of the magnetic sheets 2 is axial magnetizing.

In order to better heat 3 and the mother pot 1 simultaneously through electromagnetism stove heating methods, can further simplify the physical structure of primary and secondary pot with 2 and 3 mutual fixed connection of son pot, can further promote the convenient degree of installation and dismantlement together, when actual installation, only need look the operation with son pot 3 adsorb in the bottom center of mother pot 1 can.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art.
