Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature devices, in particular to a constant temperature device with uniform heat reception. Background Technique

[0002] A constant temperature device is a device that directly or indirectly controls one or more heat sources and cold sources to maintain the required temperature. To achieve this function, a thermostat must have a sensitive element and a converter. The sensitive element measures the change in temperature and exerts the required effect on the converter. The converter converts the effect from the sensitive element into an effect that can properly control the device for changing the temperature.

[0003] The existing constant temperature devices generally heat by directly installing heating elements inside the constant temperature cavity and keep warm after reaching the required temperature. When the constant temperature cavity is relatively large, the temperature inside may be uneven, that is, the temperature at one end close to the heating element is relatively high, and the temperature at the end far from the heating element is relatively low, which is difficult to meet the actual use requirements. Summary of the Invention

[0004] The purpose of the utility model is to provide a constant temperature device with uniform heat reception to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A constant temperature device with uniform heat reception, including a constant temperature cavity, a heating element installed inside the constant temperature cavity, and a movable door that can be opened and closed and installed on the front end face of the constant temperature cavity. A fan is installed inside the constant temperature cavity through a mounting plate. A ventilation and cooling mechanism is arranged inside the constant temperature cavity, and the ventilation and cooling mechanism includes a plurality of first ventilation holes arranged on the side wall of the constant temperature cavity and a baffle that is movably arranged up and down inside the first ventilation holes through a linear driving member. The baffle is used to block the first ventilation holes, and a plurality of second ventilation holes corresponding to the first ventilation holes one by one are penetrated through the baffle.

[0006] Furthermore, a plurality of placement grooves are arranged inside the constant temperature cavity.

[0007] Furthermore, a plurality of through holes are penetrated through the side wall of the placement groove.

[0008] Furthermore, a plurality of sliding rods are arranged inside the constant temperature cavity, a plurality of sliding blocks slidably connected to the sliding rods are arranged on the outer peripheral edge of the placement groove, and fasteners are arranged on the sliding blocks.

[0009] Furthermore, the size of the placement groove gradually decreases from top to bottom.

[0010] Furthermore, a temperature sensor is installed inside the constant temperature cavity.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The uniformly heated constant temperature device installs a heating element and a fan inside the constant temperature chamber. The heating element heats up, and the fan drives the air flow inside the constant temperature chamber, enabling the temperature to be the same everywhere inside the constant temperature chamber. By setting up a ventilation and cooling mechanism inside the constant temperature chamber, when the temperature inside the constant temperature chamber exceeds the threshold value, the fan can draw cold air from the outside into the constant temperature chamber for cooling, making the temperature control more precise;

[0013] By installing a storage slot inside the constant temperature chamber, multiple items can be placed. By setting up sliding rods and fasteners, the layer height can be adjusted according to the product needs. At the same time, a spacing is reserved between the outer peripheral edge of the storage slot and the inner side wall of the constant temperature chamber to facilitate air flow and ensure that the temperature is the same everywhere inside the constant temperature chamber.

[0020] Please refer to Figures 1-3 , an embodiment provided by the present utility model: a constant temperature device with uniform heat absorption, comprising a constant temperature chamber 1, a heating element 2 installed inside the constant temperature chamber 1, and a movable door 9 that can be opened and closed and installed on the front end face of the constant temperature chamber 1. A fan 4 is installed inside the constant temperature chamber 1 through a mounting plate 3. In this embodiment, the heating element 2 may specifically be an electric heating tube, which is installed on the back inside the constant temperature chamber 1. The mounting plate 3 is installed in front of the heating element 2. A number of ventilation holes are provided through the mounting plate 3. By heating with the heating element 2, the temperature inside the constant temperature chamber 1 is increased, and the fan 4 drives the flow of the internal air, making the temperature everywhere inside the constant temperature chamber 1 consistent. A temperature sensor is installed inside the constant temperature chamber 1 to monitor the temperature inside the constant temperature chamber 1.

