Description

  The present invention relates to an apparatus for adjusting the temperature of an automobile, and more particularly to an apparatus for adjusting the temperature of an automobile when riding.

  Conventionally, the temperature of an automobile is usually adjusted by an air conditioner. The air conditioner uses the car battery as a power source to discharge the heat inside the car or supply the heat from outside the car to adjust the temperature inside the car.

However, since the air conditioner uses a battery power source, when parking, if the engine is turned off and the air conditioner continues to operate, the battery will go up, so the air conditioner cannot be used when parking. For this reason, in the summer, the temperature inside the vehicle becomes very high, which is very uncomfortable for those who get on the vehicle when getting on. Also, in winter, it is desirable that the temperature inside the vehicle is higher than the outside of the vehicle when riding, but the air conditioner cannot be operated during parking, so the temperature inside the vehicle becomes the same as the outside air.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make the temperature inside a vehicle moderate when riding without stopping the consumption of energy such as a battery power source when the vehicle engine is stopped and parked.

In order to solve the above problems, the present invention has the following configuration.
The invention according to claim 1 is a device that realizes temperature adjustment with respect to the inside of an automobile in a sealed state, the air intake means for sending air into the vehicle from outside the vehicle, the air intake means, It is a temperature control device for a motor vehicle having a discharge check valve for preventing a backflow of air from the outside of the vehicle to the inside of the vehicle. Note that “to achieve temperature adjustment” includes adjustment of the temperature inside the vehicle in a state of being out of the sealed state. The discharge check valve includes not only a general check valve but also a valve that opens and closes a valve body such as an electromagnetic valve.
According to a second aspect of the present invention, in the temperature control device for an automobile, a measurement unit that measures the atmospheric pressure in the vehicle, and the air suction unit is stopped when the atmospheric pressure measured by the measurement unit reaches a certain value. And automatic stop means.
Invention of Claim 3 is an apparatus which implement | achieves temperature adjustment with respect to the inside of the motor vehicle which became the airtight state, Comprising: The air discharge means which discharges air from the said inside of a vehicle, and the said air discharge means, It is a temperature control apparatus for motor vehicles provided with the suction | inhalation nonreturn valve which prevents the backflow of the air from the said vehicle inside provided in between the said vehicle inside. The suction check valve includes not only a general check valve but also a valve that opens and closes a valve body such as an electromagnetic valve.
According to a fourth aspect of the present invention, there is provided the temperature control device for an automobile, further comprising: a measuring unit that measures the atmospheric pressure in the vehicle; and the air discharge unit in a state where the atmospheric pressure measured by the measuring unit has reached a certain value. And automatic stop means for stopping.
The invention according to claim 5 is an automobile having the automobile temperature control device.
The invention described in claim 6 is an automobile provided with sealing means for opening and closing a vent hole between the inside and outside of the automobile with the window closed and the door closed. The “vent hole” means a hole that communicates between the outside and the inside of the vehicle, which is provided in the design of the automobile, such as an air outlet of an air conditioner.

According to the first aspect of the present invention, when air is fed into the sealed vehicle by air suction means, the pressure inside the vehicle increases. Further, even if the air suction means is stopped by the exhaust check valve, the pressure inside the vehicle can be maintained at a high level. The air inside the vehicle rises in temperature due to the work of the air suction means, but heat escapes to the outside, so that after a while the temperature inside the vehicle becomes the same as the temperature in the normal atmospheric pressure state. When the door is opened in this state, the air inside the vehicle expands at a stretch and is discharged outside. Since the expansion is performed in an instant, the air in the vehicle is almost adiabatically expanded. As a result, the air consumes energy at the time of expansion, and the temperature of the air decreases accordingly, so that the interior of the vehicle when riding can be made more comfortable in the summer. Further, since the air suction means can be stopped when the pressure inside the vehicle becomes high, it does not continue to use energy such as a battery during parking.
According to the second aspect of the present invention, the automatic stop means stops the air suction means when the air pressure is constant, so that the operator can leave the vehicle while operating the air suction means when parking.

