The present invention relates to a dual case for temperature control, and more particularly, to a case used to allow the ambient temperature of a sensor, that is, the odor sensor, used in the odor generating measuring apparatus to be kept constant without being influenced by the outside.

Odor generation detection systems that collect odors and generate alarms in areas where odors occur, such as food waste treatment plants, sewage treatment plants, and factories, are widely used.

In order to establish effective prevention measures by immediately identifying and tracking the cause of odor occurrence, such a odor occurrence measuring device is installed in a place where odor occurrence is expected.

Such odors are more severely generated especially at high external temperatures such as in summer, and therefore, the necessity of using the odor measurement device is increased in summer.

However, a sensor such as a odor sensor installed in the odor generating measuring device reacts very sensitively to the temperature around the sensor. In particular, when the outside temperature is high, the temperature around the sensor is also a high temperature, a problem occurs that the sensor malfunctions or does not properly function. In addition, the same problem may occur when the outside temperature is low, such as winter.

Therefore, it is important to ensure that the ambient temperature has less influence on the sensor, especially that the sensor can operate without being affected by the temperature, especially when the ambient temperature is too high, such as in summer, or when the ambient temperature is too low, such as in winter. Necessity arises. That is, the temperature around the sensor should be maintained within the temperature range in which the sensor can operate normally, so that the odor generating measuring device can operate normally.

Therefore, the present inventors have developed a case in which the sensor installed in the odor generating measuring device is not affected by external temperature.

The present invention aims at keeping the temperature of the sensor, especially the odor detector constant, by blocking the influence of external temperature in order to solve the above problems.

Another object of the present invention is to block radiant heat such as direct sunlight from the sun.

Dual case for temperature control according to the present invention and the inner housing surrounding the odor generating measuring device; It is arranged to form an air gap of a predetermined interval between the outer surface of the inner housing from the outside of the inner housing, and has an air inlet for introducing external air at one end, and discharges the introduced external air at the other end An outer housing provided with an air outlet; And a fan for blowing air introduced into the air inlet of the outer housing through the air gap. As the air passes through the air gap, which is an empty space formed between the side of the inner housing and the side of the outer housing, an air curtain surrounding the inner housing is formed to block external heat from entering.

The outer housing may be preferably coated with a heat shield that can block radiant heat. By blocking direct sunlight, such as sunlight, it is possible to reduce the range in which the internal temperature rises.

In addition, the double case may further include a heater for heating the malodor generating measuring device. When the ambient temperature is very low, such as in winter, the heater heats the odor generating measuring device, thereby minimizing the influence of cold outside air.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a double case for temperature control surrounding the malodor generating measuring device and the malodor generating measuring apparatus according to the present invention is shown. Specifically, on the left side of FIG. 1, a malodor generating measuring apparatus 100 including a malodor detector 101 and a malodor collector 102 is illustrated. On the right side of Figure 1 is shown a dual case 10 for temperature control according to the present invention surrounding the odor generating device 100 is located therein.

2 is an enlarged front view of the double case 10 of FIG. 1, and FIG. 3 is a right side view thereof. Dual case 10 for temperature control according to the present invention is composed of an inner housing 20 and the outer housing 30, the side of the outer housing 30 is spaced apart from the side of the inner housing 20 at a predetermined interval The state surrounds the inner housing. In addition, the upper portion of the inner housing may be spaced apart from the upper portion of the outer housing so that the fan 40, which will be described later, is positioned on the upper side in the outer housing.

The inner housing 20 is in the form of a cube and surrounds the entire odor generating measuring device 100, and the inner housing 20 is surrounded by a cube-shaped outer housing 30. The outer housing 30 may be open on one side, in particular on the lower side in the example shown in the figures. Air may be discharged through the open surface as described below. However, it should be noted that the configuration for discharging air is not limited thereto, and an outlet may be formed instead of opening one side.

The inner housing 20 is spaced apart from each other by the outer housing 30 and its side, and are connected to each other by a fastening device such as a plurality of bolts and nuts on the side of the inner and outer housing. Thus, an empty space, ie an air gap, is formed between the sides of the inner housing and the sides of the outer housing, ie surrounding the outer side of the inner housing. When viewed from above, this air gap will have the shape of a rectangular ring in cross section. An empty space, ie, an air gap, becomes a place where air passes downward as described later.

In the upper side of the outer housing, specifically, between the top of the outer housing and the top of the inner housing, a fan 40 for sucking air and letting it downward is provided. In addition, one side of the upper side of the outer housing is provided with an air inlet 31 so that air is introduced into the interior at a higher position than the top of the inner housing.

By operating the fan, air is introduced into the outer housing 30 through the inlet 31 in the direction of the arrow A shown in FIGS. 1 and 2, and the introduced air is supplied to the inner housing 20 and the outer housing ( Passed downward through the air gap, an empty space formed between the sides of the 30). The air passing through this empty space is finally discharged to the outside through the outlet in the direction indicated by arrow B, preferably through the open part of the lower part of the outer housing.

The sensor of the odor generating measuring device, that is, the odor detector, is affected by temperature. That is, the sensor can operate normally only in a temperature range that is not too high.

If the ambient temperature is high, such as in summer, it is necessary to keep the temperature around the sensor constant. To this end, using the double case according to the present invention, the air introduced into the double case through the air inlet 31 of the outer housing 30 as described above is between the outer housing and the inner housing by the fan 40 It is moved downward through the space formed in the state is made to be continuously discharged through the outlet of the lower.

If the outside temperature is very low, such as winter, the heater may be installed in the upper space inside the outer housing. The hot air generated by the heater can be moved through an air gap formed between the outer housing and the side of the inner housing described above.

The flow of air flowing downward in the air gap serves as a kind of air curtain to block external heat or cold air. That is, when the air layer flowing downward continuously through the air gap formed on the sides of the outer housing and the inner housing is heat from the outside when the outside is high temperature, such as in summer, or the outside cold air when the outside is low temperature, such as in winter, measurement of odor occurrence Blocking transmission to the inside of the device. Therefore, the temperature around the odor detector inside the odor generating measuring apparatus can be maintained in an appropriate range without being influenced by the external temperature.

In addition, in order to block radiant heat, it is preferable that the outer housing uses a housing coated with a paint such as heat shield paint.

The present invention, in summer, the air introduced by the fan can pass through the empty space formed by the outer housing and the inner housing to prevent the heat from being introduced from the outside, and in winter, the outside by the hot air formed by the heater It is possible to reduce the effect of low temperature on the sensor of the odor generating measuring device. Therefore, the odor detector can operate normally without being affected by the outside temperature.

In addition, by configuring an outer housing for the radiant heat blocking housing that can block the radiant heat, there is an effect that can further block the inflow of heat.

The above description is only a preferred embodiment of the present invention, the present invention is not limited to the above-described embodiment. For example, the structure and shape and arrangement of components such as inlets, outlets and fans can vary. It should be noted that those skilled in the art can make various modifications without departing from the spirit of the claims, and such modifications fall within the scope of the claims.