[0021] Inside the constant temperature chamber 1, a ventilation and cooling mechanism 8 is provided. In this embodiment, the ventilation and cooling mechanism 8 includes a number of first ventilation holes 801 provided on the back of the constant temperature chamber 1 and a baffle 802 that is movably arranged up and down inside the first ventilation holes 801 by a linear drive member 804. The baffle 802 is used to block the first ventilation holes 801, and a number of second ventilation holes 803 corresponding to the first ventilation holes 801 one by one are penetrated through the baffle 802. The first ventilation holes 801 and the second ventilation holes 803 are of the same size and are all strip-shaped through holes arranged at equal intervals from top to bottom. The distance between adjacent two strip-shaped through holes is greater than the width of the strip-shaped through holes. The linear drive member 804 can specifically be an electric telescopic rod, which is installed on the back of the mounting plate 3 through a support plate, and its output end is fixedly connected to the bottom end of the baffle 802 through the support plate. By the telescopic movement of the linear drive member 804, the up and down movement of the baffle 802 is driven. When the first ventilation holes 801 and the second ventilation holes 803 coincide, the cold air outside can be drawn into the inside of the constant temperature chamber 1 for cooling. When the first ventilation holes 801 and the second ventilation holes 803 are completely separated, the inside of the constant temperature chamber 1 can be made into a closed space to reduce heat loss. Further, in order to improve the stability of the movement of the baffle 802, the baffle 802 can specifically be slidably arranged on the back inside the constant temperature chamber 1 through a slide rail. Filter meshes are provided on the first ventilation holes 801 and the second ventilation holes 803 to prevent dust and sundries from entering the inside of the constant temperature chamber 1.

[0022] In this embodiment, a number of storage slots 6 are provided inside the constant temperature chamber 1, and different items can be placed in layers. A number of through holes 601 are penetrated through the side walls of the storage slots 6 to facilitate the flow of air between the storage slots 6.

[0023] In this embodiment, sliding rods 5 are respectively arranged at the four corners inside the constant temperature chamber 1, and all four sliding rods 5 are located at the front end of the mounting plate 3. A number of sliders 602 slidably connected to the sliding rods 5 are arranged on the outer peripheral edge of the storage slot 6. A fastening member 7 is arranged on the slider 602. The fastening member 7 can specifically be a bolt threadedly connected to the slider 602. By sliding the storage slot 6 up and down, the layer height can be adjusted according to the height of the placed items, and by rotating the fastening member 7, it can be fixed to meet different constant temperature storage requirements. By providing the sliding rods 5, the distance between the outer peripheral edge of the storage slot 6 and the inner side wall of the constant temperature chamber 1 can be reserved at the same time to facilitate the flow of air and avoid inconsistent temperatures of each layer, further ensuring the uniformity of the temperature inside the constant temperature chamber 1.

[0024] In this embodiment, the size of the storage slot 6 gradually decreases from top to bottom, and multiple unused storage slots 6 can be stacked and stored to reduce the occupied space.

[0025] Further, the constant temperature device with uniform heat reception further includes a controller. The output end of the temperature sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input ends of the heating element 2, the fan 4, and the linear driving member 804, enabling intelligent control of the operation of each component.

[0026] Working principle: During use, the first ventilation hole 801 and the second ventilation hole 803 are mutually misaligned, and the baffle 802 shields and seals the first ventilation hole 801. Place the item inside the storage slot 6, heat it through the heating element 2, and the fan 4 drives the air flow to make the temperature consistent everywhere inside the constant temperature chamber 1. When the temperature in the constant temperature chamber 1 exceeds the threshold value, the linear driving member 804 contracts to push the baffle 802 upward. At this time, the second ventilation hole 803 coincides with the first ventilation hole 801, making the constant temperature chamber 1 communicate with the outside. The fan 4 can draw in the cold air from the outside to cool the inside. When the set temperature is reached, the linear driving member 804 extends to push the baffle 802 downward to shield the first ventilation hole 801. Loosen the fastener 7 and slide the storage slot 6 up and down to adjust the layer height according to the height of the item. After adjustment, rotate the fastener 7 to fix the storage slot 6.

[0027] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model.