In the invention according to claim 3, when the air is discharged from the inside of the automobile in the sealed state by the air discharging means, the atmospheric pressure in the car decreases. Further, even if the air discharge means is stopped by the suction check valve, the pressure inside the vehicle can be kept low. The temperature of the air inside the vehicle is lowered by the work of the air discharge means, but since heat is supplied from the outside, the temperature inside the vehicle becomes the same as the temperature in the normal atmospheric pressure state after a while. In this state, when the door is opened, the air inside the vehicle is compressed by the air flowing in from the outside of the vehicle. Since the inflow is performed instantaneously, the air in the vehicle is almost adiabatically compressed. As a result, the air receives energy at the time of compression, and the temperature of the air rises by that amount, so that the interior of the vehicle when riding can be made more comfortable in winter. Further, since the air discharge means can be stopped when the pressure inside the vehicle becomes low, it does not continue to use energy such as a battery during parking.
According to the fourth aspect of the present invention, since the automatic stop means stops the air discharge means when the air pressure reaches a constant pressure, the operator can leave the vehicle while operating the air discharge means when parking.
According to the fifth aspect of the present invention, since the vehicle temperature control device is provided, it is possible to make the interior of the vehicle a more comfortable temperature when riding without continuously consuming energy such as a battery.
According to the sixth aspect of the present invention, there is provided the temperature control device for an automobile according to the present invention, wherein the sealing means closes or opens the air outlet of the air conditioner as necessary, and does not impair the function of the air conditioner. Can function.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram showing the structure of an automobile Y equipped with an automobile temperature control device X according to this embodiment. The automobile temperature control device X includes an air pump 10, a communication pipe 20, an atmospheric pressure sensor 30, and a control device 40.
The air pump 10 is a general air pump that is driven by a motor, sucks air from an intake port, and discharges air from an exhaust port. By switching a solenoid valve, it is possible to convert intake and exhaust to the communication pipe 20. ing. When the air pump 10 sends air to the communication pipe 20, the air pump 10 constitutes an air suction means. Conversely, when the air pump 10 sends air, the air pump 10 constitutes an air exhaust means.
The communication pipe 20 is a pipe that connects the interior Ya of the automobile Y and the air pump 10, and an electromagnetic valve 21 is provided on the way. The electromagnetic valve 21 cuts off and opens the communication between the communication pipe 20 and the interior Ya. When the air pump 10 performs intake, it constitutes an exhaust check valve, and when the air pump 10 performs exhaust. Constitutes a suction check valve.
The atmospheric pressure sensor 30 measures the atmospheric pressure of the interior Ya and converts it into a voltage, and further converts it into a digital signal by a DA converter.
The control device 40 is configured by a microcomputer that controls the entire vehicle Y, and controls the air pump 10, the electromagnetic valve 21, and a sealing device Y10 described later by a program. The control device 40 functions as an automatic stop means, and is programmed to stop the operation of the air pump 10 when the atmospheric pressure sensor 30 reaches a predetermined value.
The automobile Y is structurally almost the same as an ordinary automobile, but the airtightness inside the vehicle is enhanced. In other words, the operating parts such as the accelerator, brake, clutch, shift lever, handle, etc. are designed to prevent the air from flowing properly to the outside by the seal member, unnecessary holes are blocked, and the door is also closed by raising the window. It is completely cut off from the outside air. In addition, a sealing device Y10 is provided at the outlet Ya1 of the air conditioner that inevitably communicates with the outside air. The sealing device Y10 has a lid for closing the air spout jetting port Ya1, and the lid is operated to be opened and closed by a driving means comprising a motor. Here, the sealing device Y10 is attached to the outlet Ya1 of the air conditioner. However, in addition to this, when there is a necessary opening portion with the outside, the sealing device Y10 is appropriately provided.

Next, a method of using the automobile Y equipped with the automobile temperature control device X having the above configuration will be described below. First, before the user parks the vehicle and leaves the vehicle, the user instructs the control device 40 to operate the vehicle temperature adjustment device X via a switch (not shown). At this time, it is selected whether the air pump 10 performs intake or exhaust. Generally, intake is performed in summer and exhaust is performed in winter. After giving instructions, the user goes out of the car and closes the door.
Here, when an instruction to perform intake is received, the control device 40 closes the sealing device Y10, opens the electromagnetic valve 21, switches the air pump 10 to intake air, and then operates the air pump 10. As a result, the pressure inside the vehicle Ya increases. This atmospheric pressure is measured by the atmospheric pressure sensor 30 and sent to the control device 40 as a digital signal. Eventually, when the atmospheric pressure reaches a constant value (here, 2 atmospheres), the control device 40 closes the electromagnetic valve 21 and stops the operation of the air pump 10. As a result, the interior Ya is maintained in a high pressure state. Thereafter, when the user returns to the vehicle and opens the door, the air in the vehicle Ya is expanded and released to the outside. That is, the air in the vehicle is almost adiabatically expanded, and thereby the temperature of the air in the vehicle consumes the energy of expansion and falls. By the operation as described above, the temperature inside the vehicle can be lowered in the summer.
On the other hand, if an instruction is given to exhaust before leaving the vehicle, the control device 40 closes the sealing device Y10, opens the electromagnetic valve 21, and switches the air pump 10 to exhaust, and then activates the air pump 10. Let Accordingly, the pressure inside the vehicle Ya becomes lower. This atmospheric pressure is measured by the atmospheric pressure sensor 30 and sent to the control device 40 as a digital signal. Eventually, when the atmospheric pressure reaches a constant value (here, 0.5 atmospheric pressure), the control device 40 closes the electromagnetic valve 21 and stops the operation of the air pump 10. Thereby, the interior Ya is maintained in a low pressure state. Thereafter, when the user returns to the car and opens the door, the air inside the car Ya is sucked in outside air and compressed. That is, the air in the vehicle is almost adiabatically compressed, and the temperature of the air in the vehicle is increased by releasing the compression energy. By the operation as described above, the temperature inside the vehicle can be raised in the winter.
In addition, when raising the pressure in a vehicle, the effect of crime prevention with respect to vandalism etc. can also be expected.

It is a conceptual diagram which shows the outline | summary of the structure of the motor vehicle carrying the temperature control apparatus for motor vehicles.
