Description

Technical Field

[0001] The utility model relates to the technical field of stove testing, in particular to a stove performance testing device. Background Art

[0002] When existing stove manufacturers launch a new stove product, they need to conduct durability tests on the life of the stove to check whether the quality is up to standard. For details, please refer to the Chinese patent application number CN201820583514.8 previously applied by the applicant, "A stove performance testing device".

[0003] According to the durability requirements of GB16410-2020 "Household Gas Cookers", the number of actions of key parts of gas stoves must meet the requirements of the standard, and the airtightness must meet the requirements without hindering use. In order to verify the durability of the gas stove, it is necessary to conduct a life test on the entire product. The entire machine is continuously heated and the pot is in place. Therefore, during the life test of the entire machine, water needs to be continuously added to the pot on the entire machine to fully ensure safe and continuous combustion. The specific operation method is: the temperature of the bottom of the pot is detected by the sensor, and when it reaches a certain temperature limit, water is automatically added to the pot.

[0004] However, in the above scheme, on the one hand, water needs to be added repeatedly, and there is a risk of sensor failure. Once it fails, the empty pot will burn, which poses a great hidden danger. On the other hand, the water pot will generate a large amount of steam during the durability test, which will accelerate the oxidation of other adjacent equipment. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a stove performance testing device capable of avoiding repeated water addition and reducing the oxidation of the equipment by water vapor in view of the current status of the prior art.

[0006] The utility model solves the above technical problems by adopting the following technical solution: a stove performance testing device, comprising:

[0007] A countertop for placing the cooker; and

[0008] A pot, used to be placed on the burner of the stove;

[0009] It is characterized in that: the cookware comprises

[0010] a metal plate for resting on the burner of the cooker; and

[0011] A plurality of heat dissipation columns are arranged at intervals on the surface of the metal plate, and each heat dissipation column is thermally connected to the metal plate.

[0012] In order to facilitate the testers to evaluate the flame uniformity of the stove and realize the high temperature warning function of the pot body, a temperature sensor is installed at the position of each heat dissipation column close to the metal plate.

[0013] In order to facilitate monitoring of the temperature at various positions of the metal disk, the metal disk is a circular disk, and the heat dissipation columns are arranged in groups. The heat dissipation columns of the latter group are arranged at intervals on the outer periphery of the heat dissipation columns of the former group. In each group of heat dissipation columns, the heat dissipation columns are arranged at intervals along the circumference of the metal disk.

[0014] In order to realize the automatic placement and taking-out of the pot and the automatic pot lifting function, a lifting rod for driving the pot to be lifted up and down is also included.

[0015] In order to realize automatic control, the stove performance testing device has a controller, and the temperature sensor and the lifting rod are electrically connected to the controller, so that the controller can receive the signal collected by the temperature sensor and control the lifting rod to drive the pot to rise and fall.

[0016] In order to adjust the fire power and achieve cooling according to the temperature rise of the stove surface, it also includes

[0017] An infrared temperature recorder, used to monitor the temperature rise on the surface of the cooker;

[0018] A manipulator for turning a knob of the cooker; and

[0019] The spray head is used for spraying cooling water onto the glass panel of the cooker.

[0020] In order to realize automatic control, the stove performance testing device has a controller, and the infrared temperature recorder, manipulator and spray head are electrically connected to the controller, so that the controller can receive the signal collected by the infrared temperature recorder and control the manipulator to turn the knob of the stove and control the opening and closing of the spray head.

[0021] In order to further improve the heat dissipation effect, the cookware also includes a heat dissipating plate, which is thermally connected to each of the heat dissipating columns.

[0022] In order to improve the uniform heat effect, there are multiple heat-uniform plates, which are arranged at intervals along the axial direction of the heat dissipation column.

[0023] In order to facilitate the thermal connection between the heat dissipating plate and each heat dissipating column, each heat dissipating plate is provided with a plurality of sockets corresponding to the heat dissipating columns, each heat dissipating column is inserted into the corresponding socket, and the outer peripheral wall of the heat dissipating column is in thermal contact with the inner peripheral wall of the corresponding socket.

[0024] Compared with the prior art, the utility model has the advantages that the cooker is composed of a metal plate and a plurality of heat dissipation columns arranged at intervals on the surface of the metal plate. Since the heat dissipation columns are thermally connected to the metal plate, during the combustion process, the metal plate dissipates heat through the heat dissipation columns to achieve thermal balance, thereby avoiding repeated addition of water and reducing the oxidation of the equipment by water vapor.

[0030] Embodiment 1:

[0031] like Figure 1 to Figure 2 The figure shows the first preferred embodiment of the stove performance test device of the utility model. The stove performance test device comprises a table 1, a pot 2, a lifting rod 3, an infrared temperature recorder 4, a manipulator 5 and a spray head 6.

[0032] The table top 1 is used for placing a stove 10 .

[0033] The pot 2 is used to be placed on the burner of the stove 10. In this embodiment, the pot 2 includes a metal plate 21 and a heat dissipation column 22.

[0034] Specifically, the metal plate 21 is a circular plate made of aluminum material and is used to be placed on the burner of the stove 10;

[0035] There are multiple heat dissipation columns 22, which are erected in groups on the surface of the metal disk 21. The heat dissipation columns 22 of the latter group are arranged at intervals on the outer periphery of the heat dissipation columns 22 of the former group. In each group of heat dissipation columns 22, the heat dissipation columns 22 are arranged at intervals along the circumference of the metal disk 21, and the bottom ends of the heat dissipation columns 22 are thermally connected to the metal disk 21; a temperature sensor 221 is installed at the side of each heat dissipation column 22 near the metal disk 21.

[0036] The lifting rod 3 is installed above the table 1 and is used to drive the pot 2 to rise and fall, thereby realizing the automatic placement and taking of the pot 2 and realizing the automatic pot lifting function.

[0037] The infrared temperature recorder 4 is installed above the table 1 to monitor the temperature rise on the surface of the stove 10 .

[0038] The manipulator 5 is installed above the table 1 and is used to rotate the knob of the stove 10 to control the fire power of the stove 10 burner.

[0039] The spray head 6 is installed above the table top 1 and is used to spray cooling water onto the glass panel of the stove 10 .

[0040] In addition, the stove performance testing device has a controller, and the temperature sensor 221 and the lifting rod 3 are electrically connected to the controller, so that the controller can receive the signal collected by the temperature sensor 221 and control the lifting rod 3 to drive the pot 2 to rise and fall; the infrared temperature recorder 4, the manipulator 5 and the spray head 6 are electrically connected to the controller, so that the controller can receive the signal collected by the infrared temperature recorder 4 and control the manipulator 5 to turn the knob of the stove 10 and control the opening and closing of the spray head 6.

[0041] Embodiment 2:

[0042] like Figure 3 The second preferred embodiment of the stove performance testing device of the utility model is shown in FIG. The difference from the first embodiment is that:

[0043] The cooker 2 further includes a plurality of heat-distributing plates 23 arranged at intervals along the axial direction of the heat-dissipating column 22. Each heat-dissipating plate 23 is provided with a plurality of insertion holes 231 corresponding to the heat-dissipating column 22. Each heat-dissipating column 22 is inserted into a corresponding insertion hole 231, and an outer peripheral wall of the heat-dissipating column 22 is in thermal contact with an inner peripheral wall of the corresponding insertion hole 231, thereby realizing a thermal connection between the heat-dissipating plate 23 and each heat-dissipating column 22.

[0044] Taking Example 1 as an example, the working principle of the present application is as follows: during the test, the stove 10 is placed at the test position of the table 1, and the pot 2 is placed on the burner of the stove 10, and the stove 10 is started to burn:

[0045] During the combustion process, the metal plate 21 dissipates heat through the heat dissipation columns 22 to achieve thermal equilibrium. The temperature sensor 221 monitors the temperature of each heat dissipation column 22 in real time. On the one hand, it is convenient for testers to evaluate the flame uniformity of the cooker 10. On the other hand, when the temperature reaches a critical value, a signal can be transmitted to the controller, and the controller controls the lifting rod 3 to lift the pot 2 to avoid scalding the operator.

[0046] At the same time, the infrared temperature recorder 4 will monitor the temperature rise of the surface of the stove 10 (such as the temperature rise of the glass panel, burner, knob, etc. of the stove 10) in real time. When the temperature rise of a certain component exceeds the standard, the process will be recorded. The temperature rise setting is divided into several stages. An early warning can be given first. When the upper limit is reached, a signal will be transmitted to the controller. The controller controls the manipulator 5 to turn the knob of the stove 10 to automatically turn to a low heat or even turn off the heat to cut off the gas source. If the glass panel of the stove 10 is overheated, a signal will be transmitted to the controller. The controller controls the spray head 6 to start spraying cooling water to the glass panel of the stove 10. On the one hand, timely cooling can be achieved. On the other hand, a hot and cold shock test of the glass panel of the stove 10 can be added to facilitate the evaluation of the reliability of the glass panel of the stove 10.
